This talk seeks to address a key challenge in aquaculture development policies, which is the paradox of economic efficiency, social considerations, and environmental conservation. By examining data obtained from a household survey in Vietnam, Dr. Chu's study finds that mangrove aquaculture, if properly designed, can be a triple-win approach. The data showed that mangrove aquaculture offers the highest rate of return compared to other types of aquaculture farming, while requiring only a modest up-front investment, which is well-suited for the poor people. The data deduced that the best rate of return would be achieved if mangrove coverage were to be maintained at around 60%. This finding supported the view that there is no direct need for a trade-off between economic efficiency and environmental conservation. It differed from the common view of farmers that aquaculture farming would be more profitable with lesser mangrove. This indirectly improved the sustainability factor of food production in such ecosystem. Dr. Chu's findings provide important implications for aquaculture policies in developing countries and emphasize the importance of complementary programs, such as awareness enhancement and training, toward sustainable development objectives.
