Water has diverse use and in several areas, livelihood of the poor are intricately linked to availability of water. Recognizing the reality of multiple water use needs as the way forward needs to be reflected in our policies to move towards effective and sustainable management of water at all levels, from local to national level.
IWMI-TATA Water Policy Research Program is a collaborative initiative between a research institution and a corporate body, the International Water Management Institute (IWMI) and the Sir Ratan TATA Trust (SRTT). This partnership emerged from a shared concern regarding the growing water stress in different parts of India.
While the issues and problems related to water have been well articulated by several stakeholders over time, the IWMI-TATA program aims at evolving fresh perspectives and sustainable solutions by drawing from the vast research carried out across the country and take these in the form of policy recommendations to the policy makers at the national, state and local level.
Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including 
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities 
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But 
Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action.
