This publication summarizes the strengths, challenges, opportunities, and risks characterizing the prospects for integrated water resources management in Indonesia. Integrated water resources management planning is essential for sustainable growth. Indonesia’s rapid economic growth, increasing populations, and trends in developing and urbanizing environments are leading to potential conflicts as more users claim the same water resources. Understanding these conditions may provide decision makers with more insight to optimize the country’s water resources potential using available and state-of-the-art methodologies and tools for river basin planning. The report discusses all aspects of basin planning based on experiences from one of Indonesia’s most complex and strategic river basins.
