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.

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.

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

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.

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. 

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.

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.

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.

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.

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.

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.

I have to admit, there is an unsung hero behind many of my favorite interviews of the past couple years. Connections and recommendations to some of the people who I’ve learned the most from in some recent discussions with people like Phyllis Van Ambraugh, Ben Taylor Davies, Ian Robertson, Ed Brown, and others have all come from a good friend of mine Andre Antunes who you’ll finally get to know on this episode.

Since that first meeting we’ve been in close contact as we both work closely with farmers in the company network to assist them in their transition to regenerative management of their farms, and Andre has gone on to manage large transition projects with multinational companies which you’ll hear about very soon.

As I continue to make connections and find people in my local area who are working on regenerative projects and supporting progress in Spain and the Iberian Peninsula, I’ve been amazed at the talented, courageous, and inspiring people that I’ve come into contact with.

For this episode, I had the rare pleasure of hosting Meghan at my own farm, even though we’re in the middle of construction and the place is a disaster. She was passing through in between training events in my area of Catalunya, and I couldn’t pass up the opportunity to show her what my partner Alba and I are working on.

Today we’ll be continuing with the second part of my discussion with Anne Van Leeuwen from Bodemzicht in the Netherlands.

We explore complementary farm enterprises to ensure regular cash flow, navigating the complexities of human relationships within a multistakeholder business, and by the end we also go over her membership and participation with the European Alliance for Regenerative Agriculture, or EARA, a new lobbying organization working to shape regenerative ag policy at the European Union level. 

Today’s conversation is the first of a two part conversation with Anne Va Leeuwen from Bodemzicht in the Netherlands that I’ve been looking forward to for quite a few years.
