"Antelope Perfume" Keeps Flies Away From Cows
October 20, 2017 01:58 PM - University of Bonn

In Africa, tsetse flies transfer the sleeping sickness also to cattle. This leads to huge losses in milk, meat and manpower. The damage in Africa is estimated to be about 4.6 billion US dollars each year. Prof. Dr. Christian Borgemeister from the Center for Development Research (ZEF) at the University of Bonn and his colleagues from Kenya and the UK have developed an innovative way of preventing the disease. The scientists took advantage of the fact that tsetse flies avoid waterbucks, a widespread antelope species in Africa. The scientists imitated the smell of these antelopes. If the cattle were equipped with collars containing the defense agent, more than 80 percent of the cattle were spared from the feared infection. This research results are presented in "PLOS Neglected Tropical Diseases".

Planting trees, restoring peatlands, and better land management could provide 37 percent of the greenhouse gas mitigation needed between now and 2030 to keep global warming to 2 degrees Celsius, according to a new study published in the Proceedings for the National Academy of Sciences.

Living Mulch Builds Profits, Soil
October 18, 2017 10:48 AM - American Society of Agronomy

Living mulch functions like mulch on any farm or garden except — it’s alive. No, it’s not out of the latest horror movie; living mulch is a system farmers can use to benefit both profits and the soil. While the system has been around for a while, scientists at the University of Georgia are making it more efficient and sustainable.

Future Temperature and Soil Moisture May Alter Location of Agricultural Regions
October 18, 2017 08:19 AM - U.S. Geological Survey (USGS)

Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.  

These future conditions will cause an overall increase in the area suitable to support rainfed agriculture within dryland areas. Increases are projected in North America, western Asia, eastern Asia and South America. In contrast, suitable areas are projected to decline in European dryland areas.

Volcanic Eruptions Linked to Social Unrest in Ancient Egypt
October 17, 2017 11:39 AM - Future Earth

Around 245 BCE Ptolemy III, ruler of the Ptolemaic Kingdom in Egypt, made a decision that still puzzles many historians: After pursuing a successful military campaign against the kingdom’s nemesis, the Seleucid Empire, centred mainly in present-day Syria and Iraq, the king suddenly decided to return home. This about-face “changed everything about Near-East history,” says Joseph Manning, a historian at Yale University.
