Deserts are expanding across large parts of the world due to various human and environmental factors. Overgrazing of livestock and deforestation have degraded soils, reducing their ability to retain water. Climate change has exacerbated droughts in many regions, reducing rainfall and causing desertification. As deserts expand, they threaten the livelihoods of those living in increasingly arid lands and could contribute to conflicts if populations are forced to migrate. Understanding and addressing the root causes, such as sustainable land management practices and reducing greenhouse gas emissions, is essential to slow the spread of deserts.
