Much of the vanilla that flavours our ice cream today is artificial, derived from the genetic signature of a plant that hundreds of years ago was known only to an Indigenous Mexican tribe.
The plant's sequenced genomic information, available on public databases, was used as the basis for a synthetic flavouring that today competes with vanilla grown in several countries, mainly by small-scale farmers. Few, if any, benefits of the lucrative scientific advance have trickled down to the communities that gave us vanilla in the first place.
"Wild genetic resources and pharmaceuticals ... are a multi-multi-billion dollar businesses. They clearly are profitable... that's not in dispute," Charles Barber of the World Resources Institute think tank told AFP.
"A great deal of really valuable information has fed into the system from research and utilization of wild genetic resources. And there is no mechanism currently to compensate the people where this information is coming from" in the form of digitally sequenced data, he added.
Much of the information comes from poor countries. Fair sharing of the gains derived from digitally stored genetic sequencing data has been a headache for negotiators at the COP16 biodiversity summit into its second week in Cali, Colombia.
At the last conference, in Montreal in 2022, 196 country parties to the UN's Convention on Biological Diversity (CBD) agreed to create a benefit-sharing mechanism for the use of digital sequence information (DSI). Two years later, they still need to resolve such basic questions as who pays, how much, into which fund, and to whom does the money go?
'Cheap and very fast'
The issue is a complex one. There is little debate that genetic data-sharing on mostly free-access platforms is crucial for human advancement through medicine and vaccine development, for example.
But how to quantify the value of the sequenced information itself? And should the first people to discover a plant's particular usefulness be compensated?
"Sequencing technology has become so advanced that you can go with a... handheld device a little bit bigger than a cell phone and you can literally sequence a genome in an hour or two and upload it as you sequence it," Pierre du Plessis, a DSI expert and former negotiator for African countries at the CBD told AFP.
