Clashes Over Grazing Land In Nigeria Threaten Nomadic Herding

Cattle owned by Fulani herdsmen graze in a field outside Kaduna, northwest Nigeria in February 2017.

Nomadic herders who live across West Africa are having to travel further and further south for their cows to graze. Some are letting cows graze on cropland, leading to deadly conflicts with farmers.
