Desertification is a global environmental problem that the textbook Principles of Environmental Science: Inquiry and Applications,written by William P. Cunningham and Mary Ann Cunningham, defines as the “process of conversion of once fertile land to desert” (140). This process occurs mainly in areas that are highly cultivated, overgrazed and also in areas where water resources are scarce. The United Nations Convention to Combat Desertification (UNCCD) has determined that this process is most detrimental in “arid, semi-arid and dry sub-humid areas” (United Nations).
The above mentioned areas that the UNCCD has determined are most concerning were “home to a third of the human population in 2000” and “occupy nearly half of the Earth’s land area” (GreenFacts). This means that roughly a third of the population is living in areas with degraded soils lacking nutrients or sufficient water supply. Some of these areas include surrounding parts of the Sahara Desert in Africa has well as much of China. The causes for desertification are the same throughout the world but may be more damaging in these areas. These causes include intensive agriculture, overgrazing of animals and lack of water resources.
In agriculture, “row crops […] leave soil exposed for...

...e should not consider it a local problem. To reiterate, this area has suffered from drought for much of the past decade. Water resources are becoming more scarce and cities and states are fighting over rights to the current water. California is a major producer of agricultural commodities that feed much of the world. If desertification is allowed to go unchecked in this area, we may one day be living in desert conditions.
Overall, desertification is a worldwide problem that needs all of our attention. Numerous cultures in mainly rural areas are being exposed to massive wind storms, deteriorating food quality and quality of life because of this environmental problem. There are a few organizations whose common goal is to stop and reverse desertification. In the end, I hope more people become educated about this topic and actively take steps to end its destruction.

- California’s central valley conjures images of lush, green landscapes; however, it has been plagued by drought for much of the past decade. While we may have only felt most of the effects of drought in our bank accounts with increasing water rates, the central valley has felt the effects in another way – the process of desertification. The process has caused major concern for many in the agricultural community but has moreover led to a widespread concern for much of the developing world. Desertification is a global environmental problem that the textbook Principles of Environmental Science: Inquiry and Applications,written by William P.... [tags: Environment ]

- Imagine a typical farmer tending his cattle and harvesting his crops, a harmless act. His land is green and fertile, and the beautiful view stretches on forever. Now, conceptualize that healthy land morphing into dehydrated sand...a desert. It is nearly impossible for vegetation and humans, such as this farmer, to survive and thrive on land that receives less than three inches of rainfall each year. Unfortunately, this is not a fiction scenario. Deserts are growing at about twenty thousand square miles every year (Roos).... [tags: environment, drought]

- DESERTIFICATION Desertification of the arid lands of the world has been proceeding--sometimes rapidly, sometimes slowly-- for more than a thousand years. It has caused untold misery among those most directly caught in it's path, yet environmental destruction continues. Until recently, few if any lessons seemed to have been learned from the past, in part because the problem went unrecognized in it's early stages or was seen as a local one only affecting a small population, and in part because new lands were always available to start over again....

- The number of environmentally displaced people is growing and it’s important for individuals to be informed of the topic and what all it entails. A study published by Economic & Political Weekly, in 2009, approximates 24 million displaced people due to climate change and environmental situations. (Economic & Political Weekly, 2009) That number was estimated to grow to 50 million by 2010, and exceeding 150 million by 2050. (Economic & Political Weekly, 2009) The world has to be informed of what these numbers mean.... [tags: Environmental Displacement Research Paper]

- ¬¬Earth is currently being populated with over seven billion humans, which just in the last two centuries had increased from one billion in 1835, to two and a half billion by 1950. This figure more than doubled in a mere forty-five years to about six billion (Chiarelli). Now that we have seven billion people populating from all walks of life, this presents us with a dire situation on hand. In fact, overpopulation is the world’s leading problem since it causes a domino effect to many of the predicaments the world is currently facing....

- Do We Have a Population Problem. Amanda Bruette Core III Environment and Consumption 3/11/15 Professor Patrick Parise The world’s population is unarguably on the rise. The real argument is if we should be concerned or see this as a serious problem. With this constant growth, there comes a rising concern for the food supply. Not only that, but other resources are in danger. On the other hand, over population is believed to be a myth. This causes for two very different opinions on this topic. The overall population keeps growing.... [tags: Overpopulation, World population]

- Although previously represented as an achievement crafted primarily by the actions the World Health Organization (WHO) and a small group of other key players, recent interpretations of the eradication of smallpox are dealing with this international cooperation and its players from different angle. Current historians are examining this achievement as one shaped not only by the mutual understanding for the need to end smallpox but also by international and local sociopolitical forces. In his 1993 article, “Smallpox: Emergence, Global Spread and Eradication, “ Frank Fenner, a noted virologist and the Chairman of the Global Commission for Certification of Smallpox Eradication, explains the hist...

- Chinese climatic history is colored with desertification. Desertification is the transformation of arable or habitable land to desert, by means of a change in climate or destructive land use.1 China is covered by deserts, however this becomes problematic during times of drought and aridity as the deserts expand and threaten local populations. The Gobi desert is the most threatening to Beijing, the capital of China. A study of desertification illustrates Beijing and China ’s weather, climate, and society of both the past and the present.... [tags: China Desert Environment Climate Essays Papers]

- The world’s drylands, contrary to popular misconceptions of being barren unproductive land, contain some of the most valuable and vital ecosystems on the planet. These dryland environments have surprising diversity and resiliency, supporting over two billion people, approximately thirty-five percent of the global population (UNEP, 2003). In fact, approximately seventy percent of Africans depend directly on drylands for their daily livelihood (UNEP, 2003). However, these precious and crucial areas are at a crossroad, endangered and threatened by the devastating process of desertification.... [tags: essays research papers fc]
