Green spaces: a review proposes an ecological assessment framework, not a measure of health benefits

Criteria scattered across several disciplines

The researchers examined publications in ecology and environmental science indexed in the Web of Science and Scopus databases. Their starting point: the parameters used to assess green spaces are fragmented, with no unified classification framework.

The review distinguishes between urban and non-urban green spaces. These two contexts involve different spatial scales, management practices and ecological characteristics. This distinction matters when comparing assessments without treating all vegetated spaces as equivalent environments.

Seven categories to describe ecological quality

The proposed framework groups ecological assessment parameters into seven categories: vegetation condition, landscape integrity, hydrological regulation, human pressure, terrain-related factors, thermal and surface stress, and land-use and land-cover dynamics.

The aim is to structure assessments across different environments and scales. The authors present this framework as a tool to support the prioritization of conservation actions and resource allocation. However, the abstract reports no validation showing that it actually improves these decisions.

Well-being features in the review, but without clinical findings

Health and well-being are among the research themes identified, alongside ecosystem services and the thermal environment, among others. That does not make this publication a demonstration of the health effects of green spaces.

The abstract reports no intervention involving participants, no clinical comparison and no quantified effect on stress, attention or sleep. It therefore does not support recommending a particular type of green space or duration of exposure to obtain a personal benefit.

What we can take away

This review offers a proposed classification of ecological criteria. It helps clarify what is measured in a green space, but does not demonstrate how visiting it affects health.
