“…Long-term climate change will influence regional rice production in various ways (Watanabe and Kume 2009). According to the fourth report of the Intergovernmental Panel on Climate Change, the average temperature in Japan will increase by 4-6 degrees Celsius (°C) by the year 2100.…”

Rice productivity will be affected by climate conditions not only in own region but also in neighboring regions through technological spillover. Measuring such direct and indirect influence of future climate change is important for policy making. This study analyzes socioeconomic and climate factors in rice total factor productivity (TFP) and evaluates technological spillover effects by using the spatial econometric model. To consider geographical situation, we use hydrological model in addition to crop-yield and crop-quality models. Results show that spatial autoregressive tendencies were observed in rice TFP, even though the influences of climate factors were removed. Such spatial dependence brings about synergistic effects among neighboring prefectures in northern Japan and depression effects, like a spatial trap, from neighbors in southern Japan. Substantial impacts of climate change were as high as socio-economic factors but different in degrees by regions. Also, future climate change estimated by the global climate model enlarged fluctuation degree in rice TFP because accumulative or cancel out effects of temperature and precipitation occurred year by year. Therefore, technological development in rice production and provision of precise climate prediction to farmers are important in order to ease and mitigate these influences.Keywords Crop model Á Hydrological model Á Rice total factor productivity (TFP) Á Spatial lag model Á Research and development activities JEL code C21 Á Q54 Á R11 Á R15

“…Recently, high night temperature (HNT) stress has gained the atention in rice examine region. In the region of tropics and subtropics, critical ranges of an extremely narrow 2-3°C have caused severe reduction in grain yield [11,33]. Although the reduced yield caused by HNT may be atributed to higher respiration rates [23], the percentage yield decline was much higher than the percentage increase in respiration rate [11].…”

“…There is enough conirmation that, rising nightime temperature since in the middle of the twentieth century has been the major reason of enhances in worldwide mean temperatures and is thus the major aspect contributing to the yield decrease [11,12]. At the vegetative stage, rice with comparatively higher tolerance is tremendously susceptible during their reproductive stage against high temperature, mainly at lowering [13][14][15][16][17].…”

The mean temperature might rise up to range of 2.0-4.5 °C worldwide by the end of this century. Beside from this, a prediction has been made that rise in minimum night temperature will be at a quicker rate as compare to the maximum day temperature. Rising temperatures not only afect the crop growth process, but also lead to direct changes in other environmental factors and pose indirect efect on yield and quality of rice has been observed, so at the present stage, it aroused public atention. Breeds, including through breeding and biotechnology to improve high temperature tolerance of rice help to mitigate the negative efects of high temperature, however, progress in this area have been slow. By adopting diferent methods like sowing, water and nutrient management can also to some extent mitigate the efects of high temperature on rice performance, but in most cases, these techniques are inluenced by many factors, such as crop rotation, irrigation and other constraints like their applications are hard to applied to large area. Therefore, this chapter addresses (1) empirical reduction of rice yield (2) highlights the key signiicant mechanisms that inluence main grain quality atributes under high temperature stress (3) inducing stress resistance and adopting mitigation strategies for high performance of rice.

“…Climate change will impact rice production through increases in minimum and maximum temperatures, changes in the timing, duration, and intensity of rainfall events in basins where rice is cultivated, and the increasing concentration of CO 2 in the atmosphere [26][27][28]). While higher ambient concentrations of CO 2 can enhance crop yields, higher temperatures at critical stages of crop development can impair spikelet fertility and thus offset the potential increase in crop yields [29][30][31][32][33].…”

“…Higher CO 2 concentrations can exacerbate the sterility impacts of higher temperatures by reducing the number of pollen grains deposited on the stigma [34]. The net effects of changes in temperature and CO 2 concentrations likely will be negative in some locations and seasons, and positive in others, with variation across temperate and tropical climates [6,27].…”

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.
