Geologia obszarów miejskich : przykłady z aglomeracji warszawskiej

The article presents the attempt to systematize the problems of urban geology using the example of Warsaw agglomeration. The introduction discusses the available literature, both domestic and foreign. It was noted that many authors understand this concept in various ways, defining it differently. This is the result of diverse interests of researchers, whose common point is that their works and research were located in or associated with urban areas. It also presents, in general, the range of subjects and the set of tools related to Earth sciences, which help in solving research tasks. The article makes reference to the constraints associated with availability of the land and problems related to the applicability of methods. It presents the thesis stating that the needs of users of geoinformation in the urban environment are different from the current ones, which were mainly focused on natural resources, rather than on interaction or coexistence of natural resources and development. The recipients of geoinformation in the urban environment, in relation to the presented conceptual scheme, are mainly people or institutions that do not have an appropriate knowledge of geology. Hence, it is necessary to present geoinformation in a clear and accessible manner, as conclusions or guidelines for use. The examples presented in the article prove that geology of urban areas is now becoming a very important part of knowledge necessary for proper, sustainable development of our cities. Over the last few years a significant part of the population moved to urban areas. This trend is noticeable in Poland and around the world.
