| Video Discription | This topic video introduces the process of desertification, explaining what it is, where it is more likely to occur. It also discusses the different human and physical causes, including population growth, climate change, deforestation and poor farming techniques. This topic is part of the AQA GCSE Geography course - Paper 1: Unit 1B - The Living World.

Population growth and migration contribute to increased pressure on food and water resources, while climate change leads to drier conditions and reduced agricultural productivity. Deforestation disrupts the soil's stability and fertility, and poor farming practices, such as overgrazing and over cultivation, further degrade the land. Monoculture and inadequate irrigation systems exacerbate soil infertility and water scarcity issues. These causes highlight the complex interplay between human activities and environmental changes in driving desertification.
