Since 2011, thanks to the French Ministry of Foreign Affairs (France) and Research Center for Archaeology (Puslit Arkenas, Indonesia), we have developed a collaborative and interdisciplinary French-Indonesian archaeological research project in the karstic rainforest region of East Kalimantan (Mangkalihat Peninsula, Indonesia). This project entitled “Human occupation of karstic area, Rock art, and settlement history of East Kalimantan (Indonesia)”, follows our 2005–2010 works that led to the discovery of the first and most ancient prehistoric rock art of Borneo. Since 2011 we aim to determine the chronology of human occupation and its technological development in this part of Kalimantan since Late Pleistocene/early Holocene.
Our diachronic project combines archaeological surveys and excavations, ethno-linguistic investigations and anthropobiological analyses. Located in the valley of Lesan and Marang river (Berau and East Kutai district), a region containing the nearest karstic mountains to the coast of the Celebes Sea, we investigate the population dynamics between the coast and the inland karstic forest. Further researches and collaborations are planned for the 2015–2017 period.
