There are conflicts between nomads and settled village dwellers, as nomads are forced to move their herds north after the first rains of the season but often have no pastures ready in the north. There are steps being taken to combat desertification in the Sahel, most notably by the Eden Foundation, but also by other groups.
The authorized travel days are calculated using 350 miles/day (based on the DTOD distance between the authorized points) for an employee or member. 1 travel day is allowed for each 350 miles of official distance of ordered travel.
How is it figured? The military computes your per diem payment based on three factors-the number of travel days, the current CONUS standard per diem rate, and the ages of the travelers. The number of travel days is based on a standard 350 miles per day if you are traveling by Personally Owned Vehicle (POV). To determine the number of days per diem, take the Official Government Mileage between duty stations and divide by 350. An additional day of travel is allowed if the remainder is 51 miles or more. The per diem rate is based on the current CONUS Standard Per Diem rate and varies by age.
