Could Salty Soil Suck Water Out Of The Martian Atmosphere?
2012-02-29 03:51:57

The frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain. A new study, led by an Oregon State University geologist, has found that that the salty soils in the region actually suck moisture out of the atmosphere, raising the possibility that such a process could take place on Mars or on other planets. The study, which was supported by the...

The contamination caused by road traffic not only affects the air, it also seeps under the asphalt and harms the adjacent soil and plants. José Antonio Carrero, a chemist at the University of the Basque Country (UPV/EHU), has delved into the subject and studied the extent of the impact of the metals emitted by cars. Likewise, he has analysed their consequences in the short, medium and long term and for this purpose has taken samples from roadsides in Bizkaia (Basque Country) of...

Humans May Have Played Role In Loss of African Rainforests
2012-02-12 06:25:20

An influx of humans into the lush rainforests of Central Africa, and the deforestation that followed, may have played a role in changing the landscape of the region into the savannas and grasslands that exist there today, a team of French scientists claim in a new study. According to Rachel Nuwer of Science Now, lead author Germain Bayon, a geochemist at the French Research Institute for Exploration of the Sea in Plouzané, and colleagues originally intended to study the...

The effects of climate change could expose Australians to greater risks from toxic contamination, a leading scientist has warned. Increased flooding could release contaminants previously regarded as secure into groundwater, rivers, oceans, the food supply and atmosphere, the director of the CRC for Contamination Assessment and Remediation of the Environment, Professor Ravi Naidu said today. “Most of our urban landfills contain highly toxic substances from past decades — and...

When the water in the Mississippi River rose to 58 feet with a forecast of 60 feet or higher in May 2011, the emergency plan to naturally or intentionally breach the levees, established over 80 years prior, was put in motion. The flood of 1937 did top the frontline levee and water passed into and through the New Madrid Floodway, but being floodfree since then caused area landowners to oppose the plan being put into action. "After a delay due to a legal appeal from area landowners, the U.S....

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...

Sheet Mulching
2013-08-05 12:36:35

Sheet mulching, or lasagna gardening, is the process of turning barren ground into a more nourishing garden without digging. It is a layered system that can be used for a yard garden or a topical box garden. Starting at the bottom is a weed proof barrier, like newspaper or cardboard. On top of that is a twelve-inch layer of compost or mulch material such as old clothes, yard clippings, and manure, which provides for nutrient rich soil. Weed-free soil is added prior to planting the desired...

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...

Land Degradation
2013-04-02 09:20:15

Land degradation is a process in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting on the land. It is also the gradual destruction or reduction of the quality and quantity of human activities, animal activities or natural means. It is viewed as any change or disturbance to the land perceived to be deleterious or unwanted. Natural hazards are not included in the causes; however, human activities can indirectly affect...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...
