Assistance and Reintegration (ANAIR). This institution worked in collaboration with the Office of the UN High Commissioner for Refugees (UNHCR) and other Un agencies for the implementation of a broad programme on the reintegration of returnees. In this regard, a tripartite agreement was signed in 2007 between Mauritania, Senegal and UNHCR. Actions in favour of families and women returnees were conducted focusing on the distribution of thousands of dairy cows, the opening of community shops, establishment of cooperatives for market gardening, poultry farming and child care, and literacy centres. Children who returned during the repatriation operations were able to attend primary school at the refugee camps. Those in secondary education were enrolled at nearby schools. The civil registration of returnees was a major concern for public authorities who ultimately registered all returnees and issued them with civil registration papers. An institutional mechanism for the reintegration of public servants victim of the 1989 events was established and has since conducted an exhaustive survey of these public servants and ensured the reintegration of teaching and national education support staff as well as. The children’s parliament organized a special session on the theme: “Consolidating national unity” in which repatriated children also participated. A summer camp was also organized for dozens of repatriated children who spent two memorable weeks socializing with young children in the same region. Other repatriated children also participated along with children from all regions of the country in a summer camp organized in Morocco.
