Mapping and Assessment of Urban Ecosystem Services: Capacity in Vilnius City

Abstract

Ecosystem services (ES) are the benefits people gain from ecosystems, which are essential to human well-being. ES concept allows us to demonstrate more clearly the importance of nature, understand its benefits and justify its preservation. Knowledge on ecosystem’s capacity to provide services and the demand for these services allows us more effectively organize spatial planning, avoid conflicts and protect the ecosystems from degradation. This article reviews one of the ES assessment and mapping method called ES matrix model and presents its application to Vilnius case study. Using the method and expert knowledge twelve ES were assessed and mapped. The review of the method has shown that it can be applied at different scales and to evaluate several ES simultaneously. In previous studies, the method was applied to assess ES capacities both locally and at European level, often using expert knowledge for ES evaluation. Method application for the case study confirms that the results of the evaluation mainly depends on primary data, i.e. the scale and accuracy of the land used map and the sufficient sample of experts. The case study showed that the lowest concentration of evaluated services is in the center of Vilnius town and surrounding neighborhoods, and as the distance from the city center increases, the number of ES increases as well. An ES richness map, which shows how many different services exist in a given area, showed a low number of ES in the central and western part of the city (a maximum 6 out of 12 services rated). Additional research, however, is needed to assess the quality of the existing services. Such an assessment of the ES potential and the quality of the services can serve as an additional tool for territorial planning and efficient use of green urban spaces.
