The UN estimates as many as 2.2 billion people worldwide do not have access to clean, safe drinking water. As rising global temperatures, changing precipitation patterns, and a growing global population put additional pressures on this critical natural resource, water insecurity will likely become an even more important determining factor in global and regional conflict. In a recent paper in Food Security, researchers examine the role of water insecurity in two other related challenges: food insecurity and dietary diversity.

Conversations about climate change often focus on future effects, but according to the latest Assessment Report from the Intergovernmental Panel on Climate Change, changes to the global climate have already had a significant impact on food production. Global agricultural productivity has declined over the past 30 years by 1-5 percent per decade, and this deterioration is expected to continue, even if we only experience low levels of warming (+2 ºC).

Since it was first cited in a 1972 paper by the United Nations Economic Commission for Africa, the idea that women perform 60-80 percent of agricultural labor in Africa has been a central theme in the broader debate about gender and development. A new study released by the World Bank’s Living Standards Measurement Study – Integrated Surveys on Agriculture (LSMSISA) initiative is now calling this commonly accepted wisdom into question, however.
