A perfect storm of violence is breaking upon Africa’s Sahel. Since late 2018, communal conflicts—many over access to food, water or productive land—have produced thousands of deadly attacks. Across the region, nearly 4,800 people died in conflicts from November to March, according to the violence-monitoring group ACLED. The greatest surge in bloodshed is in Burkina Faso, where communal militias or religious extremists killed 500 people over five months. But amid the dire headlines, governments and civic groups in Burkina Faso and other Sahel countries cite progress in stabilizing communities with a basic step that simply has seldom been undertaken: broad, local dialogues among community groups, police forces and officials. Community leaders and government officials say they are now expanding those dialogues to improve national security policies to help counter the tide of violence.
