Abstract
This paper presented a regional monitoring method for crop production in China and India in the recent era of water shortages in both countries. The research objective is to develop photosynthetic crop production index by utilizing world weather and satellite data to confront the crop production demands due to the population growth in China and India. Methods for monitoring cereal production have so far incorporated indices of accumulating atmospheric air temperature or vegetation Index NDVI in addition to precipitation data. However, the new era of water restriction caused by rapid population increase needs for photosynthetic model considering the effects of solar radiation and water stress effects in the regional crop production model. The proposed model aims to confront those social demands in Asia including Japan. Special emphasis was placed on rice production because of the demand for abundant irrigation in paddy fields.
