Abstract
An incremental, farmer participatory approach to the development of sustainable aquaculture in integrated farming systems has been tested in Malawi. Average fish production rose from 900 to approximately 1500 kg ha-1 as farms achieved increasing levels of integration. Integrated farms produce almost six times the cash generated by the typical Malawian smallholder. The integrated pond-vegetable garden generates almost three times the annual net income from the staple maize crop and the homestead combined. The ecological footprint of integrated aquaculture is approximately 4 m2 per kg of fish produced compared to 170 m2 for more intensive systems. The incremental approach offers the possibility of fostering substantial improvement in rural livelihoods among African smallholding farmers.
