Desertification, drought, and leaching contribute to soil degradation and non-arable land.
Desertification is the expansion of dry lands due to poor agricultural practices, improper soil management, erosion, and climate change. Population growth and unsustainable agricultural practices contribute to desertification by degrading soil quality, reducing vegetation, and increasing aridity.
Drought exacerbates desertification by reducing moisture levels in the soil, leading to decreased fertility and plant growth. Leaching also plays a role in desertification as chemicals and pollutants from water supplies can leach into the soil, causing harm and creating non-arable zones.
