Ecosystem Services Valuation
A systematic approach to quantifying and assessing the economic, social, and environmental benefits that natural ecosystems provide to human societies.
Ecosystem Services Valuation
Ecosystem services valuation (ESV) represents a critical framework for understanding and measuring the various benefits that natural systems provide to human societies. This interdisciplinary approach combines elements of environmental economics, ecology, and social science to assign measurable values to ecosystem functions.

- Enhanced participatory approaches
- Better incorporation of ecological resilience
Impact and Implementation
ESV has become increasingly important in:
- Corporate environmental accounting
- National environmental policy
- International environmental agreements
- sustainable finance frameworks
The proper valuation of ecosystem services is fundamental to achieving sustainable development goals and maintaining ecological balance while supporting economic growth. As global environmental challenges intensify, the role of ESV in decision-making processes becomes increasingly critical.
