Coasts: Soft Engineering

The video discusses coastal degradation and management strategies. It contrasts hard engineering solutions, which are costly and short-term, with soft engineering solutions that are sustainable and environmentally friendly. Examples of soft engineering include beach nourishment in Cancun and sand dunes stabilisation. Managed retreat is highlighted as the most eco-friendly approach, allowing natural processes to create new coastal landscapes.
