UNU-FLORES-Challenge is a technology-promoting service-learning project related to SDG 2  (Zero Hunger). Contributing to SDG-Campus, it is conjointly supported by UNU-FLORES and operates under the service-learning module praxiSDG in methodological and organizational terms. Participants are committing themselves to sustainability efforts of UNU-FLORES , learning to act as change agents in programme design, strategy or operative activities (service). Eager to leaving meaningful handprints, participants will design their individual projects in a collaborative way, including precisely formulated project goals for self-determined, sustainability-related action. This enables participants not only to learn about the significance of volunteerism, but also to evaluate and reflect on its opportunities and risks vis-à-vis their individual study contexts (learning).
