This study aims to analyse the role of civil society organisations (CSOs or civil society organisations) in their relations with the Spanish science and technology system, from the perspective of studies on the social perception of science and scientific culture. In addition to analysing the current situation, the project aims to stimulate the active participation of CSOs in R&D&I, to strengthen the links between the scientific community and these organisations, and to promote scientific culture and knowledge of the Spanish science and technology system among the people who make up these organisations.
