12.1 Principles of ICZM

Integrated Coastal Zone Management (ICZM) is a holistic approach to managing coastal areas, balancing development with environmental protection. It addresses complex interactions between land and sea, promoting sustainable use of resources while maintaining ecological integrity.

ICZM plays a crucial role in coastal resilience engineering by integrating environmental, economic, and social objectives. It emphasizes cross-sectoral coordination, land-sea interactions, and multi-stakeholder engagement to tackle challenges like coastal erosion, pollution, and climate change impacts.
