Study finds irrigation more common on city farms than rural farms, intensifying water demands in sprawling urban zones
COLOMBO, SRI LANKA (13 November 2014) — Food production globally is taking on an increasingly urban flavor, according to a new study that finds 456 million hectares—an area about the size of the European Union—is under cultivation in and around the world’s cities, challenging the rural orientation of most agriculture research and development work.
“This is the first study to document the global scale of food production in and around urban settings and it is surprising to see how much the farm is definitely getting closer and closer to the table,” said Pay Drechsel, a scientist at the International Water Management Institute (IWMI) and co-author of the study, which was published in the November 2014 issue of the journal Environmental Research Letters.
The analysis, a collaboration between IWMI, under the CGIAR Research Program on Water Land and Ecosystems, the University of California-Berkeley, and Stanford University, is the first global assessment to quantify urban croplands and document the resources they consume, namely water, which has both environmental and food safety implications.













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.
