Abstract

 

Cholistan is a region highly vulnerable to meteorological and hydrological droughts, primarily because of the occurrence of extremely low and variable intra and inter-annual precipitation and high rate of evaporation. As a result plant, animal and human life is often disturbed badly. Thus, proper investigation of drought occurrence patterns and associated problems is a basic need for the effective future development planning of the region.  The study in hand aims to appraise the spatio-temporal occurrence of meteorological droughts and associated problems in Cholistan region of Pakistan. To assess drought severity, the Standardized Precipitation Index (SPI) has been computed using meteorological data of 33 years (from 1981 to 2013) for ten sample areas having unique geographic setup. Time series data of precipitation was obtained from the Pakistan Meteorological Department. Observations about water availability and vegetation conditions etc. were recorded during field visits also. It was found that during major part of the year, the region remains extremely arid and meteorological droughts occur frequently. Repeated threats of droughts make the floral, faunal and human life extremely hard in Cholistan. As a result, ecosystem of the area along with human and animal life is badly affected. Nomadic life is seriously disturbed and nomads are forced to migrate towards relatively safe places to save their animal wealth. If water is made available, impacts of meteorological droughts can be lessened and this desert region of high plant and animal production potential can be converted in to a fertile and productive area. The findings of the study may provide help in preparing an effective strategic plan for overcoming the vulnerability of disaster prone areas and to reduce the damages caused by meteorological droughts.
