Maritime Boundaries & Law of the Sea

Active learning works because maritime boundaries are complex and spatial, needing hands-on mapping and negotiation to grasp layered jurisdictions. Debates and simulations help students internalize how abstract legal concepts like UNCLOS translate into real-world conflicts and cooperation.

Activity 01

• Case Study Analysis
• 45 min · Pairs

Map Lab: Delineating EEZs

Provide world maps and rulers marked in nautical miles. Students measure and shade EEZs for select coastal countries, noting overlaps. Discuss resulting disputes in pairs before sharing with the class.

Explain the concept of an Exclusive Economic Zone (EEZ) and its significance for coastal states.

Facilitation Tip

During the Map Lab, circulate with a red pen to correct EEZ overlaps and ask guiding questions like, 'Which article of UNCLOS applies here?'

What to look for

Pose the question: 'If a coastal state has sovereign rights to resources in its EEZ, what are its responsibilities towards international shipping and environmental protection within that zone?' Facilitate a class discussion, guiding students to consider UNCLOS articles related to navigation and environmental duties.

Activity 02

• Case Study Analysis
• 50 min · Small Groups

Debate Circle: UNCLOS Effectiveness

Divide class into teams representing coastal states and international bodies. Assign pro and con positions on UNCLOS enforcement. Teams prepare arguments using case studies, then debate in a structured circle format.

Analyze how disputes over maritime boundaries can lead to international conflict.

Facilitation Tip

In the Debate Circle, assign roles such as 'Coastal State Advocate' or 'Freedom of Navigation Representative' to ensure balanced perspectives.

What to look for

Provide students with a map showing a fictional coastline and several disputed maritime zones. Ask them to identify the territorial sea and EEZ for the coastal state, and to label one potential area of conflict based on resource distribution or shipping routes.

Activity 03

• Jigsaw
• 60 min · Small Groups

Jigsaw: Maritime Disputes

Assign expert groups one dispute, like Spratly Islands or Arctic routes. Groups analyze causes, UNCLOS application, and outcomes, then jigsaw to teach home groups. Conclude with whole-class synthesis.

Evaluate the effectiveness of UNCLOS in regulating activities in international waters.

Facilitation Tip

For the Case Study Jigsaw, assign each group a different dispute to deepen analysis, then have them teach their case to peers in mixed groups.

What to look for

Ask students to write down one specific example of a maritime dispute they learned about and explain how UNCLOS was either used to address it or why it was insufficient. Collect these to gauge understanding of conflict analysis and treaty effectiveness.

Activity 04

Negotiation Simulation: Boundary Talks

Pairs represent two nations with overlapping EEZ claims. Using provided data on resources and law, negotiate agreements. Debrief on compromises and UNCLOS principles as a class.

Explain the concept of an Exclusive Economic Zone (EEZ) and its significance for coastal states.

Facilitation Tip

During the Negotiation Simulation, assign a timekeeper and notetaker to each group to document compromises and sticking points.

What to look for

Pose the question: 'If a coastal state has sovereign rights to resources in its EEZ, what are its responsibilities towards international shipping and environmental protection within that zone?' Facilitate a class discussion, guiding students to consider UNCLOS articles related to navigation and environmental duties.

A few notes on teaching this unit

Teachers should start with concrete examples before abstract principles, using real-world disputes like the South China Sea to ground discussions. Avoid lecturing on UNCLOS articles upfront; instead, let students discover rules through activities and then reference treaty texts. Research shows that role-plays and negotiations build empathy and deeper understanding of treaty limitations, especially when students represent countries with conflicting interests.

Successful learning looks like students confidently mapping EEZs, citing UNCLOS articles in debates, analyzing case studies with geographic and legal evidence, and negotiating boundaries with clear justifications. They should connect these activities to broader themes of resource management and international cooperation.

Watch Out for These Misconceptions

• During the Map Lab, watch for students labeling entire EEZ areas as sovereign territory.

  Use the EEZ coloring guide to highlight that only the territorial sea (12 nautical miles) grants full sovereignty; the EEZ (200 nautical miles) grants economic rights only. Ask students to label the 'innocent passage' corridor and fishing zones distinctly.

• During the Debate Circle, listen for claims that UNCLOS settles all disputes automatically.

  Direct students to UNCLOS Article 298, which allows countries to opt out of dispute resolution. Have them reference the South China Sea tribunal case as an example of ignored rulings to shift the conversation.

• During the Negotiation Simulation, observe students assuming maritime boundaries are fixed once agreed upon.

  After each round of negotiations, pause to ask, 'What geographic or political factors might change this boundary in 20 years?' Use the Arctic Ocean ice melt scenario to prompt dynamic thinking.
