Semi-arid rangelands are ecosystems characterized by low rainfall and limited vegetative cover, making them susceptible to degradation and desertification. Research in this area focuses on understanding the ecological processes and dynamics of these environments, as well as developing sustainable management practices to support both livestock production and biodiversity conservation. Key research topics include range ecology, climate change impacts, soil erosion, water management, and the interactions between grazing animals and vegetation. Overall, studies in semi-arid rangelands aim to improve resource management strategies and promote the resilience of these important ecosystems.
