“…Kumar et al (2015) concluded in their study that scientists concurred with the fact that climate changes ushered in additional stress on the already fragile systems of agriculture as well as affected crop physiology. Changes in temperature and precipitation may either benefit or harm agricultural systems depending on the location in the world (Chavas et al, 2009, Ruane et al, 2013, Mishra et al, 2013. Climatic parameters such as solar radiation, temperature, moisture, rainfall etc.…”

Impact of climate change on crop yield threatens food security which is detrimental to agricultural sector. Cachar district of Assam is a climate susceptible district due to its unique geographical location and hydrological regime in north-eastern India. So, the present study was carried out to assess impact of climate change on crop yield for sustainability of agriculture. Climatic data viz., rainfall, maximum-minimum temperature and sunshine hours were collected from an observatory of Tea Research Association, Silcoorie, Cachar district for 2007-2012. Statistical and correlation analysis was employed to evaluate potential climate change impact on productivity of twenty three major crops of the study site. The correlation coefficient (r, Pearson's Product Moment) between any climatic parameter and crop yield implied that climate has strong linear correlation with yield of crops resulting in twenty-two strong correlations. Among the climatic parameters rainfall was found to have most significant impact on yield. Noteworthy reduction was observed in yield of Autumn .89%, respectively. The study revealed that climate change has significant impact on crop yield which could be alleviated by adopting rainwater harvesting technology at the top and foot hills of the hilly areas.

“…Irrigated rice is likely to suffer yield loss up to 23 % in regions which are expected to receive more rainfall. Literature regarding the macro level impact of climate change using predictive and/or simulation modelling [9][10][11][12] is galore, but the present study is an addition to the methodology and develops an approach to investigate into the crop yield sensitivity at the micro level ( Fig. 1).…”

“…Trend analyses in literature using historical yields data of long term fertility and conventional field experiments, and crop simulation models indicated that declining rice yields in the Indo-Gangetic plains (IGP) may be partly due to the gradual change in weather during the past two decades [10,21]. Similarly, in Karnal district, area-productionyield showed a clear oscillation for both the crops.…”

“…Anomalies in the weather variables cause some changes in the crop phenology that significantly affects the yield [21]. Rice yields decreased from the west to east in the IGP, whereas, wheat yields appeared to be increasing throughout the IGP [10]. Also, there exists a possibility for a production loss of 4-5 million tonnes in wheat for every 1°C rise in mean temperature during the growing period [21].…”

Climate change impacts agriculture, food production and security in view of a region's geography, monsoon dependency and weather extremities. Yield sensitivity to the anomalies of weather is an emerging issue in the perspective of climate smart farming. The present study develops an approach to assess the yield sensitivity of ricewheat cropping system using a non-parametric MannKendall's test for examining the long-run weather anomalies between 1981 and 2013, followed by regressing yield (stepwise) on weekly weather variables. This approach confirms the long-run weather anomalies and then proceeds to identify the sensitive weeks for climate smart practices, and adaptation strategies for drawing policies. A significant long-run trend has been noticed in the weather variables barring rainfall in rice growing season and evapotranspiration in wheat growing season.Stepwise regression indicated that rice yields are positively influenced by minimum temperature during its growth week 13, evapotranspiration in week 15 and wind speed in week 10; and wheat yields are sensitive to the maximum temperature and evapotranspiration in week 1, as well as sunshine hours in week 6. Volatility in weather variables during ripening in rice and crown root initiation and late tillering in wheat reduces the yield. The interactive effect of significant weather variables on rice and wheat yield indicated its sensitivity due to the weather anomalies in varying magnitudes. This approach is ideal to measure the sensitivity in crop yield owing to anomalies in disaggregated weather variables. Further, it warrants suitable and relevant policy recommendations. In our case, the future research should focus on developing agro-climatic region specific rice and wheat genotypes resilient to climate change, identifying climate smart farming practices as well as adaptation strategies.

“…Many researchers have used DSSAT for analysis of climate change impacts on rice-based production system in India (Subash and Ram Mohan 2012;Mishra et al 2013). Satapathy et al (2014) simulated the possible climate change impacts using HadCM3 data and found a continuous decline in the rice grain yield for the years 2020, 2050 and 2080 with increasing temperature >0.8°C.…”

With the rise in population, under future scenarios, global food demand is expected to increase. Biotic and abiotic factors such as climate change are threat to food security owing to its variability, occurrence, duration and magnitude of extreme events. Since, the climate change is unequivocal, the adaptations and mitigations for sustainable agricultural production can minimize its negative impact on agriculture and improve food grain productivity. The grain yield of rice and peanut was simulated for the base period (
