Introduction
In the IB Environmental Systems and Societies (ESS) course, water management is one of the most practical and applied topics. By the 2026 first assessment, students are expected not only to identify different strategies but also to critically evaluate their sustainability.
Water management connects to nearly every other part of the syllabus: food production, population growth, biodiversity, and climate change. That’s why examiners often design questions around how societies manage freshwater resources—because the answers demand systems thinking and a balanced perspective.
Quick Start Checklist for ESS Students
When studying water management strategies, make sure you can:
- Distinguish between large-scale and small-scale methods.
- Give named examples of strategies in action.
- Evaluate advantages and disadvantages of each approach.
- Link water management to sustainability goals.
- Use case studies in exam answers.
Why Water Management Matters in ESS
Freshwater is a finite and unevenly distributed resource. Agriculture, industry, and households all depend on it, but climate change and population growth have made scarcity one of the defining environmental issues of the 21st century.
ESS requires you to understand management strategies on two levels:
- Large-scale (national or international projects).
- Small-scale (community or household solutions).
Both approaches are necessary—and both come with trade-offs.
