Climate change increases the intensity and frequency of extreme weather events. Smallholder farm households in the Global South that depend on weather conditions for their living are particularly affected. Not only are those households more geographically exposed to extreme weather events, but they are also less resilient when hit by such shocks. With climate change progressing rapidly, there is a pressing need to provide effective adaptation instruments that assist farm households in the Global South in adapting to increasingly extreme weather conditions. Parametric insurance (also referred to as index-based or trigger-based insurance) is a market-based adaptation instrument aimed at increasing the climate resilience of farm households. Policyholders receive insurance payouts whenever an index, such as rainfall or temperature, defined at an aggregated geographical level exceeds or falls short of a predefined threshold. If an extreme weather event occurs, insurance payouts are expected to help households recover faster from the shock-induced damages. Since the late 1990s, parametric insurance has been piloted in low- and middle-income countries globally. Most of these programs struggle with low take-up rates. To better understand the barriers to demand for agricultural (parametric) insurance, the German Institute for Development Evaluation (Deval) will fund the impact evaluation of a Trigger-Based Agricultural Micro Insurance in Vietnam, aiming at increasing the climate resilience of smallholder farmers. The research project aims to implement multiple survey rounds of a panel survey among rice farmers in the Mekong Delta region. The project aims at providing new and methodologically rigorous evidence on the following research questions: (1) Does access to parametric agricultural insurance in Vietnam enhance households’ resilience? (2) Do premium discounts encourage insurance uptake among farm households? (3) Does training on product understanding encourage insurance uptake? (4) Does providing farm households with access to climate projections encourage insurance uptake?
