The article analyzes the processes of suburbanization and transformation of the spatial structure of the city of Ulan-Ude. Modern trends in the growth of Western and historical factors of development, due to socio-economic and historical factors of development. In the 1990s-2000s, because of the decline in agriculture and, as a result, the lack of jobs, the rural population began to migrate massively to the Buryat Republic’s capital. However, the prices for houses and apartments in the city center were unbearable for many migrants, so the purchase of land plots and the construction of houses were affordable for many. The estrangement of agricultural lands and their inclusion in residential areas allowed the city of Ulan-Ude and suburban areas to somewhat expand the territory of settlements and create a huge number of GNPP (gardeners non-profit partnership) and DNPP (dacha non-profit partnership). The city and suburban areas were not ready for such a flow and were not able to provide the newly arrived migrants with social, road transport and communal infrastructure. As a result, the city was surrounded by a suburbia almost devoid of any infrastructure. There are some elements of false urbanization or squatter area, which is a type of urbanization in which the urban population rapid growth is not accompanied by a commensurate increase in urban functions. In recent years, the growth rate of suburban settlements has decreased, mainly due to mortgages, which have become more affordable for the population and the growth of multi-storey construction. In addition, the village is slowly depleting the human resources that feed the city and the suburbs. In other words, those who wanted to move to the city have already moved

A Yellow-legged Gull catching a Feral Pigeon, flies to a nearby small lake and kills him drowning. This behaviour can be explained or with higher cognitive ability, related with the use of innovative methods, or with a generalist behaviour that offers the opportunity to use new techniques.

AbstractThe migration of city dwellers to suburbs is a commonly observed phenomenon. The growth of residential areas on the fringes of cities is referred to as suburbanisation. In the present study, migration patterns were investigated in rural districts located in the direct vicinity of the administrative boundaries of Olsztyn over a 10-year timespan. Several hundred building plot purchase/sale transactions in the form of notarial deeds were analysed to determine the dwelling place of the buyer. The analysis of the transactions revealed that the dominant group of purchasers were owners of apartments in multi-family precast concrete buildings, located in the city quarter closest to the studied suburbs. Changes in the spatial structure of suburban areas were also noted.

Land use/cover greatly affect the quality of an area. Therefore, many regional planners need assistance byother fields, such as geoinformatics, computer science, environment, and others. Although prediction and forecasting have been widely studied, in regardto real conditions (geospatial)itstill needmoredevelopment, especially thoseinvolving a combination of regional types, such as urban and suburban areas. This study uses a remote sensing base and geographic information system in predicting land in the city and district of Bekasi, West Java, Indonesia. With two scenarios compared (business as usual and vegetation conservation), the model that has been created and validated (with an AUC accuracy result of 0.828) is used to predict land use change until 2030. Scenarios with vegetation conservation are able to keep green areas to switch to land types others, such as buildings and industry

El estudio de las características urbanas y arquitectónicas, y las posibles medidas de rehabilitación para los centros comerciales de gran tamaño, fueron el punto de partida para evaluar la sostenibilidad medioambiental y urbana de los mismos. En la presente tesis, se desarrolló una metodología de evaluación de cara al análisis de las medidas de rehabilitación que pudieran aplicarse sobre un centro comercial. Se consideraron cuatro familias de medidas: Rehabilitación ecoeficiente, inserción de elementos verdes, inserción de usos en el centro, y una familia de medidas de rehabilitación aplicadas sobre el entorno urbano. Ocho casos de centros comerciales fueron analizados: tres en el contexto urbano de Sao Paulo, tres en el contexto urbano de Madrid, y tres en el contexto de la Norteamérica suburbana. El resultado del estudio permitió establecer un criterio para orientar las operaciones de rehabilitación de centros comerciales hacia ciertos ámbitos de la sostenibilidad. Las conclusiones finales del estudio fueron que es importante considerar varias medidas de rehabilitación de forma simultánea, a la vez que considerar en la escala urbana global para lograr una mejora relevante de cara a la sostenibilidad. Esto último especialmente en centros comerciales ubicados en entornos periféricos de baja densidad. Abstract. The studio of both the urban and architectural features, as well as the retrofitting means of application on a shopping mall, was the parting point to evaluate the sustainability of large surface shopping malls. A methodology to evaluate the efficacy of the retrofitting means of application on malls was developed, considering four families of retrofitting means: Eco efficient refurbishment, insertion of green elements, insertion of uses, and a family of retrofitting means applied in the urban area surrounding the mall. Eight cases were analyzed: Three located in the urban background of the city of Sao Paulo, Three located in Madrid, and two located in the background of the Suburban U.S.A. The result of this study was the establishment of criteria to focus the operations of any retrofitting program applied on a shopping mall towards some facts related to sustainability. Being the final conclusions, the affirmation that is important to consider various means of retrofitting simultaneously on the shopping mall, as well as to consider the wide urban scale to be retrofitted, in order to achieve a relevant improvement towards sustainability. Specially in cases of shopping malls located in low density suburban areas.

The paper discusses rural transformations resulting from urban influences. The analyzed area consists of rural municipalities (the smallest administrative units in Poland) in the immediate vicinity of Olsztyn, Elblag and Ełk – the largest cities in Warmia and Mazury. The type and rate of social and spatial changes in rural areas with high urban impact were analyzed. The following issues have been addressed: – a comparison between demographic changes in rural municipalities neighboring on urban centres and demographic changes in the city, – changes in the land use structure of rural municipalities neighboring on urban centers, with particular emphasis on open and protected spaces, – architectural changes in the analyzed suburban areas, – landscape changes in the analyzed suburban areas.

This concluding chapter details the aftermath of the city of Riga, as well as the changes it experienced, after falling to Russian rule. The migration of Jews to Riga, and of Russian officials and laborers, are among the many developments that would take place during the two centuries that followed Riga's capitulation to the tsar. The city's renovation and the appearance of dozens of yellow-brick factory buildings in the suburbs were still to come. The ruined city that fell to Tsar Peter I in 1710 had none of the parks, canals, gardens, and urban villas that would transform Riga into one of northeastern Europe's most attractive and welcoming cities during the twilight years of the Russian Empire. Yet, as this chapter shows, even as Riga tore down its medieval walls in the 1850s and incorporated the suburban areas, where promenades and beautiful homes were built for the city's prosperous bourgeoisie, the oldest parts of Riga would retain many of their traditional features into present times.

Air borne particulate matter PM10 and PM2.5 were collected by using Mini Vol portable Air Sampler from the world most densely populated city Dhaka and its suburban areas over a period of January through December in 2016. This study revealed a comparison of atmospheric particulate matter (PM) of a highly polluted urban area to its two neighboring areas that accommodate heavy oil based power plants. In all three sites the quantity of PM decreases in summer reaching its lowest level in the month of July, however, it increases significantly in winter season. Despite the presence of the fuel based power plants the average concentrations of PM10 and PM2.5 at the city Dhaka surpasses its two neighbors Manikganj and Nawabganj. Interestingly, PM2.5/PM10 ratio is higher at the suburban areas than urban area. The study shows that for all the sites PM2.5 is approximately twice than that of WHO and USEPA. However, the values of PM2.5 is almost similar for Nawabganj and Manikganj but much higher for the Dhaka city especially during dry season . The Mass concentration of Black Carbon (BC) was also determined from the PM samples from Manikganj and Nawabganj. Journal of Bangladesh Academy of Sciences, Vol. 43, No. 1, 59-66, 2019
