In recent years, nature-based solutions have been increasingly promoted as a climate change adaptation instrument, strongly advocated to be co-created. Achieving clear, coherent, and ambitious urban greening strategies, embedded in urban planning and developed in a co-creative, participatory and inclusive manner, is highly challenging within the EU enlargement context. In this article, such challenges are studied through two recent urban development initiatives in Belgrade, the Capital of Serbia: the first initiative focuses on planning the new Linear Park, within the framework of the CLEVER Cities Horizon 2020 project; the second initiative envisages the transformation of the privatised Avala Film Complex in the Košutnjak Urban Forest, primarily led by private interests but supported by the local authorities. The multiple-case study research method is applied, with an exploratory purpose and as a basis for potential future research on evaluation of co-creation processes for NBS implementation. The theoretical basis of this article is founded in the research on sustainability transitions, focusing on multi-level perspective (MLP) framework. The urban planning system in Belgrade and Serbia is observed as a socio-technical regime of the MLP. In such framework, we recognize co-creative planning of the Linear Park as a niche innovation. We interpret opposition towards planning of the Avala Film Complex as escalation, or an extreme element of the socio-technical landscape, comprised of civic unrests and political tensions on one side, combined with the climate crisis and excessive pollution on the other side. Moreover, the article examines informal urban planning instruments that can be implemented by the practitioners of niche innovations, that could support urban planners and NBS advocates in the Serbian and EU enlargement contexts to face the challenges of motivating all stakeholders to proactively, constructively and appropriately engage in co-creation.

The idea that multifunctional open spaces support sustainable urban development has been widely accepted in theory and intensively used in practice of urban planning and design. It is based on the assumption that multifunctional spaces bring a wider spectrum of environmental, social and economic benefits to urban areas. And yet, multifunctionality of space is still a vague and diffuse concept that needs further clarifications. Besides that, different academic disciplines understand and use this concept in different ways. This makes the application of the concept difficult to assess and manage in relation to different aspects of urban sustainability. Through the literature review, this paper analyses and compares how the concept of multifunctionality is used in various spatial disciplines (urban planning and design, landscape architecture) in order to better understand and relate its different dimensions, applications and expected benefits for sustainable development. Based on this, a new, relational and multidimensional conceptualisation of the multifunctionality of public open spaces is proposed for analysis and assessment of urban design solutions. It is further applied and discussed in relation to students projects from ?Ecological urban design studio? from the University of Belgrade Faculty of Architecture, as visions for development of multifunctional public open spaces in modernist mass housing area of ?Sava Blocks? in New Belgrade, Serbia.

Using heritage as a cultural artifact in city development is not new, but little has been explored about how urban heritage can be utilized as new generative value and a new planning instrument for the revival of cities. The purpose of this paper is to show the creative and the generative use of urban heritage, both for the extension of cultural and tourist offer of the city and for the improvement of the quality of life in physical, social and economic terms for the community. The case study method was used for the adaptive reuse of projects for heritage buildings and urban revival in Kikinda. We argue that urban heritage has to be used, bearing in mind its spatial, economic and social sustainability aspects, and become a generator of urban revival. We go beyond recognition of the value of heritage as a cultural artifact that should solely be preserved and used as a static element in urban development, and view it more as a dynamic asset for city revival processes. We found that for the heritage nodes to be utilized as the new generative value for the revival of cities, they have to be perceived from the network perspective, thus influencing the urban environment in a sustainable way.

The 20th century brought about major social challenges related to civil and human rights, triggering changes in urban environments and gradually adjusting the spatial and functional performances of cities to the needs of all users. In this article, the concept of Universal Urban Design (i.e., “Design for All”) is regarded as a sustainable placemaking process which enables the higher accessibility and usability of cities for all people, regardless of their age or (dis)abilities. The pilot project “Creating Accessible Pedestrian Corridors by the Limitless GIS Application” conduced in Serbia from 2017 to 2019 by the Faculty of Architecture at the University of Belgrade and the Non-Governmental Organization (NGO) Limitless proposes an innovative approach to urban design. Based on information and communication technology (ICT) adaptation, it is focused on the alternative concept-design of buildings, provision of ICT-based infrastructure, socioeconomic integration of all users, and ultimately on overall urban sustainability. The main outcome of the project was the development of a Geographic Information System (GIS) android application and an e-platform for adaptive placemaking. The project also provides a set of accessibility criteria based on Universal Urban Design, criteria that enable the mapping of locations based on the type of use, a set of recommendations for identified problems, as well as a brief analysis of the latest technological solutions for overcoming detected physical barriers. The Limitless GIS android application differs from the existing ones since it primarily identifies two target groups: (1) people with disabilities who could upload necessary data by established criteria; and (2) employees in the public sector (city authorities and municipalities) in charge of planning alternative routes and setting priorities and investment costs based on the identified problems. Pilot results of the project have revealed that in the current Serbian practice, there is still a lack of planned, consistent and continuous movement routes in urban areas. Terrain configuration represents a serious limitation for people with disabilities, while lifting platforms are recognized as a better solution than ramps (both for paraplegics and quadriplegics), due to their higher efficiency and minimized spatial requirements. Therefore, the android application and e-platform presented in this article contribute to the detection of actual problems at the local level as well as to the overall improvement of planning/design practice in Serbian cities.

The growing perception of heritage as a public commodity encourages rural communities to recognize their natural and cultural heritage as a potential for tourism development. This creates the need for an appropriate presentation of heritage sites that ensures that their cultural and natural assets are appreciated and protected. “Negotinske pivnice” are cultural heritage sites in Serbia, nominated for the UNESCO World Heritage List. They are architectural complexes of wine cellars in rural region with a long tradition in wine production and industry and are unique in terms of their settlement structure. This emphasizes the spatial dimension of their interpretation and presentation, and highlights the importance of urban design for their sustainable use for tourism. Based on understanding urban design both as a process and a product, and cultural heritage site as a place, we argue that participatory urban design contributes to appropriate heritage presentation by widening design knowledge base to include local communities’ lay knowledge. Following the case study methodology, we explored the relationships between participatory process, the knowledge gained, and urban design solutions for presentation of cultural heritage sites as living places in “Wine Cellars of Negotin Participatory Urban Design” project. The research reveals that the wider knowledge base affects urban design at both strategic and project levels and sets the grounds for diverse presentation forms through which harmonization of heritage protection and touristic presentation is possible.

The influence of place branding in urban development has more importance than ever. Nevertheless, little attention is given to how place branding strategies are interrelated with planning, especially in post-socialist urban development. The purpose of this paper is to critically explore experimental educational projects conducted through cooperation between academia and local governments in Serbia, perceived as a simulation of strategic planning and place branding. We argue that educational projects hold power to create additional value in place and contribute to place branding by using a variety of planning and design instruments as a means of transformative spatial and social change both for communities and students as future planners. This paper uses theoretical exploration to develop reflective structural elements and a set of criteria essential to interlink strategic planning and place branding, thus providing a unique apparatus for the evaluation of educational projects. By emphasizing the possibilities and limitations of educational projects, the paper contributes to the theoretical advancement of place branding and strategic planning interlink and sheds light on the effects that those projects may have on spatial development and governance of the territory.
