In the past decade, scientific research that relies on the collaboration of citizens has grown exponentially. Be it for collecting data on bird migrations, noise pollution, or empty houses in a neighbourhood, or for analysing pictures of malignant cells or distant stars, or for transcribing ship logs or translating Egyptian hieroglyphs (all examples of real citizen science projects), there are countless opportunities for citizens to get involved in the work done by scientists and contribute to the accumulation of scientific knowledge. Also, other levels of engagement are possible beyond collecting or analysing data: suggesting research topics, designing research methods, interpreting research results, discussing and disseminating findings.
This Mètode monograph brings together contributions from Spain, Portugal and Japan and from the perspective of diverse kinds of citizen science. From measuring radioactivity after a nuclear disaster to exploring mental health support networks, debating how to improve science communication, or measuring the commitment to the sustainable development goals through a game to generating rainfall maps, the articles explore diverse instances where citizens and science intertwine. Concomitantly, issues such as levels of participation, the potential for doing citizen science in the social sciences, impacts of education or the role of digital applications are discussed.
