Another source of income for local people is seaweed-farming.
Jambiani women hold a long tradition in cultivating seaweed for export
as a raw material in the vegetarian food and health industry.
Because of the nature of the reef, about a mile out, the wave action litters the beach with seaweed at low tide.
Seaweed is taken, dried, and sold to exporters - generally making its way as a nutritional product as far away as Japan.
