On 31 March 2021, Francesco Orsini professor of UNIBO and member of International Society for Horticultural Science (ISHS) presented a workshop on soilless cultivation in urban/per-urban areas under the title of What future for urban horticulture in Africa at the All Africa Horticultural Congress. It was an event with 1,500 participants, it was a pleasure to make our contribution to it! Here you have the link to the seminar: https://www.youtube.com/watch?v=kWpj61sFepk&t=675s
