Integrated and Sustainable Water Management:Science and Technology

Water is a key factor in sustainable development of a nation. Hence, the status of water resources and their sustainability, particularly in the arid and semi-arid areas of the country, are of prime concern. Rainfall, the source of all water on earth, has a huge spatial and temporal variation in the Indian subcontinent; it is mainly confined to four months during the monsoon season in a year. India has nearly 33% of its geographical area in the semi-arid and arid category. A substantial part of the arid and semi-arid areas is drought-prone.
