The future of humanity is an urban future—by 2050, up to 70 percent of the world’s population will reside in cities. As cities grow and the global climate warms, these billions of urban people face increasing threats from air and water pollution, sea-level rise, and urban heat. But it doesn’t have to be this way. Far from being antithetical to urban development, nature offers tangible benefits for city residents and increases cities’ resilience. This series, created in partnership by ICLEI and The Nature Conservancy, makes the case for investing in nature-based solutions and explore mechanisms to leverage the funding and political will for such investments. By investing in nature now, we stand to build a better world for cities and nature tomorrow.
