During an exhibition for the community, ARU students presented appropriate technologies taught at the university. This included: vermiculture, micro-banana propagation technology, hydroponic fodder, indigenous micro-organisms, organic fertilizer and pesticides. Especially the earthworms grown as nutritious food for animals caused a lot of attention of the guests.
The visitors also saw technologies that promoted clean water like rainwater harvesting systems, domestic water pumping and water transportation by a hydraulic ram pump. The students also demonstrated ethno medicine in the arboretum and renewable energy technologies like solar panels .
The participants were amazed by the 4th Industrial Revolution (4IR) technologies which embrace green energy use, need less involvement of humans and require , extensive use of communication technologies such as smartphones and internet.
The students use all these technologies during field practice and their 1-year internship. They are mentored by ARU graduates (the URDT Epicenter Managers) who also teach them the practicalities of the visionary approach to rural transformation.
Students learned that communities choose technologies that are appropriate and most relevant to their aspirations. The appropriateness of the technology is judged by its: Affordability, Reliability, Efficiency, Low carbon print, and Simplicity.
