Promotes the efficient use of water resources at the plot level through public and public-private investment in technified irrigation systems, extending its scope to rainfed areas, irrigated lands, grazing lands and arid lands with agricultural potential. It assigns shared responsibilities across the three levels of government, water user organizations, and peasant and native communities, making adoption mandatory in non-regulated irrigation zones and recommended in regulated ones. Financing relies on incentives drawn from public resources, donations, debt operations and international cooperation, and the law repeals the Technified Irrigation Program created by Law No. 28585.
