Abstract

Sustainable agricultural intensification is an urgent challenge for Sub‐Saharan Africa. One potential solution is to rely on local farmers' knowledge for improved management of diverse on‐farm resources and integration among various farm enterprises. In this article, we analyze the farm‐level impact of one recent example, namely the integrated aquaculture–agriculture (IAA) technologies that have been developed and disseminated in a participatory manner in Malawi. Based on a 2004 survey of 315 respondents (166 adopters and 149 nonadopters), we test the hypothesis that adoption of IAA is associated with improved farm productivity and more efficient use of resources. Estimating a technical inefficiency function shows that IAA farms were significantly more efficient compared to nonadopters. IAA farms also had higher total factor productivity, higher farm income per hectare, and higher returns to family labor.
