The paper presents a review of contributions to the scientific discussion on modern methods and tools for public participation in urban planning. This discussion took place in Obrzycko near Poznań, Poland. The meeting was designed to allow for an ample discussion on the themes of public participatory geographic information systems, participatory geographic information systems, volunteered geographic information, citizen science, Geoweb, geographical information and communication technology, Geo-Citizen participation, geo-questionnaire, geo-discussion, GeoParticipation, Geodesign, Big Data and urban planning. Participants in the discussion were scholars from Austria, Brazil, the Czech Republic, Finland, Ireland, Italy, the Netherlands, Poland, the United Kingdom, and the USA. A review of public participation in urban planning shows new developments in concepts and methods rooted in geography, landscape architecture, psychology, and sociology, accompanied by progress in geoinformation and communication technologies. The discussions emphasized that it is extremely important to state the conditions of symmetric cooperation between city authorities, urban planners and public participation representatives, social organizations, as well as residents.

Introduction: Co‐production with communities is increasingly seen as best practice that can improve the quality, relevance and effectiveness of research and service delivery. Despite this promising position, there remains uncertainty around definitions of co‐production and how to operationalize it. The current paper describes the development of a co‐production strategy to guide the work of the ActEarly multistakeholder preventative research programme to improve children's health in Bradford and Tower Hamlets, UK. Methods: The strategy used Appreciative Inquiry (AI), an approach following a five‐step iterative process: to define (Step 1) scope and guide progress; to discover (Step 2) key issues through seven focus groups (N = 36) and eight in‐depth interviews with key stakeholders representing community groups, and the voluntary and statutory sectors; to dream (Step 3) best practice through two workshops with AI participants to review findings; to design (Step 4) a co‐production strategy building on AI findings and to deliver (Step 5) the practical guidance in the strategy. Results: Nine principles for how to do co‐production well were identified: power should be shared; embrace a wide range of perspectives and skills; respect and value the lived experience; benefits should be for all involved parties; go to communities and do not expect them to come to you; work flexibly; avoid jargon and ensure availability of the right information; relationships should be built for the long‐term; co‐production activities should be adequately resourced. These principles were based on three underlying values of equality, reciprocity and agency. Conclusion: The empirical insights of the paper highlight the crucial importance of adequate resources and infrastructure to deliver effective co‐production. This documentation of one approach to operationalizing co‐production serves to avert any misappropriations of the term 'co‐production' by listening to service users, stakeholders and other relevant groups, to develop trust and long‐term relationships, and build on the learning that already exists amongst such groups. Patient or Public Contribution: The work was overseen by a steering group (N = 17) of individuals, both professional and members of the public with experience in undertaking co‐production, and/or with some knowledge of the context of the two ActEarly field sites, who provided regular oversight and feedback on the AI process.

Since the introduction of Xerox PARC Map Viewer, there is a high growth in the number of Web GIS (Geographical Information System) applications for public use in different contexts. These applications instruct, advise and provide the tools for spatial analysis to their users, and the people who use them depend or rely on these systems. Many of these users are non-experts who have no GIS expertise and a limited understanding of spatial data handling. These inherent characteristics of non-expert interaction establish risk and uncertainty, which are further increased due to the complexity of Web GIS interfaces. These issues of uncertainty, risk perception and dependence are all trust-related aspects. Online trust has been repeatedly identified as a major concept for online information systems and its value recognised as it influences the intentions to use and the acceptance of online systems and the overall user experience. However, there is a very limited understanding as to exactly how trust is constructed when people, especially non-experts, interact with Web GIS. To improve knowledge in this domain, this article explores the theoretical foundations on how trust can be investigated in this context. Trust studies (mainly from the e-commerce domain) suggest that a trust-oriented interface design may improve the trustworthiness of online systems, and such attention can be given to Web GIS interfaces. Such studies are reviewed and their applicability is considered in the Web GIS context, taking into consideration their special characteristics. A case study is used to discuss how some features may potentially influence the trustworthiness of Web GIS applications. This article concludes by suggesting future research directions for the implementation of a holistic approach, which is necessary to investigate trust in this context. [ABSTRACT FROM AUTHOR]

Topology and its various benefits are well understood within the context of 2D Geographical Information Systems. However, requirements in three-dimensional (3D) applications have yet to be defined, with factors such as lack of users’ familiarity with the potential of such systems impeding this process. In this paper, we identify and review a number of requirements for topology in 3D applications. The review utilises existing topological frameworks and data models as a starting point. Three key areas were studied for the purposes of requirements identification, namely existing 2D topological systems, requirements for visualisation in 3D and requirements for 3D analysis supported by topology. This was followed by analysis of application areas such as earth sciences and urban modelling which are traditionally associated with GIS, as well as others including medical, biological and chemical science. Requirements for topological functionality in 3D were then grouped and categorised. The paper concludes by suggesting that these requirements can be used as a basis for the implementation of topology in 3D. It is the aim of this review to serve as a focus for further discussion and identification of additional applications that would benefit from 3D topology. [ABSTRACT FROM AUTHOR]

When faced with an environmental problem, locals are often among the first to act. Citizen science is increasingly one of the forms of participation in which people take action to help solve environmental problems that concern them. This implies, for example, using methods and instruments with scientific validity to collect and analyse data and evidence to understand the problem and its causes. Can the contribution of environmental data by citizens be articulated as a right? In this article, we explore these forms of productive engagement with a local matter of concern, focussing on their potential to challenge traditional allocations of responsibilities. Taking mostly the perspective of the European legal context, we identify an existing gap between the right to obtain environmental information, granted at present by the Aarhus Convention, and "a right to contribute information" and have that information considered by appointed institutions. We also explore what would be required to effectively practise this right in terms of legal and governance processes, capacities, and infrastructures, and we propose a flexible framework to implement it. Situated at the intersection of legal and governance studies, this article builds on existing literature on environmental citizen science, and on its interplay with law and governance. Our methodological approach combines literature review with legal analysis of the relevant conventions and national rules. We conclude by reflecting on the implications of our analysis, and on the benefits of this legal innovation, potentially fostering data altruism and an active citizenship, and shielding ordinary people against possible legal risks.

The global challenges of sustainability are encapsulated in the UN Sustainable Development Goals (SDGs), to which 193 member states are committed. However, a key challenge remains in identifying appropriate methods, indicators, and the ability to monitor progress towards these 2030 Agenda goals. Citizen Science (CS), as a scientific activity in which non-professionals voluntarily participate and cooperate with experts, has been used in Western countries to meet this challenge. Whether it also applies to achieving the SDGs of Asian countries like China is a question that needs to be answered with evidence. On this basis, the tasks of this study are twofold: first, through a literature review, we identify CS projects relevant to water that are happening in China; Second, we analyse the selected projects from three dimensions (scientific, participant, socio-ecological and economic) under an adjusted CS evaluation framework to determine their suitability in China. The results show that at least 19 water-related citizen science projects emerged in China since 2005, most of which are dedicated to improving water quality, with a few focusing on biodiversity monitoring. Multiple stakeholders, including non-governmental (NGO)/non-profit (NPO) organisations, academic institutions, governments and companies participate in these activities, with NGOs accounting for the most. CS has not expanded rapidly in the past 15 years, but most of the projects are still active, which shows the possibility of CS's further development in China after a good strategic framework has been formulated.

Citizen science is growing as a field of research with contributions from diverse disciplines, promoting innovation in science, society, and policy. Inter- and transdisciplinary discussions and critical analyses are needed to use the current momentum to evaluate, demonstrate, and build on the advances that have been made in the past few years. This paper synthesizes results of discussions at the first international citizen science conference of the European Citizen Science Association (ECSA) in 2016 in Berlin, Germany, and distills major points of the discourse into key recommendations. To enhance innovation in science, citizen science needs to clearly demonstrate its scientific benefit, branch out across disciplines, and foster active networking and new formats of collaboration, including true co-design with participants. For fostering policy advances, it is important to embrace opportunities for policy-relevant monitoring and policy development and to work with science funders to find adequate avenues and evaluation tools to support citizen science. From a society angle it is crucial to engage with societal actors in various formats that suit participants and to evaluate two-way learning outcomes as well as to develop the transformative role of science communication. We hope that these key perspectives will promote citizen science progress at the science-society-policy interface. [ABSTRACT FROM AUTHOR]

Citizen science is growing and increasingly realizing its potential in terms of benefiting science and society. However, there are significant barriers to engaging participants in non-Western, non-educated, non-industrialised, non-rich and non-democratic contexts. By reflecting on the experiences of 15 citizen science project coordinators, this paper contributes to the small but growing body of knowledge attempting to identify barriers and opportunities of doing citizen science with marginalised and Indigenous communities. Challenges affecting participation in the analysed projects include issues that range from lack of basic infrastructure and participant safety to unbalanced knowledge hierarchies and data rights. We found that, to overcome these challenges, projects have used several strategies, from promoting decentralized and low-tech solutions to engaging in bottomup actions from a human-rights approach. Finally, our analysis of project impacts supports the idea that doing citizen science with marginalised and Indigenous communities might have a greater impact for participants than for science, as scientific achievements (although valuable) were not among the most important impacts highlighted in terms of project success. By providing stories from the field in a structured way, we aim to guide, to inform, and to inspire other citizen science projects, and to, ultimately, contribute to broader participation in citizen science in the future.

The participation of communities living in high conservation value areas is increasingly valued in conservation science and practice, potentially producing multiple positive impacts on both biodiversity and local people. Here, we discuss important steps for implementing a successful extreme citizen science project, based on four case studies from conservation projects with Pantaneiro fishers living in Brazilian Pantanal wetland, Baka hunter‐gatherers and Fang farmers in lowland wet forest in Cameroon, Maasai pastoralists in Kenya, and Ju|'hoansi rangers living in the semiarid deserts of Namibia. We highlight the need for a high level of trust between the target communities and project developers, communities' right to choose the data they will be collecting, and researchers' openness to include new tools that were not initially planned. By following these steps, conservation scientists can effectively create bottom‐up collaborations with those living on the frontlines of conservation through community‐led extreme citizen science.

Attesting to the powerful capabilities and in technology trends, many scholars envisioned the consolidation of geographic information systems (GIS) into vital tools for disseminating spatial information. GIS are presently used to inform, advise and instruct users in several contexts and to further engage citizens in decision-making processes that can impact and sustain policy development. Interaction with these applications incorporates risk and uncertainty, which have been repeatedly identified as preconditions in nurturing trust perceptions and which instigate a user's decision to rely on a system and act on the provided information. Research studies consistently demonstrated that a trust-oriented interface design can facilitate the development of more trustworthy, mainly e-commerce, systems. Trust in the Web GIS context, despite its significance, has only relatively recently received some attention. A set of human–computer interaction (HCI) user-based studies revealed some Web GIS trustee attributes that influence non-experts' trust beliefs and found that when these are problematic or absent from interface design, users form irrational trust perceptions, which amplifies the risk and may impose dangers to the user. These Web GIS trustee attributes that influence non-experts' trust perceptions are formulated here into a set of trust guidelines. These are then evaluated using the PE-Nuclear tool, a Web GIS application, to inform the public about the site selection of a nuclear waste repository in the United Kingdom. Our preliminary results indicate that the proposed trust guidelines not only support the development of rational trust perceptions that protect non-experts from inappropriate use of Web GIS technology but also contribute towards improving interaction with such applications of public interest issue.

This report aims to enhance our understanding of stakeholder mapping for co-created citizen science initiatives. It presents and discusses findings from an international two-day stakeholder mapping workshop with researchers, event organizers, communication experts, and artists realizing citizen science activities. Participants identified examples of co-creation in their work and mapped stakeholders for three co-creation initiatives from the "Doing It Together Science" project. For each case, we provide an overview of the stakeholder groups involved and the lessons derived from identifying actual and potential stakeholders in different phases of each activity and using different ways for mapping them. We demonstrate that not only stakeholder mapping can be diverse, but it may take different angles depending on the characteristics and project timescales, nevertheless adding significant value to any project. We argue that a better understanding of stakeholder involvement may contribute to more effective stakeholder communication, more successful implementation, and a greater impact for citizen science initiatives.

There is a lack of tools to identify and measure community severance caused by large roads and motorised traffic, despite the evidence of its negative impacts on local communities. This paper reports the development of a suite of tools to measure and value community severance, undertaken as a part of the Street Mobility and Network Accessibility research project. The tools include participatory mapping, spatial analysis, a video survey, street audits, a health and neighbourhood mobility survey, and a valuation tool based on a stated preference survey. They were tested in the area around Finchley Road, a busy arterial road in North London. The study found that Finchley Road is an unpleasant place for pedestrians due to high traffic levels, air and noise pollution, and the lack and poor quality of pedestrian crossing facilities. This has a negative impact on the mobility and accessibility of local residents and, to some extent, on their health and wellbeing. The analysis showed coherence between the findings from the different measurement tools applied individually, but also revealed interconnections between factors which contribute to severance, demonstrating that overall the suite is reliable for assessing community severance in urban areas. Overall, the paper provides a multidisciplinary approach to developing standardised methods to measure a negative impact of transport that is still relatively unknown. [ABSTRACT FROM AUTHOR]

This paper reviews persistent principles of participation processes. On the basis of a review of recent interrogations of the (Public) Participatory Geographic Information Systems (P)PGIS and Volunteered Geographic Information (VGI) approaches, a summary of five prevailing principles in participatory spatial information handling is presented. We investigate these five principles that are common to (P)PGIS and VGI on the basis of a framework of two dimensions that govern the participatory use of spatial information from the perspective of people and society. This framework is presented as a shared perspective of (P)PGIS and VGI and illustrates that, although both share many of these same principles, the ways in which these principles are approached are highly diverse. The paper ends with a future outlook in which we discuss the inter-connected memes of potential technological futures, the signification of localness in ‘local spatial knowledge’, and the ramifications of ethical tenets by which PGIS and VGI can strengthen each other as two sides of the same coin.
