Summary: This study provides an overview of the impact of climate change on rice production in Japan, and introduces a method to measure this impact by prefectures. The results show that temperature and precipitation have a negative effect on rice production for the entire country, while sunshine duration has a positive effect. The impact of these factors varies among regions depending on latitude and other factors. The study concludes that wind speed negatively affects rice production in most prefectures, while temperature has a positive effect except for the Kyushu region.

Summary: Higher levels of soil organic matter are associated with greater yields, lower yield losses, and lower rates of crop insurance payouts under drought in the United States. The positive effects of soil organic matter on yield resilience are partially explained by its impact on available water capacity and cation exchange capacity, with potential additional mechanisms not fully captured by those metrics. Overall, soil organic matter predicts yield resilience at regional scales and should be considered in agricultural policy and financial planning.

Summary: Atmospheric CO2 concentrations and water management practices both affect greenhouse gas emissions from rice paddies. This study found that elevated CO2 levels increased methane emissions under continuously flooded irrigation conditions, but had no effect under intermittently flooded conditions. Elevated CO2 had no effect on N2O emissions. Rice biomass and yield increased with elevated CO2, but were not affected by water management. These findings highlight the importance of considering changes in water management when estimating methane emissions from global rice agriculture.

Summary: Assessing the impact of climate change on agricultural production systems, this review provides a recent compilation of studies on irrigation needs and rice yields for a better understanding and use of climate and crop models. The discussion focuses on the strengths and weaknesses of climate impact studies, particularly on uncertainty and sensitivity analyses of crop models. It is found that the impacts of climate change vary across regions, seasons, varieties, and crop models.

Summary: Developing and disseminating resilient rice cultivars with increased productivity is crucial for addressing limited natural resources. A study in Egypt from 2000 to 2018 revealed annual reductions in both rice-cultivated area and production. Substituting certain cultivars has the potential to increase land productivity and save water, while climate variability negatively impacts rice productivity, with minimum temperature and precipitation having major long-term effects.

Summary: Rice, as a staple food for over 50% of the world's population, may need to increase production by more than 70% before 2050 to meet global food requirements, despite challenges posed by environmental degradation, climate change, and extreme weather events. This study predicts that rice production in Ecuador may be negatively affected under the Representative Concentration Pathway 8.5, but may have a smaller impact under pathway 2.6.

Summary: The implications of climate change on rice yield in China are significant, particularly due to the diverse cultivation practices and climate conditions across regions. This study investigated the regional discrepancies in the impact of climate change on rice yield using a model and future climate data. The findings suggest a projected decline in rice yield under different scenarios, with the most significant impacts in central, eastern, and northwestern China. However, low levels of climate change may benefit northeastern and southern regions. The study emphasizes the importance of considering regional differences in large-scale impact studies and provides valuable information for future policy decisions regarding food security in China.

Summary: The study explores Cambodian rice farmers' willingness to pay for weather-indexed insurance and finds that factors such as marital status, number of off-farm laborers, and farm size have a positive impact on farmers' willingness to pay, while the number of children in the household decreases the probability of demand for insurance.

Summary: This study demonstrates the potential for constraining the uncertainty of climate-related economic impacts through the use of impact emulators. By evaluating future climate change projections from 67 ESMs, the impacts in eight sectors were found to be closely related to recent trends in global mean temperature. The application of observational constraints reduced the upper bound of estimated economic impacts, thereby reducing uncertainty.

Summary: Climate change has led to an increase in frequent and severe torrential rains and floods globally, prompting the estimation of the associated costs as a priority for research. The 2018 Japan Floods particularly impacted vulnerable elderly individuals, resulting in the need for long-term care due to various health issues caused by the disaster. This study evaluated the effect of the floods on Long-Term Care Insurance (LTCI) costs and service utilization in Japan.

Summary: This study assessed the determinants of climate change perception and its impact on net farm income of rice farmers. Factors such as location, access to credit, educational level, and household size were found to significantly influence climate change perception. In addition, the study also indicated that smallholder rice farmers' net farm income is sensitive to marginal changes in both temperature and precipitation.

Summary: In this study, new schemes are proposed to reduce peak water volume during the beginning of the irrigation season, by dispersing the irrigation start dates based on the public goods game. The simulation results show that a scheme in which one farmer belongs to multiple groups and the groups overlap can increase the number of cooperating farmers and maximize the dispersion of irrigation start dates. Furthermore, a method is proposed to estimate the number of cooperators in each group through the dispersion of irrigation start dates.
