bali volunteer program reef conservation founder ketut

Ketut De Sujana Mahartana – Co Founder / Local Volunteer Coordinator

Ketut is also the founder of Yayasan Widya Sari –Volunteer in Bali, an NGO that provides free education and improves the lives of children in many villages across Bali. Since his childhood growing up in Tianyar, Ketut has noticed a significant decline in fish biodiversity and reef health along the Tianyar coast. Ketut’s family has deep roots in the fishing community and co-founded this project to provide a sustainable livelihood to the people of the village. For the past 10 years, Ketut has been working to resolve the plastic pollution problem in Tianyar by teaching children about the issues, aiming to change the mindset they develop at home. There have been significant improvements with the amount of pollution along the coastline, but he understands there is still more work to be done. Ketut has developed a keen interest in scuba diving, specifically underwater photography, from photographing volunteers helping to deploy reef structures to beautiful nudibranch smaller than a grain of rice.

Zach – Co Founder / International Volunteer Coordinator

Zach, originally from England, visited Tianyar in 2016, and realised the
local marine ecosystem was in urgent need of restoration. He worked with Ketut to establish North Bali Reef Conservation in 2017, alongside his Environmental Science degree at Bournemouth University. Zach holds a
keen interest in marine ecology and conservation, and is deeply concerned about the level of plastic in the ocean around the world. His role at North  Bali Reef Conservation involves managing volunteers and working with members to the community to coordinate conservation activities. Zach previously managed a research program at North Bali Reef Conservation which was part funded by the Society of Conservation Biology. He is now a PhD student researching the ecological and socioeconomic potential of artificial reefs in Bali, and his research is funded by Earthwatch and Bournemouth University

Yowana Bhakti Segara (YBS) fishermen group

Yowana Bhakti Segara roughly translates to ‘youth who protect their oceans’. This is a local fishermen community initiative aiming to improve fishing practices sustainably and ensure that all families in the community receive the help they need. Specifically with our project, the YBS fishermen mainly help with the construction of artificial reef structures and the deployment of structures. The most hard working and dedicated members of the YBS group who help us are now employed by us. We hope that in the future we can employ all the members of this group and expand our conservation efforts with their help.
