When the 44 clans of Namblong gathered to defend their ancestral forests in Indonesian Papua, they weren’t just saying no to oil palm developers—they were rebuilding a system of governance that had been dismantled for decades. Their territory, spanning 52,000 hectares (128,500 acres) in the heart of West Papua, remains more than 80% forested—not because of a conservation project, but because of a quiet revolution in self-determination. For years, deforestation has been treated as the disease, measured in satellite pixels and carbon stocks. But in Namblong, they’ve come to see it differently: deforestation is the symptom. The real illness is de-governance—the systematic erosion of Indigenous authority over land, resources, and future. Across Indonesia, forests vanish not because trees are inherently vulnerable, but because decisions about them are made far from the people who’ve lived with them for generations. Concessions are granted, projects launched, and billions spent—all too often bypassing the very institutions that have sustained these ecosystems for centuries. In Namblong, the response wasn’t another top-down program. It was the creation of BUMMA (Badan Usaha Milik Masyarakat Adat), an Indigenous Peoples’ Corporation legally structured as a limited liability company but rooted in customary law. Owned collectively by the Kanum tribe, with nontransferable shares and leadership drawn from ancestral governance structures, BUMMA is not just an economic vehicle—it’s a vessel of sovereignty. It allows the community to engage with markets, negotiate with governments, and generate income from sustainable ventures like non-timber forest products, all without surrendering control or fragmenting land ownership. The foundation was laid by revitalizing the tribal council, strengthening customary deliberation (menoken), and re-rooting identity in territory (membumi). From there, BUMMA Namblong emerged as a new kind of institution—one that governs both economy and ecology. Already, the model is spreading. Other Kanum communities, mapping over 360,000 hectares in Indonesia and nearly 600,000 in Papua New Guinea, are preparing to establish their own BUMMAs. This isn’t about protecting forests as distant objects; it’s about recognizing Indigenous peoples not as beneficiaries, but as decision-makers. When governance is restored, forests endure. And when communities hold the pen, the future is written differently.
