The OPAL project aims to improve the management of oil palm landscapes across Asia, Africa and Latin America. We do so by engaging stakeholders and boundary partners at regional, national and local levels with plausible scenarios of oil palm development. These scenarios are developed through integrated platforms that merge the social, economic, and ecological drivers shaping oil palm development. We assess the various outcomes of scenarios in terms of their implications for biodiversity, ecosystem services and human well-being. The project takes places in four countries: Cameroon, Colombia, Indonesia and Switzerland.
