“…The G2SFCA model, which was first proposed by Dai [30] and later used by many researchers to evaluate park accessibility [33][34][35]44,45], is an extension of the traditional model [31] that modifies the distance-decay function based on a threshold travel time. The method is implemented using a two-step procedure.…”

“…Nine amenities, such as baseball fields and picnic areas, were added as desirable physical activity attractions, and these amenities were recorded in binary terms (1 if the amenity was available at a park and 0 otherwise). However, this list is not exhaustive, nor does it reflect the quantity or quality of each amenity [34]. In this study, we present a new index, "effective activity area", to calculate the capacity of supply more accurately.…”

“…Second, although we considered the heterogeneity of the built environment in residential communities, the characteristics and preferences of the users were ignored. For example, people with disabilities need considerable park services, and teenagers may favor active sports such as soccer and tennis, whereas older people prefer walking on park trails and more passive entertainment [34]. Therefore, further research should focus on the corresponding relationship between the demand side and the supply side to develop more realistic models for public facilities.…”

“…Several studies have shown that living in proximity to parks contributes to lower rates of overweight and obesity [5], cardiovascular disease [6], and even mental health problems [7]. A clear positive relationship exists among urban parks, their use, and well-being [8], limitations are that (1) supply indicators mainly consider park size [33] and ignore other available indexes that play essential roles in promoting regular physical activity [29]; (2) each catchment area is set at a fixed distance, regardless of park type and attractiveness [34]; and (3) areal unit problem effects, which assume that all people within the geographic boundary (i.e., district or subdistrict) enjoy uniform access, can hardly be avoided owing to a lack of community-level or individual-level data. Subsequently, Dony et al developed a variable-width floating catchment area (VFCA) method to address the fixed catchment problem, by incorporating catchment areas of varying sizes [34].…”

A major concern of social equity and environmental justice is whether urban green resources are equitably distributed across the compact megacities of China. Many previous studies have evaluated the disparities in park access among various social groups, but few researchers have considered the heterogeneity of the built environment in residential communities. This study revisits an increasingly popular Gaussian-two-step floating catchment area (G2SFCA) model and mainly improves its two core parameters, the comprehensive supply indicator and variable catchment, in order to realistically evaluate park accessibility under different travel modes. We choose Nanjing city, China, as the study case in which to evaluate differences in public park access with respect to gated and open communities using our improved model. Moreover, gated communities have been further divided into three categories, which represent differences in a community's ability to provide daily physical activities, to more deeply explore disparities in public park services. The results show that (1) the spatial accessibility of parks in Nanjing city is not evenly distributed, with communities located north of the Yangtze River having inferior park accessibility; (2) residents who live in open communities are more restricted with regard to access to parks than those in gated communities, although they experience relatively small differences under the walking mode; (3) gated communities with no internal park ("club park") enjoy better public park services; and (4) residents living in 105 open communities and 167 gated communities without a club park can be regarded as the most vulnerable groups based on the lack of park services. The results of this study can provide a scientific basis for policy makers to target specific communities of vulnerable groups for further urban park development. and urban parks play a significant role in promoting people's well-being. However, these benefits can be enjoyed only when urban parks are easily and reasonably accessible to urban dwellers and have sufficient effective activity area and amenities. In addition, urban parks are often unevenly distributed across cities, which raises issues such as environmental justice. Therefore, accurately assessing park accessibility is important to identify spatial disparities and locations that require intervention.Access to parks is influenced by many objective factors (also called spatial factors) that can be interpreted on the basis of three main aspects: supply, demand, and the connection between them. Supply may include, but is not limited to park acreage and park quality [9]. Demand refers to population size and structure, such as the presence of children, senior citizens, and racial and religious groups [10]. Regarding the connection among these spatial factors in terms of issues such as geographic barriers, substantial evidence suggests that proximity, the physical road environment, and transport modes [11,12] from residential districts to parks are closely associated with ...

Urban green spaces management during the COVID‐19 pandemic: Experiences from Kraków, Poland

et al. 2022

SARS-CoV-2 (COVID-19) has spread all over the world, significantly affecting our everyday lives. People changed their habits during the pandemic and made use of urban green spaces (UGS). Our Web of Science and Scopus queries confirm a knowledge gap in green space planning and public space management studies in the field of UGS availability during COVID-19. Therefore, the purpose of our research was to determine the impact of the COVID-19 pandemic on urban green spaces management, identify the needs of the residents in terms of urban green spaces furniture, and assess the accessibility of urban green spaces to propose recommendations for the institution charged with managing urban green spaces in the City (Krakow). To this end, we used an expert interview, spatial analyses, and survey research among residents of Krak ow, one of the largest cities in Poland. The survey involved 1350 respondents. The spatial analyses employed geoprocessing algorithms and GIS tools.The results showed that 96% of Krak ow citizens have access to urban green spaces within 300 m from their homes. Therefore, UGS are an important part of the City's identity, making their reasonable management vital, especially during crises. The respondents indicated that the existing UGS needed more lighting, rubbish bins, and benches as places of respite. Results of the expert interview showed that the COVID-19 pandemic has affected urban green spaces management. The results may influence urban green spaces management, and the research is an innovative combination of spatial analysis, a qualitative approach (expert interview), and a quantitative method (a survey) proposing new procedures for analysing UGS.
