The results show that the overheating risk differs significantly between the regions. It is very low for the region of Hamburg, moderate for Dresden and Potsdam and highly critical for Stuttgart. The indoor heat load is at least more than doubled if the building is located in the city centre instead of its surroundings or if future climate conditions are applied.

Focusing on Addis Ababa, we conduct a robust policy analysis of urban government response. Our main finding is that Addis Ababa’s environmental challenges are primarily a result of urban development and inadequate planning and policy enforcement. Environmental challenges are exacerbated by rapidly intensifying climate impacts, but not driven by them. Improved city-level policy responses can potentially mitigate many of Addis Ababa’s current environmental challenges and prepare the city to weather future ones. We highlight four areas of policy weakness: (1) ineffective or absent policies concerning green space; (2) the exclusion of informal settlements from ongoing resilience planning efforts; (3) limited public trust and transparency; and (4) a lack of coordination across the multiple agencies in Addis charged with planning. Holistic, multi-stakeholder planning is inhibited by a lack of collaboration, limited stakeholder participation, and a reluctance to engage in productive dialogue.

The objective of this study is to analyze the quality of treated wastewater (TWW) using treated wastewater quality index (TWWQI). Treated wastewater samples were taken at the influent and effluent of the wastewater treatment plant located within BLIP. The physico-chemical properties of the water samples from BLIP were analyzed at the third-party laboratory. The result showed that the aggregate TWWQI value falls under the category of <em>very poor</em> water for urban irrigation agriculture (UIA) use. This <em>very poor</em> water quality grade attributes 85 % to the presence of heavy metals, 4 % to nutrients load, 8 % to saline condition contributors and 4 % to miscellaneous contaminants. Discrete analyses of the indices for heavy metals, nutrient loads, saline condition contributors and miscellaneous contaminants shifted the water quality from <em>very poor</em> to <em>very polluted</em>, <em>excellent</em>, <em>poor</em> and <em>good</em> for UIA use respectively. Though the aggregate TWWQI is of very poor category for UIA use, the treatment plants of BLIP exhibited contaminants removal efficiencies of between 30 and 100 % with aggregate removal efficiency of 58 %. Results also revealed that there were contaminants that exhibited higher effluent values than influent after treatment indicating the failure of BLIP’s treatment plants to remove these contaminants. In conclusion, treated wastewater from BLIP, falls under very poor water category for use in irrigation agriculture where Cr<sup>+3</sup>, Cl<sup>−</sup> and TDS have contributed most in that order. Therefore, BLIP should upgrade and optimize its treatment plants to increase the removal efficiency for the respective contaminants.

Consequently, concerned waste pickers may increase their income and avoid the constraints of picking up recyclables in high-occupational-risk areas. Additionally, it may reduce the volume of unsorted garbage in the community. According to the findings of case studies, the developed model could obtain an optimal solution or acceptable approximate solution in a short timeframe.

However, the rising impact of human-induced land-use changes on ecosystem services (ES) poses a major challenge to the urban environment. This study focuses on scenario development for nature-based solutions (NbS) in a European town with its intense development area. The concept is exemplified in a town in Croatia, Grad Velika Gorica (GVG), that like many others cities undergoes urbanisation processes with limited resources. It serves as a showpiece for the influence of NbS, in particular street trees along various paths.</p><p>Using spatial analysis and modelling, the approach explores NbS for future urbanisation. The results, supported by quantitative analysis, show that 49% of cycle lanes and footpaths in GVG can be shaded by strategically planted street trees. The shading scenario analysis provides a nuanced perspective on the potential of NbS, offering insights into the key tasks for a climate-resilient city and opportunities towards equitable, green and healthy urban areas.</p><p>In the context of urbanisation processes and climate adaptation, the study is in line with the overarching objectives of the European Commission which emphasises the need for sustainable NbS alternatives to address environmental challenges. The findings contribute to the framework of informed decision-making towards urban climate resilience. It also supports the pursuit of a sustainable local governance for climate-adjusted environmental quality in urban planning. As towns and cities grapple with the imperative of balancing urban development with environmental protection, this research highlights the central role of NbS, particularly street trees, in shaping climate-resilient and more sustainable urban environments for human well-being in cities.</p></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"23 ","pages":"Article 100154"},"PeriodicalIF":3.3,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S259025202400014X/pdfft?md5=10a122354208e813e28f9309a9be916a&pid=1-s2.0-S259025202400014X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141325859","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}
