Indonesian oil palm production has doubled in the last decade, driven by increasing consumption at national and global scales. Oil palm plantations are associated in Indonesia with increased value added and employment, but also land expansion, leading to GHG emissions and biodiversity loss. Models and scenarios are often used to investigate potential future development and options to mitigate socioeconomic and environmental trade-offs, yet no model is able to adequately cover most relevant dynamic processes across spatial scales (from global to local) and disciplines (socioeconomics vs. environmental aspects). To close this gap, this study develops a coupling method to link Indonesia-tailored versions of the GLOBIOM partial equilibrium model and the MRIO input-output model, and use it to analyze the potential future developments of Indonesian oil palm. This study shows that from 2010 to 2030, the global economic output is estimated to increase by 100.1 billion Euro. This will increase to 120.9-141.3 billion Euro due to increasing global oil palm demand, depending on the amplitude of global demand. Indonesia economic output will expand from 38.2 billion Euro baseline to 45.2-52.1 billion Euro, occurring primarily in Sumatra and Kalimantan. Compare to 2010, national employment baseline will increase by 2.1 million jobs. With increasing global oil palm demand, it will rise to 2.5-2.9 million jobs. Sumatra GHG emission baseline will increase by 20.47 million tons CO2e, and rise to 24.2-27.8 million tons CO2e with increasing global demand. Under increasing global demand, Kalimantan land use will increase by 1.5-1.7 million ha and by 1.3-1.6 million ha with land-use intensification program. The Sumatra lowland rain forest will increase its potential species loss from 494 to 587-677 species for mammals if there Is increasing global demand on oil palm. With land-use intensification program, this potential species loss decline to 535-618 species. Other species taxa also are under threat due to the high global demand on oil palm. This study demonstrates the trade-off between socioeconomic and environmental consequences Land intensification reduces the pressure for land expansion and biodiversity loss. This study highlights the important to control global demand on oil palm to protect habitats with high biodiversity. The application and its limitation of this coupling method are also highlighted in this paper.
