Wood in general is a traditional building material in Northern Europe including Latvia and other Baltic countries, but nowadays it is used less in Latvia than in other EU countries. There are many forests in Latvia and a well-developed timber industry. Latvian society is enthusiastic about eco-materials, and qualified architects and engineers are ready to work with timber structures. However, wood is mainly used for small buildings and residential construction, but minimally in public and multi-apartment buildings. The study was carried out among architects and other stakeholders in Latvia to analyze their impact on the selection of building material. Thirty-eight interviews were conducted, questionnaire among 73 respondents carried out, and discussion in a focus group was held to find out the main reason and barriers for using wood for buildings in Latvia less than in other EU countries. During the research the main influencing factors for choosing wood constructions were identified and seven main barriers formulated. The study results were compared with the results of similar studies in other countries. Two of the seven barriers in Latvia – stereotypes and legislation – were not mentioned in other studies, nevertheless, these are the most frequently mentioned obstacles in the Latvian case.

The active use of modern technology has affected the relationship between people and place. The “digital environment” and the “digital community” are becoming an increasingly important factor in people’s daily life, leading to a loss of belonging to a place, an entire neighbourhood, and a community. In the long run, this poses risks to the unification of values and the loss of identity. In this context, the involvement of the local community in the identification and preservation of historical heritage and defining the specific values of each site is particularly important. Thus, both the attraction of the local community to specific places and the revealed potential of local tourism are promoted. Digital placemaking enters urban regeneration as a logical approach to mixing digital and physical environments and involving the local community. Several GIS-based platforms and other tools are used to identify heritage values, both tangible and intangible. Although digital placemaking is emerging worldwide, its manifestations are closely related to specific local circumstances. The article focuses on the key characteristics and configurations of the digital placemaking tools within particular communities. The study tests digital placemaking practice in the historical districts of three cities: Taipei (Taiwan), Riga (Latvia), and Kaunas (Lithuania).

Urban regeneration, which includes renovation of decaying urban structures as well as renovation of dilapidated buildings, is an important economic, aesthetic and cultural factor for sustainable development planning worldwide. The revitalization of urban structures is a complex challenge, influenced by various interdisciplinary aspects, like urban socio-economic development, integrated transport and mobility solutions and others. And it requires involvement of different stakeholders at different levels in identifying and finding solutions. Technological innovations offer a variety of digital tools to address modern urban governance and modelling issues, identifying problem areas with public involvement and participation that allow relevant services to respond quickly, thus improving the urban environment and the quality of life of people. With the help of digital tools, it is also possible to promote the availability of public services, model and forecast environmental risks, as well as perform other functions integral to the organization and management of modern society. However, the wide range of these tools and their mutually asynchronous use often make it difficult to choose the right tool, thus creating the risk of fragmented implementation. The aim of this paper is to propose theoretical approach for modelling of complex interactions affecting urban regeneration as well as summarize and systematize the existing digital information tools which might empower the process of regeneration. The analysis of the use and impact of digital and smart tools allows to identify urban problems, as well as to outline ways to solve them. The results of the research will form the basis for further research stages.

The renewal of urban areas by developing green open spaces increases the overall quality of life and helps to reduce social exclusion. Urban green open space can help to constitute a framework where urban society and culture can develop, and to increase identity and a sense of community. It can be used to provide a ground for education and raise an awareness of the way ecosystems function and how urban functions can be integrated into the natural system. Despite the known socio-economic benefits resulting from it, considerations regarding sustainable land use planning often occupy a secondary role when designing city quarters. There exist many pressures – essentially market-related and driven by short-term thinking – for unsustainable development. Housing ownership reform, carrying out denationalization and privatization, along with a core capital for many inhabitants has also created a range of problems – one of them: as a result of denationalisation of land properties, when the land in large-scale residential districts was returned to the previous owners and then provided as the minimum required land to the privatised buildings, the original spatial composition of districts was completely destroyed, creating a legal basis for new construction in large-scale residential districts.

Urban regeneration with a view to efficient use of urban areas has been a strategy for urban development for decades. Densification is used as a planning approach to promote the implementation of the compact city model and to discourage urban sprawl. The central parts of the city are usually of high density, so the areas outside the city’s historic centre are seen as potential sites for urban densification. In many European cities large-scale residential areas built after the Second World War occupy a significant part of the territory outside of the city’s historic centres. Today, these housing areas are in most cases sleeping areas with great potential for development. Densification of urban areas outside of urban nuclei is not an easy task, and deals with a whole series of challenges. The paper examines the existing approaches focused on densification in large housing estates. In order to define the typical challenges of this process, the examples of infill developments in large housing area Imanta in Riga are analysed. The analysis of infill development in Imanta showed four possible approaches. Some approaches contribute to the improvement of public space for neighbourhood inhabitants in general, still some approaches tend to isolate the new development and inhabitants from the surrounding territory.

The increasing complexity of urban regeneration issues has recently made multi-stakeholder collaboration an important part to solve policy problems. While residents form an important part in a variety of collaborative governance processes, approaches used are often criticized as too formal, and lacking more inclusive participation. Therefore, new informal mechanisms of collaboration are sought, to ensure a more effective engagement and representation of population groups. Although community-led participation is the approach that leads to a more effective collaborative process, issues of power and inequality are a challenge in many places in planning practice [13]. Ways of civic empowerment, communication, and negotiation provide participants with transformative learning opportunities so that not only their arguments change but also the participants of the participation process themselves [6]. In order to test urban development ideas, the notion of "urban experiment" has been developed in recent years as a recognized and effective approach. The urban environment is viewed as a creative laboratory for testing the implementation of diverse initiatives and innovations [8]. The inner-city neighbourhoods in many cities are struggling to ensure vitality and liveability, thus these areas often represent a widespread location of urban experiments. In addition to these questions, the problem of community representation manifests itself in many inner cities. The potential to transform city centre streets and vacant areas into user-friendly urban spaces and the impact of those transformations on the city’s livability were recently tested by Riga municipality. Urban experiments varied in scale and form, resulting in street pedestrianization, urban gardens, and other temporary initiatives, which allowed more space for walking and cycling, street sales, social events and other activities. Thus, the aim of this article is to explore processes of testbed planning with regard to the role of community participation in the designing, implementing, and analysing phases of the experiment. After presenting the findings, the article concludes with a discussion on factors that influence public participation in collaborative governance including communication, the balance of interests, and the degree of resident involvement in decision-making.
