Urbanization is a global phenomenon which is projected by the United Nations to grow annually at 65 million between 2000 and 2030 in developing countries. As an archipelagic nation, the Philippines is considered as a highly urbanized nation where over three-fourths of its population is estimated to reside in urban areas, posting a proportion of one person residing in rural area for every three in urban area. The National Capital Region (NCR), the core region of the counry, registers a 100% urbanization level and where the most densely populated areas converged. It generally exhibits an urban population growth rate that exceeds the national growth rate. Manila, the capital city of the Philippines, is the second largest and the world’s most densely populated city given its small land area and huge human population. The concentration of people in this city and the urbanization processes are foreseen to create environmental stress leading to potential biodiversity losses coupled with other urban environmental occurrences such as flooding, air pollution, sea level rise, earthquake, subsidence, traffic congestion, water pollution, among others. These natural and man-made hazards pose challenge to the multi-functional uses and various benefits of urban green spaces (UGS). UGS play a significant role in enhancing the quality and resiliency of the environment as well as in improving the health and general well being of city dwellers. It is in this context that the challenges and opportunities of UGS are examined. The paper attempts to identify and determine the factors that influence UGS as basis for urban biodiversity planning and management.

Urban green spaces are intended to provide citizens with calm environments free of annoying city noises. This requires a thorough understanding of noise emission and related exposure to sounds in green spaces. This research investigates noise perception in various spots in an urban green space. For this purpose, the study has been conducted in the grand garden of the city of Dresden. The garden covers 1.8 square kilometers of various landscapes, including water streams, park railways, fountains, bridges, roads for bicycles and pedestrians etc. Noise perception was investigated at eleven spots with emphasis on four noise types: nature noise, human noise, traffic noise, and technical noise. In parallel, audio-visual recordings were conducted for each spot to identify the connection between the perceptual measures and the psychoacoustic parameters. These spots are categorized based on the resulting perception and psychoacoustic parameters. In addition, the visual effect of each spot on final perception is investigated. Eventually, annoyance for each spot is identified based on the corresponding participants' perception and is associated with the relevant psychoacoustic parameters.

This study investigates the associations between characteristics of urban green spaces and frequency and duration of self-reported physical activity in the city of Aydın, Turkey. Data were collected through a survey with 420 participants. We analysed the associations between characteristics of urban green spaces and frequency and duration of general population’ physical activity and physical activity of physically active people with multivariate linear regression while controlling for sex, age, marital status, education level, occupation and household income level. Results showed that for the general population, short distance to urban green spaces, many trees, exercise equipment and picnic areas were positively associated with frequency of physical activity, while barbecue and fire places negatively associated with duration of physical activity. For physically active people, many trees, soccer and basketball fields were positively associated with their frequency of physical activity, but water features were negatively correlated with frequency of physical activity. In regard to duration of physical activity for physically active people, findings showed lawn and exercise equipment were positively correlated with duration of physical activity, while water features, barbecue and fire places were negatively correlated with duration of physical activity. The findings indicate that levels of physical activity in urban green spaces could be promoted with many trees, exercise equipment, picnic areas and lawn. However, causal relationship needs to be conducted with intervention or longitudinal studies.

In a country like Pakistan, the presence of urban greening and parks are very essential for the well-being ofits citizens. The resident’s awareness about urban green spaces (UGSs) is essential as it would not only help towards ahealthier environment, but prepare residents to manage these spaces efficiently through local resources. This formulatesthe rationale behind current research work. This research is aimed at studying about the resident’s perception for UGS’sattributes like environmental, negative and positive. Another major focus of this research is to analyze thesocioeconomic differentials and its consequent impacts on resident’s perception about urban green spaces, which hasbeen probed with the help of MANOVA (Multivariate Analysis of Variance). In this regard the primary data of 223visitors were collected by random sampling method from eight major parks of Lahore, Pakistan. The findings of thissurvey of resident’s perception have shown that mostly male, single, low and middle class, and educated people visitthe urban green spaces and they are highly indebted by their environmental and health benefits. For the selectedcharacteristics of urban green areas, the resident’s perception has revealed that there exists an insignificant relationshipwith age and marital status of the respondents while the most significant relation was shown by the residents whovisited the UGSs regularly as ‘ρ’ value is less than the set significance level of 0.05. This study has highlighted a direneed of such UGSs in the city of Lahore which is known to be the “City of Gardens”. This could raise the spirits ofadministrators, city managers and planners to take immediate action in this regard.

The identification of service areas of urban green spaces and areas with lack of these is increasingly necessary within city planning and management, as it translates into important indicators for the assessment of quality of life. In this setting, it is important to evaluate the attractiveness and accessibility dynamics through a set of attributes, taking into account the local reality of the territory under study. This work presents an operational methodology associated with these dynamics in local urban green spaces, assisting in the planning and management of this type of facilities. The methodology is supported firstly on questionnaire surveys and then on network analysis, processing spatial data in a Geographic Information Systems (GIS) environment. In the case study, two local green spaces in Lisbon were selected, on a local perspective explorative approach. Through field data, it was possible to identify service areas for both spaces, and compare the results with references in the literature. It was also possible to recognise areas with lack of these spaces. The difficulty to evaluate the dynamics of real individuals in their choices of urban green spaces and the respective route is a major challenge to the application of the methodology. In this sense it becomes imperative to develop different instruments and adapt them to other types of urban green spaces.

In the current context of global urbanization, interdisciplinary research is needed to identify planning and management practices in urban green spaces (UGS) that would enhance both biodiversity and visitors’ well-being. The perception of landscape heterogeneity, a core ecological concept, has been demonstrated to have a positive impact on visitors’ psychological restoration. In order to apply these findings within UGS to planning and management practices, we need to characterize visitors’ perception of landscape heterogeneity. We gathered data on 390 visitors’ perception of landscape heterogeneity. Our results highlighted that visitors perceive landscape heterogeneity through the mixing of different heights of three vegetation strata and flower areas. Planning and management practices should enhance this landscape aspect within UGS to simultaneously promote biodiversity and visitors’ psychological well-being.

In accordance with SDG N11.7, each city should work on providing “by 2030, universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities”. This target became even more crucial during the COVID-19 pandemic restrictions. This paper presents and discuss a method for (i) assessing the current distribution and accessibility of urban green spaces (UGSs) in a city using hierarchical network distances; and (ii) quantifying the per capita values of accessible UGSs, also in light of the restrictions in place, namely social distancing during the COVID-19 pandemic. The methods have been tested in the city of Bologna, and the results highlight urban areas that suffer from a scarcity of accessible UGSs and identify potentially overcrowded UGSs, assessing residents’ pressure over diverse UGSs of the city in question. Based on our results, this work allows for the identification of priorities of intervention to overcome these issues, while also considering temporary solutions for facing the eventual scarce provision of UGSs and related health and wellbeing benefits in periods of movement restrictions.
