Microsoft Research tackles ecosystem modeling

What if there was a giant computer model that could dramatically enhance our understanding of the environment and lead to policy decisions that better support conservation and biodiversity? A team of researchers at Microsoft Research are building just such a model that one day may eventually do just that, and published an article last week in Nature (paid access) arguing for other scientists to get on board and try doing the same.

When Drew Purves, head of Microsoft’s Computational Ecology and Environmental Science Group (CEES) and his colleagues at Microsoft Research in Cambridge, United Kingdom, began working with the United Nations Environment Programme World Conservation Monitoring Center (UNEP-WCMC), they didn’t know they would end up modeling life at global scales. “UNEP-WCMC is an international hub of important conservation activity, and we were pretty open-minded about exactly what we might do together,” says Purves. But they quickly realized what was really needed was a general ecosystem model (GEM) – something that hasn’t been possible to date because of the vast scale involved. In turn, findings from a GEM could contribute to better informed policy decisions about biodiversity.

But first, a primer on terminology. A GCM (general circulation model) is a mathematical model that mimics the physics and chemistry of the planet’s land, ocean and atmosphere. While scientists use these models to better understand how the earth’s climate systems work, they are also used to make predictions about climate change and inform public policy. Because these models have been so successful, members of the conservation community are looking for a model that could improve their understanding of biodiversity.
