Bioleft is a community committed to building a fairer and more sustainable seed system for the production, exchange, and participatory breeding of key food crops. Since 2016, we have been working on the development of a digital platform, a set of open licenses for material transfer, and participatory plant breeding programs to build an open-source seed network in Argentina. We believe in the power of collective intelligence and open knowledge to create a seed system that recognizes the role of farmers in the conservation and improvement of seeds, promoting the availability of biodiverse and resilient crop varieties.
