“Valuing Water” is a concept which has been mobilised to raise awareness on the intrinsic value of water, its instrumental value highlighting the essential roles which water plays in sustaining life and our societies, as well as relational value pertaining to managing the resource responsibly and ethically. The Valuing Water Principles offer a pathway towards sustainably, efficiently, and inclusively allocating and managing water resources, and to deliver and price water services accordingly. This Tool introduces the multiples values of water, challenges associated with valuing water, as well as how to incorporate these into decision-making within water governance.
The concept of Valuing Water was developed to recognise and celebrate the wide array of economic, social, and environmental values which water brings to our societies (HLPW, 2017). The concept of Valuing Water is therefore much broader than the traditional approach which focuses on finding the economic worth of the resource. For that, environmental economist developed the notion of Total Economic Value (TEV), which is commonly used to assign monetary merits to both use and non-use values (Figure 1). Those interested in methodologies for evaluating the economic value of water through shadow pricing techniques should refer to (Tool D1.02).

Valuing Water thus represents a paradigm shift suggesting that the process of valuing water should and cannot be only limited to deriving monetary values. This implies seeing water as an “social” rather than an “economic” good, one that has ecological, societal, and intrinsic value (VWI, 2020). As opposed to economic methods for calculating the monetary value of water, there are no specific methodologies to capture the intrinsic value of water (UNESCO, 2021, 25). Consider, also, that spiritual, emotional, and aesthetic values of water can be described and qualified but not “calculated”. In that sense, while the economic worth of water services can certainly be evaluated, its ecological but also socio-cultural and religious functions cannot easily be quantified.
