Rice-fish integration for high saline, coastal areas of Bangladesh: Learning from the Challenge Program for Water and Food (CPWF)

Abstract

The Southwestern coastal zone of Bangladesh is agro-based and one of the world's most populous, poverty-stricken and food-insecure regions, with high vulnerability to climate change. Shrimp aquaculture rapidly expanded in this tidal floodplain but shrimp is highly susceptible to disease, has less contribution in local consumption, and its profitability depends on international market prices, leading the demand for improving the farming system. There is an opportunity to diversify and increase system productivity by integrating rice with aquaculture during the monsoon season through adoption of some water management practices at an individual and community level. This also minimizes the effluent load of aquaculture intensification.
