Popis: Many territories tend to recognize the edge of open space as a strategic zone. The edges merge issues of urban development and demographic growth with the protection of natural spaces and the promotion of their value. The “lisière urbaine” (Urban fringe or Urban buffer) concept recognizes the edges as vibrant spaces with a variable thickness and where numerous projects could take place. The lisière urbaine concept is related to two main ideas. Firstly, this concept implies a connecting seam that stitches town and nature together and secondly, this zone is also viewed as a place for inward urban development. Numerous projects propose to build partially within an open space in order to define and structure a green space that people will use and respect instead of an undefined one that is threatened to be “eaten” slowly by buildings. But revealing previous urban voids raises major questions. Firstly, population growth around an open space requires adaptive measures for its management; do we know how we want to transform theses spaces? Secondly, the urban development of previously neglected zones raises the issue of the gentrification. And thirdly, where should the lisière urbaine be located, within the open space or within the built up area?In response to these questions, in the urban fringe, it seems imperative to focus with equal attention on the built form as well as on the non-built landscape. The lisière urbaine could be implemented by two complementary strategies: adapt and manage the open spaces on the edges of a natural or agricultural zone (the pomerio zone) and plan a permeable density in the built area around the open space (the ante parc zone).
