According to Eriyagama, Smakhtin & Gamage (2009) some mapping projects on
desertification have been carried out by some international organizations, but they
are not focused on droughts. Mapping has also been completed on various
characteristics that are often associated with droughts, for e.g. Mean Annual
Evapotranspiration, Global Humidity Index, Mean Annual Precipitation and
Temperature, Socio-economies, disaster vulnerability maps, etc., but the need to
map drought severity, in Pakistan, on district level, using a threshold value of
precipitation that could decide the degree of drought intensity, still remains. Thus
this research work focuses on this kind of focused mapping.
