Karnataka state in south India is water stressed with increasing inter-sector water demands. The Krishna and Cauvery are the two major river basins flow through the State. However the water resources of the state are limited with approximately 1,072 m3 /person/year in eastward flowing rivers. The estimated water demand in the State is projected to rise by 40 per cent from 37,419 million m3 in 2000 to 52,366 million m3 in 2025. It is also estimated that due to competing demands, there will be a decline in the share of total demand for water from agriculture sector from 84 per cent in 2000 to 73 per cent by 2025. Meeting the anticipated rise in competing demands is a major challenge which if unmet, may constrain sustainable economic growth.
Water stress in the State is exacerbated by uneven spatial and temporal distribution of water resources and the predicted impacts of climate change. It has been documented that the poor coordination between various water users (like industry, domestic and power generation) contributing to sub-optimal management of limited water resources. Adopting an IWRM approach that promotes coordinated development and management of water, land and related resources will improve equitable economic and social welfare, while ensuring sustainability of the environment.
With the request of Government of Karnataka, the Asian Development Bank (ADB) approved the project preparatory technical assistance (TA) In December 2011 to support the Water Resources Department (WRD), State Government of Karnataka to formulate the Karnataka Integrated and Sustainable Water Resources Management Investment Program (KISWRMIP). The State has requested an ADB loan of $150 million and will provide $75 million counterpart financing with $ 5 million contributed by program beneficiaries. The total cost of the program is $230 million.
