Green urban areas as ecological indicators: combining in situ data and satellite products

Abstract

We investigated whether green urban areas (GUA) improve the urban environment. Field measurements were conducted to record noise and light pollution as well as other environmental characteristics in four GUA in Athens. The biodiversity status of the examined areas was derived from the existing data. Not all GUA represent ecological refuges, mostly depending on their configuration. Special attention should be drawn to planning and designing GUA so that human pressures could not penetrate. Soundscape assessment combined with artificial lighting, environmental and biodiversity status investigation of a site clarifies the edge effect of ecosystems leading to an alternative, integrated, multidimensional management approach.
