Why were mobile animal herders not necessarily a threat to town life ?
1. Agriculture and animal rearing were carried out close to each other in this region. Some communities in the kingdom of Mari had both farmers and pastoralists, but most of its territory was used for pasturing sheep and goats.
2. Herders need to exchange young animals, cheese, leather and meat in return for grain, metal tools, etc., and the manure of a penned flock is also of great use to a farmer. Yet, at the same time, there may be conflict.

3. A shepherd may take his flock to water across a sown field, to the ruin of the crop. Herdsmen being mobile can raid agricultural villages and seize their stored goods. For their part, settled groups may deny pastoralists access to river and canal water along a certain set of paths.
