With climate change impacts increasingly affecting cities, the C40 Cities Climate Leadership Group (C40) is implementing a global project, supporting their member cities in assessing their climate safeguarding. This is a key step in building climate-resilient cities with a low carbon footprint and ensuring sustainable development.

Under this project, OneWorld was contracted to develop a methodology that C40 member cities can use to undertake self-assessments of their solutions to safeguard against flood damage.

OneWorld developed the self-assessment methodology, for use across C40 member cities. The methodology enables gauging the impacts of flood management actions and facilitate decision-making in safeguarding these cities from floods. The methodology was tested with two African cities, to provide lessons learned and best practices for broader application
