In Greek cities and towns, playgrounds, which represent a significant portion of open public space available in high density compact urban areas, fail to positively impact the sustainability of the urban environment, as they are made of artificial materials and generally lacking in natural elements. Designed around safety from accidents, a typical urban playground is equipped with prefabricated play structures, surrounded by an extensive area of rubber protective floor providing a surface safe from falls etc. This water-sealed surface does not absorb rainwater and has a very hazardous behaviour in hot temperature climates, such as Greece has. This “toxic turf,” a product of recycled elastic tires, contains chemicals suspect for cancer. In addition, trees and vegetation are usually insufficient or absent, thus worsening the overheating due to lack of shade. Although this model continues to prevail in Greece, around the world there is a significant shift towards natural playgrounds – play spaces that are designed to incorporate trees, shrubs, dirt, sand, grass, and play elements that are not industrially manufactured but constructed in situ, using stone, wood, reed, and other natural materials. From a pedagogical point of view, a stereotypical playground offers a rather dull and uninteresting environment for children to play, compared to the rich experience of a natural playground. Therefore, if designed as green infrastructure, playgrounds can considerably contribute to urban climate adaptation and a cooler microclimate and at the same time provide opportunities for urban children to come to contact with nature and benefit from free play. The scope of the paper is to present the multiple environmental benefits of natural playgrounds and to calculate the potential positive effects by the transformation of playgrounds into green spaces in a compact urban area. The field study examines the existing playgrounds in the municipality of Thessaloniki and their potential to become part of the city’s green infrastructure.
