Multi-scalar drought research is a field that focuses on understanding and analyzing drought conditions at various scales, from local to regional and global levels. Researchers in this area aim to study the interactions between different factors that contribute to drought, such as climate, land use, and water management practices. By examining drought conditions at multiple scales, researchers can better predict and mitigate the impacts of drought on ecosystems, agriculture, and water resources. This research area is important for developing effective drought monitoring and early warning systems, as well as informing drought management strategies and policies.
