This essay approaches the question: ‘What does participatory science communication for transformation mean in Colombia?’ The answer comes from an examination of the public policy instruments that have promoted participatory scientific communication through the concept of social appropriation of science, technology, and innovation (STI). In the gaze of these public policy instruments, it is evident how the social appropriation of STI has been intended as a means of transformation.

Participatory science communication featured in several sessions and individual papers at the 2021 online conference of the Public Communication of Science and Technology (PCST) Network. This coverage recognises the drive away from linear communication to more participatory forms of science communication. In this special edition we present practice insights, papers and essays that explore participatory science communication. These contributions explore definitions, processes and describe case-studies of participatory science communication which involve a variety of publics, from young school students to Indigenous groups to farmers. In this introductory editorial we reflect on the papers, describe the growth of a participatory approach as part of the continuing evolution of science communication; explore a definition for participatory science communication; and consider some of the key concepts and issues that emerged.

This practice insight focuses on lessons learned while completing a research project designed to compare the relative effectiveness of three communication strategies in rural communities relative to motivating citizens to take action on a public health issue, specifically Type 2 diabetes. Our main arguments are: 1) Engaging citizens in any type of communication related to public health or science action requires first assessing a community's readiness for that action; and 2) Community readiness — rather than communication methodology — is the better predictor of citizens' participation in collective or individual actions on public health and science issues.

Traditionally, the Royal Institution's Christmas Lectures have always adopted a deficit model for communication, with one or two invited scientists giving lectures to an audience present at the Royal Institution (Ri) and, since 1936, an audience watching the lectures on television at home. As trends in public engagement have tended towards more dialogue or participatory models, the Ri has made efforts to create a programme of events around the lectures: extending the experience outside of the lecture theatre and giving audiences more opportunities to experience live events and participate in discourse. In this paper, we explore data collected as part of an 18 month evaluation of the Christmas Lectures and their associated events. We focus on data collected at events designed to create live and interactive experiences beyond the lectures and evaluate these participatory approaches. The paper shares this learning to enhance the extension of traditional science communication towards science participation.

In this “practice insight” we present a series of experiences run by Association Traces, injecting participatory approaches into science engagement activities by valuing the knowledge of the public rather than focusing on their ignorance. Starting from the observation that a sort of hybridization is occurring between cultural activities and public engagement with science on one side, and co-creation and participatory activities on the other, we provide some insight on the features of each approach. Examples are then used to highlight the potential value of this hybridization: as a way of making participatory activity more recognizable and accessible to a wide audience; to ensure that scientists have a professional interest in engaging in the communication activity; to raise a sense of ownership and empowerment in the audience, etc. These examples will eventually show that participation may lead to science communication practices that are socially-inclusive and/or productive for research, and ideally both.

The language of science communication has moved from deficit to dialogue and talk of a ‘new social contract’ with the public ‘invited to participate’. This paper outlines a practitioner path that begins with storytelling and moves to a more participatory mode of practice of science communication for adaptation to climate change at the community scale. I outline personal practitioner reflections, specifically the need to consider issues of power, place, pain and the need to challenge assumptions. I propose the need to consider context, many forms of local knowledge and expertise, social learning, plus the pain of historical, contemporary or projected loss.

Participatory media has the ability to engage people in stories of science in ways that are personal, profound and culturally relevant. This essay launches from my experience as a scientist-turned-filmmaker and my establishment of the Ocean Media Institute, a global media collective that serves as a participatory platform for the communication of ocean science. Through collaboration and innovation, we as science storytellers have the ability to shape narratives that are factual, evidence-based and embrace greater inclusivity. Only when we invite diverse perspectives that draw from all ways of knowing, will we be able to provoke deeper dialogue and ignite change.

In this practice insight, an art-based, participatory intervention (#finaltrashtination) is presented as higher education assignment in environmental and climate change communication. The project #finaltrashtination made dominant environmentally destructive ways of wasting visible and stimulated students to take responsibility, advocacy and authorship for transformation. Beyond the one-day eco-culture jam, the project engaged the wider public through conversations about a specific environmental problem. Thus, the project shows how conversational problematization and sensemaking around scientific facts can be initiated by using eco-culture jams promoting very unsettling moments of reflection.

Young children are actors usually excluded from political decisions and also from many science communication projects. Participatory science communication models can help to connect their everyday life with both local policies and science-related content. Using visual methodologies for engagement, we aimed at understanding what preschool children prefer in the city landscape. Results show how young children envision a “better city” and how that construction might defy current scientific knowledge. It further illustrates how science communication can be used to co-produce new knowledge, contributing to the debate about people's needs and perceptions related to science-based options.

While short-term participatory science communication activities have been well researched, long-term programs have received scant attention. Analysing survey data and participant discussions, I investigated interactions between Australian farmers and scientists engaged in the Climate Champion Program (2009–2016). I compared their interactions to three theorised science communication models: deficit, dialogue and participatory. I found their interactions illustrated a mix of the characteristics of all three models. While farmers and scientists appeared to be motivated to interact by deficit and dialogue objectives, respectful and trusting relationships emerged from long-term participation, which was key to making deficit- and dialogue-style communication more effective.
