Ecosystem services mapping for green infrastructure planning-The case of Tehran

Cities are responsible for more than 70% of carbon-related energy emissions. In order to cope with the widespread effects of these emissions-in addition to improving technology and the use of green energy-it is necessary to reduce the volume of emissions with the help of green spaces at the point of origin. Green spaces provide extensive ecosystem services that improve the quality of life and urban ecosystem livability. Due to the expansion of urban areas, the volume of ecological resources has declined and these resources have become more disconnected. The ongoing reduction of these ecological resources makes their management and planning a critical necessity. We need to evaluate the multiple benefits of urban ecosystem services for appropriate ecosystem management and integrate those ecological benefits with the social characteristics of neighborhoods. This paper provides some analysis, as the first step, to assess the ecosystem services (ES) provided by the green spaces (supply analyses) and the social-ecological needs in these spaces (needs analyses). Next, these assessments are used to find the urban areas with the highest social-ecological needs and with the lowest supply of green spaces in order to provide a reliable basis for the multi-functional planning of green spaces. These assessments are also used to analyze the status of services provided in the environment and the services needed to respond to the people's cultural and ecological needs.
