How is the land use-cover changing in drinking water catchments in the coastal range of south-central Chile (35° - 38.5° S)?

Different studies on land use-cover change (LUCC) have revealed substantial loss of native forests in south-central Chile in the last decades. However, little information exists about LUCC in drinking water catchments (DWC) affected by water scarcity. We analyzed the LUCC in 25 catchments that suppl...
