Between Green and Grey: Towards a New Green Volume Indicator for Cities

Trees in urban settings have vast and documented benefits for city dwellers. We propose that to represent city green the green volume should be taken into account, instead of surface or number of trees. In addition, green volume should be seen in relation to the built “grey” volume to account for dilution or misrepresentation effects. This paper is a first contribution to develop tree-to-buildi...

Large cities are less green

We study how urban quality evolves as a result of carbon dioxide emissions as urban agglomerations grow. We employ a bottom-up approach combining two unprecedented microscopic data on population and carbon dioxide emissions in the continental US. We first aggregate settlements that are close to each other into cities using the City Clustering Algorithm (CCA) defining cities beyond the administr...

Towards a social approach to digital cities

The paper discusses the strategy followed in a digital cities project named Gaia Digital. This project is an ongoing threeyear project sponsored by the Portugal Digital Initiative, within the Information Society operation program framework. It provides a digital city counterpart for Vila Nova de Gaia, a Portuguese town with around 288.000 inhabitants, considering 2001 figures. The Gaia Digital ...

Technological Change and Cities

The United States is in the midst of a technological revolution, driven in large part by rapid advances in microelectronics. There has been much speculation about the impacts of the “information superhighway” on society as a whole, but surprisingly little is known about the potential effects of this technology revolution on the spatial distribution of jobs and people either broadly or in urban ...
