The Future of Seaweed Farming in America

Vaan Island, off the coast of Indian in the Gulf of Mannar, is rapidly sinking. But scientists are working to prevent that erosion by replanting seagrass, which is an important plant in a marine ecosystem. Despite fishermen pulling up the seagrass with their nets, so far, nine acres of seagrass have been rehabilitated in the area.

Canada is paving the way in marine solutions, but they didn't get there without failure first. After decades of overfishing, the country is experimenting with a sustainable commercial fishing catch-share system that has relied on quotas, leading to a full retention, fully monitored fishery.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

An AI-powered underwater sensor system developed by KMFRI and ShoShin Innovation Hub detects dangerous drops in dissolved oxygen in Lake Victoria and sends SMS alerts to fish farmers. This enabled them to move their cages in time and successfully averting a mass fish kill in February 2026 that would have threatened hundreds of tilapia cages at Dunga Beach.

Aquaponics, a soilless method of farming that combines aquaculture and hydroponic techniques, has provided an affordable and adaptable method for growing traditional cultural Mvskoke foods, such as tobacco, pumpkins, corn, pinto beans, honeysuckle, and minara. Grant funding has enabled tribal members to use aquaponic systems to produce crops and fortify food systems against climate change.

In the mid-1990s, a small fishing community in Baja California Sur stopped fishing to give their depleted reef a chance to recover. Thirty years later, Cabo Pulmo National Park stands as one of the most documented cases of marine conservation success in the world. Scientific monitoring confirmed a 463% increase in marine biomass within a decade of protection. Drawing on this evidence, marine scientists have developed the Marine Prosperity Areas (MPpAs) framework, a replicable model that integrates ecological restoration with community well-being.

Community-led urban farms in Jakarta empower residents to transform underused city spaces like alleyways and campus grounds into productive local food sources. These initiatives often blend traditional gardening with community organizing, educational outreach, and sometimes smart technology or agricultural research to improve food access, enhance green space, and foster local resilience.

Seaweed is emerging as a solution to Maine's shifting climate and economy, providing alternative industries for ocean farmers and also supporting land farmers' climate initiatives. While still in piloting stages, studies have shown up to 50 percent reductions in methane on New England cow farms that incorporate seaweed into feed.

Communities in the Sundarbans have adopted shrimp farming as a sustainable livelihood strategy; the approach has proven successful, with environmental benefits and many farmers earning a good income.

Joebliss Enterprise purchases and collects paper waste from homes, businesses, and collection agents in Abuja, Nigeria, and processes it for recycling, reducing the amount that produces methane emissions in landfills.
