by Kelly April Tyrrell, UW Communications Expansion of cattle pastures has led to the destruction of huge swaths of rain forest in Brazil, home to the world’s largest herd of commercial beef cattle. But a new study led by the University of Wisconsin-Madison’s Holly Gibbs shows that market-driven “zero deforestation agreements” have dramatically influenced the […]
by Kelly Tyrell, UW Communications As with rivers, civilizations across the world rise and fall. Sometimes, the rise and fall of rivers has something to do with it. At Cahokia, the largest prehistoric settlement in the Americas north of Mexico, new evidence suggests that major flood events in the Mississippi River valley are tied to […]
Clearing grasslands to make way for biofuels may seem counterproductive, but University of Wisconsin-Madison researchers show in a recent study that crops, including the corn and soy commonly used for biofuels, expanded onto 7 million acres of new land in the U.S. over a recent four-year period, replacing millions of acres of grasslands.
by Kelly April Tyrrell, UW Communications Today, fewer chicken nuggets can trace their roots to cleared Amazon rain forest. In 2006, following a report from Greenpeace and under pressure from consumers, large companies like McDonald’s and Wal-Mart decided to stop using soy grown on cleared forestland in the Brazilian Amazon. This put pressure on commodity […]
Geography PhD candidate Cathy Day has been awarded a National Science Foundation grant for her dissertation research. Day’s interests center around how climate change influences agricultural systems and how humans perceive and deal with climatic shifts within a complex social-economic context. For her master’s degree, she researched the vulnerabilities of farmer livelihoods to climate change in Niger’s […]
Two UW-Madison Geography graduate students have received 2014-15 Fulbright-Hays Doctoral Dissertation Research Abroad Program awards by the U.S. Department of Education. Both recipients are conducting research in Thailand under Dr. Ian Baird. Starting early next year, David Chambers will look at changing understandings of “good space” among some Hmong ethnic minority communities in northern Thailand. His […]
Researchers say they looked at the combined effects of land use decisions and climate change because, while there are many studies of each, the two factors need to be examined together. As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land. Researchers […]
NSF Science Now spotlights the soil carbon research of Profs. Erika Marín-Spiotta & Joe Mason and former Ph.D. student, Nina Trautmann Chaopricha. For more about their recent research findings, see this related article.
by Terry Devitt, UW Communications Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle. The finding, reported May 25, 2014 in the journal Nature Geoscience, is […]
by David Tenenbaum, UW Communications The University of Wisconsin-Madison, home of pioneering ecologists who studied lakes, forests, wetlands and prairies, is playing a key role in the next wave of ecological research: large teams of scientists confronting the dilemma of a changing climate on a shrinking planet. But where UW-Madison’s Edward Birge and Chancey Juday, […]
