6 aaaaaaaaaaaaaaaaaaa KRISHNA RIVER BASIN Krishna River Basin Krishna River Basin India s 4 th largest river basin. Area 258,948 km 2. 8% of total country area. River 1,400 km runs in 3 states. Maharashtra 305 km Karnataka 483km Andhra Pradesh 612 km Main tributaries, Ghataprabha, Malaprabha, Bhima, Tungabhadra and Musi. High degree of erosion in monsoon seasons.

7 Socio-economic Features : Very fertile black & red soil. Multiple variety of crops grown. Cultivable area MH. 10.4% of total cultivable area of country. Basin population million. 81% belongs to weaker sections of society. Dairy is a main activity. Small and marginal farmers involved in sheep and goat rearing. 16 Major projects are in basin.

8 Socio-economic Features : Culturable area in India P O P U L A T IO N S c h e d u l e c a s t e 1 4 % U p p e r c a s t e 1 9 % Kr i shna Basi n M. ha ( 10. 4%) B a c k w a r d c a s t e 6 7 % M. ha ( %) A. Weaker Sections -81% a. Schedule caste-14% b. Backward caste-67% B. Upper Caste-19%

9 Institutional Setup For Managing The River Basin Activities: SPVs For Funding & Execution: Krishna Bhagya Jala Nigam Ltd. Karnataka Neeravari Nigam Ltd. Command area Activities & Water Distribution: 6 CADAs are established in the state. Out of which 5 CADAs are in Krishna basin Water User s -Co-operative Societies Cater to 9.61 lakh hectares. Technical Support & Capacity Building: Karnataka Engineering Research Station. Water and Land Management Institute. Karnataka State Pollution Control Board.

10 Legal Provisions For Water Security: Article 262, 245, 246 & 248 of constitution of India. National Water Policy National Water Policy National River Linking Policy State Water Policy Karnataka Water Resources Authority 2008.

11 Budget Allocation And Expenditure For The Year Sl. No. Nigam Budget allocation for (in million dollars) (Rs. in Cr.) Expenditure during (in million dollars) (Rs. in Cr.) 1 KBJNL $ $ KNNL $ $

12 Issues & Challenges: Water allocation is by Tribunal. Eachstatehasitsownwaterpolicyandprioritizesofwateruse. 734 tmc allotment, for agriculture and 91 for drinking. Inadequate to cater 70 million people & to agriculture lakh hectare. Increasing demands on water resources for agriculture, domestic, industrial, and power sectors. Inadequacy in river water, over-exploitation of groundwater.

13 Challenges In Improving Water Security: River course: Flood forecasting& flood protection mechanisms. Rapid industrialization resulting excess demand for water. No expertise in water course management such as river protection works. River meandering, erosion and sedimentation in the river, etc. Catchment: Unplanned and rapid urbanization. Erratic & untimely rainfall, change in the rainfall pattern due to global warming. Reduction in the yield, need effective water management. Command area: Violation of cropping pattern, tail ender problems. Seepage and leakage in canal net work. Excessive irrigation by the farmers, water logging. Inadequate irrigation infrastructure dam, canal& distribution network.

14 Important Lessons Learned : Farmers Participation: Farmer s participation and decision making at the lowest level makes optimum usage of water. Designed cropping pattern enforceable only through PIM. Water management: Integration of surface water & ground water, a urgent need for optimum use of water. Inadequacy in skilled well trained and experienced Manpower in managing water. Inadequate Infrastructure: Irrigation infrastructures such as canal net work, head works, sluices / gates etc, areold&needsupgradationtomeetthecurrentdaydemand.

15 Knowledge Networking And Partnerships Envisaged key areas for exchanging information, knowledge and experience with river basin management professionals in Spain: River course management: Aquatic life management. River training works, banks erosion. Flood control, Flood Forecasting & Flood alarming. Catchment area management: Assessment of Precipitation for planning IWRM. Change in characteristic of catchment. Urbanisation & aforestation affecting yield of the basin. Command area management: Designing of Cropping pattern for optimum use of water. Canal distribution net work Instrumentation in canal regulation

16 Topics And Challenges For Partnerships With Water Organizations In Spain: Irrigation service reform & capacity building to meet the challenges. Integrated water resources management. Erosion in river basins and sedimentation in reservoirs. Aquatic ecosystems management in rivers and river basins. Surface water & Groundwater integration & management.

17 IWRM in Karnataka: Initiated by issuing a GO Dated Initiated CDTA through ADB for IWRM & sustainable water delivery. IWRM Covers: Drinking water & meeting the needs of various Industries. Efficient use of water for irrigation & bringing down wastage. Ensuring sufficient flow in the river for environmental security. IWRM Status: ADB Mission leader Vidisha.N.Samarasekara, visited Karnataka twice,for discussions on the IWRM proposal. Feasibility study for drinking water to 2 districts as a pilot project are in final stage. Extending the same to other urban and rural areas, in basin is under study. ADB consultants for CDTA are finalised & are on job by June 2010.

18 Proposed Questions For Discussions During The Visit. How Aquatic life in dry seasons in river course is being managed? What are the latest technology adopted in river training works and banks protection works? What are the latest and foolproof methods adopted in Flood Forecasting & alarming Flood control? How IWRM is managed in changed precipitation patterns, unseasonal & erratic rainfall? What are the laws enforcing to maintain characteristic of the catchment? What are the laws to control and monitor Urbanisation & aforestation affecting yield of the basin? How designed cropping pattern is being regulated in command area of the river basin?
