The objective of this thesis is to quantitatively understand the economic performance of protected area management strategies for forest and biodiversity conservation. Examples such as integrated conservation and development and eco tourism are assessed in terms of their ability to deliver on welfare benefits to local communities, and an assessment of the opportunity costs of forest conservation as a land use strategy. In addition the contribution of forest conservation in protected areas can make to poverty alleviation and economic development is also examined. The geographical focus of this study is the Albertine Rift region of East and Central Africa, stretching north from the southern end of Lake Tanganyika through the spine of Africa to the northern end of Lake Albert. The Albertine Rift is one of Africa’s most important landscapes for the conservation of forests and biodiversity. The overarching objective is addressed using a series of case studies empirically valuing the opportunity costs of conserving forests in a selection of sites in the central part of the Albertine Rift. The success of conservation is most often measured against progress in reducing habitat or species loss and not often in terms of the contribution of the protected area to poverty alleviation and local economic development. Achieving improvements of conservation strategies in the social dimension requires objective evidence on their effects. Economic valuation of protected area resources provides a quantitative means of assessing the promise and performance of conservation policies in achieving welfare benefits to local communities. This thesis provides three case studies each addressing current valuation and social issues in conservation and sets them in a context of managing protected areas in the broad dynamic setting of poverty alleviation and economic growth from a developing economy perspective. In addition two of the empirical studies are as concerned with methodological enquiry and the performance of novel environmental economic valuation techniques, such as the contingent valuation and choice modelling approaches, as the application of results to conservation questions. The empirical studies show that the benefits to local households and communities from their local forests may be greater than at first perceived. Across all protected area categories, biomes and income groups, households derived significant amounts of their overall income from their local protected area with large proportions of the value of goods harvested from forests being consumed in the home. Amongst income groups high income households often appropriated a greater share of the value of forest goods. There was no significant difference found between the household consumption and the sale of protected area products between income groups. The findings indicate that imposing reductions in forest use may increase poverty amongst local people whilst increasing household income will not necessarily reduce forest exploitation. This indicates that community conservation and integrated conservation and development programmes must target the poor forest adjacent households more actively to ensure poverty alleviation, whilst providing improved protection and law enforcement for effective conservation. It is also shown that biodiversity conservation can have an economic return through mountain gorilla eco-tourism. Findings show a disparity between what constitutes eco-tourism and the real values of tourists towards biodiversity conservation and local social benefits from protected areas. Despite showing a high marginal utility for biodiversity conservation, consumers are unwilling to pay for local community benefits from tourism as part of the permit price to view gorillas. Clearly the link between successful conservation and the welfare status of local communities is not sufficiently established in the minds of consumers to influence their spending decisions. The challenges of effectively mobilising communities to protect biodiversity are discussed in the context of the variable impacts of integrated conservation and development programs over the last three decades. Direct payment payments for conservation services schemes are discussed as an innovative tool to add to the gamut of community approaches currently on offer. Payments for conservation schemes are viewed with cautious optimism in terms of their possibility for success. Despite their allure of being more economically and socially efficient at achieving welfare and conservation objectives, given the complex nature of any society, no less research in to social and economic dynamics of protected area use by local communities would be needed to ensure success of such schemes. However, the overwhelming majority of benefits form protected areas are tied up in ecosystem services values. Mechanisms to generate funding and distribute payments for these benefits in terms of offsetting the local opportunity costs are essential to change local behavior and reduce forest degradation and destruction.

Depuis les années 90, les Projets Intégrés de Conservation et Développement ont été présentés comme des modèles fonctionnels de développement durable pour un site spécifique dans une perspective de réalisation. Le but est d’intégrer les objectifs biologiques de la conservation aux objectifs sociaux et économiques du développement. Ces projets, qui répondent à de multiples dénominations et stratégies, sont implantés dans des contextes naturellement hétérogènes et dynamiques, où l’aménagement du territoire ne doit pas être un outil de planification étatique, désigné et imposé dans une logique conservationniste. Les aires protégées représentent une certaine vision du rapport entre l’être humain et la nature, apparue dans le contexte nord-américain avec la création des premiers grands parcs nationaux en 1870. Aujourd'hui, la forte volonté d'impliquer la population se heurte avec la difficulté de concilier la gestion de ces espaces avec les pratiques, les nécessités et les intérêts locaux. Le parc naturel Obô, qui occupe 30% du territoire de São Tomé et Principe, doit affronter la difficile intégration entre les représentations de la nature et les usages locaux avec les objectifs globaux des politiques conservationnistes, ainsi qu’avec les intérêts touristiques et économiques des investisseurs locaux et étrangers. Les représentations sociales de la nature, établissant une forme de connaissance pratique, déterminent la vision du monde et la relation qu'un certain groupe social peut avoir avec le territoire. Ainsi, chaque communauté possède ses propres mécanismes d'adaptation au milieu basés sur ce système représentationnel. Dans le cas des communautés sãotoméennes, la nature présente un caractère spirituel (associé à des croyances, des rites et des pratiques médicales traditionnelles) et utilitaire (la nature, à travers l'agriculture, la récolte ou la chasse, répond au besoin de subsistance). L’objectif de ce projet de thèse est donc de mieux comprendre la synergie existante entre savoir endogène et gestion de la biodiversité pour adapter l’aménagement du territoire à la réalité des populations qui y vivent. / Since the beginning of the 1990s, Integrated Conservation and Development Projects have offered a functional model of sustainable development for specific sites within the perspective of particular projects. Their goal has been to integrate biological aspects of conservation to the social and economic aspects of development. Protected areas represent a particular vision of the relationship between man and nature, appeared in the American context with the creation of the first national parks. Currently, the wish to involve the population in the creation of protected areas faces the challenge of reconciling the management of these spaces with the local practices, needs and interests. Obô Natural Park, which occupies 30% of the territory of Sao Tome and Principe, follows the difficult process of integrating both local uses and representations of nature to the global objectives of conservationist policies while considering the touristic and economic interests of local and foreign investors. Social representations of nature, understood as a form of practical knowledge, determine the vision of the world and the relationship that a particular social group may have with its territory. Thus, based on this system, each community has its own mechanisms of environmental adaptation. In the case of the Saotomean communities, nature presents a strong spiritual (associated with beliefs, rituals and traditional medical practices) and utilitarian character (nature provides, through farming, collecting or hunting, all you need to live). The aim of this thesis is to understand the synergies between endogenous knowledge and management of biodiversity to adapt the land management process to the reality of the people who live in the particular territory of Sao Tome and Principe.

There is considerable geographical overlap between areas set aside for nature conservation or protection and Indigenous peoples’ lands, and the social, economic, and political consequences of protected areas have often been extensive for Indigenous peoples. Discourses of conservation converge with discourses of Indigenous peoples, and both carry a legacy of colonial constructs and relationships. With these overlaps as a point of departure, the purpose of this thesis is to explore how the discourses that govern nature conservation and protected areas shape the conditions for Indigenous peoples’ influence and participation in the governance and management of protected areas on their lands. I pursue this aim by analyzing, and critically examining the consequences of, the construction of Indigenous subject positions and conditions for agency in discourses of nature conservation and protected areas. The empirical focus of the thesis lies with international discourses of protected areas and Indigenous peoples and on local and national discourses articulated in relation to two cases of protected areas in Sápmi. My analytical framework builds on postcolonial theory and discourse theory. I use space for agency as a concept to describe and analyze the effects of the discursive positionings and constructions that shape the ability or capacity of individuals or group to act or to be perceived as legitimate actors. My results show twomain articulations of Indigenous subject positions in protected area discourses, which enable and restrain the space for Indigenous agency in different ways. One articulation connects Indigenous peoples to conservation through the concept of traditional knowledge, thereby positioning Indigenous subjects mainly as holders of traditional knowledge and justifying Indigenous influence by its potential contribution to conservation objectives. The other articulation focuses on the rights pertaining to Indigenous peoples as peoples, including land rights and the right to selfdetermination. These articulations are not necessarily mutually exclusive, but they have potentially different consequences and indicate discursive tensions that can affect the space for Indigenous agency in relation to protected areas. Moreover, my results demonstrate the hegemony of discourses that takes conservation through area protection for granted and subordinates Indigenous land use to conservation objectives, structure Indigenous agency as “participation” in specific types of arrangement, and articulate Indigenous rights in relation to hegemonic constructions of sovereignty, self-determination, and rights. These hegemonic formations silence articulations that would challenge the authority of colonizing societies over Indigenous territories, suppress radical critique of the fundamental nature of arrangements for protected area governance and management, and subdue alternatives to discourses of contemporary liberal democracy and individual property rights.

The objective of this thesis is to develop an ecological economic framework for the assessment and establishment of protected areas (PAs) that are aimed at conserving forests and biodiversity. The framework is intended to be both rigorous and relevant to the decision-making process. Constructivism is adopted as the paradigm guiding the research process of the thesis, after firstly examining also positivist philosophy and ???post-normal??? scientific methodology. The tenets of both ecological and environmental economics are then discussed. An expanded model of human behaviour, which includes facets derived from institutional economics and socioeconomics as well as aspects of neoclassical economics, is outlined. The framework is further developed by considering, from a contractarian view point, the implications of intergenerational equity for biodiversity conservation policies. The issues of intragenerational distribution and allocation are then considered. In this regard, cost-benefit analysis (CBA), as applied to the valuation of forests, PAs, and biodiversity, is critically reviewed. A participatory approach to decision-making, which may also include CBA, is then proposed. The resulting ecological economic framework may be thus summarised: (a) ecosystem use patterns should be chosen on the basis of their sustainability, distributional, and efficiency aspects; (b) systems of PAs should be established in order to achieve minimal intergenerational equity; (c) intragenerational equity requires the correction of the asymmetrical distribution of the costs and benefits arising from the establishment of PAs; (d) the institutional features relevant to the environmental-economic issues being analysed should be considered; and (e) the decision-making process should be participatory and action oriented. The framework is applied to two case studies in Vanuatu. These applications detail (a) stakeholders??? views and trade-offs faced in relation to forest management (b) modes of participatory research and decision-making, (c) forms of compensation that may be adopted in correcting asymmetrical distributions of the costs and benefits of PAs, and (d) institutional influences on ecosystems use and implications for conservation projects. The institutional arrangements developed for the establishment of the PAs are presented. The application of this ecological economic framework has resulted in the formal establishment of one PA and the identification and assessment of five other PAs.

Thesis (M.Tech.: Information Technology)-Durban Institute of Technology, 2005 iii, iii, 85 leaves / Throughout Africa, growing human populations and resulting loss of wildlife habitat is a critical issue for most animal species. It is more and more common for privately owned small or medium sized farms to reintroduce wildlife on their land and such protected areas are fast becoming the only refuges available to wild animals. However a comprehensive understanding of the complex ecological processes taking place is vital for the effective management of restricted areas and the conservation of biodiversity. Due to the enormous complexity of an ecological system and the long periods of the related dynamics, it is very difficult to analyse the interaction between animals and plant populations without suitable computer models. In this thesis, the dynamics between elephant and trees (a major food source) are considered using computer simulations.

This thesis provides an analysis of recent attempts to regulate the governance of genetic resources through the initiation of new global commons regimes. These attempts have arisen out of a combination of the growing recognition of genetic resources' value and global nature; a new resurgence in support for the common property paradigm; and, during a period in which the world is becoming increasingly globalised, with many governance competencies moving to the supranational level. They can be viewed as part of a broader effort to proffer the common property approach as a legitimate alternative in the property regime debate: a debate that has increasingly become trapped in the public-private dichotomy at the dawn of the twenty-first century. The aim of this thesis is to investigate the success of these attempts, and offer suggestions about how future attempts might be more successful. While there are a multitude of books, articles, opinion pieces and media reports produced that concern themselves with property theory, intellectual property theory, the efficacy or morality of applying property regimes to living materials, and the threats and promises of globalisation, all of which influence the notion of a potential global genetic commons, relatively little has been written directly on the idea of applying global common property regimes to genetic resource governance issues. The first part of this thesis constructs a theory of a global genetic commons, drawing inspiration from a variety of sources, while the second part tests this theory in order to analyse the outcomes of the recent attempts, and suggest directions for future research. The thesis finds that the conception of a global genetic commons is indeed a valid one, and that while not all attempts so far have been successful, the common property paradigm does offer valuable insights for the future governance of genetic resources at the global level.

The freshwater fish fauna of southern Australia is characterised by low species richness and high endemism in groups displaying southern temperate, temperate-subtropical or temperate-tropical distributions. Comparatively few studies in Australia have incorporated modern molecular techniques to delineate species boundaries and define within-species conservation units. This is problematic because freshwater fishes are likely to show high levels of cryptic speciation and marked spatial sub-structure, and is information which is needed to conserve biological diversity and maintain the integrity of ecological communities and processes. The current study uses a ‘combined evidence’ approach, led principally by a set of nuclear genetic markers (allozymes), to assess species boundaries, spatial sub-structure and conservation units in obligate freshwater fishes from southern Australia. A literature review (Chapter 2) concerns the nature and effects of fragmentation in freshwater environments. It considers the implications for freshwater fishes and the types of extrinsic and intrinsic characteristics, both natural and human accelerated, that might drive population fragmentation and divergence. This theoretical framework is then applied to a suite of six largely co-occurring species groups with contrasting biological characteristics, and derive hypotheses about expected levels of genetic divergence across and within different drainages. Major findings Species of Retropinna (Chapter 3) are widespread and generally regarded as ‘common’ and mobile. Allozyme analyses revealed species-level and population-level sub-divisions, including five distinct species with contiguous ranges and no evidence of genetic exchange. Three occur along the eastern seaboard (including three instances of sympatry), another in coastal and inland southeastern Australia and Tasmania, and a fifth in the Lake Eyre Basin. There is no indication of a simple ‘tasmanica’ versus ‘semoni’ dichotomy, but instead a complex pattern involving discrete clusters for the Upper Murray plus Darling rivers, Lower Murray, Glenelg River and Tasmanian regions. These findings have implications for biodiversity, conservation and ecology. This chapter has been published in modified form (Marine and Freshwater Research 58, 327- 341). Nannoperca obscura (Chapter 4) is a small demersal fish with specialised habitat requirements. It is under threat of extinction, particularly in the western section of its range. Combined nuclear and matrilineal genetic data identified congruent within-species sub-structure, divided by patternsof distribution and biogeography. Four monophyletic mtDNA lineages, each distinct at multiple nuclear loci, indicate four Evolutionarily Significant Units (ESUs), namely (1) Lake Alexandrina in the Murray-Darling Basin (MDB), (2) Glenelg River, Millicent Coast River Basin and the outlying Mt Emu Creek, (3) Merri River and associated coastal streams, and (4) the eastern range section. Additional genetic and ecological data support multiple Management Units (MUs) within ESUs for individual or groups of river basins separated by marine barriers. Nannoperca australis (Chapter 5) has a similar character to its aforementioned congener, except that it occurs across a much wider area. Although generally common, particular populations are threatened, especially in the MDB. Allozyme analyses of 57 populations confirm the presence of two divergent species, with an eastern species containing two ESUs: (1) Gippsland and Flinders Island, and (2) Ansons River in northeastern Tasmania. The western species shows sub-structure across its range, including a separation of MDB and coastal populations as two heterogenous ESUs. The Lower Murray region (Mount Lofty Range streams and the Lower Lakes) harbours a remarkable level of between- and within-population diversity, underscoring its importance for conserving evolutionary potential. Mogurnda adspersa (Chapter 6) has been presumed extinct in South Australia since the early 1970s and has also been assumed lost from the southern MDB. This chapter reports on the rediscovery of M. adspersa from a wetland near the terminus of the Lower Murray, some 2500 river kilometres from the nearest known population. The nature and basic ecology of this population is documented, but the combined effects of drought and water abstraction recently have led to the probable extirpation of the wild population. A combined allozyme and mtDNA dataset confirmed the ‘nativeness’ of the population as a distinct sub-population (and MU), with a moderate level of allele heterogeneity. This information provides a platform for captive breeding as a conservation measure. The endemic genus Philypnodon (Chapter 7) contains two nominal species: P. grandiceps and the long recognised but only recently described P. macrostomus. The former is considered widespread and common (near ubiquitous), whereas the latter is more patchily distributed. Some tolerance to marine conditions is indicated, suggesting that there may be less sub-structure, but allozyme analyses of 269 individuals indicate the presence of multiple, species-level taxa within both described species. This obscures interpretations of existing ecological data. Although the presence of genetically-similar populations within and across some drainage divides indicates higher levels of gene flow, the pattern is complex and suggests historic genetic exchange between some but not other geographically-adjacent taxa. The freshwater blackfish genus Gadopsis (Chapter 8) has been a problem group for taxonomists, and it is unclear where the group is placed phylogenetically and how many species occur. Northern and southern forms on respective sides of the Great Dividing Range have been proposed, but with limited supporting evidence. Its dispersal ability (hence predicted genetic structure) is obscured by opposing life-history traits, including large body size (i.e. good swimming ability) versus habitat specialisation, demersal larvae and restricted home ranges. This chapter provides a genetic overview incorporating 61 locations across the range, and demonstrates unequivocally the presence of distinct northern and southern species of G. ‘marmoratus’. Moreover, distinct genetic discontinuities involving geographically abutting lineages indicate the likely presence of multiple ESUs within each species. A comparison of the allozyme data with previous mtDNA studies also identified two ESUs within G. bispinosus. Overall, considerable complexity is demonstrated signalling the need for a review of how the southern Australian fish fauna should be viewed, studied and protected. The genetic data also provide insight into the interplay of intrinsic biological characters (e.g. dispersal ability, population ecology) with historic and contemporary extrinsic environmental factors (e.g. fragmentation, biogeographic processes). Comparisons between and within traditionally-defined species are problematic, however, owing to multiple species-level splits and other genetic divisions that may have matching biological counterparts. Together with other reports in the literature, the findings presented herein have significant conservation implications, particularly given the rapid pace of human-mediated change in some regions that house high species and genetic diversity and unique evolutionary components, notably southeastern Queensland (especially the Mary River) and the lower River Murray in South Australia. Other regions displaying high genetic substructure or divergent populations include the Clarence River and Lachlan River in New South Wales; Gippsland, Goulburn River, Glenelg River and Mt Emu Creek in Victoria, and the Macquarie River and Ansons River in Tasmania. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1339749 / Thesis (Ph.D.) - University of Adelaide, School of Earth and Environmental Sciences, 2008
