Working towards a biodiverse planet

The work of our researchers and students contributes to the conservation and restoration of biodiversity. But what exactly is biodiversity, and why is it so important to preserve it?

Biodiversity refers to the variety of life in a given area—whether it is your balcony, the ditch behind your house, or an entire country. It includes all animals, plants, and microorganisms living in that area, both above and below ground. All those organisms play one or more roles there, for example as a decomposer, pollinator or food source. This way, all these organisms are connected. Together, they ensure that nature continues to function properly.

Due to human activities, biodiversity is globally under pressure. According to the International Union for Conservation of Nature (IUCN), over 45,000 plant and animal species are at risk of extinction. This is driven by factors such as habitat loss, overfishing, overhunting, pollution—such as excess nitrogen—and the impacts of climate change.

Loss of biodiversity is a problem for us all. Because nature provides clean air and water, supplies us with food, and helps protect us from flooding and drought.

Our researchers study the state of biodiversity on our planet. They explore its role in nature and the factors that drive changes in biodiversity. They also investigate effective strategies for preserving and restoring biodiversity. From the start of their studies, our students also actively engage with biodiversity, working alongside researchers to help create a more biodiverse world.
