Urbanizacja a ochrona i kształtowanie przyrody

100%
In contemporary times urbanization is and extremely rapid process. In all the industrialized and developing countries a continual growth of towns is taking place. The towns increase in number, the area occupied by them becomes larger, and the share of urban population is higher in the total population of the countries. Urban development arises an ever-increasing interest the result of which are numerous researches done by specialists from various sciences and fields, such as sociologists, demographers, economists and geographers, who investigate diverse aspects of urbanization - this phenomenon of our times. In the urbanization studies till now comparatively scarce information is available on the ecological aspects of this process. The author of this paper suggests putting an emphasis on ecological aspects and calls for geographers to join in. The need for a deeper insight into the ecological aspects, in the author’s opinion, results from the following: 1 - a great concentration and intensity of the urban development influence on the nature in urbanized areas, 2 - a vast variety and complexity of these influences, 3 - the influence range and depth of the penetration of human activity on individual components of the environment as a result of a cumulative effect of various technological systems, 4 - accelerated growth rate of the natural processes on the urbanized areas, 5 - the huge scale of man-induced transformation of the nature. The investigation should result in the discoveries of laws and regularities governing the transformations of the natural environment in urbanized areas and to disclose the ways to counteract the negative effects of the progressing urbanization.
Science plays particular role in our days. In contemporary world science became one of the basic factors of social and economic development. The constantly increasing demand on different information makes a necessity of maintainance of adequate social and economic changes. It also creates a necessity of adujstment to these changes working in other regions. Transformation and unification of such information is the result of scientific activity and a social demand on graduate of a different specialities and different level of education. Towns, chiefly the big towns are the nodes of information diffusion, intensification of this diffusion. At the same time the towns are the centres of graduate of a different specialities. The author affirms that correlation between urbanization development and education level of economically active exists. Examination of the so formed phenomena is extremely interesting, mostly because of a cognitive point of view. Such examination is still rare and mostly casual in Polish geography. The paper presents an analysis of education level of economically active population in different size of the town. An evident correlation between town size and increased share of workers with high and average professional education (the bigger town the greater share of workers with high and average professional education) has been claimed. On the other hand no evident correlation has been claimed between the size of the town and a share of workers with the other degree of education. The author suggests the research enlargement taking into consideration the other features (functional type of the towns, situation of the town in different regions) aimed at explanation of existing limitations and to answer the following questions: 1. Is the present system of the structural education profitable as regards realisation of definite social and economic tasks? 2. What sort of education structure in individual and a functional size groups of the towns could be regarded as optimal? 3. What should be done to obtain optimal structure of education if the answer to the questions mentioned above is negative?

Stanisław Marian Leszczycki

100%
Stanisław Marian Leszczycki was born on 8 May 1907, in Mielec. In 1926-1930 he studied geography at the Jagiellonian University under the guidance of professors L. Sawicki and J. Smoleński. In March 1933 he was promoted for a doctor on the basis of his dissertation Geographical research on the settlement in the Insular Beskids. In 1928- 1939 he held the post of an assistant and a senior assistant at the Institute of Geography. As early as in his Cracow years, he was already a true visionary interested in less popular issues of the applied geography (tourism industry, spatial planning, environmental movement). In 1939 he was arrested by the Gestapo during the Sonderaction Krakau "pacificatory" action and sent to the Sachsenhausen concentration camp and later to Dachau. In 1941 he was relieved from the camp due to his very bad health condition and then he worked, among others, in the Municipal Waterworks, in a section of the D.P. 's Assistance; and lectured at the underground Jagiellonian University courses. After the War he made a major contribution toward integration of the geographic societies originating from the pre-war period. The title of his habilitation thesis at the Jagiellonian University was Geographical research on the rural settlement of the Southern Anatolia (1945). After his habilitation procedures, he took the managerial post at the Institute of Geography of the Jagiellonian University and received a title of professor. In 1945-1950 he was actively engaged in politics at the Ministry of Foreign Affairs of the Republic of Poland as Under-Secretary of State (the deputy of the Vice-minister of Foreign Affairs). He participated in the Potsdam Conference as an expert on borders issue. In 1948 he moved to the University of Warsaw where he took the post of the Head of the Department of the Anthropogeography at the Faculty of Humanities. By dint of his efforts the Uruski-Czetwertyński palace was rebuilt for the needs of the University and it houses the Faculty of Geography to the present day. He was the founding father of the Institute of Geography and its director as well as of the Department of the Economic Geography ( 1952- 1970). In 1954 he was nominated a full professor of economics at the University of Warsaw. In 1951 he took actions towards the organization of the Institute of Geography at the Polish Academy of Sciences (PAN) and he performed the duties of its Director until his retirement. At the Polish Academy of Sciences he was the Deputy Scientific Secretary (1952-1957) and one of the presiding officers in 1952- 1968 and 1978-1980. In 1952 he was elected a corresponding member and a full member of the PAN in 1964. As the founder and the chairman of the Committee for Spatial Planning of Poland at the PAN he greatly contributed to strengthening the role of the territorial factor in the economic and social planning. Professor Leszczycki showed great interest and activity in many fields: scientific, didactic, and organizational. He was the initiator, animator, organizer, and the helmsman of Polish geographers' activities. He greatly contributed to the development and consolidation of the Polish geography and to its adequate positioning both in Poland and abroad. He reshaped Polish geography to be more empirical and applied. His greatest achievements refer to the methodology and history of geography; to the geography of manufacturing; to the spatial planning; and to the studies upon the human interaction with the natural environment. The Atlas of the Polish Industry; The National Atlas of Poland; The Atlas of the resources, values, and threads to the geographical environment of Poland were created under his guidance. He published over 1000 papers and promoted 28 doctors. Professor Leszczycki's merits to the development of geography were appreciated as well in Poland as vastly abroad. He obtained a high position in many important international geographic organizations - the International Geographical Union – and he was its Vice-president for two terms and its President in 1968- 1972, as the only Polish geographer in history. In 1988 he was elected a Honorary Prize-winner of the IGU. He was honoured with two national awards ( 1976, 1986), several awards of the Polish Academy of Sciences; and a honorary doctorship of three universities (of the Charles University in Prague, the Economic University in Poznań, and the University of Warsaw). He was also a honorary member of 15 foreign geographical societies. He was decorated with Polish, British, Hungarian, Finnish, Romanian, Bulgarian, and Czechoslovakian medals and orders. Stanisław Leszczycki died in Warsaw on June 13, 1996 and was buricd in Cracow.

The author begins the article with general statements concerning the role of the human element in the development of the region's economy and with the necessity of investigatlng the prognosis of the population structure. Subsequently, the changes that took place in the years 1946-1978 in the population and distribution of populatlon in the Suwałki Province are characterized. Attention is drawn to the fact of levelling the country population and the simultaneous growih of population concentration in towns. Much attention is paid to the changes of biological structures. The author points to the even sex structure whem discussing the population in general aspect and the problems of feminization of town population and masculinizatiion of country population. Much attention is paid to the process of population ageing though it does not occur intensively in the Suwałki Province. Reasons of the existing differentiations and possible consequences of the discussed disproportions are indicated. In the last part of the article, remarks to the discussed changes of professional structure and the degree of utilization of man-power are presented. In the finał part, the author tries to formulate suggestions concerning the future structure of population, distribution of population and its structural features.

Procesy ludnościowe w strefie podmiejskiej Warszawy

63%
The suburban zone of Warsaw is characterized by high density of population caused by increasing attractiveness of Warsaw as the place of location of housing, industrial and service functions. High population density is also enhanced by the development of intensive agriculture (horticultural production, including especially protected crops), requiring high inputs of labour into one unit of land. Specificities of demographic relations in the suburban zone of Warsaw are also reflected in its population structure, characterized by high indices of: feminization, ageing and (broadly conceived) service employment, and in its population dynamics, characterized by low natural increase, positive net migration and the specific form of migration, i.e. job commuting.
