Water resources management in Chile
Much of Chile is dominated by the Andes Mountain range and many high altitude glaciers. With rising temperatures, the IPCC warns of increased melting for many of these glaciers, with some of them disappearing as early as 2020–2030. The Third Assessment Report from the IPCC indicate a critical situation for glaciers in neighboring countries such as Bolivia and Peru. The IPCC report goes on to say that glaciers in Chile are drastically reducing their volume at an increasing rate and that changes in temperature and humidity are the primary cause. In an article from Science Daily in March 2008, the news agency reports that, "if the inter-tropical glaciers of Chile, Argentina, and Colombia disappear, water availability and hydropower generation will be affected." Of the thirty test glaciers monitored in the Andes by the World Glacier Monitoring Service (WGMS) only Chile's Echaurren Norte glacier thickened between 2005 and 2006.
Hiking in Chile
Lying to the south of Coyhaique and on the route of the Carretera Austral, the Cerro Castillo National Reserve is named after Cerro Castillo, its highest mountain at 2,675 meters. The trail begins in the park’s Lago Monreal sector and runs 50 km to Villa Cerro Castillo. Points of interest include the Alero Las Manos de Cerro Castillo National Monument, a cave near Cerro Castillo where it is possible to view prehistoric hand print paintings dating back approximately 6,000 years. In November, rodeo tournaments also take place in the Villa Frei and Villa Cerro Castillo sectors of the park.
