Blue-green infrastructure is essential to life quality. It provides places for recreation and relaxation, attractive views, connection to nature and a sense of place, and practical benefits, such as flood protection, shading and cooling, improved air and water quality, carbon storage and habitat for pollinators and other wildlife. Unfortunately, in Bucharest, the capital of Romania, the degradation of landscapes in the Metropolitan Area can lead to their abandonment or irreversible alteration. This study aims to develop an innovative method of creating a blue-green infrastructure plan as an essential part of the urban development plan. The IT component represents a methodologically innovative and original model in the European Union. Proposed land use in the studied area is valued in several categories (zero, low, moderate, high, very high). To evaluate the landscape characteristics of in the studied area, we used the values of biodiversity, socio-economy, connectivity, and type of ecosystem services offered. For a more accurate assessment of the landscape, CORINE 2018 and Urban Atlas data were used in conjunction with elevation. In order to define the connections between areas with high landscape characteristics (core areas), an IT solution was developed for evaluating the connections of different landscape elements with the ARCGIS - Linkage Mapper tool. By overlaying the obtained raster with the property raster from the National Agency for Cadastre and Real Estate Advertising and high-resolution satellite images, a realistic connectivity analysis was carried out in the studied area. The connectivity analysis was used to develop a blue-green infrastructure design scenariofor Bucharest metropolitan area.
