Impact of Information and Communication Technologies (ICT) in Environmental Sciences: A Citation Analysis 1990-2007

Environmental Modelling & Software, Volume 24, Issue 7, July 2009, Pages 865-871

R. Casagrandi and G. Guariso

“Detecting trends on the use of Information and Communication Technologies (ICT) in the domain of environmental sciences is important to foresee new frontiers of modelling and software research. Here we analyze the impact of ICT in scientific papers published from 1990 to 2007 in all ISI journals and in those belonging to the Environmental Sciences category only. We thus determine some expanding, fluctuating or unexploited research directions. Quite unexpectedly, we find that the frequency of occurrence of many, yet not all, information technologies increased at significantly higher rates in the environmental studies than in the general sciences. We also contrast trends in the EMS journal to those of the entire domain and discuss differences in some details. Retrieving pertinent information for the comparison is certainly made difficult by some inconsistency in the use of keywords and the current lack of semantic oriented tools. Nevertheless, we find that this journal is leading the development on some research topics, like decision support systems or information systems.”

“The objective of this study was to identify spatial variability in exposure to outdoor traffic-related air pollution with specific emphasis on comparing exposure estimates for working females and males across a metropolitan area. A spatial exposure simulation model was used to estimate annual average exposure to traffic-related nitrogen dioxide for males and females reporting regular work in census tracts other than that of their residence, in Vancouver, British Columbia. The model produced estimates of annual average exposure in six microenvironments (home indoor, work indoor, other indoor, outdoor, in-vehicle to work, and in-vehicle other) using time-activity patterns and work flow data, for males and females in each of 382 census tracts. This allowed for the identification of spatial variations in exposure estimates for each gender, due to mobility within the study region. Indoor sources of nitrogen dioxide were not included in the simulation. No significant differences in estimated total exposure were found between working females and males in general. Small but observable spatial differences, however, were found between working females and males at the 90th percentile of the exposure distributions associated specifically with the work indoor microenvironment. These were highest in suburban areas (+3 μ g/m3 for females, relative to total exposures in the range of 26 to 37 μ g/m3 annual average hourly nitrogen dioxide). These results identify specific geographic locations in the study area where personal monitoring studies might be warranted and suggest that the inclusion of workplace locations in multivariate modeling could be useful to further understand differences in estimated exposures.”

A Spatial Analysis of Gullies on Mars

Proceedings of the 41st Lunar and Planetary Science Conference (2010)

“The possibility of life on Mars has intrigued people for over a century. A necessary re-quirement for life is water, a substance confirmed to exist on Mars. Gullies are features typically created by flowing water. Although Mars today is a desert planet, numerous geologically young gullies exist. The pres-ence of these gullies on the surface of other features, such as craters, suggests the gullies are young relative to the features on which they lie [1]. Many images of Martian gullies have been studied and compared to gullies on Earth to try to determine the origin of Mar-tian gullies. A gully is defined as a surficial feature having an alcove above a channel, and channels are typically associated with water [1].”

Disappearing Ducks? North America’s Prairie Potholes Vulnerable to Warming Climates

The loss of wetlands in the prairie pothole region of central North America due to a warmer and drier climate will negatively affect millions of waterfowl that depend on the region for food, shelter and raising young, according to research published today in the journal BioScience.

The new research shows that the region appears to be much more sensitive to climate warming and drying than previously thought.

“The impact to the millions of wetlands that attract countless ducks to these breeding grounds in spring makes it difficult to imagine how to maintain today’s level of waterfowl populations in altered climate conditions,” said Dr. Glenn Guntenspergen, a U.S. Geological Survey researcher and one of the report authors. “Parents may not have time to raise their young to where they can fly because of wetlands drying up too quickly in the warming climate of the future,” he added.

A new wetland model developed by the authors to understand the impacts of climate change on wetlands in the prairie pothole region projected major reductions in water volume, shortening of the time water remains in wetlands and changes to wetland vegetation dynamics in this 800,000-square kilometer region in the United States (North and South Dakota, Montana, Minnesota and Iowa) and Canada.

Many wetland species — such as waterfowl and amphibians — require a minimum time in water to complete their life cycles. For example, most dabbling ducks — such as mallards and teal– require at least 80 to 110 days of surface water for their young to grow to where they can fly and for breeding adults to complete molting, the time when birds are flightless while growing new feathers. In addition, an abundance of wetlands are needed because breeding waterfowl typically isolate themselves from others of the same species.

“Unfortunately, the model simulations show that under forecasted climate-change scenarios for this region (an increase of 4-degrees Celsius), the western prairie potholes will be too dry and the eastern ones will have too few functional wetlands and nesting habitat to support historical levels of waterfowl and other wetland-dependent species,” said Dr. W. Carter Johnson, another study author and a researcher at South Dakota State University.

The authors noted that their model allowed a more comprehensive analysis of climate change impacts across the northern prairies because it simultaneously examined the hydrology and vegetation dynamics of the wetland complex, which are both important for the wildlife that depend on the prairie potholes for part or all of their life cycles.

“Our results indicate that the prairie wetlands are highly vulnerable to climate warming, and are less resilient than we previously believed,” said Guntenspergen. “All but the very wettest of the historic boom years for waterfowl production in the more arid parts of the prairie pothole region may be bust years in a 4-degrees Celsius warmer climate.”

These findings may serve as a foundation for managers and policy makers to develop management plans to prepare for and adapt to climate change in the prairie pothole region.

The article, Prairie wetland complexes as landscape functional units in a changing climate, was published in BioScience (60[2]:128-140) and authored by researchers with South Dakota State University, the U.S. Geological Survey, University of Montana, St. Olaf College, The Desert Research Institute-University of Nevada, and the University of Idaho.
