Challenges to Food Security: Water Scarcity

Active learning builds empathy and critical thinking for complex global issues like food security and water scarcity. Students move beyond facts to analyze real-world impacts and collaborate on solutions, which strengthens retention and engagement with this challenging topic.

Activity 01

Problem-Based Learning45 min · Pairs

Mapping Activity: Global Water Scarcity Hotspots

Provide maps and data sets on water scarcity indices. Students in pairs identify patterns, annotate causes like climate and overuse, and link to food production declines in three regions. Conclude with a class share-out of findings.

Analyze the causes of water scarcity in different regions and its link to food production.

Facilitation TipFor the Mapping Activity, provide students with blank world maps and colored pencils to visually compare water scarcity data across regions during group work.

What to look forPose the question: 'Imagine you are a farmer in a region experiencing severe water scarcity. Which two unsustainable water practices would you stop immediately, and why? What two sustainable practices would you adopt, and what challenges might you face in implementing them?' Facilitate a class discussion where students share their reasoning.

Activity 02

Jigsaw60 min · Small Groups

Jigsaw: Regional Impacts

Divide class into expert groups on Australia, Middle East, and Africa cases. Each group researches causes and food security links using provided sources, then jigsaw teaches peers. Groups create infographics summarizing key points.

Explain how unsustainable water management practices contribute to food insecurity.

Facilitation TipWhen running the Case Study Jigsaw, assign each group a different region and require them to prepare a two-minute summary using a graphic organizer to focus their discussions.

What to look forProvide students with a short case study describing a fictional agricultural community facing water scarcity. Ask them to identify one cause of the scarcity and one consequence for food security, writing their answers on a sticky note to be placed on a class chart.

Problem-Based Learning50 min · Whole Class

Solution Design Challenge: Whole Class

Pose a scenario of a water-scarce farm. Students brainstorm and vote on efficiency solutions like permaculture or tech aids, then prototype one using simple materials. Discuss feasibility and trade-offs as a class.

Evaluate potential solutions for improving water efficiency in agriculture.

Facilitation TipDuring the Solution Design Challenge, set a timer for brainstorming to keep the whole class on task and ensure every group contributes at least one idea to the shared solution list.

What to look forOn an index card, have students define 'water scarcity' in their own words and list one specific agricultural impact. Then, ask them to suggest one innovative solution that could help improve water efficiency in farming.

Debate Pairs: Practices vs Solutions

Pair students to debate unsustainable practices versus proposed fixes. Each side prepares evidence on food insecurity links, presents, and switches roles. Wrap with class consensus on best actions.

Analyze the causes of water scarcity in different regions and its link to food production.

Facilitation TipIn Debate Pairs, require students to use at least two evidence-based reasons to support their arguments and provide a counterpoint to their partner’s claim before switching roles.

What two sustainable practices would you adopt, and what challenges might you face in implementing them?' Facilitate a class discussion where students share their reasoning.

A few notes on teaching this unit

Start with a clear connection between water scarcity and food security using accessible examples, such as local produce prices or news stories about droughts. Avoid overwhelming students with too much data initially; instead, build their understanding progressively through structured activities. Research shows that role-based and problem-solving tasks increase comprehension and retention of global issues among secondary students.

Students will confidently explain how water scarcity affects food security and evaluate both causes and solutions using evidence. They will demonstrate collaboration in group work and articulate nuanced perspectives in discussions and debates.


Watch Out for These Misconceptions

  • During Mapping Activity: Global Water Scarcity Hotspots, watch for students who assume scarcity only occurs in deserts.

    Use the mapping activity to have students compare arid regions with high agricultural output areas like California’s Central Valley or Spain’s Mediterranean zones. Ask them to note how scarcity in these fertile zones stems from over-extraction and climate variability, not just natural aridity.

  • During Solution Design Challenge: Whole Class, watch for students who believe technology alone solves water scarcity.

    Use the solution design process to require students to evaluate both technological and management-based solutions. Ask them to consider cost, accessibility, and environmental trade-offs, ensuring they recognize that technology must work within sustainable systems.

  • During Case Study Jigsaw: Regional Impacts, watch for students who view food insecurity as a temporary or isolated issue.

    Use the jigsaw activity to have groups trace supply chains and migration patterns linked to water scarcity. Ask them to present how water shortages in one region can ripple globally through trade and refugee movements.
