Dryland refers to areas of land that receive little to no rainfall, making them arid or semi-arid. These regions often have limited vegetation and are characterized by drought-resistant plants, such as cacti and shrubs. Drylands can be found in various parts of the world, including deserts like the Sahara and grasslands like the Great Plains. Dryland ecosystems play a crucial role in the global environment. They support unique wildlife adapted to harsh conditions and are important for agriculture, particularly in growing drought-tolerant crops. Sustainable management of drylands is essential to prevent desertification and maintain biodiversity.
