Greater desertification control using sand trap simulations
A new simulation will help improve artificial sand-control measures designed to help combat desertification.
Is desertification on the increase?
Fighting desertification will require a better understanding of its drivers of this process, with a little help from a new tool to study how dry regions evolve
Two thirds of Chile faces desertification
Two thirds of Chile's territory is facing desertification in which the bone-dry Atacama Desert grows by over a meter (3.3 feet) a day, President Sebastian Pinera warned.
Land degradation causes up to 5% loss in farm output
Loss of land through desertification and drought costs up to five percent of world agricultural gross domestic product (AGDP), or some $450 billion (340 billion euros), every year, said a study presented ...
From grasses to shrubs: How plants reinforce desertification
(Phys.org)—Research into how fragile dryland ecosystems degrade into deserts has revealed that the transition from grasslands to desert shrubs may be reinforced by the plants themselves. The study, conducted ...
Some plants in arid regions benefit from climate change, study finds
(Phys.org)—Dryland ecosystems cover 41% of the Earth's land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive ...
Drastic desertification: Researchers study Dead Sea climate past, finding dramatic results
Over the past 10,000 years, climate changes in the Dead Sea region have led to surprisingly swift desertification within mere decades. This is what researchers from the University of Bonn and their Israeli colleagues found ...
Landmark Rio summit on 'green' economy opens
World leaders open a UN summit Wednesday where they are set to endorse a blueprint for eradicating poverty and protecting the environment that critics insist is a threadbare compromise.
Many questions as Rio Summit seeks to help sick planet
Twenty years ago, a burst of sunny optimism radiated from Rio de Janeiro as world leaders staged a meeting that would prove pivotal.
Fossilized plant matter points to desertification near Tibetan Plateau
Roughly 22 million years ago, at the onset of the Miocene, the Tibetan Plateau started to lift upward. The rising land curbed the flow of moist air from the south, sparking the onset of central Asian desertification. Or, ...
Sprawling and powerful 'community models' shaping future of regional and global science
Since the dawn of science, scientists have been using models to visualize and explain the workings of the world. But where the earliest ideas might have been conveyed in something as simple as a cave painting, modern-day ...
Diverse ecosystems are crucial climate change buffer
Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.
Gum arabic potential cure for Sudanese ills
Since he was 14, Al-Amin has tapped gum arabic, the resin of an acacia tree that thrives in Sudan's conflict states -- "manna" from heaven for some, a key ingredient in Coca-Cola for others.
Iran, Iraq pay $1.2 bn to battle sandstorms
