Haburas is actively involved in environmental education and advocacy. Since Timor-Leste’s independence Haburas tackled a number of high-priority environmental initiatives. Among them was protecting Lake Iralalaru in the eastern part of the country, a culturally significant wetlands area that was threatened by a proposed hydropower station and plans to pump the lake for irrigating sugarcane plantations. Haburas pushed for further environmental studies of the ecosystem and of the impact on local communities before any development moved forward.

Haburas also supports community reforestation and watershed management programs to reduce forest and land degradation. Guiding these environmental efforts was the cultural revitalization of Tara Bandu, This indigenous legal framework empowers communities to apply ancestral ecological knowledge in contemporary environmental stewardship.
