Aspect 3: The effect desertification has on soils. Desertification is defined as the spread of desert conditions into areas which have not previously experienced such conditions. An example of this is the expansion of the Sahel desert, which moves south at an approximate speed of 10 kilometres per
Soil degradation is an important factor in the environment. It has a negative impact on the soil and land. For this reason it is important to monitor the effects it makes for future prevention. According to The Office of Environment & Heritage, soil degradation “ is the decline in soil quality caused by its improper use, usually for agricultural, pastural, industrial or urban purposes.” Soil can be highly rich in nutrients it is important to be able to improve the quality because it is beneficial for healthy food consumption. It is also important to monitor closely the effects because they can be costly.
Soil is also being affected by Agriculture and affecting family farms leading to high suicides and contaminated soils. Farmers are trying to grow crops in areas that aren’t usually suitable for growing, and applying toxic pesticides and fertilizer to help the crops grow. Farmers are going out of business due to lack of money, getting sick from the toxic stuff companies are giving farmers. Now we are seeing more industrial farming and causing more harm for us and the
This can effect crop production which is essential due to the growing population of the world. Over population often puts pressure on a country to produce more. This leads to poor farming practices, overgrazing and monoculture. The constant land degradation and low rainfall causes desertification in arid and semi-arid areas. The desertification results in unproductive farmland which increases the pressure to produce food even more.
E. Water Erosion: The last type of erosion is water erosion. Water erosion is when the soil particles are moved by the kinetic energy of the precipitating rain. This rain forces the soil mechanically to runoff. There are several types of water erosion: sheet erosion, rill erosion, gully erosion, and bank erosion. a.
However, they suffer from being heavily leached, meaning that many nutrients and minerals are lost from the subsoil. As this leaching has being ongoing for millions of years, the soils are deprived of many nutrients which are required by the flora above the surface. Tropical soils tend to have an extremely thin top layer. This layer is usually composed of decay from the foliage and animal remains. The plants in the rainforest provide fallen leaves and branches to the forest floor which are consumed and broken down by soil organisms and are converted back into nutrients which are consumed by the flora.
This fertilizer has a more long term effect, the fertilizer improves the structure of the soil which makes it easier to hold water and the nutrients it needs to be a long lasting plant(A comparison between). There are not any toxic chemicals that can kill your plant and you can never add too much fertilizer, because there are no toxic buildups. This natural fertilizer is great for our environment, it is renewable and biodegradable, this means we can always have a large supply of the fertilizer. There are also downfalls to go with the natural
Deforestation leads to soil erosion and an increased frequency of floods and droughts. When trees are removed, there will be lesser tree roots to hold onto the soil and lesser rain will be intercepted by the different forest layers before hitting the ground. As estimated 62 percent
Supporters of deforestation might also argue that soil erosion has no negative effects. Anyhow, soil erosion has negative effects that potentially could impact thousands of people. Since the soil is not anchored to the ground firmly and is susceptible to being moved with little force, it can easily get into waterways clogging hydroelectric structures. If these structures get clogged, they will not function properly therefore leaving the population of people it supplies electric for without any electric. If the soil clogs irrigation systems, it will cause issues for farmers as well.
The wet deposition is snow, sleet, fog and rain that usually have a higher PH acidic value than the normal rainfall. Dry deposition is when gases and dust particles also end up having a higher acidic value. Both dry & wet deposition can be carried for long distances by wind as sulfur dioxide and nitric acid easily mix with other substance and they are light in weight thus wind can carry them for long distances. Formation of this deposition occurs when environmental pollutants containing a higher value of sulfuric dioxide and nitric oxide mix together. Acid rain formation is affected by both natural and man-made sources as well as burning of fossil fuel that emits both sulfur dioxide and nitrogen oxides.
