Conservation Agriculture and Climate Resilience(2016)
Climate change is predicted to increase the number and severity of extreme rainfall events, especially in Sub-Saharan Africa. In response, development agencies are encouraging the adoption of ‘climate-smart’ agricultural techniques, such as Conservation Agriculture (CA). However, little rigorous evidence exists to demonstrates the eﬀect of CA on production or climate resilience, and what evidence there is, is hampered by selection bias. Using panel data from Zimbabwe, we test how CA performs during extreme rainfall events - both shortfalls and surpluses. We control for the endogenous adoption decision and ﬁnd that while CA has little, or if anything, a nega-tive eﬀect on yields during periods of average rainfall, it is eﬀective in mitigating the negative impacts of rainfall shocks. Farmers who practice CA tend to receive higher yields compared to conventional farmers in years of both low and high rainfall. We conclude that the lower yields during normal rainfall seasons may be a proximate factor in low uptake of CA. Policy should focus promotion of CA on these climate resiliency beneﬁts.
