A semi-arid climate is characterized by low annual precipitation levels, typically between 250-500mm per year. This type of climate is found in regions that receive more precipitation than arid climates but less than humid climates. Semi-arid climates are often associated with areas of low vegetation cover, such as grasslands and shrublands, and are vulnerable to droughts and desertification. Research in this area focuses on understanding the complex interactions between climate, vegetation, and water availability, as well as developing strategies for sustainable land management and water resource management in semi-arid regions. Key research topics may include drought monitoring and prediction, the impact of climate change on semi-arid ecosystems, and sustainable agricultural practices in these challenging environments.
