Water Scarcity | Complete Geography Lesson | Slides & Workbook

I teach IGCSE Geography at an international school in Southeast Asia. Water Scarcity was one of my best-selling lessons, but the story has moved fast: Cape Town’s close call has been joined by Mexico City and Tehran, and some of the old figures had drifted a long way from today’s data (the UK’s water-use split has literally reversed). So I rebuilt it from scratch, with every statistic re-verified against the latest WHO/UNICEF and UN water reports. If you bought the original, the update is free, just re-download.

What’s in it:
A complete, ready-to-teach lesson answering one big question: if most of the planet is covered in water, why do billions go thirsty? You get a full PowerPoint presentation with answers included throughout (a shade-the-graphs opener on where Earth’s water is, a sources-of-water match, “water diet” pie charts, the physical-versus-economic scarcity distinction with maps and distribution writing, the five causes of increasing scarcity, three close calls from the news, the Singapore Four National Taps and Konso, Ethiopia case studies, a five-minute annotate challenge, a HIC or LIC strategy sort, and a tomorrow’s headline exit ticket), a Word workbook in three versions (Full colour, printer-friendly black and white, ready-to-print PDF), and a 30-question Blooket quiz file for instant retrieval practice. Bonus access to free lesson-support activities and daily games on the Geography Oasis website.

What students learn:

• Where Earth’s water is found and why so little is usable
• The main sources of fresh water, from aquifers to reservoirs
• How countries at different development levels use water differently
• Physical versus economic water scarcity, and their global distributions
• Five reasons water scarcity is getting worse
• How a high-income and a low-income country secure their water supplies

Every figure is re-verified for 2026: about 2.1 billion people (1 in 4) lack safely managed drinking water, and around 4 billion face severe scarcity at least one month a year (WHO/UNICEF 2025; UN 2024). Also suitable for AP Human Geography, World Geography, and any water resources, development or global issues unit at ages 11-16.

Format:
Delivered as fully editable PowerPoint (.pptx) and Word (.docx) files, plus PDF. Diagrams and visuals are not editable.

TEACHING CAMBRIDGE IGCSE GEOGRAPHY (0460)?
I have also rebuilt this whole topic as a complete Development unit for the 2027 syllabus: 5 modules with lesson slides, student workbooks, full answer keys and bonus interactive website access. Start with the free sample: https://www.tes.com/teaching-resource/resource-13453955

This is one of a growing collection of fully rebuilt 2026 geography lessons; more are on the way in my shop. If you find this useful, a review would mean a lot.

It’s how other teachers discover these resources, and it helps me keep creating.
