Desertification Lake Chad in a 2001 satellite image, with the actual lake in blue. The lake has shrunk by 94% since the 1960s. Desertification is a type of land degradation in which relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities.

Chapter 9 South Asia A desert is defined simply by the amount of rainfall that falls in an area in conjunction with the amount of evaporation. In essence, its any area that receives on average less than 10 inches of rainfall per year, and where the yearly evaporation is more than 10 inches of rain a year.

- Desertification This is the process that sees productive land turned into non-productive desert. It usually affects dry areas on the edge of deserts, eg The Sahel, south of the Sahara Desert in Africa.

Desert A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life.The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid.n English before the 20th century, desert was often used in the sense of unpopulated area, without specific reference to aridity; but today the word is most often used in its climate-science sense (an area of low precipitation).

As the moisture in the air goes up and over these ranges, it cools, depositing its moisture load on the range. By the time the air comes down, it has very little moisture left ... thus causing a desert.

-    The continents all have some type of desert. Due to increased  desertification, every continent can now be said to have a desert.  Antarctica is also … classified as a desert because it receives less  than 250mm of precipitation per year, and deserts can be cold areas  as well as hot.   Europe used to be the only continent without a desert.ue to increased  desertification, every continent can now be said to have a desert.

What is Desertification? What is Desertification? Desertification is defined as a process of land degradation in arid, semi-arid and sub-humid areas due to various factors including climatic variations and human activities. Or, to put it in another way, desertification results in persistent degradation of dryland and fragile ecosystems due to man-made activities and variations in climate.

What is Land Remediation? Solidification is the process of adding chemical reagents that will combine with the toxins in contaminated water and sludge to make solid compounds that can be separated from or filtered out of the water. This way the water is left in the natural ecosystem but the chemicals are removed.

DESERTIFICATION OF ARID LANDS Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected nearly 50 percent of the land areas as the result of human mismanagement of cultivated and range lands. monoculture of grain in the cultivated regions has depleted the native fertility of the soil and has been responsible for increasing the susceptibility of the land to wind and water erosion. Extended droughts from time to time have served to accelerate desertification.

World Deserts Map A desert is a region that obtains incredibly less amount of precipitation or it can be also defined as an area where more water is lost by evaporation than water received by precipitation. Most deserts receive an average precipitation of less than 400 mm annually.

About one third of the land surface of the world is arid or semi-arid. desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain but may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.

About one third of the land surface of the world is arid or semi-arid.eserts take up about one third of the Earth's land surface. Bottomlands may be salt-covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as cold deserts) have similar features, except the main form of precipitation is snow rather than rain.

- China. The present average annual rate of desertification/land degradation for the country is of the order of 0.6%, while in such places as Boakong County, north of Beijing in Hebei Province, it rises to 1.3%, and to 1.6% in Fenging County.

What is a Watt Hour? So, here’s a brief explanation of what it is. A Watt Hour is a unit of measurement for power over a period of time (an hour), or in our case, a way of measuring capacity. One Watt hour is equal to one Watt of average power flow over an hour. One Watt over four hours would be four Watt Hours of power. As an example, a 100 Watt light bulb on a 400 Watt Hour battery (like the Yeti 400) would last, on paper, 4 hours.

Soil Nomads are trying to escape the desert, but because of their land-use practices, they are bringing the desert with them. It is a misconception that droughts cause desertification. Droughts are common in arid and semiarid lands.

Effects of global warming on human health Definition.  1 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. 2  In different areas of the world, the causes and effects of desertification may be different. For example, this short report by the BBC in the 1999 shows how different causes of desertification have combined together in China.

Gasification Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.

Desert Survivor I've been writing about deserts for awhile, but it seems that it might be a good idea to define what a desert is.The most basic definition is that a desert is an area that is moisture deficient; more water evaporates than is received.ne of the characteristics of deserts is that they have large temperature fluctuations due to the lack of humidity. Daytime and nighttime temperatures may vary by over 50 degrees Fahrenheit (10 deg C). (Keep that in mind if you're packing for a trip to the desert!). Deserts are not necessarily hot.
