Located in the centre of the country, the City of Brussels was founded around the year 1000. It is densely populated with 176,545 inhabitants over 32.61 km2 and the population continues to grow quite rapidly. The city is composed of different territories that have been gradually linked to it and that are very different from each other in their social composition. There is an average of 25m2 of green space per inhabitant and an urban forest is developing in the north. This project with others (green facades and roofs, community vegetable gardens and green spaces…) will help to counter the expected effects of climate change-that is, urban heat islands and flooding.
