Nusa Lembongan doesn’t have enough rainfall to reliably grow crops. They grow bananas for local consumption and some years the corn crop is a success. For the past 20 years, the main industry has been seaweed harvesting. It is sold to companies who use it to make an additive for ice cream.
The seaweed has a 20 day cycle from planting to harvest. Here are the baskets used to haul the baby plants which are tied to strings. They are staked into the ocean at low tide.
Here is seaweed in boats.
At low tide you can see the new plants which are tied to rope. They are staked into the ocean floor.
After harvested, the seaweed is bleached in the sun.
The islanders are very strong, able to carry heavy baskets of wet seaweed on their heads.
When it is not quite low tide you can see some of the more mature plants growing in deeper water.
