From a strategic communication perspective, for any communication to be effective, it must be audience-centered, with content and delivery channels that are relevant to its intended target. When trying to reach culturally specific communities or other groups that are not otherwise connected with science research, it is crucial to partner with community members to co-create content through media that is appealing and culturally competent. This commentary considers some examples including storytelling through ‘fotonovelas’ and radio stories, community drama and serious games.

Many of the earliest drivers for improved scientific literacy and understanding were based on the assumption that science and technology is all around us, and yet there are some spaces and communities that are neglected in science communication contexts. In this brief comment, Clare Wilkinson introduces a series of ten commentaries, which further probe neglected spaces in science communication.

‘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 uses a case study of Uganda and the country's attempts to adopt genetically modified organisms (GMOs) to demonstrate how activists have become communicators of scientific knowledge in the digital age. The digital age allows activists to share their information and collaborate with those who can push their agenda. I argue that anti-GMO activists have positioned themselves as influencers in a debate where weight-of-scientific evidence seems to have been overshadowed by perceptions, largely driven by socio-democratic considerations that require participation in technological uptake.

As “alternative” [Maeseele, 2009] science communicators, young people (of pre-voting age) have an important role to play in the climate communication arena. Youth have access to rhetorical resources associated with evidence-based and emotional appeals. However, they are challenged by political, media and public entities on their ability to effectively engage with politicised scientific issues. Their credibility and authority to speak on climate issues are challenged. This piece takes a rhetorical lens to a current youth climate change advocacy case study, the ‘School Strike for Climate’. I argue that Australian youth are criticised for being politically inexperienced in attempts to silence them from speaking out about Australian climate change policy. Implications for science communicators working in the climate change space, and the ‘Strike’ participants themselves are discussed.

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?

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.

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.

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.

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.
