- Emerging independent nations

In the aftermath of World War II, governments strive to become architects of a new world order. Under the Marshall Plan, Western Allies undertake the reconstruction of Europe with an eye toward economic recovery, while the Soviet Union focuses on centralized planning. Former colonies and dependencies emerge as independent nations; multilateral and bilateral lending and technical assistance organizations are built to assist them.
New town planning dominates the urban development agenda, along with interest in modern building materials and pre-fabricated construction. Population growth leads to rapid urbanization, and new public sector systems designed to manage planning and development are overwhelmed. Squatter and informal settlements begin to proliferate.
The idea of slum upgrading takes root (John Turner, Peru), but the needs of low-income migrants flowing into the cities are largely overlooked. Master plans based on Western standards are overtaken by unregulated housing built without regard to water, sanitation, and essential services.
