DP8940 Transfers, Diversification and Household Risk Strategies: Experimental evidence with lessons for climate change adaptation
While climate change is likely to increase weather risks in many developing countries, there is little evidence on effective policies to facilitate adaptation. This paper presents experimental evidence on a program in rural Nicaragua aimed at improving households? risk-management through income diversification. The intervention targeted agricultural households exposed to weather shocks related to changes in rainfall and temperature patterns. It combined a conditional cash transfer with vocational training or a productive investment grant. We identify the relative impact of each complementary package based on randomized assignment, and analyze how impacts vary by exposure to exogenous drought shocks. The results show that both complementary interventions provide full protection against drought shocks two years after the end of the intervention. Households that received the productive investment grant also had higher average consumption levels. The complementary interventions led to diversification of economic activities and better protection from shocks compared to beneficiaries of the basic conditional cash transfer and control households. These results show that combining safety nets with productive interventions can help households manage future weather risks and promote longer-term program impacts.
