Ecosystems

Over the past few years, demand for seaweed has grown beyond its status as a long-lived local, seasonal harvest. Today it is used for fertilizer, health products, and as an additive to processed food. Rockweed has become vulnerable to larger corporate interests, yet another under-regulated natural resource that is under-managed, over-harvested, and over-exploited.

In a continuation of last week's episode, "Hard Edges," host Peter Neill argues that the hard edge has failed us, evidenced by storms that overwhelm barriers and destroy coastal structures. In this episode he will give examples of some of the slowly emerging examples of soft edge engineering and will ask, "How can we turn the new circumstances brought on by sea level rise to our advantage?"

Our traditional approach to protection from sea and surge has been the hard edge, with the mission to shield us from the encroachment of water. In this episode of World Ocean Radio, host Peter Neill will take us through the history of the industrial management of ports, wetlands and watersheds and will share some modern examples of "hard edge" engineering and the challenges for existing structures in the face of projected sea level rise, extreme weather and coastal flooding.
