Evaluating ecological integrity and social equity in national parks : case studies from Canada and South Africa

Timko, Joleen Allison 05 1900 (has links)
There are concerns that many national parks worldwide are ineffective at conserving biological diversity and ecosystem processes, are socially unjust in their relations with Indigenous communities, or both. This dissertation asks: can national parks protect ecological integrity and concurrently address social equity issues? It presents empirical results of a systematic evaluation of six case study national parks in Canada and South Africa. Purposive sampling was used to select the six case study national parks. Data sources included State of the Park Reports; park ecological monitoring data; archival data; and semi-structured interviews with park biologists, managers, and Indigenous members of park co-management boards. Status and trend assessments and effectiveness evaluations of park ecological monitoring data were used to evaluate how effectively the parks addressed three ecological integrity criteria. Results show that all six parks effectively addressed the priority indicators for which they had monitoring data. However, the effectiveness ratings of each park decreased when all indicators, including those identified as priorities but lacking monitoring data, were analysed. This indicates that the parks had generally identified more priority indicators than they were actually able to address (for reasons including lack of budget or trained staff, managerial challenges). Thematic coding of semi-structured interview and archival data, and the assignation of numerical ratings to these data, were used to evaluate how effectively the parks addressed three equity criteria. Results show that all but one of the case study parks were equitable, parks with more comprehensive co-management and support from neighbouring Indigenous groups were more equitable than parks with lower levels of co-management, the parks with settled land claims were not necessarily more equitable overall, and a few parks were found to be co-managed in name only. The overall results of this evaluation demonstrate that parks effective at protecting ecological integrity can also successfully address social equity, but that further efforts to integrate these two realms are both possible and necessary. A logical starting point would be to build upon those existing integrative processes already institutionalised in many parks and protected areas: the co-management and integrated conservation and development efforts.

Multiple perspectives for envisioning marine protected areas

Ban, Natalie Corinna 11 1900 (has links)
This thesis provides the first direct comparison between – and integration of – community-based and science-based approaches to the establishment of marine protected areas (MPAs). MPAs are one potentially effective conservation tool, but are being established very slowly. My research shows that community involvement in placing MPAs can help meet many ecological goals, although biophysical data improve the conservation value of sitings. To assess the need for MPAs in British Columbia (BC), Canada, I mapped stressors resulting from human activities. This produced a powerful rationale for MPAs: very little of the ocean, and almost none of the continental shelf of BC, lies beyond the reach of human stressors. My work helps reconcile differing perspectives about the efficacy of community-based vs. science-based MPA selection. I explored and analyzed these approaches, separately and together, in two areas in BC. First, I generated a community-based plan for MPA placement through partnerships with two First Nations (indigenous peoples) in BC. They offered strong support for spatial protection measures, and individuals nominated overlapping areas. Second, I applied a decision support tool (Marxan) to determine MPA placement under scientific precepts. Conservation planning usually lacks detailed ecological information but the Marxan approach was robust to some missing data; in such cases, it was best to use available abiotic and biotic data to ensure that both habitats and species were represented. Third, I integrated community-based and science-based approaches, to find that they verified and complemented each other. Indeed, an integration of the two was preferred by participants and also achieved all conservation objectives. Finally, I took a novel and pragmatic approach to ocean zoning. I used spatial data for thirteen commercial fisheries on Canada’s west coast to select areas where fishing should be permitted, rather than prohibiting fishing under a MPA paradigm. The results revealed that small reductions in fisheries yields, if judiciously selected, could allow creation of large unfished areas that embraced diverse biophysical regions and habitat types. Such a pragmatic approach could achieve remarkable conservation gains.

Acoustic Monitoring of Scotian Shelf Northern Bottlenose Whales (Hyperoodon ampullatus)

Moors, Hilary B. 26 June 2012 (has links)
An important step for protecting Endangered species is the identification of critical habitat. This can be especially challenging for deep ocean species. Northern bottlenose whales (Hyperoodon ampullatus) are deep-diving beaked whales of the North Atlantic. A population of this species occurs along the edge of the Scotian Shelf primarily in three submarine canyons that have been identified as critical habitat for the population: the Gully (the largest submarine canyon off eastern North America), Shortland Canyon and Haldimand Canyon. The Scotian Shelf population is considered Endangered mainly due to its small numbers and the anthropogenic threats it faces. The primary objective of my research was to further identify critical habitat of the population using passive acoustic monitoring, increasing knowledge of how the whales use the canyons and adjacent areas throughout the year. A review of the literature on cetacean associations with submarine canyons indicates that various mechanisms may act to attract cetaceans to these features. While many different species occur in canyons globally, they appear to be particularly important habitat for beaked whales. I developed an automated click detection algorithm customized for detecting northern bottlenose whale echolocation clicks, and long-term acoustic recordings were analyzed to examine the presence and relative abundance of northern bottlenose whales on the Scotian Slope over various spatial and temporal scales. The whales occurred in the area consistently throughout the year and all three canyons, as well as the area between canyons, appeared to be important foraging grounds for the population. The whales displayed diurnal foraging patterns. I also investigated niche separation between northern bottlenose whales and sperm whales (Physeter macrocephalus), another deep diving species. The presence of the two species was positively correlated over all spatial and temporal scales examined. These results indicate that areas within and adjacent to the Gully are important foraging grounds for northern bottlenose whales throughout the year. Furthermore, in addition to the canyons themselves, the shelf-edge areas between the Gully, Shortland and Haldimand canyons may constitute critical habitat for the whales. This research will be used to inform management measures relevant to the protection and recovery of this Endangered population.

Assessing Community Conditions that Facilitate Implementation of Participatory Poverty Reduction Strategies

Muruvi, Wanzirai 05 December 2011 (has links)
The goal of the current study was to describe the organizational and institutional foundations within traditional rural communities that facilitate implementation of participatory community poverty reduction programs. The focus was on communities within or adjacent to protected areas. A case study research approach was used to assess community mobilization, participation and analytical capacity and also to evaluate community groups and organizations for their competence to be local implementing agents of poverty reduction programs. The research findings showed that inadequate skills and organizational levels limited the ability of communities to fully utilize protected areas as poverty reduction initiatives. Key determinants of community participation were the ability to mobilize and also to undertake detailed analysis of local situations. Community mobilization depended on the relationship between the mobilizing agent and the community, social cohesion and gender. Analytical capacity was influenced mostly by the level of education, prior experience and gender. Interestingly, community groups that had the highest potential to be implementing agents, had strong ties to traditional institutions, suggesting that groups with well recognized power and legitimacy within the community are better positioned to facilitate implementation of community poverty eradication initiatives. A number of indicators of community competence were identified and these were used to develop an analytical framework that can be used as a diagnostic tool for determining community competence. / Protected Areas and Poverty Reduction - Canada-Africa Research and Learning Alliance Project
