Model helps explore patterns of urban sprawl and implicaitons for quality of life

21.02.2007
Americans like living in cities, and according to statistics in the United Nations World Population Database so do an increasing number of people throughout the world.

About 81 percent of the United States’ population now lives in urban areas, as does almost half of the world’s total population. Scientists and engineers say that as the trend continues there’s increasing urgency for societies to learn how to develop more sustainable urban environments.

Among them is John Crittenden, a civil and environmental engineering professor in Arizona State University’s Ira A. Fulton School of Engineering. Crittenden will give a presentation entitled "Decision Support for Urban Development: Integrating Air Quality, Material and Energy Flows, and Social Justice," on Feb. 19 at the annual meeting of the American Association for the Advancement of Science (AAAS).

Crittenden will showcase a model he devised with ASU colleagues to predict patterns of urban sprawl and their implications for natural systems and quality of life for city-dwellers.

Using various social and environmental simulations (i.e., urban growth simulation, ground-level ozone simulation), the model is designed to forecast what the Phoenix metropolitan area might look like in 2015 based on projected development, and then determines many of the potential effects of that growth.

The model is intended to be used as a decision-making tool for local and state governments, civil engineers, business leaders and home owners who want to plan for growth that will avoid negative environmental consequences and protect the quality of life.

"This is really a first attempt to link social decision-making with construction methods and materials with the evaluation of local, regional and global impacts of those choices," Crittenden said. "We could reduce negative regional and global impacts of development by looking at alternative land-use patterns, construction methods and construction materials."

The AAAS annual meeting is the largest scientific conference in the United States, drawing experts and media from around the world to discuss contemporary issues in the field of science.

This year’s theme, "Science and Technology for Sustainable Well-Being," reflects the growing concern in the scientific community and among the general public about issues such as loss of biodiversity, unequal living standards throughout the world, weather-related disasters, proliferation of nuclear weapons and overdependence on petroleum.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
