Desertification As A Global Problem

At present there are many examples of areas that have made their communities sustainable as a result of the UN millennium goal. These goals stated…One example is Milagro. This is a community in Arizona that has recently become sustainable. It is known for its cohousing community of twenty-eight, energy efficient, passive solar homes.

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 concept of a Food Desert is not new, “British politicians introduced the idea of food deserts in the mid-1990s… suggested a link might exist between distance to a grocery store and the diets of poor people” (Gilligan, 2014). It took many years before the idea of a Food Desert was recognized in the United States of America but it is now estimated that, “About 23.5 million people live in food deserts” ("11 Facts About Food Deserts | DoSomething.org | Volunteer for Social Change," n.d.). The inability to obtain healthy food choices leads to, “people in low-income communities [suffering] more from diet-related diseases like obesity and diabetes” (Truehaft & Karpyn, 5, n.d.). The existence of these Food Deserts is a factor that works to keep those in poverty down and makes progress even harder for them to

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

Land use changes, as described by Lappé, include every change of land in order to produce, or distribute, food. Annually, forests, bogs, swamps, rain forests, and other biomes are Ableman 1 destroyed for agricultural purpose. Destruction of these biomes lead to the release carbon dioxide into the atmosphere which is the most prominent greenhouse gas. The second “connection” in The Climate Crisis at the End of Our Fork is the “agricultural connection.”

There is a word “desertification” which indicates that forest losing its own green color. But the desertification doesn’t only happen on the land, it also happens in the ocean. The ocean desertification is being process on the coral reef zones, it is called coral bleaching. The coral bleaching is caused by the increase of ocean temperature, which makes coral reefs to leave only is white skeleton. The main cause of it is by the climate change, which is related to the pollution done by human. Thus to prevent further destruction or to recover some of it, being uncomfortable in our daily lives are necessary. Because the comfortable lives includes the activities that leads to pollution such as using plastic materials, wasting environments, or much

lush watershed eventually turning into a desert. Not only are rivers drying up, but as are aging

Droughts are a natural occurrence that has been around for millions of years. Droughts are unpredictable; no one can tell when they are going to take place, the severity, or how long they will last. Impacts on of a drought can send shockwaves thought the region. The economy, agriculture, the environment, and the residents of the region are all affected. (Vicente-Serrano, Beguería, & López-Moreno, 2009, p.1696)

(Carson, 2017) The land near the Sahara Desert had a dry climate

Currently in the Unite States, food deserts spread all over the country and are expanding to many more rural areas. There are several attempts in many different research that tries to measure, locate and label food desert but in the end, there has not yet been an official scientific way to measure whether a place is included in a food desert and much more study is needed. However the USDA used the Census and Population data to create a food desert locator, which could be accessed by the general public. According to the food desert locator provided by the United States Department of Agriculture (USDA), it is obvious that west America is much more threatened by food deserts comparing to

While many blame current droughts on climate change, rainfall patterns in areas like California—currently in its fourth consecutive year of drought—have actually varied little from a century ago. But if little is done to curb carbon emissions, what is to come may be far worse. In fact, economic losses associated with climate change, globally, will reach an estimated $3 billion by the end of 2015. Furthermore, these human-induced droughts will uproot entire communities and force them to migrate to regions with more water and food. With climate change set to worsen over the course of this century, food and water shortages will only get worse, and not just for Californians.

Finally, based on the Mr. Savory present on how to we fight the desertification and reverse climate change. He was focused on the global rangeland, about two third of the land had become desertification, he thinks that grazing animals should be management of the grassland, so the land would not get destroyed badly. He also mentions the seasonal grassland, if the grass dying out, it will be oxidation and release the carbon. We use fire to burn the grass in order to grow the grass in next season. But this is harmful, he thinks we can put the animals in the grassland, the way can prevent the fire and protect with the soil. Which is a good idea for that. When Mr. Savory came to the United Stated and saw the national park was becoming a desert,

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 a term few people recognize and even fewer are concerned about. This paper will cover what desertification is along with why it is a global crisis, what the root causes of desertification are, what can be done to reverse the harm full desertification process, it will also cover how farmers can work together to prevent future desertification.

MEditerranean Desertification And Land USe (MEDALUS) project is one of the largest project of the European Comission established to analyse the global and regional climate changes. The MEDALUS model (Kosmas et al.1999) identifies regions that are environmentally sensitive area (ESAs). In this model, different types of ESAs to desertification can be analysed in terms of various parameters such as landforms, soil, geology, vegetation, climate, and human actions. Each of these parameters is grouped into various uniform classes and a weighting factor is assigned to each class. Then four layers are evaluated: soil quality, climate quality, vegetation quality, and management quality. As outlined by Kosmas et al. (1999) and Brandt et al. (2003), the method should be reasonably simple, robust and widely applicable; the selection of parameters to assess environmental quality must be made attending to their availability, economy and ability to update and the system should be adaptable to the development and refinement of the existing information content and the possible addition of new information. The principal innovation which was brought in to the study by Kirkby et al. (1998) in their study of MEDALUS was long term interactions with the vegetation and soil, with implications for the way in which the surface flow and infiltration are described and distributed area wise. The model contains four inter-related sub-models for the atmosphere, vegetation, soil and
