STEENBERGEN, The Netherlands, May 21, 2014 /PRNewswire/ -- A new Groasis invention, a biodegradable version of the proven successful Waterboxx, is the answer against desertification. The Groasis Greenboxx, made of recycled paper, is an environmentally friendly development of the Waterboxx. The Groasis Greenboxx can be used to plant one tree in a desert without using irrigation. It saves up to 97% of water while planting. After a year the Groasis Greenboxx degrades and...

New Tree-planting Technique For Ecological Control Of Desert
2014-04-03 15:52:50

Science China Press When planting seedlings of desert plants in the desert area under no irrigation condition, why is the survival rate so low and the growth is so poor? A recent research using desert plant Haloxylon ammodendron discovered that high desert surface temperature (≥50oC) is a major limiting factor under numerous desert habitats. It provides a novel idea for ecological control measures of desert. Professor MA Hao and his group from Nanjing Agricultural University and Xinjiang...

Overgrazing Is Turning Parts Of Mongolian Steppe Into Desert
2013-09-06 13:27:48

Oregon State University Overgrazing by millions of sheep and goats is the primary cause of degraded land in the Mongolian Steppe, one of the largest remaining grassland ecosystems in the world, Oregon State University researchers say in a new report. Using a new satellite-based vegetation monitoring system, researchers found that about 12 percent of the biomass has disappeared in this country that’s more than twice the size of Texas, and 70 percent of the grassland ecosystem is now...

Climate Change May Have Positive Impact On Some Desert Plants
2012-10-10 09:15:25

Some plants in arid regions benefit from climate change 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 impact on some plants. A study involving the Max Planck Institute for Demographic Research in Rostock has come to this conclusion. Using demographic methods, ecologist Roberto Salguero-Gómez investigates desert plants to...

Study suggests that plant biodiversity buffers negative climate change effects and drylands desertification An international team of researchers including Dr. Bertrand Boeken of the Jacob Blaustein Institutes for Desert Research at Ben-Gurion University of the Negev suggest in a new study that plant biodiversity preservation is crucial to buffer negative effects of climate change and desertification in drylands. The study titled, "Plant species richness and ecosystem multi-functionality...

This Envisat image shows part of central Morocco from the Atlantic Ocean to the west, over the Atlas mountains and into arid parts of Algeria further inland. The snow-capped High Atlas mountain range divides Morocco from the Sahara desert´s climatic influences in Algeria. Northwest of the mountains, the area experiences a more Mediterranean-like climate, with dry and hot summers and moderate winters with a fair amount of rain. Several peaks in the mountain range exceed 4000 m and...

Diverse Ecosystems Are Crucial Climate Change Buffer
2012-01-13 04:37:10

Preserving diverse plant life will help buffer the negative effects of climate change and desertification in drylands Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in the world's drylands, according to a new landmark study. The findings of the multi-author study, published January 12 in the journal Science, are based on samples of ecosystems in every continent except Antarctica. They confirm for the first time that...

Image 1 - Satellites Combat Degrading Lands
2011-10-21 07:48:48

As the UN marked World Food Day earlier this week, international representatives convened in Korea to discuss ways to curb the loss of productive land to desertification. Satellites play an important role in the monitoring and assessment of drylands.   Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations because dryland ecosystems are extremely vulnerable to over-exploitation,...

Desertification
2013-04-02 09:46:56

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
2009-05-27 18:12:50

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...
