Activists, social organizations and members of citizen collectives in Mexico and Latin America have assumed not only the fight for water and territory, but also the difficult task of interacting with experts in different scientific fields, and the challenge of placing their causes in the public space. They take the role of cultural mediators between affected people, scientists and politicians within hybrid transdisciplinary working groups. Within the framework of these groups' actions, a new current of communication of science has emerged, one that shifts its interest from encouraging involvement with scientific knowledge for its own sake, to untangling, understanding and communicating socio-environmental issues for the explicit purpose of contributing to social transformation.

Environmental NGOs play a vital role in public climate communication through their awareness-raising activities and educational campaigns. This commentary points to a potentially problematic implication of their role as climate science advocates which includes the general tendency to attribute environmental changes and extreme weather events to climate change. These climate-centric framings, however, may not resonate with the lived experiences and belief systems of local communities, not even in geographically vulnerable areas. I draw on local case studies to show that communities often express a sense of “shared responsibility” between global carbon dioxide emissions and ecologically deleterious local practices such as shrimp farming (in Bangladesh) and cutting trees (in the Philippines). As a consequence, the studies show mismatches between activists' attributions of local circumstances and events, and local communities' ways of knowing their local circumstances.

‘Alternative’ and ‘activist’ are words with meanings strongly influenced by the social context of their use. Both words refer to concepts, things or people that stand in opposition to other concepts, things and people that are often taken for granted, and not elucidated. In science communication studies, ‘science’ is often an unelucidated concept. Indeed, in recent history, efforts within academia to map the perspectives on science that we might explore with the public have proven fractious, to say the least. In everyday science communication practice, however, we can readily see that there are many differing perspectives on science (and its alternatives) and on how, as the activists urge, it should (or should not) be deployed. This commentary encourages a symmetrical approach to understanding ‘alternative’ and ‘activist’ in the context of science communication, which has the potential to bring out a range of perspectives and provide a context for democratic engagement.

This commentary describes the work of the NGO Danish Seed Savers, working with heritage plants, highly prioritized by The Food and Agriculture Organization of the United Nations. The Danish Seed Savers act as activists, when they work to change the implementation of EU seed-legislation. At the same time, they have a seat in the Danish Committee on Plant Genetic Resources and help the Ministry of Food to protect and communicate about heritage plants. The commentary reflects on the role of the Danish Seed Savers. They are science communicators and activists but asks: are they alternative?

Often, new social movements engaged with science and society are characterised as contesting objectivity; the neutrality of modern science seeking to legitimise ‘lay perspectives’. It has been an article of faith among scholars to view third world movements as anti-science, anti-modernity and post-developmentalist. This commentary describes ideological framework, modes of action and organisation of the All India People’s Science Network (AIPSN), one of the People’s science movement (PSMs) active for more than the past four decades. They dispute the dominant development trajectory and science and technology-related policies for reinforcing the existing inequities. Nevertheless, they see ‘science’ as a powerful ally for realising their radical emancipatory vision of ‘science for social revolution’. Mobilising ‘science activists’ as unique alternate communicators, they strive for lay-expert collaboration. The canonical framing of third world social movements as postcolonial and anti-modern does not capture this unique case from India. Further studies are required to tease out such strands of social movements elsewhere.

For many decades, NGOs and social movements have acted as “alternative” science communicators. They have made strategic use of science to promote their ideological stances, to influence political and/or economic decision-making and to motivate civic action. To date, however, our understanding of science communication in activism has received little critical attention. This set of commentaries acts as a starting point for further research and reflection. The different cases and perspectives urge readers to consider the impact, democratic legitimacy, and relevance of alternative science communication, and the challenges that alternative science communicators pose for science communication and society.

This book review considers the contribution of Communicating Science, A Global Perspective to our understanding of the history of science communication across the globe. With 40 chapters and nearly 1000 pages of text, this substantial book provides insights into the unique histories of science communication in 39 countries across all regions of world.

This paper identifies the diverse ways in which participants engage with science, through the same citizen science project. Using multiple data sources, we describe various activities conducted by citizen scientists in an air quality project, and characterize the motivations driving their engagement. Findings reveal several themes, indicative of participants motivations and engagement; worried residents, education and outreach, environmental action, personal interest and opportunistic engagement. The study further illustrates the interconnectivity between science communication and citizen science practices and calls for nurturing this relationship for the mutual advancement of both fields.

U.S. and other publics perceive STEM (science, technology, engineering, and mathematics) fields as masculine and scientist as a male occupation, but Japanese public perception remains unstudied. Using an online survey, we identified keywords associated with physics, chemistry, mechanical engineering, information science, biology, and mathematics. A second online survey showed that the Japanese public perceived both keywords and fields as masculine. This trend was stronger in individuals with less egalitarian attitudes towards gender roles. We suggest that attitude towards gender roles contributes to the masculine image of science in Japan.

This paper analyzes a new initiative in Brazil’s ‘Ciência Hoje’ magazine, called “Interactive Articles”, aimed at understanding how stakeholders relate to interactivity when writing a science communication article. We investigated participation in two platforms (magazine website and Facebook page) and interviewed the authors concerning the tool’s impact on their articles. Comments were examined using intensity analysis and content analysis, while interviews were analyzed with the collective subject discourse method. The study concluded that the novel initiative presented positive results in terms of interactivity and was regarded as public engagement and contextual model of science communication from the interviewed authors.
