Abstract:

The water resources sector is one of the key sectors facing several challenges in the context of burgeoning population and large scale unsustainable exploitation which will have its consequences for our future generations. More and more areas have to be brought under agriculture to provide the food security to the growing population. The unplanned interventions in the form of deforestation and conversion of forest areas into agricultural land and conversion of agriculture areas to urban centres have its own set of impacts. The adverse effects are visible with reduced water availability and many areas experiencing droughts on a regular basis. Drought scenario for Ajmer district has been analysed using drought indices namely rainfall departure, relative departure index and Standardised precipitation index. Statistical analysis based on coefficient of variance revealed high variability in seasonal rainfall. Most the area is under grip of drought with different severity class in 1985, 1991, 2000, 2002, and 2008. Based on RDI Mangaliawas is at highest priority for drought mitigation practises. Masuda and Mangaliawas are affected with regular occurrence of drought with drought frequency 1 in 2 years. The assessment using SPI revealed the spatio-temporal variability of different station. The present study attempts to assess the meteorological drought response to extreme climate condition. Long-term rainfall data (1985-2008) have been taken for evaluation.
