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.

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.

As recently discussed by the National Intelligence Council, sub-Saharan Africa is home to both the most rapidly growing populations in the world and its fastest expanding cities. Save the Children’s recent report, Voices From Urban Africa: The Impact of Urban Growth on Children, explores the challenges faced by the continent’s youngest age cohort, revealing what forces are driving children and families to migrate to urban areas and the poverty many are experiencing upon getting there. In response to the report’s findings, the authors recommend training and deploying more health care workers, facilitating public-private dialogue to identify long-term water and sanitation solutions, improving access to jobs and skills training, expanding access to early childhood care, and strengthening the education system to ensure widespread attendance. Compiled from 1,050 interviews, the report is unique for its first-hand accounts of the daily lives of children, their families, and community members.

“Over the past several months, extreme weather and climate events seemed to have become the norm rather than the exception,” writes Kelly Levin for the World Resources Institute (WRI). Indeed, records have been broken around the world as countries experience unprecedented heat, drought, flooding, or other types of severe weather. And people are starting to take notice. A number of recent stories try to make sense of this wild weather and what, if anything, it has to do with climate change.

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.

Set in the middle of the arid region between the Sahara desert and the equatorial savannas of Africa known as the Sahel, Niger is no stranger to drought. In recent years, however, droughts have hit more often, started earlier in the season, and lasted longer, creating a cycle of food insecurity that is becoming more difficult to break.

“Every crisis is complex, and the Sahel is no exception,” wrote USAID Assistant Administrator Nancy Lindborg in a recent Huffington Post article that called for “smarter programming and a coordivenated response” to chronic crises. “A regional drought has been overlaid with instability stemming from the coup in Mali and conflict in the northern part of that country where armed militant groups have forced the suspension of critical relief operations” and led to refugee movement into neighboring countries simultaneously challenged by drought and crop infestation. Understanding the complexity of this type of crisis, let alone visualizing the multiple factors that come into play, is a growing challenge for policymakers and analysts.

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.
