What is EN ISO 27357:2011?

EN ISO 27357:2011 is an international standard developed by the International Organization for Standardization (ISO) that provides guidelines for determining the economic value of water-related activities. This technical article aims to explain the key aspects of this standard in an easy-to-understand manner.

The Importance of Water Valuation

Water is a fundamental resource that is vital for numerous human activities, including agriculture, industry, and domestic use. However, its value is often overlooked when making decisions about its allocation and usage. The implementation of water valuation methods, as outlined in EN ISO 27357:2011, helps to provide a more comprehensive understanding of the true cost and benefits associated with water-related activities.

Key Principles and Methods

EN ISO 27357:2011 introduces several key principles and methods for water valuation. One essential principle is the inclusion of both direct and indirect values of water. Direct values refer to the commercially measurable uses such as irrigation or hydropower generation, while indirect values encompass non-marketable benefits such as ecosystem services and cultural significance.

The standard also emphasizes the need for considering the entire life cycle of water-related activities. This means taking into account the upstream and downstream impacts, as well as potential long-term consequences on water resources and ecosystems. By adopting a holistic approach, the true value of different water uses can be properly evaluated.

Benefits and Applications

The application of EN ISO 27357:2011 brings numerous benefits across various sectors. For policymakers, it provides a decision-making tool to assess the most economically viable water allocation options. Industries and businesses can utilize this standard to evaluate the financial implications of their water use and identify opportunities for improvement.

Furthermore, the environmental sector gains valuable insights into the economic value of different ecosystems and can use this information to advocate for their conservation. Additionally, EN ISO 27357:2011 helps raise awareness among the general public about the true worth of water and encourages responsible water management practices at an individual level.

In conclusion, EN ISO 27357:2011 plays a crucial role in promoting sustainable water management by assigning a comprehensive economic value to water-related activities. By incorporating various principles and methodologies, this standard facilitates informed decision-making, fosters resource efficiency, and supports the preservation of essential ecosystems.
