United Nations World Water Development Report 2021: Valuing Water

The 2021 edition of the United Nations World Water Development Report–‘Valuing Water'–groups current methodologies and approaches to the valuation of water into five interrelated perspectives: valuing water sources, in situ water resources, and ecosystems; valuing water infrastructure for water storage, use, reuse, or supply augmentation; valuing water services, mainly drinking water, sanitation, and related human health aspects; valuing water as an input to production and socio-economic activity, such as food and agriculture, energy and industry, business and employment; and other sociocultural values of water, including recreational, cultural, and spiritual attributes.

These perspectives are complemented with experiences from different global regions; opportunities to reconcile multiple values of water through more integrated and holistic approaches to governance; approaches to financing; and methods to address knowledge, research, and capacity needs.
