“…From a perspective of human-environmental system, vulnerability is more inclusive with natural, environmental, social, and economic aspects (Lee et al, 2013;Morss et al, 2011). The comprehensive vulnerability in a particular scenario is generally composed of exposure, sensitivity, and adaptive capacity (Krishnamurthy et al, 2011;Murthy et al, 2015;Wilhelmi and Morss, 2013). Yuan et al (2015b) interprets vulnerability as the imbalance among the three components, that is, the excesses of exposure and sensitivity as well as the shortfalls of adaptive capacity.…”

Risk management is an effective way to mitigate the adverse consequences of extreme events, and plays an important role in climate change adaptation. On the basis of the literature, this paper presents a conceptual framework for managing the risk of extreme events under climate change, and accordingly summarizes the recent developments with a focus on several key topics. In terms of risk determinants, the impacts of climate variability on the frequency of extreme events are addressed, and the various meanings and measurements of specific vulnerability are compared. As for the process of risk management, the dynamic assessment approach regarding future climate condition is emphasized. Besides, in view of decision making the available means to enhance the effectiveness of adaptation and mitigation strategies are highlighted. Finally, uncertainty is discussed with respect to its sources and solution

“…There have been efforts to include information on soils, irrigation, farm holding sizes, rainfall, rainy days, and cropping pattern combining them with satellite-based information (Murthy et al 2015) in assessing drought vulnerability in South Central Indian states Andhra Pradesh, Telangana and Karnataka. An integrated approach requires consideration of micro-level details on water demand and water availability along with the parameters above.…”

“…Current research on disaster exposure are focused on quantitative assessments of exposure, including statistics related to the spatial distributions of hazard-bearing bodies [8,9], estimations of hazard-factor intensities [10][11][12][13][14], etc. Wu used the crop choice decision model to calculate the sown areas of major crops based on the economic values, and the changes in crop habitat factors caused by climate change were not taken into consideration [15].…”

Due to the effects of global warming, extreme temperature events are posing a great threat to crop yields, especially to temperature-sensitive crops such as rice. In the context of disaster risk theory, exposure is central to disaster prevention and reduction. Thus, a comprehensive analysis of crop exposure is essential to better reduce disaster effects. By combining the maximum entropy model (MaxEnt) and a multiple-criteria decision analysis (MCDA), this paper analyzed the global distribution and change in rice exposure to high temperature. The results showed the future states of rice after exposure to high temperatures. Our results are: (1) the areas of potential rice distribution zones decreased within the representative concentration pathway (RCP) scenarios RCP2.6 to RCP8.5 in MaxEnt, where the long-term (2061–2080) decreases are greater than those seen in the medium term (2041–2060). (2) In the future, the number of high temperature hazards in potential rice distribution areas increased. In the RCP8.5 scenario, the intensities of global high temperature hazards on rice were reduced because the total area of potential rice distribution zones decreased. (3) Through the view of barycenter shift, the barycenter of the global potential rice and high temperature hazard distributions showed a trend of backward motion, which meant the global rice exposure to high temperature was in a downward trend. With the background of global change, this paper has great significance for the mitigation of high temperature risk in rice and its effect on the potential security of future global rice production. Future research is warranted to concentrate on discussing more socioeconomic factors and increasing rice exposure change from the temporal vision.
