Yashodha (IWMI) presented the design of an impact evaluation of the SKY (Suryashakti Kisan Yojana) program in Gujarat, India. The program supports the generation of solar electricity by farmers for their own consumption (irrigation) as well for selling back to the grid and generating additional incomes. Guanghong Xu (UCSC/ILRI) presented a randomized controlled trial evaluating the effect of a demand aggregation intervention (in which farmers are encouraged to vaccinate together) cross-cut with a “checkoff system” intervention (in which a percentage of milk sales is set aside at milk cooperatives to be allocated for vaccine purchase) on the adoption of ECF vaccine in 80 dairy cooperatives in Kenya.
