This new strategic assessment from Defra explores how global biodiversity loss and the collapse of critical ecosystems could affect the UK’s resilience, security and prosperity.

This assessment is an analysis of how global biodiversity loss and ecosystem collapse could affect UK national security.

It shows how environmental degradation can disrupt food, water, health and supply chains, and trigger wider geopolitical instability. It identifies 6 ecosystems of strategic importance for the UK and explores how their decline could drive cascading global impacts.

This assessment, which was developed by analysts and experts across HM Government, supports long-term resilience planning. Publishing the assessment highlights opportunities for innovation, green finance and global partnerships that can drive growth while safeguarding the ecosystems that underpin our collective security and prosperity.
