Many different educational and training sessions focusing on science journalism have been offered to journalists in Africa in the past decades. However, there is still insufficient quality reporting on health, environment, technology and science. We propose a new, flexible and needs-oriented concept for the professionalization of journalists. Its main elements are peer-to-peer mentoring and building of professional associations using online tools for training, networking and journalistic research, a combination of approaches and an in situ delivery. It has been put into practice through the Science Journalism Cooperation (SjCOOP) project in Africa and in the Middle East.
