• 51 million tons in 1950-51 to more than 220 million tons at present.

• Country will need 450 million tons of food grains by 2050. This requires:-– more area under irrigated agriculture,– more agricultural productivity, and– improvement in irrigation efficiencies

Development of Projects

• Most of the earlier projects are standalone in nature, which needs to be brought under multipurpose role.

• Integrated approach has to be followed for all the reservoirs in a basin to efficiently use the available water resources.

• Demands are increasing compounded by increase in siltation in the reservoirs, thus making water availability further shrink in times to come.

• Apart from irrigation, industries are one of the large users of water. Inter-sectoral priorities have to be properly studied both from economics and social benefit point of view.

• The land use pattern and growing of water intensive commercial crops has put a lot of pressure on the water resources project.

Issues and Challenges

• Food Security : India would be requiring around 450 MT in 2050.

• Impact of Climate Change is apprehended to increase both spatial and temporal variability- leading to drought-flood-drought syndrome

Issues & Challenges

Water management has two facets.

• Supply side Conservation - efficient management of storage and diversion.

• Demand side Conservation – water use with minimal losses and consumption through prevention of wastage.

EFFICIENT MANAGEMENT

• Encourage participation of the Stakeholders in all relevant issues related to water development.

• Setting up of RBOs to address and take up water resources development.

• Reassessment by sophisticated technique to povide water resource availability

• Speedy completion of projects of National Importance

• To accomplish contemplated 20% increased water use efficiency by use modern techniques in irrigation.

• Address water quality issues

Way Forward

20

• Preparation and implementation of suitable catchment are treatment plans to reduce siltation in reservoirs.

• Proper maintainence of the existing projects by way of adequate funds and manpower.

• Setting up of RBOs to address and take up water resources development.

• Taking up research work in efficient management of water resources project.

Way Forward

I HOPE THAT IN THIS SESSION NOT ONLY THE

AUTHORS BUT THE PRESENT DELEGATES AND

AUDIENCE WOULD PUT FORTH THEIR VIEWS AND

SUGGESTIONS WHICH CAN EMERGE AS CONCRETE

RECOMMENDATION FOR BETTER MANAGEMENT OF

OUR WATER RESOURCES PROJECTS

Way Forward
