The issue discussed is desertification. This is a very significant problem in some parts of the world, for example Africa, the Middle East, South America and elsewhere. This is a problem mainly caused by climate change, deforestation and droughts. The reason desertification comes from these problems is because, for example, when you cut down trees, the soil doesn't have enough nutrients. Another example is when droughts occur, the land gets really dry and there are no more nutrients in the soil, so it becomes desert and makes the land unusable for agriculture and other things.

The UNCCD, United Nations Committee against Desertification, is a committee that has conventions on desertification, why it is a problem and how we can solve this problem. The UNCCD created the Committee on Science and Technology (CST) (Tsuei, 3,4,5). This committee examines cases of desertification and scientifically created the best solution to the problems. The reason they do it 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 those listed above that assist within the Model United Nations, but not all countries are involved in desertification assistance committees (Tsuei, 3,4,5). An example is Canada. Canada withdrew from the UNCCD and Canada has a big problem with desertification, but this problem is not one of its main problems (Tsuei, 3). Additionally, the economy has a very significant impact on this issue. Indeed, desertification makes rural land useless, which deprives people of jobs and pushes them to settle in the urban part of the city. When people from rural areas move to urban areas to live and find work because their farmland is not fertile and not suitable for their crops, the city does not always have jobs for these people. Additionally, urban areas often have many problems that did not exist in rural areas and often cannot solve all of these economic problems. So these people continue to live on the streets without money, which makes the city or even the country. the percentage of poverty is higher and creates an unbalanced economy. (Tsuei, 4) Desertification can have a very large or minimal impact on the environment. The reason this can have a very big impact is that the land on farms might no longer be usable and the food supplies they produce would not be able to reproduce because the land has no use.
