“…A systematic review of simulation models by Mall, Singh, Gupta, Srinivasan, and Rathore () shows a clear deterioration in yields of principal cereal crops such as maize, wheat, and rice under weather change. Soora et al () studied the effect of climatic factors on regional rice production of the 21st Century in India. They reported that the rice yield of rainfed in India is probable to be declined 6% in the 2020s scenario.…”

The present study explores the effect of climate change on maize yields and its variance in Telangana utilizing Just–Pope production function, spanning the period 1956–2015. The three‐step feasible generalized least squares (FGLS) method is employed to estimate the Just and Pope production function. The empirical results of the work reveal that the average minimum temperature has a significant unfavorable effect on maize yield in Telangana. Maximum temperature and actual rainfall are positively related with maize yield; however, the maximum temperature is not statistically significant. Furthermore, rainfall and minimum temperature are risk‐shrinking factors, but the maximum temperature is a risk‐enhancing factor for maize yields during the study period. The study results have key implications for developing suitable local level adaptation policies in Telangana.

“…Surprisingly, very few studies over India have been focused on understanding the land-atmospheric nexus of agriculture, climate, hydrology and socioeconomics. For example, a study by Soora et al [18] used the InfoCrop-Rice model to identify the vulnerable regions for irrigated and rainfed rice cultivation, and further quantified the impacts and adaptations associated with future climatic scenarios in India. Nonetheless, this study primarily attempted to associate the response of crop yield to climate variables for estimating vulnerabilities and less emphasized on regional socio-economics.…”

Indian agriculture is globally well-documented to reflect the impacts of changing climate significantly. However, climate adaptation efforts are often hindered due to the inadequate assessment of coupled human-environment interactions. In this study, we propose a novel unified country-level framework to quantify the decadal agricultural risks derived from multiple hydro-meteorological exposures and adaptive consequences. We identify, for the first time, that rice and wheat risks have increased in the recent decade, with wheat at a twofold higher magnitude than rice. Increasing crops risk is found to be predominantly driven by the decreasing number of cultivators; in particular, the wheat risk is also attributed to increasing minimum temperatures during the crop growing season. We provide convincing evidence indicating that the hydro-climatic hazards related to precipitation extremes and droughts are specifically alarming the crops risk as compared to temperature extremes. These observation-based results highlight the sensitivity of India's agriculture and the risk associated with multiple agro-ecological and climatic components. We recommend these findings to facilitate the informed planning of adaptive measures and ensure sustainable food security of the nation.

“…Kumar et al (2004) clarified the influence of monsoon rainfall on the production of five major crops based on state-level statistics. Soora et al (2013) adopted the SRES scenarios to predict the impact of climate change on rain-fed rice yields in five regions covering several states. Given India's diverse topography and climate, conducting analyses using state data is expected to reflect actual conditions better than when using national data.…”

Climate Change Effects on Supply and Demand of Rice in India production and cultivation areas are greater than those of other crops. And since 2012, India has overtaken Thailand as the world's largest rice exporter. In 2013, India's share of world rice exports was 30.1% and subject to wide fluctuations according to domestic production. The share of total exports to the total production of rice in the world was only 6.0% in 2013. Therefore, the world rice market is relatively small compared to the domestic rice market, and India's rice production strongly affects the world food market. Rice in India is grown mainly in irrigated and rainfed areas. In the total rice area, the respective percentages of irrigated, rain-fed, and flood-prone rice areas are about 49.5%, 45.9% and 4.6%, respectively (Directorate of Rice Development 2014). In particular, rice production in rain-fed areas is highly sensitive to climate conditions. Goswami et al. (2006) detected two abnormal climatic phenomena in India: (1) considerable increases in the frequency and magnitude of extreme rain events, and (2) marked decreases in the frequency of moderate events over central India during the
