International research on natural resource management: advances in impact assessment.

Book cover for International research on natural resource management: advances in impact assessment.

Description

This book is addressed to scientists, researchers, development specialists and policy makers who deal with natural resources and agriculture in the developing countries. It aims to (1) provide evidence of the impact of natural resource management research (NRMR) in the CGIAR; (2) establish a methodological foundation for impact assessments of NRMR; and (3) draw up a set of lessons for future impac...

WorldFish Centre. Impact of the development and dissemination of integrated aquaculture-agriculture technologies in Malawi.

This chapter presents an ex post impact assessment of the development and dissemination of small-scale integrated aquaculture-agriculture (IAA) technologies in Malawi over more than 15 years by the WorldFish Centre and its national and international partners. The results indicate that the adoption of IAA technology in Malawi has improved total farm productivity by 10%, increased per hectare farm income by 134% and total farm income by 61%, and improved the technical efficiency of farming by almost 40%. In addition, the increased per capita consumption of fresh fish by about 208% and per capita consumption of dried fish by about 21% have resulted in an enhanced consumption of protein-rich foods. IAA has improved the sustainability and environment of the adopters' farms, reduced nitrogen loss by half and improved nitrogen use efficiency. The development and dissemination of IAA technologies in Malawi have also institutionalized the natural resource management approach within the Malawi Department of Fisheries, strengthened local institutions and improved the overall welfare of both producers and consumers. The internal rate of return from research and dissemination of IAA technologies in Malawi is at least 12.2%. This estimated rate of return is a very conservative estimate and does not include many of the positive non-market benefits of IAA technology such as impact on ecosystem health and local institutions.
