Tracking progress towards the United Nations’ Sustainable Development Goals (SDGs) requires high-quality, timely, and accessible data, often in areas where data are rarely available. Problems exist due to socioeconomic variations between countries and the qualitative nature of certain indicators in their definition. Citizen science has the potential to contribute to several SDGs. However, whilst citizen science’s potential to contribute towards SDGs is well documented, limitations exist when measuring the impact that citizen science has made toward SDG progress. To better understand the issues and prospective solutions surrounding impact assessment towards SDG progress, this work presents the outcomes of semi-structured interviews with citizen science project coordinators. They reveal the complex nature of impact assessment within a citizen science context. Coordinators demonstrate greater confidence when the project is easier to relate to the SDGs, and the project methodology can objectively measure indicators. Issues exist, however, when considering SDGs with a broader, global context, those more difficult to link to project goals and when the project’s impact on them happens at timescales beyond the funding period. If the full potential of citizen-science contributions to the SDGs is to be realised, approaches are needed to fully consider practitioners’ needs and motivations.

The growing interest in citizen science has resulted in a new range of digital tools that facilitate the interaction and communications between citizens and scientists. Considering the ever increasing number of applications that currently exist, it is surprising how little we know about how volunteers interact with these technologies, what they expect from them, and why these technologies succeed or fail. Aiming to address this gap, JCOM organized this special issue on the role of User Experience (UX) of digital technologies in citizen science which is the first to focus on the qualities and impacts of interface and user design within citizen science. Seven papers are included that highlight three key aspects of user-focused research and methodological approaches. In the first category, "design standards", the authors explore the applicability of existing standards, build and evaluate a set of guidelines to improve interactions with citizen science applications. In the second, "design methods", methodological approaches for getting user feedback, analysing user behaviour and exploring different interface designs modes are explored. Finally, "user experience in the physical and digital world" explores crossovers with other fields to improve our understanding of user experiences and demonstrate how design choices not only influence digital interactions but also shape interactions with the wider world.

This chapter considers the interface of citizen science, health, and environmental justice. We review citizen science research undertaken by civic educators, scientists, and communities that aims to broaden scientific knowledge and encourage democratic engagement and, more specifically, to address complex problems related to public health and the environment. We provide a review of the current state of existing citizen science projects and examine how citizen science, health, and environmental justice impact each other, both positively and negatively. Specific challenges that relate to these projects are discussed, especially those that are not obvious or applicable to more traditional citizen science projects.

Online citizen science platforms increasingly provide types of infrastructural support previously only available to organisationally-based professional scientists. Other practices, such as creative arts, also exploit the freedom and accessibility afforded by the World Wide Web to shift the professional-amateur relationship. This paper compares communities from these two areas to show that disparate practices can learn from each other to better understand their users and their technology needs. Three major areas are discussed: mutual acknowledgement, infrastructural support, and platform specialisation. We discuss the advantages and disadvantages of differing practices, and lessons that can be learnt for online citizen science platforms.
