City and biodiversity

Climate change and biodiversity constitute the main challenges of this century. If many human activities contribute to this situation, our way of building and living in the city is the main culprit for this double crisis. Thus, according to UN-Habitat, cities are the source of more than three quarters of global energy consumption (78%) and are responsible for more than 60% of greenhouse gas emissions. The challenges, perspectives and Examples of success which relate to the city’s link with biodiversity will thus be covered. Particular attention will be paid to the challenges to be met as well as the objectives to be achieved at the city level in 2050. Experiences from concrete cities which share their know-how and other useful lessons for planning will finally be provided in order to reach a conclusion on the issues and trajectories highlighted in this document.
