The Dayak Tomun Indigenous Community of Kubung Village is located in Delang District, Lamandau Regency, Central Kalimantan. For them, forests and land are not just open ground to stand on and live, but a cultural and spiritual cosmos. That is one of the reasons why the Dayak Tomun Indigenous Community strongly rejects the entry of Industrial Plantation Forest (HTI) and oil palm plantation companies. The Dayak Tomun Indigenous Community has long made efforts to obtain official recognition from the government for their customary territory.

To strengthen the efforts to submit protection and recognition of Indigenous Peoples to the Lamandau District Government, with the support of Direct Funding from the Nusantara Fund, the Dayak Tomun Indigenous People conducted historical and cultural tracing and documentation that included narratives of territorial boundaries and cultural heritage, including documentation of customary symbols and sacred places. This effort was strengthened by participatory mapping of managed areas and the preparation and submission of documents for protection and recognition of the Dayak Tomun Indigenous Peoples to the Lamandau District Government.

The process of tracing and documenting history and culture involves indigenous communities widely, from traditional elders to the younger generation, who actively participate in collecting data and documenting the history and boundaries of traditional territories. Mapping the area also becomes the basis for them to strengthen their claims for sustainable forest management and livelihoods.

Participatory mapping also involved Pokdarwis Ongkah, People's Organizations, and several other stakeholders, the total area of ​​customary territory mapped was 12.225 hectares. This map clearly describes its customary territory and includes various potential natural resources as well as customary symbols and important historical relics.

Activities such as area mapping, compiling village histories, and training in livelihood management provide long-term benefits that will be felt by the entire Kubung Village community. This program benefits 587 people, consisting of 244 women, 243 men, 46 young men, and 54 young women.

Recognition of customary territories provides certainty and legal protection for Indigenous Peoples to manage and protect customary territories, especially from industrial exploitation which is often the cause of deforestation and environmental damage. With the efforts to recognize customary territories, the Dayak Tomun Indigenous Peoples can manage forests and natural resources sustainably, in accordance with their traditions and cultural values.
