In Liberia, five local students have initiated projects to improve water and electricity supply. The foundation for these projects was laid by the Winter School «Water & Sun», organized by the Platform for Interdisciplinary Collaboration and Sustainable Development in the Global South at OST, in collaboration with local partners and the Bowier Trust Foundation Switzerland. These are the first milestones of the new educational project CHub Liberia: a Swiss knowledge hub aimed at sustainably promoting development in the region.
