Recent development dynamics of urban centers forced administrations to deal more frequently with problems linked to the inability of traditional sewer systems to manage rainwater in a sustainable and effective manner. Currently, several laws require compliance with the quantitative and qualitative stormwater limits to be discharged into watercourses but, in parallel with a “regulatory” approach, integrated strategies are increasingly being developed. A fundamental role is carried out by Sustainable Drainage Systems (SuDS), whose basic principle is the management of rainwater at the source, through the implementation of prevention, mitigation and treatment strategies. This study, starting from a project proposal made by different Italian firms and funded by PoliS-Lombardia, aims to assess the benefits deriving from the widespread application of SuDS in the Sesto Ulteriano industrial area, through a comparison between a scenario that represents the current configuration of the drainage network, and an ideal scenario where SuDS are taken into consideration. SWMM5 software was used, in order to simulate the behavior of the drainage network in contexts without and with SuDS, after the construction of the synthetic rainfall data sets. Although only event scale simulations have been conducted so far, the encouraging results suggest that these systems really contribute can to mitigating the effects of flooding in urban areas.

Over Time

<p>Recently, particularly invasive urbanization dynamics, resulted into a substantial increase in the urban impervious surface that forced the administrations to deal more frequently with the inability of the traditional drainage systems to manage stormwater in a sustainable and effective manner. Worldwide, integrated approaches, such as Sustainable Drainage Systems (SuDS), whose basic principle is the management of rainwater at source through the implementation of prevention, mitigation and treatment strategies, are increasingly being developed.</p><p>The project aims to assess the benefits, in terms of reduction of floods, deriving from the widespread implementation of SuDS in an industrial area of about 300 ha in northern Italy and to analyse their behaviour under local climatic conditions. For this purpose, in absence of rain gauges in the case study area, analyses were carried out to obtain reliable and continuous rainfall data from all weather stations closest to the basin. Therefore, 10 years of rainfall data (2009-2018), recorded at 15 minutes timesteps from 10 station, have been acquired by the Regional Agency for Environmental Protection of the Lombardia Region and Inverse Distance Weighting has been used as a methodology of interpolation to obtain precipitation for the area of interest.</p><p>Critical precipitation scenarios, both annual and event scale, have been identified to evaluate the performance of SuDS during significant rainfall periods or events. For this reason, it was considered appropriate to extract from the complete dataset the year characterized by the maximum precipitation amount (1515.57 mm), the rain events with the maximum intensity in an hour (5.23 mm/h), with the maximum overall intensity (7.36 mm/h) and with the highest return period (5 years with a 6.87 mm/h intensity).</p><p>SWMM5 modelling allowed to compare the performance of the sewer system of the basin (overall 1148 nodes, 1141 pipelines for a total of 36 km of network) in a “traditional” scenario, without integrated strategies, and after the implementation of  green infrastructures (about 10% surface area and located in the basin in accordance with the current structure of the urban agglomeration).</p><p>The results, assessed in terms of reduction of different parameters such as runoff coefficient (on average 12% for the year and 39% for the event analysis), maximum flow in the pipelines (on average 3% and 31% respectively), maximum total inflow in the outfalls (on average 7% and 40% respectively) and node flooded (on average 23% and 57% respectively) following the implementation of SuDS, suggest in the first instance that these systems can give their contribution in the mitigation of the effects of flooding in urban areas. Indeed, analyses aimed at investigating punctually over time flow and volume in the outfalls conducted so far, brought about no extremely positive results and the performance of SuDS seems to be particularly challenged by severity of rainfall events.  As future aspects, this research strives to assess the performance of sustainable drainage systems under common rainfall scenarios and to establish, through an analysis of the climate change effects and the creation of rainfall data projections, the performance of these systems also over time.</p>

Real Scenario

The fast transformation of the urban centers, pushed by the impacts of climatic changes and the dramatic events of the COVID-19 Pandemic, will profoundly influence our daily mobility. This resulted scenario is expected to favor adopting cleaner and flexible modal solutions centered on bicycles and scooters, especially as last-mile options. However, as the use of bicycles has rapidly increased, cyclists have been subject to adverse conditions that may affect their health and safety when cycling in urban areas. Therefore, whereas cities should implement mechanisms to monitor and evaluate adverse conditions in cycling paths, cyclists should have some effective mechanism to visualize the indirect quality of cycling paths, eventually supporting choosing more appropriate routes. Therefore, this article proposes a comprehensive multi-parameter system based on multiple independent subsystems, covering all phases of data collecting, formatting, transmission, and processing related to the monitoring, evaluating, and visualizing the quality of cycling paths in the perspective of adverse conditions that affect cyclist. The formal interactions of all modules are carefully described, as well as implementation and deployment details. Additionally, a case study is considered for a large city in Brazil, demonstrating how the proposed system can be adopted in a real scenario.

In the industrialized northern hemisphere we are assaulted daily with evidence of the deteriorating quality of the human environment: Rivers are closed to fishing because of dangerous levels of contamination; the safety of important foods is challenged; the foul air that major urban areas have been forced to endure is now spreading like an inkblot into surrounding areas. Lack of early concern about the implications for the environment of the widespread application of modern technology has allowed the problem to grow rapidly into a critical domestic and international issue.

The Impact

Botswana like other developing countries faces a problem of acute shortage of housing, particularly for low-income urban families. The current housing problems are the outcomes of the economic, demographic and social changes which the country has experienced since independence in 1966. In particular the urbanization process which surfaced in the early 1980?s. The government has sought to cope with the problem of low-income urban housing by establishing a Self-Help Housing (SHHA) program in the main urban centers. The evaluation findings reveal that, on the whole, the impact of the SHHA approach on the improvement of low-income urban housing has been unsuccessful. The major problems of the scheme are lack of serviced land and inadequate finances for plot development. This has been exacerbated by the high urban development standards which are out of the reach of low-income urban families. The evaluation study also reveals that, there are some indications of non low-income urban households living in SHHA areas. The available evidence reveals that the number of those people in SHHA areas is not as big as has been speculated by most people in the country. However this paper calls for more investigation in this issue and a need for more tight measures to control this illicit practice. The major conclusions are that housing policies in Botswana are not supportive of the general housing conditions in low-income urban areas. Therefore there is a need for urban planners and policy makers of Botswana to take more positive action towards the improvement of low-income urban areas. This would require pragmatic policies geared towards the improvement of those areas. .

The explosive development of the human society in contrast to the limited character of resources determines the need for successful implementation of mathematic models in the decision-making process concerning the use of available resources. The oil industry includes a series of global processes such as mining, extraction, refining, transport (road, rail, ship and pipeline) and oil products. The products of this industry with the highest degree of utilization are gasoline and diesel but the portfolio is much broader, kerosene, bitumen, fuel and raw materials for other chemicals such as solvents, pesticides, fertilizers and materials plastic. The oil industry comprises three major areas: "upstream" extraction; refining - "midstream" and transportation and marketing of downstream products. In most cases refining is considered to be part of downstream, Oil and petroleum products are essential for many industries and their importance is vital in maintaining and developing the industrial area in the current configuration.

Geographic information systems can be defined as a intelligent tool, to which it relates techniques for the implementation of processes such as the introduction, recording, storage, handling, processing and generation of spatial data. Use of GIS in urban planning helps and guides planners for an orderly development of settlements and infrastructure facilities within and outside urban areas. Continued growth of the population in urban centers generates the need for expansion of urban space, for its planning in terms of physical and social infrastructures in the service of the community, based on the principles of sustainable development. In addition urbanization is accompanied with numerous structural transformations and functional cities, which should be evaluated in spatial context, to be managed and planned according to the principles of sustainable development. Urban planning connects directly with land use and design of the urban environment, including physical and social infrastructure in service of the urban community, constituting a challenge to global levels. Use of GIS in this field is a different approach regarding the space, its development and design, analysis and modeling of various processes occurring in it, as well as interconnections between these processes or developments in space.

Limited Testing

The Comprehensive Sickle Cell Centers were established in 1972 to test, educate, counsel, and research sickle cell anemia and related hemoglobinopathies. Standards and protocols for testing, education, and research were readily established because similar procedures and methods were already in operation at the institutions where the centers were located. The most difficult and still the most controversial program to provide is counseling. It became evident, early, that there is no universally accepted method for informing carriers of abnormal Hb S about their results. Centers located in large urban areas with a limited testing radius do not face the same problems as centers located in rural areas where the testing radius may cover an entire state or several states. Individual, or one-on-one, counseling of persons with trait results appears to be successful for urban centers where the individual may be called to the center and given information. But, in a rural setting, it is not feasible for the center to ask a person to travel 350 miles to be told he or she has nothing to worry about. And it is not cost-effective to send a caseworker 350 miles to say the same thing. It must, therefore, be concluded that each agency or center must adopt counseling methods that meet its specific needs. Each program must be flexible, imaginative, and creative and must successfully and accurately deliver information about being a carrier for the sickle gene or other hemoglobinopathy and its implication and significance for patients and their future offspring. To do this, we must first look at the problems facing us.

The 21st century is an urban world. Strategies that aim to tackle the urban material challenge and promote circular economy are necessary to achieve sustainable development. Having established the importance of circular economy towards sustainable development, this study presents applicable strategies to reduce consumption and promote circularity specifically in urban centers. Main strategies may be categorized into three areas: reducing material use through better design, efficient manufacturing and processing, and more intensive recycling. For materials use reduction, dematerialization, appropriate design based on product service lifetime, design for X principles and extended producer responsibility are identified as prominent design approaches or policies. For effective manufacturing and processing, the implementation of best available technologies and additive manufacturing were identified to have potential significant impact. For end-of-life phase management, differences between upcycling, recycling, and downcycling require targeted industry-specific policies.

Building Conversion

South Korea has industrialized and urbanized rapidly since the 1970s, and subsequently, the historic downtown areas of major cities have been hollowed out as the population and industry have become concentrated in urban centers. Based on the Urban Decline Indicators of Korea, in accordance with the Urban Revitalization Act of the South Korean government, a comparative analysis of the population changes, office vacancy rate, building aging rate, decrease in the number of industries and employees, and housing supply and demand in historic downtown areas and new urban areas of six major South Korean cities demonstrated that all six historic downtown areas have declined significantly. Currently, little research is available in South Korea on the expansion of urban living and the inflow of urban residents through office-to-residential building conversion. Therefore, this study explores the expansion of urban residences to revitalize these historic downtown areas. To this end, this study examines the feasibility of converting poorly functioning, vacant offices in historic downtown areas into residential spaces to present a sustainable strategy for their complexation. This study finds that office-to-residential building conversion is a sustainable way to recover urban space and grow the population and industry in historic downtown areas.
