The source above also says something about the afar, and them losing their pastural area. Forcing them to find new area to feed their livestock.
" No such thing as virgin land. Both UNFAO and World Bank officials told Econoff there is no completely unused land in Ethiopia. Almost all "unutilized" land that is not fenced off is used for livestock grazing, so the impact on livestock could be substantial. Ethiopia is dependent on livestock not only for milk, meat, and byproducts, but also for animal traction for plowing and transport. Livestock populations are already showing stress from being excluded from dry season pasture and water along the Awash river in the Afar region due to huge GoE farm irrigation schemes to grow sugar, cotton, and sesame. If livestock are negatively affected by becoming increasingly susceptible to drought and other environmental shocks, this would have a potentially huge impact on agricultural production in the dryer highland areas as well as loss of livelihoods in the pastoralist areas. Another challenge in this area is that many populations are semi-nomadic and shift their farming operations every couple of years. The GoE claims it is factoring these patterns into its land verification, but this traditional lifestyle could present investors with a compensation claim issue a few years down the road"
When the afars lost their land, they started fighting the Somali nomads for their land. The Ethiopian government is supporting the afars with military power, because they were the ones who caused the afar to lose their land.
