District green - condition 2016

The ‘neighbourhood green’ geodata layer contains all clusters of publicly accessible green space with a minimum surface area of 10ha. This geodata layer was obtained by selecting all ‘green areas’ on the basis of the land use map (state 2016). These green areas were clustered algorithmically on the basis of contiguousness, also taking physical barriers into account. Subsequently, only those green areas adjacent to a public road accessible on foot were retained. Based on this, five grid layers (resolution 10x10m2) were created in which clusters were selected per function level based on a minimum surface area: neighbourhood greenery (>0,2ha); neighbourhood greenery (>10ha); district green (>30ha); urban green (>60ha); city forest (>200ha). The selected clusters with a higher function level are therefore always a subset of the selected clusters of a lower function level. Please note that, due to the method used, the green type ‘urban forest’ consists not only of forest, but of different types of green space. More information can be found in this background document: https://archive-general.environment.vlaanderen.be/xmlui/bitstream/handl… The method described therein was applied to the 2016 state land use map. The presence of greenery has a positive effect on a number of different aspects that determine a qualitative living environment. This includes a positive effect on physical, mental and social health, but also on biodiversity, climate resilience, landscape quality,... A common Flemish frame of reference (introduced in MIRA-S 2000) to assess the availability of green space states that every resident should have access to neighborhood greenery at a maximum of 400m, neighborhood greenery at a maximum of 800m, district greenery at a maximum of 1600m, city greenery at a maximum of 3200m and city forest at a maximum of 5000m. This data layer allows, among other things, to calculate the number of inhabitants in a certain area that has access to neighbourhood greenery taking into account the previously mentioned maximum distance.
