Open science offers the means to develop and build tools to help us overcome conflicts (e.g. water sensors in dry regions and seasons). Open science and data literacy equip us to critically think about the root causes of and potential solutions for conflicts. And finally, open science can serve as a vehicle of peace-building in communities through collaborative events such as hackathons or makeathons. After sharing their experiences, the participants will develop a joint framework for open science and peacebuilding in action. This session will be facilitated by Obasegun Ayodele of Vilsquare / Nigeria.We will explore one area of open science through hands-on demos, making and peer-to-peer learning: DIYBio. Doing biotech research yourself means creating alternative, local and low-cost alternatives to biotech protocols as well as commercialized equipment. As part of the Open Bioeconomy Lab, Harry Akligoh at Kumasi Hive / Ghana and Nelly Flora Mengue Ango at Mboalab / Cameroon are using low-cost incubators to work on the Open Enzyme project and locally produce Kossamtor yoghurt respectively. Other examples of open science in action are Public Lab‘s Community Microscopes and DIY soil moisture sensors.
