What are the methods of preventing or reducing soil erosion?

(N/A) The methods to prevent or reduce soil erosion are as follows:
$1$. Afforestation: Planting more trees helps bind the soil particles with roots,preventing them from being washed away.
$2$. Contour Ploughing: Ploughing along the contours of the land helps in reducing the speed of water flow,thereby minimizing soil erosion.
$3$. Terrace Farming: Creating steps on hilly slopes reduces the velocity of water runoff,allowing soil to settle.
$4$. Soil Cover: Keeping the soil covered with vegetation or crop residues protects it from the direct impact of rain and wind.
$5$. Controlled Grazing: Overgrazing by livestock removes the protective plant cover,exposing the soil; therefore,controlled grazing is essential to maintain soil integrity.
