Apr 6, 2006Supporting Restoration of the “Garden of Eden”: Mesopotamian Wetlands

Contributor: Jeff Masek The United Nations Environmental Programme (UNEP) has undertaken an assessment of the recent dramatic decline in some unique Mesopotamian marshes, and has relied heavily on Landsat data for their mapping. The Mesopotamian marshes once extended across 15,000 – 20,000 square kilometers.  They are the homeland for the “Marsh Arabs”, Shi’ite Muslims who have […]

Landsat-derived record of increasing urbanization
Apr 6, 2006Planning for Restoration of Chesapeake Bay

Contributor: Scott Goetz After years of scientific research, policy analysis, public education, and substantial sums of money spent, restoration of Chesapeake Bay remains a challenge. Few of the indicators of habitat, fisheries, or water quality show significant improvement, and several show continued decline.  Why is it so difficult to restore this national treasure? People desire to […]

Forest fire

Apr 6, 2006Collaboration for Cancer Research

Contributor: Susan Maxwell Human health scientists have associated cancer, neurological disorders, and adverse reproductive outcomes with exposure to agricultural chemicals. Lack of information on historical environmental exposure to these chemicals, for rural populations in particular, has hampered further study. The U.S. Geological Survey EROS Data Center, the National Cancer Institute, and Colorado State University are collaborating […]
