To Forecast Winter Rainfall in the Southwest, Look to New Zealand in the Summer
University of California, Irvine

El Niño was long considered a reliable tool for predicting future precipitation in the southwestern United States, but its forecasting power has diminished in recent cycles, possibly due to global climate change. In a study published today in Nature Communications, scientists and engineers at the University of California, Irvine demonstrate a new method for projecting wet or dry weather in the winter ahead.

University of Vienna

An international consortium under the lead of the non-profit organization "International Crops Research Institute for the Semi-Arid Tropics" (ICRISAT) and participation of a research team around the system biologist Wolfram Weckwerth has published the genome sequence of Pearl millet, a drought resistant crop plant most important in aride regions in Africa and Asia. This so-called C4 plant is especially important to small and medium farmers who grow the plant without larger irrigation. Pearl millet delivers a good harvest index under drought and heat conditions when rice, maize or wheat already have no grains anymore.

Extension experts can provide an irrigation audit, which will help you troubleshoot spots where perhaps the sprinklers are not wetting the soil uniformly. It may be tempting to run the sprinklers more often when we see dry spots in the lawn, but the problem may be more related to how uniformly the sprinkler heads are covering the lawn than to the amount of time they run.

Game Theory Shows How Tragedies of the Commons Might be Averted
Georgia Institute of Technology

Lake Lanier in Georgia is the primary water reservoir serving suburban and metropolitan Atlanta. When the lake’s water level drops below a certain point, calls go out for water conservation and news reports show images of the red mud shoreline. In some affected counties, water restrictions are imposed. The combination of usage restrictions and changes in precipitation eventually averts the crisis. But, when the crisis ends, water usage rebounds – until the next shortage.

Drought Stalls Tree Growth and Shuts Down Amazon Carbon Sink, Researchers Find
University of Exeter

A recent drought completely shut down the Amazon Basin's carbon sink, by killing trees and slowing their growth, a ground-breaking study led by researchers at the Universities of Exeter and Leeds has found. Previous research has suggested that the Amazon -the most extensive tropical forest on Earth and one of the "green lungs" of the planet -- may be gradually losing its capacity to take carbon from the atmosphere. This new study, the most extensive land-based study of the effect of drought on Amazonian rainforests to date, paints a more complex picture, with forests responding dynamically to an increasingly variable climate.

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.

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.”
