This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends developing small-scale irrigation and water-supply for humans and livestock and for water and soil conservation.
In the state of Pariaba, Brazil, Maria Dos Graces established the Agricultural Project for the cultivation of garlic by creating conditions whereby people could profitably stay on land which is very dry. She promoted simple irrigation for cultivation of garlic as a cash crop as well as the processing of garlic and creation of a producer's association. With the development of social infrastructures including education, health, food and water supply the migration of people from the village to the cities has stopped. The rural people have found for themselves a new sense of pride and satisfaction. In addition, imports of garlic into the state have been minimized.
