New evidence on the effects of integrating farmers with the global food chain
Smallholder agriculture – the safety net of many rural people in developing countries – faces a future of increasing volatility and risk. This is the result of more farmers becoming part of the global economy and of their exposure to climate change impacts.

More collective action in rural communities would seem to be the logical response. But according to a study published recently in the Proceedings of the National Academy of Sciences of the USA, just the opposite is likely to happen when collective risks increase: Community members show an inclination to invest less in shared infrastructure, such as irrigation systems.
This was the conclusion of research to which the International Water Management Institute (IWMI) contributed. The study authors gauged participants’ response to risks threatening their private versus collecting earnings, using a public goods game in 118 small-scale rice farming communities of China, Colombia, Nepal and Thailand.
Across countries, risk to collective earnings prompted the lowest investment in public goods. The only country in which a preference for communal investment declined significantly in response to increased risk for private earnings was Nepal, where outmigration is rampant and remittances account for 30 percent of gross domestic product. This suggests that if the flow of remittances from Nepali migrants is jeopardized, individual community members will have less money to invest in public goods.
Small-scale farmers connected with the global economy will gradually gain access to productivity-increasing technologies that reduce the need for cooperation. In the meantime, though, investing in shared resources remains necessary for increasing productivity and strengthening food security, especially in rural communities that face labor shortages resulting from outmigration.

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.
