The journey toward renaturalizing urban spaces is an ongoing effort that began as early as the 1970s and continues to shape cities worldwide today. From transforming highways into vibrant parks to restoring waterways and integrating nature into urban planning, these projects reflect a shared commitment to sustainability, livability, and resilience. In Portland, the 1978 creation of Tom McCall Waterfront Park set a pioneering example by replacing a highway with green spaces. Decades later, Boston followed with the Rose Kennedy Greenway, reclaiming land from the elevated Central Artery.
Across the globe, Seoul's Cheonggye Stream restoration and Barcelona's pedestrian-focused Green Axes initiative illustrate how cities can revitalize public spaces and enhance their ecological footprint. In Europe, Paris and Berlin are leading waterway revitalization projects, while Kongjian Yu's sponge city concept offers a model for addressing climate challenges through natural design. Together, these efforts demonstrate the power of rethinking urban landscapes to harmonize cities with nature and create a sustainable future.
Read on to explore six articles showcasing urban transformations that integrate nature into the urban fabric across cities worldwide.
Urban Waterways Reborn: European Cities Leading the Charge in River Restoration and Revitalization
European cities like London and Berlin are leading urban waterway revitalization to enhance environmental quality and urban livability. Paris is restoring the Seine to become swimmable, and In London, the "Thames Tideway Project" is on a mission to reconnect the city with the River. Meanwhile, Berlin's Flussbad project reimagines a segment of the Spree Canal as a swimmable urban oasis, promoting community engagement and sustainability. These initiatives represent a broader trend of reclaiming natural spaces in cities to foster ecological and social benefits.
Urban Landscape as an Art of Survival: An Interview with Kongjian Yu, the Advocate of the Sponge Cities Concept
Kongjian Yu's sponge city concept offers a unique approach to urban water management, integrating natural landscapes like wetlands and green roofs to absorb and reuse rainwater. Implemented across China, this model has helped mitigate flooding and has been recognized internationally. Kongjian Yu defines urban design as harmony between cities and nature, addressing climate challenges through sustainable and ecological planning.
Re-Naturalization of Urban Waterways: The Case Study of Cheonggye Stream in Seoul, South Korea
Seoul's Cheonggyecheon Stream restoration demonstrates the transformative potential of uncovering urban waterways. Once covered by a highway, the stream was revitalized in 2005, creating a linear park that improved biodiversity, air quality, and public space. The project has significantly enhanced social and economic vitality, drawing tourists, increasing property values, and inspiring similar efforts globally. It showcases how natural elements can redefine urban ecosystems for sustainability and livability.
Towards the Renaturalization of Urban Spaces: How 08014 Arquitectura's Projects Are Reclaiming Barcelona's Streets
Barcelona is transforming its urban fabric by prioritizing pedestrian-friendly and green spaces, with 08014 Arquitectura leading key projects. The Plaza-Jardín Rocafort and Paseo Comte d'Ègara illustrate how vehicular zones are being re-naturalized to enhance accessibility, safety, and community interaction. These efforts align with broader city programs like Green Axes and Superblocks, which aim to reduce traffic and integrate nature into urban environments, creating a more sustainable and livable city.
The Rose Kennedy Greenway: How Boston Unpaved its Way to a Greener City Center
The Rose Fitzgerald Kennedy Greenway in Boston exemplifies urban transformation by converting former highway land into vibrant public spaces. Initiated in 1991 as part of the "Big Dig" project, the endeavor replaced the elevated Central Artery with a linear park that opened in 2008. This greenway reconnects neighborhoods like Chinatown, the Financial District, and the North End, fostering community engagement and environmental sustainability. It features organically maintained gardens, promenades, and art installations, serving as a model for urban renewal and the integration of natural elements into cityscapes.
Transforming Portland: How a Demolished Highway Became a Pioneering Waterfront Park
Portland's transformation of its waterfront exemplifies innovative urban renewal by replacing Harbor Drive, an obsolete highway, with Tom McCall Waterfront Park. Completed in 1978, this 30-acre park reconnected downtown to the Willamette River, offering walking paths, open lawns, and river access. The project marked a significant shift from car-centric infrastructure to prioritizing public green spaces, enhancing urban livability and setting a precedent for similar initiatives worldwide.
