These conditions directly impact people’s health and well-being, such as access to medical care or a healthy lifestyle. Human thermal comfort is paramount for people’s health, both physical and mental. In this paper, the study compares two microclimate mobile weather stations (MWS) based on a set of users’-based assessment criteria (usability, user-friendliness, sensors) and thermal comfort (UTCI) results accuracy. The comparison was carried out through continuous mobile transect measurements lasting an hour and a half, conducted on two summer days in Lisbon across distinct urban morphological settings. This research was developed to assist future researchers in urban climatology with the design of microscale studies, particularly in relation to equipment selection, performance assessment, and methodological procedures. In terms of performance, we found the RMSE to be 1.3 °C for air temperature, 1.6 % for relative humidity, 1.3 m/s for wind speed, and 8.4 W/m2 for solar radiation for MWS 1, and 1.5 °C for air temperature, 2.9 % for relative humidity, 1.5 m/s for wind speed, and 11.6 W/m2 for radiation for MWS 2. Both MWS units exhibited a consistent performance, however, MWS 1 demonstrated greater overall accuracy, particularly in the measurement of air temperature, relative humidity, and wind speed. Differences were also observed between the sensors of MWS 1 and MWS 2, as well as in the MWS usability, factors which may be significant depending on the users’ objectives and available resources. Despite this, both MWS units were deemed suitable for deployment in urban environments, with MWS 2 offering a more intuitive user experience. The findings of this study are particularly relevant for those beginning mobile meteorological measurements, as well as for researchers aiming to address urban heat stress and enhance public well-being and thermal comfort through their work. However, the study is limited by its short duration and geographic scope, and further research is needed to expand its applicability to diverse urban settings.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"27 ","pages":"Article 100212"},"PeriodicalIF":3.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144167258","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}

However, it remains unclear how urban farmers adapt to these impacts and what strategies they employ to mitigate climate-related challenges. This study selected 85 urban farmers across three selected locations in Kumasi, Ghana to investigate the adaptation practices and challenges, aiming to inform agricultural and urban planning efforts. Factor analysis, Ordinal regression and Relative Importance Index (RII) were used to analyse the quantitative data, while content analysis was used for qualitative data. The study identified three key adaptation strategies. First, farmers prefer planting local crop varieties over foreign seeds due to their reliable germination; second, some farmers expand their farms to boost production; and third, others relocate to different sites to allow exhausted land to regain fertility. However, these adaptation strategies are hindered by several challenges such as institutional and technological limitations, financial constraints and lack of access to climate information, and delays in extension support and adaptation efforts. The study also found that socioeconomic factors such as farm income, land ownership, and membership in farmer associations also influence the adoption of certain practices. These findings highlight the urgent need for the agricultural and physical planning departments to regularly monitor urban farming activities and give urban farmers the necessary attention. This will help identify urban farmers’ needs − tools, equipment, extension services, and modern technology thus enhancing climate resilience and sustainable urban agriculture.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"27 ","pages":"Article 100208"},"PeriodicalIF":3.9,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125320","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}

Addressing the interconnected challenges to urban resilience – including climate regulation, food security, and urban health – requires a holistic and integrated approach. Urban green spaces hold huge potential in this effort, but maximizing their contributions depends on enhancing soil security, which encompasses both soil health and, importantly, promoting essential urban human-soil interactions. In this context, urban soil stewardship such as community composting plays a crucial but often overlooked role in fostering a more integrated and regenerative approach to achieving greater urban resilience. Using Q methodology and qualitative methods, this study investigates perceptions of individuals participating in community composting in the densely-populated city-state of Singapore. The Q study identified three distinct motivational ‘personas’ prioritising: (a) the ability to act, (b) personal satisfaction and growth, and (c) a personal sense-of-duty to the environment and future generations. Participants also shared reasons for their initial and continued participation and identified key required participation ‘enablers’. Based on the findings, recommendations are proposed to inform multistakeholder policies, strategies and governance arrangements able to unlock soil stewardship’s potential as a strategy to enhance resilience in the country. Whilst focused on the Singaporean context, findings are nonetheless relevant to diverse stakeholders attempting to promote multistakeholder policy and practice required to build urban resilience and address commitments to the Sustainable Development Goals and Paris Agreement.</div></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"27 ","pages":"Article 100205"},"PeriodicalIF":3.9,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937072","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}

As urbanization accelerates, the urban heat island effect is becoming increasingly pronounced in medium and small cities. Therefore, investigating the urban heat island effect in small and medium-sized cities can provide reliable data for long-term monitoring of various levels of urbanization across China, which is crucial for developing green, low-carbon, and livable ecological cities. This study leveraged long-term MODIS land surface temperature data, delving into the temporal variations and spatial patterns of surface urban heat island intensity (SUHII) across 1444 counties in China from both annual and seasonal time scales, as well as from national and climatic zone spatial dimensions. Meanwhile, the primary reasons influencing SUHII changes were investigated. The results indicated that a significant upward trend in SUHII nationwide, with the exception for winter, and the most rapid increase was observed in spring. In different climatic zones, the mid-temperate, warm temperate, and northern subtropical zones experienced notable growth in spring and autumn, while the mid-subtropical to marginal tropical zones demonstrated a pronounced rise in all seasons. Furthermore, weak hot islands dominated in China, except in winter, although their proportion declined over time. Strong and moderate hot islands were on the rise, primarily in the south of the Qinling-Huaihe line at 34°N. Winter was mainly characterized by no clear cold/hot islands, concentrated in the warm temperature and northern subtropics, with weak hot islands expanding southward into temperature regions. Besides, over the 20 years, approximately 47 % of cities maintained stable cold/hot island levels, while 53 % underwent transitions, predominantly hot island level conversions.

The mean PM₁₀ concentrations recorded at these stations were 33.3 ± 0.5 µg/m³, 32.1 ± 0.4 µg/m³, and 27.4 ± 0.3 µg/m³, all remaining below the EU annual limit of 40 µg/m³.
