| Research Abstract |
The recent concern about food scarcity motivates the development of the present system entitled "Remote Sensing Environmental Monitor(RSEM)". The system is designed for treating carbon sequestration by vegetation, grain production, desertification of Eurasian grassland, and CDM afforestation/reforestation to a background of climate change and economic growth in rising Asian nations. The system includes a photosynthetic sterility crop yield model based on precise land use and cover(LULC) classification of crop field in two eastern Asian countries. This system also provides daily distributions of the PSN, which is the CO_2 fixation in Asian areas combined with the land-cover distribution classified from MODIS data, NDVI from SPOT VEGETATION, and meteorological re-analysis data by NCEP, U. S. A. The validation concept is based on the fact that the carbon hydrate in grains has the same chemical formula as cellulose in grain vegetation. The both photosynthesis and sterility models are calibrated by Carbon Partitioning Validation(CPV) method associated with particular rice species in Japan and China. However, more crop yield data are needed for validation of winter wheat and maize models. The mean CO_2 and carbon fixation rates in paddy areas were 25. 92(t CO_2/ha) and 5. 28(t C/ha) in Japan, respectively.
