However, sustaining the long-term economic andenvironmental value of Lake Toba depends on addressing thedeterioration of water quality. This technical guidance notereports on the potential benefits of using remote sensing aspart of an integrated strategy to improve the monitoring andmanagement of water quality in Lake Toba.
