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.

Once considered a model for Sahelian democracy, Mali’s liberal regime (assessed as “free” in Freedom House’s annual survey of democratic governance continuously from 2000 to 2011) virtually disintegrated in March 2012 when a group of junior army officers, frustrated by the central government’s half-hearted response to a rebellion in the state’s vast northern tier, found themselves – somewhat accidently – in control of the state.

Stretching across northern Africa, the Sahel is a semi-arid region of more than a million square miles covering parts of nine countries. It is home to one of the world’s most punishing climates; vast expanses of uncharted and unmonitored desert; busy migration corridors that host human, drug, and arms trafficking; governments that are often ineffective and corrupt; and crushing poverty. It is not surprising then that the area has experienced a long history of unrest, marked by frequent military clashes, overthrown governments, and insurgency.

“There is a huge gap between climate science, policymakers, and the end-users, in terms of understanding climate change and adaptation, and how that relates to conflict or peace,” concluded 26 experts from more than 10 countries across sub-Saharan Africa at the Wilson Center last fall. But “climate change adaptation is crucial to achieving Africa’s aspirations for peace, security, and sustainable development.”

Much ink has been spilled on the growing trend of global land grabs – land purchased en masse in developing countries like Ethiopia by foreigners mainly for agricultural export. But along with land, investors often also gain the right to use local water, and sometimes with little consideration for local livelihoods. Fred Pearce recently looked into these “water grabs” in a series for National Geographic.

For many people, Timbuktu has long represented the essence of remoteness: a mythical, faraway place located on the boundaries of our collective consciousness. But like many of the myths associated with colonialism, the reality is very different.

Over the past few months, the Sahel drought has sparked attention of news media and concerned citizens around the world. Throughout this media blitz, I have been struck by the sharp contrast between this coverage and how the devastating effects of malnutrition are usually portrayed. Malnutrition is often overlooked in favor of more “newsworthy” diseases, and it takes a crisis to focus our attention on this public health issue. Yet an emergency such as this drought – affecting more than 18 million people, including nearly 2 million children – is difficult to ignore.

It is the lean season in the Sahel, a spine of arid and dry lands that runs from Senegal to Chad in western Africa, and once again we are seeing the devastating images of children gaunt with hunger. This is a region that faces high childhood malnutrition and underdevelopment even under the best of circumstances so one poor harvest can push millions of the most vulnerable into severe risk. In the aftermath of poor rains, and with food prices stubbornly stuck on high since the food crisis of 2008, some 18.7 million people across eight affected countries in the Sahel are at risk of food insecurity this year alone. At least eight million people are already in need of emergency assistance.
