Drought Alters Recovery of Rocky Mountain Forests After Fire

University of Wisconsin-Madison

A changing climate is altering the ability of Rocky Mountain forests to recover from wildfire, according to a new study published in the journal Global Ecology and Biogeography. When warm, dry conditions lead to drought in the years following fires, it impedes the growth and establishment of vulnerable new post-fire seedlings. The study also shows that forest recovery has been negatively affected by increased distances between burned areas and the sources of seeds that typically replace trees lost to fire.

Droughts Hit Cereal Crops Harder Since 1980s

McGill University

Drought and extreme heat events slashed cereal harvests in recent decades by 9% to 10% on average in affected countries – and the impact of these weather disasters was greatest in the developed nations of North America, Europe and Australasia, according to a new study.

Declining Snowpacks May Cut Many Nations' Water

Newswise Review

Gradual melting of winter snow helps feed water to farms, cities and ecosystems across much of the world, but this resource may soon be critically imperiled. In a new study, scientists have identified snow-dependent drainage basins across the northern hemisphere currently serving 2 billion people that run the risk of declining supplies in the coming century. The basins take in large parts of the American West, southern Europe, the Mideast and central Asia. They range from productive U.S. farm land to war-torn regions already in the grip of long-term water shortages.

Trees Tell Story of Regreening of West African Grasslands

South Dakota State University

Regrowth of trees explains why grasslands in western Africa known as the Sahel have recovered after devastating droughts in the 1970s and 1980s, according to South Dakota State University professor Niall Hanan. “Studies in the past have suggested that the Sahara Desert was marching southward,” noted Niall, but the study refutes this notion. “Our results show the resilience of the Sahel, with much of the area getting greener and responding better to rainfall.”

MSU Faculty Research Shows California Levees’ Vulnerability

Mississippi State University

With the ongoing extreme drought in California posing a threat to the state’s levee systems, there is an urgent need to invest in research regarding the vulnerabilities of critical infrastructure under extreme climatic events. Mississippi State University Assistant Professor of Civil and Environmental Engineering Farshid Vahedifard and his coauthors warn that current drought conditions pose “a great risk to an already endangered levee system” in a letter published Aug. 21 in Science magazine.
