Irrigation

This deals with the guidelines of the Central Water Commission (CWC) for project appraisal of irrigation, flood control and multi-purpose projects for both major and medium projects, with inter-state ramifications revised in 2002. Under the new procedure the concerned State Government, in the initial stage first submits preliminary report covering surveys and investigations, international and inter-state aspects, hydrology, irrigation planning, brief environmental aspects, intended benefits etc., which are obligatory to establish the soundness of the project proposal.

This set of case studies is a part of a book prepared by Lokayan in collaboration with the Planning Commission titled “Seeds of Hope", covering themes of agriculture, biodiversity, education, forestry, governance, health, movements and water. The case studies related to agriculture and food security are summarised below:

This paper by the Challenge Programme for Water and Food (CPWF) presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat water productivity (WP) in Indo-Gangetic river basin, South Asia. It presents an innovative approach to combine meteorological data, ground survey, national census with remotely sensed imagery to assess water use, yield, and finally crop water productivity for the Indo-Gangetic rice-wheat cropping system in South Asia. 

The paper generated under the Challenge Program for Water and Food (CPWF) project explores in some depth a totally different dynamic in the irrigation economy of the vast Indo-Gangetic basin (IGB), an important exception to the global characterization. The global debate on ‘‘water as an economic good’’ presumes that irrigation water supply is delivered, controlled, and priced by public institutions. In the developing world, the price of water is kept so low that water use cost leaves farmers no incentive to use it efficiently. 

The paper by the Challenge Programme on Water and Food (CPWF) - Basin Focal Project provides a brief situation analysis related to water, agriculture & poverty, water resources, water productivity, institutional aspects and opportunities & risks related to the development of the Indo-Gangetic basin (IGB). Management of IGB water resources presents some formidable challenges and, therefore, steps must be taken towards integrated management of the IGB’s water and land resources in order to ensure the future sustainability of all production and ecosystems in the basin. 

This paper deals with basin water use accounting and is a contribution to the synthesis work of the CGIAR Challenge Program on Water and Food (CPWF) Basin Focal Projects. It applies principles of water use accounts, developed in the first of the series to the Ganges river basin in South Asia. It provides a means to assess the interactions between water, food, poverty, and the environment and helps develop sound information about water availability in a basin, where it goes and how it is used.
