2. Use terracing in farming, as the long slope is shorted into smaller groups of shot flatter slopes, reducing soil erosion
3. Planting cover crops, which are crops that grow horizontally, which form essentially a large cover over the soil, which prevents wind from blowing soil away
4. Strategically placed rocks or boulders can change the way water flows, which reduces the amount of soil erosion as it diverts the water to another direction.
