Academic literature on the topic 'Customary marine tenure'

Abstrak Sejak era otonomi daerah, setiap daerah memiliki kewenangan untuk mengelola dan memanfaatkan sumber daya di daerahnya, termasuk sumber daya kelautan dan perikanan. Adanya otonomi daerah juga berimplikasi pada peran serta masyarakat lokal sesuai dengan adat istiadat yang berlaku, termasuk hak ulayat laut yang dikelola adat (Customary Marine Tenure / CMT). Praktik-praktik CMT yang ada menunjukkan bahwa CMT dapat memberikan solusi terhadap masalah-masalah perikanan, termasuk mencegah munculnya tragedy of the commons yang mengakibatkan hilangnya spesies ikan. Di Kepulauan Maluku dan Papua, salah satu praktik CMT tersebut adalah hukum adat sasi laut yang berisi peraturan dan larangan dalam memanfaatkan sumber daya laut. Jika ditinjau lebih dalam, sasi laut dapat menjadi salah satu upaya tata kelola kelautan dan perikanan yang berbasis partisipasi masyarakat lokal dan memiliki prinsip berkelanjutan. Selain itu, pelaksanaan sasi laut juga membutuhkan dukungan dari pemerintah pusat dan pemerintah daerah agar keberadaannya dapat membawa manfaat bagi masyarakat, mendukung keberlanjutan sumber daya perikanan dan kelautan, dan menjaga keanekaragaman hayati. Kata kunci: sasi laut, hak ulayat laut, pengelolaan perikanan, pemerintahan daerah Abstract Since the era of regional autonomy, each region has the authority to manage and use the resources in its area, including marine and fisheries resources. The existence of regional autonomy also has implications for the participation of local communities in accordance with prevailing customs, including Customary Marine Tenure (CMT). CMT practices show that CMT can provide solutions to fisheries problems, including preventing the tragedy of the commons that could extinct fish species. In the Maluku Islands and Papua, one of the CMT practices is a customary law called marine sasi which contains rules and prohibitions in utilizing marine resources. Marine sasi is one of the efforts to regulate marine and aquaculture based on the participation of local communities and on the principles of sustainability. In addition, the implementation of marine sasi also requires support from the central government and local governments to be able to provide benefits to the community, support the sustainability of fisheries and marine resources, and support biodiversity.

This paper summarizes various integrated methodological approaches for studying Customary Management for the purpose of designing hybrid CM-Ecosystem-Based Management (EBM) systems in Oceania. Using marine conservation in the Western Solomon Islands as an example, the paper illustrates various interdisciplinary human ecological methods that can assist in designing hybrid conservation programs. The study of human-environmental interactions from a socio-ecological perspective allows us to discern people's understanding of their immediate environment, differential forms of local resource governance and use (e.g., sea tenure and foraging strategies), and existing conflicts between various stakeholders, among other social and ecological factors. More generally, the paper shows how coupled studies of natural and social processes can foster management regimes that are more adaptive and effective and that move toward holistic, ecosystem-based marine conservation in the Pacific Island region.

Purpose This study aims to unify phenomena in academic and grey literature into a theory of marine spatial disappropriation based on geopolitical relationships. It is argued that conflict over marine space arises as a result of top-down sovereign control of marine resources, and that the recognition of marine tenure and greater inclusivity in marine development* decision-making would lessen conflict between users, such as artisanal fishermen and ecotourism businesses. Design/methodology/approach A preliminary literature review was conducted, followed by a research study at Cabo Pulmo National Park (CPNP) in Baja California Sur, Mexico. Findings The results demonstrate that though CPNP's tenure structure is unique and inclusivity is an element of its management, the degree to which it is practiced is not sufficient to eliminate the chance of eventual disappropriation and ensuing conflict. Practical implications The results of this assessment can be used to strengthen the argument in favour of developing stronger requirements for deliberative democratic decision-making in marine delineation, as well as bolder social performance standards in marine development industries. Originality/value Research on socio-environmental revolutions are not new, but the authors contest that they are not alone a sufficient condition for achieving reduced conflict long-term. Instead, the originality of this research lies in its exploration of the importance of customary and formal tenure over marine resources, and its suggestion that this on the whole reduces conflict between exclusive and competing interests. One popular alternative, as demonstrated in numerous cases around the globe, can often be the marginalization of small-scale ocean users through the forceful appropriation of ocean resources.

The failure of centralised fisheries management systems to prevent the overexploitation of coral reef resources has led many scholars and conservation practitioners to promote the use of customary marine tenure (CMT) as an alternative devolved means of fisheries management. The effectiveness of CMT for fisheries management is debated; some scholars argue that CMT is embedded within particular historical, socio-economic and political contexts and that unless it evolves to changing circumstances, its effectiveness for fisheries management will wane under external influences and changing exploitation patterns. Each CMT regime is unique; hence its response to changing circumstances may vary. A better understanding of the circumstances under which a CMT regime is likely to succeed is important if it is to be effectively used for fisheries management. This research is posited on the DPSIR (Driver, Pressure, State, Impact, Response) model and employs multidisciplinary methods to investigate the effectiveness of CMT for reef finfish fisheries management. The aims of this thesis are: (1) To investigate the role of markets and subsistence as driving factors for fishing; (2) To investigate fisher spatial allocation of fishing, methods and target taxa (as proxies for pressure and impact); (3) contribute to the biological knowledge of a prominent vulnerable species (Plectropomus leopardus) by investigating aspects of its demography and reproduction (as a proxy for state); and (4) Investigate relationships between the Nggela CMT governance system and modern governance system (as a proxy for response), to improve understanding of how this knowledge may be applied to enhance small-scale fisheries management. The role of markets and subsistence as driving (D) factors for fishing was investigated using the sustainable livelihoods approach (SLA). Ninety three (43 from the western zone and 50 from the eastern zone) household surveys were conducted in 10 (5 from the eastern zone and 5 from the western zone) randomly selected villages in Nggela to determine the contribution of different livelihood activities to fisher livelihoods. The reason for comparing the eastern and western zone was to determine the role of available natural land capital as one contributing factor (besides markets) to fishing drivers. Quantitative data generated from the household surveys were analysed using the statistical package SPSS. Additional key informant interviews to generate qualitative data to support the quantitative data were also conducted. Spatial allocation of fishing and target taxa was investigated using household surveys (the same household survey mentioned above but with questions to address the issue of spatial allocation and fishing methods used), participative fishing with fishers to confirm spatial allocation of fishing and fishing methods employed and recording of landings data to determine the types of fish taxa targeted. One of the initial aims of studies on P. leopardus was to compare the age-based demographic parameters of P. leopardus between CMT areas and offshore sub-tidal areas, the hypothesis being that if CMT was effective agebased demographic parameters would reveal the non vulnerability of P. leopardus in CMT areas. Such a comparison was not possible as only 4 specimens were obtained from inshore CMT areas compared to 116 specimens from offshore sub-tidal reefs. To determine the age-based demographic parameters of Plectropomus leopardus, fish total lengths (mm) and otoliths of fish were collected in the field, this was followed by otolith annuli counts of ages (tagged to a particular fish of certain total length) at the laboratory. A von Bertalanffy growth curve was then fitted to the fish total length data and to the age data to determine asymptotic length, Brody growth coefficient and theoretical age at length zero. Total mortality rate was determined by generating catch curves where the frequency of fish in each age class was regressed against age. Longevity was determined by calculating the mean age of 10% of the oldest individuals. Demographic parameters of P. leopardus in Nggela were also compared to those of Australian locations to determine variations in age-based demography. Data analysis of P. leopardus data was done using the statistical software R and Microsoft Excel 2003. Reproductive aspects of P. leopardus were determined from the fish gonads collected from the field. Fish gonads were used to determine different sexual reproductive stages. Data on the different sexual reproductive stages was used to determine sexual maturity and sex change. The relationship between CMT governance and modern governance and how they may be combined for an effective reef finfish fisheries management was investigated using literature research, key informant interviews and dynamite fisher interviews. Investigations of livelihoods show that Nggela fishers were engaged in more than one livelihood activity for their livelihoods. Subsistence gardening was the most important livelihood activity. While finfish was important for subsistence purposes, accessible markets and the role of middlemen in the villages made it especially important for income generation. A comparison of the role of fishing between eastern and western zone showed that available natural land capital was also an important driver for fishing; fishing was higher in the western zone where there was a narrow natural land capital. Fisher perceptions indicate a declining trend in fisheries resource abundances within CMT areas; such decline has resulted in changes in the spatial allocation of fishing with a shift in fishing to offshore sub tidal reefs. Although some spatial closures were observed, fishing within the CMT areas is flexible. Three MPA’s currently existed in West Nggela and fishing prohibitions within the areas were observed mainly because people thought that the MPA’s were underscored by the government. Line fishing from dugout canoes remains the main method of fishing. Median trophic level of fish catch was between 2 - 3.84 while median standard length of catch was between 19 - 24 cm. Age-based demographic studies show that the Brody growth coefficient of Nggela P. leopardus was 0.13 yr-1, longevity was 12.9 years, maximum age was 15 years and mortality rate was 0.22% yr-1. Female sexual maturity of Nggela P. leopardus began at 2 years of age with 50% sexual maturity achieved at 3.22 years. Sexual transition from female to male began at 3 - 10 years of age with 50% sex change achieved at 11 years. Mature female to male ratio was 3:1. The age-based demographic parameters of P. leopardus in Nggela were similar to those in Swain and Lizard Island in Australia. For Swain reef, growth coefficient was 0.17 yr-1, longevity was 10.1 years, maximum age was 14 years and mortality rate was 0.39% yr-1. For Lizard Island, growth coefficient was 0.26 yr-1, longevity was 7.2 years, maximum age was 10 years and mortality rate was 0.59% yr-1. Age-based demographic parameters of P. leopardus in Nggela were different to locations in Western Australia – Scott and Abrolhos reefs. For Scott reef, growth coefficient was 0.42 yr-1, longevity was 6.4 years, mortality rate was 0.30% yr-1 while the maximum age was 8 years. For Abrohlos reef growth coefficient was 0.08 yr-1, longevity was 13 years, mortality rate was 0.24% yr-1 and maximum age was 18 years. Sea temperature may be one contributing factor to regional variations in age-based demographic parameters. The current CMT governance system has undergone changes which has rendered it ineffective as a coercive force for reef finfish fisheries management. While CMT is recognised by the modern governance system through National legislations, necessary ordinances at the provincial level are absent which prevent the effective use of CMT for fisheries management. For CMT to be effective it requires empowerment at the provincial government level.

In many ways, coastal marine resources have provided an important source of protein, income and even employment for coastal rural Solomon Islands communities. Fishing, for instance, has always played a very important role in these communities' culture and tradition. Subsistence fishing is traditional in most rural coastal communities. Small-scale fishing is also wide-spread. Traditionally marine areas and resources were managed by the custodians of the adjacent land and the traditional leaders in some local communities. While small-scale fisheries are managed by the Government, much of the enforcement responsibility is in the hands of the community leaders, given the realities of what that Government can provide. This research has explored the interaction between rural coastal livelihoods and marine resource management under Customary Marine Tenure (CMT) in one area of Temotu Province, Solomon Islands. Specifically the research seeks to explore, explain and describe how the livelihoods of the rural coastal villagers influence the use, access and management of marine resources and vice versa. Particular attention has been given to: first exploring the traditional marine resource management under CMT and livelihoods in the three villages; second, how the changes in the villagers' livelihoods system affects the customary marine resource management in the three case study villages; third, how changes in customary marine resource management influences the livelihoods of the villagers and finally the nature of the relationship between livelihoods and customary marine resource management is described for the first time for this part of the Solomon Islands. The research results showed that villagers' livelihoods have changed over the past decade and much of these changes have affected the customary marine resource management in the three case study villages. Consequently, customary marine resource management under CMT is no longer effective. The changes in customary marine resource also have implications on the villagers' livelihoods. For this reason the study argues that when trying to understand the factors affecting customary marine resource, the entire livelihoods system of the people should be considered. The study states that the nature of the interactions between livelihoods and customary marine resource management is a two-way relationship, dynamic and very complex. Should there be further marine resource development, the study suggests that understanding the livelihoods of the people concerned is important for better management.
