Assess students' ability to apply social-studies and systems-thinking skills by designing a sustainable land-use and economic plan for a hypothetical small coastal town facing sea-level rise, rising tourism, and a declining fishing industry. Students should identify and justify climate-adaptation options (e.g., managed retreat, natural buffers, elevation, zoning), propose land-use changes and economic diversification strategies (e.g., eco-tourism, sustainable aquaculture, small business support), address stakeholder impacts and equity, provide a phased timeline with priority actions and basic cost considerations, and explain trade-offs and policy tools used to balance environmental resilience and local livelihoods. Include space for a simple map or diagram and evidence-based reasoning.
