Palm Fronds and Stones: Creating Reefs to Heal Tunisia's Polluted Seas

Artificial reefs made from palm branches are fixed to the seabed with stones to create spaces for cuttlefish and other creatures to lay eggs. In the past, coastal farmers would throw palm fronds into the sea after harvesting dates

Tunisian environmentalists are trying to fight pollution damage along their country's Mediterranean shores by installing artificial reefs to encourage sea life.

Members of the Notre Grand Bleu organisation make the reefs from palm branches fixed to the seabed with stones to create spaces for cuttlefish and other creatures to lay eggs.

Pollution - caused by climate change, untreated sewage, plastics, fish farming and industrial discharges - has affected much of the Tunisian coast, said the organisation's president, Ahmed Souki.

However, the organisation says it cannot afford a scientific study to assess how widely pollution has killed off sea life in Tunisian waters.

It has started creating the artificial reefs off Monastir, a popular beach resort.

"We wanted to be part of the solution, by placing palm branches with stones," said Manel Ben Ismail, a director at the group.

In the past, coastal farmers would throw palm fronds into the sea after harvesting dates. On the seabed the plants fostered marine life, said Souki.

"We wanted to return to this technique," he added.

The organisation said it was too early to provide data on the success of its scheme. But video footage shows sea urchins and other creatures using the artificial reefs it has created.
