Coastal resilience is key to preserving our planet’s diversity

I've always had a deep connection to the ocean. Having grown up in several coastal areas in Europe and across Africa, I've spent significant time in and around the ocean, surfing, scuba diving, sailing, and experiencing first-hand the beauty of these vibrant communities that have lived in harmony alongside the sea. It's my upbringing that nurtured my profound curiosity about indigenous cultures and beliefs, and my resolve to safeguard these increasingly fragile environments.

That's why I've dedicated my personal time to finding opportunities to return to my early roots and reconnect with the diverse people and cultures of the world. One such experience was on a recent visit to Sumba, an island located east of Bali, Indonesia, where I had the fortunate opportunity to learn about the Sumbanese Marapu culture, whose unique way of life is at risk of disappearing. The Sumbanese are known for their distinct spiritual conception of the world, pointed-roof architecture and megalith monuments honouring their ancestors - customs and traditions unique to them alone.

The Sumbanese people are also deeply tied to the ocean. Each day, during low tide, the local Sumbanese villagers descend onto the beach to gather seagrass and crustaceans for food while their water buffalos enjoy a refreshing bath in the waves. There, where the land and sea converge, is a lifeline for generations.

In Sumba, and as I had in my childhood, I experienced a community whose survival had been interwoven with the ocean for millennia. Yet, today, their way of life is under threat due to climate change. Rising sea levels, coastal erosion, and mounting sea temperatures are endangering not only the rich cultural heritage of communities like Sumba but also their very existence.
