The Republic of Korea‘s spatial planning system has evolved since the 1960s in response to rapid urbanization and economic growth. This monograph examines the key legal and institutional changes, the division of roles between central and local governments, and the tools used for land management and development. It also addresses challenges in implementing planning policies and draws practical lessons for Latin America and the Caribbean (LAC).By 2020, Koreas population reached 52 million, with a 91.8% urbanization rate. Initially focused on building infrastructure, planning has shifted toward sustainability, digitalization, and balanced regional development, guided by laws like the Urban Planning Act (1962) and the National Land Planning and Utilization Act (2003).The monograph highlights Koreas flexible planning approach, strong national leadership, and the use of geospatial technologies, offering valuable insights for LAC countries to improve their own spatial planning and foster balanced development.
