USDA Announces Planting of Wheat Stem Rust-Resistant Seed in Afghanistan (Nov 4, 2010)
U.S. Department of Agriculture.
Agriculture Secretary Vilsack announced that 150 tons of wheat stem rust-resistant wheat seed was safely planted in Afghanistan. The seed, which originated from Egypt's Agricultural Research Center as part of a joint effort with USDA and the International Maize and Wheat Improvement Center, is designed to help halt the spread of wheat stem rust that could threaten Afghanistan's most vital staple crop. Worldwide, more than 1 billion people in developing countries count on wheat for their food and incomes. Wheat stem rust can cause up to 100 percent yield loss if left untreated.

New USDA Study Shows Extent of Land Degradation and Recovery on Western Rangelands (Oct 1, 2010)
USDA. Natural Resources Conservation Service.
The U.S. Department of Agriculture released a new study by scientists and conservationists showing that non-federal rangelands in the Western United States are productive, but that non-native grasses and shrubs pose a potential threat to the rangelands' productivity. The study National Ecosystem Assessments Supported by Scientific and Local Knowledge, published in Frontiers in Ecology and the Environment, reveals that less than 25 percent of non-federal rangelands have significant land degradation but that non-native plant species now occur on nearly 50 percent of all non-federal rangeland. While some of these species have significant benefits for soil conservation, others have negative effects.
