The damming of a river that feeds the world’s largest desert lake could lead not only to less drinking water for thousands of Kenyans, but international conflict between tribes for what little water remains.

To stop and perhaps one day reverse climate change requires changes big and small. Despite the thousands of power plants burning coal and other fossil fuels today, nearly 3 billion people still depend on solid fuels, such as wood, dung, and crop residues, for their daily energy needs.

In an effort to revamp the time-intensive process of conducting household surveys to collect health data in developing countries, a new project is using mobile phones and rapid processing techniques to generate regular updates for a tranche of indicators previously only adjusted every three to five years.

Climate change and conflict – what’s the relationship? In a recently completed set of field-based studies for USAID, the Foundation for Environmental Security and Sustainability set aside “yes-or-no” questions about whether climate change causes conflict and replaced them with pragmatic and politically informed questions about how climate change is consequential for conflict in specific fragile states.

From the Roman poet Juvenal’s observations about bread and circuses to Marie Antoinette’s proclamation, “let them eat cake!” the link between food and political stability is well established in pop culture. In academic and policy circles, however, it’s a source of considerable debate.

“Valuing women, paying greater attention to women’s rights – that’s the solution to our population growth issues and, I would argue, it’s also the solution to our food security challenges,” said Suzanne Petroni at the Thought for Food Summit in Berlin last year.
