World Water Development Report 2021: valuing water

The 2021 edition of the United Nations World Water Development Report, titled “Valuing Water” assesses the current status of and challenges to the valuation of water across different sectors and perspectives, and identifies ways in which valuation can be promoted as a tool to help improve its management and achieve global sustainable development. Methodologies and approaches to the valuation of water are described through five interrelated perspectives: valuing water sources and the ecosystems upon which they depend; 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 are complemented with experiences from different global regions, opportunities to reconcile multiple values of water through integrated and holistic approaches to governance and financing mechanisms, and prospects to address knowledge, research and capacity needs.
