In order to protect the biodiversity and the depleted marine resources, we should reserve them for future generations.Therefore, try to introduce the concept of Marine Protected Areas ( MPAs) which are based on ecosystem. It is divided into different kinds of protected areas to reserve the resources and protect the biodiversity and the completeness of natural habitats. MPAs offer the foundation of natural Sustainable Development. According to this research, and use the theory of resource economics basis to discuss the effective of MPAs. Then, it continued to discuss the effective of MPAs which is under negative uncertainty. According to the evidence of results, MPAs indeed can reap the benefit of our ecological at the same time , it also can maintain the effectiveness of MPAs.

This is a talk prepared for The Bahamas At 40: Reflecting On The Past, Envisioning The Future Conference. This talk will be given in a session entitled: Small Island Sustainability on June 13, 2013.

There is a lack of tools for zoning marine protected areas (MPAs). MARXAN is a popular tool for MPA siting, and this thesis explores its use for zoning. MPA managers and zoning practitioners were interviewed in order to determine the requirements of zoning. This, combined with a literature review, informed the testing of several MARXAN settings. This testing was necessary due to poor existing documentation and the uncertainty associated with many settings. Finally, different methods for creating and combining zones were also developed. Due to the complexity of MARXAN it is not possible to develop specific guidelines for many of the settings tested in this research. However, general trends for several settings were determined, and applied within the context of MPA zoning. Preliminary zones were developed and combined using MARXAN’s summed solution output, the results of which are ready for zone refinement with stakeholders and MPA planners.

Ecotourism has emerged as one of the fastest- growing sectors of the tourism market, influenced primarily by public demand for more environmentally responsible tourism. When planned properly, it has been asserted that ecotourism can integrate conservation of biodiversity with socio-economic development of local communities. For this reason, many governments and non-governmental organizations (NGOs) are eager to develop ecotourism in protected areas in order to maximize these benefits. However, ecotourism can have significant negative impacts when poorly planned and managed including severe environmental degradation, negative cultural changes and decreased welfare of individuals or communities. Ecotourism should not be regarded as a panacea for harmonizing rural development with environmental conservation until the industryâ s influence on developing countries has been thoroughly analyzed. This paper shall explore whether ecotourism has proven to be an effective tool for integrating conservation and development. Through the examination of existing literature pertaining to ecotourism, I investigate the environmental, economic and social impacts of 14 ecotourism development projects in seven developing countries: Belize, Costa Rica, Dominica, Ecuador, Indonesia, Nepal and Peru. The case study analysis reveals that local communities adjacent to protected areas are often not fully involved in the tourism development planning process. Ecotourism as a mechanism for achieving local conservation and development goals is more successful when projects prioritize local involvement and control. Through the identification of trends emerging from the case studies, this paper contributes to the ongoing discussion of ecotourism as a development strategy and suggests that local participation should be encouraged in ecotourism development. / Master of Urban and Regional Planning
