On May 11, Pakistan’s Election Day, approximately 60 percent of eligible voters went to the polls. This figure far exceeded the 44 percent who turned out for Pakistan’s previous election in 2008. Media reports have featured moving accounts of the elderly being carried to the polls, and of women standing in the heat for hours to cast their ballots.

The 2011-12 West African food crisis led to riots in Senegal and Burkina Faso as well as food insecurity for millions of rural and urban poor across the region. The crisis emerged from a number of factors, including instability in northern Mali, increases in global food prices, and low rainfall in the 2010-2011 and 2011-2012 growing seasons. Many countries in the region are now reassessing and expanding domestic agricultural capabilities. At the top of the agenda for Senegal, a democratic republic on track to reach many Millennium Development Goals, is reducing youth unemployment and increasing domestic agricultural capacity.

A staggering amount of development dollars – one in three, in fact – are lost due to natural disasters and crises. Certain communities are less affected than others by such disasters; they are more resilient. Knowing where vulnerability and strength exist and how to bolster them could help avoid these losses. Yet, today, very little data exists to help development practitioners understand which adaptive capacities are lagging in a given community.

Several high-profile reports in the last few months have suggested that climate change and natural resource scarcity contributed to the events that have rocked the Middle East and North Africa (MENA) since December 2010. Thomas Friedman is apparently working on a Showtime documentary about the topic. But what exactly was the role of environmental factors in the mass movement?

Natural disasters have dominated news coverage in the past several years, with many observers noting a distressing rise in the frequency and scale of disasters as well as rising costs. Despite these worrying trends, a critical mass of leadership and public support for doing something about it is emerging.

Water is the foundation of human society and will become even more critical as population growth, development, and climate change put pressure on already-shrinking water resources in the years ahead. But will this scarcity fuel conflict between countries with shared waters, as some have predicted, or will it create more impetus for cooperation?
