Our ocean ecosystem is collapsing

Seaweed and small-scale fishers are the solution

Business as usual is not an option. A rapid increase in restorative seaweed farming is needed to drive ocean and climate restoration. There are 22 million small-scale fishers that can drive this change…

Community. Commerce. Conservation. Climate.

Why should we care?

Community

Small-scale fishers provide 50% of the world’s seafood and 90% of fisheries employment. But they are marginalised by exploitative value chains that drive unsustainable fishing and deepening poverty

Conservation & Climate

The ocean provides 70% of our oxygen, 17% of animal protein, and it has buffered climate change impacts. But it is on the brink of collapse

Commerce

Seaweed is a more efficient seedstock for bioplastics and biofuels than land crops, and provides habitat for fish. But it is limited by underestimating small-scale fishers as a route to scale

Our ambition is to build Asia’s leading regenerative seaweed enterprise, benefiting the 4Cs of Communities, Commerce, Conservation and Climate.

We have a proven track record

Coast 4C is a social enterprise launched by ZSL in 2020 to drive ocean and climate restoration through inclusive value chains for regenerative seaweed and end-of-life fishing nets. Coast 4C builds on the award-winning Net-Works project co-created by ZSL and Interface which validated the inclusive value chain model in the Philippines and successfully tested replication in Cameroon and Indonesia. Take a look at one of our solutions for tackling marine plastic pollution that causes ghost fishing and how we work with responsible global markets to benefit people, planet and profit…

Our Reach and Impact

267

million metres

 of discarded fishing net diverted from the ocean and regenerated into high value carpet tiles, reducing ghost fishing

5,321

hectares

of the ocean protected in seven community-based marine protected areas that are 50 times the national average size

2,015

households

with gender equitable financial inclusion through 86 community banks in 32 villages

94

seaweed farming families

 trained in ecological seaweed farming techniques and supplying Coast 4C

1,888

hectares

 of no-take ‘replenishment’ zones in seven iMPAs, more than 20 times the national average size.

199

hectares

 of suitable habitat for ecological seaweed farming zoned within seven iMPAs: enough for 1,368 family farms
