Model & Strategy

GreenWave is supporting a new generation of restorative ocean farmers and building the foundation for a new blue-green ocean economy that creates jobs, mitigates climate change and grows healthy food for local communities. Their 3D Ocean Farming system, which won the 2015 Buckminster Fuller Challenge, grows a mix of native seaweeds and shellfish that require zero inputs – making it the most sustainable form of food production on the planet – and simultaneously sequesters carbon and rebuilds marine ecosystems. Since their farms sit below the surface and leverage the entire water column, they produce high yields with minimal aesthetic impact and a small footprint. They create communal, not privatized, spaces by welcoming residents to boat or fish on our farms. Their crops are used as food, fertilizer, animal feed, biofuel and more. This farming model also has a low barrier to entry: anyone with 10 acres, a boat and $20,000 can be up and running within one year.

GreenWave was founded in 2014 to replicate this model. They’re laying the foundation for a just, restorative and resilient ocean economy that meets the needs of both people and the planet. They work in three areas: farmer training, policy development, and R&D. Their training program provides new ocean farmers with permitting support, hands-on technical assistance, donated Patagonia gear, free seed, small startup grants, and introductions to guaranteed buyers. Their policy and R&D programs are developed in partnership with a range of private and public institutions. GreenWave believes this is the first opportunity in generations to “do food right” by embedding justice, equality and climate mitigation into the DNA of the new ocean economy. GreenWave views our oceans as a blank slate, allowing us to take the lessons learned from the missteps of industrial agriculture and aquaculture, and build a system from the bottom up that ensures we can all make a living on a living planet.

Meet Bren Smith and Emily Stengel

Bren Smith is the Executive Director and Co-Founder of GreenWave, and the owner of Thimble Island Ocean Farm. A lifelong commercial fisherman since the age of 14, Bren pioneered the development of restorative 3D Ocean Farming, which is designed to restore ocean ecosystems, mitigate climate change, and create blue-green jobs for fishers and others — while ensuring healthy, local food for communities. Bren’s work as a 3D Ocean Farmer has been profiled by CNN, Google Food, The New Yorker, Bon Appetit, and others. His writing has appeared in the New York Times and National Geographic. In 2013, Smith was chosen as one of six “Ocean Heroes” by Oceana and Future of Fish’s “Ocean Entrepreneur” of the year. He is an Ashoka and Echoing Green Fellow.

Emily Stengel is the Deputy Director and Co-Founder of GreenWave. With a background in food industry management and agricultural research, Emily brings experience with and knowledge of the struggles faced by land-based producers. She’s committed to bringing lessons learned from land to the creation of a new blue-green economy, supporting sustainable livelihoods on the water and making the sure the barriers to entry for new restorative ocean farmers are low. Emily has an M.S. in Community Development and Applied Economics from the University of Vermont.

IMPACT

GreenWave builds and supports restorative GreenWave ‘Reefs’ around the US and abroad. Each Reef is composed of 25-50 3D Ocean Farms, clustered around a seafood hub and hatchery, and surrounded by a ring of institutional buyers and entrepreneurs.

GreenWave is currently building the New England Reef: they’ve trained 12 new farmers across 4 states, successfully operated the largest seaweed hatchery network in the US, and connected their farmers with buyers.

GreenWave farms are currently operating in 4 states. They aim to have farms in 8 states by 2020.

A 10-acre restorative ocean farm has the potential to absorb up to 7,000lbs of Carbon and 1,536lbs of Nitrogen per year.
