Why step farming is common in hills?
Answer:
Step farming is common in hills because of its benefits. The major benefit, of course, is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible. Due to the reduction in soil erosion and having high water holding capacity, terrace farming improves soil fertility and land productivity. It enhances biodiversity and helps in ecosystem restoration and enhances biodiversity.
