Aquatic phytoremediation is a nature-based solution. It has the potential to provide efficient, adaptable, and multi-targeted treatment of polluted waters. The aim of this research is to evaluate non-mechanized, low-cost onsite treatment of waste water intrusions. It includes an experimental set up with three replicates. Each consists of a modified flow pattern under outdoor conditions. Experimental set up A and B were provided with macrophytes, water lettuce and duckweed, respectively, with plant coverage at 50% and 90%. Experimental set up C was a controlled set up without macrophytes. The highest removal of BOD, COD and Total solids by using water lettuce were observed to be 89%, 77% and 38.5%, respectively. By using duckweed, the highest removal of BOD, COD and Total solids were observed at 88%, 66% and 27.59%, respectively. Removal was also observed in Set up C for BOD, COD and Total solids; its efficiency was 48%, 47% and 25%, respectively. Set up A can be recommended for treating wastewater intrusion, so that wastewater will purify to a to satisfactory to disposal standard level before mixing in river water. The area available in the stream itself can be used as a treatment zone.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44513804","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, there is close to no knowledge available about how ICT-based smartphone apps meant for day-to-day trip planning tasks are being used across various user groups and how they influence travel outcomes, especially in Indian cities. Therefore, this study is an effort to close this gap by gathering data from the city of Bhopal and carrying out an exploratory statistical analysis on the usage of smartphone apps for different types of trip planning purposes, as well as their influence on travel outcomes. The study provides empirical evidence of relationships between smartphone app usage for trip planning (such as departure time, destination selection, mode selection, route selection, communicating and coordinating trips, and performing tasks online rather than visiting) and the resulting travel outcomes, such as kilometres travelled by vehicle (for purposes, such as work/education, shopping, and recreation), social gatherings, new destinations, and group trips. The chi-square test has been used to test and interpret several socioeconomic variables that could influence this relationship, such as gender, age, income, etc. The study’s findings provide important behavioural insights that may be useful in policy discussions.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49260309","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}

Therefore, urban growth that considers eco-hydrological principles can foster sustainability in cities. This work projected three possible urban development patterns for San Luis Potosi’s micro-watershed, characterized by flood design estimations and different urban densities considerations. The selected micro-watershed is located in the western periphery of the city, which is in the process of being urbanized. As the study site is in a semi-arid region where data are scarce, this research used the rational method and the software Rhinoceros for modeling urban scenarios. Models included criteria that allow for comparing a traditional urbanization perspective of what is expected (without green areas) with alternatives that consider green areas as well as different urban densities and that favor eco-hydrological principles. The high urban-density (green area) scenario shows a sustainable alternative for the micro-watershed by which eco-hydrological principles are fostered, as well as an alternative to high urban density without undermining real-estate profitability. Although calculations could be strengthened by using more local data, the results provide insights for urban planners and developers on the sustainable transformation of the micro-watershed.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44877168","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}

This study aims to investigate several facets of urban resilience and densification before analyzing their mutual relationship. Focusing on ecological, social, economic, and physical elements of urban resilience on the one hand and population density, residential density, built-up area ratio (BAR), and parcel density on the other, a combination of spatial and quantitative methodologies is applied. Our empirical investigation revealed that the spatial distribution of all resilience indicators is varied. In other words, the cumulative form of urban resilience indicators has a different significance than the individual version. Similarly, different types of density have varying orientations and degrees of connection with measures of resilience that should be evaluated in empirical investigations. In addition, our research revealed that density has a stronger relationship with social and physical resilience than with ecological and economic resilience. The findings drawn from this research have the potential to inform the design of secure, resilient cities across a range of spatial dimensions.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44766210","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}

Most commonly used for Transit Oriented Development (TOD), the node–place model checks the balance between transportation systems and land use. While previous node–place research focused mostly on rail transportation, this research focuses on highway accessibility to assess future growth and urban development. To gain insight into the development dynamics, the node–place model is utilized with a focus on the I-287 Corridor located in New York, U.S. The node function describes the transport activity and connectedness of the area to other places of interest, which measures the accessibility of the locations, the type of connections, and the number of directions connected. In addition, population, number of workers in the labor force, and degree of a functional mix are also considered for place values. According to the results, four exits are in balanced areas with stable traffic and customer flow support and strong support from local government departments. This case study contributes to a deeper understanding and evaluation of highway accessibility and provides an exciting assessment tool for sustainable development planning. While node–place models cannot predict development, they can be used to understand development dynamics better.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45291364","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}

By a gradual transformation of its grounds, infrastructure, and social fabric, the long-term goal of the DDRC is to function as a tangible model that can be experienced and replicated as a whole or in parts in the city or elsewhere. The paper discusses the goals, methodologies and strategies introduced during the project aiming towards the regenerative transformation of the institution that drew inspiration from permaculture principles, nature-based solutions and a net-positive design perspective.

This study contributes to the literature on environmental culture and practical solutions by better understanding households’ behaviours and motivations for (i) sorting waste, (ii) contributing to the environmental fund and (iii) relocating. The questionnaire-based interview method was used to randomly collect information from 730 households in 25 provinces in Vietnam during February 2022. Bayesian regression models, coupled with the mindsponge mechanism, were applied to analyse the data. The results showed that people’s strategies and responses to plastic waste pollution vary: 38.63% of respondents were sorting waste at home, 74.25% of households agreed to contribute to the environmental fund, and 23.56% had a plan to relocate for a better living place. The households’ strategies and intentions were driven by several structural and contextual factors such as age of household head, income, care about the environment, and the perceived effects of polluted waste. More importantly, communication was a robust variable in sorting waste decisions, which suggested that better communication would help increase people’s awareness and real actions in reducing plastic waste and ultimately improving the environment. These findings will benefit the ongoing green economy, circular economy, and green growth transition toward more sustainable development, particularly in developing and fast-population-growing countries.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47733387","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, in recent decades more and more evidence has shown that unaffordable housing is the consequence of monetary policy. Most of the previous empirical studies have been based on econometric analyses, which make it hard to eliminate potential endogeneity biases. This cross-country study exploited the two global interest rate shocks as quasi-experiments to test the impacts and causality of monetary policy (taking real interest rates as a proxy) on house prices. Global central banks’ synchronized reduction in interest rates after the outbreak of the COVID-19 pandemic in 2020 and then the global synchronized increase in interest rates after the global inflation crisis in 2022 provided both a treatment and a treatment reversal to test the monetary policy hypothesis. The stylized facts vividly reveal the negative association between interest rate changes and house price changes in many countries. This study further conducted a ten-country panel regression analysis to test the hypothesis. The results confirmed that, after controlling for GDP growth and unemployment factors, the change in real interest rate imposed a negative effect on house price growth rates. The key practical implication of this study pinpoints the mal-prescription of harnessing monetary policy to solve housing affordability issues, as it can distort housing market dynamics.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44674914","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}

Especially, vulnerable populations, such as seniors and low-income residents, have lower access to personal vehicles and therefore are mobility-challenged. Being challenged in terms of mobility has effects on the health of the population concerned as this constraint not only limits economic activity that leads to perpetuation of lower means and poverty but also social activity that leads to physical and mental isolation. In a study of Michigan public and nonprofit transit systems, the customer satisfaction, particularly of vulnerable populations, with transit services is analyzed through on-board intercept surveys.
