This report examines the implementation of nature-based solutions (NbS) for municipal stormwater management in Sweden. It finds that while NbS principles are widely embedded in municipal planning, they are rarely called by that specific name. Key barriers to adoption include a lack of standardized cost data—especially for operations and maintenance—and a failure of policy frameworks to fully account for the multiple co-benefits of NbS. The report recommends standardizing cost libraries, clarifying stakeholder responsibilities, and broadening the focus of co-benefits to include heat island reduction and carbon sequestration.

This executive summary describes a scoping study on Ecosystem-based Flood Risk Management in five Sub-Saharan cities: Accra, Cape Town, Durban, Nairobi, and Mombasa. It evaluates the integration of nature-based solutions (NbS) and Ecosystem-based Adaptation (EbA) alongside traditional grey infrastructure to address urban flooding exacerbated by climate change, rapid urbanization, and poor urban planning.

The report argues that government efforts to limit flood risk through natural infrastructure are consistent with fiduciary responsibilities and good governance. It identifies a need for frameworks to guide the selection of natural infrastructure over grey infrastructure and notes that Canada faces increasing flood risks from fluvial, pluvial, and coastal sources.

This report by the African Centre for Cities at the University of Cape Town examines flooding risks in Cape Town's informal settlements, specifically in the Philippi area, and along its coastline. It highlights the intersection of apartheid-era spatial planning, poverty, and climate change, arguing that technical engineering solutions must be paired with collaborative governance and community participation to be effective.

This working paper examines the relationship between urban expansion and the loss of natural infrastructure (blue-green cover) across India's 10 most populated cities between 2000 and 2015. Using remote sensing and satellite imagery, the study highlights how increased paved surfaces lead to reduced groundwater recharge and higher flood risks, recommending an integrated urban blue-green approach to planning to increase resilience.

This fact sheet from the World Resources Institute examines the increase in heavy precipitation in the United States since the late 1950s, attributing the trend to human-caused climate change and detailing the resulting impacts on infrastructure, health, and agriculture.
