- PublicationComplex Evaluation Of Air Quality In Rezekne(2015)
; Gotfrīds NoviksPaper presents results of air ionization level measurements made in past 3 years in Rezekne city. The concentrations of positive and negative air ions with mobility factor k ≥ 0,4 cm2/V·s were obtained by portative air-ion counter “Sapfir-3M” (Russia) in 8 parts of the city thrice per day. The approximate interconnections among ionization and chemical and mechanical pollution of air were analyzed. The complex evaluation of long – term air pollution impact on different parts of city is carried out using methods of lichenoindication and air ion research.Scopus© Citations 2 - PublicationRESEARCH OF OAK STANDS IN REZEKNE REGION(2019)
- PublicationOverview Of The River Basin Management Plans In The Baltic Region Under The Waterpraxis Project(2011)
; ; ; Gundars VaļģisThe paper provides brief overview of the river basin district management plans in the Baltic region within the WATERPRAXIS project, linked to the EU Water Framework Directive. Latvian experience in completion of the river basin district management plans is emphasized comparing to other regional cooperation partners. Article is based on the report documents, analysis of the available data and review of the development projects subject to implementation. To some extent also potential issues for discussion are outlined. Certain Baltic countries have had difficulties complying with the EU Water Framework Directive,and there are some potential areas of contention, which should be taken into account in further activities. In course of the administrative and territorial reform and compliance with other EU directives (e.g. in the renewable energy sector) modifications can be made to the status of spatial and also river basin management plans and for the purpose of sustainable development in the region. - PublicationEVALUATION OF BROWNFIELDS IN LATVIA(2009)
; ; ; Ziedonis MiklašēvičsBrownfields (contaminated or degraded territories) significantly pollutes environment, form derelict landscapes and affects people’s security and health. Formation of these sites depends on many factors such as bad industrial practise and economy, inadequate legislation, wastewater and waste management etc. Inventory and evaluation of these sites in Latvia is carried out according to Regulations issued by the Latvia Cabinet of Ministers. The sites are characterised with parameters which differs from accepted in the other European countries. For example, primary classification indicator in Latvia is a degree of ground and soil pollution in these fields and as a secondary factor – presence of destroyed and abandoned buildings. The paper presents the results of investigation the situation on brownfields in Latvia, especially in Rezekne city, analyses the reasons of their formation and develops recommendations for intensification revitalization process of brownfields. - PublicationUrban Development Trends In The Latgale Region At The Beginning Of The 21st Century(2015)The paper provides a comprehensive analysis of urban development trends in the Latgale region, observed at the beginning of the 21st century and to a large extent also outlines the direction of future development. The paper is based on the evaluation of spatial development planning documents,the analysis of the available statistical data and the review of the urban development projects subject to implementation, supplemented by some results of field studies on the urban environment quality. Though the urban environment and partly also the landscape quality has been improved during the last period, as well as in many areas with support of the EU programmes major urban environment development projects are being implemented, however the economic growth is stalling, depopulation processes are not contained, and the regional urban development index is expressly negative. In the course of the administrative and territorial reform the status of the majority of towns and cities of the Latgale region has significantly changed, and sustainable urban development in the region is still under real threat.
- PublicationTOPONYMS AND NAMES OF HISTORICAL PERSONS IN THE PRESENT-DAY URBANONYMS OF LATGALE REGION(2013)Entire set of names presented in the urban area is considered to be urbanonyms – these are the names of address objects (streets, squares, etc.) and the names of other urban objects (parks, hillforts, markets, cemeteries, etc.), as well as the names of separate urban housing estates – both offi cially approved by the authorities and arbitrarily nominated by the population. Urbanonyms are featuring originality of geographical location and particularity of topographical environment of the town or the city, displaying cultural and historical realities, and opening ideological statements of the epoch. In the towns and cities of Latgale during the initial period of formation of the streets, naming thereof has been closely linked to the immediate perception of urban environment and has been taking place spontaneously, by the system of urbanonyms representing territorial features of terrain, type of land use, landscapes and hydrographic network. Urbanonyms in the same way are describing the elements and the most important objects of the urban social and economic infrastructure, for that reason they very often appear also in street names of the towns and cities. The most widely used urbanonym in Latgale is represented by Skolas (School) street, which is found in 13 towns and cities of Latgale region, as the most popular urbanonyms also Baznīcas (Church) (in 10 towns and cities), Parka (Park) and Tirgus (Market) streets (in 9 towns and cities), Dzirnavu (Mill) and Stacijas (Station) streets (in 8 towns and cities) have to be mentioned. Over the 20th century, ideological strata of different powers have had an increasingly high impact on the urbanonyms, for example, more and more frequent naming the streets after notable historic persons or events, in the same way urbanonyms have had to promote emergence of connotations beneficial to the existing power. It is likewise understandable, since urbanonyms are affecting views with regard to the surrounding world of urban residents already since their childhood. It is established that urbanonyms "are the language segment, where ideology of each power is expressed in the most pronounced way” (Balode 2008) and "urbanonyms are national symbols – the same as flag and anthem” (Питкевич 2007). The research is aimed to provide extended characteristics of the Latgale urbanonyms, encompassing all the 14 towns and cities of the Latgale planning region (Balvi, Dagda, Daugavpils, Ilūkste, Kārsava, Krāslava, Līvāni, Ludza, Preiļi, Rēzekne, Subate, Viļaka, Viļāni, Zilupe), as well as Varakļāni belonging to the cultural and historical region of Latgale. Topicalities of the studies of urbanonyms and issues related to their definition and classification are also being dealt with. In-depth analysis is being provided for the use of various categories of place-names or toponyms in contemporaneous urbanonyms of Latgale, trying to reveal also geographical regularities of their selection. Concurrently also various aspects of perpetuation of the memory of historical persons in the street names are discussed – both those reflecting cultural and historical realities of the region and those imposed by ideological settings of different powers. Toponyms are of major importance in street names of the towns and the cities of Latgale – their totality amounts to 132 units, but their frequency of names – 208. Toponyms constitute 17.1 % of total number of the object address names. 81 toponyms or 63.3 % from their total numbers are related to Latgale region, but according to their frequency major proportion is made by names of other Latvian towns and cities. The most frequent toponyms among urbanonyms in Latgale include: Latgale (9 nominations), Rīga (8 nominations), Rēzekne (7 nominations), Daugavpils, Ludza, Jelgava (6 nominations), Vidzeme, Liepāja (5 nominations). In the urbanonyms of Latgale anthroponyms are used significantly less than toponyms, for example, names of historical persons in Latgale are represented only by 84 denominations that make up 6.9 % of their totality. Notwithstanding the fact that after the Republic of Latvia regained its national independence, in many places change of the urbanonyms ideologically unacceptable for the new power has been taking place, the urbanonyms of Latgale still have maintained a comparatively large number of imprints of Soviet ideology - in particular it is typical for Daugavpils as the largest city in the region. Perpetuation into urbanonyms of the names of famous native residents once having lived in particular town or city should be particularly encouraged, thus maintaining live memory of the urban cultural and historical heritage, and also inculcating the feelings of patriotism into townspeople. Urbanonyms with immediate link to the geographical environment, and cultural and historical realities of the territory are providing assistance in highlighting particularity of the region, strengthening historical memory of the socium and promoting a sense of belonging to one’s own place of residence. The article has been developed within the framework of the ESF project No.2009/0227/1DP/1.1.1.2.0/09/APAI/VIAA/071 “Linguo-culturological and Socio- economic Aspects of Territorial Identity in the Development of the Region of Latgale”.
- PublicationTRANSFORMATION OF URBAN LANDSCAPEIN LATGALE REGION ON CHANGE OF 20- 21 CENTURIES(2007)The paper deals with transformation of urban landscape in the 2 cities and 12 towns of Latgale region on change of 20-21 centuries, in the period from 1990 to 2007. Article provides information about factors and social economics processes that have influence on urban landscape structure and quality. The paper have a look at changes of land use structure, demographical processes, urban environmental quality, dynamics of urban transportation system and intensity of construction works in the cities and towns of Latgale region. The results establish disparities between scopes and directions of urban landscape transformation among different ranks of urban settlements.

- PublicationZĪDAIŅU MIRSTĪBA KĀ VIDES KVALITĀTES INDIKATORS LATGALĒ(1999)Zīdaiņu mirstība atšķiras no kopējās iedzīvotāju mirstības problēmas ar savu īpašo sociālo, demogrāfisko un medicīnisko nozīmību. Tā ir viens no jūtīgākajiem jebkuras teritorijas vispārējā sociāli ekonomiskā, sanitārā un ekoloģiskā stāvokļa indikatoriem. Tādējādi zīdaiņu mirstību var uzskatīt par kompleksu vides kvalitātes indikatoru, ar vidi šajā gadījumā saprotot visu sociālo, ekonomisko un dabas faktoru un parādību kopumu, kas tiešā vai netiešā veidā ietekmē iedzīvotāju dzīves kvalitāti.
- PublicationURBANIZATION PROCESSES AND ITS SPECIFICS IN LATGALE(2010)Urbanization is an important demo-geographical process and a complex social phenomenon under impact of which changes are made not only to the global, regional or national settlement systems, but all socio-economic processes are also substantially transformed. Changes caused by urbanization have an impact on traditional way of life, cultural particularity, community and individual psychology and other aspects of spiritual life, therefore expressions and regularities of this process might be of interest not only for demographers, geographers and economists, but also for representatives of the field of humanities. Paper presents the progress of urbanization processes in Latgale, by covering the period from establishment of the first urban-type settlements in the Eastern Latvia until today, when under impact of the depopulation processes number of inhabitants in all cities of the region decreases dramatically. Particular attention is paid to the course of formation and evolution of the Latgale urban network, successively looking at characteristics of the course of urbanization process during all major stages of the historical process. Towns and cities constitute the basis for the Latvian population system, characterized by historically formed relatively dense urban network. Like elsewhere in the country, also in modern Latgale towns and cities are distributed evenly throughout the region area, but historically it has not always been so. Urban spatial and landscape model in Latgale has been developed within the long historical process of gradual accumulation of changes in the landscape space; however the balance of this process is destroyed by sudden transformations of political, economic and socio-cultural conditions the region and its people have had to survive in more than one occasion. The article particularly deals with characteristics of the urbanization processes during post-Soviet period, outlines the present urban development trends in Latgale, and highlights major urban demo-geographical problems, among which the emphasis has to be placed on the rapid depopulation, an ageing population and the deepening of territorial inequalities, also intra-regionally. Structural economical changes and increasing mobility of population during the post- Soviet period have changed the urban development perspective. Activities based on new knowledge are concentrated in large agglomerations, while individual regions, including Latgale, with less competitive urban centers are noticeably lagging behind in their development. Therefore, exactly in these areas and localities it is necessary to strengthen the urban functions to impede also interregional migration of population, since it substantially restricts the functionality of the most remote and underdeveloped areas and hinders provision of services to population at an appropriate level. This is even more important since implementation of the cohesion principles has been proclaimed to be one of the cornerstones of the European Union regional policy. Unfortunately, at least for the time being situation in urban areas of Latgale is far from encouraging - negative net migration and negative natural growth factor, persistently high level of unemployment is observed there, social exclusion and apathy prevailing. Admittedly, in recent years urban development in Latgale represents also several positive trends. Urban environmental quality has improved significantly, which is generally associated with transition to environmentally more friendly fuels and implementation of various environmental projects, based on funding from the EU budget, such as municipal waste management, improving of water supply and sewerage systems. Encouragingly, facilities of regional higher education institutions improve, and the capacity of scientific work increases, important interdisciplinary research has been launched. In the nearest future significant educational and scientific infrastructure improvement projects at the University of Daugavpils and Rezekne Higher Education Institution are planned to be made, which will certainly increase competitiveness of the Latgale region in the science and technology area.</p><p>Article is based on review of comprehensive scientific literature and analysis of available statistical information. The author does not claim to provide all-inclusive and in-depth analysis of the urbanization processes in Latgale, since this task would be performed in course of further studies, but summarizes the results obtained at an early stage of research of urban areas and population demo-geographical development, as well as of the quality of urban environment.
