EROSION AND PREVENTION

Humans live and develop from generation to generation, the more human life is growing the more food needs that must be fulfilled by the man himself. Human development and soil conditions to produce these foodstuffs are in an unbalanced state, which means that the soil factor remains a human factor will always increase. The unbalanced state is more unbalanced by the actions and actions of man himself.

Nowadays many productive lands are threatened with extinction, because of the negligence of humans, the dangers of erosion that have recently occurred in our country have reduced the productivity of the land. The erosion hazard that affects agricultural lands and the population often occurs on lands with slopes of more than 15%.

This danger arises in addition to human acts that are too concerned with the satisfaction of self-need, also due to improper management of land and irrigation. Erosion can also be called erosion or sliding, and is a process of sweeping the soil by the forces of water or wind, whether naturally occurring or as a result of human actions.

Erosion can naturally be said to cause no great calamity for human life or environmental balance and possibly even small losses, this is because the number of soil particles displaced or transported is balanced by the amount of soil formed in the lower places.

In order to prevent and / or control erosion, it should be noted that several factors that influence erosion are: Climate, Soil, Topography, Vegetation of cover and human activities, then we can determine that this erosion control effort should be based on principles: Soil surface so that the surface layer of the soil is resistant to the impact of the collision of rainwater grains, Increases the soil infiltration capacity, so that the flow rate of the surface can be reduced, Reduced the rate of surface water streams so that the scraping of the soil can be minimized, Soil damage and surface drifting power on soil particles can be minimized.

Given the above principles, erosion control efforts can be carried out with technology: vegetative or biological methods, mechanical means, and, Chemical way by utilizing soil feedstocks.

There are ways that are preventive and some are repressive, and some have to be carried out by the farmers or users of the land itself. And if the soil damage has been severe, it must be handled by the government with the participation of the farmers themselves. The preventive course of course if the eroded soil conditions are not so severe, preventive means prevention.

This precaution will involve the government who will conduct counseling and guidance to the farmers, about the good tillage of the land. The repressive, the actions that need to be done by the government, given the severity of soil damage that occurred. For example, barren hills, critical soils in the watershed, siltation of the river and so on.

The government’s efforts in this regard are to provide such a large selection of seeds for reforestation and afforestation, a number of costs for the construction of permanent dikes and other costs associated with labor-intensive projects involving labor in the countryside The framework of flood prevention seems to be for such as erosion prevention that you can see through https://www.maccaferri.com/us/products/geomats-macmat/macmat/. All preventive and repressive efforts should be accompanied by decisive action against those who destroy the forests, soil and water.
