Seaweed farming at Uroa, a fishermen village on Zanzibar’s center-east coast picture by Moongateclimber

Seaweed, sex and soap

the impact of the value chain in a traditional village in Zanzibar

Women in Page don’t work; they take care of their children.

Women in this traditional village in east Africa Zanzibar don’t leave the house unless they should go to a wedding, funeral or visit a relative.

But then some women became seaweed farmers…

Every day these women go to the sea.

Then they realized the value of the value chain and started creating new products from seaweed — shampoo, soap... Seaweeds per se are cheap, but the products you can make from seaweeds are valued.

Today we are leaving Thailand where most AquaTED stories take place, but seaweed production is minimal. We will listen to a BBC podcast to learn about the seaweed value chain in Zanzibar; how it seemed to improve the local economy and how climate change, world trade and globalization is threatening this fragile chain.

You are reading a short series of factual stories about the seafood production system — this is the third of four stories. I use storytelling to facilitate conversations about aquaculture, fisheries, and all the other industries along the way. If you are an educator you can use this site in blended learning — see below learning objectives, suggested activities and further reading.
