Manasir tribe inhabits the desert regions close to the Nile valley. The exact size of this nomadic population is unknown, but it is estimated to be of the same order of magnitude as that of the resident farmers, i.e., tens of thousands. Both groups maintain tight cultural interchanges and trade relations with each other. Only the owners of real estate purportedly are covered under the compensation scheme, although reports are that families have been displaced without compensation or adequate provisions for relocation. Nomadic families will not receive any compensation, even though the resettlement of the farming Manasir will deprive them of their symbiotic partners. The consequences for their ability to sustain their lives in a harsh environment remains to be assessed. Human rights concerns UN Special Rapporteur on Adequate Housing Miloon Kothari issued a statement August 27,[2007], calling for a halt to dam construction at Merowe until an independent assessment of the dam's impacts on the more than 60,000 people who stand to be displaced by the dams at Merowe and Kajbar. Kothari stated he has "received reports that the Merowe reservoir’s water levels have already risen, destroying dozens of homes in the area and putting many more at risk." Kothari announced, "The affected people have claimed that they received no warning that water levels would be raised and that no assistance from Government authorities has been forthcoming since their houses were destroyed." According to reports, the Government of Sudan has not honored its promises to those who have been displaced. Kothari noted that, "thousands of people in the same area were relocated in similar circumstances that left many temporarily without food or shelter, and that some of those people remain homeless today." Kothari called upon the Sudanese government to ensure safety and adequate housing to all those affected by the dams and warned the projects "would lead to large-scale forced evictions and further violence." Archaeology The fertile Nile valley has been attracting human settlement for thousands of years. The section between the 4th and 5th cataract—a significant portion of which will be inundated by the reservoir lake—has been densely populated through nearly all periods of (pre)history, but very little archaeological work has ever been conducted in this particular region. Recent surveys have confirmed the richness and diversity of traceable remains, from the Stone Age to the Islamic period. Several foreign institutions have been recently or are currently involved in
