The perception of urban greenery is determined by many aspects, including the personal security of different groups of city dwellers. The objective of this study was to investigate if there are differences between the sense of security of older adults and other groups of urban park users, and which factors play an important role in the evaluation of personal security and thus determine the use (or not) of parks. A survey questionnaire was administrated to a sample of randomly selected park users in Poland (n = 394), including seniors (s = 69). The results show statistically significant differences in security perception between respondents under the age of 60 and those over the age of 60 in the case of all questioned factors. At the same time, all of them are important for a sense of security in older adults. This knowledge is crucial for designing more inclusive and age-friendly urban parks, which should meet the needs and expectations of older adults and encourage them to engage in more activity.

Perceptions of personal security significantly affect human behaviour in geographical environments. The way public places are perceived determines their utilization and their attractiveness among urban residents. Various methods have been applied to study perceptions of security and the environmental factors associated with it. Urban environments comprise a variety of places, including those with urban greenery. The main objective of this chapter is to explore and compare different participatory research methods focused on analysing the factors that influence perceptions of security in urban parks, and to explore their potential for placemaking processes. This overview is illustrated with three examples from the Czech Republic, Poland and the United Kingdom. The first case study explores perceptions of topophobia in places with greenery and parks in the town of Šternberk (Czech Republic). It employs cognitive mapping by a selection of local residents, and results are visualized on (by the help of) semantic maps. The second case study explores the extent to which park infrastructure and maintenance levels affect perceived security in urban parks in Warsaw (Poland). The third case study uses data recorded from the crowdsourcing Place Pulse project to analyse the spatial association between perceived security and the tree canopy (including trees in urban parks but also in the streets) in London (United Kingdom). The relation between greenery and perceived safety may be context-dependent and vary across areas. All three participatory research methods use residents’ knowledge based on primary data gathering and digitization and as such offer practical tools for placemaking.

The geographical presentation of various data on the spatial functioning of society has been present in fields such as social policy and security for almost 200 years. New technologies, in particular computerization and the GIS tool, not only make the mapping of social problems or security threats more accurate, but also allow for the interactive creation of those maps by society and public institutions. This article is a qualitative analysis of solutions used in the Silesian Voivodeship, a region of Poland with a highly specific nature and density in terms of the problems discussed. The tools presented, including a “National Map of Security Threats” and “Maps of Social Problems and Resources in the Local Environment”, demonstrate—apart from their obvious benefits, such as increasing public awareness of threats and enhancing cooperation between society and public institutions in combatting them—the challenges and problems that these solutions bring and may also create in the future.

The National Map of Security Threats (NMST) implemented in Poland in 2016 is a GIS-based tool for digital crime and threat mapping involving citizens in the processes of shaping local security by reporting hazards in their neighbourhood (volunteered geographic information). The map—open for external users—is a source of information about common threats to the safety of human life and health, property, and public order, taking into account their spatial distribution, in the opinion of its users. Among 26 reportable hazards, there are categories related to (1) Traffic, (2) Greenery, (3) Water, (4) Demoralisation and Vandalism, (5) Poverty, (6) Alcohol and Drugs, and (7) Animals. The study aims to investigate which threats reported by citizens are the most represented on the NMST. The study covered data collected based on public access to the map in the period from January–December 2022. The analysis of the results allowed us to conclude that the most common threats belong to the following categories: (1) Traffic, (2) Alcohol and Drugs, and (3) Greenery. While the first two categories are not a surprise for researchers, and their importance is confirmed by other studies, the category of Greenery—its condition, damage, etc.—becomes more and more important, which was not confirmed in previous studies. Recognizing this is crucial to support processes of planning and designing more secure public spaces.

Citizen participation today needs to be understood as both an empowerment practice to create urban futures as well as the perpetuation of entrepreneurial and neoliberal modes of planning. The exponential progress of technologies and the digitalisation of everyday life have led to a surge of innovation. Since hybridity has become a key factor, citizen participation now involves citizens and governments meeting online and offline in a multi-stakeholder setting to plan the city in parallel layers, often according to controversial or even contradictory logic (Horelli et al., 2015). As digital citizen participation opens up new tools and means to mobilise people and shape urban futures, this chapter analyses these new aspects through the categories of top-down/bottom-up participation as well as formal/informal practices. Using four case studies comparatively, our aim with this chapter is to find a new theoretical basis and contextualisation for digital citizen participation. The case studies are situated across Europe and North America: we study participatory budgeting in Helsinki, digitalising citizen participation in Lubbock, Texas, the National Map of Security Threats in Poland, and digital placemaking by a grassroots movement in an urban planning participation process in Zürich, Switzerland. The findings of the article show that (1) digital citizen participation fosters novel multi-actor networks negotiating governance of the urban space, (2) studies of citizen participation need to acknowledge the multi-layered hybridity and (3) new modes of governance enable novel senses of informality in participation.
