During the 2018 High-Level Political Forum on Sustainable Development at the United Nations Headquarters in New York, this July, IFPRI organised a side event called “Investing for Reshaping Food Systems”.
Speakers included Claudia Sadoff, director general for the International Water Management Institute; Nichola Dyer, from the Global Agriculture and Food Security Programme at the World Bank; Gerda Verburg, coordinator at the Scaling Up Nutrition Movement (SUN); and Chantal-Line Carpentier, chief at the U.N. Conference on Trade and Development.
They all emphasised the urgency of investing in sustainable agriculture, defined by the Barilla Centre for Food and Nutrition as “the efficient production of safe, healthy, and high-quality agricultural products, in a way that is environmentally, economically, and socially sustainable.”
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.
