Shrimp-rice farming practices in the coastal areas of Bangladesh and West Bengal, India are reviewed. It is apparent that this integrated aquaculture-agriculture system is suited to environmental and hydrological conditions found in specific areas. Production strategies devised by farmers demonstrate that the diversified culture of shrimp with rice is technically feasible. Shrimp-rice agroecosystems exhibit several synergistic effects between systems components that result in efficient resource use and enhanced production, whilst avoiding negative environmental impacts. Integrated cropping enhances agrobiodiversity and reduces dependence on external inputs (agrochemicals, feed and fertiliser). Diversified shrimp-rice culture produces a valuable export crop, stimulating economic development and staple cereal, fish and vegetable crops that enhance human nutrition and food security. The contribution that diversified shrimp-rice agroecosystems make to social-ecological resilience is evaluated using the DPSIR (Driving forces, Pressures, State, Impacts, Responses) framework. Strengths, Weaknesses, Opportunities and Threats (SWOT) associated with prevailing practices are reviewed using the SWOT framework. We conclude, that with appropriate safeguards, diversified shrimp-rice agroecosystems could contribute to climate change adaptation and enhance production from land affected by salinization. Policy-support and practical action is needed to support and promote diversified shrimp-farming agroecosystems as they can contribute to social-ecological resilience in vulnerable coastal communities.
