Results from studying urbanized territories highly depend on approaches and methods of interpreting data obtained in the course of investigations. A case study was made in the industrial city of Usolye-Sibirskoe (Irkutsk oblast, RF) to investigate and map the current ecological-and-biochemical status of soil cover affected by urbanization and technogenesis. T. V. Aristovskaya’s and M. V. Chugunova’s rapid method was used to reveal high indicators of the level of alkaline-acid conditions and biochemical activity of urban soils. The mapping enabled identification of the local features of the urban territory. A considerable part of it is occupied by soils with weak alkaline pH index (7.3–8.0). In absolute values, it is 6083.3 ha, or 77.2 %. The study determined a high and very high level of the soil biochemical activity. They occupy a large area of 6079.2 ha, i.e. 76 % of the city. A substantial increase in soil biochemical activity can lead to loss of a biogenous element, nitrogen, and this cannot be regarded as a positive phenomenon. Experimental data on the SBA – рН system for the residential zone of the city made it possible to determine a close correlation between them to be statistically significant.

Presented are the isolines maps for the distribution of inhomogeneous values of acid-alkaline medium and biochemical activity levels of soils in the industrial city of Bratsk in the settings of Eastern Siberia. The maps were constructed from point measurements in the geoinformation environment by the IDW Nearest Neighbors method. The soil biochemical activity was analyzed by using the proximate method according to T. V. Aristovskaya and M. V. Chugunova. It is shown that the activity of urban soils varies from strong to moderate. The soils with high activity occupy 75,3 % of the total area of the city. The acid-alkaline conditions of soils are transformed considerably toward the alkaline side. On the hole, the alkaline and highly alkaline soils occupy 96% of the territory. A high level of soil biochemical activity has been revealed. This study deals with the transformation of nitrogen-containing organic compounds leading to a loss of biogenic nitrogen by the soil.

The congress industry is a young, dynamic industry, which is growing and maturing at a rapid rate. It is now a truly international industry, witnessing huge investments across all continents. Due to economic and other benefits of a more intangible nature, the number of congress destinations and venues worldwide is growing. In order to provide the sustainability of congress destinations and venues, it is important to examine congress delegates’ experience, their overall satisfaction as well as behavioural intentions regarding destination. This study was conducted in the city of Novi Sad, which is after Belgrade the most important international meeting destination in Serbia. The purpose of this study is to examine the experience and overall satisfaction of the attendees at international congresses held in Novi Sad. Also, the relationship between overall satisfaction, word-of-mouth and intention to return were examined. A questionnaire survey was used as an instrument for the study. The collected data were analyzed using SPSS standard package. The results showed high level of attendees’ satisfaction with the congress elements and with destination choice. Also, the results confirmed that Novi Sad has a great potential for development of congress tourism, as the majority of the respondents show great interest to visit Novi Sad again and they would recommend city as a meeting destination. The results of this study are valuable for congress centre managers and for destination management organizations.

This chapter presents a case-study of tourism gentrification in a fishing town in Algarve, South Portugal. Olhão is a former industrial city that saw much of its fishing industry disappear since the 1980s. Over the last few years, hundreds of foreigners have moved into its historic centre. This rapid influx of citizens to derelict neighbours mostly comprised of old retirees and few active fishermen prompted a gentrification process. Olhão now faces the threat of mass displacements of its older and most vulnerable citizens, a fact that is worrying the foreigners that criticize the touristification of the city, with rents at historical highs and landlords forcing out the Portuguese residents in order to promote short-term rentals to tourists. The chapter presents the results obtained from an extensive mixed-methods research, ending with some notes about the future of the city and the implications that can be taken from this case.

Polityka parkingowa należy do ważniejszych wyzwań w rozwoju współczesnych miast w zakresie transportu. Jednym z narzędzi kształtowania tego zjawiska w miastach jest wprowadzanie stref płatnego parkowania, które mają zwiększać rotację pojazdów oraz zachęcać do korzystania z innych środków transportu w codziennych dojazdach. Jest to szczególnie ważne w kontekście centrów miast. Wdrażanie stref płatnego parkowania stanowi często stosowane rozwiązanie w dużych miastach, rzadziej w średnich i małych. Celem tego badania jest analiza sposobu docierania mieszkańców średniego miasta – Tczewa – do centrum (Starego Miasta) oraz ocena możliwości wprowadzenia strefy płatnego parkowania. Badanie przeprowadzono metodą ankiety, posługując się techniką PAPI (Paper and Pencil Interview), w którym zebrano 375 odpowiedzi. W przeprowadzonym badaniu ankietowym wykazano, że istnieje duży poziom akceptacji społecznej dla możliwości wprowadzenia strefy płatnego parkowania w analizowanym przypadku. W badaniu wykazano ponadto, że znaczną większość użytkowników centrum stanowią osoby docierające tam pieszo. Potwierdzono także, że mieszkańcy są skłonni nie tylko zapłacić za parkowanie w centrum miasta, ale także przejść pewien dystans pieszo od miejsca postojowego do celu podróży. Niniejsza praca może mieć charakter aplikacyjny i stanowić wskazówkę dla innych miast o podobnej wielkości i strukturze, które zamierzają wprowadzić strefę płatnego parkowania lub innego rodzaju ograniczenia ruchu samochodów. Mobility in the centre of a medium-sized city in the perspective of the prospective introduction of a paid parking zone – a case study of Tczew Parking policy is one of the more important challenges in the development of modern cities in terms of transport. One of the tools for shaping this policy in cities is the introduction of paid parking zones, which are intended to increase vehicle turnover and encourage the use of other means of transport for everyday commuting. This is particularly important in the context of city centres. The introduction of paid parking zones is a common solution in large cities, less so in medium-sized and small ones. The aim of this study is to analyse how residents of a medium-sized city – Tczew – travel to the centre (Old Town) and to assess the possibility of introducing a paid parking zone. The study was carried out through a survey, using the PAPI (Paper and Pencil Interview) technique, with 375 responses collected. It showed that there is a high level of public acceptance for the possible introduction of a paid parking zone in the case under consideration. The study also yielded that the vast majority of users of the centre are people who get there on foot. It was also confirmed that residents are not only willing to pay for parking in the city centre, but also to walk a certain distance from their parking space to their destination. This work can be applied as a guide to other cities of similar size and structure that intend to introduce paid parking zones or other types of car traffic restrictions.

In this paper, we study the consequences of neoliberal urban policy, in terms of the segregation and social changes experienced in the Cabanyal neighborhood located in Valencia, Spain. In doing so, we analyze the process of residential mobility that has affected the neighborhood during the last decade, resulting in a segregation of space. This neighborhood had been affected, since 1988, by an urban project that was to bring about its partial destruction. Despite having been stopped, the project has caused a dynamic of physical and social degradation of the neighborhood against which the local government has only very recently started to intervene. Using microdata from the Residential Variation Statistics provided by the Statistical Office of the City of Valencia, we analyze the demographic profile of the mobility inside the Cabanyal neighborhood and also the origin of the arrivals and the destination of the departures from 2004–2016. The aim is to identify the territorial pattern of the socio-demographic changes that have affected the neighborhood. The results indicate that during the period under analysis, in which the area was affected by the urban project, a progressive loss in the Spanish population was occurring, as well as a substitution of non- EU immigrants, who were predominant at the beginning of the period, with EU immigrants. This process has produced a high level of residential segregation, since immigrants from the European Union are viewed more negatively than immigrants from outside of the European Union, which, along with their lower level of education and employment in low-skilled and poorly paid jobs, makes their social integration and interaction more difficult.

Socialist cities were assigned a vital role in the countries of the Eastern Bloc. Their establishment was primarily due to accelerated industrialisation designed to enhance the economic and political strength of the communist system worldwide. In addition, they were also to function as communist melting pots, providing inspiring spaces for the emergence of the archetype of the new socialist man and its model community. It is not surprising that socialist cities were fundamentally shaken by the change of the political system in the 1990s, which challenged their relation to industrialisation and the industrial heritage. Through the case study of two socialist cities in Hungary, Ózd and Dunaújváros (the latter formerly called Sztálinváros, Stalin-City), the paper aims to present the wavering evaluation of the industrial heritage over the three decades following the regime change and showcase how its various values became finally accommodated in the transformation of the cities. In Ózd, the monument protection and high-level reconstruction of the buildings of the former ironworks’ reading society and managers’ casino, as well as the innovative reuse of workshops like the Digital Power Plant and the National Film History Theme Park provide excellent examples of industrial heritage-based urban development. In Dunaújváros, the recent monument protection of the outstanding buildings of socialist realism and the newly-elaborated tourist route presenting their values facilitate understanding the past and improve the attractivity of the city. Methodologically, this paper will focus on comparative analysis instead of plain description in order to expose the multiple developments which were leading to the appreciation and utilisation of industrial heritage promoting sustainability in these two cities.

A strategic city located on the northern coast of Sumatera Island known as Dumai City. This city is a growth and industrial city that always increase everyday economically. This city faces the flood problem that not only from the excess water from the rain, but also from the phenomena of seawater tidal. The tidal should not reach the mainland for the ideal situation, but the urbanization and development problem made it happen. Field observation and satellite data analysis shows the problem that happened in this city, also find out the solution how to make the seawater tidal will not being the flood when it occurs. The flood caused by the inadequate drainage condition is exacerbated by the low awareness of people who still do not maintain cleanliness, a lot of garbage that accumulates in the drainage causing the process of water flow to be inhibited. Geologically, the base rock of Dumai City consists of sand and peat which logically is a good system to absorb water because sand and peat are materials that have high porosity. Topographically, the city of Dumai is at an average height of three meters above sea level, so in fact, this city could be spared from the flood caused by the tide when it occurs. The solutions that can be proposed for this city are making the rivers being clean with normalization, well-designed drainage, Watergate and making an artificial lake for sinking the tidal seawater.

Abstract. The concentrations of gases and properties of aerosol particles have been measured at the mountain site of Altzomoni approximately equidistant from Mexico City, Puebla and Cuernavaca, at an altitude of 4010 m. At this location there is a diurnal transition from local to regional mixed layer air whose properties depend on prevailing winds and larger scale circulation. Three days during March 2006 have been evaluated during which time the synoptic scale air flow was from the east, southeast and southwest. In general the properties of gases and particles were similar when the regional mixed layer (RML) was below the research site, regardless of the direction of flow. When the RML reached the site, the highest concentrations of CO, O3 and aerosol particles were from the east, decreasing as the flow shifted to the southeast then to the southwest. The maximum concentration of condensation nuclei (CN) was greater than 25×10−3 when winds were from the east. The highest mass concentrations of organic matter (OM), sulfate (SO4−), and Nitrate (NO3+ were 80, 4 and 8 μg m−3, at standard temperature and pressure in air from the east. The mass concentration of OM in the RML was greater than 70% of the total mass, regardless of the air mass origin. This compares to less than the 60% that has been reported for Mexico City. At night, the mass fraction of sulfate went up by a factor of ten from the daytime value when air arrived from the east. The relationship between the CO and OM suggests that the majority of the daytime OM is from biomass burning and at night it is from wood burning. Whereas the maximum CO at Altzomoni, 0.35 ppm, was approximately one tenth of the CO measured at the same time in the center of Mexico City, the maximum O3 of 120 ppb was approximately the same as in the city. The maximum nighttime values of O3 was 60 ppb, indicating the presence of residual pollution. From these results we conclude that even though Mexico City is the second most populated city in the world, with an associated high level of pollution, there are other significant sources of pollution in Mexico that contribute to the mixture of emissions that are dispersed throughout the region. This mixture rapidly erases the signature of a unique Mexico City "plume" and suggests that the environmental impact of this region should be considered as one that stems from a large area source rather than a single megacity.
