Lesson Plan

• Describe the geological, climatic and human causes of multi‑hazard environments.
• Explain how interactions between hazards amplify impacts on people, infrastructure and ecosystems.
• Apply the risk‑assessment framework to calculate total risk in a multi‑hazard scenario.
• Evaluate integrated management strategies across mitigation, preparedness/response and recovery phases.
• Analyse the 2004 Indian Ocean case study to identify key lessons for multi‑hazard risk reduction.

• Projector and screen
• Whiteboard and markers
• Printed handouts with hazard tables and case‑study summary
• Risk‑assessment worksheets
• World map or GIS printouts showing hazard zones
• Sticky notes for group brainstorming

Begin with a striking image of the 2004 tsunami and ask students what other hazards might follow such an event. Review prior knowledge of single‑hazard impacts and introduce the concept of hazard interaction. Outline today’s success criteria: students will be able to identify causes, assess combined risk and propose integrated management actions.

1. Do‑now (5’) – Quick quiz on single‑hazard definitions (paper or digital).
2. Teacher input (10’) – Present causes of multi‑hazard environments using slides and map examples.
3. Guided activity (15’) – In pairs, fill a risk‑assessment worksheet for a given scenario, calculating total risk.
4. Case‑study analysis (15’) – Small groups examine the 2004 Indian Ocean case, identify interactions and discuss lessons.
5. Management strategies (10’) – Whole‑class brainstorming of mitigation, preparedness and recovery actions; record on board.
6. Check for understanding (5’) – Exit ticket: write one key difference between single‑ and multi‑hazard risk.
7. Homework brief (5’) – Assign research on a local multi‑hazard area and prepare a one‑page risk summary.

Summarise how overlapping hazards increase vulnerability and why integrated management is essential. Collect exit tickets to gauge understanding and remind students of the homework research task. End by highlighting that effective risk reduction relies on linking mitigation, preparedness and recovery.
