Geographical stratification of urban green areas in European cities[The economics of density: evidence from the Berlin Wall]

This article studies the provision of urban green areas in cities where residents have preferences for the size of and access to those areas. At the optimum, the number of urban green spaces is a nonmonotone function of distance to the city center, while the sizes and distances to other urban green areas increase as one moves to the urban fringe. This article empirically investigates those properties for the 300 largest European cities by using the Global Monitoring Environment Services Urban Atlas database (European Environmental Agency). The empirical analysis confirms the nonmonotone relationship between the number of urban green spaces and the distance to the city center. The distance between two parks also increases as one moves toward the urban fringe.
