Abstract Superblocks are an urban transformation strategy to create pedestrian-centric neighbourhoods. This study presents a methodological framework to assess the potential for urban green space (UGS) arising from superblock design. A quantitative assessment of the current state of UGS in superblocks is performed with geospatial analysis and earth observation techniques for a Swiss city. We find that UGS varies considerably across identified locations and decreases with smaller block sizes. Based on two scenarios, we illustrate how information on current UGS at the street or block level can be used to benchmark and assess urban greening potentials at superblock sites.

Vegetative Indices

The state of ecological balance of cities is determined by the analysis of the qualitative composition of green space. The lack of green space inventory in small towns in the Kyiv region has prompted the use of express analysis provided by the EOS Land Viewer platform, which allows obtaining an instantaneous distribution of the urban and suburban territories by a number of vegetative indices and in recent years – by scene classification. The purpose of the study is to determine the current state and dynamics of the ratio of vegetation and built-up cover of the territories of small towns in Kyiv region with establishing the rating of towns by eco-balance of territories. The distribution of the territory of small towns by the most common vegetation index NDVI, as well as by SAVI, which is more suitable for areas with vegetation coverage of less than 30%, has been monitored. We found that the share of dense vegetation in the territory of towns increased on average from 2.4 to 49.3% during 1990–2018. The share of the vegetation cover of moderate density decreased from 40.8 to 27.1%, and of sparse one from 37.5 to 14.9%. High variability of these indicators is noted. The share of open area for small towns decreased on average from 15.4 to 3.8%. The vegetation-free areas in 1990, 2005 and 2018 accounted for 3.8, 2.6 and 4.4%, respectively, which may indicate the intensive expansion of built-up areas over the last fifteen years. The development of urban greening systems was completely individual and depended not only on natural conditions but also on the manifestations of anthropogenic activity. The reduction of the ecological balance of the territories of small towns as of 2018 took place in the following sequence – Irpin, Tarashcha, Boiarka, Rzhyshchiv, Kaharlyk, Skvyra, Myronivka, Yahotyn, Uzyn.

With the widespread application of Geographic Information System (GIS) technology in urban green space management system, the refinement of greening management puts forward the demand for upgrading the system. Taking the construction of urban green space management system in Wuxi as an example, this paper reverses the conventional operation of building database before system, and puts forward the method of management-oriented system upgrading. Through the research on the status quo of urban greening management, starting from the analysis of management requirements, the management requirements are transformed into system design requirements, so that the system upgrade is guided by the urban greening management requirements. It solves the problems of large amount of and time-consuming data input during the upgrading and construction of the system, which leads to long process and data lag when it is put into use. After the rapid upgrade, along with the refinement of daily management, the system has been continuously improved, and has received good results in the depth and breadth of data.

Health And Well Being

It is generally agreed that green space has a positive effect on the health and well-being of urban residents. A number of papers have studied the relationship between green space and various sociodemographic characteristics; however, little is known about how perceptions of green space affect health and well-being differently between men and women. Such knowledge is significant for informing policy makers in designing urban green space to benefit the health and well-being of all people. In addition, urban greening has rarely been studied in the context of the UN 2030 Agenda and the UN New Urban Agenda. This study examines gender disparities in perceived green space and health and well-being, the effect of perceived green space, personal, and family variables on subjective health and well-being, and the interactive effects of perceived green space, personal, and family variables on health and well-being. The analyses were based on a survey of 9325 participants in 40 Chinese cities, using the Geographical Detector method. The results suggest that men tend to have a higher perception of green space but lower subjective health and well-being than women. Compared to health, well-being is more affected by perception of urban green space and personal and family factors. Perception of urban green space has a higher effect on men’s health and well-being than women’s. Women’s health and well-being tends to be more affected by personal and family factors than men’s. There are clear interactive effects of perceived green space, personal, and family variables on health and well-being. The combined effect is greater than the sum of individual effects on health and well-being, suggesting complexity in sustainable urban green space development with attention to gender equality in the context of the UN Agendas for sustainable development.

World urban areas are increasingly dabbling with the triple challenge of pollution, congestion and environmental degradation. The quest for sanity and healthy urban living led to the introduction of urban green space initiatives. Green space has become primordial in urban areas as it enhances public health, recreation, amenities and property values through its location, accessibility, proximity and serviceability. In a bid to develop an urban green space in Bamenda, the City Council identified the Bamenda escarpment in 2011 for protection. This was followed by a Green City Initiative now captioned the Green City Project. The Bamenda City Council partnering with the UN-Habitat and the Dordrecht/Gorinchem City Councils of the Netherlands seeks to implement an urban greening project with major focus to map out potential areas for creating parks in Bamenda. This project which is a novelty in the rapidly changing urban landscape of Cameroon seeks to contribute to building a green economy that enhances nature, environmental protection and at the same time offers economic and social benefits to its citizens. In this study, we examine the opportunities and challenges of urban greening in Bamenda. Some 50 inhabitants around the escarpment were purposively sampled while council authorities and other stakeholders were interviewed in the Bamenda I municipality in order to assess the opportunities, challenges and prospects for the project. This was complemented by secondary data obtained from the Bamenda City Council. The conclusion drawn is that the initiative will provide opportunities for employment, generate revenue for the City Council and prevent uncontrolled city sprawl against the backdrop of the relatively unstable nature of the foothills (due to mass wasting processes) and land use competition, largely driven by population growth and the daunting task of relocating prior users. We therefore argue in favour of the effective application of urban development policies to restrict encroachment around the area and to engage in slope stabilization where necessary.

We take Shunde District, Foshan City in Guangdong Province for example, to carry out SWOT analysis of urban greening maintenance and management. The strengths of greening management and maintenance in Shunde District are as follows: (i) The greening area and quality are continuously improved in the downtown of Shunde District; (ii) The management and maintenance work is carried out well; (iii) The management and maintenance level tends to be increasingly perfected. The weaknesses of greening management and maintenance are as follows: (i) The fees for greening management and maintenance are very low; (ii) There is corner as yet untouched in the junction of some town streets; (iii) The greening management and maintenance technicians are unprofessional; (iv) The greening management is not in place; (v) There is management vacancy phenomenon in the management and maintenance of regional green space; (vi) The design and construction phase is flawed. Finally, based on the analysis of strengths and weaknesses of greening, we put forth the recommendations for the development of management and maintenance in urban green space.
