In 1994, the National Association of Irrigation Users (ANUR - Asociacion Nacional de Usuarios de Riego) was established to provide technical support to farmers, improve the management of irrigated agriculture and advise on the operation of irrigation systems and institutions. At present, 85 districts are in charge of managing, conserving and administrating water. They cover a surface of 3.5 million hectares and involve 477 users’ associations and over 500 000 farmers and producers.
