ughts make it impossible for the Nuer to live in one place year-round. During the rainy season, the floods come and make the Nuer retreat from the low-lying areas to their rainy season villages on higher ground. At this time they must cultivate crops in order to supplement their meat and milk products, foodstuffs provided by their cattle, which is usually millet that grows fairly well inland away from the flood plains. After the floods and rains pass, drought sets in quickly, bringing the Nuer down from higher ground to search for water and grass lands to graze their cattle and to find fish in the pools of water and small lakes caused by the flooding. The Basseri live in southern Iran, hundreds of miles from the Nuer, and are a nomadic society whose migration route is nearly three hundred miles long and almost fifty miles wide. The Basseri territory ranges from the mountains to the desert, throughout this range there is little rain. Precipitation in the mountains fall as snow, thus there is more vegetation and forested land in this area. In the flat and low-lying areas, the summer is defined by drought with a little bit of grass showing up during the winter rains. In order to keep their flocks healthy, the Basseri travel over lands owned by agriculturists whom use irrigation to supply their crops with water and after harvest welcome the nomadic people to graze their flocks, because the manure acts as an excellent fertilizer....
