Urban parks can be the future green engines of a self-sufficient urban environment. A productive landscape merges nature for pleasant city escape, with a resource-efficient milieu. The implementation of sustainable ecosystems of community self-organisation into new strategic planning, integrates community supported urban farming, with the production of renewable energies, water purification and waste management. This productive landscape strengthens personal and community responsibility, it is a platform for individual creativity, and social organisation. The workshop searches how urban and landscape design may establish the main catalyst strategies for the generation of a self-sustained green space. Tres Turons Park is a strategic green space with a surface of 122 ha, in the city of Barcelona. It includes Park Güell, part of the UNESCO world heritage. The workshop evaluates how a community self-organised productive landscape can embrace existing historical sites, bringing into dialogue different landscape design approaches.
