ABOUT THIS EPISODE

Growing Coral and Building a Restoration Economy with Sam Teicher

Coral reefs are easy to love when we see them. Colour, movement, abundance, that feeling of being inside another world.

But in this conversation, Sam Teicher helps us see reefs in a deeper way. Not as a holiday backdrop, but as living infrastructure that holds whole coastlines together. Food systems. Livelihoods. Biodiversity. Culture. Medicine. Protection.

Sam is the co founder of Coral Vita, an Earthshot Prize winning reef restoration company growing corals on land and replanting them back onto damaged reefs. What I appreciated most in our conversation was the combination of clarity and practicality. The ocean is warming. Reefs are under enormous pressure. And still, there are meaningful actions we can take to support repair, resilience, and recovery.

“Coral reefs take up less than 1% of the sea floor. They sustain 25% of marine life.”

Reefs are not just beautiful, they are protective

One of the most striking parts of this episode is the way Sam describes reefs as coastal protection systems. Reefs break wave energy. They reduce storm surge. They protect lives, homes, roads, and water infrastructure.

And in a warming world with more intense storms, this matters more each year.

“They are the best seawalls we can ask for. They don’t cost anything to build. They are self repairing.”

Sam also shares how this reframing is already changing behaviour in places you might not expect, including insurance and reinsurance. When reefs protect property, restoration becomes risk reduction. The logic changes.

Coral bleaching, and the reality of heat stress

We unpack what coral bleaching actually is and why it is happening so often now. This matters because bleaching is often spoken about in vague ways, but it is a real physiological stress response. When temperatures stay too high for too long, corals lose the algae that feed them and give them colour. Without recovery, they starve.

Sam speaks honestly about the speed of change and the scale of the challenge. At the same time, he highlights something important. Not all reefs respond the same way. There are pockets of resilience, and there are genotypes and species that tolerate heat better than others.

That is where the work of selection, propagation, and protection begins.

Growing corals on land, and why that is useful

Coral Vita’s model is land based coral farming. It is a practical response to a practical problem. If you can control water conditions, light, temperature, and nutrient flows, you can grow coral more efficiently and with greater survivorship.

Land based systems also support careful monitoring and experimentation. What survives. What grows well. What handles stress. What is suited to specific sites.

In the episode, Sam shares why land based nurseries can complement ocean nurseries and why the goal is not just more coral, but the right coral for the right place, with diversity and long term ecosystem function in mind.

Assisted evolution, and the ethics of intervention

We also talk about assisted evolution, a field that has emerged as scientists and practitioners look for ways to increase resilience in coral populations under rising temperatures.

This is a tender area. Intervention in living systems always deserves careful ethical attention. What I appreciated was Sam’s grounding in the reality that we are already intervening, through emissions, pollution, and coastal development. The question is whether we intervene with care, humility, and ecological intelligence, or keep intervening by accident and denial.

The restoration economy

A major thread in this conversation is what Sam calls a restoration economy.

In simple terms, if we want restoration at the scale the moment requires, it cannot rely only on grants and goodwill. It needs durable funding pathways. It needs models where reef dependent businesses, governments, and institutions invest in restoration as a form of protecting the very systems their economies depend on.

This is one of the places where this conversation aligns beautifully with permaculture thinking. We design systems where care is built into the structure. Where the ongoing health of the whole is not an optional extra, but a core function.

When restoration becomes normal economic behaviour, not a special project, we move from emergency response toward long term stewardship.

Ridge to reef, and why permaculture belongs in this conversation

One of the things I kept thinking as we spoke was this. Coral restoration cannot be separated from what is happening on land.

Sediment runoff, nutrient pollution, sewage leaks, chemical flows, plastics, coastal clearing, heat island effects, port development. All of these land based dynamics travel downstream.

Permaculture helps us widen the frame. It invites us to design from catchment to coast, from household to harbour, from soil to sea. Reef health is connected to how we farm, how we build, how we manage water, and how we live with place.

This is not just an ocean story. It is a whole systems story.

A few lines that stayed with me

“The closest many of us will get to being an astronaut and visiting an alien planet is scuba diving and going down to these reef ecosystems.”

“There are medicines on the market… that come from coral reef organisms.”

These are reminders that reefs are not only important. They are astonishing. They are alive with more intelligence and interdependence than most modern systems can fathom.

ABOUT THIS PODCAST

The Sense-Making in a Changing World podcast is an initiative of the Permaculture Education Institute hosted by Morag Gamble. It is broadcast from a solar powered studio in the midst of a permaculture ecovillage food forest on beautiful Jinibar and Gubbi Gubbi country.

We explore ‘what now’ – what thinking do we need to navigate a positive and regenerative way forward; what does a thriving one-planet way of life look like; and where should we putting our energy.
