The publishing world has undergone radical changes in recent years. The promotion of knowledge and scientific communication is essential for our society and serves as a key tool for decision-making. It must be accessible to the public, including policymakers, stakeholders, and the citizens who fund research. While institutions and funding agencies are working to promote Open Access, inequalities persist, and gatekeepers continue to exert control. In this context, I will present and discuss the Diamond Open Access (DOA) model, with a particular focus on community-led geoscience journals such as Volcanica, Tektonika, Seismica, Geomorphica, Advances in Geochemistry and Cosmochemistry, and Geodynmica. As a co-founder, member of the steering committee, and production editor at Sedimentologika, I will detail the creation of this journal, which is hosted at the UNIGE Library, and provide insight into its operations. The DOA model, in turn, is emerging as a promising solution to ensure equal and sustainable access to scientific publications for all.
