Despite an increasing interest in issues surrounding environmental equity, much research evidence to date is based on studies adopting cross-sectional approaches which do not adequately capture the processes and mechanisms generating inequities. Longitudinal studies may better inform policy measures to remedy inequity between populations, but the few that have been undertaken have mostly been focused solely on environmental risks—ignoring access to amenities. As a case study, we adopt a longitudinal approach in this work to investigate the association between sociodemographic indicators and public
park provision over an eighteen-year period in the city of Yokohama, Japan. We show that inequities in park provision are present over the whole time period. Hedonic modelling shows that park accessibility is positively associated with house and land prices in the city. Our results suggested some, relatively weak, evidence of two causal processes: new parks are located in more affluent communities; yet new parks also appear to encourage further move-in of affluent populations. We suggest that park provision by administrative authorities in less-affluent neighbourhoods may be required to maintain equity in access
to these valuable community resources. Economic incentives, such as subsidy provision, may have a role to play to encourage park provision by developers.
This paper looks at new, high-profile redevelopment projects in Tokyo and New York City and their surroundings for examples of trends in the design of urban public spaces and changing patterns in how they are used. This includes new parks and other open spaces, landscaped plazas or public squares associated with new office towers, shopping centers and other largescale commercial developments, and various popular “festival sites” such as those along recreation waterfronts. A comparison indicates that both cities have quite a few new public spaces that enhance the quality of urban life and add aesthetic appeal, but that also reflect certain social problems and divisions. We see the following common trends: (1) increasing privatization of spaces that were once more clearly in the public domain; (2) increasing surveillance of public spaces and control of access to them in order to improve security; and (3) increasing use of design themes that employ “theme park” simulations and break connections with local history and geography. In the Tokyo area there is also a curious trend to create large, landscaped open areas near new development projects that few people use. They can be called “planned wastelands” or “new urban deserts”. New York City, on the other hand, has succeeded in having more people come together for enjoyment in parts of the city that were once all but abandoned. The paper is illustrated with photographs, and draws on the examples of Times Square, South Street Seaport and Battery Park City in New York, and Yebisu Garden Place,
Teleport–Daiba, Makuhari New Town and Minato Mirai 21 in the Tokyo–Yokohama area.
