Pita Verweij, is a Researcher at the Copernicus Institute of Sustainable Development. Throughout the years, her principal field of research has been land use and biodiversity in the context of natural resource management. She worked in a wide range of tropical ecosystems, from lowland forests to mountain grasslands, and from semi-arid to extremely humid. In recent years, Pita Verweij strengthened the link between the development and application of ecological knowledge and policy-making in her work. This is demonstrated by her research on the valuation of biodiversity and ecosystem services, and the development of ecological knowledge that addresses problems in nature conservation and spatial planning.
