KANO: Weeks into Nigeria’s crucial annual rainy season, farmers across the north are abandoning their lands due to attacks by armed groups, threatening the food supply of Africa’s most populous country. Jihadists and “bandit” gangs specializing in kidnapping for ransom and cattle rustling terrorize communities in northern and central Nigeria, where they launch deadly raids and impose levies on farmers wishing to access their own fields. Some farmers, after paying ransoms, have no money left to pay the “taxes” to access their land.
