Abstract:

Extending Nepal's community forestry programme and its protected area network into lekh forests has been hampered by the assumption that people who live in or near lekh forests treat them as unregulated open access resources. This study tests this assumption by examining the interaction between local people and forests in two lekh areas of the central Middle Hills. The research is comprised of an action research approach, a theoretical framework of ecological anthropology that was also informed by forestry science, and tools and methods drawn from ethnographic fieldwork and rapid rural appraisal. The belief that lekh forests are treated as unregulated open access is challenged by demonstrating that there are clearly defined local use rights to lekh forests. Access to forest resources is regulated by forest users and relatively sophisticated and dynamic indigenous systems of forest management have been developed. The potential for implementing community forestry in the two lekh areas was explored by incorporating an element of action research in the study. A number of challenges are highlighted for the Nepal government to facilitate the improved management and conservation of lekh forests while ensuring an equitable flow of benefits to the people who depend on these forests.

Abstract:

This study characterizes the experience of five states that have chosen to pursue third party sustainable forest certification of publicly owned lands using the principles and criteria of the Forest Stewardship Council (FSC). Studying the impact of FSC certification on Minnesota, Wisconsin, Michigan, Ohio, and Pennsylvania may provide the Colorado State Forest Service and other forest stakeholders with an improved understanding of the potential impact of FSC certification of Colorado's public forests. This issue is especially pertinent to Colorado green builders who are attempting to acquire structural lumber from sustainably managed forests within a 500 mile (805 km) area of the construction site, as prescribed by US Green Build Council's (USGBC) Leadership in Environmental and Energy Design (LEED) standards. As there are no FSC certified forests in Colorado or neighboring states, sustainable builders cannot comply with some pertinent green building standards. Additionally, It is intended that this study will support sustainable forest policy studies and facilitate continuing research on the impact of FSC certification of Colorado public forests.

The Cabeça Gorda and Salvada forest is an area approximately 320 hectares of pine, oaks, eucalyptus, scrub, and grassland, under public administration and subject to partial forestry regime since 1960. In 2009 an agreement was signed between the National Forest Authority and the two owners, the parish councils of Cabeça Gorda and Salvada, in order to transfer management responsibility and administration from the first organization to the other two. This thesis is a contribution to establish a framework to multifunctional forest management of that area whose primary function is to protect water and soil and provide recreation conditions to the populations living in the surroundings. Some proposals are presented: lines of action considering the different functions of the forest such as protection, conservation, recreation, landscape service, production of wood and non-wood products as well as social and educational activities. Forest management systems certification requirements from Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC), have been tested as an exercise to characterize responsible (sustainable) forest management under the conditions of the Cabeça Gorda and Salvada forest. Several measures which are deemed essential to achieve sustainable forest management in the study area are presented.

Abstract:

The study is concerned with an examination of outdoor recreation at three forest recreation areas situated within and at the periphery of a large and major population region in Peninsular Malaysia. It was undertaken primarily to investigate the features that describe the use of these areas and to estimate the use-demand and quantification of consumers' surplus. Initially, a brief description of forest recreation in Peninsular Malaysia is presented. This is followed by a review of techniques for estimating consumers' surplus, after which it was concluded that an application of the travel cost method was appropriate for this study. An on-site questionnaire survey was used to gather a reasonable amount of user information. The questionnaire surveys carried out were found to be valuable; the information gathered facilitated the description and analysis of the areas' consumption, travel and use patterns and the behaviour of the users. Thus the surveys also provided information which was appropriate for the application of the travel cost technique. Subsequently, a detailed description of user behaviour is presented. Difficulties of the travel cost approach, were identified and addressed through the use of appropriate sample and extra-sample data. Particular attention was paid to the problems of multi-purpose trips, travel time bias and the influence of alternative sites on participation. Problems with functional forms and the weighting of points for the trip demand model were also given considerable attention. It is believed that the model selected in this study is an improvement on previously known models. The resulting estimates of consumers' surplus for the three areas are reasonably acceptable and conform to a priori expectations. Finally, the main conclusions of the thesis are highlighted and some aspects that have a bearing on planning and management issues are discussed along with brief recommendations for further and future research efforts.

Full text

Abstract:

Deforestation and land use change are widespread in western Uganda. However, the spatial patterns and time-series of change and the reasons why it is occurring remain to be fully investigated. In this work a combination of satellite imagery and social surveys is used to quantify forest gains and loss over the last three decades in the region close to Lake Albert, whilst also providing an account of possible drivers of change. This area proves to be interesting as it covers regions with both formally protected areas (gazetted regions) and un-protected forest, the latter being largely under private ownership. Remote sensing data from the Landsat satellites were gathered for forest change detection, and were processed using standard remote sensing techniques, then quantified using GIS and regression methods. Fieldwork allowed these data to be ground truthed while gathering (quantitative) household surveys and (qualitative) key informant interviews. Quantitative surveys were analysed using Principal Components Analysis (PCA) and cluster analysis, and were compared qualitatively with the satellite analysis and stakeholder interviews. The results show that forest cover declined significantly outside gazetted areas at the expense of varying local?scale processes, although the protection of the gazetted forests was remarkably successful. In forest corridors outside gazetted regions, losses exceeded 90% (p<0.05). Survey data suggest that rural poor households were more likely to be situated in forested regions, and were more dependent on forest resources for their livelihoods. However, the drivers of change were spatially variable, with expansion of sugarcane farming being a likely driver in the northern areas, but small?scale agricultural expansion a significant factor in the more southern parts of the study region. While there is wide agreement within the data that the patterns of forest cover and land use changes are anthropogenically driven, more specific drivers are swamped by intricacies of the bio-physical and socio-economic preconditions that are inseparable in both space and time, although agricultural expansion and population growth were evident and pervasive. The analyses provide insights into complex anthropogenic processes at various spatial scales, and policy recommendations provided are widely applicable for developing countries struggling to conserve nature whilst boosting economic growth.

Abstract:

In spite tropical forests are the most important terrestrial global carbon sinks due to carbon storage in aboveground biomass, it is also the primary target of deforestation. The conversion of Tropical forests into anthropogenic areas might disrupt biological flux and also lead to severe microclimatic changes at forest edges. These combined effects can trigger profound changes in plant composition through both high mortality of fragmentation-sensitive species and proliferation of disturbed-adapted species which will ultimately impacts carbon storage. Thus, our main objective in this study was understand the role of human-induced disturbances in modulate the dimension of biomass loss at tropical forests. We applied a systematic literature review searching for empirical evidences that edge effects can drive biomass loss in tropical forests (Chapter 2). Our findings highlighted the gap of knowledge about the pattern and process related to biomass loss in tropical forests. To strengthen this understanding, we formulated a conceptual model linking landscape structure and patch-level attributes to severity of edge effects affecting aboveground biomass. Our model hypothesizes that habitat amount, isolation, time since edge creation, and the synergism between edge distance, patch size, and matrix type are the main drivers of biomass loss in anthropogenic tropical forests. We thus used a large plant dataset (18 503 trees ≥ 10 cm dbh) from 146 sites distributed across four Mexican and four Brazilian rainforest regions to test our conceptual model predictions, specifically the influence of forest cover, site isolation, edge distance, patch size and type of matrix on biomass (Chapter 3). We observed that carbon-rich sites presented species that are typical of old-growth forests (shade-tolerant, large-seeded, zoocoric) contrasting to carbon-poor sites composed by disturbed-adapted species (pioneer occupying the understory). Large shade-tolerant trees (≥ 40 cm dbh) were impacted severely by the combination of forest loss and edge effects. Edge distance, patch size, and the amount of open-matrix strongly influence small shade-tolerant trees (≤ 20 cm dbh). Although our results do not fully corroborate the initial predictions of the conceptual model, they support the idea that landscape composition interact with patch structure and ultimately impacts biomass stocks in fragmented tropical forests. Finally, we further investigated if the disturbance level of the region influences plant-structure responses to forest loss (Chapter 4). Biomass, but not plant density, was affected by forest loss in regions with intermediate disturbance levels, i.e. regions showing a combination of moderate deforestation (20-40% of remaining forest cover) disturbed during the past 30-60 years, high defaunation but harboring relictual populations of large-mammals, and areas mostly composed by heterogeneous matrices. In general, our findings highlight that both landscape composition and patch structure are the main drivers of biomass loss in Neotropical forests, and that the landscape context must be considered to obtain more reliable estimations of carbon emissions due to forest degradation. Landscape planning (e.g. restoration of forest cover) should be included in conservation strategies in order to sustain carbon storage. Moreover, we advocate that conservation initiatives will be less costly and more effective if implemented in areas under intermediate disturbance levels
Apesar das florestas tropicais serem a mais importante fonte mundial de carbono da porção terrestre do globo devido ao armazenamento de carbono na biomassa acima do solo, elas são também o alvo primário do desmatamento. A conversão das florestas Tropicais em áreas antropogênicas pode interromper o fluxo biológico e também levar a severas mudanças microclimáticas na borda dos fragmentos. A combinação desses efeitos pode engatilhar profundas mudanças na composição da vegetação através tanto da mortalidade de espécies sensíveis à fragmentação como também pela proliferação de espécies adaptadas distúrbios, com impactos finais nos estoques de carbono. Assim, o maior objetivo desse estudo foi compreender o papel dos distúrbios induzidos pelo homem na modulação da dimensão da perda de biomassa em florestas Tropicais. Nós aplicamos uma revisão sistemática da literatura procurando por evidências empíricas de que o efeito de borda pode levar a perda de biomassa em florestas tropicais (Capítulo 2). Nossos resultados destacam a lacuna de conhecimento entre padrões e processos relacionados à perda de biomassa em florestas Tropicais. Para fortalecer esse conhecimento, nós formulamos um modelo conceitual conectando estrutura da paisagem e atributos na escala do fragmento à severidade do efeito de borda, e assim afetando a biomassa acima do solo. Nosso modelo hipotetiza que a quantidade de hábitat, o isolamento, o tempo desde a formação da borda e o sinergismo entre tamanho do fragmento, distância da borda e tipo de matriz são os principais condutores de perda de biomassa em florestas Tropicais antropogênicas. Utilizando um grande banco de dados (18 503 árvores ≥ 10 cm dap) provenientes de 146 locais distribuídos em quatro regiões de floresta úmida no México e quatro no Brasil, nós então testamos as predições do nosso modelo conceitual. Especificamente, a influência da cobertura florestal, isolamento, distância da borda, tamanho do fragmento e tipo de matriz sobre a biomassa (Capítulo 3). Nós observamos que áreas com muito carbono apresentaram espécies típicas de florestas maduras (tolerantes ao sombreamento, zoocóricas, com sementes grandes) contrastando com áreas com pouco carbono compostas por espécies adaptadas à distúrbio (pioneiras ocupando o sub-bosque). Árvores grandes tolerantes ao sombreamento (≥ 40 cm dap) foram impactadas severamente pela combinação de perda de cobertura florestal e efeitos de borda. Distância da borda, tamanho do fragmento e a extensão da área de matriz aberta influenciaram fortemente as árvores pequenas tolerantes a sombreamento (≤ 20 cm dap). Apesar dos nossos resultados não corroborarem completamente as predições iniciais do nosso modelo conceitual, eles dão suporte à ideia de que a composição da paisagem interage com a estrutura do fragmento com impactos finais nos estoques de biomassa em florestas Neotropicais. Por fim, nós investigamos se o nível de distúrbio da região pode influenciar nas respostas da estrutura da vegetação à perda de cobertura florestal. Biomassa, mas não a densidade de indivíduos, foi afetada pela perda de cobertura florestal em regiões com nível intermediário de distúrbio, i.e. regiões apresentando uma combinação de níveis moderados de desmatamento (20-40% de cobertura florestal remanescente) em que a perturbação ocorreu ao longo dos últimos 30-60 anos, com alto grau de defaunação mas ainda abrigando populações relictuais de grandes mamíferos e, em sua maioria, compostos por uma matriz heterogênea. Em geral, nossos resultados destacaram que tanto a composição da paisagem como a estrutura do fragmento são os principais condutores de perda de biomassa em florestas Neotropicais e que o contexto da paisagem deve ser considerado para se obter estimativas mais confiáveis de emissão de carbono devido à degradação florestal. O planejamento da paisagem (e.g. restauração da cobertura florestal) deve ser incluído em estratégias de conservação em ordem de sustentar o armazenamento de carbono. Além disso, nós defendemos que iniciativas de conservação serão menos custosas e mais efetivas se implementadas em áreas sob níveis intermediários de distúrbio

Abstract:

Tese de doutoramento em Economia, apresentada á Faculdade de Economia da Universidade de Coimbra , sob a orientação de Luís Cruz e Eduardo Barata.
National forests and woodlands are some of the environmental public resources that provide a diversity of goods and services to society. Supporting, regulating, provisioning and cultural services are all known to contribute to human well-being. As these services are not traded in regular markets because of the public or semi-public characteristics of the resources involved, their values are largely unknown. However, a deeper knowledge of the related benefits’ value is expected to help to enhance management practices. The research described in this dissertation concentrates on the analysis of the benefits related to recreational activities enjoyed in national forests and in understanding the demand for these environmental services. The research was motivated by the perception that these values are largely unknown, particularly in Portugal. Bussaco National Forest was chosen as the case study area, but the conclusions are likely to be adapted and extended to other national forests. Two non-market valuation techniques, the travel cost method and the contingent behaviour method, are used to estimate the recreational use benefits. The travel cost method, which belongs to the group of revealed preferences techniques, is used to analyse the actual behaviour and enables us to estimate recreational use values in current conditions. The individual version of the method is identified as the most accurate in the present context as we analyse the recreational demand of a forest visited by people living at different distances from it. From the management perspective, it is also important to address how people would behave if new hypothetical conditions were to be observed. It is particularly important to predict the effects on demand resulting from changes in forest access costs and from the deterioration of current conservation conditions due to a forest fire. The contingent behaviour method, which belongs to the group of stated preferences techniques, is applied jointly with the travel cost method to assess the effects of these changes. Count data models corrected for endogenous stratification and ordered models are used in the analysis of the actual visit behaviour. Travel cost, substitute cost, income per capita, visit motivations, on-site time and visit distribution during the year were identified as the main explanatory variables of demand. Price and income elasticity of demand computed using count data models are low. This result is supported by the ordered models, as results show that the change in income/price must be quite significant to modify demand levels. Considering only the current users, the forest recreational use value estimated for the past three years is about €106 700. A count data model and a pseudo-panel specification is used to combine contingent and observed travel behaviour. The analysis reveals that visitors are sensitive to price and quality changes and that in the forest fire scenario the intended number of trips would be seriously reduced, thus imposing an important welfare loss. There are evidences of hypothetical bias in answers to future behaviour if current conditions do not change and signals of strategic bias when changes in management options are in view. There are no signals of these biases when the quality changes are exogenous.

Abstract:

Bayesian estimates of gross cubic- foot volume per acre were computed for four stand types (plantation pine, natural pine. hardwood. and mixed wood stands) using aerial photo volume tables as the prior information source. Aerial photographs provided a reliable source of information even though most photographs were nearly five years old. For a given level of precision within a particular stand, Bayesian methods reduced the required field sample size up to 50% using all or half of the prior information available. Those priors which utilized a regression or a regression/topographic correction in the estimation of photo heights required less field information for the given precision level than those priors which used uncorrected or topographic corrected photo heights. In order to obtain meaningful gains in sample size reduction corrections to the estimated photo heights should be made. Although the uncorrected prior produced generally less biased estimates. the reduction in sample size was not as large as that observed using other prior types. Greater gains were attributed to the better accuracy of the prior distribution. Although Bayesian methods are biased, it appeared that these methods tempered severely biased prior distributions. In the hardwood stand for example, the average bias present in the photo volume data amounted to -140%. After combining the prior with the field sample, the greatest average bias was -50%. Bayesian methods performed better than the traditional estimation methods in terms of precision. In a one to one comparison. the Bayes standard error was consistently less than its non-Bayes counterpart. The one exception to this trend was the regression prior from the hardwood stand. The poor performance of the prior was due to the weak height regression correction equation. Modal priors utilized were not subject to the extreme input values for prior distribution development as their conservative empirical prior counterparts were. Less overall variation was observed 1n the estimated values. Under the conditions for mode selection set forth in this project, modal priors provided another good source of prior information.

Abstract:

The enterprise Derome Forest, which manages the supply of raw materials to Derome Group's industries, wants to develop its communications with suppliers and also the forest services that the company provides. The purpose of the study was to find new information channels for forest companies to communicate about forest services to existing and future suppliers. In order to answer the research questions and achieve the purpose of the study, a questionnaire was chosen as a method in combination with a focus group. The most sought after services were final felling, thinning, and pre commercial thinning and planting. Forestry magazines, personal meetings and social activities were important sources of knowledge for forest owners. Few of the forest owners replied that they used the websites of forest companies or followed them on social media, although most of the respondents estimated that their internet use for forest purposes will increase. Digital calendars with forest companies' activities and mobile apps for measuring and calculating were digital tools that were requested. Damage and diseases on forests, intrusion issues and thinning were subjects that many forest owners thought was difficult. Greater diversity in forestry methods and a more goal-based and diversified advice were requested from forest companies.

Abstract:

The subtropical forest biome accounts for approximately a quarter of the area of China and is particularly important for local economies, and for maintaining biodiversity and the carbon balance of forest ecosystems. Despite their importance, there is still considerable uncertainty about the characterization and spatial distribution of tree species, as well as the carbon budgets of these forests, many of which have been altered by anthropogenic activities. Remote sensing has the potential to provide quantitative, spatially explicit information for mapping and monitoring forest ecosystems. It is also a cost-effective tool to provide temporally uniform and “wall-to-wall” observations over time. Light Detection and Ranging (LiDAR) is an active remote sensing laser technology that provides an advantage over most other remote sensing technologies in its ability to provide detailed three-dimensional information of forest canopy structure, which is particularly useful for studying forest biophysical and structural properties. The aim of this dissertation is to investigate novel approaches for using and examining the effectiveness of LiDAR technologies, in order to classify tree species and estimate forest biomass and dynamics, across a study site within the subtropical region of southeast China. Specifically, airborne LiDAR was evaluated for its ability to: (i) discriminate tree species using small-footprint full-waveform LiDAR metrics; (ii) estimate forest biomass components by discrete-return and full-waveform LiDAR metrics; (iii) spatially extrapolate the estimation of forest biomass components, and (iv) predict and map biomass dynamics using multi-temporal LiDAR data. The results of this dissertation confirm that LiDAR-based approaches can make significant contributions to analyze the structure, composition and distribution of tree species across the study site, and provide effective methodologies and techniques for developing high resolution, spatially explicit estimations of forest biomass (and its dynamics). These methods have important applications to sustainable forest management, forest carbon cycling studies and carbon accounting projects.

Abstract:

This thesis is concerned with the changes to a forest landscape, that of St. Leonard's Forest, Horsham, West Sussex, changes that were wrought by human activity over two and half centuries. In order to uncover and understand these changes the author has focused on five private estates within the Forest core, Holmbush, Buchan Hill, St. Leonard's, Coolhurst and Leonardslee, and two villages in the Forest, Colgate and Lower Beeding. The five estates are considered with regard to ownership and control, land use and workers on the estates. The two villages are examined for their growth, the profile of the population, poverty and wealth. The establishment and endowments of the parish churches are outlined along with the development of the parish of Lower Beeding and its ties to Magdalen College, Oxford. Paternalism was a theme in the Victorian and Edwardian period, and the 1900 Footpath Dispute demonstrated a move away from these attitudes towards a more individualistic concern with private property rights. For the first time this study pulls together the numerous and complex strands which make up the landscape history of St. Leonard's Forest. It explores the factors both social and economic which impacted on the Forest. The juxtaposition of the nearby expanding market town of Horsham with its large common, improving communications, sales of land, and the attitudes of individual Forest landowners all combined to transform the Forest from a wild barren heathland in 1750 to a place of desirable picturesque estates and expanding villages by 1914, before the impact of the Great War was to change the Forest landscape yet again.

ENGLISH ABSTRACT: A case study in miombo woodlands was carried out in Pindanganga and MOFLOR forest concession, Gondola and Dondo Districts respectively, in the centre of Mozambique, to analyse the impact of alternative forest management regimes and sectoral and extra sectoral policies on the well being of stakeholders and conservation of the woodlands. A system dynamics model, MIOMBOSIM, based on game theory and implemented in POWERSIM was developed. The analysis is based on a simulation model of the fluctuation over time of the human population, forest dynamics, harvesting costs of the private sector, household consumption, commercial outputs and prices (timber, charcoal, non timber forest products and domestic animals), using data from field surveys and the literature. It also simulated the effects over time of changes in charcoal production efficiency, sales amount and marketing prices of NTFPs, agricultural output prices, off-miombo greater employment availability and a combination between the changes (simultaneous increase in marketing prices ofNTFPs and agricultural output prices, simultaneous increase in charcoal production efficiency and agricultural output prices, and simultaneous increase in off-miombo greater employment availability and agricultural output prices). The modelling approach chosen allows to evaluate management regimes taking into account the different stakeholder interests, which are often conflicting. This study shows that improvement in the well being of stakeholders and resource conservation can be achieved with sound forest management practices. There is no management regime capable of fully satisfying the goals of the stakeholders. The cooperative management option is potentially beneficial to local communities if properly implemented and can improve the rural livelihoods and the woodland resources condition. It also shows that regulated forest management regimes incorporating social concerns or incorporating social and environmental concerns are potentially more beneficial to the household sector than the open access regime. Results found in the study show that an increase by 10% and 30% on charcoal production efficiency can lead to an increase in the per capita benefits of the household sector by 3.0 to more than 100%, but can not reach the poverty line (one dollar per day per person). An increase by 100% in the sales amount or 100% increase in market selling prices of NTFPs can lead to an increase in the per capita benefits of the household sector. An increase in agricultural output selling prices by 25% without any other incentive leads to agricultural expansion. An increase by 100% in off-miembo employment opportunities in the study areas has an insignificant impact on resource use and conservation for the local communities due to the very low employment opportunities currently in place (0.008% in Pindanganga and 0.005% in MOFLOR area). A combination of these two policies instruments under ceteris paribus condition can improve the well being of the rural communities depending on the management regime option, but can not reach the poverty line (one dollar per day per person). The ranking of the management regime can change depending on the policy instrument applied.
AFRIKAANSE OPSOMMING: 'n Gevalle-studie is in Miombo boomveld in Pindanganga en MOFLOR, onderskeidelik in die Gondola en Dondo Distrikte in die sentrale deel van Mosambiek, uitgevoer om die impak van alternatiewe bosbestuursisteme en sektorale en ekstra-sektorale beleide op die welstand van belanghebbendes (stakeholders) en bewaring van die boomveld te ontleed. 'n Sisteem-dinamika model, MIOMBOSIM, gebaseer op spel teorie (game theory) en ge-implementeer in POWERSIM, was ontwikkel. Die analise is gebaseer op 'n simulasie-model van die fluktuasie oor tyd van die plaaslike bevolking, bosdinamika, oestingskostes van die private sektor, huishoudelike verbruik, kommersiële uitsette en pryse (hout, houtskool, nie-hout produkte en huishoudelike diere), deur data van veldopnames en uit die literatuur te gebruik. Die invloede oor tyd in veranderinge in effektiwiteit van houtskoolproduksie, verkoopsvlakke en markpryse van nie-hout produkte, landbou uitsetpryse, beskikbare indiensneming buite die Miombo boomveldgebiede, en 'n kombinasie tussen die veranderinge, is ook gesimuleer. Die gekose modelleringsbenadering het dit moontlik gemaak om die bosbestuursisteme te evalueer met inagneming van die verskillende en dikwels teenstrydige behoeftes van die belanghebbendes. Die studie het getoon dat verbetering In die welstand van die belanghebbendes en hulpbronbewaring bereik kan word met gesonde bosbestuurspraktyke. Geeneen van die bosbestuursisteme kan die doelwitte van die belanghebbendes ten volle bevredig nie. Die kooperatiewe bestuursopsie is potensieel voordelig vir die plaaslike gemeeskappe indien behoorlik ge-implementeer, en kan die landelike lewensbestaan sowel as die toestand van die boomveld as hulpbron verbeter. Gereguleerde bosbestuursisteme wat sosiale belange of sosialeomgewingsbelange insluit, is potensieel meer voordelig vir die huishoudelike sektor as die vrye toegangsisteem (open access regime). Resultate van die studie het getoon dat 'n toename van onderskeidelik 10% and 30% in effektiwiteit van houtskoolproduksie kan lei tot 'n toename in per kapita voordele van die huishoudelike sektor van 3.0% tot meer as 100%, maar kan nie lei tot 'n vebetering bokant die armoedevlak nie (een VSA doller per dag per persoon). 'n Toename van 100% in die hoeveelheid verkope of 'n 100% toename in die markverkoopsprys van nie-hout produkte kan lei tot 'n toename in die per kapita voordele van die huishoudelike sektor. 'n Toename in die landbou uitsetverkoopspryse met 25% sonder enige ander insentiewe lei tot landbou-uitbreiding. 'n 100% Toename in indiensnemingsgeleenthede buite die Miombo boomveldgebiede in die studiegebiede het onbeduidende impakte op hulpbrongebruik en bewaring vir die plaaslike gemeenskappe as gevolg van baie lae huidige indiensnemingsgeleenthede (0.008% in Pindanganga en 0.005% in MOFLOR). 'n Kombinasie van die twee beleidsinstrumente onder toestande van ceteris paribus kan die welstand van die landelike gemeenskappe verbeter afhangende van die bestuursisteemopsie, maar kan nie die armoedsvlak oorskry nie (een VSA doller per dag per persoon). Die rangorde van die bestuursisteem kan verander afhangende van watter beleidsinstrument toegepas word.

Abstract:

Experiments show that forest net primary productivity (NPP) increases as atmospheric [CO2] increases. The aim of this thesis is to use process-based models to analyse the mechanisms underlying this response to atmospheric [CO2]. I used two models named MAESTRA, which is a complex model of canopy photosynthesis and MATE, a simpler model of forest carbon and water balance that is useful for long-term simulations. These models are applied to a Free-Air CO2 Enrichment (FACE) experiment on a sweetgum plantation at Oak Ridge, Tennessee, USA. In this experiment, trees growing at elevated CO2 (eCO2, 550 ppm) have a higher net primary production (NPP) than trees at ambient CO2 (aCO2, 375 ppm). The aim of my research is to understand the reasons for differences in production at aCO2 and eCO2 rings. Simulations of both models are analysed to determine whether differences between NPP at aCO2 and eCO2 are the result of changes in light use efficiency (LUE) or absorbed photosynthetically-active radiation (APAR). A second question is whether the models can explain inter-year variation in NPP. The model focuses on a two-year period, 1999-2000 when extensive data are available on NPP, photosynthesis, leaf area index (LAI), and tree transpiration. Using MAESTRA I found that: 1. Because LAI was not affected by eCO2, simulated APAR is insensitive to eCO2. Therefore enhanced total canopy photosynthesis at eCO2 is caused by increased LUE. 2. Jmax and Vcmax were slightly higher at aCO2 than in eCO2 (except for May and September 1999), indicating that photosynthesis was not down-regulated at eCO2. Values of LUE were higher in 2000 compared with 1999 at both aCO2 and eCO2. LUE was higher on days when incident PAR (IPAR) was low. 3. APAR was reduced from 1999 to 2000 due to changes in IPAR and LAI. The counter-action between reduced APAR and increased LUE cancelled each other so that NPP simulated by MAESTRA did not differ greatly from 1999 to 2000. This was in contrast with NPP data, which showed considerably higher values in 2000 than in 1999. 4. Modelled transpiration agreed well with sapflux data in mid-season at both aCO2 and eCO2 but transpiration was underestimated at start and end of year. 5. The response of simulated NPP to eCO2 was 18 and 15% in 1999 and 2000, respectively. These results compare with measured NPP responses to eCO2 of 16 and 27%, respectively. Using MATE model I found that: 1. Simulated APAR is insensitive to eCO2, thus increased GPP at eCO2 was associated with enhanced LUE rather than enhanced APAR. 2. Simulated GPP in 2000 was higher than in 1999 due to increased LUE in 2000, despite reduced annual APAR. 3. Modelled transpiration agreed well with sapflux data at aCO2 in mid-season but underestimated transpiration at eCO2. The model underestimated transpiration at start and end of the year. 4. Simulations of plant available water showed wetter soils at eCO2. 5. Modelled NPP showed less response to eCO2 in 1999 (6% increase) than in 2000 (12% increase). These CO2 responses compare with measured NPP increases of 16 and 27% in 1999 and 2000, respectively.

ENGLISH ABSTRACT: Nyungwe Forest in the South West of Rwanda is surrounded by a dense human population (350 people/km') which depends on subsistence agriculture and livestock. Previous reports on the Forest have shown that its survival is threatened by illegal use of its resources. Participatory rural appraisal was conducted in five Communes next to the Forest to study the community's perceptions, uses and interests with respect to access and management of the Forest. Respondents perceived the Forest as a source of 18 categories of products of which only 14 were said to be of value for the respondents'livelihoods. Land, timber and minerals (gold) were the priority resources preferred by more than 55% of the respondents. Other important resources included fodder/pastures, wooden goods, fuelwood and poles. Fourteen different species were most preferred for timber, 16 for poles, 45 for medicinal materials and six for wooden goods. However, the majority of these species were preferred for multiple uses as timber, poles and medicines. A forest resource assessment was carried out to identify the stock of the preferred tree species. Not all woody resources mentioned as being preferred were available, with some tree species not found at all in the Forest. In order to identify tree species that can be used sustainably, different criteria including abundance (density), dominance, diameter size-class distribution and regeneration, were used in combination. Of the 12 tree species recorded in the Forest and most preferred for timber, only three species were present in sufficient abundance and sizes to allow sustainable utilisation. Of the 12 pole species identified, six were not vulnerable to exploitation, and of the preferred medicinal tree species only five were considered to fit into this category. Low resource availability and the need to address the interests of adjacent communities necessitated management options which enable access to some resources and benefits the communities as well as conservation measures to protect the biodiversity. A range of joint forest management options is discussed in order to assess the feasibility of a collaborative approach in the management of Nyungwe Forest. Some recommendations are made with respect to access to resources, the use of substitutes and areas for future research.
AFRIKAANSE OPSOMMING: Nyungwe Bos in die suidweste van Rwanda word omring deur 'n digte bevolking van 350 mense/km- wat van bestaanslandbou en lewende hawe afhanklik is. Vorige verslae het aangedui dat die voortbestaan van die Bos bedreig word deur die onwettige gebruik van sy hulpbronne. 'n Evaluering is in vyf gemeenskappe (Communes) langs die Bos gedoen om die gemeenskap se persepsies oor, gebruike van en belangstelling in die toegang tot die Bos, sowel as die bestuur daarvan te bestudeer. Die mense van hierdie plattelandse gebied is by die evaluering betrek. Respondente sien die Bos as 'n bron van produkte wat in 18 kategorieë ingedeel kan word, maar waarvan slegs 14 kategorieë van waarde is vir die respondente om 'n bestaan te kan maak. Meer as 55% van die respondente het grond, hout en minerale (goud) as die belangrikste hulpbronne aangedui. Ander belangrike hulpbronne sluit in veevoer of weivelde, houtartikels, brandhout en pale. Die respondente het 14 verskillende houtspesies verkies as timmerhout, 16 vir pale, 45 vir medisinale gebruike, en ses vir houtartikels. Die meerderheid van hierdie spesies is egter verkies vir veelvuldige gebruike soos timmerhout, pale en medisyne. 'n Evaluering van die hulpbronne in die bos is uitgevoer om te bepaal hoeveel bome van die gunstelingspesies daar in die bos is. Nie al die houthulpbronne wat deur die respondente verkies is, was beskikbaar nie, en sommige boomspesies is glad nie in die Bos gevind nie. Ten einde boomspesies te identifiseer wat vir lewensmiddele gebuik kan word, is 'n kombinasie van verskillende kriteria gebruik, insluitende die hoeveelheid bome (digtheid), dominansie, die verspreiding van die verskillende klasse deursneegroottes, en regenerasie. Van die 12 boomspesies in die Bos wat na aanleiding van hierdie evaluering opgeteken is en wat voorheen as gunstelingspesies vir timmerhout aangedui is, is daar slegs drie wat volop en groot genoeg is om vir lewensmiddele gebruik te word. Van die 12 spesies wat vir pale geïdentifiseer is, is ses teen oorontginning bestand, en van die gunsteling medisinale boomspesies val slegs vyf in laasgenoemde kategorie. Lae hulpbronbeskikbaarheid en die behoefte om die aangrensende gemeenskappe se belange aan te spreek, het bestuuropsies genoodsaak wat toegang tot sommige hulpbronne moontlik maak en wat die gemeenskappe bevoordeel, sowel as bewaringsmaatreëls ten einde die biodiversiteit te beskerm. 'n Verskeidenheid gesamentlike bosbestuuropsies is bespreek ten einde die uitvoerbaarheid van 'n benadering van samewerking in die bestuur van die Nyungwe Bos te ondersoek. Enkele aanbevelings is gemaak wat betref toegang tot hulpbronne, die gebruik van plaasvervangers, en studiegebiede vir verdere navorsing.

Abstract:

Management, under the concepts of multiple-use and adaptive management, requires the assessment of potentials and limitations of the natural ecosystems to provide satisfaction to human needs, to protect long term productivity, and preserve biological diversity. Overstory-understory relationships were developed for ponderosa pine (Pinus ponderosa) ecosystems to help managers to evaluate herbage production potentials. Secondary data sources from the Beaver Creek and the Heber Watersheds were divided as follows: igneous soils, igneous clay loam, igneous loam-sandy loam, sedimentary soils, alluvium, and sandstone. Regression models were fitted to the raw data by the least squared method. The dependent variables were herbage production (lb/ac) by component; namely total, grass and grass like plants, forbs and half shrubs, and shrubs. The independent variables were total and ponderosa pine basal area (ft 2 /ac). Semilogarithmic models fitted the data from igneous soils, while logarithmic transformations of hyperbolic models fitted the data from sedimentary soils. For igneous soils, ponderosa pine basal area suffice for adequate predictions of herbage production. Significant differences were found between equations for alluvium and sandstone. The resulting equations for ponderosa pine integrate the core of the model UNDER. Mathematical functions developed elsewhere are included in UNDER to compute herbage production in pinyon-juniper and mixed conifer ecosystems. UNDER is linked to other simulators by MICROSIM. MICROSIM, a multiple-resource simulation model, is a tool to assist in the assessment of potentials of forest and woodlands of Arizona. MICROSIM is a menu driven program for IBM or compatibles it contains the module Flora, for estimating plant responses, and module Fauna, to evaluate impacts on animals. Further development of MICROSIM should include the linkage to more modules and models, and to Geographical Information Systems.

Abstract:

The Río Pláttano Biosphere Reserve, a tropical rainforest reserve in the northeastern corner of Honduras, is home to several subsistence-based indigenous groups, including the Miskito, Pech and Garifuna, as well as the non-indigenous Ladinos. Communities within the reserve depend on forest resources, swidden agriculture, marine resources and/or small-scale ranching as the foundations for local economies. Regulations placed on these subsistence practices, after establishment of the biosphere reserve in 1980, have created unique and new pressures and resulted in a blend of traditional and innovative resource use. A notable result is the promotion of ecotourism as a solution for meeting the economic needs of local populations while conserving local resources. This thesis documents current resource use in the Miskito and Ladino communities of Banaka, Brans, and Fuente de Jacob, in the Río Pláttano Biosphere Reserve and the potential of ecotourism to maintain both local economies and consumption of tropical rainforest resources in these communities. Analysis suggests that a community-based approach to ecotourism can result in economic benefits and maintain local culture. This thesis documents current resource use (agricultural crops and trees, gathered and cultivated plants, tree-use, and hunting), resident perspectives on ecotourism development and industry, and provides the foundation for long-term monitoring and analysis on the effects of ecotomism on forest resource and land-use in the greater Banaka region.

Abstract:

A major environmental concern throughout the tropics is deforestation. While many forests are in a state of crisis, such an encompassing narrative can obscure significant instances where forest-cover expands. This research investigates the geography of forest regeneration in rural Costa Rica from a social and institutional perspective. Attracted to the Pacific coast, foreigners purchase farms, change the patterns of land ownership, and extensively promote secondary forest growth. Environmental change and a declining agriculture sector have forced peasants to sell or abandon land and diversify their livelihoods. Two conservation NGOs collaborate at an institutional level to promote reforestation and consolidate protected properties into the Mesoamerican Biological Corridor. Drawing on foreign funding, they serve as an avenue through which external visions of land management become reproduced locally. This case illustrates how the values and management decisions of a constellation of actors synergistically interlink to influence local land-use and ultimately join to expand forest-cover.

Abstract:

The forest sector is traditionally viewed as stagnant and non-innovative in comparison to higher-value added industries. The sector is being challenged by environmental, market and consumer changes at home and internationally. To combat these challenges, forestry firms must undergo a transformation in their activities, including their production methods by producing innovative and sustainable products and materials. This involves investing in innovation, advanced technologies and new products. The purpose of this study is to understand the impact of adoption of advanced manufacturing technologies on firm performance in the Canadian forest sector. The study is based on data from the 2007 Survey of Advanced Technology and interviews with technology adopters. The differences between technology adopters and non-adopters in terms of capital investment, R&D, training, management practices and innovation were analyzed. The findings suggest that the adoption of advanced technologies is important for the realizations of innovations. Firms which were both innovative and adopted technology were most likely to report improvements in performance post-adoption.
