Innovative solutions in the Lake Titicaca Basin, Bolivia and Peru (WWDR2, 2006)
Climate variability and associated changes in ambient temperatures are affecting the tropical glaciers of Peru and Bolivia. Between 1991 and 2003, the Zongo and Chacaltaya glaciers suffered both areal and volumetric losses. In fact, the Chacaltaya glacier, a small glacier at medium altitude, lost 97% of its mass between 1960 and 2003 and it is expected to disappear completely by 2010. Since glaciers are the main source of water for urban centres along the Andes and for irrigation systems both in the Altiplano and in the desert Pacific coast in Peru, the receding trend will translate into drought for thousands of people.
To meet the water and sanitation needs of the poor at an affordable price, in 2001, a water transfer project from the neighbouring basin of Misicuni was initiated. In April 2005, the first phase of the project was concluded, providing 500 l/sec to the city of Cochabamba, Bolivia. The project will be developed in three stages and is expected to provide 20,000 l/sec at the end of the third phase. A complimentary project also created a water consortium, which provides access to low-cost drinking water and sanitation in poor suburban areas.
