Drought is considered to be a normal feature of climate especially in tropical countries where occurrence of periods of dry weather during rainy season is common. Virtually droughts can occur in all climates and they can also be witnessed when the air temperatures are higher than the normal for a longer period that increases both evaporation and water deficit.

Approaches on drought monitoring, adopted by various countries, international cooperation in drought monitoring and drought monitoring mechanism in India are presented in chapter four. Decision Support Systems and applications of GIS for drought monitoring are also covered in this chapter. World food production and its variability, the impact of phenomenal drought during 2009 on food grain production in different countries, impacts of droughts on livestock, milk and fisheries production are covered under chapter five. Global surface waters, availability of surface waters in India, influence of drought on fauna and flora of surface waters and global warming on water resources at global and national level is discussed in chapter - six.
