Green Fences for Buenos Aires: Implementing Green Infrastructure for (More than) Air Quality

Schoolyards in North America and Europe are increasingly using green fences as one measure to protect vulnerable populations from localised air pollution. This paper assesses the possibilities limits for mobilising this format of site-specific infrastructure cities low- middle-income countries beset by pollution multiple other socio-environmental challenges, particularly questions definition a quality (GI4AQ). We applied several qualitative action research methods question fence implementation Buenos Aires, Argentina—a Latin American city with weak air-quality policies, limited infrastructure, little experience nature-based solutions. Firstly, we conducted literature review role that urban vegetation ecosystem services may play AQ policy barriers such approaches globally city. Secondly, planned, designed, constructed, maintained, evaluated pilot school playground. Thirdly, carried out supplementary interviews stakeholders expert informants compiled project members’ narratives respectively characterise encountered delineate its attributes based on associated actions took overcome complete pilot. Our findings identify across seven known categories (institutional, engagement, political, socio-cultural, built environment natural landscape, knowledge base financial) highlight examples not previously considered extant international literature. Furthermore, learning experience, proposes an expanded model plus multi-dimensional co-benefits (GI4AQ+) increase chances attending local needs priorities.
