Protected areas in Kenya constitute 7% of the total land area with over 75% of wildlife in the country being found on private or communal land. Wi th one of the highest population growth rates in the world and facing a range of developmen t issues with limited resources, one of the greatest challenges in Kenya is reconciling and sus taining economic development with biodiversity conservation and sharing the costs and benefits of conservation between individuals, state and the general community. The study was info rmed by the relevant literature and the researcher’s fieldwork which was conducted in 2008 in three categories of protected areas under different governance types and primary management o bjectives in Kenya (Lake Nakuru National Park – government managed, Kimana Community Wildlif e Sanctuary – communally managed, and Kedong Game Ranch – privately managed). The res earch examined the general issues of how local communities in Kenya have embraced differ ent biodiversity conservation strategies. A major emphasis was on identifying those factors inf luencing their attitudes towards conservation approaches and their participation in conservation management institutions. At issue was whether support for a particular conservation strat egy is primarily a function of communities’ experiences with biodiversity decline or their rela tionship with the conservation authorities. The research employed both qualitative and quantitative techniques in gathering the data. A total of 270 community respondents and 45 staff respondents were interviewed. Several demographic and socio-economic characteristics of the local peo ple that include age, gender, educational level and location, amongst others, were found to signifi cantly influence the attitudes of the local people towards the protected areas conservation act ivities. The direction of the influences (whether positive or negative) depended on the mana gement category of the particular protected area. The general findings of the study suggest tha t although local people appreciate the crucial value of biodiversity and the role of protected are as in conserving it, there is some evidence of resentment towards some management activities of th e protected area regulators. Negative attitudes were attributed to perceived problems of living next to the protected areas such as lack of involvement of the local people in the managemen t of the protected areas, restrictive access to and use of resources from the protected areas, hara ssment by the conservation enforcing agents, conflicts with wildlife and lack of compensation fo r damages and losses incurred. Widespread support for the management activities was associate d with perceived benefits to the local populations such as support for educational program mes, social amenities, employment and business opportunities. It is clear from this study that different rationales of conserving biodiversity need to address the issue of protected area management in the context of sustainable development through a combination of conservation s trategies. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2010.

<p>Developing countries often hoard the largest number of species, but also experience very high poverty levels. This dissertation reviews the evidence of the performance common conservation interventions. I find that despite the billions of dollars channeled towards conservation efforts annually, there is still very limited evidence whether or not conservation policies work. The evidence has been limited to exceptional countries like Costa Rica and Thailand and outlines like deforestation, without considering ecosystem function and ecosystem services. Furthermore, I find that the conservation impact evaluation literature has currently not highlighted the channels through which conservation policies effect change and how the effectiveness varies with the baseline characteristics of the area. </p><p>This dissertation aims to address some of the gaps in current conservation literature. Focusing on Indonesia between 2000 and 2006, I evaluate the performance of protected areas in terms of stalling deforestation as well as providing a wide range of ecosystem services and benefits (Chapter 2). In Chapter 3 I examine the role of context in which protected areas operate and show significant heterogeneity in their performance. In Chapter 4 I develop a static spatially explicit model of household fuelwood extraction that allows me to predict the location and magnitude of spillovers when a protected area is introduced. I find that depending on the characteristics of the areas, it may be optimal for households to buy fuelwood than collect it.</p> / Dissertation

Over the next three decades, there are many predicted disturbances to Earth’s oceans, such as El Nino and hurricanes, which will lead to mass coral bleaching effects. Marine protected areas have been utilized worldwide to maintain coral population sizes and remediate external stressors, such as overfishing or mining. Using a series of modeling techniques, this thesis will propose an experiment that will determine the optimal distance and location for a future MPA in New Zealand. It will also be measuring whether one large reserve or a network of smaller MPAs are more effective in the regeneration of stony corals. These models will be based on Solemosmilia variabilis, the most common stony coral in the region. Based on past studies, it is hypothesized that there will be a significant positive increase with the metapopulation growth of corals in both protected areas. It is also predicted that there will be a higher rate of connectivity within a network of smaller marine protected areas if the MPAs are less than 2 km apart. If the distance is greater, one larger MPA will be more effective due to the lower rates of genetic drift.

Since its inception, ecotourism has been promoted as a solution to some of the problems of biodiversity conservation. It has been touted as having the potential to balance the diverse interests of various publics by ensuring the protection of landscapes from development and extraction, offering unique tourism experiences, contributing economically to local communities, and fostering support for conservation efforts. Inconsistent success in achieving these goals, however, suggests that the effectiveness of ecotourism ought to be assessed on a case-specific rather than an industry-wide basis. Further, different stakeholders are likely to perceive the impacts of ecotourism in very different manners. The research on ecotourism and conservation rarely considers multiple perspectives, instead reflecting a one-sided understanding of the issues. As a step towards addressing these shortcomings, this thesis brings to light differing perspectives of ecotourism at the site of Algonquin Provincial Park. Through interviews and surveys, I uncover differences in conceptualisations of key ideas of conservation, knowledge of Algonquin Park, and perspectives of ecotourism between two primary groups of participants: tourists visiting the park and residents living in surrounding areas. Their responses reveal that, to residents, the park is a representation of livelihood; for tourists, the park represents ???pristine nature.??? The park is staged for its various publics, strategically representing only those aspects that will be looked upon favourably to a given group. These multiple constructions may be beneficial, however, as diverse viewpoints of these participants prompted attitudes and behaviours that were advantageous to the varied objectives of the park???s mandate, ultimately contributing to the success of the park as a site of landscape and biodiversity conservation.

Biodiversity is a fundamental part of the functioning of ecosystems and their ability to provide ecosystem services. It has been shown that a high biodiversity increases the robustness of an ecosystem according to the insurance hypothesis. I propose that a similar effect can be seen on a higher scale, where a high diversity of ecosystem types might stabilize the ecological functionality of a region. By comparing eleven network characters in 70 tropical and temperate ecosystems, their diversity was measured as Euclidean distance between the systems in the 11-dimensional room defined by these characters.  The diversity of ecosystems was shown to be significantly higher in tropical latitudes than in temperate. A possible explanation to this result could be that the higher species diversity in the tropics allows for more types of ecosystems. A higher diversity of ecosystems in a region might indicate a larger amount and variation of possible ecosystem goods and services as well as provide the region with an increased robustness. The measurement of ecosystem diversity between regions might also be of importance in a conservation perspective, where unique and vulnerable ecosystems can be discovered and protected.

Coming together to save the Earth. Ten years have passed since the Earth Summit in Rio created such passion and expectations. Whether the Convention on Biological Diversity has met those expectations or not vary from person to person. / Evidently, the Convention on Biological Diversity is complex, not only in its language, but also in its attempt to balance between conservation and sustainable use, and between the providers of and benefiters from biological diversity. / Subsequent to its conclusion, the Parties have strived to achieve these objectives. This thesis attempts to assist in this process by exploring the means of implementing the Convention on Biological Diversity and their consequences. / The scope of the thesis is limited to the matters of sovereignty rights and access to genetic resources, in an effort to clear up the uncertainties in the applications of these components. This thesis attempts to contribute a pragmatic perspective to these matters, which, at their core, rely on the crossing points in the implementation of the Convention on Biological Diversity and the Agreement on Trade-Related Aspects of Intellectual Property Rights. This thesis focuses on ways to reconcile property rights in genetic resources with patent rights in invention using genetic resources. It proposes one interpretation of property rights in genetic resources so as to avoid any conflict with patent rights and accordingly, avoid conflict between the requirements of the Convention on Biological Diversity and those of the Agreement on Trade-Related Aspects of Intellectual Property Rights. / I hope that the views and proposals expressed in this thesis will be considered along with other diverse approaches to the implementation of the Convention on Biological Diversity.
