987: Rules for Global Seed Saving with Bill McDorman
1w ago00:45:00Tap to summarizeJoin our monthly Seed Chat at SeedChat.orgIn This Podcast: In this monthly Seed Chat, Greg Peterson and Bill McDorman explore the global rules governing seed ownership, seed saving, biodiversity, and agricultural policy. The conversation dives into international treaties, plant patenting, farmers’ rights, and the growing tension between the Global North and Global South over control of genetic resources. Bill shares firsthand experiences attending United Nations treaty negotiations and working with Indigenous seed sovereignty issues through Native Seeds/SEARCH. The episode also highlights why everyday gardeners and farmers should become “seed citizens” by saving and sharing locally adapted seeds.Bill McDorman is a renowned seed saver, educator, and advocate for agricultural biodiversity. He co-founded the Rocky Mountain Seed Alliance and has spent decades teaching gardeners and farmers how to grow, save, and share heirloom seeds. Through workshops, speaking, and mentorship, Bill inspires communities to strengthen local food systems, preserve regional seed diversity, and protect seed sovereignty for future generations.Key TopicsSeed libraries and locally adapted seed sharingInternational Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA)UPOV and global plant variety protection lawsWorld Trade Organization (WTO) seed policy influenceFarmers’ rights and seed sovereigntyPlant patenting and intellectual property in agricultureConvention on Biological Diversity (CBD)Nagoya Protocol and access-benefit sharingDigital Sequence Information (DSI) and genetic ownershipNative Seeds/SEARCH and Indigenous seed stewardshipOrganic Seed Alliance and seed policy debatesGlobal North vs. Global South agricultural power dynamicsSeed banks and the Multilateral System (MLS)The importance of saving open-pollinated seedsThe future resilience of local food systemsKey Questions AnsweredWhat is the International Treaty on Plant Genetic Resources for Food and Agriculture?The ITPGRFA is a legally binding international treaty created to govern the conservation, sharing, and equitable use of plant genetic resources for food and agriculture. It officially entered into force in 2004 and now includes participation from more than 180 countries.Why do global seed treaties matter to everyday gardeners and farmers?These treaties influence who can save seeds, who profits from plant genetics, and how agricultural biodiversity is preserved. The policies affect food security, seed availability, farmer independence, and long-term resilience of local food systems.What is UPOV and why is it controversial?UPOV is an international agreement that grants intellectual property protections to plant breeders. Critics argue that newer versions of UPOV weaken farmers’ traditional rights to save and replant seeds while strengthening corporate control over agriculture.How does the WTO influence seed laws around the world?According to Bill McDorman, countries seeking participation in global trade systems often adopt UPOV-style protections as part of WTO-related trade expectations, creating pressure on smaller nations to align with industrial seed systems.What is the Nagoya Protocol?The Nagoya Protocol is an international agreement designed to ensure fair and equitable sharing of benefits arising from genetic resources. It attempts to address historical exploitation of Indigenous and Global South biodiversity by pharmaceutical and agricultural corporations.What is Digital Sequence Information (DSI)?DSI refers to genetic sequencing data derived from crops and plant varieties. A major debate centers around who owns this information and whether communities that stewarded these crops for generations should share in the economic benefits created from their genetic data.What are farmers’ rights in global seed policy?Farmers’ rights include the ability to save, use, exchange, and sell farm-saved seed. These rights remain one of the most contested issues in international agricultural negotiations.Why are seed libraries important?Seed libraries help preserve locally adapted seed varieties while strengthening regional food resilience. They also create community networks for knowledge sharing and decentralized seed stewardship.How did Native Seeds/SEARCH navigate Indigenous seed stewardship?Bill shares stories from his time directing Native Seeds/SEARCH, including working with Zuni and Hopi communities to renegotiate relationships around seed stewardship, naming rights, and seed distribution.Why does Bill McDorman encourage people to attend UN treaty meetings?He believes participation in international seed policy discussions is critical for protecting biodiversity and farmers’ rights. Attending these events allows citizens, gardeners, and small farmers to directly engage with global agricultural policy.Episode HighlightsBill discovers a seed library inside a small-town New Mexico library and reflects on the importance of locally adapted seeds.Greg and Bill explain how seed laws emerged alongside industrial agriculture and large-scale seed commerce.Bill breaks down UPOV, WTO policy, and how plant patenting transformed global agriculture.The conversation explores how Indigenous plant genetics were historically extracted and commercialized.Bill recounts receiving a cease-and-desist letter regarding Zuni bean varieties while directing Native Seeds/SEARCH.A deep discussion unfolds around Digital Sequence Information and the ownership of plant DNA data.Bill explains why small farmers across Africa increasingly believe they no longer have the right to save seeds.The episode concludes with a call for more “seed citizens” actively saving and sharing seeds locally.ResourcesResource — Seed Chat Live Events — SeedChat.orgPodcast — Urban Farm PodcastOrganization — UPOV – International Union for the Protection of New Varieties of PlantsOrganization — World Trade Organization (WTO)Organization — Commission on Genetic Resources for Food and Agriculture (CGRFA)Treaty — International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA)Organization — Convention on Biological Diversity (CBD)Resource — Nagoya Protocol on Access and Benefit-sharingCommunity — Organic Seed AllianceOrganization — Native Seeds/SEARCHEvent — Great American Seed Up — First weekend in November in Phoenix, ArizonaVisit UrbanFarm.org/987 for the show notes and links on this episode!Need a little bit of advice or just a feedback on your design for your yard or garden?The Urban Farm Team is offering consults over the phone or zoom.

Transcribe →986: Feeding Dogs Smarter with Ryan Cole
2w ago00:36:24Tap to summarizeRaw Nutrition, Pawtrition, and the Future of Canine HealthIn this episode, Greg speaks with entrepreneur and canine nutrition educator Ryan Cole about the hidden problems with highly processed dog food and the growing movement toward raw feeding for dogs. Ryan shares the personal story that launched his mission after rescuing a pit bull with severe allergies and discovering how dramatically diet impacted the dog’s health and quality of life.The conversation explores kibble manufacturing, common ingredient red flags, raw feeding basics, portion control, canine obesity, treats, digestive health, and how personalized nutrition plans can improve a dog’s longevity. Ryan also introduces Pawtrition, an AI-powered dog meal planning platform designed to help dog owners create customized raw feeding plans based on breed, age, weight, and health goals.Our Guest: Ryan Cole is an entrepreneur and founder of Lineage Premier, a canine-focused health and nutrition company dedicated to empowering dog parents with better feeding guidance and nutrition education. He is also the creator of Pawtrition, a Lineage Premier product and AI-powered dog meal planning app designed to help pet owners feed smarter with personalized nutrition plans tailored to each dog's breed, age, weight, and health goals. Through his work, Ryan bridges practical pet care with education, helping dog parents move beyond the guesswork toward informed decisions that support long-term canine health and vitality.Key Topics & EntitiesRyan ColePawtritionLineage PremierRaw feeding for dogsHighly processed kibble and canine healthFood allergies in dogsPit bull rescue storiesCanine nutrition educationPersonalized dog meal planningBioavailable nutrients in raw dietsPortion control and canine obesityHealthy dog treats and frozen fruit snacksBreed-specific nutritionDigestive health and stool quality in dogsKey QuestionsWhat inspired Ryan Cole to focus on canine nutrition?Ryan’s journey began after rescuing a pit bull named Pops who suffered from severe allergic reactions to processed foods, shampoos, and synthetic materials. After switching to boiled chicken and rice and later researching raw feeding, Ryan saw dramatic health improvements that inspired him to dedicate his career to canine nutrition education.Why does Ryan believe highly processed kibble is problematic?Ryan explains that many kibble products are made from low-quality byproducts and heavily processed ingredients that are cooked at high temperatures, stripping away natural nutrients. Manufacturers then spray synthetic nutrients and fats onto the kibble after processing to improve flavor and nutritional labeling.What ingredients should dog owners watch for on labels?Ryan recommends paying close attention to the word “crude” on ingredient labels, especially crude proteins and crude fats. He also advises dog owners to read manufacturing warnings about cross-contamination from facilities processing allergens like nuts and grains.What does a healthy raw diet for dogs look like?A balanced raw diet includes raw meats, organ meats, vegetables, fruits, healthy fats, and oils. Ryan shares examples like chicken leg quarters, ground beef, chicken gizzards, green beans, duck eggs, and Alaskan fish oil.How does Pawtrition help dog owners?Pawtrition generates personalized 30-day meal plans based on a dog’s breed, age, weight, activity level, and health goals. The platform also includes budgeting tools, nutrition tracking, shopping assistance, veterinary checklists, and educational resources.Are most dogs overfed or underfed?Ryan says the bigger issue is often calorie-dense kibble rather than meal quantity itself. Because processed food is highly concentrated and less nutritionally bioavailable, dogs can gain weight even when owners believe they are feeding appropriate portions.What are signs a dog’s diet may not be working?Common warning signs include chronic itching, dull coats, digestive problems, inconsistent stool quality, scooting behavior, and excessive shedding or inflammation.Should dog owners rotate proteins and foods?Ryan recommends dietary variety whenever possible to improve nutrient diversity and prevent nutritional imbalances. Different proteins and vegetables offer different bioavailable nutrients and health benefits.What treats does Ryan recommend?Ryan prefers whole-food treats like frozen watermelon, blueberries, strawberries, and homemade fruit popsicles mixed with healthy fish oils instead of processed commercial treats.What drives Ryan’s work today?Ryan credits his mother’s work ethic and his lifelong passion for helping animals and people. He views Pawtrition and Lineage Premier as community-driven educational tools rather than simply businesses.Episode HighlightsRyan rescued his first pit bull, Pops, at age 17 after his father passed away.Pops suffered severe reactions to processed foods and synthetic products before transitioning to a raw diet.Ryan explains how kibble manufacturing prioritizes shelf life and profit margins over nutrition quality.Greg shares a story about healing a rescued golden retriever through raw feeding after medications failed.Pawtrition creates downloadable customized feeding plans for dog owners.Ryan discusses why working breeds like heelers should remain lean to protect joints and hips.The conversation highlights the importance of observing each individual dog rather than following generic feeding advice.Ryan recommends the book The Five People You Meet in Heaven by Mitch Albom for its message about interconnectedness and purpose.ResourcesPersonalized canine meal planning — PawtritionRaw feeding education and breed resources — Lineage PremierFollow Ryan Cole on Instagram, Facebook, and YouTube under “Lineage Premier”Visit www.urbanfarm.org/Pawtrition for the show notes on this episode, and access to our full podcast library!

Transcribe →985: Chickens, Compost & Food Resilience - A Rosie Replay
3w ago00:34:37Tap to summarizeA Rosie On The House ReplayIn this episode Romey Romero from Rosie on the House and Farmer Greg sit down with Ashley McClure and Scott Brown of Phoenix Organic Feed to talk about raising backyard chickens in the summer heat. The conversation explores heat management, predator protection, organic feed, egg production, breed selection, and why chickens are one of the best tools for local food resilience. Ashley and Scott also share the grassroots story behind Phoenix Organic Feed and how a small community feed order turned into a regional network serving thousands of chicken keepers across metro Phoenix and the Verde Valley.Key TopicsBackyard chickens in desert climatesOrganic chicken feed and local food resilienceHeat management for chickensPredator-proof chicken coopsEgg production and breed selectionChickens as composters and pest controlFood security through backyard farmingPhoenix Organic Feed community distribution modelRhode Island Red chickensLeghorn chickensRaising meat birds vs. egg layersElectrolytes and hydration for poultryVictory Gardens and modern homesteadingKey Questions AnsweredWhy should people keep chickens in their backyard?Chickens provide eggs, protein, compost, pest control, entertainment, and a stronger connection to food production. The guests describe chickens as a practical step toward food resilience and self-sufficiency.Can chickens survive desert heat?Yes. Chickens can adapt to desert climates when they have shade, cool water, ventilation, electrolyte support, and ways to cool their feet. Breed selection also matters because heavier feathered birds struggle more in extreme heat.What are the biggest mistakes new chicken keepers make?Underestimating heat stress, failing to predator-proof coops, and not planning for chick care are major mistakes. Baby chicks require supplemental heat, proper feed, protection, and clean water.How do chickens help gardens and homesteads?Chickens convert kitchen scraps, weeds, and insects into manure that improves soil fertility. They also reduce pests like scorpions and ticks while contributing to compost systems.What breeds are best for egg production?Leghorns and Rhode Island Reds are highlighted as strong egg producers, capable of laying close to 300 eggs per year under ideal conditions.Do colorful eggs taste different?No. The shell color does not change flavor, but presentation matters. Dark brown, blue, and green eggs create visual appeal and help backyard egg sellers stand out.Why start Phoenix Organic Feed?Scott Brown started the business after struggling to find affordable organic chicken feed in Phoenix. What began as a one-ton community order through a local permaculture network eventually grew into a distribution network serving over 3,000 subscribers.What makes backyard eggs different from store-bought eggs?The guests explain that backyard eggs often have darker orange yolks, fresher flavor, and come from chickens raised on higher quality feed and forage.Episode HighlightsChickens help control scorpions, ticks, and garden pests naturally.Roosters protect hens from predators and help maintain flock harmony.Chickens cool themselves through their feet, making shallow water trays effective in desert heat.Frozen water bottles, fans, and swamp coolers can save chickens during extreme Arizona summers.Egg production drops during stress, overcrowding, and intense heat.Older hens often become the best foragers and flock teachers.Chickens naturally roost high off the ground to avoid predators.Backyard eggs with colorful shells and rich orange yolks can command premium prices.ResourcesAshley & Scott's Website — Phoenix Organic Feed WebsiteVisit www.UrbanFarm.org/985 for the show notes and links on this episode!Need a little bit of advice or just a feedback on your design for your yard or garden?The Urban Farm Team is offering consults over the phone or zoom.

May 800:31:28Tap to summarizeIn this episode, Greg Peterson sits down with DePhane Weaver, founding president of the Garden Exchange Stands organization, to explore how neighborhood seed and plant sharing can strengthen local food systems and reconnect communities. Inspired by family traditions of gardening and generosity, DePhane shares how a simple neighborhood exchange evolved into a nonprofit network with hundreds of garden stands across Arizona and beyond. The conversation dives into food sovereignty, community resilience, pollinator support, permaculture principles, and the joy of sharing seeds, plants, tools, and gardening knowledge. DePhane explains how Garden Exchange Stands helps neighbors connect through a global interactive map and volunteer-driven community network. This episode is a powerful reminder that growing food is about more than harvests — it’s about relationships, local resilience, and creating spaces where people can give, learn, and belong.Our Guest: DePhane is the founding president of the Garden Exchange stands organization, inspired by family tradition of gardening and community service to FE champions, seed and plant sharings as a timeless way to connect neighbors, support wildlife and grow local food. Through a global map of exchange stands, the organization helps communities build gardens and a food sovereignty network.Key TopicsGarden Exchange Stands nonprofitCommunity-based seed and plant sharingFood sovereignty and local food systemsNeighborhood garden exchange networksPollinator-friendly gardeningPermaculture-inspired community designSeed saving and seed stewardshipFree garden exchange stands and seed librariesBuilding resilient neighborhood communitiesGardening as a tool for connectionVolunteer-driven nonprofit organizingSharing herbs, cuttings, tools, and garden suppliesInteractive global garden stand mappingSustainable living and wildlife habitat gardeningKey Questions AnsweredWhat is a Garden Exchange Stand?A Garden Exchange Stand is a neighborhood sharing station where people exchange seeds, plants, herbs, gardening tools, books, and other garden-related items for free. Some are permanent outdoor structures while others are portable or seasonal.How did Garden Exchange Stands begin?The project started organically when DePhane hosted seed and plant exchanges at her home. Leftover plants and supplies were placed near a neighborhood bench for others to take, eventually evolving into a larger community-driven nonprofit network.Why are garden exchange networks important?They strengthen local communities, encourage food production, reduce waste, support pollinators, and create opportunities for neighbors to connect through gardening and shared resources.How do people find exchange stands?Garden Exchange Stands uses an interactive online map where users can search by city, stand name, or location to find participating stands and seed-sharing sites.What kinds of items are exchanged?Participants share seeds, seedlings, herbs, cuttings, tools, gardening books, shade cloth, baskets, aprons, painted rocks, and seasonal harvests.Can people participate even if they live in an HOA?Yes. Many participants create small movable stands or seed libraries that fit HOA guidelines while still serving their local community.How does the organization support community resilience?The network encourages local food production, seed saving, pollinator habitat creation, and community cooperation — all key components of resilient local food systems.What role do volunteers play in the organization?The entire network is volunteer-powered. Volunteers help moderate groups, maintain stands, move plants between locations, host events, and support educational workshops.Why are herbs recommended for beginner gardeners?Herbs are inexpensive to grow, easy to maintain, highly productive, and useful for cooking and wellness. DePhane especially recommends rosemary and basil for beginners.What larger mission drives the organization?The mission centers on reconnecting people through gardening, sharing abundance, supporting wildlife, and rebuilding a culture of local food production and neighbor-to-neighbor generosity.Episode HighlightsDePhane shares how her family’s gardening traditions inspired the creation of Garden Exchange Stands.The organization now supports hundreds of exchange locations throughout Arizona and additional stands across the United States.Garden stands operate similarly to Little Free Libraries, but for seeds, plants, and gardening supplies.Community members help maintain stands by watering plants, tidying displays, and redistributing excess supplies.The nonprofit promotes pollinator habitats alongside food production and seed saving.A Mother Earth News feature helped expand awareness of the movement into other states.Volunteers regularly transport plants and cuttings between cities to support gardeners across the region.DePhane explains how gardening creates lasting emotional connections between neighbors and communities.ResourcesGarden Exchange StandsArizona Garden Exchange Stands Facebook GroupSeed Library NetworkBook Recommendation — The Complete Book of Herbs by Leslie BremnessVisit www.urbanfarm.org/GardenExhangeStands for the show notes on this episode, and access to our full podcast library!

Transcribe →982: Local Seeds Build Global Food Security
May 100:47:22Tap to summarizeWith Host Greg Peterson and Guests Bill McDorman and Rebecca NewburnFind our monthly Seed Chat at SeedChat.orgIn This Podcast: This episode of Seed Chat explores the future of seed sovereignty through two connected lenses: grassroots seed libraries and the global seed banking system. Greg Peterson is joined by Bill McDorman and special guest Rebecca Newburn to examine how communities can steward seeds locally while industrial institutions struggle to preserve crop diversity at scale. Rebecca shares how the seed library movement has grown into a global network and why the next challenge is helping communities “close the loop” by saving and returning seeds. Bill then zooms out to explain the history, promise, and limitations of international seed banks—and why local seed stewardship may be our most resilient path forward. Key TopicsSeed Library NetworkCommunity seed librariesSeed saving educationCGIAR international gene banksGlobal Crop Diversity TrustSvalbard Global Seed VaultGRIN (Genetic Resources Information Network)Regional seed co-opsClimate adaptation through seed diversitySnake River Seed CooperativeUtopian Seed Project Key Questions AnsweredHow do seed libraries actually strengthen local food systems?Seed libraries give communities free access to seeds while rebuilding the habit of growing, saving, and sharing locally adapted crops. Their long-term value is not just seed distribution, it is creating local resilience through community stewardship and regional seed knowledge. What makes a seed library successful over time?The strongest seed libraries are sustained by committed people, clear systems, and community participation. Whether run by one passionate organizer or a collective, successful libraries create pathways for education, local seed donations, and long-term stewardship. What does it mean to “close the loop” in a seed library?It means moving beyond simply borrowing and planting seeds. A resilient seed library teaches people how to save seeds, clean them, label them, and return them so the system becomes regenerative instead of extractive. What is CGIAR and why does it matter?CGIAR is a global agricultural research network that manages 11 major international gene banks holding hundreds of thousands of seed accessions. These collections preserve crop diversity and serve as a global backup for agriculture, but they are increasingly underfunded and difficult to access. Why are global seed banks under pressure?Major seed banks face chronic funding shortages, institutional bottlenecks, and climate-related risks. Even the world’s largest backup systems, including Svalbard, are vulnerable to warming temperatures, infrastructure strain, and political instability. Why is local seed saving becoming more urgent?As climate disruption, fertilizer shortages, and industrial fragility intensify, communities will need crops adapted to local conditions. Local seed saving builds food security, preserves biodiversity, and gives communities direct control over future growing conditions. What role do regional seed companies and seed co-ops play?Regional seed companies and co-ops bridge the gap between grassroots seed libraries and commercial distribution. They grow regionally adapted seed at scale, distribute locally, and help create more durable seed infrastructure. Why does Bill argue that “nobody’s coming”?Bill’s central argument is that communities cannot rely solely on governments, institutions, or global systems to protect seed diversity. The responsibility for preserving and adapting seeds increasingly falls to local growers, seed savers, and regional networks. Episode HighlightsRebecca Newburn explains how seed libraries have evolved from a novel idea into a global movement with thousands of community-led seed libraries. Seed libraries succeed when they move beyond free seed distribution and teach people how to save and return seeds. Rebecca shares new downloadable “zines” designed to help gardeners plant, save, and return seeds with clear instructions. Bill outlines how CGIAR’s global gene banks were built to preserve crop diversity but now struggle with access, staffing, and long-term funding. The Global Crop Diversity Trust still lacks the endowment needed to sustainably maintain major international seed collections. Bill argues that climate resilience depends on getting seed diversity back into the hands of growers, not just preserving it in vaults. Regional seed banks and co-ops may offer a more resilient model than centralized institutions alone. Collaboration—not competition—is framed as the cultural shift needed to rebuild seed resilience at scale.

Transcribe →981: Who Owns the World's Seeds with Bill McDorman
Apr 2400:35:35Tap to summarizeThis Seed Chat explores the growing consolidation of global seed ownership and the implications of patenting life. Farmer Greg and Bill McDorman dive into the history of seed patent law, the rise of corporate control, and the tension between industrial agriculture and traditional seed saving. They highlight global efforts, especially in Europe, to resist seed patents and protect biodiversity. The episode emphasizes seed saving as both a practical skill and a powerful act of resilience and autonomy.Key TopicsCorporate consolidation of global seed ownershipSeed patenting and intellectual property rightsSupreme Court case Diamond v. Chakrabarty (1980)Plant Variety Protection Act (PVPA)Utility patents vs. plant breeder protectionsEuropean coalition: No Patents on SeedsRole of NGOs and international advocacyOpen Source Seed Initiative (OSSI)Center for Food Safety legal effortsETC Group and global seed policy researchOrganic Seed Alliance publicationsSeed saving as resistance and resilienceGenetic diversity and climate adaptationIndustrial agriculture vs. small-scale seed savingKey Questions AnsweredWho controls the world’s seeds?A small number of multinational corporations dominate the global seed market, controlling a significant percentage of commercial seed distribution. This concentration is driven by mergers, acquisitions, and patent protections that favor industrial agriculture.How did seed patenting become legal?The 1980 Supreme Court ruling in Diamond v. Chakrabarty opened the door for patenting living organisms. This decision enabled utility patents on seeds, allowing companies to claim ownership over genetically modified—and later even conventionally bred—plants.What was the original compromise to protect seed breeders?The Plant Variety Protection Act (PVPA) provided a 20-year protection period for breeders while still allowing farmers to save seeds and researchers to use protected varieties. This balance has been eroded by utility patents.Why are seed patents controversial?Seed patents restrict farmers from saving seeds and limit other breeders from using patented genetics. This undermines traditional agricultural practices and reduces biodiversity.What is being done globally to resist seed patents?Organizations like No Patents on Seeds in Europe mobilize public campaigns, monitor patent filings, and challenge approvals. Coalitions of NGOs are working to influence policy and raise awareness.What is the Open Source Seed Initiative?OSSI is a movement that protects seeds from patenting by creating a legal framework that ensures varieties remain freely available for use, breeding, and saving.Why is seed saving important?Seed saving preserves genetic diversity, strengthens local food systems, and gives growers autonomy. It’s a foundational practice that has sustained agriculture for over 10,000 years.Is seed saving difficult?No—contrary to common belief, seed saving is simple at a small scale. The complexity often associated with it comes from industrial agriculture requirements, not backyard or community gardening.Episode HighlightsGlobal seed ownership is increasingly concentrated among a few corporations.The 1980 Supreme Court ruling enabled the patenting of life forms.The PVPA once balanced breeder rights with farmer freedoms.Utility patents now restrict both seed saving and research.European NGOs have mobilized hundreds of thousands against seed patents.Seed saving is accessible, resilient, and historically proven.Genetic diversity is critical for adapting to climate change.Local seed saving builds community and food sovereignty.Calls to Action & ResourcesJoin Live Seed Chats - https://seedchat.orgLearn about seed freedom advocacy - https://www.no-patents-on-seeds.orgExplore open-source seeds - https://osseeds.orgSupport legal advocacy - https://www.centerforfoodsafety.orgNo Patents On Seeds - https://www.no-patents-on-seeds.org/enOrganic Seed Alliance - https://seedalliance.org/A Guide to Seed Intellectual Property Rights - https://seedalliance.org/publications/a-guide-to-seed-intellectual-property-rights/Penn Parmenter - https://www.pennandcordsgarden.com/Seed The Untold Story - https://www.seedthemovie.comEmail Bill at elmoclap@proton.me CanadaNational Farmers Union - Save Our Seed - https://www.nfu.ca/learn/save-our-seed/Seed Change - https://weseedchange.org/etc Group - Research global seed policy — https://www.etcgroup.orgVisit UrbanFarm.org/981 for the show notes and links on this episode!

Transcribe →980: Free Water From You Home with Brad Lancaster
Apr 1700:36:50Tap to summarizeA Rosie On The House ReplayThis episode explores practical, low-cost strategies for reusing household gray water to irrigate landscapes. Brad Lancaster shares decades of experience designing regenerative water systems in dryland environments, emphasizing simple gravity-fed solutions over complex infrastructure. The conversation highlights how homeowners can dramatically reduce water use by “stacking functions” and capturing water already on-site. By pairing gray water with rainwater harvesting, households can meet most or all of their irrigation needs. Brad Lancaster runs a successful permaculture consulting design and education business in Tucson, Arizona. He's focused on integrated and sustainable approaches to landscape design, planning and living. Growing up in a dryland environment, water harvesting has long been one of his specialties and a true passion. He's the author of the Permaculture Bible for Water Harvesting, Rainwater Harvesting for Drylands and Beyond, Volumes One and Two. And he has just released new color versions, revised and expanded of both of them.Key TopicsGray water (definition and household sources)Difference between gray water and black waterBrad Lancaster (water harvesting expert)Rainwater harvesting systemsGravity-fed irrigation designSoil as a living filtration systemMulch basins and infiltration strategiesLaundry-to-landscape systemsOutdoor shower gray water reuseWater conservation in dryland climatesArizona gray water regulations (13 guidelines)Soap and detergent impacts (salt vs liquid)Planting water before plants (design philosophy)Evapotranspiration and passive coolingKey Questions AnsweredWhat is gray water and how much of household water does it represent?Gray water is lightly used water from showers, sinks, bathtubs, and washing machines. It represents a significant portion of household water use—nearly equal to outdoor irrigation demand—making it a major opportunity for reuse.Is gray water safe to use in the landscape?Yes, when basic guidelines are followed. Avoid toxins, prevent pooling, and distribute water across multiple areas. Soil biology naturally filters the water, making it safe for fruit trees and many landscape plants.How can homeowners start using gray water cheaply and easily?Simple systems like redirecting a washing machine hose or using an outdoor shower can send water directly to plants using gravity. No pumps, tanks, or complex filtration systems are needed.What soaps and products should be used with gray water systems?Liquid soaps are preferred over powdered detergents because they contain fewer salt-based fillers. Avoid chlorine bleach and opt for hydrogen peroxide alternatives to protect soil health.Why shouldn’t gray water be stored in tanks?Stored gray water quickly turns septic due to organic matter, creating odor and health issues. It’s best used immediately by directing it into soil systems.How does combining gray water and rainwater maximize impact?Together, they can meet nearly all irrigation needs for a landscape, especially with low-water-use plants. This reduces reliance on municipal water and increases resilience.What does “plant the water first” mean?Design the landscape to capture and infiltrate water using basins and contours before planting. This ensures plants receive consistent moisture naturally.Where should plants be placed in a water-harvesting landscape?Higher water-use plants should be placed near water sources like roofs or gray water outlets. Trees should be positioned for shade and cooling benefits, especially on east and west sides of buildings.Episode HighlightsGray water is “perennial water”—it flows daily as long as you live in your homeYou’ve already paid for this water—reuse it instead of sending it to the sewerA simple laundry system can irrigate multiple trees by rotating a drain hoseSoil acts as a living sponge and filter, outperforming mechanical systemsOutdoor showers can double as irrigation systems and cooling zones for animalsAvoid overcomplication—gravity systems are cheaper, more reliable, and effectiveCapturing both rainwater and gray water can eliminate most irrigation needsWater harvesting landscapes create cooler microclimates and support biodiversityCalls to Action & ResourcesBrad Lancaster Resources — https://www.harvestingrainwater.comYouTube Channel — Search “Brad Lancaster water harvesting”Books — Rainwater Harvesting for Drylands and Beyond (Volumes 1 & 2)Visit www.UrbanFarm.org/980 for the show notes and links on this episode!Need a little bit of advice or just a feedback on your design for your yard or garden?The Urban Farm Team is offering consults over the phone or zoom.

Transcribe →979: From Forest to Farm: Chris Parker’s Fungal Innovations
Apr 1000:40:07Tap to summarizeIn this Episode Christopher Parker shares his lifelong journey into mycology, rooted in growing up in the forests of Western North Carolina and decades of hands-on experience. He explains how fungi underpins life on Earth, drives soil fertility, and plays a critical role in regenerative agriculture. The conversation explores low-tech mushroom cultivation, indigenous ecological knowledge, and how working with fungi can create resilient, localized food systems. Christopher also highlights practical ways to grow mushrooms, restore ecosystems, and build livelihoods rooted in land stewardship.Our Guest: Christopher Parker is a member of the Eastern Band of Cherokee Indians, he is a farmer, educator, and myco-culture keeper with over 30 years of experience in Indigenous regenerative agriculture and mushroom cultivation. He co-founded The Forest Farmacy, an Indigenous-led mushroom school rooted in the Cherokee homeland of Western North Carolina. Chris teaches applied eco-mycology—weaving traditional forest-tending knowledge with modern cultivation science to heal ecosystems and strengthen food sovereignty. His work centers on low-tech, scalable cultivation that transforms farm and forest byproducts into gourmet and medicinal mushrooms. Through his teaching and mentorship, he helps farmers and land stewards create ecologically sound, culturally rooted, and economically resilient livelihoods.Key Topics & EntitiesChristopher ParkerIndigenous regenerative agricultureMushroom cultivation (low-tech and scalable)Mycology and soil microbiologyMycorrhizal fungi (ecto & endo)Food sovereignty and local food systemsForest farming and ecosystem restorationTrichoderma and soil regenerationKorean Natural Farming (KNF)Biochar and microbial inoculationMushroom cultivation on logs and sawdustThe Forest FarmacyThe Mycelial Healer (book)Radical Mycology (book by Peter McCoy)Key Questions AnsweredWhy does fungi matter in soil and regenerative agriculture?Fungi act as the “underground economy,” moving nutrients, water, and minerals between soil and plants. They unlock nutrients already present in the soil, reducing or eliminating the need for external fertilizers.Can healthy soil eliminate the need for fertilizers?Yes. When fungal and microbial life is balanced, natural processes provide nutrients to plants, dramatically reducing inputs and allowing nature to do the heavy lifting.How do mushrooms actually grow and function?The visible mushroom is only the fruiting body. Most of the organism exists as mycelium within logs or soil, breaking down organic matter and cycling nutrients.What is a simple way to start growing mushrooms?Low-tech methods like inoculating logs, pasteurizing straw, or using simple heat sources can produce mushrooms without expensive equipment.How can mushroom cultivation support regenerative farming?Spent mushroom substrates and even contaminated batches can be repurposed to build soil biology, suppress pathogens, and enhance fertility.What role does observation play in successful growing?Careful observation of natural systems—like how fungi interact with insects, trees, and decay—reveals cultivation insights that can outperform conventional methods.What are common failures in mushroom cultivation?Certain species like maitake and chicken of the woods are difficult to grow on logs using standard methods. Understanding their natural ecology can unlock success.How can farmers integrate fungi into their systems?By using local fungi, building soil biology, and incorporating techniques like KNF and biochar inoculation, farmers can regenerate land while producing food.Episode HighlightsFungi and bacteria underpin all life on EarthMushrooms are just the “fruit”—most life is hidden as myceliumHealthy soil biology can eliminate fertilizer needsLow-tech mushroom growing is accessible to anyoneContaminated mushroom bags can regenerate soil via biocharObservation of nature led to breakthroughs in cultivation methodsIndigenous knowledge and modern science can work togetherStart small, learn deeply, and scale graduallyCalls to Action & ResourcesThe Forest Farmacy — https://theforestfarmacy.comChristopher's Book: The Mycelial Healer — Available via Chelsea Green PublishingCourse — Year-long mushroom cultivation program HEREChristophers Book Recommendation - Paul Stamets, Growing Gourmet Medicinal Mushrooms and Radical Mycology by Peter McCoyShow Notes — https://urbanfarm.org/forestfarmacyVisit www.urbanfarm.org/ForestFarmacy for the show notes on this episode, and access to our full podcast library!

Transcribe →978: Building the largest worm farm in the U.S. with Zach Brooks
Apr 300:30:54Tap to summarizeIn this Episode Zach Brooks shares how he transformed a barren cotton field into the thriving Arizona Worm Farm which is now one of the largest worm composting operations in the U.S. What began as a personal experiment in sustainability evolved into a regenerative, off-grid-inspired ecosystem that converts waste into soil, food, and community education. Zach explains how worms, compost, and black soldier flies work together to rebuild soil and produce nutrient-dense food. The conversation highlights practical, scalable solutions for local food systems using simple, accessible technologies.Our Guest: Zach semi-retired from healthcare management at the age of 42 when his consulting company went public, and when his first of three grandchildren were born, he went back to Arizona State University to get a second master's degree in sustainability. Frustrated that most causes of climate change were not only fixable, but fixable with off the shelf practices and technology, Zach set out to prove that an off-grid lifestyle could be every bit as comfortable as a wasteful lifestyle and have a positive impact on the environment. And the most exciting thing...Zach has now built Arizona Worm Farm into one of the largest most successful worm farms in the United States. What is the Arizona Worm Farm?A regenerative, working farm designed to turn food waste into compost, soil fertility, and food production while educating the community on sustainable gardening practices.How did Zach Brooks get started in worm farming?After a career in healthcare, Zach pursued a sustainability degree and became motivated to address climate challenges using practical, existing solutions. He started by rebuilding dead soil using worms.How large has the operation become?The farm produces over 4.5 million worms annually, supports thousands of customers, and manages millions more worms dedicated to compost production.What role do worms play in soil regeneration?Worms convert organic matter into nutrient-rich castings filled with beneficial microbes that improve soil health, fertility, and plant growth.What do the worms eat at scale?Primarily pre-composted organic waste, including horse manure, landscape waste, and pre-consumer food scraps from caterers and food processors.Why is local composting important?Fresh, local compost contains active microbial life and reduces landfill waste, creating a closed-loop system that supports local food production.What are black soldier flies and why are they important?They are composting insects whose larvae consume waste rapidly and convert it into high-quality protein for animals, offering a sustainable alternative feed source.What makes Arizona Worm Farm a “one-stop shop” for gardeners?It combines education, compost, worms, plant starts, and regenerative techniques to help people successfully grow food at home.How does the farm generate revenue beyond worms?Through classes, compost products, plant starts, and value-added inputs like worm tea and insect-based fertilizers.What is the long-term vision behind the farm?To demonstrate that regenerative, self-sustaining systems can support communities using simple inputs like sunlight, water, and organic waste.Episode HighlightsBuilt from a dead cotton field into a regenerative ecosystemScaled from 400,000 to 4.5 million worms annuallyProduces 80,000 worms per week through controlled breedingDiverts large volumes of food waste from landfillsIntegrates composting, aquaponics, and food forestsHosts highly sought-after, sold-out educational classesProduces 400–800 lbs of insect protein weekly via black soldier fliesDemonstrates year-round food production in a desert climateKey TopicsArizona Worm FarmZach BrooksWorm composting (vermiculture)Black soldier fly larvae systemsRegenerative agricultureSoil microbiology & soil food webComposting systems (hot compost + worm compost)Food waste diversionOff-grid living systemsAquaponics integrationSeasonal planting strategiesUrban farming education programsLocal food systems & backyard gardeningSustainable protein production (insects)ResourcesArizona Worm Farm — https://arizonawormfarm.comShow Notes — https://urbanfarm.org/azWormFarmClasses & Workshops — Available via website mailing listSelf-Guided Farm Tours — Visit in South PhoenixVisit www.urbanfarm.org/AZWormFarm for the show notes on this episode, and access to our full podcast library!
