One of the best lines of defence against tidal wave damage has proven to be coral reefs, which weaken a tsunami’s impact before it hits shore. The devastating effects of the Sumatra tsunami from 2004 could have been greatly reduced if the coral reefs off the coast of Sri Lanka hadn’t been largely removed by humans.
There are a number of coral regeneration projects in operation worldwide. A method developed by architect Wolf Hilbertz involves submerging steel structures charged with an electric current which draws calcium carbonate onto the surface of the structure, creating a magnet for new coral to feed on.

Back in 1973 when Jacques Cousteau advocated fish farming as a way out of the destruction of the world's fish stocks, it seemed like a good idea. Forty years later, aquaculture is the world’s fastest growing industry and nearly half of all seafood is farmed - but the ecological damage it causes is quite shocking. Aquaculture needs to get sustainable and a system of “integrated multi-trophic aquaculture” seems to be the way forward: the co-culture of a number of species at different trophic levels in niche systems which help regulate much of the harm caused by current monoculture practices. Projects underway include the AquaFish Collaborative Research Support Program in Thailand and Indonesia, which combines production of tilapia, mud crabs, seaweeds, milkfish, and mussels.

In Northwest Alaska permafrost is melting, sea levels are rising, and entire villages are falling into the sea. The whaling community of Kivalina, home to some 400 people, is facing imminent relocation and the need for viable futures is urgent. For a host of reasons, previous relocation efforts in Kivalina are stalled, leaving the community looking for alternatives. ReLocate, a group of social artists from around the world are using social media to initiate a new, kind of community-led and culturally specific relocation. p
