A new global meta-analysis published in the journal Nature has shown that genetic diversity is being lost worldwide. Genetic diversity is critical for species to adapt and survive in changing environments, yet human activities like habitat destruction, the introduction and spread of new diseases, and activities like hunting or logging have been linked to its decline.

The study is the most comprehensive analysis of its kind, examining over 80,000 published articles and finding evidence of genetic diversity loss across terrestrial and marine ecosystems. However, the research also highlights that conservation actions show promise in reversing these declines. Strategies such as population supplementation, habitat restoration, and invasive species control may maintain or even increase genetic diversity, offering hope for biodiversity conservation.

This study underscores the urgency of proactive conservation efforts. By acting now, we can help safeguard genetic diversity and the resilience of species worldwide.

We have prepared a policy brief summarising key findings and recommendations to ensure this vital information reaches policymakers, conservation practitioners, and researchers. The brief emphasizes the importance of genetic monitoring, the use of existing datasets, and integrating genetic considerations into biodiversity risk assessments.
