What are the causes of soil erosion and how can we solve it |
|
Answer» The following are five important measures taken to prevent soil erosion and ensure soil conservation:Terrace Farming - On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. Terrace farming is practiced with successful results in Japan, South-East Asia and the USA.Shelter Belts - Peasants plant trees in several rows to reduce wind erosion. They are called ‘wind breaks’.Contour Ploughing - Ploughing along contours on a slope prevents soil being washed away by rains or by surface run off. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Contour ploughing is common in countries like Japan, China and some of the South-East Asian countries.Strip Cropping - In this system, crops are grown in alternate strips of land in order to check the effect of the winds.Construction of Dams - Rivers are known to cause soil erosion. Dams are built in the upper course of the rivers in order to control the erosion of soil.\xa0 Causes of soil erosion are over irrigation,over utilisation,over mining etc we can solve it by reducing Causes: 1.large scale deforestation 2.floods due to which the fertile top soil removes out from the fields3.pollution4. Over irrigation in the fields5. High speed windThese can be prevented by planting trees, preventing floods, reducing pollution THE CAUSES OF SOIL EROSION ARE :-1) WIND EROSION 2) WATER EROTION3) HUMAN CAUSES : AFFORESTATION, CONSTRUCTING DAMS E.T.C Check in this app for more information. |
