The sand along the south-western coastal rim of Norway has drifted for more than 9000 calendar years. This was triggered by sea-level changes and human activities, new research has found. Researchers in countries such as Denmark, the Netherlands and Poland study sand drift, but most of them are focusing on sand dunes along the coastline, not on the plains further inland. "Sand dunes are dynamic. For all we know, they may have been formed last year. But sand plaines are much older and in...

According to a study prepared for the environment ministry that was published Tuesday, Spain has warmed at a faster pace than other areas in the northern hemisphere over the past three decades. The study by the Spanish branch of the Clivar research network found that the country has experienced average temperature increases of 32 degrees Fahrenheit per decade since 1975, which is "50 percent superior to the average of nations in the northern hemisphere." The study says that Spain is on...

Experts said at a water conference on Thursday that the desert is making a comeback in the Middle East, with fertile lands turning into barren wastes that could further destabilize the area, according to a recent AFP report. "Desertification spreads like cancer, it can't be noticed immediately," said Wadid Erian, a soil expert with the Arab League, at a conference on Thursday in the Egyptian coastal town of Alexandria. Erian said that the effects could be seen in Syria, where drought...

"Despite improvements in the LCA, it has a methodological weakness, which is a lack of environmental impact categories to measure the effect of human activities such as cultivation or grazing on the soil", Montserrat Núñez, lead author and a researcher at the Institute of Agro Food Research and Technology (IRTA), tells SINC. The research, published in the latest issue of the International Journal of Life Cycle Assessment, is the first study in the world...

Weizmann Institute scientists show that in one kind of forest, its 'energy budget' includes significant reserves of heat The simple formula we've learned in recent years "“ forests remove the greenhouse gas CO2 from the atmosphere; therefore forests prevent global warming "“ may not be quite as simple as we thought. Forests can directly absorb and retain heat, and, in at least one type of forest, these effects may be strong enough to cancel out a good part of the benefit in...

A new scientific organisation is needed to monitor the commitments that will be made by developing countries at Copenhagen to cut their deforestation rates, according to research at the University of Leeds. Existing government agencies and research groups have failed to make full use of the thousands of satellite images of the Earth's surface collected each week to monitor tropical forests. Now, a paper published by Dr Alan Grainger in the Proceedings of the National Academy of Sciences...

Deforestation and overgrazing are among the factors being blamed for turning almost a quarter of India into desert, according to a study published this week. The study's authors report that northern and western India are the hardest hit, as shown by satellite mapping. The study, published by the Space Applications Center and the Current Science journal states, "There has been a long-pending need for desertification/land degradation status mapping of the entire country based on scientific...

Mojave Desert research shows that nitrogen is second only to water in importance In the Mojave Desert winds howl across this hottest place in North America, blowing sands across Death Valley and through empty ghost towns, swirling across treeless land for hundreds of miles. But even in the otherworldly Mojave, life thrives. The Joshua tree (Yucca brevifolia), an indicator species for this desert, defines the Mojave's boundaries. In spring when the rains come, brightly colored flowers bloom in...

With land degradation in dryland regions continuing to worsen, the UN Convention to Combat Desertification has agreed on scientist-recommended indicators for monitoring and assessing desertification that signatory countries must report on. The landmark agreement was reached after two weeks of negotiations involving hundreds of scientists and government ministers attending the Ninth Session of the Conference of the Parties (COP 9) of the UN Convention to Combat Desertification (UNCCD) in...

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Deforestation

Deforestation is the act or process of removing trees from forested lands by cutting or burning. There are many reasons for deforestation. Logs are sold as a commodity and cleared lands can be used for pastures and human settlements. The damage caused by deforestation, however, can be great. If land is not somewhat reforested it can cause damage to habitats for wildlife and other plant life, affect the aridity of the region, and possibly encourage degradation into wasteland. Due to negligent...
