city and community level action to be points of alignment between Nationally Determined Contributions, National Adaptation Plans and the SDGs. City and local action can complement, and at times go further than national and international interventions. Similarly, the Convention on Biological Diversity offers a global agreement through which nature-based solutions can be viewed as benefits for biodiversity, social justice and climate resilience. However, there is no specific global agreement that addresses informality and city-level climate adaptation. More comprehensive and clearly articulated global ambitions for city and community adaptation will contribute to inclusive urbanisation, by addressing the root causes of social and economic inequalities that drive social exclusion and marginalisation, so that adaptation can directly support the 2030 Sustainable Development Agenda .
