Sustainable yield in coastal zone and aquatic ecosystems

In this paper, I intend to identify both issues and problems faced in extracting yields from coastal zone environments. The issues are certainly ecological, but they are equally social, anthropological, and economic. The scope of the paper is wide enough to encompass the production of usable protein from inland aquatic sources such as rivers, lakes, and aquaculture facilities. The theme that emerges will center on the conceptual and operational reasons why coastal zone and aquatic ecosystems should be included as one of the "key agro-ecosystems facing critical poverty and environmental constraints." An ecosystem perspective that has adaptive management as a conspicuously built-in component will be advocated. (author)
