Since the arrival of mechanized farming, the durra stalks which appear to be a nutritionally adequate type of fodder, have ensured a certain degree of security for the pastoral system. In Sudan, camels are the only domestic animals that can exploit this precarious ecological niche due to their ability to work in extreme temperatures, which can be artificially created by mechanized agriculture. Drinking spots are scarce in the area, and sheep and goats would be unable to move far enough from the few available water sources to utilize the vast expanses of harvested fields. Camels require watering approximately every six days, for which they are usually driven to the Atbara River. Camels are also able to migrate far enough north during the rainy season to utilize the only remaining non-cultivated areas.
