A semi-arid climate is characterized by low rainfall, typically between 10 to 20 inches (25 to 50 cm) annually. This climate often features hot summers and mild winters, making it suitable for specific types of vegetation, such as grasslands and scrublands. The limited moisture leads to distinct wet and dry seasons, influencing the types of crops that can be grown. Regions with a semi-arid climate can be found in various parts of the world, including areas of Africa, Australia, and the United States. These regions often face challenges like water scarcity and soil degradation, which can impact agriculture and local ecosystems.
