Browse resources on green infrastructure and other nature-based solutions – cost-effective approaches to prepare cities for climate change impacts.
Improving urban resilience is critical for cities to cope with climate-related extreme weather events and natural disasters. Nature-based solutions and green infrastructure provide cost-effective and resource-efficient approaches that increase a city's capacity to respond to disasters and shocks. Nature-based solutions, such as planting trees to improve urban air quality, revitalizing unused or contaminated land into parks, greening roofs to reduce buildings energy use, and restoring degraded wetlands to mitigate flooding, are increasingly implemented in urban areas to enhance urban resilience.
State of Finance for Nature in Cities 2023
In this publication, UNEP and the Penn Institute for Urban Research outline gaps and opportunities for financing Nature-based Solutions in cities, best practices from around the world, and actions that can be taken to scale up investments in nature.
Better Forests, Better Cities
This report evaluates how forests both inside and outside city boundaries benefit cities and their residents, and what actions cities can take to conserve, restore and sustainably manage those forests.
The Potential for Nature-Based Solutions Initiatives to Incorporate and Scale Climate Adaptation
This paper explores how existing NbS initiatives can better incorporate climate adaptation. It investigates the barriers these initiatives face, as well as new opportunities and lessons learned in implementation.
Biodiversity in UrbanShift Cities
These online reports, with interactive maps and figures, provide indicators to measure the state of biodiversity in UrbanShit cities based on comparable global datasets.
BiodiverCities by 2030
This report provides a vision for cities of the future and the needed systemic shifts to develop "BiodiverCities" that place nature at the heart of decision-making and infrastructure investments.
Beating the Heat
This handbook was launched at COP26 and provides case studies from cities around the world that demonstrate how to sustainably tackle the urban heat island effect.
Smart, Sustainable and Resilient Cities
This working paper investigates the potential of nature-based solutions to help build smart, sustainable and resilient cities, drawing from the experience of G20 countries and beyond.
Addressing Finance and Capacity Barriers
This paper advocates for cities to adopt nature-based solutions through evidence-based arguments and case studies of cities across the globe.
Adaptation Data Explorer
This interactive tool allows urban leaders to understand regional and city-specific climate risks and learn about actions being taken in response.
