The Urban Nature Indexes

The IUCN Urban Alliance, a broad coalition of IUCN constituents concerned with the urban dimensions of nature conservation, has unveiled a new knowledge product for measuring the ecological performance of cities: the IUCN Urban Nature Indexes (UNI). Comprising six themes with five indicator topics nested within each theme, the UNI is intended to help policymakers, stakeholders and local communities understand their impacts on nature, set science-based targets for improvement, and monitor progress using science-based measures. By enhancing environmental transparency and accountability, and by focusing on improvement rather than fixed targets, the UNI aims to catalyse local action for nature in all cities.
