Drought is considered by many researchers to be the most complex but least understood of
all natural hazards, affecting more people than any other hazard. Drought affects many
aspects of community and environment, and any future increases in the water demand will
be most critical in periods of severe drought. Geospatial analysis of the historical drought
events and their causes can be used to mitigate drought impacts and to develop
preparedness plans. This study aimed to identify the changes in drought frequency …

Drought is one of the natural disasters which annually claim the most victims. Drought affects
many aspects of environment and society, and any future increases in the demand for water
will be most critical in periods of severe drought. Geospatial analysis of the past drought
events and their causes can be used to mitigate of the drought impacts and development of
preparedness plans. The main objective of this study is to investigate the changes in drought
frequency, persistence and severity in the Eastern Nile basin during the period 1965-2000 …
