What if a plant and hydrological test center becomes a dynamic transition zone between Nature Park Amager and the city, testing the reaction of plants to shifting water levels as well as being a public and social reclamation learning center? How can military traces be the foundation for new site- specific larger urban notes of city and park? And what if the shopping centre Fields is being opened up, and a new public main square across the highway becomes the new centre of Ørestad interlinking Amager north to south, east to west? This catalogue presents strategic development and design proposals for city-nature border conditions on Amager, Copenhagen. From November 2014 to February 2015, 33 students from eight countries with an equal number of foreign and Danish students explored possible solutions for new city-nature border conditions of Amager and Nature Park Amager seeking to unfold the future potentials of Amager and the Nature Park locally and in a greater Copenhagen city context.
