MODULE 2
Drought and its impacts
The purpose of this module is to familiarize participants with the key impacts of drought
in Bangladesh. At the end of this module, participants should be able to:
1. recognize different types of drought and their characteristics,
2. explain the factors contributing to drought, and
3. describe the impact of drought in Bangladesh.
The earth’s climate changes constantly with varying extremes of temperature, rainfall and air
movement occurring naturally. Droughts, periods of unusual dryness, are therefore a natural
climatic occurrence. They may be regarded as unusual in that they do not occur all the time
or occur only rarely in some areas, but droughts are not abnormal.
