Abstract
The paper focuses on block-wise assessment of crop water demand for irrigated agricultural areas in South-West Punjab with aim to develop a GIS based system for supporting infrastructural for water resources management. The average seasonal evapotranspiration (ET) demand of the region was estimated to be 725 mm for kharif and 537 mm for rabi season for 2007 to 2013. Blocks namely Lambi (890mm) and Bhagta Bhai Ka (701mm) had the maximum crop water demand whereas blocks Mahal Kalan (482mm) and Phul (323mm) had the least crop water demand. The ET maps derived in the study are useful in determining high water demand areas and can be helpful for planners to adjust the cropping pattern as per the micro level water availability in South-west Punjab.
