Colonial New Delhi was planned as a garden city. The subsequent era of planned development by the Delhi Development Authority saw the creation of an extensive hierarchical park system. This is a 'Garden in cities' approach. The problem of unsustainable urban growth trends is now beginning to engage the attention of planners and city manners. Delhi is a city-state with complex land use and land ownership pattern, urbanizing rapidly with severe pressure on land. This study considers how the cooperation of several agencies - planning, civic, infrastructure, land owing agencies, entities, and individuals would be essential to bring about the enhancement of green cover and in developing the connectivity corridors through the concrete jungle.
Geonomy and the Articulation of the Built Environment with the Biosphere: How to Achieve Ecological Balance of Life in Our Cities View Digital Media
Paper Presentation in a Themed Session Salima Bellili
The built environment is a component of urban and architectural laws. In a context of protection of our living environment, other urban laws must complement the regulation of urban design. Where, building materials must provide interactions with the living world at the square micrometer! What are the new scientific approaches that Bio-Urban technology offers? In order to allow a built environment a complicity by complexity of the cohabitation of the living and the articulation of micro-organisms in the urban design, according to new urban laws in application of the theory of urban relativity for the installation of new urban components in an ecological built environment and conducive to a close urban component that is integrated in symbiosis with nature. Will this built environment merge with nature? Will nature be receptive and expectant to this built environment? Are there examples from around the world? How can an urban component be diluted with nature and become an essential ecological living environment? Is biomimicry one of the solutions and how? How should the articulation between urbanism and biology in a built environment be?
Featured Distribution Urban Public Spaces Among Riyadh Residential Neighborhoods View Digital Media

Urban Open Space (UOS) promotes community health including daily activities, but these resources may not available, accessible enough, and or equitably distributed. This paper measures and compares spatial equity of the availability and accessibility UOS among low, middle, and high-income neighborhoods in Riyadh city. The measurement methodology for the UOS availability was by calculating the total of UOS with respect to the population total (m2/inhabitant), and the accessibility indicter by using walking distance of a 0.25 mi (0.4 km) buffering streets network. All UOS were mapped and measured using geographical information systems. To evaluate the significant differences in UOS availability and accessibility across low, medium, and high-income Riyadh neighborhoods, we used a One-way ANOVA analysis of covariance to test the differences. The findings are as follows; finding, UOS availability was lower than global standers. Riyadh has only 1.13 m2 per capita of UOS, the coverage accessible area by walking distance to UOS was lower than 50%. The final finding, spatial equity of the availability and accessibility, were significantly different among Riyadh neighborhoods based on socioeconomic status. The future development of UOS should be focused on increasing urban park availability and should be given priority to those low-income and unhealthy communities.
Progress on Convivial Greenstreets Research in the Contemporary City View Digital Media
Paper Presentation in a Themed Session Ken Tamminga
Streetside gardening is an informal, resident-initiated activity undertaken in dense urban areas in many cities globally. We use the term convivial greenstreets (CG) to connote yardless city streets with a high incidence of residents engaged in neighborly, and potentially socially transformative, horticulture along sidewalks and facades. Our investigations in select western European and U.S. cities suggest that measurable social and ecological benefits may be found where CGs are most intense. To better understand the spatial distribution and urban morphology associated with CGs, our inquiry spanned several phases. First, we located and inventoried CGs in a dozen European cities. From this we devised a greenstreets typology based on land use, street morphology, horticulture density, and related on-site activities. We then selected neighborhoods in Delft, The Netherlands and Philadelphia, USA in formulating a GIS-based Convivial Greenstreet Intensity (CGI) index to provide a consistent method for mapping and comparing CG metrics between cities. And most recently, we conducted questionnaire surveys in two Philadelphia neighborhoods to assess CG gardener practices and compile resident and passersby opinions on the phenomenon. What is emerging is a picture of a spontaneous and pan-urban ecology that appears to provide many benefits with relatively few drawbacks. We conclude by suggesting that CGs may be contributing to the reconciliation of civil society and natural processes in these neighborhoods, and recommending them for further inquiry in urban policy, ecology and sociology.
