Held for the first time on the Chinese mainland, the four-day conference in the provincial capital city of Kunming has drawn up the Kunming Declaration to promote unity in the global bar-coding community, a Chinese state run news agency reported.

"The declaration in Kunming is one of the most important events in the history of biodiversity science. We are following a global trend to open up data. It's critical for protection of biodiversity in future," Canadian scientist Paul Hebert said on Thursday.

The Kunming Declaration, signed by 400 scientists from more than 40 regions and countries, calls for international cooperation in DNA bar-coding technology and industry standards.

DNA bar-coding, initially proposed by Paul Hebert in 2003, is a way to identify species by a short genetic marker. The technology has been adopted in fields such as species identification and biological medicine, according to Li Deshu, dean of Kunming Institute of Botany.

"The technology of DNA bar-coding is of great significance in global biodiversity protection," Li said, adding that countries like Canada and Japan have set up databases.

International Barcode of Life project has registered more than three million pieces of information on nearly 200,000 species.

British scientist Richard Lane said that a global database could help in monitoring biodiversity.

"The new technology could be applied in many areas, helping us to fight climate change and keep human progress sustainable," he added.
