Dryland ecosystems refer to arid or semi-arid regions characterized by limited availability of water and low levels of precipitation. These ecosystems are home to a diverse array of flora and fauna that have adapted to survive in harsh, arid conditions. Research in dryland ecosystems focuses on understanding the unique ecological processes that govern the functioning of these ecosystems, as well as the impacts of climate change, land degradation, and human activities on their biodiversity and resilience. Key research topics in this area include drought adaptation, desertification, desert flora and fauna, water management, and sustainable land use practices. Studying dryland ecosystems is essential for developing strategies to conserve and manage these fragile environments in the face of growing environmental challenges.
