Climate change and variability are increasingly affecting agriculture and livelihoods in developing countries, with India being particularly vulnerable. Drought is one of the major climatic constraints impacting large parts of the world. We examined the effects of drought on crop productivity, evaluated the effectiveness of technologies in mitigating these impacts and quantified the resilience gained due to technology adoption. Resilience score and resilience gain are the two indicators used to quantify resilience. The study utilized data gathered from two villages situated in Karnataka, southern India, which have implemented the National Innovations in Climate Resilient Agriculture (NICRA) program, along with data from one control village. Drought has significantly impacted the yields, and the extent of reduction ranged from 23 to 62% compared to the normal year. Adoption of climate-resilient technologies, including improved varieties, water management and livestock practices proved beneficial in increasing yield and income during drought years. The resilience score of various technologies ranged from 71 to 122%, indicating that the technologies had realized an increase in yields in the drought year in comparison to the normal year. The extent of resilience gain ranged from 7 to 68%, indicating that the adoption of technologies contributed to the yield advantage over the farmers' practice during drought. Water harvesting and critical irrigation have the highest resilience scores and gains, and in situ moisture conservation practices such as trench cum bunding (TCB) have comparable resilience scores and gains. The diversification of enterprises at the farm has a higher resilience score and gain. There is a need to identify climate-resilient technologies that can achieve higher resilience, as the solutions are context-specific. Further, promising technologies need to be scaled by adopting multiple approaches and by creating an enabling environment so as to increase resilience in agricultural systems.
