Nomadism: An economic and social system based on pastoralism with a non-sedentary way of life. Nomads migrate with their herds taking their household and extended family with them. They follow the seasonal progression of rain vegetation. They live in tents and do not farm. Plant-based food is traded for products of livestock keeping. Semi-nomads farm and are sedentary with only part of the family migrating with their herds. Nomadism is an economic form which has adapted to the conditions of arid regions – often the only way to use the meagre production options without destroying them. Hence past attempts to make nomads sedentary have often failed or led to a clear deterioration of living conditions.
