With the growing disillusionment of hectic city life and poor liveability of the cities, restructuring of socio-spatial urban spaces is the need of the hour with the increasing demand for urban green space in the expanding towns of India in what has already been established for the planned cities of India like Chandigarh of Panjab and the Salt Lake City of West Bengal provinces, respectively. If the urbanites can access the desired environment through deep green cover and the chirping of birds and crawling of animals, it develops a rational mind for social integration and community development potentials (Miller et al., 2015; Van Hecke et al., 2017). Urban green space provides ecological benefits to the cities, such as regulating the urban heat island phenomena, reducing noise and air pollution, and various ecosystem services (Armson et al., 2012; Hamada and Ohta, 2010). It also extends multiple social, economic, and ecological roles, including therapeutic benefits, the desired surroundings for raising children, social integration, conservation easements, and community development potential (Miller et al., 2015; Hague and Siegel, 2002; Milton, 2002).

In particular to hot-humid climatic zones, many researchers agreed that solar shading is the most crucial requirement to be incorporated in to design [21]. Hence, the aim to minimize heat gain and cover urban surface as much as possible through solar shading should be the first priority in the urban landscape design of tropical climate. The term “urban green space” can be applied to a number of types of open land or undeveloped, including land planned as parks, garden, green belts, farmland, etc. The vegetation is a modifying factor of the local climate—improving urban microclimate and outdoor thermal comfort in urban spaces [22]. The presence of trees in the urban matrix may affect air temperature at a variety of spatial scales, from individual streets to city-scale modifications [4]. Benefits of incorporating landscape/open areas in city are: Vegetation can reduce energy consumption in buildingsShade building surfaces, reducing the radiant load on the envelopeInfluence wind pattern and thermal comfort

Different forms of urban green landscapes have positive impacts on the surrounding land and properties values. Urban areas can contain public parks, protected forests, unprotected forest areas, and trees growing around a house or in the neighborhood surrounding the house. Each type of forest cover, if present in or nearby an urban area, may provide different amenities to the homeowners and to the society. It affects the overall physical and built environment of the city and makes the cities attractive places not only to their own citizens, but also to external visitors. In this respect, the urban green space may have a role to play in economic development in terms of improving the quality of urban life, building a desirable “city image,” and enhancing the position of the city in respect to its competitiveness [8]. The restoration of derelict lands into green spaces increases the value of such areas and enhances their uses for recreational purposes in urban areas [170]. Urban green landscapes also improve workplace environments and commuting routes. The empirical results imply that increasing the street landscape planting ratio improves the quality of dwelling environment, in terms of both the magnitude and saturation level of the planting ratio [96]. Many modern cities around the world have already invested in increasing the green space ratios inside municipal districts. For example, the rate of growth of street landscape planting in Japan has increased threefold from 2.8% in 1977 to 9.7% in 2005 [96].
Importance–performance analysis and improvement of an urban park’s cultural ecosystem services based on users’ perspectives: A Beijing case study

In the current context of increasing social and economic inequities in cities, urban policy faces a great challenge regarding strengthening social integration. Many studies have shown that urban parks can help strengthen social connections and the sense of local belonging, while the lack of urban green space can exacerbate social and environmental inequities (Campbell et al. 2016). However, the existing policies rarely consider the establishment of urban green spaces that fairly serve all of society in every part of the city. Our case study shows that when urban policymakers consider the layout of urban parks, they should pay attention to socio-spatial unfairness. New urban parks should not be limited to single-function residential areas but should be extended to mixed-functional and non-residential functional areas. The beneficiaries of urban parks include not only residents but also non-residents. The analysis of Jingzhang Park, a case study located in a complex functional area, suggests that policymakers need conduct effective strategies for parks with specific site, district, and characteristic attributes. This research has shown that such parks provide special rest services that may not be found elsewhere, which need be taken into account by planners to provide site-specific case references for other similar areas.

With the unprecedented process of urbanization in China, the contradiction between the limitation of urban land resources and the sharp increase of population is increasingly prominent (Huang et al. 2017; Razali et al. 2018; Liu, Lin, and Li 2019). More and more buildings and impervious surfaces constantly occupy the urban green space, which further aggravates the urban problems of air pollution, water pollution, noise pollution, flooding, urban heat island, groundwater resources shortage and so on (Lei et al. 2018; Li et al. 2018a; Zhu et al. 2018; Qiao et al. 2019; Sun, Mejia, and Che 2019). As an important landscape component of the city, green infrastructure (GI) plays an important role in improving the natural environment, maintaining the ecological balance, regulating the water and air circulation of the city, mitigating the regional climate change, etc., which can effectively alleviate a series of urban problems in the process of rapid urban expansion (Wolch, Byrne, and Newell 2014; Wang et al. 2018a; Zhong et al. 2019).
Machine learning on high performance computing for urban greenspace change detection: satellite image data fusion approach

Recently, green spaces have gained focus in urban planning and governance. The US Environmental Protection Agency defines green space as, ‘land that is partly or completely covered with grass, trees, shrubs, or other vegetation’ (Environmental Protection Agency). As such, green spaces include private parks, community gardens, cemeteries, schoolyards, playgrounds, and public seating areas. Urban green space and its functions are under increasing pressures induced by urbanisation including land conversion into impervious surfaces, soil, air pollution, and intense disturbances. Ecological assessment of urban green space can provide valuable information for urban planning and management that can be used to protect and enhance ecosystem services in urban green spaces. Automatic measurements of green spaces come mainly from geographic information system (GIS) data and remotely sensed data (Parent et al. 2015). For example, Tian et al. (2014) used high-quality digital maps with a spatial resolution of 0.5 m × 0.5 m to analyse the landscape pattern of urban green space for ecological quality. Gupta et al. (2012) calculated a neighbourhood green index to quantify homogenous greenness from multi-temporal satellite images. Periodically obtained remotely sensed imagery is suitable for updating the spatial distribution patterns of green spaces. However, with rapidly changing landscapes, as well as multiple sources of remote sensing data (available in almost real time), the analysis of green space assessment and change detection face several challenges.
