One of Africa’s starkest illustrations of climate change is found on the dried and desiccated shores of Lake Chad.
Within the last 60 years, drought and overuse have drained 90 percent of the lake’s water. Cameroon, Chad, Niger, and Nigeria all depend on it for irrigation and clean water. The effects of this ecological disaster in the Sahel region — forced migration and even political violence — are the social effects of climate change, an observation made by Médecins Sans Frontières (MSF) teams in the region. “The Sahel, long affected by conflict and insecurity, is now also increasingly affected by environmental factors that seriously impact the health and nutrition of its populations,” reads a 2018 policy brief written in partnership with The Lancet Countdown.
