This report presents the results of studies undertaken for incorporating low-external input aquaculture practices into the farming systems of a complex floodprone ecosystem in Bangladesh and the impacts of integration on income, nutrition and resource use in rural households. The study shows that multi-purpose ponds which were underutilized or unutilized because of risk of flooding could be made productive through proper management and incorporation into the existing farming systems. Farmers with minimal external inputs were able to increase fish production and consumption by 5 to 8 times.
