Resumen
Descripción
Lake Toba is a unique natural asset of
global significance with a rich cultural heritage located in
the North Sumatra Province of Indonesia. Located 904 meters
above sea level and with a maximum depth of more than 500
meters, this 87-kilometer-long lake provides a wide range of
economic and environmental goods and services for more than
half a million people and 400 villages in the seven
districts covered by the lake's 3,658 square kilometer
catchment. However, sustaining the long-term economic and
environmental value of Lake Toba depends on addressing the
deterioration of water quality. This technical guidance note
reports on the potential benefits of using remote sensing as
part of an integrated strategy to improve the monitoring and
management of water quality in Lake Toba.
