As “resilience” builds as a theme for the development community, a few key concepts are rising to the top of the conversation. [Video Below]

In 1941, glacial Lake Palcacocha in the Peruvian Andes burst its moraine dam of earth and stones, sending a torrent of water through the city of Huaraz and killing an estimated 5,000 people. Between 1941 and 1950, two more glacial lake outburst floods, or GLOFs, which can occur after enough water fills in behind a glacier’s end moraine, killed another 5,000 people in the Cordillera Blanca. In response, the government set up one of the most effective glaciological units in the world with the goal of preventing future outburst floods. Using drain pipes, reinforced terminal moraine dams, sophisticated tunnels, and valve systems, they drained or contained 34 lakes in the region. As a result, thousands of lives were saved.

When I began working in Liberia right after the Accra settlement ended Liberia’s civil war in 2003, I could not help worrying about whether the peace would last. Burnt-out cars lined the streets of Monrovia, bullet holes scarred many of its buildings and the wary U.N. peacekeepers manning checkpoints behind sandbags and barbed wire reinforced the sense that violence could flare up again at any time.

The Sahel – spreading from the Red Sea to the Atlantic as the Sahara Desert transitions to Sudanian savanna – is drought prone and suffers from chronic food insecurity. Yet, the region also boasts the highest fertility rates in the world, and the highest rates of marriage for young girls. This creates unique vulnerabilities that are being compounded by climate change, says ECSP’s Roger-Mark De Souza in an episode of Wilson Center NOW.

Stepping away from herds of cattle, subsistence farms, and other responsibilities at home, roughly a hundred Kenyan villagers traveled overnight by bus from the Tana River Delta to Nairobi in February 2011 for a hearing at the national high court. The claimants declared that the lack of a “comprehensive land use master plan” infringed on the rights of the region’s people, and called for the prohibition of further land and resource development until such a plan was negotiated.

From the mountains and foothills of the Himalayas to the Terai plains, climate change is rapidly changing life in Nepal. Many communities however, are not strangers to environmental stress; for decades, rapid population growth alongside agriculture and fuelwood collection have degraded land and diminished forests.
