The issue under discussion is desertification. This is a big problem in some parts of the world, such as Africa, the Middle East, South America and more. This is a problem that mainly arises from climate change, deforestation and drought. The reason why desertification results from these problems is because, for example, when trees are cut down the soil does not have enough nutrients. Another example is when drought occurs, the land becomes very dry and there are no nutrients in the soil, so it becomes desert-like and makes the land unusable for agriculture and other things. Furthermore, the United Nations has taken many actions regarding this topic. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

The UNCCD, the United Nations Committee to Combat Desertification, is a committee that has conventions on desertification, why it is a problem and how we can solve it. The UNCCD created the Committee on Science and Technology (CST) (Tsuei, 3,4,5). This committee examines desertification cases and scientifically created the best solution to the problems. The reason they do this scientifically is because some solutions may not be very good for the environment. The CTS has had a very powerful impact on political actions. There are many committees like the ones listed above that help within the Model United Nations, however not all countries are involved in the committees to help desertification (Tsuei, 3,4,5). An example is Canada. Canada withdrew from the UNCCD and has a major problem with desertification, but this problem is not among its major problems (Tsuei, 3). Furthermore, the economy has a very large impact on this problem. This is because desertification makes land in rural areas unusable, preventing people from having jobs and therefore moving to the urban part of the city. When people living in rural areas move to urban areas to live and find work because their farmland is not fertile and suitable for crops, the city may not always have work for those people. Furthermore, many times there are many problems in urban areas that did not exist in rural areas and many times they are unable to deal with all those economic problems and so those people remain living on the streets without money, making cities or even towns a higher poverty percentage. large and the creation of a not very balanced economy. (Tsuei, 4) Desertification can have a very large impact on the environment or a small impact. The reason it can have a really big impact is because the land on farms may no longer be usable and the food supply they produce would not be able to reproduce because the land has no use.

According to *citation missing* desertification can affect human health because as farmland is desertified, crops cannot grow, and no crop means no food. All this leads to malnutrition because you don't eat enough and your body needs more food but there is no way to give it to your body because there is no food because of this.
