Open spaces are key to the health and vitality of cities. Walkable, safe, green spaces increase the possibilities for people to meet and nurture relationships beyond family, friends, and colleagues. But a discussion about Sharing Cities can't focus on open spaces alone. Gentrification should be a part of that discussion. If we, promoters of Sharing Cities, do not manage to address the tension of gentrification by finding strategies to secure the livelihoods of the people who produce the urban commons and to disarm profit-maximizing interests, then the tragedy of the urban commons will only be reinforced. The way the sharing economy discourse was co-opted by profit-oriented platforms shows how quickly Sharing Cities could fall over the barrier and become just another way to reproduce existing patterns of domination.
How can we share power to make more equitable cities? How much informality and disobedience may be required to enable Sharing Cities? Those are unusual questions that we would like you to keep in mind in order to critically evaluate the examples we have selected. —Adrien Labaeye
1. Bottom Road Sanctuary: A Post-Apartheid Community Managed Nature Sanctuary
The area around Zeekoevlei lake, in South Africa, has had extremely high concentrations of threatened native plant species. This is partly because its northern bank was used as a garbage dump for many years. Then, in 2005, the city of Cape Town rezoned the area into parcels of land to be purchased by people who su ered through the Apartheid. The residents who moved in joined forces with nature conservation officials and local environmental organizations to restore the wetland. In practice, this meant residents largely left the space open and undeveloped. Some residents have actively removed invasive species, allowing a particularly threatened plant species, the fynbos, to thrive again in its natural habitat. The Bottom Road Sanctuary now has over 50,000 native plants, attracting many kinds of wildlife. It also has walkways, benches, and barbecuing spaces for nearby residents to share. —Adrien Labaeye
2. Begum Bazaar, a Self-regulating 'High-Street'
The city of Hamburg decided to tear down a deteriorating historical building complex in a neighborhood once known as "das Gängeviertel." In August 2009, artists formed a collective to oppose the destruction of the 12 buildings, and advocated that they instead be repurposed as a public space for creativity. The collective succeeded in saving the Gängeviertel and held a launch celebration. The event brought 3,000 residents of Hamburg into the space for exhibitions, film screenings, concerts, and other cultural events. The collective then transformed into a cooperative in 2010, and presented a concept plan for the complex to the local urban development authority in Hamburg. The city approved the plan and granted the co-op's use and management of the buildings. In the six years since, several of the buildings have been renovated by the city and tens of thousands of people have visited the cultural complex. In 2012, the German UNESCO Commission celebrated the Gängeviertel initiative as a successful example of urban development that promotes cultural and social participation through the preservation of public spaces and democratic city policies. —Adrien Labaeye
3. Chisinau Civic Center: Vacant Lot Reclaimed as a Public Park for Community Gatherings
A neglected plot of triangular land once lay in the city of Chisinau in Moldova. Cars regularly drove over it. Some used it to dump their garbage and construction rubble. Now, the site is a lively public space, known as the Chisinau Civic Center. The transformation was initiated by the local nongovernmental organization — the Oberliht Association, and was created together with local officials as well as artists, architects, scientists, students, and community members. In the very beginning, they held a public picnic at the park as a way to invite nearby residents to get involved in the park's restoration. The organizers then built a wooden platform in the center of the park with support of the nearby residents. This eventually led to the Civic Center becoming a play area for children, as well as a place for community gatherings, film screenings, games, exhibits, and performances. —Cat Johnson
