Under these programmes, district organizations provide additional labour and help to select benef iciaries. 70, Under this programme 6,951 units have been built, 4,164 of them (60 per cent) in Managua. Peasant settlements 71, After 1982, with the intensification of the war of aggression, it became necessary to meet the needs of peasant families affected by counter-revolutionary activities who were living in isolation and wanted to move closer to one another for self-defence purposes, 72, Three basic criteria determined the siting of these settlements: (a) Defence; locations were chosen to ensure greater security for the population living in combat zones; (b) Production: settlements were located in places where there was sufficient land to develop agriculture; (c) Services: settlements were provided with basic facilities and infrastructure. 73, The most common type of construction in these settlements is a basic 36 m^ module similar to the urban modules. In many settlements the first part of the building to be constructed was a roof in order to provide families with immediate shelter, and the walls and floors of dwellings were built later with community support. About 300 new settlements were built under this programme, comprising a total of 10,017 dwellings built in the face of great adversity: they were scattered and the projects were difficult to read, both because of the state of the roads and of the presence of enemy forces in the area, which accounted for the deaths of many builders, workers and specialists.E/1986/3/Add.l5 page 29 74. In order to carry out this building effort it was necessary to develop a system of enterprises capable of meeting the technical requirements for the 
analysis: The text describes a government program aimed at providing basic housing units to affected populations, including peasants and urban residents. The construction of these units is carried out in challenging environments, including war zones and areas with limited infrastructure. The program involves the provision of labor, technical, and administrative support, as well as the development of a system of enterprises to meet the technical requirements for the construction effort.
