BATATA aims at identification of conceptions of sustainable bioeconomy being endorsed in the Global South. Empirically, it focuses on politically under-represented social groups in Tanzania, a biomass-rich country in Sub-Saharan Africa. The identified visions will be compared with those supported by the political mainstream in Tanzania and with the concepts of a sustainable bioeconomy from the Global North with regard to their underlying values. The Ethics Center aims at an ethical analysis of reasons provided for and against the realization of these visions of a sustainable economy.
