Engineers at Draper Laboratory and MIT are working under contract with NASA to develop a statistical model that can identify areas where landslides are most likely to occur so that preparations can be made to better respond to a crisis. CAMBRIDGE, MA (PRWEB) April 26, 2013 Landslides, which can destroy entire communities and are on the rise due to climate change, are more often caused by rainfall accumulated over long periods than single storms. Engineers at Draper Laboratory and MIT are...

Precision agriculture promises to make farming more efficient and should have an important impact on the serious issue of food security, according to a new study published in Significance, the magazine of the Royal Statistical Society and the American Statistical Association. In an article about the study in the magazine's May issue, University of Reading Professor Margaret A. Oliver, BSc, PhD, assesses how there is potential to manage land more effectively to improve the farming economy and...

Study Finds Deep, Permeable Soils Buffer Impacts Of Agricultural Fertilization On Streams And Rivers In Southern Amazon
2013-04-24 14:36:32

Marine Biological Laboratory The often damaging impacts of intensive agriculture on nearby streams, rivers, and their wildlife has been well documented in temperate zones, such as North America and Europe. Yet a new study in an important tropical zone–the fast-changing southern Amazon, a region marked by widespread replacement of native forest by cattle ranches and more recently croplands–suggests that at least some of those damaging impacts may be buffered by the very deep...

Wildfires Can Burn Hot Without Ruining Soil
2013-04-24 08:52:48

American Geophysical Union When scientists torched an entire 22-acre watershed in Portugal in a recent experiment, their research yielded a counterintuitive result: Large, hot fires do not necessarily beget hot, scorched soil. It´s well known that wildfires can leave surface soil burned and barren, which increases the risk of erosion and hinders a landscape´s ability to recover. But the scientists´ fiery test found that the hotter the fire–and the denser the...

DAVIS, Calif., April 3, 2013 /PRNewswire-USNewswire/ -- As spring temperatures go up, it's an excellent time for farmers, ranchers and gardeners to focus their attention down to the soil below them. A spring check-up of your soil's health gives clues of your ground's ability to feed plants, hold water, capture carbon and more. No fancy equipment required. Just grab a spade or shovel and prepare your senses to dig a little and learn a lot. "It doesn't matter what kind of landowner you are,"...

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...
