“…In addition, since the implementation of Natura 2000 implies that activities in and around protected areas can have significant effects on protected natural values and need to be assessed (Beuen, 2006), it can be seen as a tool to promote land-use planning that integrates nature conservation requirements. Spatial planning, therefore, finds in Natura 2000 a most useful test ground for strategies, as well as for different environmental ethics (see Rosa & Silva, 2005), which may help define its full potential as an instrument for sustainability. In the long term, once the identification of workable sustainable practices and the necessary change of institutional, economic and social paradigms which a successful Natura 2000 would imply in the designated areas have occurred, it is optimistically hoped that Natura 2000 may be allowed to expand beyond itself.…”
