Nowadays sharing economy is strongly expanding in many areas of life. It plays a significant role in the city structure in the context of city logistics, tools like carsharing, bikesharing or scootersharing. The development of technology is conductive to the growth of this idea. The aim of the article is to present the carsharing system and its significance in the area of city logistics in the context of sharing economy on the example of Polish cities. An evaluation of this system has been carried out with regard to the positive and negative effects of development. In addition, a detailed description was made based on the carsharing system in Poland (in comparison with the solutions used across the world).

Bulqiza District is the largest chromium source, ranked fourth in the world for chrome reserves. It lays in the north-eastern part of Albania, 330-1800 m a.s.l, with 728 km² area, between 41o30’43.1N and 20o14’56.21E. There are 136 entities with chromium extraction activity and around the city of Bulqiza (2.6 km² and 13000 inhabitants), there are 33 entities. The aim of the study was the identification of the environmental state and environmental impact assessment of chromium extraction (chromite mining) and giving recommendations to minimize the negative effects of this activity. Field observations, questionnaires, chemical analysis of soil and water, meetings and interviews with central and local institutions as well as with residents were used for the realization of the study. The obtained results showed that chromium extraction causes numerous irreversible degradation of the environment in the Bulqiza area, such as the destruction of surface land layers and erosion, destruction of flora and fauna, soil and water pollution, health problems, unsustainable use and reduction of chromium reserves, etc. The inert waste that emerges after the chromium partition is discharged to the earth surface without any regularity, covering the surface of the soil and flora, leading to irreversible degradation of the environment. Most of the mining entities do not respect the contracts and environmental permit issued by the Ministry of Energy and Industry (MEI).

The Conversions of the City Structure and their Influence on the Demographic Phenomena The process of socio-economic change, which started in Poland in 1989, began the series of modifications in the structure of Polish cities. These changes embrace the economic sphere and the social sphere, as well as the habitable environment. The changes occurring in Polish cities resemble the processes present in settlement systems in highly developed countries. They take place, however, with some delay which is caused by the movement from the centrally controlled economy to the market economy and all the problems associated with it.The aim of the presented article is to show the influence of occurring changes on the socio-economic development and demographic situation apparent in small towns of the Wrocław Metropolitan Area (WrMA). The attempt of evaluation of factors promoting the development was undertaken. The value of chosen characteristics was analyzed for the set of small towns of Dolnośląskie voivodship. The analysis of chosen quantities common for demographic phenomena in a longer time cross-section (1995-2008) pinpoints the irregularity of development of specific towns, which may result in negative effects for the whole area in the future.

In the article the relevance of this research is due to overcoming the complex of social, environmental and economic problems in urban planning related to environmental improvement, improvement, greening of cities and settlements. Being one of the main elements of urban planning, "green spaces" form a favorable ecological environment. They also help to combat the effect of "thermal islands" by participating in the process of evaporation of moisture; reduce storm water runoff; improve air quality by absorbing atmospheric pollution. Improvement of cities is one of the priority tasks of forming a comfortable urban environment. It includes: improvement of the ecological situation in cities (related to the improvement of the landscaping system, which means scientifically grounded spatial arrangement of all components of urban landscaping according to urban areas) soil, climatic and other factors in order to achieve optimal ecological, sanitary and sanitary and sanitary effects. In the foreign practice of urban planning use the concept of "green infrastructure" ("Green infrastructure") or blue-green infrastructure ("Blue - green infrastructure"), which focuses on the environmental importance of the territory. Which considers the whole spectrum of landscape changes and serves as a basis for the formation and development of a favorable state in cities. The main reason for the interest in green infrastructure in the world is the desire to make the city a more conducive place to live, as well as to climate change. Reducing the negative impact on the environment is the key to the socio-economic development of the country. The purpose of this work is to develop recommendations for the design of green infrastructure. Analysis of existing experience in designing and implementing green infrastructure in an urbanized environment, identifying trends in the further development of their architectural and urban planning structure. The object of the study is the green infrastructure of major cities in the world, including its architectural and urban planning and spatial solutions in the city structure. The article presents typical landscaping schemes and their classification, as well as methods of using green spaces to improve the environmental, social and aesthetic status of cities.

AbstractCity logistics has the goal of optimizing the entire logistics system within the city area and thus positively impact the quality of life. Different measures and initiatives, aimed at the optimisation of city logistics and reduction of the negative effects of urban freight transport are access zones or goods (freight) receiving points in the city centre, restrictions of vehicle dimensions, time schedule of delivery, consolidation strategies, use of urban distribution or consolidation centres, use of electric cars, use of urban public transport and mobility management. In the last couple of years, the city of Šibenik has experienced a tourism boom, which includes the organisation of numerous festivals in the old town core, an increase in the number of visitors, an increase in the number of catering and shopping facilities, private accommodation units, hotels and hostels. The increased number of tourists and commercial establishments also broaches the question of delivery of food and non-food products into the old part of the city, especially during the tourist season.

Understanding future expectations and fulfilling current demands with a view of conserving social, cultural and natural environment of a destination, can be referred to as sustainable  tourism.  Changes  in  social  and  cultural environment are identified a little early than their natural counterpart. The first two being more vocal and narrates quick reactions among its audiences. Changes in natural environment lie silent till the time they reach a visible level  of  depletion.  The  present  paper  will  highlight sustainability issues in river tourism, which is one of the significant natural resources for tourism. Understanding the dependency of tourism on rivers and highlighting its positive and negative effects of it, will be discussed in the paper. The paper is supported by a case study on „The Ganges in Varanasi‟.  The Holy Ganges is the lifeline of the city and is facing immense sustainability issues, which has  raised  questions  against  her  future  existence.  The problems  faced and  measures  taken by  various organizations,  government  bodies,  and  individuals  to protect the lifeline of the oldest living city of the world will be examined further.

Recently, urbanism interventions have caused major changes in the spatial and physical structure of Iran cities. These interventions have changed primary spatial organization pattern and the city′s main structure. In the process of this physical development in many historical cities, it has not been enough attention to the structure and historic core shape of the city and subsequently, problems such as the inability to adapt to the new physical changes, the lack of appropriate linkage with the available network structure and its diminution in the minds of people, have aggravated the historical cores. Recognition of the main cities structure and skeleton based on analysis of all components of cities is difficult and impossible. Space organization theory (space syntax) is one of the methods that has responded to the needs of cities’ spatial analysis.This research, with the aim of investigating the impact of urban development plans on the spatial structure of the historical boundaries of Urmia investigating and analyzing the city structure in four important periods (2016-1996-1974-1930), using space organization method. Results of this study, demonstrated that was decreased functionality and coherence of the historical area and its relation to the totality of city structure affected by physical changes over time. And the inner structure of this area could not be linked to the city's overall structure. Also, a large part of the identity and physical values of texture are demolished by discontinuity of the main elements of the area. The functional importance of historical orders has been weakened and this means that rapid physical changes, had negative effects on the spatial structure of historical area.

The paper herein presents greenp-median problem (GMP) which uses the adaptive type-2 neural network for the processing of environmental and sociological parameters including costs of logistics operators and demonstrates the influence of these parameters on planning the location for the city logistics terminal (CLT) within the discrete network. CLT shows direct effects on increment of traffic volume especially in urban areas, which further results in negative environmental effects such as air pollution and noise as well as increased number of urban populations suffering from bronchitis, asthma, and similar respiratory infections. By applying the greenp-median model (GMM), negative effects on environment and health in urban areas caused by delivery vehicles may be reduced to minimum. This model creates real possibilities for making the proper investment decisions so as profitable investments may be realized in the field of transport infrastructure. The paper herein also includes testing of GMM in real conditions on four CLT locations in Belgrade City zone.

With the technological advancement of ICT, the cities of the world are becoming so dependent that ICT is challenging the conventional ideas and classic theories of city structure. The cities of the world are undergoing a transition that is caused by the shift of principle from ‘physical movement’ to ‘virtual movement’. The state-of-the-art ICT featured by internet and e-commerce (Business-to-Commerce - B2C) is facilitating such shift which influences in changing the conventional ideas and structure of CBD, core business areas, city center, etc. Though the magnitude of influence on the transition process is yet to be known, there is an obvious transition that almost all cities of the world are experiencing. This book chapter conceptually discusses and portrays the potential changes in the conventional city structure by analyzing three classic city models (i.e., multi-nuclei, concentric and sector models), exploring the technological advancement in ICT and increasing dependencies on it and by drawing evidence from a pilot case study. This chapter argues that ICT induced change in the city structure, which we may call ‘future city’ or ‘transitional city’, would bring positive impacts on the physical and social environment, competitive land and transportation system in the city.

The sharing economy has gained much attention recently as Airbnb and Uber are spreading across the world, but little is known about how to unlock the true potential of the sharing economy. As such, this study aims to unearth the barriers and challenges associated with the sharing economy platform environment in the city of Umeå, Sweden. The qualitative case study focuses on sharing economy efforts in the city of Umeå, a city characterized by high technical competency and world leading broadband connectivity, while having almost no activity in the digital sharing economy. The study identifies the barriers, pathways, and opportunities related to the sharing economy and how they apply to the city of Umeå. As such the study reveals the ways in which the sharing economy can help a city increase their digital density as well as making the city more attractive for those living in and traveling through the area.
