The Freshwater Health Index provides decision-support through a set of indicators that transparently assess the health of freshwater systems in their ecological and social dimensions. Built on the best available science, the indicators and measurement protocols quantify and map the multiple benefits that freshwater naturally provides.
The Freshwater Health Index focuses on three main components:
Ecosystem Vitality: The integrity and functioning of the ecosystem.
Ecosystem Services: The water-related benefits provided by a freshwater ecosystem.
Governance & Stakeholders: The structures and processes by which people make decisions related to water resources.
Each of these components is assessed with a suite of measurable indicators that are aggregated into an index. Evaluation of the indicators requires hydrologic and water allocation models, ecosystem service models, valuation techniques and stakeholder surveys.
