Since the projection of global warming emerged in 1980s with the potential of laying enormous impacts on agriculture and food security of the world, we have conducted experimental and modeling studies for clarifying its effects on rice production in Asia and for developing adaptive rice production technologies. On the basis of measurement of rice responses to climate and carbon dioxide concentration ([CO2]), the dynamic process model named SIMRIW was developed to predict global warming effects on irrigated rice. The model predicted differential regional effects of the projected global warming by doubling [CO2] on the rice yield over Asia, and indicated that high tolerance to heat-induced spikelet sterility and high yield potential under elevated [CO2] are the two important characteristics required for rice genotypes adaptive to global warming environment. Further, genetic traits associated with these characteristics and their genetic resources for breeding adaptive genotypes were identified from diverse rice germplasms. This article reviews our initiative studies in the light of the recent studies, and points out further research that is needed for better understanding and overcoming of this unprecedentedly large problem.

全球变暖和亚洲水稻生产：建模、影响预测和适应。

自 20 世纪 80 年代出现全球变暖预测可能对世界农业和粮食安全产生巨大影响以来，我们进行了实验和建模研究，以阐明其对亚洲水稻生产的影响并开发适应性水稻生产技术。在测量水稻对气候和二氧化碳浓度（[CO2]）的响应的基础上，开发了名为 SIMRIW 的动态过程模型来预测全球变暖对灌溉水稻的影响。该模型通过将 [CO2] 加倍来预测全球变暖对亚洲水稻产量的不同区域影响，并表明对热诱导的小穗不育的高耐受性和在 [CO2] 升高下的高产潜力是水稻所需的两个重要特性。适应全球变暖环境的水稻基因型. 此外，从不同的水稻种质中鉴定了与这些特征相关的遗传性状及其用于育种适应性基因型的遗传资源。本文根据最近的研究回顾了我们的倡议研究，并指出了为了更好地理解和克服这个前所未有的大问题需要进一步的研究。
