This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends developing environmentally sound aquaculture technology that is compatible with local, regional and national water resources management plans and takes social factors into consideration. Such strategies should include environmental management in support of rural fish-farming communities.
Fisheries production is closely tied to man's treatment of the environment. The effects of pesticides and high siltation rates from agriculture and urban developments have caused the declines of many fisheries around the world. Most historical fisheries are at or beyond their maximum sustainable yield. However, some gains in production can be obtained from revitalizing natural systems and habitats. This can only be done by managing the environment, and man's activities relative to his environment, and following the concepts of sustainability. This may require preservation zones adjacent to natural waterways, runoff collection ponds below agriculture and urban development, control of the use of pesticides and herbicides, and other control measures.
