A research team by Prof. Ezri Tarazi as part of the Design-Tech Lab at the Technion – Israel Institute of Technology recently conducted a field project on Beqa Island, Fiji, aimed at restoring coral reefs damaged by climate change. The initiative was carried out in collaboration with marine biologists from Bar-Ilan University, led by Prof. Oren Levy, and Blue Ocean, an American NGO operating in Fiji on sustainability and social impact projects.
This innovative project demonstrates how technology, design, and local knowledge can be combined to create effective, sustainable coral reef restoration solutions.
Ocean warming, human activities, and other environmental stressors have led to global coral reef decline. According to the International Union for Conservation of Nature (IUCN), approximately 44% of reef-building corals are at risk of extinction. Beyond their ecological significance, coral reefs provide food sources, coastal protection, and carbon absorption. The economic activities related to them – including tourism and fishing – are estimated to generate tens of billions of dollars annually.
One innovative approach to reef restoration has been developed and implemented at the Design-Tech Lab at the Technion. The team there has designed a new 3D-printing technology using natural clay to create structures that support coral growth and reef regeneration. The use of 3D-printed ceramic components allows for the creation of complex, biologically tailored structures that enhance reef restoration efforts.
As part of their visit to Fiji, the group carried out two projects: installing an artificial reef 3D-printed at the Technion from ceramic clay and installing another artificial reef co-designed with a local community living near the coral reef. The project was led by doctoral student Oren Arbel, a ceramic designer researching participatory design. Over the course of a week, dozens of reef units were produced with the help of the local community using clay extrusion techniques and locally available firing methods.
