Everybody depends on biodiversity – the diversity of genes, populations, species, communities and ecosystems. Globally, the services that ecosystems provide to people are thought to be worth around twice the global gross national product.
Biodiversity is declining in the face of human activity. We convert natural habitats into agricultural or urban land, harvest animal and plant species for food and other uses, spread pest and disease species around the world, and change the climate. However, not every species or ecosystem is declining equally. Policymakers need to be able to predict ecosystems’ ability to support people under different scenarios of how human societies might develop, but existing models are too simple to do a good job. My project has several research strands that aim to meet the urgent need.
