Explanation:
In hilly areas, farming is done by cutting steps on the slopes of the hills. This slows down the flow of water and soil removed from one step is deposited on the next step. Thus, the soil is never completely lost. This is terrace farming.
Answer:
List for preventing soil erosion and land degradation are:-
(a) Cultivation and farming
techniques: Certain cultivation and farming techniques also reduce soil erosion.
(b) Strip Farming: This method is another method of soil erosion. This involves planting
the main crops in widely spaced rows and filling in the spaces with another crop to
ensure complete ground cover. The ground is completely covered so it retards water
flow which thus soaks down into the soil, consequently reducing erosion problems
Terracing is another method of reducing or preventing soil erosion on mountain
slopes. In this method, terraces are created on the steep slopes. Terracing is usually done on slopes, by leveling off areas on the slope to prevent the flow of water down it.
