The aim of the paper is to draw attention to risks and challenges faced by the national grid infrastructure both in the area of transmission and distribution. The study presents the characteristics of the network grid in the area of transmission and distribution. The threats concerning the transmission and distribution infrastructure were also discussed. Both the national transmission and the distribution grids are adapted to presently occurring typical conditions of the demand on electricity and to the execution of internal tasks in normal states, but they may pose a potential threat to the security of the energy supplies. In the context of the forecasted future growth of the electricity demand, the insufficient capacity of the National Power System in domestic sources and sources available through interconnections, the uneven distribution of sources and customers with the lack of adequate grid transmission capacity, the necessity to improve the quality and reliability of energy supply to end users and to intensively develop renewable energy sources, the current grid infrastructure in the area of transmission and distribution will be insufficient. It will be necessary to expand and modernize the 400 and 220 kV transmission grid, the 110 kV distribution grid, in large urban agglomerations in particular, the MV distribution grid in rural areas in particular, and to implement investments aimed at increasing the export and import capacities of the National Power System. The paper presents challenges faced by transmission and distribution system operators. They mainly concern the field of investments and the area related to the preparation and implementation of investments in the grid. These challenges result from national legislation which is inappropriate and imposes many legal and administrative barriers substantially limiting the speed and effectiveness of the investment process.
With the increase in the mass of municipal waste generated, the demand for facilities dealing with their development is increasing. The aim of the research was to determine environmental and anthropogenic factors affecting the location of waste management facilities and an attempt to indicate potential locations for selected waste management facilities in the communes of the Sądecko-Gorlicki region. The scope of work included: a review of existing waste management facilities in the studied region, acquisition of geodatabase for digital data, analysis of the distance between the waste management facilities and environmental or anthropogenic elements, and analysis of potential locations designated in the GIS based on the developed criteria.As a result of spatial analyzes, it was found that in the study area, there are 3 places of potentiallocations for installation of municipal solid waste treatment facilities.
The activity of territorial self-government shaped institutionally during the development process is characterized by a significant scope of care for the financial situation, which determines the efficiency of its functioning. The general availability of public services is a condition for the assessment of the activities of municipalities (powiats, voivodeships). Institutional economy as a real one, takes into account an integrated point of view. The aim of the study is to present the territorial differentiation of the eff ectiveness of communes’ activities in the context of institutional economics and to present the possibility of using a synthetic measure in this process. The synthetic measure of development fluctuated within the limits of 0.30 – Wąchock (Starachowice poviat, urban-rural commune) to 0.41 – Ostrowiec Św. (Ostrowiecki poviat, urban commune) in 2009, 0.32 – Łączna (Skarżysko poviat, rural commune) to 0.40 – Starachowice (Starachowice poviat, municipal commune) in 2015. The results of the analysis confirm the existence of small differences in the assessment of development communes of the Kamienna Basin. This approach allows the assessment of municipalities using one size and allows you to organize the analyzed objects in terms of the considered phenomenon.
On May 7, 2010 the act dated March 4, 2010 on the spatial information infrastructure was published which transposes the European Parliament and the European Council Directive No 2007/2/WE dated March 14, 2007 established the spatial information infrastructure (INSPIRE) in the European Community. This act introduced basic changes to the binding Act, i.e. the Law of Geodesy and Cartography and, as the consequence, the demand to develop various administrative decrees occurred. The authors of the paper present the analysis of the existing conditions of the cadastre, the task of governmental and public government administration, related to demands concerning the cadastral reforms, following the act on the spatial information infrastructure and they discuss possibilities to perform such reforms at the local and national scales.
Polish energy security is currently one of the key elements affecting the national security system. Maintaining operational efficiency and the permanent modernization of both, power plants, as well as transformer stations and transmission networks is a starting point of ensuring energy security in our country. This is a significant challenge, taking into account the age of the energy critical infrastructure elements in Poland, as well as the permanent increase of the demand for electricity. This implies a systematic growth of the importance of the issue the country’s energy security. The numerous events and anomalies that accompany our everyday life, such as the storms that passed over Poland on the night of August 11–12, 2017, indicate the considerable sensitivity of the critical energy infrastructure on the impact of various negative factors. The security of Polish critical infrastructure connected with the distribution of electricity is particularly at risk. Therefore, it is desirable not only for current repairs and the modernization of the power system elements, but also for the work related to adapting the infrastructure to current and even forecasted needs, challenges and threats. In the face of the presented research results, the reconstruction of the Polish power system, as well as the implementation of innovative solutions in the production, transmission and distribution of energy seems to be unavoidable. Therefore interdisciplinary research and analyses are recommended, allowing the level security of the critical infrastructure to be increased through the best possible diagnosis of factors that may even slightly threaten this security.
One of the important issues concerning development of spatial data infrastructures (SDIs) is the carrying out of economic and financial analysis. It is essential to determine expenses and also assess effects resulting from the development and use of infrastructures. Costs and benefits assessment could be associated with assessment of the infrastructure effectiveness and efficiency as well as the infrastructure value, understood as the infrastructure impact on economic aspects of an organisational performance, both of an organisation which realises an SDI project and all users of the infrastructure. The aim of this paper is an overview of various assessment methods of investment as well as an analysis of different types of costs and benefits used for information technology (IT) projects. Based on the literature, the analysis of the examples of the use of these methods in the area of spatial data infrastructures is also presented. Furthermore, the issues of SDI projects and investments are outlined. The results of the analysis indicate usefulness of the financial methods from different fields of management in the area of SDI building, development and use. The author proposes, in addition to the financial methods, the adaptation of the various techniques used for IT investments and their development, taking into consideration the SDI specificity for the purpose of assessment of different types of costs and benefits and integration of financial aspects with non- financial ones. Among the challenges are identification and quantification of costs and benefits, as well as establishing measures which would fit the characteristics of the SDI project and artefacts resulting from the project realisation. Moreover, aspects of subjectivity and variability in time should be taken into account as the consequences of definite goals and policies as well as business context of organisation undertaking the project or using its artefacts and also investors.
The wide access to source data, published by numerous websites, results in situation, when information acquisition is not a problem any more. The real problem is how to transform information in the useful knowledge . Cartographic method of research, dealing with spatial data, has been serving this purpose for many years. Nowadays, it allows conducting analyses at the high complexity level, thanks to the intense development in IT technologies, The vast majority of analytic methods utilizing the so-called data mining and data enrichment techniques, however, concerns non-spatial data. According to the Authors, utilizing those techniques in spatial data analysis (including analysis based on statistical data with spatial reference), would allow the evolution of the Spatial Information Infrastructure (SII) into the Spatial Knowledge Infrastructure (SKI). The SKI development would benefit from the existence of statistical geoportal. Its proposed functionality, consisting of data analysis as well as visualization, is outlined in the article. The examples of geostatistical analyses (ANOVA and the regression model considering the spatial neighborhood), possible to implement in such portal and allowing to produce the “cartographic added value”, are also presented here
Circular economy – a new approach in the understanding of the human–environment relationship. The work presented the assumptions of the circular economy as a new concept of the economy functioning with the method of production “from cradle to cradle” constituting the opposition to the commonly used linear economy approach (take, make, dispose). Work discussed also the impact on the quality of human life and the management of environmental resources. Functional assumptions of the circular economy and its territorial dimension were presented, especially in urban areas where the green economy and sharing economy mechanisms are used. The potential for economic growth and the creation of new jobs was also emphasized due to the implementation of circular economy in the EU countries.
Expenditures Related to Technical Infrastructure. The aim of the study is to answer to the question what is the economic (financial) scale of expenditure and local investments related to the technical infrastructure and to what extent the investment processes are correlated with the planning coverage. The study is based on data used in the annual reports of the Institute of Geography and Spatial Organization of the Polish Academy of Sciences on the state of planning work in communes. A detailed analysis of municipal budget expenditures was carried out, demonstrating large diversity of water and sewerage services, road construction and renovation, investment expenditures, etc. The research showed that a significant part of the investment is located outside local plans based on the decision on building conditions. This creates a serious risk of irrationality of spatial management and leads to increase of infrastructure service costs.
The cadastral data, including land parcels, are the basic reference data for presenting various objects collected in spatial databases. Easy access to up-to-date records is a very important matter for the individuals and institutions using spatial data infrastructure. The primary objective of the study was to check the current accessibility of cadastral data as well as to verify how current and complete they are. The author started researching this topic in 2007, i.e. from the moment the Team for National Spatial Data Infrastructure developed documentation concerning the standard of publishing cadastral data with the use of the WMS. Since ten years, the author was monitoring the status of cadastral data publishing in various districts as well as participated in data publishing in many districts. In 2017, when only half of the districts published WMS services from cadastral data, the questions arise: why is it so and how to change this unfavourable status? As a result of the tests performed, it was found that the status of publishing cadastral data is still far from perfect. The quality of the offered web services varies and, unfortunately, many services offer poor performance; moreover, there are plenty services that do not operate at all.
