Which factor is not a cause of desertification?

Desertification is the process by which fertile land becomes increasingly arid, leading to the loss of vegetation and biodiversity, often exacerbated by various environmental and human factors. Sustainable agricultural practices are designed to maintain and enhance the health of the land. They focus on methods that preserve soil structure, reduce erosion, optimize water usage, and enhance ecosystem functions. By utilizing techniques such as crop rotation, organic farming, and reduced chemical inputs, these practices aim to bolster the resilience of ecosystems against degradation, thereby countering desertification rather than contributing to it.

In contrast, factors like climate change, human economic activities, and urbanization can lead to oversaturation of resources, degradation of soil quality, and depletion of vegetation, all of which can accelerate the desertification process. Therefore, while the former three can be detrimental to land health, sustainable agricultural practices work to protect and restore ecosystems, making them a key strategy in combating desertification.
