citytocity

CitytoCity is a concept and network framework used to describe structured exchanges between cities aimed at shared urban learning, policy transfer, and joint action on common challenges. It is not a single organization, but rather a pattern of city-to-city collaboration in which city governments, regional authorities, and affiliated institutions participate through formal or informal arrangements.

Origin and scope: The term gained traction in policy discussions in the 2010s as cities sought to collaborate beyond traditional sister-city ties. CitytoCity emphasizes peer-to-peer learning, data-informed decision making, and scalable pilots across borders or regions.

Structure: CitytoCity networks are typically hosted by a neutral platform or consortium and facilitated by a rotating governance body. Member cities contribute case studies, data, and expertise, while a central platform curates learning materials, best practices, and toolkits. Projects often involve joint research, shared procurement for sustainable infrastructure, climate resilience planning, and mobility innovations.

Activities: Exchanges of officials and practitioners; joint pilots in areas such as urban mobility, energy efficiency, housing, and disaster risk management; open data portals; collaborative policy labs; and mutual aid arrangements during emergencies.

Impact and evaluation: Benefits cited include faster deployment of pilots, broader dissemination of innovations, and strengthened diplomatic ties at the municipal level. Challenges include governance complexity, data privacy, funding, and ensuring equitable benefits across cities of different sizes.
