Reversing the loss of biodiversity in the world’s terrestrial, freshwater and marine ecosystems is one of the greatest challenges we face. However, effective biodiversity conservation requires not just the efforts of conservationists alone, but also relies on contributions, commitment and cooperation across many disciplines and sectors. In Europe, governments, NGOs, citizens and businesses are already working alongside ecologists and conservationists in response to the biodiversity crisis.
8th European Congress of Conservation Biology (ECCB)
Welcome to the 8th ECCB in Leiden, where researchers, policymakers, and practitioners will have the opportunity share knowledge and exchange ideas. Not only will this congress present exciting scientific research, but we will also showcase successful collaborations and build bridges between stakeholders and disciplines. The meeting will provide an important opportunity to tackle the issues that we all face in everyday life, including how to communicate the biodiversity conservation message effectively, and how to maintain a dialogue in difficult political or social circumstances.
During this week we will try to find answers to our key question: how can biodiversity be safeguarded effectively in the long term?
