The goal of this session is to explore and contrast through case study presentations a cross section of integrated groundwater management approaches in varied policy and legal settings and identify challenges and best management practices at work. Presenters will be a mix of invited and abstract submittals with a broad geopolitical variety from different states and countries, and presenters are asked to cover the legal, policy, institutional, and groundwater management framework; major obstacles and impediments; and what they consider best practices that are working in their area to address specific challenges.
