Paper Abstract

Drought occurs everywhere in the world and is one of the costliest natural hazards. The Group on Earth Observations (GEO) has advocated implementing a Global Drought Early Warning System (GDEWS) since 2007. Various indices have been developed and used to depict drought. According to the survey, various drought monitoring system with remote sensing at regional, national or local level are existing, but the integration with the drought system based on the weather station data, in particular at the global level is still weak. However, the GEO Global Agricultural Monitoring Initiative was recognized by the G20 agricultural ministers and will enhance the linkage between GEO-GLAM and GDEWS. The capability for a component of drought monitoring with remote sensing is there in place. MODIS data have been used to globally track the distribution of crop failures due to droughts. In China, the Chinese meteorological satellite, FY is also ready to monitoring drought globally. MERSI onboard FY-3 is similar with MODIS and helpful to monitor the occurrence, development of drought at different scales. JRC MARS issues periodical bulletin on agricultural conditions. Agricultural Division of Statistics, Canada issues weekly crop condition reports. In India, the biweekly drought bulletin and monthly reports is issued under National Agricultural Drought Assessment and Monitoring System (NADAMS). Similar program is followed in many countries world-wide. The informed information of drought is helpful for governmental officials and formers to in advance prepare for coping with the likely coming drought. The global efforts should be in place to promote the global drought information system with a remote sensing drought component.
