The article presents an overview of selected approaches to the functioning of the natural environment in the city, particularly in the areas of urban greenery , in the context of its utility and value to humans. Starting from the concepts of ecological functions and the potential of natural environment, it indicates the significance of the concept of ecosystem services and the possibilities for its application. The author presents the latter approach as the most comprehensive and taking into account the economic value of natural resources. Some practical conclusions related to the possible applications of the ecosystem services concept in managing the sustainable development of the city are also presented.
The paper introduces the topic of geo-information services, which serve to publish spatial data on the Internet. In particular it is focused on two types of services that will serve as reference standards for developing data download services within the Infrastructure for Spatial Information In Europe (INSPIRE). These two standards are: Web Feature Service (WFS) and Web Coverage Service (WCS). Their implementations are still much less popular than Web Map Service (WMS) implementations for viewing map data. However, in this paper, the growing prospects for the development of WFS and WCS services are indicated, as well as their specifications and current leading implementations are described. In the Polish web resources it is worth to notice the implementations of WFS on the governmental portal - Geoportal.gov.pl. Another good example - from a local government unit - are WFS services on the web portalof the Spatial Information System of Wrocław. Implementations of WCS are still not present in the Polish web resources, despite their growing popularity in the World. In the paper the very essential topic of legal conditions for the use of spatial data downloaded by the means of geo-information services is also outlined (i.a. the issues of: intellectual property rights, data pricing, data sharing for the purpose of the execution of public tasks). In the conclusion the attention is paid to the assets of geographic information systems (GIS) and geo-information services (in particular: data download services - WFS and WCS) for their application in spatial management and urban planning.
The purpose of the study was to evaluate the relationship between the implementation of the local spatial policy, the conditions arising from the location of motorway junctions and the development of built-up areas. Taking a sample of three municipalities located in the vicinity of the A2 motorway junctions (interchanges), factors have been identified associated with the influence of spatial planning on the proliferation of residential development. With this aim, statistical data, local planning and strategic documents, as well as information obtained directly from the local authorities, have been analysed. The conclusion is that local governments implement spatial policy and investment policy in a heterogeneous way, which affects significantly not only the local economy, but may also have influence on the settlement development. The potential arising from the location of a motorway junction is a growth factor to be taken under consideration, but equally important, or even more relevant role to play has the position relative to urban centres.
Motorway junctions are special places that, due to the crossing of transportation corridors, concentrate in their surroundings potential investment areas and may stimulate local development. The study identified key determinants of local demography related to the age structure, population growth and net migration rate, for selected communes located in the vicinity of the A2 motorway junctions between Łódź and Poznań. It also examined whether the changes in the local demographic structure may be following the development of investments. As a result, it was found that the demographic situation of communes varies depending on the type of municipality, size of settlements, location with respect to the motorway junction, location relative to major cities, as well as the development policy pursued by the local authorities.
Geoportals are complex web services offering access to the spatial data by the means of various types of services for metadata discovery, map viewing, data download. National geoportals in many countries are serving as central nodes of national spatial information infrastructures. In the European Union the establishment of national geoportals is a part of the process of implementation of the INSPIRE Directive, which regulates the rules for establishment of these infrastructures. Geoportal.gov.pl, a service managed by the Head Office of Geodesy and Cartography (GUGiK), fulfills this role in Poland. The Geoportal offers access to various layers of information useful for spatial planning purposes. It is a relatively new source of information for urban planners and other groups of users (launched in 2008). The service shall enable gathering information related to the current topography, land use or land partition, performing multi-directional analyses based on various reference and thematic data layers. Sporadic technical problems with the functioning of the service or lacks in coverage of the whole country area for some data layers (EGiB - the cadastre, TBD - the topographic database) and problems with up-to-dateness of the data in relation to the existing users' needs (e.g. in case of ortophotomaps), do not dampen the high functionality and usefulness of the Geoportal. Certainly, the full extent of the analytical capabilities of the "desktop GIS" software (specialized GIS software, installed on the user's computer) is not available in this case. More vital is the legal issue concerning the opportunities for the use of data downloaded from theservice for commercial and non-commercial purposes (permissions, fees) and for the purposes of execution of public tasks. Recently (June 2012) a test (beta) version of the new service "Geoportal 2" has been launched. The new service is intended to have much extended functionality. The projects currently executed by GUGiK are a part of the national informatization policy and the process of establishing of electronic administration (e-administration) in Poland, also aiming to bound the national spatial information infrastructure with the European network, in the framework of the implementation of the INSPIRE Directive.
Interview with Prof. Amnon Frenkel was carried out in June 2013 in Technion - Israel Institute of Technology at the Faculty of Architecture and Urban Planning. The Professor is leading the programme of studies in the field of urban and regional planning in the oldest and most prestigious technical university in Israel. Professor Frenkel is the co-author of the book "Technion Nation", which shows the great influence of the Technion Institute and graduates on the modern state of Israel.
The article is an overview of the results of an annual survey on the status and conditions of spatial planning works in Polish communes realized in the Institute of Geography and Spatial Organization of the Polish Academy of Sciences, in its part concerning the financial consequences of the adoption of local spatial development plans. Data representing the situation at the end of 2014 in the range of projected and realized expenditures and incomes of local budgets was collected by the Central Statistical Office of Poland from questionnaires filled out by employees of communes. The data was analyzed according to administrative categories of communes, as well as divided by provinces (voivodships). The survey revealed several regularities: a high share of expenditures and revenues related to the implementation of zoning plans in the budgets of local government units; concentration of the highest financial turnovers in a relatively small part of the municipalities; negative financial balance of adoption of the majority of spatial plans. What attracts attention is also a large heterogeneity of financial and spatial policies conducted by communes.
The paper concerns the access to the public information regarding local spatial planning in Poland. Particular attention is given to the spatial information disseminated on the Internet in compliance with the guidelines of the INSPIRE Directive of the European Parliament and Council. The study area of the project was Opolskie Voivodeship in southern Poland. An analysis was executed of the availability of local spatial planning acts, including their graphical parts, on the municipal websites and in the Bulletin of Public Information (BIP). The analysis included completeness of these documents and their available data formats. Moreover, websites of the municipalities / communes (Polish: gminy) were checked for availability of interactive maps or geoportals serving spatial data, especially regarding land use and spatial planning data from local spatial planning documents. The research revealed that the availability of the documents on the Web is currently broad, however not all graphical attachments are included and some, especially older, but still binding, documents are not available at all, despite the legal obligation. On the other hand, the availability of the spatial data regarding spatial planning (related to the INSPIRE "Land use" data theme) via local geoportals is very low. Even in the case of communes having their own geoportals, the spatial planning information is rarely presented and network services for spatial data dissemination (WMS, WFS) are not available. The study area was only one region (voivodship) however a general conclusion can be extrapolated that Polish communes are currently not prepared for the implementation of the INSPIRE Directive guidelines within the scope of the "Land Use" data theme.
The aim of the article is to discuss the issues related to the existing legal and planning conditions of the location of wind turbines in Poland and in selected countries of the European Union. The basic question concerns the differences in approaches to regulations indicating areas that can be used for investments in the branch of the energy sector. In particular, it was examined whether the current legislation in Poland, including spatial planning, concerning the location of wind farms is in line with the standards applied in other European countries or is it more rigorous.
The research presented in the article plays a pioneering role for studies dealing with the public attitude towards wind energy in Poland. As for the first time the research concentrated on the opinions of residents living in a close vicinity of wind farms. As the result 171 detailed questionnaires (based on monographic method) were collected in three communes located in the Kujawsko-Pomorskie, Łódzkie and Podlaskie Voivodships. The questions covered the issues of wind turbines impact, contacts with turbine owners, as well as inhabitants' opinions on the role of local authorities in the location process. The general attitude of residents towards renewable energy sources was also examined. The inhabitants more frequently than other study respondents pointed to inconveniences and hazards resulting from the turbine operation. Wind power investors are not known to the majority of residents. The inhabitants do not know to whom they should appeal in emergency situations. At the same time they expect additional financial involvement of investors in the commune. The weaknesses of public consultations conducted by municipal authorities, proofed in previous studies, was confirmed. The lack of a proper consultation process seems to be a missed opportunity that could prevent many unjustified claims and social conflicts. In addition, the study showed that the implementation of investments without a local plan has an additional negative impact on the public opinion on the wind farm installations.
The article presents the results of research on the Warsaw Praga Park vegetation based on the i-Tree Eco model. Field work was carried out on 88 test surfaces, 400 m² each, located at 50 meter regular intervals within the park area. The article describes the vegetation structure, with emphasis on trees and shrubs. As regards the trees, number of species, crown coverage, thickness structure, health condition, leaf surface, leaf biomass and the origin of species were estimated. The results of field work concerning the vegetation structures in the Praga Park point out the scale of obtained ecosystem services, which may be expressed in natural units. The issue of ecosystem services is the subject of a separate article from this series.
Urban forest has a significant impact on the conditions and quality of urban area residents’ life (Novak, Crane, 2008). Benefits from urban vegetation, known in the literature as ecosystem services, are now possible to examine and measure thanks to tools such as I-Tree Eco. Studies on the impact of vast urban green areas on climatic conditions and air quality in the city are becoming more and more popular. The results of these studies indicate that green areas act as a kind of filter catching pollutants and can affect the climate not only around their crowns but also at longer distances ranging from 100 to 500 m from their location (McPerson, Rowntree, 1993). The article presents the results of pilot studies based on the i-Tree Eco method applied for ecosystem services provided by the Park Praski in Warsaw.
One condition of rational development of city areas is estimating the value of green and blue infrastructure in addition to the value of technical infrastructure (its value is usually calculated very precisely). Green infrastructure (including trees and shrubbery) is still treated as a free-of-charge unlimited feature, which results in its exclusion from the economic balance of city management. This approach to trees and shrubs was justified when there were no methods of calculating their value. Currently however such methods do exist both in the world and in our country. Using them enables us to evaluate the replacement (structural) value of trees and shrubs. On the basis of structural value it is possible to estimate the accessible ecosystem services such as oxygen production, carbon collection, absorption of pollution, advantages to health, aesthetic values and others. One method designed for estimating structural and functional, and consequently monetary, values of ecosystem services supplied by trees and greenery areas in general is the i-Tree Eco model which enables obtainment of significant and diverse information on distribution and functioning of greenery in cities. This information may constitute an extra source of knowledge about planning and development of city spaces.
