There are problems Nigerians are facing when it comes to soil degradation. The country is striving to come out from this problem, but the lack of education at an increase mong its working class and farmers have not allowed it to fight a good fight against soil degradation. Today, many lands are no longer useful for agriculture or pastoral activities. This also affects the revenue the government generates from exportation of cash crops and animals. This growing soil degradation also affects industrialised farmers. This is causing many Nigerians to go out business or loss their job. On a general term, here is some the effects of soil degradation in Nigeria.
Drought and Aridity
The southern Nigeria is not really facing this problem because of the increasing and irregular rainfall in the region. However, the Northern part is facing aridity and drought, which are highly influenced and amplified by soil degradation. A study by three professors from three different federal universities in the country and a UN arid zone researcher, titled “Trends in Aridity of the Arid and Semi-Arid Regions of Northern”, claims that aridity stretches from Kebbi through Niger, to Bauchi, Kaduna, Gombe and Borno up north, covering states like Yobe, Jigawa, Kano, Katsina, Zamfara and Sokoto states. Northern part of Adamawa state experiences drought stretches about 240,000K^2(Sawa, Ati, Jaiyeoba, Oladipo). Figure 4 shows the area in the North where doughty land is found to be a threat.
As mentioned earlier, some southern states are facing floods and erosion has taken over some the regions. Soil degradation affects the physical composition of the land thereby altering its natural landscape. However...

...opriate measure for making zero deforestation, soil’s ability to naturally regenerate can be restored (Kukreja).
Many farmers in Nigeria does this. Many towns in the country have been doing this practice for ages. However, since Nigerians look up to the government a lot, the government should make sure proper tillage mechanisms are carried out since it has proven to be a sustainable way of avoiding soil degradation or quality decline.
Soil salinization is never helpful in reducing soil degradation. However, preventing it will be a very good idea because it is environmentally friendly to do, and soil salinization detrimentally effect plant growths and yields, and causes soil erosion when the amount of salts in the soil strongly affect the crops. Therefore, I assert that Nigerian citizens needs to prevent soil salinization.

- One of the most compelling problems we face today is the degradation of the Environment. Though nature does contribute to the degradation of the environment through natural disasters and wildfires, the most apparent and controllable contribution of harmful acts to the environment are humans. Some factors that cause this degradation are overpopulation, pollution, deforestation, human interference, and government corruption, landfills and land disturbance. These then go on to affect loss of biodiversity, impact on human health, ozone layer depletion and of course loss of tourism industry.... [tags: Natural environment, Environmentalism]

- Brief Introduction According to the World Ecology Report of Spring 2009, dry lands comprise of 41% of the earth’s total land area, and are home to roughly 2 billion people, or 34% of the earth’s population. It claims that currently (2009) over 250 million people in more than 100 countries were directly affected by desertification and more are at risk (This number would have increased already). The situation is more severe in Africa, where 66% of the total land area are arid or semi-arid. Not only is desertification harmful to the earth and its inhabitants, but it is also expensive each year, the world loses US$42 billion to desertification and its effects” (World Ecology Report, Spring 2009...

- What is deforestation, degradation and climate change Deforestation: It implies the long term permanent loss of forest cover and implies transformation into another land use. Such a loss can only be caused and maintained by a continued human-induced or natural perturbation (FAO, 2001). Forest degradation: The long term reduction of the overall potential supply of benefits from the forest, which includes carbon, wood, biodiversity and other goods and services (FAO, 2003). Climate change: It refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer)....

From that point we can infer that soil is linked to everything around us and plays many significant roles in sustaining life on earth. Soil is defined as the surface of the earth’s crust. Soil degradation is defined by Environment and Heritage, a conservation body as the decline in soil quality caused by its improper use, usually for agricultural, pastural, industrial or urban purposes....

In all cases, the impacts of human activity are indelibly linked to desertification. In 1977, the United Nations Conference on Desertification proposed a definition: "Desertification is the diminution or destruction of the biological potential of the land, and can lead ultimately to desert-like conditions....
