The second Global AgriKnowledge Share Fair (www.sharefair.net) was an opportunity for regional networks such as KariaNet (www.karianet.org ) and Menarid to present their challenge of sustainability to an experienced and well-informed crowd in order to learn from their knowledge and lessons learned. This session was jointly presented by kariaNet and Menarid in the form of a chat show, whereby both networks were introduced and the assets, challenges and opportunities of sustaining networks were explored.
