“…Urban, or peri-urban, agriculture is a type of farming within urban boundaries at the local-to-regional level to grow food on a small scale [39,40]. Along with agriculture, it involves the development of green infrastructure in a city or city boundary landscape, see [41,42].…”

As a response to food security, urban agriculture is essential for sustainable development. The primary goal of this study is to provide the basic formulation and theoretical knowledge for sustainable urban agriculture by analyzing the impact of urbanization on urban agriculture and food security. For the food security assessment, the variables included food consumption and quality of food as the independent variables, and monthly income of local dwellers as the dependent variable; these were considered for the regression analysis and statistical analysis. The food security assessment was checked and expressed using regression values of R, which was 0.857, and an adjusted R square, with a value of 0.728. The results show extensive change in food security issues and land use due to urbanization causes, large-scale damage to agricultural land in the area, and loss of biodiversity, which threaten food security by converting natural land into built-up areas. The study concludes that urban agriculture is a fundamental environmental activity to ensure food security by increasing food production for locals and improving urban biodiversity.

“…Consequently, our study incorporated other aspects of vulnerability, such as crime rates and housing barriers, which can indirectly influence income status. Furthermore, certain studies have taken population density, floor area, and household size into account as socio-economic variables, potentially influencing the assessment of the green space relationship [61][62][63]. To address this aspect, we also included population density, built-up area, and household size as control variables in our model.…”

Green spaces have been recognised for their positive impact on residents’ health and well-being. However, equitable access to these spaces remains a concern as certain social groups face barriers to reaching public green areas (PGS). Existing studies have explored the relationship between green spaces and vulnerable populations but have often overlooked the spatial variations in accessibility experienced by these groups. This research aimed to investigate the spatial association between green space accessibility and five key variables representing vulnerability: age, educational deprivation, health deprivation, crime rates, and housing barriers. Ordinary least squares and multi-scale geographically weighted regression (MGWR) techniques were employed to analyse the relationship between the nearest distance to public green spaces and the challenges experienced by vulnerable groups based on socioeconomic factors in England. The findings highlight disparities in open green space access for vulnerable groups, particularly older adults and individuals with limited education and housing accessibility, who are more likely to face restricted access to green spaces. There was a negative correlation found between health deprivation and the accessibility of green spaces, indicating people who suffer from the disease may live closer to green spaces. Surprisingly, although a positive association was observed between crime risk and distance to public green space in most areas, there were specific areas that exhibit a negative correlation between them. This study emphasises the importance of considering the perspectives of vulnerable groups in addressing PGS inequality and underscores the need for inclusive public green space planning and policy development.

“…However, in the early period of rapid urbanization and rapid economic and population growth, urban ecosystems were irreversibly affected [2]. At the same time, the enormous contradiction in the relationship between resource supply and demand limits the equity of green space resources for residents [3]. In the past, UGSs were mostly used as appendages of urban construction.…”

Urban green space (UGS) is an important public infrastructure. However, the rapid development of cities and the insufficient supply and uneven distribution of UGSs have led to a mismatch between them and various needs, which has seriously affected environmental justice and social equity. This study discusses the fairness of UGS from the perspective of supply and demand and improves the theoretical framework of supply and demand combination evaluation. First, this study analyzes the supply of UGSs through accessibility analysis and evaluates their demand from both subjective and objective dimensions. Second, the fairness of UGS is analyzed from a Gini coefficient and spatial evaluation perspective. Finally, the location optimization of UGSs is performed, which provides strategic guidance for the improvement of UGSs in Chengdu. The research results based on Chengdu City show that the travel mode directly affects the supply range of UGSs and is reflected in their fairness. At the same time, in the case of a highly dense population, UGSs in the city are in short supply; that is, the equity is negatively correlated with the population. This study provides a new perspective to evaluate UGS fairness and can be a reference for UGS optimization decisions.
