How did the COVID-19 pandemic impact urban green spaces? A multi-scale assessment of Jeddah megacity (Saudi Arabia)

The outbreak of the COVID-19 pandemic emerged as a global public health threat. In this crisis period, urban parks provided multiple ecosystem services and direct/indirect benefits to mental and physical health. However, the use patterns, attitudes, and perceptions of urban park visitors remained unexplored in Saudi cities. This study aimed to find out the use patterns, attitudes, and perceptions of people regarding urban parks during the COVID-19 pandemic, and the findings were compared with non-pandemic periods. Two urban parks (Al Masarah Garden and Al Jamaa Garden) in Jeddah megacity (Saudi Arabia) were assessed, and 215 respondents were surveyed to fulfil the objectives of the study. The study applied a questionnaire survey and field observations to understand the impact of the COVID-19 pandemic on the use patterns, attitudes, and perceptions of urban park visitors. Non-parametric tests (Kruskal–Wallis and Mann–Whitney tests) were performed to find out the impact of sociodemographic factors (such as age, gender, and education). From the results, it was found that the COVID-19 pandemic had a substantial impact on the use, attitudes, and perceptions of urban parks in comparison with non-pandemic periods. The number of park visitors decreased during the COVID-19 pandemic, but urban parks were crucial to people’s mental and physical well-being. The findings of this study may help to understand the importance of urban parks as green spaces and to implement measures to enhance the quality and quantity of urban green spaces in Saudi cities.     

Between Big Ideas and Daily Realities – The roles and perspectives of Danish municipal green space managers on public involvement in green space maintenance

Public involvement (PI) in green space maintenance activities has increased during the past decades. The various (potential) benefits of PI have been recognised. Denmark, however, has no established tradition for such activities, despite its well-established tradition of volunteering. Local authorities have traditionally been the sovereign entity within public green space management, reflecting a hierarchical mode of governance. Yet, an increased call for new forms of local democracy and for new governance modes has resulted in growing attention for PI practices. Hence more knowledge is needed, for example on ongoing changes in governance arrangements regarding municipal green space.This paper thus aims to gain insight into (a) current governance arrangements with respect to municipal green space maintenance as well as temporal changes in these and (b) the consequences of the former for governmental actors and municipal managers in particular. An analytical framework based on governance theory and the Policy Arrangement Approach was developed to meet these aims. Data was collected by means of selected semi-structured interviews with green space managers from ten Danish municipalities.Findings show that green space PI occurred in all ten municipalities and thus that governance arrangements had started to include non-government actors, signalling a possible shift to co-governance from more common hierarchical governance modes. Green space managers felt themselves often ill-prepared for new governance arrangements and PI, e.g. in terms of lack of training and expertise. They based themselves strongly on their own experiences and preferences. More responsibility had been allocated to citizens, but often only to a select group of those who were already organised and/or had good connections with local authorities (i.e. closed co-governance). Green space managers listed a number of benefits of PI, generally adhering to the prevailing discourse of more co-governance. However, they also noted a number of challenges, including discrepancies between current maintenance practices and more PI. These, as well as a wider understanding of changing governance arrangements in green space management and maintenance, need to be addressed in future research.     

上海市公园绿地群落的“近自然性”初探

文章通过对上海市区内比较有代表性的三座公园绿地:延中绿地、世纪公园和上海植物园的植物群落组成的区系成份的分析对城市绿地公园人工植物群落的"近自然性"进行了尝试性的研究,并运用经典的相似性系数法对结果进行了评估。结果显示,世纪公园的群落组成最接近自然群落,上海植物园次之,延中绿地最差。总体来讲,上海城市公园绿地对于乡土植物的保护和利用尚有待提高。

Exploration of Ecotypic High-Tech Building

The high-tech architecture came into being in 1960s'. Now it becomes one of the very important architectural styles. In the turn of 20th century, it's broken into several branches, ecotypic high tech architecture is the main stream of those, and has enormous influence. This paper analyzes the expression and motivation of ecotypic high-tech architecture, evaluates the new imagination and especially emphasizes its characteristics and methods of technology application.
