Poland is now faced with the task of developing a long-term energy policy for decades to come, a strategy capable of reconciling the security of power supplies as well as effective economic processes, ensuring adequate standards of environmental protection. The process in which fossil fuels are converted into energy carriers of choice is accompanied by the emission of various gas substances which escape into the environment. Later on, those substances accumulate in the atmosphere as greenhouse gases affecting the Earth’s radiation balance – the greenhouse effect. Upsetting the balance between emission levels of those gases and the capacity to convert them in the atmosphere is the reason for climate changes. Sustainable development indices constitute a monitoring tool which makes it possible to create a statistical image of a country from the perspective of a new development paradigm. The most important feature of this index is the capability of comparing values, enabling to determine the position of a given object with reference to other objects. The article analyses 8 indexes of sustainable development in terms of using biomass for power generation purposes. The analysis was performed to include three social order indices, two economic indices and one environmental order index. It was concluded that the use of biomass in power generation can reduce the emission of greenhouse gasses significantly at several stages: the emission can be eliminated from the biological process of biomass conversion, storage and it can also be reduced during transportation.
One of the current challenges in transport is e-mobility, understood as electromobility, ecomobility and mobility economics. E-mobility is nowadays a key focus area of socio-technical change, in terms of attention from policy makers as well as from industry and the public. The societal challenges ahead, in particular climate change put increasing pressure on the current mobility system, due to its tremendous environmental impact. Furthermore e-mobility is seen as major economic opportunity for the automotive industry. In this context, based on the available literature and documents and practical solutions implemented already in cities and agglomerations, the paper discusses the fundamental challenges that cities are to face in the context of the current megatrends. This process will engage diff erent stakeholders in order to make this concept become a reality.
It is contended that, in essence, climate policy is sustainable development policy, given that it postulates the use of renewable resources, and an increase in the effectiveness of use of non-renewable ones. Furthermore, it serves the security of future generations more than present ones; for while unfavourable impacts of climate change are already making their presence felt, truly negative consequences of considerable signifi cance are likely to be more of a matter for the second half of the present century. This is why, in analysing the evolution of the approach to climate policy through the late 20th century and into the 21st, it is also possible to appraise changes in the approach to the sustainable-development concept. This article has therefore sought to offer the author’s analysis of how the approach to sustainable development has evolved, by reference to Poland’s climate policy from 1988 through to 2016. As this is done, an attempt is also made to identify the conditioning that has decided upon and will go on determining the shape of national policy in this domain. Climate policy in Poland has been developing since the early 1990s. At the outset, it was not a source of controversy, with the consequence that the country rather rapidly signed up to and then ratifi ed the Kyoto Protocol to the UN Framework Convention on Climate Change. However, as early as in the late 1990s, reservations began to be expressed, to the effect that actions to protect the climate might pose a threat to Poland’s economy. A key turning point as regards the approach came with the growing dispute over the EU 2020 Climate and Energy Package. It was also at this time that a thesis began to take shape, holding that the goals of climate policy where at best unfavourable and at worst dangerous for Poland. This approach in fact held sway in successive years, leaving this country’s cooperation with the EU over this matter severely hindered. The main reason for this change of approach to climate policy can be considered to lie in the politicisation thereof, and hence the increasing dominance of the short-term interests of the Polish political elite over either the public interest or the security of future generations.
In 1981, Polish canoeists (members of the Bystrze Academic Travel Club) made the first journey along the waters of the River Colca in the section located in Arequipa Province (Peru), along which the waters flow in a deep canyon. Information on this sporting achievement – and a description of the Canyon and its surrounding area filled the Peruvian press and tourist publications around the world, ensuring that the Colca Canyon became one of the most important goals for tourists anywhere in Peru from that time on. However, mass infl uxes of tourists, noisy trips, the development of hotel infrastructure and other items required in tourism have generated permanent change in the character of the Colca Valley, and done much to influence the lives of its inhabitants.
The development of both the town and the administrative commune of Zielona Góra is characterised by a progressive process of uncontrolled linear urban development, so called urban sprawl. This phenomenon has existed in the town for a long time, but because of the fast development in the 21st century it is now even stronger and has an unfavourable impact on the dwellers’ comfort, communication and accessibility. The directions of changes adopted for spatial development in the current strategic documents of the new town (since 1 January 2015), which came into being as a result of the merger between the town and the rural commune of Zielona Góra, do not guarantee that the unfavourable processes will be stopped. The process of uncontrolled urban development results in the growth of dense urban structures along the roads and communication routes. This prevents an optimum use of areas located further away or behind the existing infrastructure and causes dead zones to appear, where there are no communications or infrastructure. With each new investment (a plot of land with access to a public road, as specified by the regulations) the distance between recreational areas (green spaces) and the town centre increases. The deteriorating dwelling conditions are a direct result of the unfavourable phenomenon of urban sprawl.
The social, economic and environmental zone is constantly changing in terms of factors aimed at improving the quality of life, economic and technological development of the city while at the same time rational use of resources of the natural environment. Change as a dynamic factor is an impulse for creating new behaviors of residents and interactions between them and public and private sector entities. The article attempts to systematize selected contemporary concepts shaping the city, emphasizing the coherence of their assumptions and the scope of the issues discussed. Looking for features that characterize the city, which balance the needs and expectations of its users.
The article aims at determining the place and role of environmental issues in spatial management in relation to scientific achievements of Professor Zbyszko Chojnicki. A few words about the professor’s approach to the issue of using the natural environment in spatial management provide a starting point for the ongoing discussion. Next, attention is paid to the place of environmental issues in the interactive model and in the conception of the territorial social system by Professor Chojnicki. This concerns first of all the distinction and description of these elements of the natural environment and environmental relations which are identified in these systemic aspects. In the following part of the article, the analysis of environmental issues is carried out as the subject of interest of spatial management in the context of scientific achievements of Professor Chojnicki in this field. The paper concludes with a short presentation of studies inspired by works of Professor Chojnicki on sustainable development of cities.
Regeneration – an integrated process of activities undertaken in the spatial, social and economic dimensions – should lead to the improvement of the living conditions of inhabitants of degraded urban areas. The European Union in 2007- 2013 allocated financial resources for this purpose in the form of JESSICA initiative which is based on financial engineering mechanism. Experiences gained so far allow conclusions to be drawn that JESSICA is a highly fi nancially-effi cient instrument but, however, not always delivers the desired outcomes in the spatial and social sphere. The scope of projects often is limited to infrastructural investments and does not reflect the complexity of regeneration process. In the article the authors analyse experiences of the five Polish regions with the use of JESSICA, point out main problems and formulate recommendations for sustainable urban policy.
Housing Stock and Its Public Dimension in the Role of Infrastructure of Durable Development. Only the reciprocal composition and location of buildings and their inhabitants in relation to the location of settlement infrastructure and other spatial development components can give housing stock a public dimension. The importance of the public impact of the housing stock on civilization development results mainly from the multifaceted role of the standards of its settlement in the shaping of inhabited space. Appreciating this impact can help build a necessary community of people living in common social and settlement structures. The importance of housing policy in balancing the development of living space is highlighted by the current structural crisis of the capitalist economy. The underestimated field of overcoming this crisis is the public dimension of housing stock. The presented reasoning subordinated to such thinking is part of a wider narrative combining architectural, urban, planning and sociological issues.
Ecological Awareness and Social Capital and Implementation of Sustainable Development. The importance of social commitment to sustainable development and the need of forming of the homo cooperativus attitude are underlined in the principles of sustainable economics. Environmental awareness and social capital are two key factors that influence the implementation of sustainable development. The main aim of the article is to analyze of both concepts definitions and to indicate the relationship between them. It also classifies social attitudes resulting from the level of social capital and ecological awareness.
This article takes up the matter of contemporary threats to cities and urbanity, setting the problems cities face today against the background of the two categories of the resilient city and the city developing sustainably. The author describes and presents the evolution of the sustainable development concept as such, as well as the generational change in priorities that has taken place where the development of urbanised areas is concerned, given the way the concept has undergone a certain devaluation, in the light of its failure to achieve fulfi lment. The challenges cities face today require multi-faceted activity, in respect of increased inclusivity, robustness and resilience, and flexibility. This leaves today’s idea of the resilient city embracing old elements of the sustainable city, but also augmenting them in various ways.
The aim of this paper is to discuss energy certification systems and multi-criteria certification schemes – both the assessment tools focusing on the level of the single building and on the urban level. The role of certification systems and the emerging technologies as a means of reducing energy consumption and achieving the high energy quality of the built environment is investigated.
The paper presents an analysis of the sustainable development of electricity generation sources in the National Power System (NPS). The criteria to be met by sustainable power systems were determined. The paper delineates the power balance of centrally dispatched power generation units (CDPGU), which is required for the secure work of the NPS until 2035. 19 prospective electricity generation technologies were defined. They were divided into the following three groups: system power plants, large and medium combined heat and power (CHP) plants, as well as small power plants and CHP plants (distributed sources). The quantities to characterize the energy effectiveness and CO2 emission of the energy generation technologies analyzed were determined. The unit electricity generation costs, discounted for 2018, including the costs of CO2 emission allowance, were determined for the particular technologies. The roadmap of the sustainable development of the generation sources in the NPS between 2020 and 2035 was proposed. The results of the calculations and analyses were presented in tables and figure
During studying and mathematical description of the trends of urbanized territories development as ecological and town-planning systems there were several vague similarities founded between its major parameters change periodicity and other physical values, having undulatory nature. Obtained counterparts had predetermined interest for search of fundamental basics of urbanization. It turned out that all laws of Nature has the same basis – power permanence rule. This law is known in philosophy as principle of «change of unchangeable», in ecology – as a law of ecosystem self-regulation, in accordance to which at conditions of insufficient occupancy of the territory the population amount growths, and at conditions of over-occupancy it decreases. According to research, also development attributable to the dynamics of urbanized territories is noticeable, in which all the four types of physical interactions are expressed to a certain degree. These and other results of research have allowed to articulate the main principles of ecological space «urban physics» content, which have proven to be coordinated with the postulates of new single field physics (Bishkek version). The above-mentioned have allowed to lay down the theoretical foundation for an occurrence of a new branch in the science of townplanning i.e. wave urbanistics, as a science of management by unduly processes of territories development in order to provide a conditions of their sustainable development.
The paper presents the concept of vital cities in the context of mechanisms of sustainable development, networking and creativity. The vital city was presented as: - a city belonging to the inhabitants – a city managed and developed with advanced processes of participation, - a city of reasonable management – a city that uses and at the same time protects its key potentials, - a city of creation – a city of creating and implementing new ideas, - a city of opportunities – a city that creates the conditions for the use of energy and creativity residents, - a city in the surround – a city with a strong position in the environment.
This paper presents the use of multi-criteria analysis as a tool that helps choosing an adequate technology for a household wastewater treatment plant. In the process of selection the criteria of sustainable development were taken into account. Five municipal mechanical-biological treatment plants were chosen for the comparative multi-criteria analysis. Different treatment technologies, such as sand filter, activated sludge, trickling filter, a hybrid system - activated sludge/trickling filter and a hybrid constructed wetland system VF-HF type (vertical and horizontal fl ow) were taken into account. The plants’ capacities were 1 m3∙d-1 (PE=8) and they all meet the environmental regulations. Additionally, a solution with a drainage system was included into the analysis. On the basis of multi-criteria analysis it was found that the preferred wastewater treatment technologies, consistent with the principles of sustainable development, were a sand filter and a hybrid constructed wetland type VF-HF. A drainage system was chosen as the best solution due to the economic criteria, however, taking into consideration the primary (ecological) criterion, employment of such systems on a larger scale disagree with the principles of sustainable development. It was found that activated sludge is the least favourable technology. The analysis showed that this technology is not compatible with the principles of sustainable development, due to a lack of proper technological stability and low reliability.
The sustainable development of human activities is directly related to the protection of the environment by lowering the anthropogenic stress. Pharmaceuticals – due to their growing consumption (use in medicine, veterinary, animal production, cosmetics) and their incomplete removal in wastewater treatment plants – are classiﬁed as a group of new and rapidly emerging pollutants which have been proven to have a negative impact onto water organisms. In order to ensure the proper protection of human health and the environment there is an urgent necessity of determining pharmaceuticals in clinical, cosmetic, food and environmental samples. Gas (GC) and high performance liquid chromatography (HPLC) are valuable techniques for such determination, especially when they are coupled with mass spectrometry (GC-MS; LC-MS) or tandem mass spectrometry (GC-MS/MS; LC-MS/MS). The purpose of this paper is to present an analysis of sustainability features of analytical techniques in the light of necessity to determine trace amounts of pharmaceuticals in the aforementioned different matrices. Using the Delphi method we performed an analysis of the key sources of the competitive advantages of the application of GC and GC-MS techniques for determining the pharmaceutical residue in clinical, cosmetic, food and environmental samples – compared to techniques based on HPLC or LC-MS. The analysis covered the following areas: (i) the features of the technique, (ii) the price, and (iii) the applicability in various sectors of economy.
The article aims to present the scope of influence of Integrated Territorial Investments (ITI) on the sustainable development of urban functional areas (FUAs) in Poland. Against the background of the general principles of the implementation of the both instruments, practical aspects of the implementation of ITI in FUAs have been presented. Detailed analyses in the financial and spatial aspect were carried out using the Sustainable Development Indicators (SDI). These provided the basis for presenting the practical aspect of supporting the sustainable development of urban functional areas in the EU Cohesion Policy 2014–2020.
Axiological chaos and unsustainable man’s acting in a contemporary world has led him to a total confusion. He constantly acts toward environmental and cultural degradation. Also in social dimension a permanent and “general” crisis dominates. The crisis is rooted on multi-category stratification and based on post-truth models of interpersonal communication in traditional and virtual realities. Neoliberal model of economical conquest, in turn, effects unsustainability in economic sphere. Thus, in common reception – for the most people in the world – such situation has become unbearable. So, it is the educators’ duty to look for – with the intention to put into practise – such concepts and pedagogies, which could prepare the whole global society to real – not declaratory false – co-creation of its life in the world, understood as an actual and common home. Taking such perspective, the theory of Argentinian philosopher – Ernesto Laclau becomes an interesting proposition. The time of mono-dimensional – protestant and neoliberal – interpretation of values comes to the end. Now the time has come to accept the equality of different – having their roots in various cultures – value understanding. Possibility of local and particular interpretation of values – along with maintaining the rule of common good – gives the chance to update the education according to real, thus multidimensional humanistic ideal. Such a standpoint presents a way to cure/reform intercultural education, which nowadays is at an impasse. Mainly it uses stiff schemes and repeated patterns, so it has become imitative and conservative. In its contemporary formula intercultural education is not able to respond to present challenges of multicultural and global society. The need to implant into its structure the concept of sustainable development emerges as a must.
