Thoughts from the World Water Expo

The world’s a pretty big place. So when a group of water resource experts from different parts of the world come together, and all describe the same problems (though seen through different lenses of geography, culture, and language), that’s a notable thing.

That’s what happened at the 2008 World Water Expo in Zaragoza, Spain, where water resource experts from across the globe — including Australia, Israel, Jordan, Spain, South Africa, and the United States — participated in a scientific symposium as a kick-off to the Expo. All invited speakers there spoke of problems with growth, water supply, water quality, and climate disruption. The water resource conditions in the various countries were as varied as the languages spoken, but the underlying problems were the same. Jordan, for example, is arid with a developing economy, whereas Australia is arid with a post-industrial economy — yet both face the same challenges of growth, water supply, water quality, and climate disruption.

Where does the Bay Program fit into this picture? As an invited participant, the Bay Program described our approach of integrating models, monitoring, and research for restoration of the Chesapeake. Our presentation of the linked airshed, watershed, estuarine, and living resource models, along with the supporting and corroborating monitoring observations and research was well-received, and was seen as a world-class example of the information systems needed to support water resources under pressure from population growth, climate change, and past environmental degradation.

All of the invited speakers spoke to problems of growth and water quality. In the Chesapeake, we’ve been working a long time to restore water quality despite growth pressures in our watershed, so these are issues we’re familiar with. But just like in other parts of the world, the issues of providing an adequate water supply and climate disruption are also emerging issues for the Chesapeake. Last year, the city of Fredrick, Maryland, had to curtail construction permits due to concerns over the sufficiency of water supply. This may be a harbinger, because our Chesapeake water supply infrastructure is designed for average annual flows different from the decreased annual flows we may see with future climate change, as the Bay Program has described in presentations at the 2007 American Water Resources Society and the Coastal and Estuarine Research Federation.

At the World Water Expo we saw that the challenges of growth, adequate water supply, water quality, and climate disruption were ubiquitous. The world’s a big place and a watery place. How ironic that we’re all in the same boat.
