Several actors have been involved, and are currently or prospectively involved in the introduction of biochar systems to Ethiopian cropping systems. Among these actors are the universities of Jimma (ETH), Haramaya (ETH), Injibara (ETH), Hawassa (ETH), Bahir Dar (ETH), Addis Abeba (ETH), Dilla (ETH), Cornell (USA) and James Cook University (AUS). One of the most comprehensive activities was probably the joint research programme of Jimma and Cornell Universities, that have developed a set of “indigenous biofertilizers” on the basis of biochar and bone char (charred residues of animal bones). Apart from universities, also the Amhara Regional Agriculture Research Institute (ARARI) and the Mekelle Agricultural Research Centre have contributed to biochar research in Ethiopia. Some of these research activities have identified promising feedstock sources to produce biochar, such as, coffee husks, Prosopis juliflora, or animal bones. But none of them could present a well-suited technology to convert this biomass to biochar.
