Rebuilding Geoscience in Canada:
Life After Major Budget Reductions
When its funding was cut, the Geological Survey of Canada (GSC) had to ask tough questions about its programs. The GSCís former chief scientist reports on their restructuring process and a new spirit of cooperation between the federal and provincial surveys, industry, and academia.

The USGS Streamgaging Network: Born of Yesterday, Serving Today Ö Poised for Tomorrow?
For more than a century, the U.S. Geological Survey has operated a network of 4,000 streamgaging stations that provides vital data to both resource managers and homeowners. But funding constraints are forcing more and more stations to close. A new report lays out the case for investing in an improved infrastructure.

Geoscience and Geopolitics
Issues of resource exploration, management, and sustainability require global approaches to problem-solving. An international resource-management expert challenges geoscientists to play more active and cooperative roles in addressing such critical problems as nuclear-waste disposal, greenhouse-gas emissions, and water shortages.

The key to better decision-making may be cost-effective, realistic alternatives to prediction.
