The recent rapid increase in urbanization has led to the inclusion of underground spaces in urban planning policies. Among the main subsurface resources, a strong interaction between underground infrastructures and groundwater has emerged in many urban areas in the last few decades. Thus, listing the underground infrastructures is necessary to structure an urban conceptual model for groundwater management needs. Starting from a municipal cartography (Open Data), thus making the procedure replicable, a GIS methodology was proposed to gather all the underground infrastructures into an updatable 3D geodatabase (GDB) for the metropolitan city of Milan (Northern Italy). The underground volumes occupied by three categories of infrastructures were included in the GDB: (a) private car parks, (b) public car parks and (c) subway lines and stations. The application of the GDB allowed estimating the volumes lying below groundwater table in four periods, detected as groundwater minimums or maximums from the piezometric trend reconstructions. Due to groundwater rising or local hydrogeological conditions, the shallowest, non-waterproofed underground infrastructures were flooded in some periods considered. This was evaluated in a specific pilot area and qualitatively confirmed by local press and photographic documentation reviews. The methodology emerged as efficient for urban planning, particularly for urban conceptual models and groundwater management plans definition.

<p><strong>Abstract.</strong> In urban planning, a common unit of measurement for population density is the number of households per hectare. However, the actual size of the households is seldom considered, neither in 2D nor in 3D. This paper proposes a method to calculate the average size of the household in existing urban areas from available open data and to use it as a design parameter for new urban development. The proposed unit of measurement includes outdoor and indoor spaces, the latter comprising both residential and non-residential spaces. As a test case, a to-be-planned neighbourhood in Amsterdam, called Sloterdijk One, was chosen. First, the sizes of “typical” households, as well as a series of KPIs, were computed in existing neighbourhoods of Amsterdam, based on their similarities with the envisioned Sloterdijk One plan. Successively, the resulting size of the household was used as a design parameter in a custom-made tool to generate semi-automatically several design proposals for Sloterdijk One. Additionally, each proposal can be exported as a CityGML model and visualised using web-based virtual globes, too. Significant differences among the resulting proposals based on this new unit of measurement were encountered, meaning that the average size of a household plays indeed a major role.</p>

The Eastern Economic Corridor project (EEC), which spans over three coastal provinces east of the Bangkok Metropolitan Area (BMA), aims to transform Thailand into a developed country progressively. The EEC project promises to influence its territory and surrounding areas. We aimed to monitor the urbanized directions at the BMA during 2015-2017 and explore whether the BMA’s urban expansion trend is related to the EEC. The results revealed that the built-up areas increased by 24,033 hectares (22.8%). The urban districts with high urban density slowly developed, while the rural districts tended to urbanize with a high urbanization rate, approximately 6.8% per year. The BMA urban areas mainly expanded to the east (14.9% per year) and southeast (21.6% per year) under partial impacts from the EEC infrastructure projects. The research findings represent a concept for assessing urban expansion and pointing to the regions of concern, which will be meaningful for urban planning and policymaking.

Intestinal parasites of dogs and cats are cosmopolitan pathogens with zoonotic potential for humans. Our investigation considered their diffusion in dogs and cats from northern Italy areas, specifically the metropolitan area of Milan and two micropolitan areas of neighboring provinces. It included the study of the level of awareness in pet owners of the zoonotic potential from these parasites. A total of 409 fresh fecal samples were collected from household dogs and cats for copromicroscopic analysis and detection ofGiardia duodenaliscoproantigens. The assemblages ofGiardiawere also identified. A questionnaire about intestinal parasites biology and zoonotic potential was submitted to 185 pet owners. The overall prevalence of intestinal parasites resulted higher in cats (47.37%−60.42%) and dogs (57.41%−43.02%) from micropolitan areas than that from the metropolis of Milan (dogs:P=28.16%; cats:P=32.58%). The zoonotic parasites infecting pets under investigation wereT. canisandT. cati,T. vulpis, Ancylostomatidae, andG. duodenalisassemblage A. Only 49.19% of pet owners showed to be aware of the risks for human health from canine and feline intestinal parasites. Parasitological results in pets and awareness determination in their owners clearly highlight how the role of veterinarians is important in indicating correct and widespread behaviors to reduce risks of infection for pets and humans in urban areas.

The present paper reunites in an objective synthesis data from forest management plans realized in the West Plain during 1995-2008. The study focused on stands situated around cities and in their construction perimeter in order to emphasise their contribution to the area’s long lasting development. The paper’s importance derives from the fact that urban areas are in a continuous development that will incorporate heavily nearby forests. As such, through their functions, forests contribute to the long lasting development of the entire metropolitan area to which they belong. All forests from the West Plain were divided in stand elements (species of a certain age that belong to a forest’s composition). The study has taken into account all stand elements from the area that belongs to the forest category from around cities. The large number of these stand elements (2107) offers a solid base for the different realized analyses. The paper’s results show that from the entire surface of forests with recreation functions located in the West Plain, 4.670 ha are occupied by Forests from around counties, cities and villages as well as forests located in their construction perimeter. The most widespread species from this type of stand is pedunculate oak (Quercus robur L.), which occupies 2072 ha. Forests from around cities from the West Plain are situated at altitudes between 80 and 400 m. The soils are predominantly common alvisol, while Arum-Pulmonaria is the most widespread flora. In the context of the long lasting development of urban areas with implications on nearby forests, the results and discussions of this article represent a first step towards knowing these forests and towards properly managing them in order to successfully fulfil their protection and recreational purposes.

Urban planning offers various design possibilities to solve fundamental challenges faced in urban areas. These include the need to physically renew old industrial and harbour riverside areas into liveable, inclusive and sustainable living spaces. This paper investigates the way urban planning policies have helped to renew the waterfront areas in the Lisbon metropolis in the past decades. For this purpose, the contribution of the European Union (EU) and national urban development plans over the past decades are analysed. The results demonstrate an intense renewal of the waterfront areas in the Lisbon metropolitan area (LMA), particularly in Lisbon over the past three decades into leisure, ecologic and touristic areas, vis-à-vis the previous industrial and harbour vocation.

This review presents historical transformation on urban planning approaches in the Tokyo metropolitan area. Urban areas in Japan have always been threated by urban conflagrations due to the high number of wooden structures. The Tokyo metropolitan area which was previously known as Edo until the Meiji Revolution in 1864. Dramatic changes in power was successful but few urban structure reformation occurred, and Tokyo was damaged by urban conflagrations in the Meiji, Taisho, and Showa Eras. The fervent wishes of Japanese urban planners centered on construction of fireproof urban areas. Such wishes accounted for little in actual policy, however, as witnessed to by the failure of Tokyo officials to construct fireproof urban architectures following the massive destruction left by World War II. In September 1959, the Ise-Wan (Ise Bay) Typhoon caused tremendous damage and left over 5,000 dead. As measures against such disasters, the Japanese government enacted the Disaster Countermeasures Basic Act in 1961. Howevers, measure against Earthquake-induced disasters were yet far from sufficient although Japan experienced hit by the Great Kanto Earthquake of 1923. In 1964, the Niigata Earthquake clearly demonstrated modern Niigata City's vulnerability to earthquakes despite its facilities for the National Sports Festival were equipped with modern technology, all of these facilities were destroyed. Reflecting such disasters, reexamination of measure against earthquake disaster began at coastal cities of Japan, which were constructed in post war time. This paper tracks developments in Japanese urban planning movement that the author took part in for about 20 years from 1964.

The effective, efficient and equitable policing of urban areas rests on an appreciation of the qualities and scale of, as well as the factors shaping, demand. It also requires an appreciation of the factors shaping the resources deployed in their address. To this end, this article probes the extent to which policing demand (crime, anti-social behaviour, public safety and welfare) and deployment (front-line resource) are similarly conditioned by the social and physical urban environment, and by incident complexity. The prospect of exploring policing demand, deployment and their interplay is opened through the utilisation of big data and artificial intelligence and their integration with administrative and open data sources in a generalised method of moments (GMM) multilevel model. The research finds that policing demand and deployment hold varying and time-sensitive association with features of the urban environment. Moreover, we find that the complexities embedded in policing demands serve to shape both the cumulative and marginal resources expended in their address. Beyond their substantive policy relevance, these findings serve to open new avenues for urban criminological research centred on the consideration of the interplay between policing demand and deployment.

Abstract Our paper focuses on Solidarity Purchase Group (SPG) participants located in a highly urbanized area, with the aim to investigate the main motivations underlining their participation in a SPG and provide a characterization of them. To this end, we carried out a survey of 795 participants involved in 125 SPGs in the metropolitan area of Milan (Italy). Taking advantage of a questionnaire with 39 questions, we run a factor analysis and a two-step cluster analysis to identify different profiles of SPG participants. Our results show that the system of values animating metropolitan SPG practitioners does not fully conform to that traditionally attributed to an alternative food network (AFN). In fact, considerations linked to food safety and healthiness prevail on altruistic motives such as environmental sustainability and solidarity toward small producers. Furthermore, metropolitan SPGs do not consider particularly desirable periurban and local food products. Observing the SPGs from this perspective, it emerges as such initiatives can flourish also in those places where the lack of connection with the surrounding territory is counterbalanced by the high motivation to buy products from trusted suppliers who are able to guarantee genuine and safe products, not necessarily located nearby.

Ongoing urbanization leads to steady growth of urban areas. In the case of highly dynamic change of municipalities, due to the rates of change, responsible administrations often are challenged or struggle with capturing present states of urban sites or accurately planning future urban development. An interest for urban planning lies on socio-economic conditions, as consumption and production of disposable goods are related to economic possibilities. Therefore, we developed an approach to generate relevant parameters for infrastructure planning by means of remote sensing and spatial analysis. In this study, the single building defines the spatial unit for the parameters. In the case city Belmopan (Belize), based on WorldView-1 data we manually define a city covering building dataset. Residential buildings are classified to eight building types which are locally adapted to Belmopan. A random forest (RF) classifier is trained with locally collected training data. Through household interviews focusing on household assets, income and educational level, a socio-economic point (SEP) scaling is defined, which correlates very well with the defined building typology. In order to assign socio-economic parameters to the single building, five socio-economic classes (SEC) are established based on SEP statistics for the building types. The RF building type classification resulted in high accuracies. Focusing on the three categories to describe residential socio-economic states allowed high correlations between the defined building and socio-economic points. Based on the SEP we projected a citywide residential socio-economic building classification to support supply and disposal infrastructure planning.

The impact of the reduced atmospheric emissions due to the COVID-19 lockdown on ambient air quality in the Po Valley of Northern Italy was assessed for gaseous pollutants (NO2, benzene, ammonia) based on data collected at the monitoring stations distributed all over the area. Concentration data for each month of the first semester of 2020 were compared with those of the previous six years, on monthly, daily, and hourly bases, so that pre, during, and post-lockdown conditions of air quality could be separately analyzed. The results show that, as in many other areas worldwide, the Po Valley experienced better air quality during 2020 spring months for NO2 and benzene. In agreement with the reductions of nitrogen oxides and benzene emissions from road traffic, estimated to be −35% compared to the regional average, the monthly mean concentration levels for 2020 showed reductions in the −40% to −35% range compared with the previous years, but with higher reductions, close to −50%, at high-volume-traffic sites in urban areas. Conversely, NH3 ambient concentration levels, almost entirely due the emissions of the agricultural sector, did not show any relevant change, even at high-volume-traffic sites in urban areas. These results point out the important role of traffic emissions in NO2 and benzene ambient levels in the Po Valley, and confirm that this region is a rather homogeneous air basin with urban area hot-spots, the contributions of which add up to a relatively high regional background concentration level. Additionally, the relatively slow response of the air quality levels to the sudden decrease of the emissions due to the lockdown shows that this region is characterized by a weak exchange of the air masses that favors both the build-up of atmospheric pollutants and the development of secondary formation processes. Thus, air quality control strategies should aim for structural interventions intended to reduce traffic emissions at the regional scale and not only in the largest urban areas.
