Regenerative Skills

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.

Successful design and construction of wetlands, with Tom Biebighauser

One of the most crucial natural environments for the health and stability of landscape hydrology are wetlands. They also usually happen to be areas of the highest density of wildlife and biodiversity when they are healthy and functioning well. At the same time wetlands in all their different forms are highly endangered, being the targets for milenia of drainage and infill in order to make use of them for cultivation. Yet recovering and rebuilding wetlands is not only possible, it can be an affordable and context appropriate way of regenerating the health of entire water catchments as well. Here to shed light on the topic of wetland construction and design is Tom Biebighauser, the founder of Wetland Restoration and Training LLC which was was established in 2014 with the mission of encouraging and helping people to build naturally appearing and functioning wetlands. 
 
Tom had heard from many landowners and natural resource managers that it was almost impossible for someone to learn how to build a wetland, and that actually building wetlands was extremely expensive. To make matters worse, the few people building wetlands were using techniques with a success rate of less than 50-percent.
 
Tom learned how to build wetlands, streams, ponds, and lakes the hard way through trial and error. Building his first wetlands in Minnesota in 1979 while working for the US Forest Service, he has since built thousands of wetlands. Less than one-half of the early wetlands he built held water as planned. Over time, through much anguish and relentless work, he developed innovative techniques for constructing wetlands that are consistently 100-percent successful and low cost.
 
Tom Biebighauser has been enthusiastically restoring wetlands, lakes, streams, and rivers since 1979. He has designed over 10,000 wetland projects and has successfully supervised the construction of over 3,000 wetlands and streams in 26-states, 3-Canadian provinces, Mexico, New Zealand, Puerto Rico, and Taiwan. 
 
Tom enjoys leading workshops where participants can learn about wetland restoration by designing and constructing wetlands from start to finish. 
Tom has developed highly successful and inexpensive techniques for restoring wetlands and streams that should last forever without maintenance and that provide habitat for endangered and threatened species. 
 
In this interview Tom and I go into quite a lot of detail about wetlands, covering the range of configurations and biomes they appear in, and how prominent and integral to landscape health they have been in areas we now consider arid and degraded. We explore the criteria for selecting a wetland construction site, as well as the design criteria and process in order for it to fit well and function in any landscape. 
Tom also explains the all important maintenance and monitoring process once the wetland is installed and we even explore the unique opportunities that exist to integrate wetlands into farms, schools, communities, and many other managed landscapes that have traditionally drained and dismantled wetlands in the past. This episode is going to kick off a series of water focused episodes, some of which I’m bringing back from the archives because there are many new listeners who haven’t heard them and they’re worth revisiting, and new conversations as well as I look into the specific context of water management challenges and potential here in Spain and the Iberian Peninsula. I also have some exciting announcements that will be rolling out at selected intervals throughout this series. It’s still a little early to say, but I can tell you that if you’re passionate about supporting regional scale water regeneration and the possibility of turning this type of work into a career, then be sure to stay up to date during this run.

The story of soil through a microscope, with Isadora Schmidt

Continuing with my series highlighting badass local people around my community here in Spain, I was really pleased to be able to share this conversation that I had with a new close friend of mine and soil health advocate extraordinaire, Isadora Shmidt. I was first passed Isa’s contact by another good friend, Noemi, who is also part of the Soil Food Web graduate network. Isa created Terra Viva, her consulting and soil analytics company operating from her home base of Manresa, a small city about an hour west of me. She has a very diverse background which you’ll hear in a minute but principally she describes herself as a microbe farmer, driven by a deep concern for food security and a love for the natural world. She dedicates her work to regenerate soil health through the power of microbes and ecosystems. With a focus on tailor-made compost and liquid amendments, she partners with farmers and growers to restore soil microbiota and promote sustainable agriculture. Isa is also passionate about fostering connections within the agricultural community and continuously learning about the latest advancements in soil science. I’ve gotten to know her as an incredible connector who has partnered with many of the institutions and leading practitioners in our region while helping to make connections between all of them in order to advance the broader movement of regeneration in our region. 
This is another special opportunity for me since she came to my farm to take soil samples for me in this year’s round of measurement and monitoring of the health and ecological function of the farm. I already have a lot of data points from ecological monitoring, and so soil microscopy adds an incredible depth and dimension to the larger story of soil health that I’m working to build.
In this episode we start with a quick review of the activities of the day and what we learned together from the initial analysis of the soil samples we took and looked at under the microscope. Isa does a wonderful job of explaining in simple terms the incredible range of life and activity that can be seen in this form of analysis as well as what it means in practical terms. She also shares her learnings and impressions from looking at soil samples from farms all over the region and what it means for the work ahead for the farmers who manage the soil.
