ATAI evidence synthesis discussion
Weather index insurance protects farmers against losses from extreme weather and facilitates investment in their farms, but randomized evaluations have shown low demand for these products at market prices suggesting the need for alternative approaches.
This page summarizes ATAI’s policy bulletin on the impact of weather index insurance, “Make It Rain” and ATAI’s policy briefcase on the impact of Swarna-sub1, “Resilient Rice.” It was written by ATAI staff, originally published on the J-PAL website at this link.
Floods, droughts, heat waves, cold spells, and other natural disasters are large sources of risk for farmers. A drought, heat wave, or other disaster can lead to a poor harvest, leaving uninsured farming households with little income for the season. In order to cope with unpredictable weather, farmers often plant low-risk, low-return crops instead of investing in more profitable crops that are more sensitive to weather. Furthermore, farmers wary of bad weather may hesitate to make other investments in their farms, such as increasing fertilizer use. As a result, the threat of extreme weather can trap farmers in a cycle of low productivity.
Weather index insurance, which makes payouts based on an easily observable variable such as rainfall, is an innovative financial product designed to make insurance accessible to poor smallholder farmers. Weather index insurance was first offered in the early 2000s, and it is now marketed to individual farmers in over fifteen countries. The ten randomized evaluations summarized in “Make it Rain” tested take-up of weather index insurance products and, in three cases, effects on agricultural production decisions.
Large discounts increased take-up substantially and interventions designed to increase financial literacy or reduce basis risk also had positive effects. However, at market prices, take-up was in the range of 6–18 percent, which cannot sustain unsubsidized markets.
In the three studies that measured changes in farmer behavior, farmers who felt protected against weather risks shifted production toward crops that were more sensitive to weather but more profitable on average.
Weather risk remains an important barrier to agricultural development. Although low demand has prevented markets for commercial weather index insurance from scaling, in cases where farmers were given subsidized insurance, the protection led them to make investments to increase farm productivity. These facts point to the need to study a range of alternative approaches to address weather risk.
Many insurance providers rely on generous government subsidies, technical assistance from aid agencies, or bundling insurance with more popular products.
They shifted production toward crops that were more sensitive to weather but more profitable on average. Whether through index insurance or another approach, providing protection against weather risk may be a crucial step in getting farmers to plant cash crops, use more fertilizer, and make other investments to increase production.
This points to the need to research alternatives that help smallholder farmers manage weather risk, including:
This evaluation took place in Odisha, India in 2011 and 2012.
While self-sustaining markets for weather index insurance have not emerged, finding ways to address weather risk remains a priority for agricultural development. One promising alternative is to explore other risk-mitigating technologies, such as improved seeds that better tolerate weather events. Crop varieties that reduce losses during flooding or droughts and maintain yields during normal years may be more appealing to farmers than insurance while still allowing households to take on more risk in decisions such as input purchasing. These are breeder-selected varieties of common seeds that maintain high yields if a drought or flood occurs.
Swarna-Sub1 is one example of a resilient breeder-selected variety and was developed by researchers from the Consultative Group on International Agricultural Research (CGIAR). To create Swarna-Sub1, CGIAR inserted a flood-resistant gene called Sub1 into the popular Swarna rice variety. Swarna-Sub1 is nearly identical to Swarna, the most popular rice variety in India, but can tolerate submergence for up to two to three weeks without the flood conditions affecting yields.
Access to Swarna-Sub1 seeds reduced losses in yields by an average of 10 percent per hectare with even greater losses among farms that experienced more days of flooding. In areas without flooding, there was no significant difference in yield between the two varieties, indicating that there was no disadvantage to planting Swarna-Sub1 in non-flood years.
In addition, because Swarna-Sub1 is highly similar to Swarna, with which many farmers in India are familiar, switching to Swarna-Sub1 does not require significant changes in behavior or an extensive information campaign—a sharp contrast with more complex innovations designed to address risk, such as weather index insurance.
Swarna-Sub1 protected against the risk of unpredictable flooding, so farmers had less need to self-insure by making conservative planting and investment decisions. This resulted in a number of changes to farmer behavior including cultivating additional land, increasing investment in inputs, adopting improved planting techniques, and changing savings and credit decisions. These investments led to higher rice yields even when no floods occurred. This suggests that risk-reducing seeds have additional benefits beyond those that accrue during weather shocks because they can lead farmers to make more productive investments in their farms.
Scaling up Swarna-Sub1 to flood-prone areas would benefit marginalized farmers the most. In India, members of Scheduled Castes or Scheduled Tribes tend to cultivate low-lying, flood-prone land and would therefore likely experience the greatest yield improvements from the adoption of flood-tolerant rice. To the extent that marginalized groups around the world tend to farm less desirable pieces of land, the development and adoption of weather-tolerant crops could help mitigate the effects of entrenched inequalities.
