UNESCO ‘eDNA’ Initiative to ‘Unlock’ Knowledge for Biodiversity Protection

Paris – To understand the richness of biodiversity across World Heritage marine sites, the UN scientific organization launched on Monday a project to protect and preserve biodiversity, based on the study of environmental DNA – cellular material released from living things into their surroundings.

Launching the new programme, the UN Educational, Scientific and Cultural Organization (UNESCO) said that scientists and local residents would take samples of genetic material from fish waste, mucous membranes or cells, eDNA, to monitor species.

“Marine World Heritage sites play a critical role in protecting marine ecosystems of exceptional universal value and provide opportunities for the public to appreciate and preserve marine environments,” reminded UNESCO Assistant Director-General for Culture, Ernesto Ottone Ramírez.

UNESCO said that the two-year initiative would help measure the vulnerability of marine biodiversity to climate change and its impact on the distribution and migration patterns of marine life across World Heritage sites.

The eDNA project, which involves collecting and analyzing samples from the environment – such as soil, water and air – rather than an individual organism, will also better monitor and protect endangered species included in the International Union for Conservation of Nature (IUCN) Red List. 

“Climate change is affecting the behaviour and distribution of underwater life and we must understand what is happening so we can adapt our conservation efforts to evolving conditions,” explained the UNESCO official.

UNESCO’s marine World Heritage sites are recognized for their unique biodiversity, outstanding ecosystems, or for representing major stages in Earth’s history.

In the context of the UN Decade of Ocean Science for Sustainable Development (2021-2030), the project was launched to contribute to the understanding of global trends and knowledge to preserve marine ecosystems.

Guided by expert support, the eDNA project will engage local citizens to gather material, so samples such as particles gathered through water filtering, can be genetically sequenced in specialized laboratories, without having to disturb animals themselves.
