Sungai Utik is a Dayak Iban Community in Kapuas Hulu, West Kalimantan, Indonesia. The Dayak Iban People continue to practice their customary systems, including the Rumah Betang (traditional longhouse) culture, which accommodates more than 300 people. Their cultural practices of cooperation, reciprocity with nature, and sustainable use and management of resources make them an exemplary model and icon among other Indigenous Peoples. Many Indigenous leaders and others visit the community to learn how the Dayak Iban maintain and preserve their culture, traditional knowledge and protect their customary forest while maintaining strong community unity and cohesion. 

From their 214-meter longhouse, the  Sungai Utik Community has protected their 9,504-hectare customary forest against corporate interests and illegal loggers. For decades, the  Sungai Utik community has demonstrated their collective commitment and unity to defend their ancestral territories while practicing local management traditions. The Dayak Iban People in Sungai Utik have a customary spatial system of resource conservation and management guided by strict customary rules. These have been proven effective in maintaining the sustainability of the ecosystems in their territory, including forests, wetlands, and the Sungai Utik river.
