Abstract

Conservation agriculture, drought tolerant maize, and improved legume varieties are key climate change management strategies for smallholder farmers in southern Africa. Their complementary efforts in adaptation to climate change are sternly important for farm productivity and income. This study evaluates factors explaining individual and multiple adoption of climate change management strategies and their differential impacts on productivity and income using a sample of 1172 smallholder farmers from Malawi and Zimbabwe. The study employs multinomial logistic regression to evaluate factors of individual and multiple adoption and regression adjustment with inverse probability weighting to evaluate impacts of the different adoption regimes on farm productivity and income. The results show that multiple adoption of innovations is mostly explained by access to key resources (credit, income and information), level of education and size of land owned by the farmer. More so, the concurrent adoption of conservation agriculture, stress adapted legume varieties and drought tolerant maize has far greater dividends on productivity and income than when considered individually. However, impacts of multiple adoption of the practices are not entirely uniform across different geographic regions and gender. Results suggest that effective institutional and policy efforts targeted towards reducing resource constraints that inhibit farmers' capacity to adopt complementary climate-smart agriculture packages such as conservation agriculture, drought tolerant maize and improved legume varieties must be gender sensitive and context specific.
