This study examined public perceptions, awareness, and willingness to pay (WTP) for urban heat island mitigation through increased tree coverage in Accra and Kumasi. The study utilized a cross-sectional mixed-methods approach and incorporated the Contingent Valuation Method (CVM) to assess respondents WTP to mitigate the UHI. A structured questionnaire was administered to a total of 240 participants to gather their responses. Findings revealed that majority of the respondents acknowledged rising urban temperatures and viewed urban trees as important in temperature regulation. Approximately 88.75 % of respondents expressed willingness to pay for improved tree coverage, with a mean WTP of GHȼ26.78 (=$2.04, May 2025 exchange rate). Factors such as age, household size, and occupation negatively and significantly influenced WTP, while income had a positive effect. However, some respondents stated unemployment, mistrust in fund use, and poor tree maintenance as key barriers to contributing financially. These findings highlight the potential for citizen-supported financing mechanisms to enhance urban greening initiatives. Integrating such willingness into urban policy can strengthen climate resilience, support nature-based solutions, and advance global sustainability commitments, especially SDG 11 (Sustainable Cities and Communities), SDG 13 (Climate Action), and SDG 15 (Life on Land).</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"28 ","pages":"Article 100242"},"PeriodicalIF":3.8,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the collection of the research activities, the main considerations for a better design of this type of solar shading systems were summarized. Furthermore, in support of critical analysis of literature, quantitative indicators relating to the impact of textile solar shading systems on the reduction of the summer heat load on buildings, on the reduction of pedestrian thermal stress and on the reduction of pedestrian exposure to UV radiation were proposed and calculated in the three Mediterranean locations (Rome, Athens, Tripoli). From the simplified evaluations proposed, considering a perfectly horizontal and continuous sun sail, with a transmission coefficient equal to 0.1, compared to the case of absence of solar shading systems, an average reduction in the incoming heat flow between 50 % and 60 %; an average reduction in the thermal stress index between 10 % and 40 %; and a reduction in the Standard Erythemal Dose (SED) of nearly 90 % were obtained, for the aforementioned locations.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"28 ","pages":"Article 100240"},"PeriodicalIF":3.8,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144916451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 2000, Sydney recorded single-pollutant events on 43% of monitored days and multi-pollutant events on 14% of monitored days. In Melbourne, single-pollutant events were recorded on 42% of monitored days, and multi-pollutant events on 8%. In Sydney, NO₂ exceeded WHO guidelines on 52% of monitored days, PM_2.5 on 13%, PM₁₀ on 4%, and O₃ on 6%. In Melbourne, NO₂ exceeded on 47% of monitored days, PM_2.5 on 4%, PM₁₀ on 6%, and O₃ on 2%. Evaluating long-term, city-scale air quality is challenging due to significant variations in spatial and temporal data coverage, especially in Melbourne. Many monitoring stations have limited temporal coverage and do not consistently monitor all key pollutants, meaning the true extent of air pollution is likely not fully captured. Since 2017, Melbourne has had only five active monitoring stations, compared to over 15 in Sydney.

Results indicated moderate total dissolved solids (TDS) (about 400 mg/L), low dissolved oxygen (DO) (less than 4 mg/L), and significant pollutant variability. Clustering indicated that the first one consisted of samples collected nearer to the landfill, exhibiting excessive chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total suspended solids (TSS), while the second one contained samples collected farther away from the landfill, demonstrating superior water quality. The WQI categorized three samples as <em>very bad</em> 405 (WQI &lt; 31) and seven as <em>bad</em> (WQI between 31 and 51.9), with the lowest value recorded as a WQI of 1.85 from a sewer.

The study’s scientific significance resides in its provision of a comprehensive WQI and specific pollution data, thereby augmenting the understanding of urban landfill effects on water quality in densely populated areas.

An assessment has been done to derive interrelationships between them and characteristics of the built environment. Rather than applying a generic Local Climate Zones classification, the built environment has been assessed by clustering the city of Darmstadt based on the UrbanReNet catalogue—a more contextual and nuanced urban typologies-based classification developed specifically for German cities. The findings of this study show that certain urban typologies are more prone to overheating, and can also significantly influence the thermal conditions of their surroundings. The latter is established by a novel multivariate regression that employs the H3 hierarchical geospatial indexing system. Further, mapping of the elderly in Darmstadt revealed that about half of them reside in settings that are at risk of overheating during a heatwave. This study provides a novel methodology to delineate areas at maximum risk of overheating. This can help prioritize heatproofing efforts to minimize the risk of excessive heat stress by focusing on the most vulnerable.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"28 ","pages":"Article 100231"},"PeriodicalIF":3.8,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144830631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the thermal and radiative properties of street facets like roads are critical urban canopy parameters (UCPs) that are used to understand heat storage and surface-air exchanges. However, the role of vehicles, especially parked ones, in modifying these surface properties and associated UCPs has been largely overlooked.
