Alejandra Kurbán

Abstract
Within the sustainability of cities located in arid environments, bioclimatic indicators of urban green are proposed, taking as a study case the Metropolitan Area of San Juan, Argentina, city located in the arid strip of South America, which has one of the most rigorous climates of South American arid areas. The state of situation of European and Latin American cities is analyzed, and results of investigations performed in the aforementioned city are considered. It is suggested to adopt as bioclimatic indicators of urban green, two parameters that represent equivalent values: one, which relates the area of green spaces in the city with its population; and the other, which relates it to the area of urban land. The first, called Bioclimatic Indicator of Urban Green Areas Density, results 9%; the second, designated as Bioclimatic Indicator of area of urban green spaces per inhabitant, obtained a value of 25m2/in hab.
