Building the cities we aspire to live in requires integrating all social sectors. Socio-urban integration seeks to reverse urban segregation and social exclusion by improving structural conditions in Argentina’s 6,467 informal settlements and ensuring universal access to a dignified habitat—adequate housing, basic infrastructure, transportation, public spaces, and social services. Argentina has advanced along this path for years. At Fundar, we consider it essential to uphold it as a State policy, while innovating to enhance its scalability.
