Regenerative Skills

The massive potential of marine permaculture, with Brian Von Herzen

Continuing today with this ongoing series on waterway regeneration and a deep dive into marine ecosystems, I had the pleasure of speaking with Brian Von Herzen. 
Brian is an ocean scientist, engineer and entrepreneur, though much of his career has been in Silicon Valley where he developed innovative technical solutions for companies like Pixar, Dolby and Microsoft. Brian is also the founder and Executive Director of the non-profit The Climate Foundation, an institute working to regenerate life in the world’s oceans and reverse global warming within our lifetimes.
Through Brian’s work with the Climate Foundation, he’s been promoting the concept of marine permaculture through ocean seaweed and kelp farming in a way that could potentially revitalize areas of degraded coastline as well as spark a whole new economy around marine ecosystem stewardship. 
In this interview, Brian starts by explaining just how immense and important the kelp forests of the world are by describing the impact that they’ve had on the ecology of the west coast of the United States. I think it’s so important to regain reference to what our healthy and intact biosphere used to be, because all of us alive today have almost no reference to what our natural world even looked like before humans started to alter and degrade it so severely. 
Brian also breaks down what it could mean for the economy and health of the west if these underwater forests could be regenerated and cared for. 
We also explore some of the challenges in getting sea farming and ocean permaculture projects started and especially funded, since the initial costs are often much higher than land based initiatives.
We cover a lot of ground in this talk and even touch on topics like how marine farming fits into a regenerative economy and what those of you listening can do to support and even start your own marine permaculture projects, so be sure to stick around for some great action steps by the end.

Diving deep into ocean farming, with Joost Wouters

Today I want to continue with a deeper dive into the topic of water, literally, by going to the furthest point downstream, where terrestrial water enters the ocean. 
Marine ecosystems are much less understood by the general public for a variety of reasons, but our actions on land have a direct effect on the health of our oceans too. Luckily there are incredible teams of people looking to address these issues with promising new solutions and over the next couple of episodes I’ll be highlighting a few of them. 
To get things started I spoke to Joost Wouters, an entrepreneur, speaker, author and the ‘Sea’EO of the Seaweed Company. I got to know Joost first as a co-instructor with me on the Ecosystem restoration design course through Gaia Education. I was fascinated with his presentation and the compelling data on the potential regenerative effects that seaweed and kelp can have in bringing back the health of coastal areas. In his role with the Seaweed Company, he and his team aim to implement CO2-reducing seaweed-based business models at large scale.
It turns out that seaweed is the fastest growing biomass in the world. Seaweed farming itself, if done responsibly, has the power to address many of the ecological challenges we face today, without the use of land, fertilizer, or freshwater. It reduces ocean acidification, promotes marine biodiversity, and even absorbs vast quantities of CO2 from the atmosphere.
Seaweed can also create highly valuable end products. It is a nutritious food source for both people and animals and can be used as an environmentally friendly alternative to petroleum-based fertilisers and plastics. At the moment it’s a unique untapped resource, and the goal of the Seaweed Company is to unlock the potential of this wondrous resource to benefit both people and the planet.
In this episode Joost starts by explaining some of the urgent issues facing marine environments and how seaweed farming can help to address them. We go over the advantages that growing seaweed has over terrestrial agriculture, the high value products that can be made from different types of seaweed, the many pilot projects around the world that his company has helped to start and much more. 
Towards the end we also examine the roadblocks that are holding this solution back from being more widely adopted and how those of you listening can learn more and get involved. 
I’ve personally been learning a lot about marine ecosystems through these interviews and truly hope that a greater awareness will begin to be built around just how essential the health of our oceans is to the health of all life, even to ecosystems that are far inland and away from any saltwater. I’m really excited for this and the next few episodes for this reason.

Why regenerating our oceans makes both public health and economic sense, with Dr. Enric Sala

While the climate change narrative has mostly focused on the concentration of CO2 and other greenhouse gasses in the atmosphere since the industrial revolution, we’ve ignored the essential role that the water cycle plays in regulating global temperatures. In this series I’ll be speaking to an incredible list of scientists, farmers, and restorationists who are dedicated to reviving the precious waterways of the world. From the urban environment to the deep seas, our actions will determine whether or not we preserve our aquatic resources and all the life that depends on them for future generations. 
 
In this first episode I got to speak with Enric Sala, a renowned ecologist making a clear case for why protecting nature is our best health insurance, and why it makes economic sense. Enric is the director of National Geographic’s Pristine Seas project (which has succeeded in protecting more than 5 million sq km of ocean and created 22 marine reserves). Dr. Sala has received the Young Global Leader Award by the World Economic Forum, a Research Award from the Spanish Geographical Society, the Lowell Thomas Award from the Explorers Club, and a Hero Award from the Environmental Media Association. In his new book “The Nature of Nature: Why We Need the Wild,” he tells the story of his scientific awakening and his transition from academia to activism. More importantly, he shows the economic wisdom of making room for nature, even as the population becomes more urbanized, and how saving nature can save us all, by reversing conditions that led to the coronavirus pandemic and preventing other global catastrophes.
In this interview we begin by unpacking the changes that have occurred in our oceans in the last few decades and how this is affecting people all over the world, even if you don’t live anywhere near the sea. 
Enric also offers a lot of hope that our oceans can recover if we act swiftly and give them the space and protection to regenerate. 
I learned a lot from this talk and as I begin to learn more about how marine health is closely linked to terrestrial health, I would encourage those of you listening to examine how your own habits and lifestyle choices are connected to ocean health in ways that can be hard to see. 

Regenerative earthworks for water retention landscapes, with Douglas Barnes

My guest today is here to demystify one of the aspects of permaculture design that I hear the most questions about, but also one of the issues that I see folks most entrenched in their viewpoints about. I’m talking about earthworks; one of the first aspects that people implement and the most permanent change made in a landscape. Today I’ve got Douglas Barnes, author of “permaculture earthworks” and owner director of EcoEdge Design Ltd. to answer our questions and take the guess work out of the subject of terrain changes.
In this interview Douglas talks about the best way to map out contours on the land, some of the most effective ways to harvest rainwater on a site, how to link up various earthwork and containment systems to make them work in tandem, and most importantly, he talks in detail about many of the safety concerns that many people have no idea about when it comes to installing swales and dams.

The permaculture guide to earth surgery, with David “Doc Spice” Spicer

 I spoke with David Spicer, affectionately known as Doc Spice, an accomplished permaculture designer who has specialized in earthworks installation. Having taught and worked on various projects extensively within Australia and internationally, in places such as Morocco, Jordan, Palestine and New Caledonia, Doc has worked in a broad array of different soil types, topographies and climatic zones.
He’s also a valued member of the Permaculture Sustainable Consulting team headed up by Geoff Lawton and is registered Teacher #5 with the Permaculture Research Institute of Australia.
Doc is a master of practical and logical mainframe permaculture design and he’s pioneered the design of water harvesting and storage earthworks which frames all regenerative farming.In this episode we talk about why it’s so important to invest early on in a project to get your earthworks right because of what it can mean for the health of your land. Doc also shares some insights on his personal design process and what he looks for in a landscape to give him clues as to the most effective interventions on the form of the land. We also cover some of the risks of improperly installed features, the need to draw from as many sources of knowledge as possible and he also gives some valuable advice for people who are new to earthworks on how to get started. 

The essentials of rainwater harvesting, with Rob Avis

In keeping with the theme of water regeneration this month I spoke to Rob Avis, the co-author along with Michelle Avis of their book in the New Society Essentials series called Rain Water Harvesting.
Rob and Michelle founded Verge Permaculture, an award-winning design, consulting and education company in Calgary, Alberta after years of international training in renewable energy and regenerative design. Since its founding, Verge has helped more than 1000 students and clients to design and create integrated systems for shelter, energy, water, waste, and food, all while supporting their local economy and regenerating the land. Through their design and consulting they create havens that produce their own energy and food, harvest water, cycle nutrients, and restore the surrounding ecosystems, enabling property owners to thrive no matter what. With such a broad range of knowledge, experience, and expertise, we focused mainly on rain water harvesting techniques and systems in this episode as an entry into the larger concept of watershed regeneration and revival.
In this session Rob explains some of the key components of rain water harvesting systems and the ways that you can treat and filter the water for various uses. We talk at length about why expensive filters and disinfectants are often unnecessary, even for most potable water uses, and the different ways you can keep your stored rainwater clean. Rob also speaks about how rainwater harvesting systems fit into a larger system aimed toward water resilience in multiple living contexts from urban to rural applications. I’ve been a big fan of Verge Permaculture and all their great work for some time now and I’m intending to create a larger series of in depth talks with Rob and Michelle in the future 

How to plant the rain in drylands and beyond, with Brad Lancaster

If at any point you’ve been interested in water harvesting in dryland contexts, it’s almost impossible that you’ve missed Brad Lancaster’s work. His pioneering activities and projects in Tucson, AZ have propelled a movement of water wise landscaping, rainwater harvesting, and smart water reuse all around the world. While so many of the examples I’ve highlighted in this series relate to actions and strategies for working with the land, a huge majority of Brad’s work is focused on the urban and suburban context with everything from roof water, to road and storm drain diversion, and greywater and systems. 
In the last handful of episodes we’ve explored permaculture earthworks for water harvesting landscapes and keyline design on large scales. As a complement to those topics I got in touch with Brad Lancaster, the author Rainwater Harvesting for Drylands and Beyond, volumes one and two which have recently been re-released as expanded new editions.Brad is an expert in the field of rainwater harvesting and water management whose work I’ve been following for a long time. He is also a permaculture teacher, designer, consultant and co-founder of the non-profit Desert Harvesters, which teaches the public how to identify, harvest, and process many of the native-food plants people are propagating in their areas. He’s also been instrumental in helping to change water management policy and government incentives in the City of Tucson to help others implement water wise catchment and reuse features on their properties. 
In this interview we cover a wide range of topics from the difference between active and passive harvesting technology and reading the landscape to determine how to work with the natural surroundings, to the increasing importance for water stewardship in non-arid climates and why it’s so important to connect and invest in the place you already live rather than thinking that moving to another place will solve your environmental worries. 
Brad also gives great advice on home scale water harvesting and storage which are all topics that are covered extensively in his books. He’s done an incredible job with the help of many experts and collaborators to compile tons of resources that are available to help you get started on his website

Repairing eroded and incised waterways, with Van Clothier

In today’s episode I spoke with Van Clothier about an innovative and subtle water erosion mitigation technique, and how to build a one rock dam.
I know this might seem oddly specific, but after an interview with Brad Lancaster last season, he talked about how he’s been learning from people like Van and his mentor Bill Zeedyk about smaller, less intrusive interventions that can have profound effects on the health of a watershed.
The truth is that there are so few watersheds and water bodies left around the world that aren’t highly degraded and in need of restoration.
Many of the communities most affected by this damage don’t have the resources to hire engineers and professionals to do survey and undertake large expensive restoration projects.
A lot of what Van promotes flies in the face of these large professional technical projects and teaches people how to understand their watersheds and identify the small and gradual work that can be done to improve their health.
The one rock dam is a great example of this and so today we’ll be exploring what it is, how it can be installed, and most importantly, how to educate yourself on how to interact and intervene in a damaged waterway in an effective way that doesn’t cause further damage in the long run, like many of these big professional projects do. 
So a little background information. 
Van Clothier’s firm, Stream Dynamics, Inc., specializes in turning runoff and erosion problems into water harvesting opportunities with water harvesting earthworks, urban stormwater retrofits, and riparian and wetland restoration in both urban and wildland settings.
Van has worked extensively in New Mexico and Arizona on a variety of restoration projects with regional drylands stream restoration and water harvesting experts including Bill Zeedyk, and Brad Lancaster. He is the co-author with Bill Zeedyk of the book Let the Water Do the Work: Induced Meandering, an Evolving Method for Restoring Incised Channels, 
Recent projects include designing water harvesting stormwater retrofits for the City of Santa Fe, and restoring a very large ciénega (desert marsh) in the bootheel of New Mexico.

Regenerating lakes and ponds with floating islands, with Bruce Kania

I had done one other episode in the past on the topic of floating wetlands that I’d like to revisit today as we continue with this series on regenerative water solutions. 
In today’s episode I got to speak with Bruce Kania of Floating Island International which developed their patented Biohaven floating island technology as a solution to algae-ridden and nutrient impaired waterways since 2005. Since then they´ve launched over 9,000 island systems worldwide as solutions to a variety of problems facing contaminated water. 
In this interview Bruce breaks down the chemical and biological processes that happen in the water when there’s a heavy nutrient load and how it affects the balance of oxygen and the lifeforms that depend on it. He tells me how the floating islands that he’s helped to develop work to cycle the nutrients of polluted waterways back into the food web that then fosters the beneficial life forms that are emergent elements of healthy water ecosystems and that mature to help the whole system and surrounding ecology to thrive. We also take a look at the case study of Fish Fry Lake in Montana and how it’s gone from a polluted lake with regular algae blooms to become the most productive wild fishery in Montana where people can even swim and snorkel!Be sure to stick around till the end of the interview as Bruce explains just how big the potential of these floating wetland systems is as he’s looking to develop inhabited floating islands that help to filter and clean the great plastic garbage patches in the Pacific ocean and the possibility of creating floating solar farms that function as new real estate as well. 

Reviving urban waterways with floating wetlands, with Galen Fulford

Today we’re going to take a look at fresh water systems and specifically, how to decontaminate them through biological methods.
Some of you may remember an interview I did with Tom Duncan about his floating wetlands and how they can be used to clean up excessive nutrients and pollutants back in season 1. Today I’ll be expanding on that technique since it´s gained a lot of traction and floating islands are popping up all over the world to help deal with contaminated rivers, lakes, and ponds. I’ll be sure to put a link to that interview in the show note on the website in case you missed it. 
For this episode I reached out to Galen Fulford, the managing director at Biomatrix Water, a biological technology company working on solutions for waterway and wastewater treatment based in Moray, Scotland. 
In this interview, Galen explains the science behind waterway contamination evaluation and the calculations they do to determine the restoration approach and techniques that are appropriate for each site. He also breaks down how their floating wetland systems work and how they compare and differ from traditional wetlands in the way they decontaminate water and provide habitat and sanctuaries for wildlife. We also explore the challenges that installing floating wetlands in urban environments can entail as well as some of the novel solutions in engineering that Biomatrix Water have developed to help their installations withstand events like floods and heavy contamination loads. 
This is a great episode for people who really want to understand the biology and engineering behind some of the most promising natural waterway remediation techniques being pioneered today. Make sure you listen all the way till the end too when Galen explains how these floating wetland systems are being applied to ecological sewage treatment and municipal water purification.
