The purpose of this study is to examine the impact of public open spaces (POS) on host community in Kano Metropolis.

Two sets of questionnaires and participant observation were used to collect data for the study. The questionnaires were used to elicit information on the socioeconomic characteristics of residents and users, a total of 140 residents and 70 users were selected for the study using random sampling without replacement.

Findings revealed majority of the residents earn above 25,000 naira monthly with a percentage of 32.85% while patrons were dominated by respondents that earn below 25,000 monthly. Also, majority of the respondents (94%) have received formal education. Further findings revealed that POS in Kano Metropolis plays an important role in encouraging recreational activities; although some of the open spaces were to some extent declined, the study confirmed the existence of 28 open spaces from the underlying 35 POS within the metropolis. It is noteworthy to note that males were found to be more (80.9%) among users of all the open spaces in the study area with the least participation from their female counterparts. The study further revealed that the adverse effects faced by users of POS and members of the host communities comprised of lack of facilities within the open space, inadequate security, inadequate lighting, lack of vegetation cover, poor parking spaces, breaching the public peace while the residents perceived the open space as means of obstruction of public facilities, causes accident, causes traffic congestion, environmental pollution, increase in accident, obstruction of public facilities, increased accident, degrades the environment, breaching of public peace, traffic congestion and obstruction of public facilities.

The outcome of the study will raise the awareness of the people on the importance, conditions of facilities and the impact associated with the usage of open spaces on adjoining residence. It will also inform stakeholders the modalities to prevent further decline or conversation of open space to other land use and promote proper management of open space facilities and mitigate its likely negative impact on the environment. This will contribute toward achieving Sustainable Development Goal 11.

Visual aesthetics are a vital aspect of environmental quality. The objective of this study is to demonstrate the implementation of visibility analysis and visual quality standards on a campus to enhance productivity and effectiveness.

This study has identified the most crucial and valuable metrics for evaluating the visual quality of open spaces through an analysis of theoretical foundations and relevant background information. To achieve research goal, a multi-method approach was employed, incorporating a survey, user satisfaction ratings and ISOVIST simulation techniques. Specifically, this study focused on assessing the quality of open spaces in three open areas located on the campus of the Iran University of Science and Technology.

Based on the study’s findings, the most significant factors that students considered when evaluating the visual quality of open spaces on the Iran University of Science and Technology campus were green areas, gathering spaces and architectural elements such as furniture, color and texture. Among the three open areas examined, “Open Space One” was identified as the most satisfactory location for students. According to the study, “sensory richness,” “complexity” and “mystery” were significant indicators of students' satisfaction in this area. This area also had the widest radius and field of view feasible, which gave it a feeling of openness and spaciousness.

This study explores the influence of students' experiences, behavioral patterns and visual analyses on their use of open spaces on university campuses, with a focus on the Iran University of Science and Technology. By assessing students' satisfaction levels with these spaces, this research provides valuable insights that can guide the initial analysis stage before the design process and facilitate design optimization during the development stages. The results highlight the importance of considering user experiences and visual analysis when planning and creating open spaces on university campuses.

Highlights

1. Conducting an initial analysis before developing a design plan can be very helpful in understanding how users think and behave.

2. The three criteria of visual quality that have the strongest correlation with students' satisfaction with “open space” are “mystery,” “sensory richness” and “complexity.”

3. Two factors, namely the “radius of vision” and the “area” index, significantly influence students' satisfaction with open spaces.

4. Outdoor designers should incorporate “green space” and “gathering spaces” into their designs since the presence of these is effective in attracting and satisfying students.

5. The number of people using an open space has little to do with how satisfied students are with it.

6. Half of the students use open areas between 11:00 and 14:00, so the provision of “canopy” and “shelter” in these spaces is essential.

Current policies and research on carbon emissions focus on operational emission but overlook the importance of embodied and user-transport emissions in residential buildings. This study built a comprehensive framework to assess the impact of life-cycle carbon emissions on different in-building open public spaces (open roof, open vertical garden, and open ground floor) in affordable housing.

A parametric model of a typical affordable housing building in Shanghai, China was constructed and 36 variations of open public spaces studied. Embodied, operational, and user-transport carbon emissions were quantified over 50 years.

The results show that the life-cycle carbon emissions decrease with the application of the open public space. In addition, the paper found that the carbon reduction due to user transport is seven times higher than the carbon increment due to construction and over long-term operation.

This paper provides quantitative evidence for carbon emissions and in-building open public spaces, and the authors suggest taking multiple aspects into account in addition to the structure of the building is crucial to sustainable building development.

The urban development within the Ottoman Empire saw two major zones distinguished in the city – the residential area (mahala) and the public core (carsija). The same model was applied to Bosnia and Herzegovina during the Ottoman period (15–19th centuries). This paper focuses on the historic core of Sarajevo, known as Bascarsija, developed during the Ottoman period in Bosnia. This article aims to define the qualities of open spaces in Bascarsija, particularly its physical attributes, sensory experience and activities.

Firstly, it is important to understand the development of historic urban tissue. A transect walk across Bascarsija was used to identify several categories of public space. Following this, draws on theories of the qualities of space, open spaces in Bascarsija were systematically analyzed.

Types of open space were distinguished according to their purposes and relationships with their surroundings. For each type, it was possible to define physical attributes, as a reflection of the applied form, scale, relationship to nature, hierarchy (dominance) and local texture; activities, which depend on the current function and attractiveness; and sensory experience derived from the subjective experience of users which rely on current functions and physical forms.

The qualities of open space in Bascarsija are distinguished, highlighting the importance of such places. This paper contributes to a comprehensive understanding of the image of the place and values of the historic core of Bascarsija, laying the groundwork for further research and urban interventions.

This paper aims to work toward a new approach in providing green open spaces in the middle of urban land in Indonesia that has been densely built up and on it has attached land rights. An approach is needed through a specific spatial policy that contains zoning regulations for the provision of public green open spaces on top of residential houses built on the green zoning plans.

This approach considers an interconnected ecological holistic approach, as previously existing regulations have not normatively identified the green open space as an ecological landscape consisting of blue open spaces and several objects that function as green open spaces.

Indonesia in terms of green open space for local climate instrument is still identified as one of the three lowest countries in Southeast Asia in the number of green open space areas. We found that the regulating process of development rights and property rights, in the construction of Indonesian law, still requires many alternative efforts to this day in providing urban green open spaces. The delivery of desired outcomes depends on the alternative policy as a form of legal politics in compensating planning and community interests through developing green open spaces in an ecoregion approach.

This writing was shaped by the understandings of the author with regards to the development of urban green open space regulating issues in Indonesia as one of the emerging country group in Asia and Jakarta as the second-most populous urban area in the world. This paper aims to work toward providing green urban open spaces in Indonesia that has been densely built up and on it has attached land rights, through a specific spatial policy that contains zoning regulations for the provision of public green open spaces on top of residential houses built on the green zoning plans.

Replacing space is a challenge in maintaining public open space after land consolidation. Mojosongo subdistrict, Indonesia, also experienced replacing space due to social, economic and physical changes after more 20 years of consolidation. This study aims to analyze the replacing space of public open spaces after land consolidation in the Mojosongo Berseri I Housing.

This research uses a qualitative method through a case study approach. Secondary data from document reviews land consolidation. Primary data were collected through observation and in-depth interviews using snowball sampling techniques with 35 informants. The analysis techniques used are qualitative descriptive, spatial analysis and pattern matching analysis through comparing empirical case studies with relevant literature.

Public open spaces have changed function and form. The “replacing space” carried out by the community involves converting public open spaces into built-up areas used for residential purposes and commercial activities. Driving factors for “replacing space” include increase in family members, economic pressures, inflexible building concepts, lack of meaning of space, no supervision/sanctions and not optimal space.

The meaning of replacing space does not only change “space” to “place,” but can also cause changes in the form and function of a place carried out by communities. Thus, space allocation is needed according to community needs, preferences and activities to create a sense of place that is supported by regulations and supervision.

This paper aims to assess the marginal value of several types of open space in a single family residential market. It also aims to test the hypothesis that locating closer to open spaces might be a substitute for the size of a homeowner's own yard.

Using data from Wake County, North Carolina in the US hedonic modeling is used to estimate the house price as a function of the quantities of a property's characteristics, including the property's access to different types of open spaces, property structural features, public services, disamenity features, neighborhood socio‐economic characteristics, and accessibility measures.

The findings were that housing prices increase with a property's proximity to certain types of open land uses, and that the size of those nearby open spaces also impacts home price. More importantly, the findings concluded that the value of being adjacent to public open spaces, having more public open spaces within walking distance of the property, and being closer to the nearest open space is greater for properties with smaller private yards.

This paper explicitly tests the relationship between yard size and the proximity value of various types of open spaces. The paper also discusses the implications of the research findings for land use planning and smart growth development.

This study examines the relationship between quality and quantity of open space in residential areas and the sense of community of Chinese older adults in Hong Kong.

A survey was conducted with 257 adults aged 55 and over in Kwun Tong, Hong Kong. The quality of open space was assessed from four dimensions: social and recreational facilities, entrance, location and environment. Geographic information system (GIS) was used to evaluate the quantity of open space in terms of size and amount.

The result shows that the environment has a strong influence on the sense of community, while the quantity of open space does not. The results provide urban planners with evidence for open space planning in the future. Urban planners should consider building more people-oriented environment; such as green areas instead of merely increasing the size, amount and facilities of open space. The Hong Kong Government also needs to review the current standardised planning guideline in order to maximise the social connection of older adults.

This cross-sectional study tried to understand the relationship between the quality and quantity of open spaces and sense of community in Chinese older adults in Hong Kong. It is one of the few studies to simultaneously examine both the quality and quantity of open spaces when studying its relationship with sense of community.
