Unit
- Ancient city planning: Early settlements like Mohenjo-Daro and Rome used grid layouts and public spaces to organize civic life, establishing principles of order and hygiene that influenced later urban forms.
- Industrial revolution impact: Rapid urbanization in the 19th century created overcrowded, unsanitary slums, prompting reformers to advocate for parks, affordable housing, and sanitation systems in city plans.
- Garden City movement: Proposed by Ebenezer Howard in 1898, this concept combined town and country advantages through self-contained communities surrounded by greenbelts, influencing suburban development worldwide.
- Modernism and the Functional City: Le Corbusier and the Congres Internationaux d Architecture Moderne promoted strict zoning, high-rise towers, and separation of functions, later criticized for neglecting human scale and community life.
- Participatory turn: The 1960s saw calls for citizen involvement in planning, as exemplified by Jane Jacobs advocacy for mixed-use, walkable neighborhoods and bottom-up decision making.
- New Urbanism: Emerging in the 1980s, this movement emphasizes walkable blocks, diverse housing, and transit-oriented development as alternatives to car-dependent sprawl.
- Smart growth and sustainability: Contemporary planning integrates environmental goals with compact development, aiming to reduce carbon footprints and enhance quality of life through density and transit access.
- Digital transformation: Geographic information systems (GIS), big data, and computational modeling now allow planners to simulate scenarios, analyze spatial patterns, and engage citizens through interactive platforms.
- Regional planning and the valley section: Patrick Geddes introduced the valley section concept, which ties human settlement patterns to natural geography from mountain to sea. His method stressed comprehensive regional surveying of resources, history, and culture before any planning, profoundly shaping later ecological and regional planning approaches.
- Advocacy and equity planning: In the 1960s, Paul Davidoff argued that planners should advocate for marginalized groups rather than remain neutral. Equity planning, championed by Norman Krumholz in Cleveland, explicitly prioritized redistributive policies to address racial and economic disparities, ensuring fair access to urban resources and opportunities.
- Resilience and climate adaptation: Contemporary urban planning increasingly integrates resilience strategies to address climate change, including flood defenses, green roofs, permeable pavements, and emergency response systems. Planners use risk assessments and adaptive design to protect vulnerable populations and infrastructure, ensuring cities can withstand environmental shocks.
Creative Inspiration
Movement: Garden City Movement
Howard envisioned towns limited to 32,000 residents, arranged around a central park with radial boulevards, industry on the periphery, and agricultural greenbelts. The idea was to offer the benefits of both city and country without their drawbacks.
Modern Application: Contemporary eco-cities and new towns in Asia and Europe draw on Garden City principles, integrating green infrastructure and mixed-use neighborhoods to reduce car dependence and improve livability.
Quick Revision
- Urban planning evolved from ancient grids through industrial reform, modernist zoning, participatory approaches, and current sustainability and digital trends.
- The Garden City movement introduced self-contained, greenbelt-surrounded communities that inspired later suburban and new town developments.
- Modernist planning separated functions but was later criticized for lacking human scale, leading to movements like New Urbanism and smart growth.
- Digital tools like GIS and data analytics are transforming how planners analyze and engage with urban systems.
