Cities across Asia and the Pacific have long been planned around an assumed “universal user” who is typically male, able-bodied and economically mobile, contributing to unequal access to transport, public space, services and economic opportunities for women, persons with disabilities, older persons and other marginalised groups. As the region’s urban population is projected to reach 3.4 billion by 2050, substantial new infrastructure and upgrading will be required, creating a critical opportunity to embed inclusion from the outset. This policy brief examines the importance of integrating Gender Equality, Disability and Social Inclusion (GEDSI) into urban planning across Asia and the Pacific. Drawing on regional policy frameworks and practical experiences from cities, it highlights persistent gaps between policy commitments and implementation. The brief emphasises that GEDSI should be treated as a core principle of urban governance and investment, helping cities become more accessible, equitable, resilient and liveable for all residents.
