Kaduna's "tomato emergency" is part of a national dip in food production. In large parts of the northeast, production has been all but abandoned in the face of continued attacks by Boko Haram militants.

Even where food production remains strong, poor handling, storage and delivery methods mean that much of Nigeria's food is spoiled before reaching those in need. But now, in a bid to minimise post-harvest losses--which government estimates could be higher than 50% for some fruits and vegetables--businesses are beginning to develop new technologies to assist farmers.
