Asia is the region most vulnerable to climate change and India is ranked as one of the most climate vulnerable countries in the world, frequently affected by natural disasters. In this study, we investigated the impact of drought on crop productivity, farmer’s employment and income. The difference-in-difference model (DID) and stepwise multiple linear regression (MLR) were employed to quantify the impact of adopting climate resilient technologies (CRTs) on farm household income during a drought. The factors influencing farm incomes were analyzed using MLR. The study used survey data collected from the drought prone district of Telangana, India. Sixty farmers each from a village adopted under the National Innovations in Climate Resilient Agriculture (NICRA) program and a control village were interviewed. Primary data on the socio-economic characteristic of farmers, cropping pattern, income composition, productivity of major crops, employment and climate resilient interventions adopted by farmers were collected using a well-structured schedule. The results reveal that income crop cultivation was the major contributor to household income (60%) followed by livestock rearing. Farmers reported that droughts decreased the income from crops by 54 per cent and income from livestock rearing by 40 per cent. The farmers belonging to the climate resilient village had 35 per cent higher incomes compared to those in the control village and it was estimated to be Rs. 31,877/farm household/year during droughts using the DID estimate. Farm size, livestock possession, adoption of CRTs and investment in agriculture were the determining factors influencing farm income. Thus, farmers especially in drought prone regions need to be encouraged and supported to adopt cost effective, location specific climate resilient technologies.

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.

This study conducted to evaluate catchment storage and command relationship and water use strategies under supplemental irrigation for sustainable rainfed agriculture in the semi-arid regions of Rajasthan, India. In southern Rajasthan, a small category of farmers is above 78%, the potential evapotranspiration is greater than the average rainfall with prevailing arid conditions, and rainfed agriculture is a challenging task. An agricultural micro watershed of 2.0 ha evaluated to establish a catchment storage command area (CSC) relationship and micro irrigation system as an effective water use strategy. The significant results indicate that a farm pond with a storage capacity of 560 m³ with permanent lining (cement + brick) is sufficient to harvest runoff water from a 2.0 ha catchment under the rainfall conditions of below normal (up to 50% deficit), long-term average, and wet years. Harvested rainwater can be used to irrigate a command area of even up to 1.0 ha, with supplemental irrigation of 5 cm in both the seasons of kharif as well as rabi. The two crops, maize (Zea mays) in the kharif season and coriander (Coriandrum sativum) in the rabi season, were significantly profitable with supplemental irrigation by adopting a drip irrigation system.
