has been ruled out as the primary cause of methane gas release on Mars, Newcastle University academics have shown.
It is found that a consolidated thin layer with a certain stiffness was formed at shallow depth of sands after treatment, which demonstrated the MICP technique can effectively improved the wind erosion
resistance of sands and suppressed dust.
Highlighting the unprecedented importance of forests in dealing with various climate change induced threats, particularly floods, desertification, wind erosion
, storm-rains and heavy winds, he said forests remained a major workable solution to the negative fall-outs of climate change on Pakistan's socio-economic sectors and lives as well as livelihoods of the people, particularly agriculture and growing air pollution.
"This situation then eliminates many of the solar wind erosion
processes that occur within the planet's ionosphere and upper atmosphere, allowing the Martian atmosphere to grow in pressure and temperature over time," (http://www.hou.usra.edu/meetings/V2050/pdf/8250.pdf) researchers said in a paper on the subject.
The practices loosened the region's drought-ridden dryland, exposing soil to severe wind erosion
. The dust storms that resulted wreaked havoc for more than a decade.
Their formation processes can be roughly divided into three categories: (1) compound blowouts formed by the expansion and joining of simple blowouts during their development (Figure 4(a)); (2) compound blowouts formed by the activation of fixed blowouts that have been superimposed on the original depressions or their edges (Figure 4(b)); and (3) secondary blowouts and parabolic dunes generated by wind erosion
in the sand deposition zone of large-scale blowouts (Figure 4(c)).
More than 80 percent of Uxin Banner is impacted by wind erosion
and desertification, and addressing these challenges calls for a concerted effort.
In the first session, headed by professor Mukhtar Ahmed al Mustafa, a number of papers will be discussed including the question of desertification in the Sudan, the green belts in the Sudan, the biological methods for controlling wind erosion
using shelterbelt, and the role of the Mesquite on desertification control, as well as the Slovakia experience in the areas of green belts.
The remaining area is left undisturbed so that the cover crop residue remains on the surface, providing protection from water and wind erosion
. The researchers used rye as a winter cover crop to protect the soil, increase organic matter, and hold nutrients remaining from previous cropping seasons that otherwise might leach away.
The soil-rated themes discussed in this paper are: soil acidity, wind erosion
, water erosion, soil organic carbon, soil compaction, water repellence, and nutrient status (phosphorus).
The rich soil was capable of producing big crops during wet seasons, but was also subject to severe wind erosion
. Through the years, more land was put into production due to agricultural mechanization.
Others say it could be a fluke formation like those on Earth caused by wind erosion
