Nusa Lembongan, a small island southeast of Bali, is not only known for its turquoise waters and laid-back charm, but also for a time-honoured tradition that continues to shape its community—seaweed farming. While tourism has taken the spotlight in recent years, this sustainable local industry still thrives and offers a fascinating glimpse into the island’s cultural and economic roots.
A Way of Life
For many families on Nusa Lembongan, seaweed farming isn’t just a job—it’s a generational livelihood. At low tide, you’ll see rows of seaweed farms stretching across the shallow waters, with farmers tending to their crops by hand. It’s a quiet, rhythmic process, deeply connected to the tides and the cycles of the moon.
Seaweed farming on the island dates back decades. Before Lembongan became a tourist hotspot, this natural aquaculture was a primary income source, helping to support entire villages.
How It Works
The farming process begins with planting seaweed cuttings onto ropes anchored in the shallow seabed. Over the course of 35–45 days, the seaweed grows and is harvested by hand. After drying in the sun for several days, it’s sold to middlemen or processing companies and eventually used in cosmetics, food products, and pharmaceuticals around the world.
Sustainability and Culture
Unlike other forms of farming, seaweed cultivation has minimal environmental impact. It doesn’t require fertilisers, pesticides, or freshwater. In fact, seaweed absorbs carbon dioxide and promotes marine biodiversity. The practice supports eco-tourism and is often included in island tours that highlight authentic local experiences.
The farming process also provides a beautiful cultural contrast to the fast-paced tourism on the island. It’s common to see seaweed farmers working with entire families, with children playing nearby and elders tying the ropes.
Where to See It
The best spots to observe seaweed farming in Nusa Lembongan are Jungut Batu and Lembongan Village. Visit at low tide, early in the morning or late in the afternoon, to see locals out in the water. Some tour operators even offer educational walks or boat rides through the farms.
Supporting the Local Economy
While the number of seaweed farmers has declined due to tourism development, the industry still provides income and pride for many households. Buying local seaweed-based products or joining a cultural tour is a simple way to support the local economy and keep the tradition alive.
Seaweed farming in Lembongan is more than just a livelihood—it’s a living connection between the islanders and the sea. As visitors, taking the time to understand and appreciate this quiet tradition adds depth to your travel experience. It’s a reminder that beneath the picture-perfect beaches lies a rich cultural story, still unfolding with every tide.
