This study aims to investigate the factors influencing NAI concentration in urban and suburban forest parks, enhancing our understanding of the correlation between NAIs and environmental factors. Songjiacheng Urban Forest Park and Runyang Wetland Suburban Forest Park in Yangzhou City were selected as the subjects of this research, and continuous measurements of NAI concentration were conducted over a three-year period. Additionally, seven meteorological factors were monitored. A random forest model was employed to analyze and compare the data from the two forest parks, identifying the environmental factors with significant impacts on NAI concentration. The results indicate that in Songjiacheng Urban Forest Park, NAIs exhibited significant sensitivity to temperature, followed by atmospheric pressure. Conversely, in Runyang Wetland Suburban Forest Park, PM2.5 (particulate matter 2.5) exerted the greatest impact on NAIs, followed by humidity. We conducted a thorough analysis of data to explore the intricate connections between negative air ions and a variety of environmental factors within two urban forest parks. Our findings have significantly broadened our perspective on the characteristics of Negative Air Ions (NAIs) and their management implications within these urban green spaces. This enhanced understanding is pivotal for developing more effective strategies for environmental stewardship and the preservation of these vital urban ecosystems.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"24 ","pages":"Article 100181"},"PeriodicalIF":3.9,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this research tests a novel set of indexes with an underused method of ethnographic video interviews with 14 citizens of a known sustainable neighbourhood in Stockholm, Sweden. A thematic analysis conducted on 28 h of interview data collected over a 4-week period yielded 5 main themes, from outdoor public spaces. Self-sufficiency findings suggest that citizens 1) perceive small scale self-sufficiency to be challenged by large scale structural efficiency and 2) circular actions with food waste to biogas can develop the self-sufficiency index further. Community plot ratio findings suggest that citizens 3) perceive community spaces to be accessible for all but not used by all. Civic generosity findings suggest citizens 4) perceive an imbalance between self-interests of the individual versus collective interests of the community, while 5) experienced citizens feel personally responsible to pioneer civic generosity interactions. UNEP indexes for designing neighbourhoods can define local sustainability, however, our findings support this, only if they can be acted upon by the citizens who live there.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"24 ","pages":"Article 100180"},"PeriodicalIF":3.9,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The situation is exacerbated by the rapid urban development in coastal cities in the GCC countries over the past 20 years. This review study examined the climate change hazards that are having negative impacts on the resilience of coastal cities in the GCC countries using a systematic literature review approach. It also explores the urban resilience strategies implemented towards climate change hazards mitigation and adaptation in order to build climate-resilient coastal cities in the GCC countries. A total of 48 peer-reviewed articles were included in the systematic review derived from Scopus, WoS, and Google Scholar, covering the nine coastal cities in the six GCC countries. Most of the studies were focused on the coastal cities of Jeddah (30 %) in Saudi Arabia and Doha (24 %) in Qatar, compared to the other seven coastal cities in the GCC countries. Flooding, rising temperature, sea level rise, dust storms, cyclones, and migration of sand dunes were the six most reported climate change hazards, respectively, posing significant negative impacts on coastal cities and undermining their resilience to current and future climate change impacts. The various urban resilience strategies implemented against climate change hazards were categorised under five resilience dimensions: infrastructure resilience, social resilience, environmental resilience, economic resilience, and governance and policy resilience dimensions. The infrastructure resilience dimension was reported in 50.7 % of the studies, since it is the most implemented, while far less research attention was given to the environmental (14.5 %), government and policy (8.7 %), and economic (2.9 %) resilience dimensions of coastal cities in the GCC countries. The urban resilience strategies for climate mitigation and adaptation were reported to have successfully reduced the vulnerability of coastal cities to climate change hazards over the past decade, by improving their climate resilience. The findings contribute to informing urban planning policy-making focused on coastal environmental management in the coastal cities of the GCC countries that should further enhance the climate resilience of these coastal cities.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"24 ","pages":"Article 100177"},"PeriodicalIF":3.9,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the degree of PE to PM_2.5 in five growing cities of Rwanda based on individual’s time-activity patterns and visited microenvironments. A total of 150 participants were recruited to collect real-time personal and ambient PM_2.5 measurements during their routine activities in different outdoor and indoor microenvironments for five consecutive days in dry season. Each participant was an employee in one of the six most prevalent urban economic activities found in their city of residence: workshops, flour mill plants, near road activities, garages, markets, kitchens and motorcycle taxi services. The participant’s day was categorized into three most distinct microenvironments grouped under home, work, and other microenvironments (other MEs). PE to PM_2.5 assessed for all participants showed significant variability among types of activities and categories of microenvironments (p &lt; 0.05).

The electricity generation potential under alternative scenarios namely scenario 2 (landfill gas to electricity (LFGTE)), scenario 3 (mass-burn incineration), scenario 4 (hybrid LFGTE, mechanical–biological treated (MBT) anaerobic digestion (AD) and incineration), and scenario 5 (hybrid AD and refuse-derived fuel (RDF) incineration) is based on projected waste generation over the next 20 years, taking population growth into account. These four options are compared to Business as Usual (BAU). Scenario 3 has the highest electricity generation capacity at 207799.73 MWh/year, followed by hybrid RDF-incineration/MBT-AD (scenario 5), LFGTE, however, lowest generation at 30683.07 MWh/year.

The outstanding plant biomass produced by <em>Ficus</em> species explained the high soil carbon sequestration, particularly in humic organic matter, favouring soil aggregation, porosity and water retention.
