Modelling urban environments to promote ecosystem services and biodiversity: Case of Stockholm

Urbanization effects on vegetation and the alteration in land use is likely to be the major driver of fragmentation and the loss of ecosystem services (ESS) and biodiversity. Understanding varying levels of biodiversity within cities is pivotal to protect ESS. However, due to the high complexity of urban systems, ecological connectivity assessment in urban planning remains challenging. This article evaluates policy documents and tools for ESS assessment in Stockholm, Sweden. Stockholm is an interesting city for studying ESS planning and management since Sweden has a long tradition of formal policy for biodiversity management. An overview is presented of tools and approaches to measure ESS at different scale levels used in the urban planning process in Stockholm. Their application illustrates the complementary nature of these tools, but also the need to integrate them in a platform based on a GIS (Geographic Information System) model. Ultimately, the development of such an integrated tool should inform and support planning practice in guiding urban systems towards greater sustainability
