Assess learners' ability to design a comprehensive, evidence-based coastal community plan that integrates climate adaptation (risk assessment, engineered and nature-based measures), decentralized renewable energy systems (distributed generation, microgrids, storage, demand management), biodiversity conservation (habitat protection, restoration, connectivity, ecosystem services), and socio-economic equity policies (inclusive governance, equitable financing, livelihood resilience, managed retreat). Require synthesis of trade-offs, monitoring indicators, implementation timeline, stakeholder engagement strategy, and justification of technical and policy choices.
