The International Union of Architects (UIA) and the International Federation of Landscape Architects (IFLA) have a long association one with the other. They also have a Memorandum of Understanding providing for engaging together in joint projects. This project for the development of Indigenous Ecosystem Corridors and Nodes provides for such cooperation between the professions. In doing so it also offers an open invitation for the participation of other professions and relevant organisations.
You can find out more about this project, including the establishment of a working group on this matter in the document here.
