ANALYSING URBAN GREEN SPACE ACCESSIBILITY AND QUALITY: A GIS-BASED MODEL AS SPATIAL DECISION SUPPORT FOR URBAN ECOSYSTEM SERVICES IN BRUSSELS
Stessens, P., Khan, A.Z., Huysmans, M., & Canters, F. (2017)
With the majority of people living in cities, urban green spaces are the primary source of contact with nature. Access to ecosystem services provided by urban green spaces is increasingly perceived as an important factor for quality of life, and it is a key component of sustainable urban design and planning. This paper presents a novel GIS-based tool to evaluate accessibility to – and quality of – urban green spaces. To demonstrate the tool’s applicability, it was implemented in Brussels. A series of indicators to evaluate the proximity to and quality of green spaces is proposed in the light of the analysis with the aim of supporting decision making and planning at the urban scale. The proximity and quality sub-models were parameterised through a comparative study of planning standards and through analysis of local preferences, acquired by means of a questionnaire. Applying the model to Brussels showed that approximately equally sized population groups have low, medium, and high access to green spaces. Concerning the proposed method for measuring green space quality, 62% of the population resides in urban blocks with access to green spaces with a lower than average quality score, which reveals a signif- icant margin for improvement.

USE-RELATED AND SOCIO-DEMOGRAPHIC VARIATIONS IN URBAN GREEN SPACE
Phillips, A., Khan, A.Z., Canters, F. (2021)
This paper explores use-related and socio-demographic variations in the valuation of urban green space (UGS) characteristics in the Brussels Capital Region (BCR), lending insights into the valuation of the cultural ecosystem services provided by UGS. Mismatches in the supply of and demand for UGS characteristics are also identified. Knowledge on the ways in which valuation of UGS characteristics vary and on an inadequate supply of UGS characteristics should guide and inspire planning and management of UGS to ensure that UGS provision meets the unique needs of communities. Online surveys were conducted in the BCR to determine how people use UGS, how they experience these spaces, and whether these spaces fulfil their needs for urban green Our findings indicate that socio-demographic characteristics (namely age and household composition) correspond with distinct patterns of use and valuation. Two subgroupings of users are identified: nature-oriented users and social users. Our accessibility analysis shows that, compared to social users, nature-oriented users tend to travel farther to reach their most frequently used UGS but are more often satisfied with the supply of UGS characteristics. Our findings point to an inadequate supply of nature and overcrowding of UGS in the city centre of Brussels. We recommend that planners not only consider size and distance in UGS standards but also consider the demand for UGS characteristics as well.
