Water Availability, Risk and Resilience incorporates hydrological and hydrogeological assessments at river basin, aquifer, country, regional and global scales under current and future climate scenarios, provides services to other themes for modeling of water resources scenarios, and enhances availability and delivery of water resources data through the use of earth observing system satellites and information and communications technology (ICT).
It is the home of IWMI’s work on water-related disasters, such as floods and droughts, climate variability and change, and various adaptation options, including improved planning and operation of alternative forms of surface and subsurface water storage.
It enhances the understanding and supports evidence-based management of climate and water resources variability, taking into account environmental and social objectives in order to reduce risk and vulnerability, and increase the resilience of rural and urban populations.

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.
