Full textAbstract:
Marine natural resource and ocean species are endangered because of human activities. In order to avoid marine natural resource depletion and recover marine ecosystem, marine reserves are created. The report will introduce the marine reserve definition and its functions. In addition, the report will describe three main marine reserves in Australia. Moreover, it will explain why designating marine reserves is not an ecological process.

Full textAbstract:
We model marine reserve fishery linkages to evaluate the potential contribution of habitat-quality improvements inside a marine reserve to fish productivity and fishery catches. Data from Mombasa Marine National Park, Kenya, and the adjacent fishery are used. Marine reserves increase total fish biomass directly by providing refuge from exploitation and indirectly by improving fish habitat in the reserve. As natural mortality of the fish stock decreases in response to habitat enhancement in the reserve, catches increase by up to 2.6 tonnes (t)·km2·year1 and total fish biomass by up to 36 t·km2. However, if habitat-quality improvement reduces the propensity of fish to move out of the reserve, catches may fall by up to 0.9 t·km2·year1. Our results indicate that habitat protection in reserves can underpin fish productivity and, depending on its effects on fish movements, augment catches.

Full textAbstract:
Advances in electronic telemetry systems have led to fish tagging studies that are sufficiently long to provide estimates of natural mortality of many marine fishes. We used acoustic transmitters and an array of recording receivers to estimate natural mortality, residence times, and rates of movements of lingcod (Ophiodon elongatus) in a marine reserve in southeast Alaska. We surgically implanted acoustic tags in a total of 83 lingcod in December 1999 and July 2000, and distributed recording monitors with receiving ranges of at least 800 m throughout the reserve. The receivers were anchored on the seafloor in locations that resulted in overlapping receiving ranges, and thus created an array of receivers that completely encompassed an 8 km2 reserve. In this way, we were able to estimate natural mortality rates and track movements of tagged lingcod into and out of the reserve from December 1999 through October 2001. Acoustic tag results indicated that most of the tagged fish frequently left the reserve, but were only absent for short time periods. Tagged fish showed a high degree of site fidelity. The large number of signals received from tagged fish enabled us to generate models that provided a way to predict the effects of marine reserves on yield and eggs per recruit for a cohort of female lingcod.

Full textAbstract:
We use discrete-time models to investigate the impact of marine reserve establishment on fishery catch and biomass levels in open-access and quota-regulated fisheries under conditions of recruitment variability and natural mortality events. We find that under the conditions of variability tested, reserves can increase the probability of achieving target levels of biomass (60%, 35%, and 5% of carrying capacity) and can reduce catch variability in neighbouring fisheries, making future planning in the fishery more efficient. The size of the reserve required to meet each objective will depend on the initial condition of the stock and the exploitation rate in the fishery. Reserve coverage of between 20% and 40% prevent stock collapse in most cases. In heavily exploited fisheries, reserves are also likely to enhance mean catches, particularly in highly variable systems. If the stock has previously been heavily exploited, large reserves (≥60%) may be required to significantly increase the probability of achieving target biomass levels. However, once stocks have recovered, reserve coverage may be reduced without a reduction in this probability of success.

Full textAbstract:
SUMMARYStudies of marine reserves typically focus upon differences in the size and abundance of target organisms inside versus outside reserve borders, but they seldom provide spatially explicit measurements of how reserves influence mortality rates. This study investigated mortality rates for female California spiny lobster (Panulirus interruptus) at multiple sites inside and outside of three marine reserves at the Santa Barbara Channel Islands, California, USA. Mean total mortality (Z) of female lobsters was lower at sites inside reserves (Z = 0.22 [± 0.05 SE]) than at sites outside reserves (Z = 0.59 [± 0.02 SE]). Mean mortality at all sites inside reserves, and among sites near reserve centres (where Z = 0.17 [± 0.05 SE]), was similar to estimates of natural mortality for other temperate spiny lobster species. Among sites inside reserves, there was a positive relationship between mortality and proximity to reserve borders, but this relationship was absent among sites outside reserves. Mortality estimates were much more variable among sites inside reserves than at sites in fished areas. This variation is probably due to differential emigration rates from the three reserves, as well as site-specific ecological factors that influence population structure, demonstrating the importance of spatially explicit reserve sampling and understanding how ecological heterogeneity influences fisheries models.

Full textAbstract:
SUMMARYNational laws and institutions interact with local governance systems to encourage CBNRM in some cases while creating conflict in others. A case study of Kubulau District (Bua Province, Fiji) illustrates the challenges and successes of implementing traditional community-based natural resource management (CBNRM) within a pluralist legal and institutional context. In 2005, the communities of Kubulau established a network of protected areas, including 17 traditional closures (tabu), three no-take district marine reserves, a legally–declared forest reserve and a proposed forest reserve, managed under an integrated ‘ridge-to-reef’ plan. Marine and terrestrial areas in Kubulau illustrate synergies and discord between national laws and community management rules, and provide examples of management success and conflict. Key components influencing diverse management outcomes in Kubulau include (1) the legal status of customary resource tenure, (2) incorporation of local knowledge, traditions and priorities, (3) clearly articulated relationships between local decision-making processes and government regulation, and (4) perceived equity in distribution of management benefits. Legal and institutional reforms are proposed to improve management of natural resources in Fiji.

Full textAbstract:
Artificial reefs in marine protected areas provide additional habitat for biodiversity viewing, and therefore may offer an innovative management solution for managing for coral reef recovery and resilience. Marine park user fees can generate revenue to help manage and maintain natural and artificial reefs. Using a stated preference survey, this study investigates the present consumer surplus associated with visitor use of a marine protected area in Barbados. Two hypothetical markets were presented to differentiate between respondents use values of either: (a) natural reefs within the marine reserve or (b) artificial reef habitat for recreational enhancement. Information was also collected on visitors’ perceptions of artificial reefs, reef material preferences and reef conservation awareness. From a sample of 250 visitors on snorkel trips, we estimate a mean willingness to pay of US$18.33 (median—US$15) for natural reef use and a mean value of US$17.58 (median—US$12.50) for artificial reef use. The number of marine species viewed, age of respondent, familiarity with the Folkestone Marine Reserve and level of environmental concern were statistically significant in influencing willingness to pay. Regression analyses indicate visitors are willing to pay a significant amount to view marine life, especially turtles. Our results suggest that user fees could provide a considerable source of income to aid reef conservation in Barbados. In addition, the substantial use value reported for artificial reefs indicates a reef substitution policy may be supported by visitors to the Folkestone Marine Reserve. We discuss our findings and highlight directions for future research that include the need to collect data to establish visitors’ non-use values to fund reef management.

Full textAbstract:
Marine populations are typically connected over greater spatial scales than their terrestrial counterparts due to many species having a highly dispersive, planktonic larval phase. However, high levels of larval mortality in the plankton may reduce connectivity between populations. The effect of turbulence on larval mortality was investigated under natural conditions in a field experiment. Larvae were collected before and after being subjected to turbulent tidal flow from a marine reserve, with differential mortality being observed between taxa. Thin-shelled veligers of gastropods and bivalves showed significantly increased mortality, while barnacle nauplii and cyprids, bryozoan cyphonaute larvae and polychaete trochophores showed no effect of turbulent tidal transport. Where appropriate, marine reserve design should account for the reduced connectivity between populations associated with turbulent tidal transport between reserve and adjacent areas.

Population characteristics can be influenced by specific factors of the habitat and the natural variability of populations can confuse the effect related to protected environments. This study compares the demographic characteristics of Octopus tehuelchus in three coastal environments: two Marine Protected Areas (San Antonio Bay (SAB) and Islote Lobos (IL)) and a traditional fishing zone (El Fuerte (EF)). Weight–frequency distributions, sex-ratio and recruitment were monthly compared between the three intertidal zones. Octopus tehuelchus was smaller in IL, where fishing intensity is lower or null, and reached the largest sizes in the main fishing area of EF and within SAB (where there is no regulation and a mid–high fishing intensity). The sex proportion in SAB and EF was 1:1 all along the year. Although the proportion of mature females in IL was higher, the highest recruitment was observed in EF (the traditional fishing ground). These new data suggest that previous studies, which reported that Marine Protected Areas have positive effects for O. tehuelchus populations, can no longer be supported, and highlight the importance of understanding and quantifying the magnitude and range of natural variability in each environment when assessing the effectiveness of Marine Protected Areas.

Full textAbstract:
Worldwide, marine biological invasions of non-native species have increased significantly in recent years due to a rapid rise in global trade, transport and tourism. Invasions occur when non-native species are transported from one region to another and establish, often resulting in competition displacing native species and changing ecosystems. Historic literature searches were conducted along with dive surveys of the main ports and in sites around the archipelago in order to produce a baseline of which non-native species are present in the Galapagos Marine Reserve at this time. Confounding processes of anthropogenic and natural activities are increasing the potential spread of marine invasive species in the Eastern Tropical Pacific and the Galapagos Marine Reserve. We discuss the potential vectors facilitating marine invasions with the suggestion that marine traffic could be the most influential vector in the transport of marine non-natives to the Galapagos Marine Reserve. The challenge for marine park authorities is to identify those species that are likely to cause negative impacts on native biodiversity and ecosystems before they establish in the Galapagos, and to develop pre-emptive strategies that would likely include prevention as well as risk-based management strategies to remove them or to mitigate their harmful effects.

2006/2007L’obiettivo di tale studio è stato quello di implementare un Sistema di Informazione Geografica (GIS) per il monitoraggio dell’attività di pesca e delle risorse alieutiche, considerando le marinerie delle Isole Egadi, a rappresentanza di alcune tipologie di base dell’attività di pesca artigianale e per i diversi vincoli ambientali che in quest’area insistono quali la Riserva Naturale Marina e i Siti Natura 2000, al fine di suggerire opportune strategie di protezione sia per le risorse pescabili che per l’ambiente. Quindi un sistema esperto a supporto delle decisioni, che consenta di visualizzare i complessi scenari nell’ambito della valutazione delle risorse alieutiche nella dimensione spazio-temporale (Spatial Decision Support System), orientato alla pianificazione territoriale per un uso sostenibile delle risorse naturali, sinergica e coordinata tra i vari enti territoriali preposti. Nel corso di tale studio è stato messo a punto un data-warehouse, orientato alla pianificazione territoriale contenente differenti tipologie di dati ambientali, un database relazionale (RDBMS) contenente i dati riguardanti la pesca e la flotta, e un GIS in grado di gestire, analizzare, integrare dati eterogenei, riferendoli alle rispettive posizioni geografiche, finalizzato nello specifico ai seguenti obiettivi: - Studio delle caratteristiche ambientali dell’area di interesse; - Caratterizzazione della struttura della flotta per ciascun porto; - Variabilità degli attrezzi utilizzati nel tempo e nello spazio in ciascun porto; - Indagine delle specie catturate, qualitativamente e quantitativamente; - Indagine dello sforzo di pesca e cattura per unità di sforzo (CPUE), nello spazio e nel tempo; - Analisi dei principali parametri chimico-fisici ambientali (temperatura, salinità, ossigeno, etc); - Rilevazione delle condizioni climatiche e meteo-marine; - Individuazione di specie e habitat di elevato valore ecologico; - Valutazioni ambientali e indicazioni gestionali. In particolare, è stata indagata l’area di studio, gli aspetti geologici, biologici, con particolare rilievo ad habitat e specie di interesse scientifico e/o ecologico, mediante ricerche bibliografiche e campagne sperimentali in mare. Sono state realizzate le indagini inerenti la pesca e la flotta mediante i seguenti metodi: metodo indiretto e metodo diretto. Il metodo indiretto ha compreso la raccolta dei dati settimanalmente mediante rilevazione allo sbarco, per un intero anno. Il metodo diretto ha compreso la realizzazione di campagne sperimentali opportunamente pianificate, utilizzando come campionatore diverse tipologie di imbarcazioni e attrezzi delle marinerie dell’area, per la raccolta diretta di dati, sempre nell’arco di un anno. Durante le pescate sperimentali si è fatto uso di strumentazione GPS (Global Positioning System) per registrare le coordinate geografiche del punto iniziale, medio e finale dell’attrezzo in pesca. La profondità, a cui sono state effettuate le pescate, è stata registrata mediante ecoscandaglio. I dati oceanografici sono stati prelevati in situ, mediante sonde multiparametriche. Sono state rilevate informazioni riguardo le condizioni climatiche e meteo-marine. E’ stato realizzato un GIS facendo uso del software ArcGIS 9.1 della ESRI. Per la definizione dei temi e per uniformare le informazioni raccolte e catalogate nel datawarehouse, questo è stato strutturato in accordo ad un Thesaurus di Riferimento per Applicazioni ambientali (Environmental Applications Reference Thesaurus, EARTh). I dati riguardanti la pesca e la flotta sono stati elaborati e organizzati in un Database relazionale (RDBMS), che ha permesso la gestione dell’informazione geografica assicurando caratteristiche quali efficienza nelle prestazioni, controllo degli accessi, controllo delle ridondanze, conferendo una formidabile elasticità alla struttura e quindi di analisi spaziale, permettendo così di analizzare i diversi aspetti dei fenomeni. Questo è stato arricchito con collegamenti (hyperlink) a documenti utili (leggi, direttive, vincoli territoriali), immagini (foto di barche, coste, specie, attrezzi), pagine web. Infine, il sistema è stato organizzato in modo che, effettuando differenti interrogazioni ed operazioni quali analisi di dati spaziali (interpolazioni, operazioni di overlay, raster calculator), analisi degli attributi (query o funzioni di ricerca, SQL, summarize, statistics) e analisi integrata (spaziali e attributi), ha permesso di ottenere differenti informazioni nella dimensione spazio-temporale. In conclusione, il sistema è stato predisposto per analizzare e visualizzare i complessi scenari esistenti nell’ambito della valutazione delle risorse alieutiche nella dimensione spazio-temporale (monitoraggio), considerando le caratteristiche ambientali e le diverse problematiche dell’area, in modo da prevedere i possibili scenari futuri (forecasting) creando una modellizzazione della realtà, al fine di: fornire indicazioni nel pianificare una gestione ottimale delle risorse, razionale, integrata e sostenibile, quindi fornire spazialmente una scelta di soluzioni al decisore (Spatial Decision Support System) per la conservazione degli stock ma anche per preservare gli ecosistemi marini; avviare in caso di un’area sottoposta a più vincoli (Riserva Marina, Sito Natura 2000, IBA) una pianificazione concertata e sinergica tra i diversi livelli istituzionali preposti (governance multilivello e interscalare) ed evitare quindi una pianificazione conflittuale o ridondante. Il sistema realizzato potrebbe vedere applicazione nell’ambito delle seguenti pianificazioni: per la realizzazione dei piani di gestione pesca regionali, inerenti il Programma Operativo Pesca - FEP nazionale (Fondo Europeo per la Pesca); per l’elaborazione dei piani di gestione dei Siti Natura 2000; per la predisposizione delle varie fasi della Valutazione Ambientale Strategica (VAS); per la predisposizione di piani territoriali di Gestione Integrata della Fascia Costiera GIZC; nell’istituzione di Aree Marine Protette o Riserve Naturali Marine, Parchi, ed in particolare risulterebbe utile nella pianificazione della zonazione, soprattutto quando in tali aree è presente come forte componente l’attività di pesca, ricoprendo un elevato valore in termini di occupazione, commercio, attività ricreative e quindi di benessere economico.
The objective of this study was to implement a Geographic Information System (GIS) for the monitoring of fishing activities and alieutic resources in the Egadi Islands, as being representative of a few fundamental kinds of small-scale fishing and for various existing environmental restrictions such as the Marine Reserve and Natura 2000 sites. The purpose was to suggest appropriate conservation strategies for both alieutic resources and the environment. In other words, an expert system to decision support, making it possible to visualize complex scenarios in the assessment of alieutic resources in a space-time dimension (Spatial Decision Support System), geared towards spatial planning -for a sustainable use of natural resources- in synergy and coordination among the various authorities in charge. In the study a data-warehouse was set up, geared towards spatial planning and containing various categories of environmental data, a relational database (RDBMS) containing data on fishing and fleets, and a GIS capable of processing, analyzing and integrating heterogeneous data in reference to their respective geographical locations, with the following specific objectives: - Study of the environmental characteristics of the area of focus; - Characterization of the structure of the fleet for each port; - Investigating fishing gear changes in time and space in each port; - Quantitative and qualitative investigation of the species caught; - Analysis of fishing effort and catch per unit effort (CPUE), in time and space; - Analysis of the main environmental -physical and chemical- parameters (temperature, salinity, oxygen, etc.); - Survey of climatic and sea weather conditions; - Identification of species and habitats of high ecological value; - Environmental assessment and management guidelines. In particular, the investigation was carried out on the area of focus, its geological and biological aspects, with special attention to habitats and species of scientific/ecological interest, through bibliographic research and experimental sampling at sea. The investigation on fishing and fleets has been carried out with the following methods: indirect method and direct method. The indirect method has involved weekly collection of data from interviews at landing, over a whole year. The direct method has involved carefully planned sampling trips, using various types of boats and gear of the local fisheries for direct collection of data, also over a whole year. In the sampling process, a GPS (Global Positioning System) was used to record the initial, middle and final geographical coordinates of the fishing gear. Depths of experimental fishing were recorded with an echo sounder. Oceanographical data were obtained on site, with the use of multiparametric probes. Information has been recorded on climatic and sea weather conditions. The GIS was set up using ArcGIS 9.1 software by ESRI. For definitions of topics and to standardize the information collected and filed in the data-warehouse, this has been structured in accordance to the Environmental Applications Reference Thesaurus (EARTh). Data regarding fishing and fleets have been processed and organized in a relational database (RDBMS), which has made it possible to manage geographical information as well as assuring characteristics such as efficiency of performance, access control, redundancy control, thus giving the structure remarkable flexibility also in terms of spatial analysis and the possibility of looking at the various aspects of events. The database has also been enriched with hyperlinks to useful documents (laws, directives, planning restrictions), images (photos of boats, coastlines, species, gear), and web pages. Finally, the system has been organized so as to be able to obtain various kinds of information in a space-time dimension through operations and procedures such as spatial data analysis (interpolation, overlay, raster calculator), analysis of attributes (query or search functions, SQL, summarize, statistics) and integrated analysis (spatial data and attributes). In conclusion, the system has been set to analyze and visualize complex scenarios in the assessment of fishable resources in a space-time dimension (monitoring), taking into consideration the environmental characteristics and various critical factors of the area, so as to forecast possible scenarios and create models of reality with the purpose of: providing indications for optimal, rational, integrated and sustainable resource management, as well as a range of spatial options for decision-makers (Spatial Decision Support System) for the conservation of stock and marine ecosystems; in the case of areas subjected to multiple restrictions [Marine Reserve, Natura 2000 site, IBA (Important Bird Areas)], giving way to a concerted, synergic planning activity among the various authorities in charge (multi-level and inter-scalar governance) and thus avoiding any conflictual, redundant planning. Such system could be applied in the following planning situations: implementation of regional fishing management plans within the national Operational Programme – EFF (European Fisheries Fund); preparing of management plans for Natura 2000 sites; preparation of the various phases of Strategic Environmental Assessment (SEA); preparing of plans for the Integrated Coastal Zone Management (ICZM); institution of Marine Protected Areas or Marine Reserves, Parks, in particular, it would be useful to plan the zoning of this areas protected, especially when fishing activity is strong and of high value for occupation, trade, recreational activities and hence economic welfare.

The study reviews international experience of networks of marine protected areas (MPAs) and forms of Good Governance in protected areas and in networks of protected areas or systems, describes the characteristics of the Chilean sea, including its biodiversity, threats and public institutions related to marine protected areas; recognizing the existing governance model. It develops a questionnaire with questions regarding perceptions about the state of marine biodiversity; the role of different types of MPAs in marine conservation; the role of the state in funding; the most desirable leadership of a system of MPAs in the country; and selected key personnel of stakeholders participating in the establishment of MPAs to react to statements /questions. The statistical processing of the responses to the questionnaire helped to identify the perceptions of key stakeholders. These results, together with those from the study of international experience on MPA networks; Good Governance; the particularities of Chilean sea and existing institutions allowed to design a model of how a system could be organized, that articulate and lead, with Good Governance MPAs in the country. A system of MPAs should be part of a system of protected areas that well as articulate theterrestrial, maintaining a certain decisional autonomy. It recognizes three levels of decision making as desirable: local, regional and national levels. Each one of them must have a scope of issues that resolves in a participatory way, with representatives from its level, public and private. Offshore MPAs should be monitored from the national level. And those that are located in the Coastal Zone by the local and regional levels.

Marine populations worldwide are in decline due to anthropogenic effects. Spatial management via marine reserves may be an effective conservation method for many species, but the requisite theory is still underdeveloped. Integrodifference equation (IDE) models can be used to determine the critical domain size required for persistence and provide a modelling framework suitable for many marine populations. Here, we develop a novel spatially implicit approximation for the proportion of individuals lost outside the reserve areas which consistently outperforms the most common approximation. We examine how results using this approximation compare to the existing IDE results on the critical domain size for populations in a single reserve, in a network of reserves, in the presence of alongshore currents, and in structured populations. We find that the approximation consistently provides results which are in close agreement with those of an IDE model with the advantage of being simpler to convey to a biological audience while providing insights into the significance of certain model components. We also design a stochastic individual based model (IBM) to explore the probability of extinction for a population within a reserve area. We use our spatially implicit approximation to estimate the proportion of individuals which disperse outside the reserve area. We then use this approximation to obtain results on extinction using two different approaches, which we can compare to the baseline IBM; the first approach is based on the Central Limit Theorem and provides efficient simulation results, and the second modifies a simple Galton-Watson branching process to include loss outside the reserve area. We find that this spatially implicit approximation is also effective in obtaining results similar to those produced by the IBM in the presence of both demographic and environmental variability. Overall, this provides a set of complimentary methods for predicting the reserve area required to sustain a population in the presence of strong fishing pressure in the surrounding waters.

Marine protected areas are recognized as an important approach to conserve marine ecosystems and biodiversity as well as to manage costal and marine resource. This thesis addresses the development and management of marine protected areas in Australia and in China. Australia and China are major maritime countries with diverse marine creatures and ecosystems. Both countries have adopted marine protected areas as a management tool to protect the marine environment. This thesis introduces their marine environment and threats, and then makes a close study of the development, legislation and management of marine protected areas in both Australia and China. Two case studies, Jervis Bay Marine Park in Australia, and Shankou Mangrove Marine Nature Reserve in China provide examples of the management strategies and lessons learnt. In order to improve the management of marine protected areas in China, the thesis analyzes the conflicts in the development of marine protected areas in China and prescribes community participation and the marine special reserve as solutions to promote the development of marine protected areas. This study also examines how the Australian Defence Force, an important stakeholder, manages its activities in the marine protected areas.

Full textAbstract:
Trans-frontier conservation areas (TFCAs), large cross-border areas dedicated to biodiversity conservation, multi-national co-operation and development are expanding in southern Africa, fast becoming the dominant conservation solution in the region. TFCAs adopt a celebratory discourse of ecological, community, economic and political gains, while the reality is often far more complicated. This thesis situates the expansion of TFCAs within a critical political ecology approach, and argues that they represent a neoliberal solution to a complex series of development, environment and political challenges. Drawing on five and a half months of fieldwork to Mozambique along with policy and discourse analysis it examines the first marine reserve to be linked to a TFCA in Africa, the Ponta do Ouro Partial Marine Reserve (PPMR) in southern Mozambique. It makes three arguments: First, it argues that Mozambique’s embrace of TFCAs represents the neoliberalisation of conservation through novel tourism-based products, techniques of governance, creation of subject positions based on entrepreneurialism, and new arrangements of space. At the same time, the adoption of TFCAs also stems from Mozambique’s post-war politics, especially the ways in which elite state actors have sought to reconstruct and reorder the country through engagement with donors. Second, the thesis uses a combined governmentality and assemblage framework to explore how neoliberal conservation is made to cohere as a truth discourse, how it materially co-produces human and non-human life in the marine reserve, and how it is fragile, partial and contested. Third, it critiques the increasingly close relationship between the extractive and conservation sector at a policy, state and donor level, exploring how and why marine conservation is increasingly intertwined with Mozambique’s resources boom through its green economy discourse. Through these three points of engagement, the thesis contributes to debates around the intensifying relationship between extraction and conservation, Mozambique’s post-war development, and processes of neoliberalisation of nature.

Full textAbstract:
With an increasing understanding for the impacts of scuba dive tourism on the marine environments and local communities world-wide, research has recently expanded to include the perspectives of ecology, socio-culture and economy. However, due to the common lack of a transdisciplinary view, the following research aims at fulfilling the gap by viewing the management of scuba dive tourism at the two marine reserves of Bongoyo and Mbudya, Tanzania, through a sustainable perspective. Thereby, the research examines the ecological state of the marine environment as perceived by the scuba divers, the operation of scuba diving, as well as how scuba dive tourism relates to the major possibilities and challenges of the marine reserves. Supported in nature-based tourism management and the theories of recreation specialization and recreational succession, questionnaires were handed out to divers and interviews were conducted with stakeholders of the marine reserves, including a scuba dive operator, conservation groups and a private interest. The results portrayed degradation of the coral reef, with scuba diving constituting a minor influence, in comparison to the greater challenges of destructive fishing methods and lack of regulations. Thereby, the research illustrates scuba diving as a positive contributor to the marine environment, raising awareness on the need for conservation within both the local and the scuba diving community. Finally, the research concludes with proposals of sustainable management strategies for the operation of scuba diving within the marine reserves.

Full textAbstract:
This dissertation investigates social and ecological factors that facilitate effective management of coral reefs as social-ecological systems. Meta-analytical and field-based methods were employed to examine current management challenges and identify strategies that improve management effectiveness and coral reef health. A meta-analysis was used to evaluate biological indicators of reef health in relation to the types of fishing regulations in place (no-take areas, gear restriction areas, and periodic closures) and the actor groups (community-based, co-management, state, private) involved in management efforts for coral reef fisheries throughout the world. Other than enhancement of fish biomass within no-take areas that was significantly greater than in gear restriction areas, most biological indicators benefitted similarly from management techniques of no-take areas and gear restriction areas. Community-based and co-management were the best performing management arrangements for some biological outcomes but require further case studies to verify findings. Investigation of management effects by region indicated that previously degraded reefs received fewer benefits from management implementation than did relatively healthier reefs. For field investigations, the Comoros islands in the Western Indian Ocean served as a model for tropical coral reefs with challenging socioeconomic contexts, high biodiversity, and high vulnerability to coral reef degradation. Empirical study at 21 sites was used to identify the relative effects of natural and anthropogenic threats to coral reefs of the Comoros. Most previous studies of reef health focus on primarily natural factors or a single anthropogenic threat. This study examined suites of natural factors and human activities to identify the relative importance of each on reef health. Human activities including fishing, sand extraction, and beachfront housing and development were the best predictors of reef health status.
Most notably, human population and fishing predicted fish richness, abundance, and biomass with seasonal variation in the effects, while site orientation strongly predicted benthic cover. Field studies in the Comoros were also used to investigate the roles of community and state actors in co-management and compare effectiveness of comanagement across sites with varying levels of actor participation. Effective management was found to occur with community or `meta-community' (in this case, a Marine Protected Area in which the efforts of several communities were organized) participation in governance and support of state or external agents, while resilient management that overcame considerable challenges was found to occur only with strong community participation and leadership in governance. External agents were found to contribute to development of meta-community governance structure and initiation of community participation through education and capacity building. The findings from these studies reveal that coral reef management can be improved through context appropriate regulations that address detrimental human activities and through wide acceptance and participation in governance with cooperation among states, communities, and external agents.

Full textAbstract:
This thesis examines a participatory approach to interpretive planning, employed in the Shark Bay World Heritage Area, Western Australia. At the project outset relations between the conservation agency responsible for administering World Heritage and the local community were strained, and complicated by a history of conflict over the World Heritage listing and subsequent management of the area. A participatory approach to interpretive planning was adopted in the hope that doing so would achieve the following: improved relations between polarised stakeholder groups, increased community support for the plan and its implementation, and improved access to the variety of knowledge pools within the Shark Bay community. Effectively ongoing and integrating the interests of the area's polarised stakeholders meant that their social, political, organisational and disciplinary divisions had to be overcome. To do this, a novel participatory interpretive planning method was developed using action research. This method employed a combination of techniques, including a modified Delphi Technique based on indepth interviews, key informants, and direct prolonged emersion of the researcher in the community. The practical results of the project were the production of a stakeholder-derived communications strategy and interpretive plan for the World Heritage Area. These products embodied the collective social, cultural, economic and environmental interests of Shark Bay stakeholders, and included agreed-upon objectives, messages, stories for representing Shark Bar to the outside world. The participatory planning process also resulted in a number of instrumental and transformative outcomes including: surfacing of latent community issues, quieting of dominant rhetoric, identification of common values among stakeholders, collection of knowledge from multiple sources and contexts, equalisation of power between community segments, empowerment of marginalised community members, creation of social capital, and generation of support and commitment to plan implementation. In addition, the study demonstrated that participatory processes are vulnerable to cooption and manipulation by powerful stakeholders, and that the success of such processes relies more on the creation of trusting relationships (i.e. social capital) between stakeholders and facilitators than on the application of formulaic group techniques used to garner public input. With respect to interpretive planning, this project showed how a participatory approach to interpretive planning can be used as an ethical means to develop multiple narratives for interpretation that are just and legitimate representations of the community’s interests and stories. Other implications of this project, particularly in relation to the creation of social capital and horizontal and vertical relationships between community and agency groups, indicate that participatory interpretive planning can be used as an intervention in situations where conservation initiatives have resulted in conflict with local communities. Positive change is achieved through the creation of a common platform of values, mutual understanding and knowledge, from which further dialogue and reciprocal cooperation can take place. The evidence presented suggest that the stakeholder-centred approach to interpretive planning used in Shark Bay may form a useful basis for collaborative environmental management in a range of contexts and landscapes where new conservation initiatives are being contemplated. Lessons learned through application of this novel approach to interpretive planning may prove useful to interpretive professionals, environmental managers, governments and businesses attempting cross-disciplinary integration of multiple stakeholder interests.

Full textAbstract:
Although the marine environment has generally been considered to be less in need of attention from conservationists, politicians and managers than the terrestrial environment, there has been an increasing appreciation that there is little left in the marine environment that can be considered unaltered by humans. Conservation action is therefore urgently needed to protect marine populations, species and environments from anthropogenic pressures. Since overharvesting seems to be the main cause of the collapse in coastal ecosystems, areas need to be protected so that stocks can recover. However, the proclamation of such marine protected areas (MPAs) need to be well planned to ensure that species are well represented and that their biological requirements are met in the long term. While terrestrial conservation planners have started to incorporate biological, social and economic information into so-called systematic conservation plans, marine planners have been more hesitant to use these approaches due to the greater openness of the ocean (with the associated greater dispersal of marine organisms and propogules, lower levels of endemism, and lack of ownership) and the paucity of available information. The current study aimed to investigate the applicability of systematic approaches to the process of selecting sites for a network of potential replenishment zones for seabream species that could supplement protection already afforded by existing no-fishing reserves. Since many of these seabream species are popular targets in both the recreational and commercial linefishery sectors, they have been overexploited and are in need of additional protection. Information on these species and the diversity of their associated reefs were obtained through consultations with scientists, managers and resource-users (namely SCUBA divers, spearfishers as well as recreational and commercial fishers). These data were obtained during workshops where Participatory Rural Appraisal (PRA) scoring and mapping methods were applied. Although ordinal-scale, rather than interval-or ratio-scale data were obtained, these data could be used in an interactive selection process. Because these methods require relatively cheap materials and few personnel, they could be used to collect information where limited budgets are available. Quantitative targets for the protection of individual species were set on the basis of their status in the Marine Living Resource Act, since this reflected their different requirements for protection. A preliminary investigation indicated that the current no-fishing reserves effectively achieved most of these goals for seabream species. The selection of sites for the replenishment network was based on irreplaceability analyses, while decisions between sites with lower irreplaceability values were based on explicit design rules. A total of 26 sites were required to achieve targets for all species. These replenishment zones could potentially be established, managed and monitored by voluntary community groups. This study therefore indicated that systematic conservation planning can successfully be applied to the marine environment, while the involvement of stakeholders is crucial to ensure that conservation action is supported.

AbstractEl Hierro has been characterized by the balance between human development and environmental sustainability. The island was historically far from the mass tourism developments dominant on the other Canary Islands. Tourism accommodations in El Hierro are few compared to more developed coastal areas in the Archipelago, and recreational activities are mainly linked to cultural and natural sites and resources. This chapter focuses on La Restinga fishing village and its coasts, where the ‘Sea of Calms’ and one multiple-use Marine Reserve (MR) are located, both of which became popular over the last decade. The tourist development experience has promoted a new way of looking at the sea and conceptualizing its habitats and populations. In 2014, after the submarine volcano eruption occurred in 2011, we estimated that at least 25,391 dives had been carried out in the diving spots established by the MR and other diving sites close to La Restinga. Despite the difficulties experienced after the volcano eruption, a unique imaginaire has been consolidated, thanks to the image of the island's exclusive nature and iconic elements. In addition, the rapid recovery of the destination is an excellent example of how the tourism system can adapt and incorporate unexpected events such as volcanic eruptions.

<i>Abstract</i>.—Marine resource managers and environmental policy makers trained in disciplines grounded in the natural sciences learn quickly that some of the biggest challenges to the practice of ecosystem management are social ones. While ecosystem theory provides a conceptual framework for integrating the ecological, socioeconomic, cultural, and institutional elements of environmental problems, the <i>practice </i>of ecosystem management remains elusive. A potential model for addressing these challenges of ecosystem management is a U.S. “science to management” initiative of the National Oceanic and Atmospheric Administration implemented within the National Estuarine Research Reserve System. The Coastal Training Program initiative provided the context for this study’s development of innovative interdisciplinary approaches supporting ecosystem management to mitigate land-based pollution impacts in coastal watersheds in the Gulf of Maine.

Abstract This chapter focuses on the possibilities of restoring nature. It shows possibilities of cohabitation between the numerous human and rapidly shrinking wild ape populations, such as with the Orangutan Foundation preserving habitat, releasing orphaned orangutans in protected reserves, and promoting education and livelihoods for the locals. Rewilding and restoration need concerted efforts to accommodate natural landscapes and wild animal and plant populations, and to avert a mass extinction. The chapter explores, too, the possibility of building mutualistic ‘garden’ cities and rebuilding marine ecosystems such as those of mangrove and seagrass. For a sustainable future, the human and natural worlds need sensitive and imaginative rebalancing.

Full textAbstract:
The Danube Delta is the newest land formed by both transporting sediments brought by Danube River, which flows into the Black Sea and by traversing an inland region where water spreads and deposits sediments. Diurnal tidal action is low (only 8–9 cm), therefore the sediments would wash out into the water body faster than the river deposits it. However, a seasonal fluctuation of water level of 20 cm was observed in the Black Sea, contributing to alluvial landscape evolution in the Danube Delta. The Danube Delta is a very low flat plain, lying 0.52 m above Mean Black Sea Level with a general gradient of 0.006 m/km and only 20% of the delta area is below zero level. The main control on deposition, which is a combination of river, wind-generated waves, and tidal processes, depends on the strength of each one. The other two factors that play a major role are landscape position and the grain size distribution of the source sediment entering the delta from the river. The Danube Delta is a natural protected area in the South-Eastern part of Romania, declared a Biosphere Reserve through the UNESCO “Man and Biosphere” Programme. Water is a determining factor for all the human settlements in the Biosphere Reserve, the whole Danube Delta being structured by the three branches of the Danube (Chilia, Sulina and Sfantu Gheorghe (Saint George)). Our case study is focused on the Sulina branch, also named Sulina Channel, which offers the shortest distance between the Black Sea (trough Sulina Port) and Tulcea (the most important city of the Danube Delta from economic, social and cultural points of view) for both fluvial and marine ships. The improvement of water resources management is the main topic of this chapter, in terms of water quality indicators, which will be presented in twenty-nine monitoring points, starting since a few years ago and updated to nowadays. During the study period, significant exceedances of the limit value were detected in case of nitrate-N (3.9–4.6 mg/L) at the confluence (CEATAL 2) with the Saint George branch and in the Sulina Channel after the Wastewaters Treatment Plant (WWTP) discharge area, as well as near two settlements, namely Gorgova and Maliuc. The higher concentrations of Nitrogen-based nutrients were caused by the leakage from the old sewage systems (where these exist) and the diffuse loads.

Full textAbstract:
Diving tourism has been very popular in the world and Turkey. In addition to reasons such as seeking hobbies and socializing, marine biodiversity, natural reefs, wrecks, and corals cause more and more people to dive every day. In many regions in Turkey, which has many underwater riches, diving is prohibited for reasons such as archaeological and military zones and natural reserves. Therefore, alternative diving points have been created for diving tourism by using artificial reefs in recent years. Within the scope of 35 artificial wreck reefs, in which diving tourism has been carried out in Turkey, 3000 amphoras, many thematic sculptures, 22 ships, 9 planes, and 1 tank were launched. While decommissioned vehicles were used in the first years, underwater parks with different themes have been created in recent years. In this study, artificial wreck reefs in Turkey were examined, and the permit process, the structures, and the interests of divers were evaluated. In addition, mistakes made in material and location selection and interactions with other sectors are also discussed.

Full textAbstract:
Abstract Ordos basin in central China is well known for its rich accumulation of natural resources, including Triassic tight oil and Permian tight gas. A recent exploration breakthrough shows that Ordovician shale in the same basin is also promising. The purpose of this study is to capture the engineering details of two horizontal exploration wells exploration in Wulalike formation, which mark the first production of marine shale gas in Ordos basin. The Ordovician Wulalike formation in the Ordos basin was previously seen as source rock. During early exploration in the 2010s, the formation was found to be gas bearing. However, the Wulalike shale formation shows very different features compared to the Triassic lacustrine shale in the same basin and the Silurian marine shale from Sichuan. The abundance of natural fissures, the low reservoir pressure, and the tendency to produce water are unique challenges and concerns for the Wulalike shale formation. Based on the pilot well evaluations, two horizontal wells were drilled and completed in the Wulalike formation in different locations in the western Ordos basin in 2019–2020. Both wells were well-landed in the target zone and were completed with multistage large-scale fracturing treatments. Following the well completions, flowback and production tests lasted for 3 to 5 months. Production tests showed that well 1 reached an economically acceptable gas rate in natural flow for a long-term period, producing 20,000 to 60,000 std m3/d, and well 2 produced good gas in the early period but was soon overwhelmed by massive water production. Both wells were evaluated with production logging tools. In well 1, fiber-optic distributed acoustic sensing (DAS) and distributed temperature sensing (DTS) were used, and in well 2, a production logging tool (PLT) was used. The positive gas production from both wells marks the first production of marine shale gas in the Ordos basin. The understanding of the geology and reservoir, the use of unconventional fracturing and completion practices, the assistance of energized fluid, and post-treatment artificial lift are the technologies that helped achieve this success. Further study is needed on the complexity of the natural fissures to lower the risk of unwanted water production from the Wulalike rocks. The first successful production from the Wulalike is very critical for the exploration of the Ordovician section in the Ordos basin because it helps to confirm a favorable exploration and appraisal area of 2000 to 3000 km2, which has the potential to turn into a huge reserve. This case study provides value from a technical standpoint, as very few success stories have been reported from low-pressure shale gas previously in China or worldwide.

Full textAbstract:
Depleting oil reserves in shallow waters, off-shore oil fields are opening the avenues of new ventures in deep sea conditions. A marine riser is a major component of an offshore drilling and production system that are either fixed or floating in nature. Deepwater risers are quite long and significant currents usually excite natural bending mode that is much higher than the fundamental bending mode. In ultra deep environment currents usually change in magnitude and direction with depth, thereby inducing possibility of exciting multiple modes of the riser vibration due to VIV. Vortex induced vibration analysis has been carried out of a long marine riser in a probable deep sea location. To improve the understanding under deepwater harsh environments, the behavior of the riser under these forces is thoroughly investigated. 3D Nonlinear dynamic analysis of riser is obtained in the time domain using finite element software package ABAQUS/Aqua. The response histories so obtained are employed for the study of fatigue reliability analyses of riser. Uncertainty modeling, especially of fatigue crack growth parameters, is undertaken using bi-linear crack growth relationship. Results pertaining to fatigue reliability and fatigue crack size evolution are presented using Monte Carlo Simulation. The bi-linear crack growth models are found to lead to higher fatigue life estimation. Sensitivity behavior pertinent to limit state adopted has been thoroughly investigated. These findings implicate inspection schemes for components of the marine structures to ensure minimization of the surprises due to wide scatter of the fatigue phenomenon in marine environment.

Full textAbstract:
Arctic Escape, Evacuation, and Rescue (EER) is receiving more attention with the current resurgence of interest in Arctic offshore hydrocarbon reserves, marine tourism and shortening marine transportation routes. Since 2000, Transport Canada supported the Arctic EER research project for which the second author’s company has been the lead contractor. The research conducted under this program resulted in the development of Canadian performance-based standards for offshore petroleum installations and a computer model capable of assessing the reliability and performance of EER processes. The ISO, under Working Group 8, developed a Final Draft International Standard addressing Arctic Offshore Structures which is expected to be published in late-2010. The Standard addresses design requirements and assessments for Arctic offshore structures used by the petroleum and natural gas industries worldwide to help ensure that appropriate reliability levels are achieved for manned and unmanned offshore structures, regardless of the type of structure. The EER provisions of the Standard are intended to promote the successful escape from the incident, subsequent evacuation from the installation (emergency or precautionary evacuation), and the ultimate rescue of installation personnel. The EER provisions are performance-based. The Standard specifies design requirements and also provides background to and guidance on the use of the document.

Full textAbstract:
Abstract With energy shortages and increasing environmental problems, natural gas, as a clean energy, has the advantages of cheap price and large reserves and has become one of the main alternative fuels for marine diesel engines. For large bore natural gas engines, pre-chamber spark plug ignition can be used to increase engine efficiency. The engine mainly relies on the flame ejected from the pre-chamber to ignite the mixture of natural gas and air in the main combustion chamber. The ignition flame in the main combustion chamber is the main factor affecting the combustion process. Although the pre-chamber natural gas engines have been extensively studied, the characteristics of combustion in the pre-chamber and the development of ignition flame in the main combustion chamber have not been fully understood. In this study, a two-zone phenomenological combustion model of pre-chamber spark-ignition natural gas engines is established based on the exchange of mass and energy of the gas flow process in the pre-chamber and the main combustion chamber. The basic characteristics of the developed model are: a spherical flame surface is used to describe the combustion state in the pre-chamber, and according to the turbulent jet theory, the influence of turbulence on the state of the pilot flame is considered based on the Reynolds number. According to the phenomenological model, the time when the flame starts to be injected from the pre-chamber to the main combustion chamber, and the parameters such as the length of the pilot flame are analyzed. The model was verified by experimental data, and the results showed that the calculated values were in good agreement with the experimental values. It provides an effective tool for mastering the law of flame development and supporting the optimization of combustion efficiency.

Full textAbstract:
Interests in exploration and production of oil and gas in cold climate areas has increased in recent times. This can be attributed to the continual depletion of reserves in mature fields, and recent discoveries of large quantities of oil and gas in the cold climate region, including the more recent discovery of the Alta Reservoir, in the Barents Sea. However, marine operations in this region are faced with challenges resulting from its arctic conditions. Knowledge of the physical environment is important in designing offshore structures, and in planning, and executing marine operations. Selection of a suitable field development concept may be influenced by the probability of occurrence of rare events, such as drifting icebergs. Furthermore, occurrence of mesoscale phenomenon such as polar low pressures may adversely affect planned marine operations. In addition, uncertainties in weather forecasting will reflect on the available weather window to perform installation and interventions works. This paper presents some of the challenges in designing and planning for marine operations in the cold climate region. A possible field development concept for the open water areas of the Norwegian sector of the Barents Sea is discussed. The current research work considers the need for further assessment of the probability of occurrence of drifting icebergs as of importance when selecting field development concept. The Floating Production Storage and Offloading (FPSO) is proposed, and this should be designed with an internal turret system that can be disconnected and reconnected. Some of the challenges associated with riser systems design when considering a turret system with the capability to disconnect and reconnect are discussed. This paper also propose the use of ensemble forecasts as an alternative to the use of alpha factors to estimate operational weather window when planning for marine operations in the Barents Sea. The unpredictability nature of the environmental conditions, especially in the early winter is considered a challenge to marine operations.

Full textAbstract:
Abstract The heterogeneous nature of oil shale resources associated to the depositional environments, lithology, and organic content make the reserve estimation complex and unpredictable. However, comprehensive laboratory studies on organic rich shale samples collected from different regions can increase the understanding about the organic content of oil shales, interaction of shale with organic matter and injected fluid used during enhanced oil recovery method. This study investigates the characterization of eight different Turkish and American oil shale samples with several spectral methods and a thermal analysis. The main purpose of this study is to characterize the oil shale samples to increase the understanding about the organic content and interaction of shale with organic matter. In this study, we used Thermal Gravimetric Analysis/Differential Scanning Calorimetry (TGA/DSC) analysis to estimate organic content of each oil shale sample in air and nitrogen environments. X-Ray Diffraction (XRD) was used to define minerals in oil shale. Fourier Transform Infrared Spectroscopy (FTIR) was used to detect the mineral and kerogen in oil shale before and after the TGA/DSC analysis. Scanning Electron Microscope (SEM) was used to characterize the depositional environment of each oil shale samples. TGA/DSC results verified that oil shale samples have up to 50% of organic matter. XRD and FTIR results helped to identify the organic and inorganic compounds. Effects of minerals and ions were recognized by comparing TGA/DSC curves and FTIR spectra. It was recognized that the more carbonate ion in the oil shale the more increase in weight loss occurred. Diatoms identified from SEM results showed that depositional environments of the some oil shale samples are marine environments. This study provides insight for the reserve estimation of the eight different oil shale samples with comprehensive spectral and thermal characterization.

Full textAbstract:
Abstract A mathematical model is presented to predict the formation of gas hydrates in porous media under various boundary conditions. The new mathematical modeling framework is based on coupling the analytical pore network approach (APNA) and equation proposed by De La Fuente et al. [1]. Further, we also integrate thermodynamic models to capture the phase boundary at which the formation of gas hydrates takes place. The proposed analytical framework is a set of equations that are computationally inexpensive to solve, allowing us to predict the formation of gas hydrates in complex porous media. Complete governing equations are provided, and the method is described in detail to permit readers to replicate all results. To demonstrate the formation of hydrates in porous media, we analyzed the saturation of hydrates in porous media with different properties. Our model shows that the hydrate formation rate is positively related to the porous media's pore size. The hydrates were found to be preferably formed in the porous media composed of relatively larger pores, which could be attributed to the weak capillary forces resisting the formation of hydrates in porous media. The novelty of the new analytical model is the ability to predict the gas hydrates formation in porous media in a reasonable time using standard engineering computers. Furthermore, the model can aid in the estimation of natural gas hydrate reservoirs, which offer the avenue for effective methane recovery from the vast natural gas hydrate reserves in continental margins.

Full textAbstract:
Abstract Upstream developments in prolific oil and gas fields are highly profitable and hence attract various investors/partners, whereas Downstream developments profitability is margin based and challenging under certain situations to receive similar interest for investment in the same location. Vertical Integration Strategy implementation through hybrid upstream and downstream concession agreements can help address this issue. The seventies witnessed major changes in the oil industry's structures and strategies resulting from the nationalization of oil and gas reserves. This ultimately led to a separation between the upstream sector with national oil companies (NOCs) controlling most of the world reserves and crude production, and the downstream sector with the international oil companies (IOCs) controlling the largest share of the refining and marketing aspects in the main consuming countries. In the recent past, NOCs have started forward integration of its upstream sector with downstream sector to take advantage of the synergies and increase profitability. This paper takes the strategy a step more forward by exploring the possibility of developing oil and gas assets through a hybrid upstream/downstream concession agreement that can be awarded by the host government. The model hybrid agreement is built by integrating a typical upstream concession agreement with downstream equity-based joint venture (JV) agreement. It also takes the learnings from Production Development Production Sharing Agreement (DPSA) applied in the development of a Gas-To-Liquids (GTL) asset or Liquefied Natural Gas (LNG) asset which are usually developed as an integrated upstream and downstream business model. It is also feasible to build the hybrid agreement based on upstream Production Sharing Agreement (PSA) instead of a Concession Agreement. The paper will discuss how the hybrid upstream and downstream concession agreement is built and how it will distribute the risk and rewards across the entire value chain for investors, expand the scope of investment and support in the economic development of the host country.

Full textAbstract:
Mechanical damage is generally considered to be damage that occurs to a pipeline when mechanical excavation, drilling, or boring equipment impinges on a buried pipeline creating scrapes, abrasions, gouges, punctures, and/or dents in the pipeline. Above ground pipelines may also be damaged in a similar manner from impacts by vehicles or projectiles or by willful acts of vandalism. In some cases, immediate failure will occur resulting in potentially catastrophic consequences. It is thus important to understand the conditions that would lead to such a failure in order to ensure that design parameters are selected such that immediate failures occur very rarely. In cases where the damage does not create an immediate failure or the release of gas, the concern generally is that a delayed failure will occur because the integrity of the pipeline has been significantly compromised. In such cases, the possibility is that repeated pressure fluctuations, small increases in pressure, or time-dependent creep will erode whatever margin of safety remains and a failure will ensue. Particularly unsettling are the cases in which damage of this nature is encountered through some form of inspection where the source of the damage and its time of creation are unknown. In such cases, the operator of the pipeline will generally not know what margin of safety remains. There are a number of models in existence that may be used to predict both instantaneous and delayed failures due to mechanical damage and indeed these have been used quite extensively as the basis of repair criteria and for determining safe pipeline operating conditions. Nonetheless, there are significant elements of uncertainty associated with these models and for this reason an adequate reserve factor needs to be incorporated or recourse must be made to probabilistic approaches that address such uncertainty. However, since pipelines are getting older and in some cases are being operated at higher pressures than they were previously, there is a requirement to obtain a better understanding of the significance of mechanical damage. In view of this Pipelines Research Council International (PRCI) and other research bodies, such as European Pipelines Research Group (EPRG), are taking a keen interest in this topic. To this end, PRCI have commissioned an extensive research program to investigate all key aspects of both instantaneous and delayed failures. Kiefner and Associates Incorporated (KAI) and Andrew Francis and Associated Ltd (AFAA) were commissioned to investigate the conditions that cause instantaneous failures. The purpose of this paper is to describe the approach that was adopted and the formulation of the new model that emerged from study. This model is being validated through testing which is currently ongoing.

Full textAbstract:
Channel Islands National Park (CHIS) has conducted long-term ecological monitoring of the kelp forests around San Miguel, Santa Rosa, Santa Cruz, Anacapa and Santa Barbara Islands since 1982. The original permanent transects were established at 16 sites between 1981 and 1986 with the first sampling beginning in 1982, this being the 33rd year of monitoring. An additional site, Miracle Mile, was established at San Miguel Island in 2001 by a commercial fisherman with assistance from the park. Miracle Mile was partially monitored from 2002 to 2004, and then fully monitored (using all KFM protocols) since 2005. In 2005, 16 additional permanent sites were established to collect baseline data from inside and adjacent to four marine reserves that were established in 2003. Sampling results from all 33 sites mentioned above are included in this report. Funding for the Kelp Forest Monitoring Program (KFM) in 2014 was provided by the National Park Service (NPS). The 2014 monitoring efforts utilized 49 days of vessel time to conduct 1,040 dives for a total of 1,059 hours of bottom time. Population dynamics of a select list of 71 “indicator species” (consisting of taxa or categories of algae, fish, and invertebrates) were measured at the 33 permanent sites. In addition, population dynamics were measured for all additional species of fish observed at the sites during the roving diver fish count. Survey techniques follow the CHIS Kelp Forest Monitoring Protocol Handbook (Davis et al. 1997) and an update to the sampling protocol handbook currently being developed (Kushner and Sprague, in progress). The techniques utilize SCUBA and surface-supplied-air to conduct the following monitoring protocols: 1 m2 quadrats, 5 m2 quadrats, band transects, random point contacts, fish transects, roving diver fish counts, video transects, size frequency measurements, and artificial recruitment modules. Hourly temperature data were collected using remote temperature loggers at 32 sites, the exception being Miracle Mile where there is no temperature logger installed. This annual report contains a brief description of each site including any notable observations or anomalies, a summary of methods used, and monitoring results for 2014. All the data collected during 2014 can be found in the appendices and in an Excel workbook on the NPS Integrated Resource Management Applications (IRMA) portal. In the 2013 annual report (Sprague et al. 2020) several changes were made to the appendices. Previously, annual report density and percent cover data tables only included the current year’s data. Now, density and percent cover data are presented in graphical format and include all years of available monitoring data. Roving diver fish count (RDFC), fish size frequency, natural habitat size frequency, and Artificial Recruitment Module (ARM) size frequency data are now stored on IRMA at https://irma.nps.gov/DataStore/Reference/Profile/2259651. The temperature data graphs in Appendix L include the same graphs that were used in past reports, but include additional violin plot sections that compare monthly means from the current year to past years. In addition to the changes listed above, the layout of the discussion section was reordered by species instead of by site. The status of kelp forests differed among the five park islands. This is a result of a combination of factors including but not limited to, oceanography, biogeography and associated differences in species abundance and composition, as well as sport and commercial fishing pressure. All 33 permanent sites were established in areas that had or were historically known to have had kelp forests in the past. In 2014, 15 of the 33 sites monitored were characterized as developing kelp forest, kelp forest or mature kelp forest. In addition, three sites were in a state of transition. Two sites were part kelp forest and part dominated by Strongylocentrotus purpuratus...

Estamos ante una encrucijada global de proporciones nunca vistas. El planeta se calienta más rápido de lo esperado y enfrentamos condiciones climáticas cada vez más extremas, lo que pone en riesgo la sostenibilidad de la vida humana en el mediano y largo plazo. El nivel de los océanos está aumentando, los arrecifes de coral están muriendo, las especies se están extinguiendo, los glaciares se están derritiendo y las condiciones climáticas extremas se hacen cada vez más frecuentes con intensas olas de calor, inundaciones, huracanes, incendios y/o sequías. Para hacer frente a esta compleja situación, todos, personas e instituciones en los ámbitos nacional, regional y global, tenemos que hacer nuestra parte para evitar llegar a un punto de no retorno. Aunque Colombia solo genera el 0,6 % de los gases de efecto invernadero (GEI), es uno de los veinte países más amenazados por la crisis climática. Nuestro país alberga el 50 % de los páramos del mundo y es catalogado como una potencia en agua, biodiversidad y ambiente, aloja alrededor del 10 % de la fauna y flora del mundo, teniendo por ello un rol central en los esfuerzos globales que se realizan para mitigar los efectos del cambio climático. También es reconocido por ser el segundo país con más alta presencia en biodiversidad en la tierra, goza de dos océanos, cinco vertientes hidrográficas, ríos, lagunas y ciénagas, siendo de esta manera el agua un recurso fundamental para el desarrollo de las generaciones futuras. El país cuenta con grandes extensiones de páramos, los cuales son la fuente del 70 % de agua dulce en nuestro país y comparte al sur de nuestras fronteras con la Amazonía, considerada la selva tropical más extensa del planeta y el pulmón del mundo. Una porción representativa de ese 10 % del total de la biodiversidad mundial que tiene nuestro país, se encuentra dentro del Sistema Nacional de Áreas Protegidas (SINAP), del que hace parte el Sistema de Parques Nacionales Naturales y las Reservas Forestales (más de 17 millones de hectáreas), una fuente importante de bienes y servicios ecosistémicos, entre los cuales, el suministro del recurso hídrico incluye más del 62 % de los nacimientos de los acuíferos nacionales y abastece a casi un 80 % de la población colombiana. Así mismo, protege lagunas y ciénagas que contienen el 20 % de los recursos hídricos que abastecen la generación de energía eléctrica del país. En estas áreas protegidas se conservan muestras representativas de los ecosistemas naturales marinos y continentales, los cuales, además de albergar un gran número de especies de fauna y flora, contribuyen a la regulación del clima y protegen las cuencas hidrográficas. Es así como por su especial importancia ecológica, los Parques Nacionales Naturales tienen la función de conservar, proteger y salvaguardar sus ecosistemas de especial valor por medio del Estado y de los particulares. Esta gran riqueza ambiental del país está siendo amenazada por el uso indebido de los recursos naturales, lo que genera un acelerado deterioro de los ecosistemas, alterando su funcionalidad y poniendo en riesgo la biodiversidad. Esta problemática se ha convertido en un reto de primer orden para el Estado colombiano, sus autoridades ambientales y la sociedad en general. El Sector Defensa no ha sido ajeno a esta realidad, por lo que en el marco definido por la ley, la Presidencia de la República y el Ministerio de Ambiente y Desarrollo Sostenible, ha reconocido el potencial desestabilizador de las afectaciones causadas por las diversas actividades ilícitas de los Grupos Armados Organizados (GAO), los Grupos Delincuenciales Organizados (GDO) y ciudadanos que hacen un uso indebido de los recursos naturales. Fenómenos como la siembra de cultivos ilícitos, la extracción ilícita de minerales, la tala indiscriminada, la ganadería extensiva, el acaparamiento de tierras, la pesca ilegal, la contaminación, el vertimiento de sustancias peligrosas y el tráfico ilegal de flora y fauna, han debilitado los ecosistemas nacionales. Estas actividades ilegales afectan los recursos hídricos del país, los suelos, los páramos y la atmósfera, produciendo efectos negativos que generan deforestación, pérdida de hábitats, extinción de especies, la destrucción de fuentes de agua, el deterioro de las tierras de cultivos e impactos negativos en las reservas forestales y las áreas que integran el Sistema Nacional de Áreas Protegidas (SINAP). La degradación ambiental que hemos visto no solo es utilizada por las organizaciones criminales para obtener recursos que les permiten sostener su accionar delictivo en diversas zonas del país, más grave aún, se constituye en un atentado directo contra el porvenir de las generaciones futuras. Es por ello que el Sector Defensa ha reconocido el agua, la biodiversidad y el medio ambiente como activos estratégicos de interés nacional, con un carácter principal y prevalente, buscando apoyar con sus capacidades a las autoridades ambientales del país, con el fin de realizar acciones cada vez más eficaces contra las organizaciones criminales responsables del deterioro ambiental. Es en ese contexto surge la idea de este libro, que busca presentar la problemática que se enfrenta y visibilizar las acciones realizadas por el Sector Defensa en coordinación con las autoridades ambientales, con el fin de apoyar la defensa de estos activos estratégicos, así como prevenir los daños futuros a los mismos, en aras de trabajar en la protección de los recursos naturales, bajo una visión multidimensional de la seguridad. El Ministerio de Defensa (MDN) ha sido consciente de los desafíos climáticos a los que se enfrenta, no solo el Sector, sino el territorio nacional, en cuanto a los impactos cada vez mayores derivados de las condiciones meteorológicas extremas y la explotación de los recursos. Por ello, el Sector ha trabajado para alinearse con la Política Nacional de Cambio Climático, los compromisos del país ante la Contribución Nacionalmente Determinada (NDC), el cumplimiento del CONPES 4021 de diciembre de 2020 para el Control de la Deforestación y la Gestión Sostenible de Bosques, para así aportar con acciones de adaptación, mitigación y gestión del riesgo ante el cambio climático y variabilidad climática mediante del Plan de Gestión de Cambio Climático del Sector Defensa (PIGCCSD). Este libro reúne los principales resultados del Sector Defensa en materia de protección del medio ambiente y resalta la articulación de las políticas, así como de la operativización de las mismas por parte de las Fuerzas Militares y la Policía Nacional, por la protección de los recursos naturales de la Nación, una responsabilidad que ha quedado claramente plasmada en la “Estrategia Artemisa”, que es un esfuerzo permanente, sostenido, conjunto, coordinado, e interinstitucional que permitirá proteger y defender el agua, la biodiversidad y el medio ambiente como activos estratégicos de la Nación, a partir de la lucha contra la deforestación, sus causas directas o subyacentes y contrarrestar los efectos del cambio climático, como también la lucha contra la explotación ilícita de minerales, contra los cultivos ilícitos que afectan el medio ambiente y el conjunto de actividades de control y vigilancia que apoya nuestra Fuerza Pública para la defensa de los recursos naturales. Trabajando de forma articulada con la Fiscalía, el Ministerio de Medio Ambiente y Desarrollo Sostenible, el Instituto de Hidrología, Meteorología y Estudios Ambientales (Ideam), y la Unidad de Parques Nacionales Naturales, en diversas zonas del país, la Estrategia Artemisa ha permitido brindar apoyo a las autoridades ambientales y administrativas, para preservar y defender el agua, la biodiversidad y el medio ambiente en las áreas de reserva forestal, áreas protegidas y 59 Parques Nacionales Naturales. Mediante la Directiva Permanente 008 del 22 de marzo de 2022, el MDN institucionalizó e impartió lineamientos e instrucciones al Comando General de las Fueras Militares, la Dirección General de la Policía Nacional y la Unidad de Gestión General del MDN, con el propósito de implementar medidas, desplegar operaciones, actividades de apoyo y gestión ambiental, para la implementación de la Estrategia Artemisa. De esta forma y bajo un enfoque sostenido, conjunto, coordinado, interinstitucional y multilateral, se trabajará para incluir dentro de la doctrina militar y policial las acciones relacionadas con la protección del agua, la diversidad y el medio ambiente, al tiempo que se concentrarán los esfuerzos de inteligencia en la identificación del modus operandi de las organizaciones criminales que afectan el medio ambiente, desarrollando operaciones contra los GAO y los GDO que atentan contra el medio ambiente. Desde el 2019 a la fecha se han realizado diecisiete (17) operaciones sobre las áreas de los Parques Nacionales Naturales, especialmente en las regiones de la Amazonía y la Orinoquía, como son los Parques Nacionales Naturales (PNN) Serranía de Chiribiquete, PNN La Paya, PNN Tinigua, PNN Picachos, PNN Sierra de La Macarena, la Zona de Reserva Forestal de la Amazonía y la Reserva Natural Nukak. Se han dispuesto, para esta campaña, 22.300 hombres de la Fuerza Pública, que, desde sus respectivas unidades militares y policiales resguardan las áreas protegidas del territorio nacional. Estas unidades incluyen: 10 batallones de alta montaña (páramos), una brigada contra el narcotráfico, una brigada contra la minería ilegal, unidades de guardacostas, infantería de marina y efectivos de la Policía Nacional. El Sector Defensa es consciente de que a futuro será fundamental continuar fortaleciendo las capacidades de la Fuerza Pública para, en el marco de sus competencias, continuar apoyando a las autoridades ambientales, entes territoriales y a la comunidad en la defensa y preservación del agua, la biodiversidad y el medio ambiente como activos estratégicos de la Nación. Será fundamental profundizar la disrupción del delito de la explotación ilícita de minerales, mediante el desmantelamiento de las economías ilícitas que se lucran de ella y de la afectación de la cadena criminal. En igual medida, será vital apoyar la recuperación de los ecosistemas más afectados por las actividades ilegales, por medio de actividades de restauración de áreas, del trabajo articulado con las comunidades, la construcción y mantenimiento de viveros forestales y el fortalecimiento a las investigaciones científicas lideradas desde la Armada Nacional y la Dirección General Marítima para la protección de los océanos, el recurso hídrico y sus ecosistemas. De esta forma será posible continuar trabajando en la reducción de los riesgos que se ciernen sobre los ecosistemas del país y disminuir los índices de deforestación, y tras la búsqueda de soluciones que contribuyan a la reducción y mitigación de los GEI. Esta estrategia que ha puesto en marcha el Sector Defensa y que es recogido en esta obra, presenta los aportes sectoriales del trabajo interinstitucional que se han venido realizando en los últimos años, siendo un ejemplo de la forma en la que se pueden sumar esfuerzos para contribuir a la superación de la encrucijada global que nos afecta a todos y que debe ser enfrentada con un esfuerzo común.

Full textAbstract:
Macroeconomic summary Several factors contributed to an increase in projected inflation on the forecast horizon, keeping it above the target rate. These included inflation in December that surpassed expectations (5.62%), indexation to higher inflation rates for various baskets in the consumer price index (CPI), a significant real increase in the legal minimum wage, persistent external and domestic inflationary supply shocks, and heightened exchange rate pressures. The CPI for foods was affected by the persistence of external and domestic supply shocks and was the most significant contributor to unexpectedly high inflation in the fourth quarter. Price adjustments for fuels and certain utilities can explain the acceleration in inflation for regulated items, which was more significant than anticipated. Prices in the CPI for goods excluding food and regulated items also rose more than expected. This was partly due to a smaller effect on prices from the national government’s VAT-free day than anticipated by the technical staff and more persistent external pressures, including via peso depreciation. By contrast, the CPI for services excluding food and regulated items accelerated less than expected, partly reflecting strong competition in the communications sector. This was the only major CPI basket for which prices increased below the target inflation rate. The technical staff revised its inflation forecast upward in response to certain external shocks (prices, costs, and depreciation) and domestic shocks (e.g., on meat products) that were stronger and more persistent than anticipated in the previous report. Observed inflation and a real increase in the legal minimum wage also exceeded expectations, which would boost inflation by affecting price indexation, labor costs, and inflation expectations. The technical staff now expects year-end headline inflation of 4.3% in 2022 and 3.4% in 2023; core inflation is projected to be 4.5% and 3.6%, respectively. These forecasts consider the lapse of certain price relief measures associated with the COVID-19 health emergency, which would contribute to temporarily keeping inflation above the target on the forecast horizon. It is important to note that these estimates continue to contain a significant degree of uncertainty, mainly related to the development of external and domestic supply shocks and their ultimate effects on prices. Other contributing factors include high price volatility and measurement uncertainty related to the extension of Colombia’s health emergency and tax relief measures (such as the VAT-free days) associated with the Social Investment Law (Ley de Inversión Social). The as-yet uncertain magnitude of the effects of a recent real increase in the legal minimum wage (that was high by historical standards) and high observed and expected inflation, are additional factors weighing on the overall uncertainty of the estimates in this report. The size of excess productive capacity remaining in the economy and the degree to which it is closing are also uncertain, as the evolution of the pandemic continues to represent a significant forecast risk. margin, could be less dynamic than expected. And the normalization of monetary policy in the United States could come more quickly than projected in this report, which could negatively affect international financing costs. Finally, there remains a significant degree of uncertainty related to the duration of supply chocks and the degree to which macroeconomic and political conditions could negatively affect the recovery in investment. The technical staff revised its GDP growth projection for 2022 from 4.7% to 4.3% (Graph 1.3). This revision accounts for the likelihood that a larger portion of the recent positive dynamic in private consumption would be transitory than previously expected. This estimate also contemplates less dynamic investment behavior than forecast in the previous report amid less favorable financial conditions and a highly uncertain investment environment. Third-quarter GDP growth (12.9%), which was similar to projections from the October report, and the fourth-quarter growth forecast (8.7%) reflect a positive consumption trend, which has been revised upward. This dynamic has been driven by both public and private spending. Investment growth, meanwhile, has been weaker than forecast. Available fourth-quarter data suggest that consumption spending for the period would have exceeded estimates from October, thanks to three consecutive months that included VAT-free days, a relatively low COVID-19 caseload, and mobility indicators similar to their pre-pandemic levels. By contrast, the most recently available figures on new housing developments and machinery and equipment imports suggest that investment, while continuing to rise, is growing at a slower rate than anticipated in the previous report. The trade deficit is expected to have widened, as imports would have grown at a high level and outpaced exports. Given the above, the technical staff now expects fourth-quarter economic growth of 8.7%, with overall growth for 2021 of 9.9%. Several factors should continue to contribute to output recovery in 2022, though some of these may be less significant than previously forecast. International financial conditions are expected to be less favorable, though external demand should continue to recover and terms of trade continue to increase amid higher projected oil prices. Lower unemployment rates and subsequent positive effects on household income, despite increased inflation, would also boost output recovery, as would progress in the national vaccination campaign. The technical staff expects that the conditions that have favored recent high levels of consumption would be, in large part, transitory. Consumption spending is expected to grow at a slower rate in 2022. Gross fixed capital formation (GFCF) would continue to recover, approaching its pre-pandemic level, though at a slower rate than anticipated in the previous report. This would be due to lower observed GFCF levels and the potential impact of political and fiscal uncertainty. Meanwhile, the policy interest rate would be less expansionary as the process of monetary policy normalization continues. Given the above, growth in 2022 is forecast to decelerate to 4.3% (previously 4.7%). In 2023, that figure (3.1%) is projected to converge to levels closer to the potential growth rate. In this case, excess productive capacity would be expected to tighten at a similar rate as projected in the previous report. The trade deficit would tighten more than previously projected on the forecast horizon, due to expectations of an improved export dynamic and moderation in imports. The growth forecast for 2022 considers a low basis of comparison from the first half of 2021. However, there remain significant downside risks to this forecast. The current projection does not, for example, account for any additional effects on economic activity resulting from further waves of COVID-19. High private consumption levels, which have already surpassed pre-pandemic levels by a large margin, could be less dynamic than expected. And the normalization of monetary policy in the United States could come more quickly than projected in this report, which could negatively affect international financing costs. Finally, there remains a significant degree of uncertainty related to the duration of supply chocks and the degree to which macroeconomic and political conditions could negatively affect the recovery in investment. External demand for Colombian goods and services should continue to recover amid significant global inflation pressures, high oil prices, and less favorable international financial conditions than those estimated in October. Economic activity among Colombia’s major trade partners recovered in 2021 amid countries reopening and ample international liquidity. However, that growth has been somewhat restricted by global supply chain disruptions and new outbreaks of COVID-19. The technical staff has revised its growth forecast for Colombia’s main trade partners from 6.3% to 6.9% for 2021, and from 3.4% to 3.3% for 2022; trade partner economies are expected to grow 2.6% in 2023. Colombia’s annual terms of trade increased in 2021, largely on higher oil, coffee, and coal prices. This improvement came despite increased prices for goods and services imports. The expected oil price trajectory has been revised upward, partly to supply restrictions and lagging investment in the sector that would offset reduced growth forecasts in some major economies. Elevated freight and raw materials costs and supply chain disruptions continue to affect global goods production, and have led to increases in global prices. Coupled with the recovery in global demand, this has put upward pressure on external inflation. Several emerging market economies have continued to normalize monetary policy in this context. Meanwhile, in the United States, the Federal Reserve has anticipated an end to its asset buying program. U.S. inflation in December (7.0%) was again surprisingly high and market average inflation forecasts for 2022 have increased. The Fed is expected to increase its policy rate during the first quarter of 2022, with quarterly increases anticipated over the rest of the year. For its part, Colombia’s sovereign risk premium has increased and is forecast to remain on a higher path, to levels above the 15-year-average, on the forecast horizon. This would be partly due to the effects of a less expansionary monetary policy in the United States and the accumulation of macroeconomic imbalances in Colombia. Given the above, international financial conditions are projected to be less favorable than anticipated in the October report. The increase in Colombia’s external financing costs could be more significant if upward pressures on inflation in the United States persist and monetary policy is normalized more quickly than contemplated in this report. As detailed in Section 2.3, uncertainty surrounding international financial conditions continues to be unusually high. Along with other considerations, recent concerns over the potential effects of new COVID-19 variants, the persistence of global supply chain disruptions, energy crises in certain countries, growing geopolitical tensions, and a more significant deceleration in China are all factors underlying this uncertainty. The changing macroeconomic environment toward greater inflation and unanchoring risks on inflation expectations imply a reduction in the space available for monetary policy stimulus. Recovery in domestic demand and a reduction in excess productive capacity have come in line with the technical staff’s expectations from the October report. Some upside risks to inflation have materialized, while medium-term inflation expectations have increased and are above the 3% target. Monetary policy remains expansionary. Significant global inflationary pressures and the unexpected increase in the CPI in December point to more persistent effects from recent supply shocks. Core inflation is trending upward, but remains below the 3% target. Headline and core inflation projections have increased on the forecast horizon and are above the target rate through the end of 2023. Meanwhile, the expected dynamism of domestic demand would be in line with low levels of excess productive capacity. An accumulation of macroeconomic imbalances in Colombia and the increased likelihood of a faster normalization of monetary policy in the United States would put upward pressure on sovereign risk perceptions in a more persistent manner, with implications for the exchange rate and the natural rate of interest. Persistent disruptions to international supply chains, a high real increase in the legal minimum wage, and the indexation of various baskets in the CPI to higher inflation rates could affect price expectations and push inflation above the target more persistently. These factors suggest that the space to maintain monetary stimulus has continued to diminish, though monetary policy remains expansionary. 1.2 Monetary policy decision Banco de la República’s board of directors (BDBR) in its meetings in December 2021 and January 2022 voted to continue normalizing monetary policy.
