The Cause And Effects Of Desertification

There are many horrendous effects that come from population growth. One of the many major effects include decreasing amounts of available land. Another is the decreasing amount of essential natural resources. A part

Now, humans have a steady food supply so they do not have to move about. Therefore, people use fences to keep their animals in one place, which causes overgrazing. Today we see many subjects being affected by desertification. Ute Schaeffer reports the affects of desertification in, Down to Earth: News & Views on Desertification,“(doc.3) It has presented a challenge for governments and aid agencies in over 110 countries for some time, and is a contributing factor in poverty and regional conflicts, for example in Sudan. It has also been a major issue in Egypt, where 90% of the country’s land mass is desert. Faced with a rising population, the government has had to undertake a number of settlement and irrigation projects to create additional living and working space.” Necessary changes were made in order to adapt to the conditions of the desert and the obstacles that have to be faced. It is always presumed that there are only negative aspects to deserts but this isn’t always the case. There is a side to the Sahara desert that acts as a home to several living organisms. The Sahara has vegetation and access to water, which allows life to exist in this region. The Nile Valley, for example, is an area that is still quite full of foliage, trees and other growing things. This area is an exception, because of the way it is fed by the Nile River. Another area of the Sahara that has some vegetation to it is in the North, along the Mediterranean where olive trees grow

The drought was brought on by changing climate in the mid-west; the drought during the Dust

This causes the desertification and it also slows down progress for finding areas that can be medicine for certain diseases. Grasslands act as a big sponge, as they are able to absorb the rain that falls throughout the grassland. Because of this, there's fertile land, and abundance of nutrients for migrating wildlife. In south Africa, companies have put non-native trees in the grassland which is taking away nutrients from the area. In the Florida Everglades, they're only about 80 Florida Panthers left. The big problem that I notice is that we are able to make plenty of land for agriculture but not for people. In only three years, farmers in Zambia have created food security for 16,000 farmers. Glaciers are melting all run the world, however the speed of this has went up three times as much in the last 50

In addition, Darfur’s terrain can be classified into four individual sections: mountains, basement rock, watercourses, and sand. In Darfur a large amount of the arable land consists of goz (soil sediment where vegetation grows). Goz can be useful for farming but primarily offers land for grazing herds. Then, through a process the land around the watercourses and the goz makes the land fertile. Each year the land becomes less arable. Also desertification (process that includes arable land decreasing and the desert area increasing), deforestation, the drought and over use of the land have fueled the conflict between various tribal groups. This has caused most of Darfur’s population to become dependent on the southern region. The lack of fertile land is causing the

Drought can occur for many different reasons. Drought mostly occurs by not receiving rain or snow for a prolonged period of time. This can occur if wind patterns change. Humans can also cause drought by cutting down broad areas of trees resulting in the soil in the ground being unable to hold water, a great example of this is the dust bowl of the

A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems

Right now there is a drought in California and it is due to the water usage. Bach in the gold rush due to miners mining for gold, the rivers became polluted and freshwater became limited. After the earthquake in San Francisco that cause a big fire, San Francisco was in dire need of water so they made a plan to built a dam in Hetch Hetchy. Many people argue as to whether to build the dam and in the end the dam was built and that has shape California’s water system hugely. The use of water in California now has not been in the best interest of the state because The amount of water use for agriculture is disportional, laws are making us use more water than needed and the Indians and environment are being harm.

There are now places where they have become extremely dried than they were before such as south africa. Not only have this places become more dry but they are now receiving half of their rainfall. For the following years in central Africa lake Chad has shrunk and seems to get smaller due to lack of rainfall. The lake depends on its waters for crop irrigation, livestock and specially for water drinking.

Arid environments are hostile for plants and animals to thrive and have very little precipitation. Arid places have very limited water because of exceptionally little precipitation. Egypt can vary from extreme heat during the day to frigid nights. Most of Egypt’s wildlife is nocturnal to escape the heat. Most arid places are nearby the equator.

Along with water availability, another important factor is the soil’s fertility. Because of too much farming on the same piece of land, the soil’s nutrients start deteriorating over the years, and in the end, the soil is literally “mined of life”. Bad application of fertilizers also adds to this. Right now, East Africa is heavily reliant on imported fertilizers, but because of transportation costs and no nearby suppliers, East Africa is paying about 2~6 times the amount of of the world’s

Drought, like a destructing earthquake or flood, is a natural disaster. Drought is an insidious hazard to nature. It results from a deficiency of precipitation over a long period of time over an area. Precipitation is any kind of moisture like rain, snow, and sleet. One can determine how malicious a drought can be by the amount of precipitation, and how long it is (Gleick, 2006).

The scarcity, depletion and polluting of water in one of the world's driest regions, is a problem that has perplexed the nations of the Middle East for decades. The riparian states of the Jordan River Basin include Israel, Jordan, Syria and Lebanon. These states are in a constant struggle over securing water rights for their respective states. The conflict over water is also overshadowed by the Arab-Israeli issues and the subsequent territorial questions. While territory is often at the forefront of the issues, securing water has also become a contributing factor in the conflicts of the past, and will continue in the future. Choices of conflict or cooperation will have to be made, given the diminishing amounts of water available.

There are a variety of causes held responsible for the water crisis in Africa. These causes have been taken from African’s control and desperately need to be solved. Climate change is one of the countless reasons that there is a high demand for water in Africa. An article entitled “Africa’s Water Crisis Deepens” written for the 2006 News Scientist, states that Drought, famine and spreading deserts have plagued Africa for the past 30 years. With the expansion of desertification, the process in which land becomes increasingly dry with little to no water resources, areas of land have dried out and are useless to humans due to the lack of rainfall on the African continent over the past several years.

Desertification is defined by Scott E Spoolman and G. Miller in their book Living in the Environment as “the conversion of rangeland, rain-fed cropland, or irrigated cropland to desert-like land with a drop of agricultural activity of 10% or more”. To put this as simple as possible desertification is turning usable soil into desert. Dissertation is hard to observe but over time
