(1) The research presented in this paper aims to study the value attributed to a landscape composition’s visual elements and their overall influence on how they are perceived. The historical and contemporary visual approaches to a landscape constitute its background, for example, geographical, aesthetic, iconographic, phenomenological. (2) The visual assessment method elaborated by the Polish school of landscape architecture is used in the first part of this study. It is built of three steps with corresponding tools: landscape inventory, composition analysis, and evaluation. Moreover, an expert survey is used to complete the study. The work’s novelty is completing the visual approach with an expert inquiry, which aims to solve the subjectivity issue, an inherent visual evaluation controversy. The study area comprises urban and suburban locations from the agglomeration of Poznań, Poland. (3) The research results indicate the significant contribution of three visual elements to the positive assessment of landscape values: greenery, built heritage, and water. The importance of the composition is also demonstrated. (4) The main research findings show that visual evaluation tools should be implemented as part of sustainable spatial planning. Their implementation permits identifying the essential positive value in the existing landscape and creating guidelines for its preservation or enhancement. The article’s significance is the effect of proposing real and possible guidelines to improve the spatial planning policy, making landscape management more sustainable.

(1) Contemporary approaches to sustainable housing design tend to prioritize technological solutions supporting energy efficiency and climate change mitigation. On the contrary, spatial planning of housing estates does not always address all pro-ecological aspects, such as the role of greenery. This research aimed to assess the greenery content and its environmental importance in typical housing districts in the selected study area. (2) The research methodology was based on indicators reflecting the biologically active area ratio, the length of communication routes lined with trees, the tree number per area unit, the tree canopy, and the environmental benefits delivered by the trees. The above indicators allowed us to compare selected models of suburban residential districts typical of specific timeframes. (3) The results indicated that the greenery content and its environmental benefits in suburban districts are decreasing in the study area. Another finding concerned the importance of selecting tree species for their ability to develop a canopy and provide ecosystem services. (4) The proposed methodology, based on inter-related indicators, validly compared the greenery content in the analyzed districts, giving it application value. The problems observed contributed to the proposal of a revision of Poland’s planning practices. Local zoning plans could include streetscape standards, indicating paving solutions and plantings to improve the situation.

The goal of the presented paper is to investigate the potential positive influence that integrating the creative industries within the concept of the creative city can have on the quality of public spaces. The primary supposition is that the concerned idea can formulate an important part of the integrated urban renewal strategy, bringing a response to the declining attractiveness of city centres as well as to the growing outward migration of their inhabitants. Particularly, situating the creative industry plants within an urban context can be considered as an action that can potentially lead to the economic revival of the neglected neighbourhoods and, in consequence, can initiate their effective revitalisation process, leading to the urban landscape’s vital improvement. The concept of such a strategy constitutes of the substantive basis of the design task being commissioned to architecture students at the Poznań University of Technology within the framework of the regular training program. The exercise is to design a creative industry plant within an urban context and it has for its preliminary step to identify a district that requires modernisation. Then, by introducing the heterogeneity of both architecture and use, the students’ projects aim to diversify the functional profile of the neighbourhood as well as to create new public spaces or to revitalise existing ones. Concentrated mainly on the agglomeration of Poznan, the presented paper resumes the outcome of the concerned academic projects and investigates the prospective influence of the concept of creative industries within the creative city on the quality of the urban space.

Urban landscapes have become widespread as urban areas have grown. Studying the urban environment in terms of the ecosystem services provided is a key trend in contemporary science. This article aims to examine selected popular typologies of residential streetscapes in terms of their tree species diversity and the health of their greenery. The method combined an on-site tree inventory and selected indices relevant to the species richness, diversity, evenness, and nativity. Their correlation with the Vegetation Indices (VIs), expressing the health of the greenery and its density, was assessed. The main findings included the identification of positive correlations between the mean VI values and the diversity and evenness indices and a negative correlation with the tree nativity. The diversity and evenness indices could be used to inform landscape planning decisions and to evaluate both existing and projected treescapes. The nativity of trees should not be prioritized during planting selection; rather, the soil and climate conditions should be considered. As a result of this study, a comprehensive framework for assessing the greenness of streetscapes was developed. Its implementation will aid in directing greenery planning in residential areas towards sustainable development and regenerative urbanism.
