Management of rainfed aquaculture on Malawian smallholdings

Traditional pond construction and aquaculture technologies mandate the exploitation of limited water resources. The result is often a lowering of water qualilty and quantity available for alternative uses and users. Rainfed ponds might offer a non-polluting alternative, and make fish farming feasible for a wider variety of potential adopters. Microclimatic effects of holding water on the land might also create positive environment impacts on the farm itself, and over a larger area if widely implemented. A pilot study of the technical and economic feasibility of small scale rainfed aquaculture found that these systems can be both profitable and self-sustaining in rural Malawi. In addition, mechanisms which might generate long-term environmental benefits (e.g. improved fertility, soil drainage, crop production and soil moisture), were found to function effectively even in the short term.
