Transformational change in urban areas is crucial to reversing biodiversity loss and tackling climate change. Cities are increasingly experiencing ecological degradation, often made worse by the effects of climate change with rising temperatures and more extreme weather. It is widely agreed that the biodiversity and climate crises are inseparable and must be solved together

This report from Arup and C40 Cities defines urban rewilding as restoring natural habitats and their processes in urban spaces, working towards a state of human-nature coexistence. Both large scale and targeted urban rewilding projects are key to fighting biodiversity loss and mitigating the impacts of climate change while promoting human health and well-being.  

Cities can use this report to inspire and engage residents and other stakeholders on the opportunities and benefits that urban rewilding can deliver.
