Soil erosion affects the global community’s livelihoods through a variety of conditions. Some can be air pollution, water pollution, degraded land, and loss of fertile land. What is a solution to this major environmental issue ? Plants. Plants are able to reduce soil erosion by breaking the wind that is able to blow dried up topsoil off to
Soil pollutants have an adverse effect on the physical, chemical and biological properties of the soil and reduce its productivity. Pesticides, fertilizers, organic manure, chemicals, radioactive wastes, discarded food, clothes, leather goods, plastics, paper, bottles, tins-cans and carcasses- all contribute towards causing soil pollution. Metals like iron are present in industrial wastes and reach the soil either directly with water or indirectly through air. (Example, through acid rain). The improper and continuous use of herbicides, pesticides and fungicides to protect the crops from pests, fungi etc.
INTRODUCTION What objects can prevent soil erosion the best? Erosion is the process in which the Earth’s surface gets worn down by the forces of nature, which can be a good or a bad thing. A beneficial result of erosion is the movement of nutrient rich soil to new areas. New plants and trees can grow in those areas, aiding people as well as animals. Erosion can form riverbanks, caves, wetlands, and other habitats for animals to live in.
These are wind erosion, water erosion, chemical degradation, and physical degradation. Of the four, the most dominant ones are wind and water erosion because the are the ones that occur most frequently. Soil erosion is caused by water and wind. Both of these degrade soils because it impacts soil quality. This results in loss of nutrient-rich and fertile top layers and reduced water retention.
Landslide and avalanche are forms of natural disasters that occurs due to natural processes of the Earth such as movement of rock or snow down a slope. The movement of rock, debris or earth down a slope is called a landslide. Landslide usually occurs when the materials which make up the hill slope fail to hold on or due to the force of gravity. Landslides can also be referred to as slope failure, landslip or slumps. The most common types of landslides that occur are earth slides, rock falls and debris flow landslide.
The disasters being described are forest fires, soil erosion, flooding, etc (ERDB 2011). Flood is the cause of overflowing in a certain body of water that covers a dry land . This is the most frequent event brought by typhoons and continuous precipitation and this happens when the water exceeds the absorptive capacity of the soil and carrying capacity of the streams. Also, this can be more hazardous if the event happened in a flood prone area. Many provinces and municipalities in the Philippines are exposed to this type of event like Sta.
Plants retain the minerals from the dirt so as to survive. At the point when these minerals are spent, the plants will start to shrink. Without water getting into the dirt, the ground will dry out and get to be unstable. Increase in breaking up of particles and loss of topsoil can be extreme if a high-power rainfalls on ground that is poor with regards to a ground front of
Microbiology communities in the soil can also help to break the rocks apart by burrowing and digging through the ground. Another factor is roots and plants when they push into the rocks and break them apart. There are two main types of physical weathering: Freeze-thaw which occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. And exfoliation which is occurs as cracks develop
Flood causes some amount of topsoil to lose. Topsoil is the part of soil wherein higher amount of nutrients and organic matter were found thus the removal of it always has a great impact on the productivity of agriculture. Most evident effects of floods are those that are caused by man's activity such as deforestation and urbanization. These activities expose the soil and change the properties of water (Khalekuzzman, 2004). Nowadays, There are a lot of ways to address floods.
After mining operations, the change in topography and stripping of vegetation can lead to soil erosion, not only washing precious nutrients away and clogging up waterways with run-off, but also creating unsightly and unusable heaps of dirt. This is why rehabilitation of mining sites is so important, it is important to establish new growth as quickly as possible and allow any land destroyed by mining to be put to better use for forestry or grazing purposes. Coffey says,"It is possible and important to rehabilitate any degraded land, which generally includes mining, where you end up with large amounts of overburden as the final soil profile. "Rehabilitation sites helprestores the vegetation that was lost during the mining activities.The most common
