Better Data, Better Results: Remote Sensing as a Tool for Monitoring Water Quality in Lake Toba, Indonesia

2019-06-01, World Bank

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.

Sustainability Assessment of Rural Water Service Delivery Models: Findings of a Multi-Country Review

2017-08, World Bank Group

With 2.1 billion people – mostly in rural areas – lacking safely managed drinking water and reported low rural water supply functionality rates, the Sustainable Development Goals pose a triple challenge: to reach unserved mostly rural population groups, to raise service levels, and to sustain existing and future services. This assessment uses a multi-country case study approach to identify good practices and challenges toward building sector capacity and strengthening sustainable service delivery models for rural areas. Recognizing the limitations of the Demand Responsive Approach, the emergence of various management models, the identified need for ongoing support to rural service providers, and the critical role of enabling institutions and policies beyond the community-level, the added value of this assessment lies in: i)the development of a comprehensive analytical framework that can be used to analyze and operationalize a more sustainable service delivery approach for rural water supply; ii) the rich set of cases and good practices from the 16 countries informing the global body of "knowledge in implementation," and iii) the formulation of recommendations and policy directions to improve the sustainability of services depending on sector development stage. Policy recommendations are centered around five areas: institutional capacity, financing, asset management, water resources management, and monitoring and regulatory oversight.

Toward Efficient and Sustainable River Basin Operational Services in Indonesia

2015-08, World Bank Group

Since the introduction of the Water Law in 2004, national river basin management in Indonesia has been carried out by 30 public river basin management organizations (RBOs), called either Balai Besar Wilayah Sungai(s) (BBWSs) or Balai Wilayah Sungai(s) (BWSs); the two are referenced together here as B(B)WSs. These national government agencies fill both regulatory and management functions, as well as undertaking construction, operation, and maintenance of river infrastructure and irrigation systems larger than 3,000 hectares. Provincial water agencies also provide water resource and river basin management in provincial basins and basins of national river territories, in coordination with the national river basin agencies.
