IB ESS Topic 4: Case Studies – Water

Master case study analysis through this comprehensive resource for IB Environmental Systems and Societies (ESS) Topic 4, Water. This workbook connects directly to the IB ESS videos on the IB ESSentials YouTube channel and additional resources on the Topic 4 page at MrKremerScience.com.

This resource helps students build strong, evidence-based responses to Topic 4 essay prompts through four detailed case studies spanning water privatization, water rights policy, and aquaculture. Through structured case studies, a debate framework, and a guided evaluation organizer, students develop skills in comparing water management approaches and weighing the sustainability of aquaculture systems. Designed for both Standard Level (SL) and Higher Level (HL) students, this resource provides a clear pathway to understanding how water issues play out in practice across contrasting economies and ecosystems.

Whether used in the classroom, for homework, revision, independent study, or exam preparation, this case studies resource encourages active learning and helps students develop the analytical and evaluation skills required for success in IB ESS.

Why Students Love This Resource

Unlike traditional revision notes, this resource teaches students how to argue from evidence like a real ESS examiner expects. By comparing Bolivia and South Africa’s water policies, then Norway and Thailand’s aquaculture industries, learners see how the same environmental issue plays out differently depending on a country’s wealth, geography, and values. Students build confidence while developing the skills to analyze, compare, and evaluate water management and food production strategies using named, real-world examples.

Students can use this resource for individual research projects, group debates, or focused revision before assessments.
