Water Security in Peru

Peru has 4.6% of the world´s freshwater , yet 2/3 of Peruvians live on the edge of water stress in the economically vital Pacific Basin

Water Insecurity in Peru

Water availability is declining in some areas, such as the Chancay-Lambayeque Basin in N. Peru that has seen a 63% decline in three decades.

In other areas, such as the Arma-Chichas watershed of Arequipa, farmers expect that the Coropuna glacier melt currently used to plant crops will disappear in the next 25 years.

Our regional insecurity is compounded by unequal water rights, wasteful use practices and poor infrastructure.

WASTE WATER RE-USE IN LIVESTOCK PRODUCTION

1. 2,000 HECTARES RECOVERED BY LANDLESS POPULATION.

2. IRRIGATION AND DRAINAGE IMPROVEMENTS, ALFALFA & FORRAGE PLANTED

3. YEAR ROUND USE OF CHICLAYO´S WASTE WATER FOR ALFALFA, FEED CORN AND SORGHUM CROPS.

4. TREATED WASTE WATER RESOURCES ARE ADMINISTERED BY THE COMMUNITY, VIA LOCAL MANAGERS.

5. THIS IS NOT AN ENGINEERING FEAT. SUCCESS IS DUE TO SOCIAL ORGANIZATION OF PRODUCTION AND CONFLICT RESOLUTION. CES SOLIDARIDAD PLAYED A KEY ROLE
