- Description: The development of wind energy is increasing globally and is often considered more environmentally friendly when compared to fossil fuel technologies. However, one of the ecological drawbacks of wind energy are the collisions of wildlife with turbine blades. In addition, the resulting anthropogenic landscape transformation can negatively impact populations. The Cape Vulture (Gyps coprotheres), a large endangered southern African endemic species, thus may be at risk from turbine development. The species has decreased dramatically in the past 50 years and understanding how additional mortalities from wind turbine impacts affect the population is needed to ensure effective conservation efforts. This study aimed to determine the population response to this emerging threat. This study first reviewed the species-, site- and wind farm- specific traits that make Gyps species vulnerable to collision with wind energy infrastructure. It examined the monitoring practices employed during the pre- and post-construction phase and mitigation measures in South Africa and compared it with international standards. Furthermore, wind energy development may disrupt landscape connectivity and understanding which, and how habitat patches are used is needed. Using network theory combined with telemetry data from tagged individuals across three age classes, habitat patch use was identified. Further, environmental variables associated with identified habitat patches were identified. Additionally, considering the wind energy industry is expanding in South Africa, exploring how the Cape Vulture population will respond to this novel and emerging threat may aid future conservation management plans. Therefore, using a population viability analysis approach, the study explored how present and future wind turbine mortality scenarios impact the Cape Vulture population and how the population will respond to increased wind turbine development. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The escalating levels of poverty present a serious challenge of vulnerability to most citizens of Lesotho. The government of Lesotho and its Non-Governmental Organisation (NGO) partners have been engaged in several programs aimed at alleviating poverty, whose persistence has threatened the current and future generations of the country. This study aimed at assessing the sustainability of NGO`s poverty alleviation programmes established for selected beneficiaries in rural communities. The main participants in this study were beneficiaries of poverty alleviation projects, government officials and NGO project managers. Using a combination of empowerment, sustainable livelihood approach and the sustainable development theoretical frameworks, the study adopted the qualitative research methodology to investigate the pertinent issues. The research design was a case study which helped to direct the researcher in the process of collecting and analyzing data. The study revealed that the sustainability of these projects in poverty alleviation remains questionable due to a number of challenges. These challenges include; lack of participation of the beneficiaries, inadequate funding, natural disasters, lack of commitment of the beneficiaries and lack of government support to the project beneficiaries. Nevertheless, there are commendable efforts made by the NGOs involved to enhance the sustainability of these projects and these include; training the beneficiaries in crop production, marketing, natural resources management and disaster management. In light of the challenges faced by NGOs and participants in alleviating poverty, this study advocates, The three stakeholders are expected to work harmoniously together using communication channels that are open to all of them. That enables them to work with a singleness of purpose to attain the sustainability goals of the project. There is need also for NGOs to reconsider their targeting schemes, and to advance their training, monitoring and evaluation skills of their projects. It also recommended that the beneficiaries must be empowered in order for the sustainability of the projects to be realized. , Thesis (MSoc (Dev)) -- Faculty of Management and Commerce, 2011
