“…The farmland which has better adaptation and less variation in the climate factors reduces the damage caused by the rise in temperature. The past studies that focus on estimating the effect of climate change on dryland cultivation have indicated larger damage when compared to irrigated land cultivation (Kalli and Jena, 2020;Schlenker et al, 2007). The present study supports the…”

“…In addition, significant increasing trend in the maximum and minimum can be noted. As a result, controlling for other factors of input, climate variables have a negative impact on farm income and crop productivity (Mall et al, 2006;Kumar, 2011;Kalli and Jena, 2020). Seo et al (2009) analyzed the impact of climate change on Sri Lankan agriculture using the Ricardian technique.…”

PurposeClimate change is the most concerned issue in the global economy; increase in climate variability and uncertain climate events have caused distress in agriculture sector. The study estimates economic effect of climate change on agriculture income for the Indian state of Karnataka. The study reports the difference of result from past studies, where estimates from present study indicate higher negative impact of rise in temperature.Design/methodology/approachFixed effect panel regression method was used to examine change in agriculture revenue to climate response. Climate variables were classified based on the crop calendar to capture the damage caused by climate change. The authors use fine scale climate data set constructed at regional context for 20 districts and time period of 21 years (1992–2012).FindingsThe result showed that with 1-degree rise in average maximum temperature, the revenue declined by 17–21%. The prediction behavior of the different models was evaluated using out-of-sample forecast approach by training and testing historical data set.Originality/valueThe study adopts recent data sets on agriculture and the updated climate variables to estimate the climate change impact on agriculture. The study yields the better results when compared to previous traditional models applied in literature in Indian context. The study further evaluates the prediction behavior and robustness of the estimated models using out-of-sample forecast method.

“…Similarly, rise in temperature alters the photosynthetic rate and inhibits plant growth, which, in turn, decreases the total agriculture production. In arid regions, where higher temperature pre-exists, a small rise in temperature will have a stronger negative impact on plant growth (Schlenker & Lobell 2008;Kalli & Jena 2020). To represent the climate change of the region, we used six indicators to construct the exposure sub-indextwo indicators of rainfall and four indicators of temperature.…”

Climate change vulnerability is highly counter-productive for agriculture among the arid and semi-arid regions. The study constructs the agriculture vulnerability index for the semi-arid regions of Karnataka, a south Indian state. The state has faced frequent climate-related shocks in the last decade. The district-wise vulnerability index is estimated using longitudinal data considering exposure, sensitivity and adaptive capacity of the districts to climate variations as sub-indices. The results show that the districts in the north interior region of Karnataka are highly vulnerable to the climate change followed by the districts in the south interior and coastal regions. There is an urgent need to prioritize the most vulnerable districts while formulating the development policies to minimize the risk of climate change on agriculture. Specific technical knowledge and support need to be made available to the farmers for informative climate resilience action.

“…In 2016, about 14 lakh people from Mahabubnagar, Ranga Reddy, Medak, and Nizamabad migrated to Hyderabad and other cities like Pune, Mumbai, and Ahmedabad, as mentioned in the report of farmers organizations [5]. Hence, climate extremes pose a serious threat to crop yields, food security and farm income Kalli and Jena [6,7]. Effectively addressing climate change in agriculture requires a comprehensive strategy, with the focal point being a transition toward agricultural practices resilient to climate variations.…”

Climate change is a challenge for developing countries like India due to climate variability. The study area of Telangana is also prone to frequent droughts, resulting in distress among farming communities, and witnessed crop failures leading to farmer’s suicides. The State Action Plan on Climate Change (APCC) reported these issues of drought and heat waves in agriculture. Therefore, the present study was undertaken in 2017-18 by using an ex-post facto research design to assess the climate resilient technologies, mitigation strategies adopted here, and their influence on farm income among the already ascertained most vulnerable Mahabubnagar district and least vulnerable Khammam district farmers of Telanagana State. A total of 480 respondents, 240 from each district, were selected randomly. The technology adoption index was constructed to ascertain the extent of adoption of climate-resilient technology, and further study analyzed the factors influencing the adaptation of climate- resilient, technologies such as the technology adoption index on household farm income, along with other factors. The results of the study indicated that different strategies adopted by farmers in mitigating climate change, such as use of drought-tolerant varieties and life saving irrigations had a positive influence on adaptation to climate change. Further, the study reported that the technology adoption index (TAI) showed a positive, non-significant impact on farm income in both scenarios considered i.e. Mahabubnagar and Khammam which implies that there needs, adopting more technologies intensively and timely, have to significant influence on farm income.
