Volunteers are seen laying a piece of the irrigation canal. - - Rural Works Programme (WFP). Since 1966 the UN/FAO World Food Programme has committed food worth more than $21 million to assist the National Rural Works Programme. The aim is to encourage volunteers to carry out works useful to the community and to increase agricultural production. By the end of the project in 1974 more than 18 million man days of work will have been given by volunteers who receive a family ration for each day worked. A typical example is the village of San Antonio Tlatenco in the state of Puebla, where villagers have almost completed an irrigation canal which will bring them abundant water from the volcano Istaccihuatl. The community raised funds for the 12 kilometre pipeline and 400 volunteers made 13,500 cement pipes by hand and laid them. Among the numerous economic benefits which villagers will derive from the water will be a canal system to fields which will enable farmers to raise two major crops a year.
