A technique for large scale drought monitoring (China National 94.8 Technique Import Project)

Drought is one of the main natural disasters that man has suffered since the ancient era. In China nation-wide droughts occur year after year, imposing severe threats to the food security and constraining the sustainable development of social economy.The Water Resources Information Centre of the Ministry of Water Resources of China (WRIC/MWR) developed an operational drought monitoring system in 1996, based on a river basin hydrological model. This system produces daily nation-wide maps of soil waterdeficit. However, it is felt that two aspects need to be improved: the spatial resolution is low (only 590 sites for whole China) and the hydrological model used in this system is a single-point model (interpolation between the points cannot reveal the actual situation). Alterra has developed the Surface Energy Balance System (SEBS) to estimate drought characteristic parameters using satellite remote sensing images. In order to import this advanced technique and apply it for the nation-wide drought monitoring, the Ministry of Water Resources of China funded a technique import project. This report shows the design, transplantation and modification of this technique to the Chinese situation, and the analysis of the first results of the new approach.
