Purpose Farmers' adaptation strategies in agricultural production are required to minimise the negative impact of climate change on a nation's food production in developing countries. Based on the panel data of the provincial level in China from 2000 to 2017, this study aims to analyse the changing climate over recent years and farmers' adaptation strategy in terms of cropping in agricultural production. Design/methodology/approach This study uses Simpson's diversity index (SDI) to measure the degree of crop diversity planted by farmers and evaluate the influence of climate change on farmers' cropping strategy using the fixed-effect model. Further, the authors estimate the impact of farmers' cropping strategy on their economic performances in two aspects including yields and technical efficiency of crops. Findings The empirical results show that the overall climate appears a warming trend. Different from farmers in some other countries, Chinese farmers tend to adopt a more specialised cropping strategy which can significantly improve the technical efficiency and yields of crops in agriculture. In addition, as a moderating role, the specialised cropping can help farmers to alleviate the negative impact of climate change on technical efficiency of their crops. Originality/value First, previous studies showed that the changing climate influenced farmers' adaptation strategies, while most studies focussed on multiple adaptation strategies from the farm-level perspective rather than cropping strategy from the nation-level perspective. Second, the present study investigates how the cropping strategy affects the economic performance (in terms of the technical efficiency and crop yields) of agricultural production. Third, the stochastic frontier analysis method is used to estimate the technical efficiency. Fourth, this study explores the moderating effect between farmers' cropping strategy and technical efficiency by introducing an interaction item of SDI and accumulated temperature.

<p><strong>Abstract.</strong> Climate change induced extreme weather events such as drought and flood condition are likely to become more common and associated impacts on crop production will be more without proper irrigation planning. The present investigation was undertaken for assessing the impact of Climate change on tomato yield and water use efficiency (WUE) using AquaCrop model and RegCM 4.4 simulations. The water driven AquaCrop model was validated based on observation of field experiment conducted with four different dates of sowing (1st November, 15th November, 1st December, 15th December) at Ponnaniyar basin, Tiruchirappalli. Validation of AquaCrop model indicated the capability of AquaCrop in predicting tomato yield, biomass and WUE close to the observed data. Seasonal maximum and minimum temperatures over Tiruchirappalli are projected to increase in the mid-century under both RCP4.5 and RCP8.5 scenarios. Maximum temperature is expected to increase up to 1.7&amp;thinsp;&amp;deg;C/2.5&amp;thinsp;&amp;deg;C in SWM and 1.9&amp;thinsp;&amp;deg;C/2.9&amp;thinsp;&amp;deg;C in NEM by the mid of century as projected through stabilization (RCP 4.5) and overshoot emission (RCP 8.5) pathways. Minimum temperature is expected to increase up to 1.6&amp;thinsp;&amp;deg;C/2.2&amp;thinsp;&amp;deg;C in SWM and 1.6&amp;thinsp;&amp;deg;C/2.1&amp;thinsp;&amp;deg;C in NEM by the mid of century as projected through stabilization (RCP 4.5) and overshoot emission (RCP 8.5) pathways. Seasonal rainfall over Tiruchirappalli is expected to decrease with RCP4.5 and RCP8.5scenarios with different magnitude. Rainfall is expected to change to the tune of &amp;minus;1/&amp;minus;11 per cent in SWM and &amp;minus;2/&amp;minus;14 per cent in NEM by the mid of century as projected through stabilization (RCP 4.5) and overshoot emission (RCP 8.5) pathways.</p>

The Impact

India has shown high vulnerability towards the impact of climate change due to thedependency of 58 per cent of India’s population on agriculture. The study was carried on180 respondents in three districts selected randomly of eastern Uttar Pradesh to evaluatefarmer-led adaptation strategies to the impact of climate change, activities that arepredominantly led by farmers to make them more adaptable to long-term changes in weatherpatterns. All the respondents had experienced extreme climatic events in the last 5-10 years,making the region climate-prone. Nine farmers’-led adaptation strategies to climate changefollowed in crop farming were documented and quantified by using Climate ChangeAdaptation Index. Adaptation strategies were evaluated using the Quantification ofIndigenous Knowledge method (QuIK) method; by involving the key informants followedby peer farmers. Crop diversification, use of high yielding varieties of crops andpreparations of bunds to control water flow were the most preferred adaptation strategiesto climate change. The irregular rainfall increased the incidence of floods in eastern UttarPradesh; thus, the preparation of bunds to regulate water flow in crop fields was the mostefficient adaptation strategy.

Climate change is now a reality. Agriculture in India is likely to suffer losses due to heat, erratic weather and decreased availability of irrigation. Adaptation strategies can help minimize the impact. But that will come at a cost although not still accurately measurable and is likely to be high. This also requires new policy support, research and investment. However, cost of inaction will be still higher. Carbon dioxide level is now about 400 ppm which is likely to increase to about 450 to 600 ppm during 2050 and by 2100 it is likely to go up anything above 500 ppm to 1000 ppm if current situation is allowed to continue. This paper attempts to analyse the impact of climate change on Indian agriculture in terms of decreased productivity to be seen in relation to increase in population. And to counter that impact what are the measures being initiated.

This study addressed the awareness, perceptions and adaptation strategies undertaken to cope up with the impact of climate change, by the women in Versova urban fishing village, Mumbai in Maharashtra State. Data collection was carried out with the help of a semi-structured interview schedule, from 90 respondents randomly selected from the village. Respondents were from three different groups belonging to fish marketing, casual labourers and homemakers in fishing households. In Versova fisher families, most of the family members are engaged solely in fisheries related activities and they were able to have a feel of the impact of climate change through various sources like mass media. Loss of shelter and declining income from fisheries complemented by unseasonal heat, decrease in rainfall, decline in fish catch and increase in price of fish for last 5 years were the most important impacts of climate change as perceived by them. All respondents reported lack of alternative livelihood opportunities. The findings of the study could help to develop appropriate strategies and policies to mitigate the impact of climate change to make fisheries more viable and sustainable for both fishers and fishing communities.
