The "Green City of the Future" (Grüne Stadt der Zukunft) is a research project aiming to develop knowledge about integrated solutions to meet the challenges of climate change and subsequent densification in Munich, Germany and test how these can be implemented in an urban planning context. The focus is on selected districts of Munich, which face the conflicting goals of green spaces and housing needs. In these areas, an interdisciplinary research team of five working groups investigates how the functions and performance of green infrastructure can be maintained and developed and how climate adaptation requirements can be anchored at various planning levels and processes. The research project started in October 2018 and is funded for 5 years by the Federal Ministry of Education and Research as part of the flagship initiative "Future City". The city of Munich - represented by the Department for Urban Planning and Building Regulations (PLAN) and the Department for Climate and Environmental Protection (RKU) - is part of the project team and acts as practice partner. Furthermore, the city of Munich brought testing sites - so-called 'real laboratories' - into the investigations. The interdisciplinary investigations in the real laboratories had the objective of developing integrated recommendations for planning practice.
