Grey infrastructure for housing, businessess, road infrastructure,... dominates in urban and peri-urban landscapes in Flanders.
In the context of an urbanised environment, green and blue infrastructure is to be understood as all natural and semi-natural landscape elements that (could) form a green-blue network. It can refer to landscape elements on various spatial scale levels: from individual rows of trees to complete valley systems. Examples of green landscape elements are hedgerows, copses, bushes, orchards, woodlands, natural grasslands and ecological parks. Blue landscape elements are linked to water. They can be pools, ponds and pond systems, wadis, artificial buffer basins or water courses. Together they form the green-blue infrastructure.
