This thesis employs a network perspective in studying ecosystems and natural resource management. It explores the structural characteristics of social and/or ecological networks and their implications on societies’ and ecosystems’ ability to adapt to change and to cope with disturbances while still maintaining essential functions and structures (i.e. resilience). Paper I introduces terminology from the network sciences and puts these into the context of ecology and natural resource management. Paper II and III focus on habitat fragmentation and how it affects an agricultural landscape in southern Madagascar. Two ecosystem services were addressed: (1) crop pollination by bees, and (2) seed dispersal by ring-tailed lemurs. It is shown that the fraction of the studied landscape presently covered by both crop pollination and seed dispersal is surprisingly high, but that further removal of the smallest habitat patches in the study area could have a severe negative impact on the landscape’s capacity to support these ecosystem services. In Papers IV and V, the network approach is used to study social networks and the impact they may have on the management of natural resources. In Paper IV it is found that social networks of low- to moderate link densities (among managers) significantly increase the probability for relatively high and stable utility returns whereas high link densities cause occasional large-scale ecological crises between periods of stable and excessively high utility returns. In Paper V, social networks of a rural fishing community in eastern Africa were analyzed. The results indicate that patterns of communication partly explain the distribution of ecological knowledge among villagers, and that gear type used by small-scale coastal fishermen strongly correlates with their patterns of communication. The results also show that groups most central in the network, and hence potentially most influential, are dominated by one type of fishermen.

The present study is one of the first attempts to analyze the societal importance of seagrasses (marine flowering plants) from a Natural Resource Management perspective, using a social-ecological systems (SES) approach. The interdisciplinary study takes place in East Africa (Western Indian Ocean, WIO) and includes in-depth studies in Chwaka Bay, Zanzibar, Tanzania. Natural and social sciences methods were used. The results are presented in six articles, showing that seagrass ecosystems are rich in seagrass species (13) and form an important part of the SES within the tropical seascape of the WIO. Seagrasses provide livelihoods opportunities and basic animal protein, in from of seagrass associated fish e.g. Siganidae and Scaridae. Research, management and education initiatives are, however, nearly non-existent. In Chwaka Bay, the goods and ecosystem services associated with the meadows and also appreciated by locals were fishing and collection grounds as well as substrate for seaweed cultivation. Seagrasses are used as medicines and fertilizers and associated with different beliefs and values. Dema (basket trap) fishery showed clear links to seagrass beds and provided the highest gross income per capita of all economic activities. All showing that the meadows provide social-ecological resilience. Drag-net fishery seems to damage the meadows. Two ecological studies show that artisanal seaweed farming of red algae, mainly done by women and pictured as sustainable in the WIO, has a thinning effect on seagrass beds, reduces associated macrofauna, affects sediments, changes fish catch composition and reduces diversity. Furthermore, it has a negative effect on i.a. women’s health. The two last papers are institutional analyses of the human-seagrass relationship. A broad approach was used to analyze regulative, normative and cultural-cognitive institutions. Cooperation and conflict take place between different institutions, interacting with their slow or fast moving characteristics, and are thus fundamental in directing the system into sustainable/unsustainable paths. Ecological knowledge was heterogeneous and situated. Due to the abundance of resources and high internal control, the SES seems to be entangled in a rigidity trap with the risk of falling into a poverty trap. Regulations were found insufficient to understand SES dynamics. “Well” designed organizational structures for management were found insufficient for “good” institutional performance. The dynamics between individuals embedded in different social and cultural structures showed to be crucial. Bwana Dikos, monitoring officials, placed in villages or landing sites in Zanzibar experienced four dilemmas – kinship, loyalty, poverty and control – which decrease efficiency and affect resilience. Mismatches between institutions themselves, and between institutions and cognitive capacities were identified. Some important practical implications are the need to include seagrass meadows in management and educational plans, addressing a seascape perspective, livelihood diversification, subsistence value, impacts, social-ecological resilience, and a broad institutional approach.

This thesis is concerned with the efforts to bring about a greater degree of local community participation in the use and management of Sri Lanka's coastal land and natural resources. Through the application of the Special Area Management (SAM) strategy in geographically distinct areas along the coast, the aim is to create collaborative arrangements - partnerships - that will enable coastal communities and local governments to work together with the Sri Lankan state and share responsibility and authority over the management of coastal land and natural resources. Using a political-geographical perspective that highlights the political and spatial dimensions of this shift in forms for governing the coast, the thesis seeks to identify and discuss factors that can have a bearing on the participatory dimension of collaborative coastal management in Sri Lanka. The thesis focuses particularly on factors influencing the role played by the local communities and the degree to which they actually come to share authority with respect to the use and management of coastal natural resources as envisioned in the SAM strategy. The thesis illustrates that, despite an ambition to bring about a sharing of authority and control in costal management, this has not quite worked out in practice. Due to circumstances relating both to the SAM strategy itself and to the context in which it is implemented, the degree to which coastal communities have gained any degree of influence with respect to the management of coastal land and resources remains questionable. The study is carried out prior to the tsunami that hit the Sri Lankan shores in December 2004. However, given the major reconstruction of Sri Lanka's coast that currently is ongoing and the controversy that surrounds it, the issues raised in this thesis are highly relevant.

<p>In most developing countries, forest resources are a major source of livelihood for forest dwellers. Forests provide fuel wood, farm products, meat, timber and plants of high medicinal value, including Prunus africana. The collection of medicinal plants is also an important source of cash income for some forest communities, and widely relied on to cure illnesses (Poffenberger, 1993). Because of this, the poor forest dwellers in particular are forced to exert pressure on their surrounding environment to make ends meet. Indiscriminate exploitation of forest resources has cost some forest dwellers dearly as they are now experiencing marked reduction of wildlife, forest cover, soil fertility and most importantly water supply, which is a key to life. Prunus africana has a very high economic and medicinal value locally as well as internationally. The exploitation of this species is a very profitable activity in most parts of Africa where it occurs, including the Mount Cameroon region. In recent years, most youths and young men in the Mount Cameroon region have seemingly become less interested in their usual income generating activities (farming, hunting, etc.) because of reduced productivity and have taken up Prunus harvesting as their major source of income. Increase in demand for this species by the French pharmaceutical company (Plantecam), weak institutional capacity to control exploitation, uncontrolled access into the forest, scramble for diminished stock by legal and illegal exploiters, destruction of wild stock by unsustainable practices, and insufficient regeneration of the species in the past have almost driven this species to extinction in certain parts of Cameroon and made it severely threatened in others. Prunus africana is presently threatened with extinction in the entire Mount Cameroon region. In response to this, the Mount Cameroon Project (MCP) and the Ministry of Environment and Forests (MINEF) helped some communities (Bokwoango and Mapanja) in the Mount Cameroon region to form Prunus africana harvesters’ unions with the aim of preserving the resource and improving the socio-economic benefits. The principal aim of the Bokwoango Prunus africana harvesters’ union is to ensure sustainable exploitation of Prunus africana while saving money for important development projects for individual members, their families and the entire community. This piece of work highlights the different facets of Prunus africana management in Cameroon in general and the Bokwoango community in particular. The study examines the socio-economic impact of Prunus africana management in the Bokwoango community and shows specifically the management role played by the Bokwoango Prunus africana harvesters’ union to reduce the rate of exploitation of Prunus africana and also to ensure benefit sharing of the earnings from sales of Prunus bark. It at the same time brings out the constraints encountered by harvesters as well as the opportunities that can make the union become more viable to the socio-economic development of the Bokwoango community. Results of this study show that for the short period that the Bokwoango Prunus africana harvesters’ union has existed, the socio-economic changes in this community are encouraging if one compares the present situation with that before the formation of the union. Most importantly, there has been increased awareness on the great need to conserve not only the threatened Prunus africana species but also other threatened plant and animal species in the region through sustainable hunting, harvesting and regeneration. Some proposals are made for efficient natural resource management and improvements on livelihood through alternative income generating activities. The study ends with recommendations for policy and institutional reforms as well as suggestions for further research in sustainable management of Prunus africana.</p>

Currently, there is widespread debate regarding the overall status of the world's fisheries, with some researchers projecting their total collapse in only a few decades, and others concluding the situation is not quite as bleak. Additional debates include what strategies should be used to manage fisheries at various scales, and further research is needed to determine which strategies are most appropriate for use in particular situations and locales, as context is critical. Recently, prominent common pool resources scholars have expressed the need for ethnographic approaches to studying resource management institutions in order to move beyond the current focus of simply identifying the factors and conditions that lead to the self-organization of resource users and long-term sustainability of management institutions. These authors describe the need for examining the larger context in which management institutions exist and taking various historical, political, and sociocultural factors into account when examining common pool resources. This dissertation is a response to that request. This research is the result of over 20 months of ethnographic research in St. Croix, United States Virgin Islands (USVI). Drawing on research in political ecology and building on anthropological critiques of common pool resource institutions, I describe the historical, social, and political factors that influence how fisheries management occurs at the federal and territorial levels, and how commercial fishers, managers, and other stakeholders experience and participate in multi-scale management processes. Ethnographic data suggest that there are a variety of historical, social, and political factors that influence how commercial fishers, managers, and other stakeholders perceive the federal fisheries management process, the extent of their participation in that process, as well as interactions within and between stakeholder groups. Additionally, the mismatch that exists between the centralized management structure of the US federal system and the small-scale, multi-method nature of St. Croix's fishery creates a complex management environment in which few stakeholders participate.

Successful intercultural natural resource management collaboration is challenged by divergent worldviews and power disparities. Studies of non-intercultural collaboration efforts demonstrate that good outcomes emerge when procedural conditions are met, such as fostering open and high-quality deliberations, use of interest-based bargaining techniques and collective definition of the scope of the process. The applicability of these procedural conditions to intercultural collaboration efforts, such as negotiations between Aboriginal people, government resource managers and sustainable forest license holders, has not been explored. The aim of this thesis is to examine the outcomes and factors influencing two intercultural collaborations in the northeast region of Ontario. Semi-structured interviews with collaboration participants, negotiation meeting minutes and draft agreements are used as data sources. Following a general inductive coding approach and using QSR NVivo 2, the analysis of outcomes in both cases highlights improvements in relationships, increased understanding among the parties and the gradual definition of the scope of the negotiation. The findings also demonstrate that several barriers, including a lack of clear policy and legislative framework for collaboration and different definitions of the problem discourage intercultural collaboration. In one negotiation process, frequent and high quality deliberations, using an interest-based negotiation approach, and efforts to mutually define the scope of the negotiation prior to substantive negotiation do not overcome these systemic barriers to collaboration. However, in another negotiation process, the social and relational characteristics of the community and participants do contribute to the parties recognizing their interdependence, focusing on shared goals and undertaking joint action. This research demonstrates that the development of shared goals and acknowledgement of divergent problem definitions are more important to intercultural collaboration success than the development of improved relationships and establishing a mutually acceptable scope prior to collaboration. In the absence of a supportive legislative basis for the distribution of forest decision-making authority and responsibilities, this understanding of how Aboriginal, government and forest industry participants can collaborate is useful for developing more effective and equitable intercultural collaboration.

Three complicated and interrelated issues are marine conservation, local development, and climate change. To seek insight into the challenges posed by these issues in a particular context, this dissertation focuses on seven communities near marine protected areas (MPAs) on the Andaman Coast of Thailand. The central question was “How can conservation outcomes and community livelihoods and adaptive capacity be enhanced in communities near MPAs on the Andaman Coast of Thailand in consideration of a changing climate?” The objectives were to explore local perceptions of social and environmental change and vulnerability, community opinions of Thailand’s National Marine Parks (NMPs), and the adaptive capacity of coastal communities. Literatures on resilience, adaptive capacity, vulnerability, conservation impacts, sustainable livelihoods, and governance and management frame the research. Fieldwork included Photovoice, interviews, and household surveys. Four stand-alone manuscripts are included in the dissertation: a) “A picture of change: Using Photovoice to explore social and environmental change in coastal communities on the Andaman Coast of Thailand”; b) “Vulnerability to multiple stressors in coastal communities: A study of the Andaman Coast of Thailand”; c) “Why local people do not support conservation: Community perceptions of marine protected area livelihood impacts, governance and management in Thailand”; and, d) “The capacity to adapt?: Communities in a changing climate, environment and economy on the northern Andaman Coast of Thailand”. Broadly, the dissertation offers relevant insights into the complex social-ecological changes being experienced by heterogeneous communities and the multi-faceted and multi-scalar actions required to address increasing challenges. Specifically, it a) demonstrates that Photovoice is an effective method for examining social and environmental change and providing input into community adaptation, conservation, and development processes, b) explores the social-economic and biophysical stressors that contribute to household vulnerability and suggests that multiple stressors, particularly economics and climate change, need to be considered in adaptation planning, c) recommends significant improvements to current NMP governance and management to engender local support for marine conservation, and d) illustrates that communities on the Andaman coast of Thailand are coping with environmental and fisheries declines, reacting to climate change and adapting variably to alternative livelihoods and proposes interventions for improving adaptive capacity. / Graduate / 0366 / njbennet@uvic.ca

Protected areas are of prime importance to conservation efforts worldwide because they provide society with a range of important environmental, economic, and social benefits. The ability of government agencies to manage threats to their national parks is often compromised by limited resources. There is a growing need to improve decisions about how resources are allocated amongst conservation responsibilities. Multiple Criteria Analysis (MCA) techniques are integrated decision systems that have the potential to reduce the complexity normally associated with decisions about public and quasi-public goods. The explicit expression of a decision-maker’s preferences for certain decision attributes is a key stage in the MCA process. The ability of MCA to increase the understanding, transparency, and robustness of decisions has been demonstrated in many disciplines. This research describes the development of a MCA model to assist decisionmakers with the allocation of resources amongst national parks. After a thorough review of the conservation and protected area literature, a MCA model is developed to determine the utility of a group of national parks based upon environmental, economic, and social significance. The model is tested and applied to the national parks managed by the Parks and Wildlife Commission of the Northern Territory of Australia and to selected parks managed by the Department of Conservation of New Zealand. The research highlights the need for protected area management agencies to take lessons from the commercial sector and incorporate elements of business practices, particularly comprehensive inventory and data management, into conservation decision-making. It is shown that the integrated decision-making approach taken in this research aggregates complex data in a way that improves managers’ ability to make better informed decisions concerning the allocation and distribution of resources.

Ethiopia has been challenged by multidimensional poverty. However, it has the potential to minimize the threat through an integrated multipurpose development process. In this regard, hydropower has a significant role to reduce energy poverty and enhance the multipurpose use of natural resources efficiency. Hydropower is a source of clean, sustainable and renewable energy. It has a contribution to reducing carbon emission and maintaining environmental sustainability. In Ethiopia, it is the major source of electricity. The country is rich in natural resources, including water to produce energy, however, electricity supply is still uncertain. The data shows that the country has the potential to produce 50,000 MW energy from water resources. Yet, it exploited 3,822 MW in 2018, approximately 7.6 % of its potential. Moreover, the country faces issues with energy security. Additionally, water and food supply also face an uncertain future. In this case, the country has planned the growth and transformation plan I and II for 2015 and 2020 to increase the energy production to 10,000 MW and 17,000 MW energy respectively. Consequently, the government launched different multipurpose hydropower plant projects. This project focuses on the multipurpose use of the Grand Ethiopian Renaissance Dam, particularly for the sustainable energy-water-food-ecosystem service nexus at the national level. I applied the combination of methods such as the energy-water-food-ecosystem nexus, the SWOT analysis and the sustainability assessment as they are suitable for the complexity of such a project. Indeed, the GERD has benefits for the country in producing renewable and clean energy, generating income and increasing the water storage capacity at the national level. However, the project neglected the values of ecosystem services integration with the dam and its sectors. As a result, the dam affected the existed terrestrial biodiversity and ecosystem. Therefore, the GERD had not been the well-prepared plan that considers institutional cooperation and sectoral integration to use for multipurpose function and its sustainability. In these regards, unless the dam to take proper management of the project and natural resources, the hydropower plant would not have been generating sustainable energy production. / <p>The paper shows that how to use the reservoir hydropower plant for multipurpose, such as for energy, water, food, ecosystem services integration at local level</p>
