Abstract:
Throughout the Pacific, many species of echinoderms and molluscs have cultural value and are harvested extensively in subsistence fisheries. Many of these species are sedentary and often associated with distinct reef-top habitats. Despite the significance of reef habitats and their fauna for fisheries and biodiversity etc, little information has been available on the distribution of habitats and their influence on the reef-top fauna in the Cook Islands. This thesis developed a novel approach to assess the status of the shallow-water reef-tops of Rarotonga, Cook Islands, to provide critical inf

Abstract:
Fisheries managers have the potential to significantly improve reef fish management in the Gulf of Mexico through the use of ecosystem-based approaches to fisheries management. Ecosystem-based approaches are needed to address the effects of fishing on trophodynamic interactions, to better account for ecosystem-scale processes in model projections, and to recognize the short and long-term biomass tradeoffs associated with making regulatory choices. My research was concentrated around three objectives: (1) characterizing the trophodynamic interactions between Gulf of Mexico fishes, in order to c

Abstract:
Under the growing demand for marine fish resources, and the apparent and expected impacts of global climate change, there is a need to conduct long-term monitoring (LTM) to ensure effective management of resources and conservation of biodiversity. However LTM programmes often suffer from design deficiencies and fail to achieve their objectives. These deficiencies stem from the fact that insufficient consideration is afforded to the design phase, with programmes selecting methods that are not suitable to address the objectives, or are not cost-efficient, compromising the sustainability of the L

Abstract:
The institution of the civil service is of much contemporary interest here in Britain and elsewhere. The phenomenon of civil service reform forms a significant part of the wider movement to remould public services or in the now legendary phrase, to ‘reinvent government’ on what could be perceived as a global scale, ranging from the more sophisticated democracies such as in the USA, Britain, Sweden, Canada, Australia, New Zealand, to the newly emerging ones such as Eastern Europe and South Africa. The apparent trend of globalisation is arguably not only confined to the field of public service r

Abstract:
There is no single resource so essential to sustaining life and livelihoods than water (UNDP, 2005). Water is furthermore a strategic resource that not only gives life, but is also a catalyst for development; therefore water has to and must be at the centre of all development plans (Buyelwa, 2009). Water can be the limiting factor for economic growth, upliftment and social development due to its scarcity and uneven distribution. Strategic spatial interface and relationship with water resource planning and management is fundamental to development and realisation of spatial potential. Strategic

Abstract:
Philosophiae Doctor - PhD<br>Water problems prevalent in the Nyando River Basin are due to an ineffective water allocation system and lack of adequate conditions for implementation of sustainable integrated water resources management (IWRM) strategies. The basin is bedevilled by poor water resources management, inequitable allocation of water among consumers, physical infrastructural deficiencies, inefficient water utilisation, illegal water abstractions, natural resource mismanagement, conflicting and weak institutional roles and lack of stakeholder involvement in water resource managem

Abstract:
This thesis develops and validates a comprehensive methodology for measuring sustainability of a large river basin by using a tailored indicator set. The concept of river sustainability concerns not only the ecological condition of the river course, but also socioeconomic activities in the river basin. River sustainability is defined from five perspectives: sufficient resource, resilience to water-related risks, access to water supply and other services, productive use of water, and fairness between different users and generations. The Process Analysis Method (PAM) is employed as the guideline

Abstract:
Under the guidance of the new coastal management policies within South Africa this thesis advocates a more integrated, co-operative approach to local coastal management. The project aimed to acquire baseline information on the local nearshore fishery and resource state and to propose a set of indicators that could be incorporated into the new management strategy. To gather the required information the project was split into two parts: 1) An assessment of the local linefisheries and 2) A comparative study of the reef fish community structure between exploited and unexploited reefs.
