This study provides a practice insight into campus/community co-farming as a communication experience connecting civic participants and experts in exploring the potential applications of smart agriculture. The observation focuses on participants' perceptions of smart-agri practices. The objectives of smart-agri practices have been identified to reduce negative environmental impact and meet local challenges; their development corresponds to the civic value-driven experience of promoting sustainable agriculture with low-risk, trackable information. Relatively few studies on smart-agri communication have engaged with the non-expert level. The findings highlight a viable participatory communication form of problem-solving, the public's trust of expertise, and a vision for inclusive socio-economic applications of smart agriculture.

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.

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.

Building a strong and trustworthy communication network to report unusual signs of disease will facilitate Australia's response to a foot and mouth disease (FMD) outbreak. In a four-year study, the FMD Ready Farmer-led surveillance project adopted the Agricultural Innovation Systems (AIS) framework, modelling transformation of how knowledge is co-created, valued, and communicated. The FMD Ready project has highlighted the need for multiple stakeholders' voices to be heard, and the importance of regulatory bodies to listen. Relationships take time and need to be valued as a necessary tool in a participatory, innovative approach to animal health and disease management.

Concepts underpinning participatory science communication have much to offer science communication training and capacity building. This paper investigates a capacity building program with 15 science communicators from nine African countries involved in a six-week program in Australia. Data was collected via surveys, observations, informal interactions and ongoing relationships tracking program outcomes. Key features with a participatory nature included: holistic programs giving participants diverse skills and entry points; ensuring participant's freedom, agency, autonomy and self-efficacy; real-world networking as a self-directed participatory process; participant-led design processes to build skills for creating programs; and, embedding training in real-world contexts with deliberately selected publics.

Justin Gest's book “Mass appeal. Communicating policy ideas in multiple media” illustrates how to communicate research effectively. He offers insights into different mediums and provides practical examples of each. While the author has a background in policy research, his ideas and insight are of interest to a much broader audience with an interest in science communication.

Citizen science opens the scientific knowledge production process to societal actors. In this novel collaboration process, scientists and citizens alike face the challenge of new tasks and functions, eventually resulting in changing roles. Role theory provides a way of conceptualizing the roles that people take in communication and interaction. We use role theory to create a framework that identifies scientists' and citizens' tasks in citizen science projects, main aims of communication, spaces they interact in, and their roles — thus providing a structured way to capture communication and interaction in and about CS for further scientific reflection and practical application.

Accurate news media reporting of scientific research is important as most people receive their health information from the media and inaccuracies in media reporting can have adverse health outcomes. We completed a quantitative and qualitative analysis of a journal article, the corresponding press release and the online news reporting of a scientific study. Four themes were identified in the press release that were directly translated to the news reports that contributed to inaccuracies: sensationalism, misrepresentation, clinical recommendations and subjectivity. The pressures on journalists, scientists and their institutions has led to a mutually beneficial relationship between these actors that can prioritise newsworthiness ahead of scientific integrity to the detriment of public health.

The ‘Born or Built? — Our Robotic Future’ (‘BOB?’) exhibition examines relationships between humans, robots and artificial intelligence. It encourages visitors to explore ethical and social issues surrounding these new technologies and invites visitors to post their own questions. We examine visitor responses to the exhibit “A of the Day”, which encourages visitors to engage by writing down their own question prompted by their experience in ‘BOB?’. As responses were submitted, it became apparent that the questions posed by visitors were potentially a valuable contribution to future science communication policy about robotics, and to those designing and implementing these technologies. We performed a content analysis that distilled themes in visitors' open-ended questioning that conveyed visitor knowledge and insight into what science communication about robotic technologies needs to address. Taken this way, visitors' questions form a moment of dialogue between the public and science communicators, engineers and researchers in which visitors contribute their knowledge and ideas about robotics. Such moments of dialogue are potentially valuable if the public is to be included in the development of robotics technology to build trust in robotics technology.

This essay examines a highly popular comic series published in Spain between 1969 and 1970 which focused on Felix Rodríguez de la Fuente (1928–1980), a prominent and influential naturalist and media icon, as main character. These comics constitute a remarkably illustrative example of the use of popular media in processes of construction of natural history knowledge. Situated in the complex final years of Franco's regime, they allow us to probe the combined role of science, media, and celebrity in the construction of a visual environmental culture through storytelling strategies designed to engage young audiences in naturalist-like practices.
