Blue Builders is a podcast sharing the stories of people working to conserve and restore our ocean ecosystems. As a new series from the Nature Builders Podcasts , Blue Builders explores the journeys of individuals who have committed their lives and careers to marine conservation: from grassroots activists and scientists to entrepreneurs, policymakers, and funders. Through in-depth, unscripted conversations, we dive into what drives lasting commitment to nature, what actually works in the field, and how diverse strategies can come together to address the climate and biodiversity crises. Blue Builders strips away idealism to reveal the practical mechanics of marine restoration. For listeners seeking authentic, boots-in-the-sand perspectives on ocean conservation, these conversations offer insight into how diverse approaches collectively build resilience in our threatened blue world. I hope that their stories inspire you as much as they inspired me! Hosted on Acast. See acast.com/privacy for more information.

For those who know me, my lifelong passion for the ocean and for sharks in particular can sometimes be let's say... overwhelming๐. So, this conversation with Stefanie Brendl meant a lot to me. In this episode, she walks us through how Shark Allies pioneered a trade-based approach to shark conservation, starting with the landmark Hawaii shark fin trade ban in 2010 and sparking a global wave of legislation that followed. We discussed: โ What it feels like to be surrounded by tiger sharks in the open ocean โ How the image of sharks in the media has evolved although protection still lags behind โ Why blaming Asian demand is just the tip of the iceberg with the whole world supplying shark fins and pointing fingers at China โ Why the EU still permits shark fin trade in 2026 and supplies 40% of the Asian demand and what Shark Allies do about it ๐ฃ๏ธ ""The whole world is happily supplying shark fins and then pointing at Asia saying, 'You guys are the bad guys.'" A huge thank you to Stefanie for joining us and for fighting every single day for stronger shark protection worldwide. This episode was special. ๐ The fight isn't over.

I really loved our last conversation with Will Gertler , CEO of Kumbatia Seafood . Will and his team are striving to demonstrate that market-based conservation solutions can actually work in the field. In Blue Builders' last episode, Will explains in detail how he built Kumbatia Seafood training artisanal fishers and connecting them to international premium markets to boost their revenue while improving the sustainability of their fishing practices. ๐ช๐ฒ ๐ฑ๐ถ๐๐ฐ๐๐๐๐ฒ๐ฑ: โ Why traditional conservation models can sometimes fail fishing communities and how financial incentives can change the game โ The challenge of building an entire value chain from scratch in Kenyan remote coastal areas: from off-grid cold storage to FDA-certified processing โ Finding the subtle balance between profitability and impact measurement as an impact venture โ What is at stake in the Western Indian Ocean in terms of industrial fishing ๐ฃ๏ธ "๐๐ง ๐บ๐ฐ๐ถ ๐ง๐ช๐ด๐ฉ ๐ธ๐ช๐ต๐ฉ ๐๐ถ๐ฎ๐ฃ๐ข๐ต๐ช๐ข, ๐ธ๐ฆ ๐ธ๐ช๐ญ๐ญ ๐ข๐ด๐ฌ ๐บ๐ฐ๐ถ ๐ต๐ฐ ๐ง๐ช๐ด๐ฉ ๐ณ๐ฆ๐ด๐ฑ๐ฐ๐ฏ๐ด๐ช๐ฃ๐ญ๐บ, ๐ฃ๐ถ๐ต ๐บ๐ฐ๐ถ'๐ญ๐ญ ๐ฃ๐ฆ ๐ณ๐ฆ๐ธ๐ข๐ณ๐ฅ๐ฆ๐ฅ ๐ง๐ช๐ฏ๐ข๐ฏ๐ค๐ช๐ข๐ญ๐ญ๐บ ๐ง๐ฐ๐ณ ๐ฅ๐ฐ๐ช๐ฏ๐จ ๐ดo." With 60% of coastal Kenya living in poverty, marine conservation often comes at the expense of economic livelihoods. But what if access to premium markets could drive both income growth AND marine ecosystem recovery? #BlueBuilders #MarketBasedConservation #SustainableSeafood #ArtisanalFisheries #BlueEconomy #ImpactEntrepreneurship #MarineConservation #EastAfrica #SocialEnterprise #OceanSolutions #CommunityEmpowerment Hosted on Acast.

๐๏ธ ๐๐ฝ๐ถ๐๐ผ๐ฑ๐ฒ #๐ฑ ๐ผ๐ณ ๐๐น๐๐ฒ ๐๐๐ถ๐น๐ฑ๐ฒ๐ฟ๐ ๐ข๐๐ ๐ก๐ผ๐! ๐ฑ๐ At UNOC3 back in June, momentum toward protecting marine ecosystems gained ground with global marine protected area coverage rising from 8% to 10% as countries like Tanzania, Colombia, or French Polynesia announced new MPAs. But as these numbers grow, a fundamental question emerges: how effective are Marine Protected Areas in actually protecting our oceans? We're addressing this concern head-on with this 5th episode of Blue Builders in which we speak with Lance Morgan (President) and Sarah O. Hameed (Director of Blue Parks) from the Marine Conservation Institute who have been advocates for effective marine protection from the early days. ๐ช๐ฒ ๐ป๐ผ๐๐ฎ๐ฏ๐น๐ ๐ฑ๐ถ๐๐ฒ ๐ถ๐ป๐๐ผ: โ The gap between political announcements and ocean reality - why governments love MPAs that don't actually protect โ Why reaching 30% ocean protection by 2030 requires authentic community-led engagement โ The Cabo Pulmo transformation - how community leadership turned a depleted ecosystem into one with 400% biomass increase โ My 7-year-old burning question: did Lance really see the Titanic during his submarine missions in the deep? Lance and Sarah's 30 years of experience shows that when MPAs are designed with local leadership, they don't just preserve biodiversity - they enhance fishing opportunities outside park boundaries and create sustainable livelihoods.

๐๐ ๐In this new episode of the Blue Builders Podcast , I sit down with Markus Knigge , who shares his insights from years of working in conservation funding and project implementation across multiple continents. This conversation explores the delicate balance between challenges and hope in environmental conservation work - from witnessing climate change impacts firsthand to seeing the transformative power of well-directed funding and strong partnerships. We notably discussed: โ How global ocean commitments translate to real action on the ground โ Why funding only works with the right local partners to drive change โ What actually makes Marine Protected Areas effective, not just lines on a map โ Key expectations for the upcoming UN Ocean Conference in France โ Honest assessment of which local conservation successes can truly scale Markus's perspective on viewing conservation like a chess board - where every organization is just one piece in a larger strategy - offers a compelling framework for Hosted on Acast.

In this first episode of Blue Builders , we sit down with Tom Hickey , Project Director at The Pew Charitable Trusts , to explore the vital role of coastal wetlands in ocean conservation and climate action. Tom shares his personal journey โ from summers spent fishing off the coast of Cornwall to leading global efforts to integrate mangroves, seagrasses, and salt marshes into national climate strategies. We dive into how these ecosystems serve as powerful tools for both carbon mitigation and community resilience, and how countries can include them in their climate pledges through the Paris Agreement framework. Throughout the conversation, we explore: Why blue carbon is a useful policy tool, but not the whole story How local partnerships, community engagement, and language shape effective conservation What it takes to map, manage, and restore ecosystems across very different national contexts The challenge of scaling conservation solutions without losing local nuance This episode is a deep dive into the complexity โ and promise โ of coastal conservation. Itโs for anyone interested in how nature-based solutions are designed, funded, and implemented at scale. Hosted on Acast. See acast.com/privacy for more information.
