MICRO-LEVEL DROUGHT VULNERABILITY ASSESSMENT USING STANDARDISED PRECIPITATION INDEX, STANDARDISED WATER-LEVEL INDEX, REMOTE SENSING AND GIS

摘要

The present day drought management practices adopt crisis management approach and not development programs for self sustainability. Drought vulnerability (Geographical, Meteorological, and Biophysical, Agriculture, Water resources and Demographic) assessment using exposure, sensitivity and adaptability is attempted in this study and demonstrated over a river basin, tributary of Krishna river system India. Satellite information and ground based observations and derivative indices such as Standardized Precipitation Index (SPI), Rainfall Anomaly Index (RAI), and Standardized Water Level Index (SWI) were used in the drought vulnerability assessment.
