Thanks to sacrificial missionary service, churches exist. Noble labors gave birth to churches, Bible translations, clinics, rural development, and Bible schools. Mother-tongue Christianity now exist in Sahelian languages. Also, coastal Christians routinely migrate towards the Sahel for commercial, educational, or ministry purposes. Except for outreach to children, migrant churches chiefly serve their own people.
Droughts (since 1968) and jihadism (since the 1992-2002 Algerian civil war) have brought Christian and secular agencies to help those fleeing war and famine, including Sahelians illegally trying to enter Europe through Mali, Niger, and Sudan. Missionaries minister to refugees in major cities and secure NGO sites.
Christianity varies among Sahelian tribes. The strongest are the Mossi (31%), Gurma (19%), and Dogon (10%). Others have influential Christian minorities: Baatonu (5%), Bambara (4%), Hausa (2.6%) and Senoufo (2%). The least-impacted Sahelians are the Songhai, Tuareg, Zarma, Fulani, Mandinka, Tubu, Kanuri, and Sahara Arabs. Fortunately, there are effective mother-tongue ministries reaching them through radio, smartphones, hospitals, schools, and rural development. Social opposition to conversion is very strong, leading to shunning, shaming, expulsion, violence, imprisonment, kidnapping, and martyrdom.
