How Ameriflux Helped Determine the Impact of the 2012 U.S. Drought on the Carbon Cycle

In 2012, the United States experienced the warmest spring on record followed by the most severe drought since the Dust Bowl. A team of scientists used a network of Ameriflux sites to map the carbon flux across the United States during the drought.

Autonomous Cloud Seeding Aircraft Successfully Tested in Nevada

A team of Nevada scientists and unmanned aircraft systems (UAS) engineers have successfully flight tested the first-ever autonomous cloud seeding aircraft platform. Cloud seeding flare tests were deployed from Drone America’s DAx8 UAS aircraft flown in Reno in late January.

Drought Alters Recovery of Rocky Mountain Forests After Fire

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

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

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.

California 2100: More Frequent and More Severe Droughts and Floods Likely

A study published in Nature Communications suggests that the weather patterns known as El Nino and La Nina could lead to at least a doubling of extreme droughts and floods in California later this century.

Trees Tell Story of Regreening of West African Grasslands

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.”

UCI Study Finds Dramatic Increase in Concurrent Droughts, Heat Waves

Droughts and heat waves are happening simultaneously with much greater frequency than in the past, according to research by climate experts at the University of California, Irvine. Their findings appear today in Proceedings of the National Academy of Sciences.

Company Developed Through University Technology Incubator Helps Ranchers Reduce Water-Related Costs, Addresses Global Water Insecurity

Lisk-Sloan-Spencer.jpg

Remote Well Solutions, which produces fully automated, off-grid water pumping systems that allow ranchers to reduce costs related to time, fuel, water and maintenance, is one of 12 companies from around the United States – including three from New Mexico – to be selected for the Village Capital Water US 2015 program. The six-month program aims to support entrepreneurs in addressing global water insecurity issues through technology.
