Using ICT in the Management of Public Open Space as a Commons

. The chapter de ﬁ nes public open space as a commons and explores innovative ways for its management and sustainable development through the use of new information and communication technologies. It argues that hybrid conglomerates of space and technological interfaces provide this possibility. Section 2 de ﬁ nes common pool resources and discusses issues of its management, before it moves to identify public open space as a commons and to outline key directives for governance. Section 3 outlines the new ICT and considers practices and technologies that can be used in order to enhance community identity, social interaction and user engagement in the governance of the public open space as a commons. Finally, the last section concludes this chapter with some remarks on the conditions under which the hybrid of a public open space with ICT features could be approached as yet another kind of ‘ soft ’ type of common pool resource.


Introduction
organizations have placed emphasis on bottom-up approaches, acknowledging (at least implicitly) that POS is, in essence, a common pool resource (CPR) and as such users, and the public in general, together with the local authorities and other stakeholders, should collectively engage in its management, planning and protection (Fraser et al. 2006;Ernstson et al. 2008).
Contemporary approaches to landscape architecture make an argument for inclusive strategies in urban design placing emphasis on the use of event spaces (Shinew et al. 2004). Recent research in psychology of space reveals how event spaces that are incorporated in natural landscapes and ecosystems create vivid experiences and offer the conditions necessary for creative learning and participatory action. Importantly, these spaces should be seen as parts of, and convergent locales within, an extended network of POS. This network is not fixed, like a snapshot of space at a specific point in time, but rather in a process of continuous development and transformation that is associated with the human activities that it hosts and is contextualised in space. New information and communications technologies (ICT) and the development of visualisation techniques expand human experience to enrich interaction with both people and space (De Souza e Silva and Frith 2012).
This chapter acknowledges that most discussions in the field approach the analysis of common resources with economic terms. The chapter expands its scope beyond urban economics in order to engage in the discourse a more diverse approach to considering POS as CPR. It does so by arguing that spatialised (inter)cultural exchanges of views, habits, occupation patterns and everyday activities can be studied as yet another set of performative capacities of the space as CPR (Gidwani and Baviskar 2011) to be facilitated by ICT. ICT can potentially play an important role in activating POS because the latter is characterised as being more uncertain in valuation than exemplar cases of CPRand therefore more difficult to be measurable or defined by the tools and theories mentioned below. Based on this approach, the chapter defines POS as a commons and explores innovative ways for its management and sustainable development through the use of new ICT. By augmenting the lived experiences of a place, they create a feeling of 'belonging' and 'togetherness' supporting the emergence of common identities (Low et al. 2005) between users. This chapter offers some remarks on the conditions under which the hybrid of a POS with ICT features could be approached as yet another kind of 'soft' type of CPR.

The Common Pool Resources and the Commons
In economics, CPRs refer to goods that at one and the same time, are not amenable to exclusion, but are subject to rivalry; the first signifying the excessive difficulty or cost in excluding people from their appropriation, and the second that use by some compromises the quality and availability of the resource to other potential users. Due to these attributes CPRs are susceptible to overuse, leading to congestion and engendering the progressive depletion, degradation and eventual destruction of the resource; something Hardin (1968) terms "the tragedy of the commons".
In the quest to resolve the quandary and avoid the inevitable tragedy, scholars have suggested the idea of promoting the ethics of stewardship among users in an attempt to encourage more moral and altruistic behaviour patterns that would improve prospects of sustainability (Barclay 2004). Others (e.g. Libecap 2009), in line with Hardin (1968), have emphasized the necessity of designating such resources with clearly defined property rights; thus, endowing the putative 'owners' with the incentive and ability to safeguard the future of these resources in their own interests. Two prospective governance regimes have been proposed to achieve this: the first is privatisation, allowing the attribution of all property rights to individuals (Smith 1981), and the second, nationalisation, involving an empowered regulator (primarily the state) to acquire and enforce all rights regarding the resource (Heilbroner 1974).
However, approaching the problem of governance binarily has attracted significant criticism on the grounds that both proposed solutions (privatization vs. nationalization) result in restricting the rights and actions of the actual users so as to destroy the social relationships and values which characterize a local community (i.e. the social capital), compromising both the long-term sustainability of the community and the effectiveness of the use of the resource. The best-known exponent of this perspective is Elinor Ostrom, the 2009 Nobel laureate in economics, who cites a series of empirical studies from across the world to show how communities are able to manage CPR for themselves, even without the existence of individual property rights (privatization) or an empowered regulatory authority (nationalization) (Ostrom 1990(Ostrom , 1992(Ostrom , 1999. This view raises the possibility of an alternative and more socially acceptable governance regime, the commons, enabling the end users to surmount the problems of collectiveaction to create strong and stable institutions capable of appropriating and managing their CPR in a sustainable manner. These institutions comprise specific social/informal arrangements (rules, norms, practices etc.), which define and allocate rights and obligations among the parties involved within an appropriate framework of legislation that involves mechanisms allowing for effective policing, enforcement and conflict resolution.
Furthermore, this literature (inter alia: Ostrom et al. 1999;Agrawal 2003;Arvanitidis et al. 2015) defines a series of factors shared by all successful collective governance regimes. These elements are categorized under five headings: the first of these concerns the resource itself; the second category delineates the particular characteristics of users: the third focuses on the nature of the relationship existing between the resource itself and its users; the fourth category is concerned with the specifics of the arrangements for governance and the institutional structures created to manage the CPR; and the last of the categories takes into account the external environment and the role of local and central authorities. Put succinctly, the success of a collective governance regime is enhanced with the collective management of the resource by a clearly identifiable community involving interlinked stakeholders able to control the utilization of the CPR in compliance with local needs, preferences, practices and modes of collective action (formal and informal). The essence of this perspective is instrumental approaching the commons from an institutional or economic standpoint by concentrating on the internal nature and structures of governance regimes and emphasizing the primacy of practical issues in long-term CPR management and maintenance (Huron 2015).

The Governance of Public Open Space as a Commons
'Public open space' connotes an all-embracing concept to encompass the various public spaces existing within the urban frame, that are, in general, open, freely accessible and available for use by the population for purposes of recreation, amenity and socialisation. Thus, POS can include such spaces as parks, sports fields, playgrounds, urban squares, plazas, the property of land trusts (school and church yards, vacant plots etc.), the normal roads, pavements, walkways, sidewalks and the whole slew of other public urban spaces. Access to POS is crucial for the well-being of the community by providing a variety of aesthetic, ecological, physical, psychological, and social benefits to residents (CABE space 2004).
POS constitutes a special category of CPR, since excluding the general population is not possible, (non-excludability), but use by some people can diminish the quantity or quality of space available to the rest (rivalry), including non-local visitors and tourists. This degradation of quality and/or quantity for others is a result of the 'saturated nature of cities'; the tendency to house ever larger numbers of people in relatively constricted areas of the urban fabric (Huron 2015). This engenders sufficient pressure on urban land use to force the residents into competing for the resource. Moreover, this situation is exacerbated by a lack of investment in providing and maintaining existing POS by local authorities (because of economic constraints, insufficient political will or administrative problems) thus leading to the deterioration and decline of these spaces. Avoidance of the impending 'tragedy' presaged by this decline necessitates the adoption of new and imaginative solutions for managing this developing situation. The option of a model of collective governance offers a solution.
To facilitate the collective governance of POS as a commons requires an institution of specific arrangements (rules, norms, mechanisms etc.) to control and regulate the use, appropriation and sustainable management of these spaces. To be effective, this would necessitate the joint evolution and development of such arrangements by the local community of users in conjunction with other stakeholders relying on these resources for their well-being. Qualifying for membership in these communities could be formally defined, or, perhaps more convivially, negotiated using ex post criteria, including residence or the agreement of the existing membership. The spectrum of interest groups involved in such a governance regime perform differing roles and have different rights (defined de jure or de facto) without these being either transferable or exclusive. Here, it is of crucial importance to underline that the practicalities of managing such resources is a critical element predicating the success of such governance regimes, with this more dependent on providing a framework for the allocation and enforcement of these diverse rights to the involved parties rather than on land ownership per se . The manner of structuring and implementing these rights has a crucial impact on the quality and quantity of the resulting benefits, and thus on the incentives to sustain the arrangements for the resource .
Our ability, as a community, for communication, becoming involved, entertaining ourselves, even for working have been, potentially at least, enormously enhanced over the last decade or so by innovations in ICT (McCullough 2007). The advent of wireless networks, smart devices, on line apps, services and cloud technology have provided previously undreamt-of facilities for becoming informed and acting and engaging with other people and space. The new possibilities for social interaction, networking, and collaboration, offering, at least in theory, the formation and function of new communities of shared interest. This constitutes something with major implications for new means of public participation and collective action (Sheller 2004;Hampton et al. 2010).
In sum, such new ICT opportunities enable a whole new gamut of innovative means for the management of public spaces and the sustainability of collective governance. The following section is an attempt to chart these technologies and explore the potential of their relevance to the management of POS as a commons.

Public Open Space, Humans and Information and Communication Technologies
POS is not simply physical space (Carr et al. 1993); it is rather an assemblage, a synthesis, of space and narratives (stories) (DeLanda 2006). These narratives (Miles 2016) are mechanisms that enable indeterminate interactions between users (citizens) and resources (space). This scheme applies to complex urban environments where layers of human activity and the everyday life contribute to the experience of organically associated urban palimpsests. The affordances of this symbiosis, of plural narratives and spaces, contribute to the sustainable management of the city as a whole due to their impact on the social sustainability of the communities that inhabit the city. Social sustainability and resilience can be explored through socio-ecological systems (SES) that offer a base to analyse interaction between humans and nature in different scales. Knowledge between social and environmental dynamics is essential for the development of SES (Cote and Nightingale 2011). Ongoing symbiosis between citizens and physical environment contributes narratives. Opportunities to utilize them in dynamic management is a vehicle to develop the cyberpark concept. Firstly, artful inquiries are used to recognize and communicate citizens´experiences and narratives associated to specific spaces, secondly this process offers the grounds for critical coreflection, through which key implications are identified and the initial conceptualization if ICT tools is constructed. This process is a driver to support citizens' agency in social sustainability contributing also to the ecological and economical sustainability of the space. Human adaptation to SES is continuously promoted by sharing knowledge and cultural exchange whilst the dialogue with POS management creates novel and resilient management (Suomalainen et al. 2017).
Arguably there is evidence of user segmentation of POS (Heritage Lottery Fund 2016), and in principle ICT add a new layer of interfaceand therefore, ICT represent yet another mediation between space and its users -but this chapter argues for the conditions under which ICT can be used productively for enhancing a POS. These include mostly the parameters of a new way of asynchronous dialogue and information transmission that is performed not only between users, i.e., social aspects of spatial occupancy (Marušić 2010) but also between the POS and its users. Ward (2014) highlights that the "regulation of access and use of resources are of central concern to the maintenance and sustainability of the commons", suggesting that the latter involve conflict between individuals, social classes and communities. Collective uses of CPR are considered as an added value of a common 'stage' that hosts dialogue, communication and shared activities. In our case ICT render the access to the resources associated with a POS even more sensitive to regulation. This chapter though is occupied with this kind of POS that is characterised as open, inclusive, unplanned, of uncertain function, or lightly regulated (Sennett 2006). Williams et al. (2009) suggest that ICT can promote and facilitate these collective uses through digital media and platforms (such as wikis) that enable collective management and valuation of planning solutions. The chapter argues that in addition to interference between users of POS and physical access to its resources by means of promoting and managing activities that are typically highlighted by the conviviality of POS, such as leisure, sports, contemplation, meeting and co-presence, as well as open air museum, cinema, street theatre and other performances (Low et al. 2005), ICT could potentially contribute greatly to interpretation and inference of meanings through space occupancy. These data when managed openly, freely and creatively can facilitate engagement of users with the management of the resources of the space, and by doing so to add value to the POS towards its integration into a larger network of CPR (Taplin et al. 2002).
The appropriate use of ICT reintroduces physical space into the digital stage of the contemporary technologically-enabled social network of the cities (Graham 2005). This hybrid of spaces brings back to the cityscapes the micro-and nano-scales of relations that enable place-making and promote social interaction and belonging. Specifically, the framework of this approach involves the enabling of smart citizenship initiatives by means of: • Citizen engagement in POS management through participatory design practices and ICT, since a sense of common purpose is induced typically by opportunities of or threats to change things (Schmelzkopf 1995) and this commoning is a meaningful performance of a POS; • Citizen participation in urban monitoring and observation (congestion, noise, pollution); • Exploitation of ICT and geo-referenced data for urban reactivation planning and policy making concerning important sites that have been neglected; cultural promotion and give prominence to less popular tourist destinations (Dodge and Kitchin 2007).
The above areas of contribution are empowered by the capacity of said tools and technological solutions to facilitate, and sometimes accelerate, the self-organisation of thematic communities that form groups around topics and sites of interest, and actively contribute relevant knowledge to the associated network. In this context the exploitation of ICT can disrupt typical considerations regarding accessibility of urban commons and equality of usage. As presented in Chapter 5.5, ICT integration can be expanded in order to reach larger audiences than the stakeholders of a POS, and enable even remote users to contribute knowledge. These crowdsourcing platforms can provide a stage for intercultural dialogue and informal contributions without the direct control/regulation of information exchange by intermediate stakeholders (Paulos et al. 2008).
Using the capacity of ICT tools in data transfer and communication of information of technologies such as GPS, RFID, Bluetooth, wireless beacons, surround sound, augmented reality and mixed reality, can enrich user experience of POS as urban commons, by means of interaction. This becomes possible by the likes of blogs, mobile apps for video and photo sharing, and other Web 2.0 applications (O'Reilly and Battelle 2009) that can enhance the degree of personalisation, openness and participation of users and citizens in the management of the POS (Rheingold 2001). Their engagement through activism, participation and smart citizenship is further facilitated not only by the operation of large-scale screens and projections in space that are open to everyone (Brignull and Rogers 2003) but mostly by developing virtual communities, which can be established by the technological interfaces above (Boyer 1996).

Open-Ended Creative Practices of Accessing Public Data
Digital technologies stage an interface that conditionally facilitates engagement between individuals and space (Calabrese 2009;Artopoulos 2012). This approach to technology as an interface between individuals (urban citizens) that are strangers (Jacobs 1961) and spaces that are occupied in habitual ways is based on the premise that rites and habits generate feelings of familiarity and in doing so contribute to the establishment of a sense of connection and belonging. Relevant discourse has been largely occupied for decades with the impact of ICT on both the erosion of social relationships and the capacity for intervention on inclusivity of POS, as well as on intensifying the disengagement of users that are already excluded (Barlas and Çalişkan 2006;Graham and Marvin 2001;Servon and Nelson 2001).
Nevertheless, there are many examples that showcase the contrary, with the recent cases of using social media for the communication of virtual communities of not only activists, but also of producers, sellers etc., and socially responsible practices such as carrotmob.org (2010), or the so-called 'civic hacking' (mySociety.org, 2010). Distinct from their exploitation as a tool for social segregation, there are opportunities for ICT to be used in a more inclusive way (Horelli and Kaaja 2002), and this chapter aspires to contribute to this end. This section suggests that the following steps of user engagement in co-management and co-creation (Figs. 1 and 2) could benefit from the use of ICT: • Mapping of assets by means of spatially-distributed individual narratives, collective meanings and geo-location of stories; • Visualisation of real-time (observation) data, and tools for user co-development of visualisation workflows that would be meaningful to them; • Open-ended practices of data interpretation and enabling users to have meaningful access to real-time data.
These parameters and aspects of ICT are necessary for software and digital platforms to be explored as inclusive mechanisms for users to access POS in positive ways, e.g., in order to increase the openness of POS to variation and multiplicity (Stavrides 2016). This understanding of ICT-enabled POS builds on the use of a cybernetic electronic infrastructure (Batty 2013) that facilitates the engagement of the users in new idiomatic and localized conditions of urban commons (Artopoulos and Charalambous 2017). 'Devices' of engagement sourced from narrative-based cultural and creative industries, such as an 'exploration for learning' incentive, when integrated in communication interfaces, can serve as a vehicle to empower users. In this approach visitors and citizens of the city, as well individuals and communities that may be excluded could be enabled to raise their voice and participate in the future development of the POS (Páez and Darren 2005). These technological solutions are built on conceptual devices for individuals' entanglement with space through goal-oriented activities, such as gamification (Atkinson and Willis 2009), playful engagement and serendipity (Wetzel et al. 2011).
Contextualised in societal challenges for the social resilience of urban space, these approaches differ from typical, corporate visions of smart cities. The former differs from the latter, as it interprets the user of ICT-networked information as a consumer. Current corporate visions of smart cities focus on data-consumption and the commodification of access to the big-data of the city (Schnitzer 2013), and value the citizens' well-being by the ease of access to such resources as public transport, infrastructure and digital media (Peugeot 2013). These visions of smart cities produce a false sense of accessibility to what is actually a representation of the city as a (cybernetic) machine, and the notion of acquiring a lightweight control over the city's noninterpretable complexity.
Alternatively, the approaches to ICT-augmented POS presented in the chapter are concerned with issues of equal opportunities in accessing 'other' types of urban commons (Bollier and Helfrich 2015), such as urban agriculture and community gardens, timebanks and telecommunications infrastructures (e.g., Guifi.net), which are self-regulated via collectives, fabrication labs and hackathons (Rodotá 2012). Annotating physical space with digital representations of ideas, feelings, thoughts, memories and informal narratives enables the observation, communication and visualisation of individual tolerance, contested realities and exchange of insights through space (i.e., resource) exploration.
In the context of this chapter, CPR are understood in a more open definition that is inclusive of interwoven networks of natural and social resources as well as of inhabitant's cultural production mechanisms (Patterson 2010), such as ecological zones and public spaces, air, water and infrastructure management systems, odours, and built heritage. The latter is here defined as anything that helps us collectively understand our present and speculate about our future conditions (http://www.heritageexchange.co.uk/, 2014). These opportunities for habitual interaction and familiar encounters are arguably limited in contemporary urban everyday life (Gilroy 2004). The ICT solutions presented are facing exactly this challenge as they aim to augment and multiply, in a pluralistic way, these opportunities for interaction across space and time, in the virtual projection of plural conditions and times (e.g., historical events) on the physical space of POS. Finally, another important aspect of the presented approach regards the capacity of said ICT tools in offering to citizens new opportunities for temporal personalisation of POS. This chapter suggests that the use of ICT on POS should allow for the interpretation of observation data by their users themselves, through the appropriate visualisation interfaces. The chapter argues that associating activities that are typically hosted by POS with individual narratives and meanings introduces additional values to a POS which increase civic participation and could potentially benefit the function of the larger network of POS in the city.

Overview and Conclusions
POS constitutes an urban commons that faces serious risk of decline (both in terms of quality and quantity), and even destruction (the so-called "tragedy of the commons"). This eventually leads to a degraded urban environment and a disadvantaged urban community. The conventional CPR literature prescribes as appropriate solutions to the problem either privatization or nationalization of the resource. However, many countries exhibit a number of characteristics (e.g., not clearly defined private property rights on specific resources, rigid and bureaucratic institutions with deficient policing and enforcement mechanisms, limited financial capability of local authorities, etc.), which preclude successful implementation of such governance structures. On the other hand, as Elinor Ostrom and other scholars have established, the stakeholders themselves can collectively develop institutional arrangements (more socially acceptable and with lower implementation costs), which enable them to ensure proper use and longevity of the common pool resource. The new mobile ICT, by enhancing human connectivity and enriching interaction, enable the reconfiguration of urban spatiality and of public spaces, and as a consequence allow for greater degree of creativity and freedom in the management, interpretation and valuation of the POS by its users through participation and engagement.
Contributing to this literature, the chapter has explored issues of data accessibility, data sharing, interoperability and mostly interpretationand to this end data visualisationthat are now deemed prerequisites for the inclusive operation of ICT in POS, in order for the latter to be considered part of the network of CPR. Given that technological platforms and ICT are open to, and accessible by, all users, their exploitation through accessing content and exchanging information could expand the capacity of those areas in staging intercultural dialogue. This dynamic operation contextualises the use of ICT in a broader effort that attempts to bridge the gap between ecological and civic commons (Gidwani and Baviskar 2011). All these are aspects of interacting with a POS that can be valued for its conditionally positive impact to the space by tacitly promoting exchanges that grow new relations with the space and its users. In this context the chapter approached the hybrid of the POS and embedded ICT solutions as a seemingly indivisible new condition of urban commons in contemporary cities that is capable of contributing, under the right circumstances, to the resilience of the urban environment.
