Desertification Essay

Everyone talks about climate change and how the Earth is slowly deteriorating, but no one seems to have specific examples. In Linnea Saukko’s “How to Poison the Earth,” she does use specific examples of what is causing climate change. She uses satire with a hint of sarcasm in her essay. She gives the reader specific examples of how to poison the Earth, but not really wanting to poison the Earth. Gretel Ehrlich writes her essay, “Chronicles of Ice,” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed, sensory description to explain

In an arid land, there is less precipitation than the potential evaporation which is not the case in humid regions.

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

Environmental scanning can be viewed as a way of acquiring information about outside events that can aid organizations in first identifying potential trends, then interpreting them

The project identifies and analyse how the vegetation of the area can be influenced by soil composition and climate by performing first hand investigation such as analysing soil type and grain size. It’s also about the aspects of the local environment that have been affected by people and propose realistic solutions to the problems that exist.

A food desert can be defined as an urban area where the residents must travel more than one mile to have access to affordable fresh fruits and vegetables (USDA, 2015). Food insecurity is defined as insufficient quantities of food available or on an consistent basis, lack of resources to obtain appropriate foods, and suitable knowledge of basic nutrition, as well as water and sanitation (WHO, 2016) What this means is that if a person has access to nutritious foods for an adequate diet, but lacks the proper knowledge to use those foods in a healthy or nutritious way, then that person has a degree of food insecurity. When a person lacks all three components (access, resources, knowledge), they are said to be severely food insecure.

While reading through the Document Based Question I found out that Desert’s can be identified by their past, present, and future. Desert’s have been around for a long time. “ Did not begin until the 7th century” (Doc 2). This shows that Desert’s have been a thing in society since the 7th century. Desert’s have been around for over millions of years. “ The arid Sahara may have existed at least 7 million years ago.” (Internet). This shows how long Desert’s truly have been around for. To recapitulate, Desert’s can be identified by their past details, present details, and future

A food desert is an area, typically of low income and minority residents, that lacks access to nutritious and affordable food. Food deserts are places where there are not enough supermarkets, thus the population is deprived of whole foods such as fruits and vegetables. On the contrary, an area with many grocery stores and an abundant supply of affordable and healthful food, is known as a food oasis. In 2010 the United States Department of Agriculture reported that roughly 18 million Americans live in food deserts. These food deserts are defined by residents living more than one mile away from a grocery store in urban or suburban areas, and more than 10 miles away in rural areas (Lee, 2017). The food desert areas put those families and and individuals who are already at a disadvantage, and puts them in a position of greater disadvantages. Food deserts are a social problem for they have detrimental effects on society, and exacerbates the instability and inequality within a community.

Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to

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.

Presently droughts occurring every two years and when it does rain only fractions of what the region is used to comes down because a rise in of this food prices, homelessness, diseases, social chaos is in full heat. One in every 3 people you see is dying from malnutrition.Feeding centers and medical supply demands are so high and the respond to get food and water there is not happening fast enough.If poor hygiene continues death will be the result.

Drought is another factor of climate change that causes severe damages to agriculture and livestock. The effects of drought on agricultural production and livestock holding can be a detrimental issue and result in quality dissatisfaction of products. The agricultural industry can be affected by drought both economically and environmentally. The economical effects of drought on crops and animals can lead to the loss of money and time. When droughts occur farmers lose money because they will have to spend more money earned from their

Desertification is defined by the UN as the “persistent degradation of dryland ecosystems by human activities, including unsustainable farming, mining, overgrazing and clear-cutting of land and by climate change” (“Desertification”). Desertification can also be defined as a process that reduces biological productivity and the intensification of desert conditions (Hellden 372). Although less publicized, desertification is an issue that requires international cooperation as the victims of drought, famine and the numerous environmental problems of dry lands are over 250 million, and more than one billion people in over 100 countries are at risk (“Desertification as a global problem” 1). Additionally, desertification tends to affect

The Measurements of Desertification “Drought and desertification threaten the livelihood of over one billion people in more than 110 countries” warned general Kofi in 2001 (Kovach,2003). Desertifications definition is highly disputed but it is generally the shift of arid or semi-arid regions to desert-like conditions, which support: little vegetation, a low soil fertility and high evaporation rates (Haggett, 2001). This work will overlook how deserts are measured by a variety of different means. To measure the growth of deserts characteristics need to be obtained.

Significantly, desertification also cause soil erosion, which means soil surface is worn by wind and water. Desertification makes soil easy to erode by water or wind, as soil is exposed and soil structure is instable without forest. LaI R(2003) says that ““Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected.” To control soil erosion, an obvious way is virescence, enlarging forest cover, which can protect the soil far from exposing to strong wind. Also, the roots of plants under ground play a role as a framework, as they are obstructions to soil movement,
