One of my favorite parts of visiting Indonesia was photographing the seaweed farmers. From what I observed, the seaweed is grown in shallow salt water, and when ready for harvest, the farmers would wade into the water, pluck the seaweed, fill large baskets and stack them on top of inner tubes for easy transport back to shore. Sometimes kayaks or canoes were used instead of inner tubes, depending on which type of seaweed was being harvested. Once back on land, the seaweed would go through various stripping, sorting, and drying processes, all done by hand. And all of which you will see in future photos.
"[Seaweed farming] has recently been thrust onto the global agenda as a coastal livelihood alternative that links economic growth both to food security and to climate change adaptation and mitigation. Seaweed, a marine algae, requires no fresh water or fertilizers to thrive, is fast-growing and nutrient-intense, and doesn't interfere with land-based systems. It has a number of end-uses, including carbon-dioxide removal via bio-sequestration."
