The worldwide trend of migration from the peripheral rural areas (?rural exodus?) to the central areas of a region raises the question of how to deal with it in some regions of Austria. On the one hand, the loss of population always represents a loss of importance for a municipality, whereas on the other hand, a strong influx puts a strain on the central areas and the increased land consumption poses a challenge for the environment and spatial planners. Depending on the region, this can have various causes, whereby specific pull factors of the central areas as well as a set of push factors of the surroundings are relevant. Within the framework of a study lasting several years and using a mix of selected methods, an attempt was made to work out or characterize those aspects of the female rural lifeworld that represent the decisive factors for shaping the further life paths of women. In this context, the economic structure and organization proved to be particularly important factors for successful economic and land use development, sufficient natural resources, and environmental quality for housing and quality of life as well as a potential for a leisure economy, good accessibility, and infrastructure in terms of transport development and information and telecommunication technologies (distance to the higher-level economic centers is a significant obstacle to development). Finally, cultural values, social trends, and human capital with the existing gender-specific role patterns also play a certain role in the consideration of migration.

This paper studies geomorphometric characteristics of the Al-Shakak drainage basin, which is one of the valleys of the eastern Al-Jazirah region in the eastern parts of the Misan Governorate in southern Iraq. The natural factors, which are represented by surface, geological structure, and climate, have a direct impact on forming these characteristics, such as the stream orders, stream length, mean stream length, bifurcation ratio, stream frequency, drainage density, and channel maintenance. The values of these parameters vary at the level of the main basin and the secondary basins. The total stream orders of the Al-Shakak main basin reached five orders, and their values varied at the level of the secondary basins. As for the lengths of the streams of the main Al-Shakak basin, they reached 175.607 km, most of which were in the large basins. Regarding the average length of the streams, it is measured 0.805 km at the level of the main basin, 0.766 km at the level of the first order, and 0.445 km at the level of the fourth order. The values of the river bifurcation of Al-Shakak basin 1 amount to 3.476, which is the highest value. As for Al-Shakak basin 3, it reached 1.3, which is the lowest value. In addition, the value of the stream frequency of the Al-Shakak basin amounts to 2.253 km/km2, and the drainage density reached 1.786 km/km2, with the channel maintenance being 0.561 km2/km.

This study analyzes the nexus between tourism and regional real growth for European regions at the Nomenclature of territorial units for statistics (NUTS), level 2, for the period 1995-2019. The study uses the dynamic panel threshold model to analyze complex relations between variables. As the dependent variable, we chose real growth rate of regional gross value added at basic prices by NUTS 2 regions. The independent variable is regional arrivals at tourist accommodation, while the control variables are health, household income, and employment at NUTS 2 regional level. The study found the threshold variable for 95% confidence interval. The marginal effects in the low inflation regime are higher compared to marginal effects in the high inflation regime. The study results support tourism-led growth hypothesis, indicating tourism as a one of the main drivers of regional growth. This research contributes to rare literature in application of dynamic panel threshold model in tourism. As an implication, this study can be used as a methodological approach to analyze the impact of different variables (not only tourism, but also innovations, technology, well-being, etc.) on regional growth, especially in countries with high regional differences, such as the Commonwealth of Independent States (CIS), Latin America, etc.

Thufur (earth hummocks) are small periglacial landforms typical for subpolar latitudes, as well as for the high alpine areas at lower latitudes. Their presence in the mountains of the Balkan Peninsula was spotted during the mid-20th century. In this paper we analyze morphometry and morphology of thufur in the context of physio-geographical conditions for their formation. The main aims are to inventorize the thufur in the study area and to determine the physio-geographical factors which enabled their formation at non-zonal elevations. Statistical analysis was performed on the sample of 305 thufur mapped in the field, measuring their circumference, height, and delineating their areas. Classification of the results revealed morphological varieties in terms of horizontal and vertical development. The elevation of the sampling location Ponor is 1,410 m a.s.l., which is considerably lower than the zonal periglaciation in Serbia, at approx. 1,900 m. Therefore, the role of relief as a climate modifier is analyzed in the context of conditions for the azonal development of periglaciation process. Topographical conditions for thufur formation were analyzed through slope inclinations and vertical dissection, determined using the Digital Elevation Model over Europe with 25 m resolution.

Mortality is one of the key determinants of the demographic development of the Republic of Srpska (RS). In the last 20 years, there has been an increase in the mortality rate, especially in the older population. Years of potential life lost (YPLL) were used in this study as a measure of the premature mortality of the population of the RS. The reference age limit is set at 70 years of age, therefore, premature mortality refers to all deaths in the age range from 0 to 69 years. The time frame includes a period of 20 years (1998-2018). The subject of the research is the YPLL analysis of the population of the RS, with a special emphasis on the causes of death. The study aims to determine the differences in YPLL according to gender and cause of death, as well as to indicate the factors influencing differential premature mortality. The results of the research indicate a decrease in YPLL by about 40%. Higher YPLL rates were registered in males. Differentiation according to the cause of death showed low values of YPLL in non-communicable diseases, while high rates were recorded in violent deaths. The decrease in the YPLL rate is a consequence of the reduction of infant mortality and violent deaths, while high values in males are a consequence of the influence of risk factors. Reducing these factors can have a significant impact on reducing YPLL rates among the population of the RS.

This research aims to describe the role of women in education on and utilization of rainwater to increase awareness and insight into water conservation in both the family and community environment. Women are faced with gender differences in the inclusion into the society. Nine respondents participated in this research which consisted of three female community members, three women residents, and three men residents around the Banyu Bening community, Sleman Regency, Yogyakarta, Indonesia. The triangulation of data sources included the community leader, community members, and one of the participating families. The data analysis model used was from Miles and Huberman. The results showed that women played a very important role in the utilization and teaching on rainwater utilization. Women are the main pillars in the success of education and environmental management, especially at the family level. They are the most capable of providing teaching and developing environmental attitudes in their children and the community, and they are also the agents of change and teaching on sustainable environment.

Internal migration is an essential part of regional population change. Driven by various determinants, internal migration has been unequal across time and space. Migration responses to the changes in societal circumstances make it relevant to investigate the spatial and temporal dimension of internal migration in Serbia before and in the aftermath of the COVID-19 pandemic outbreak. The research aims to identify to what extent and in what way the pandemic has changed the magnitude and geographical patterns of internal migration in Serbia. The study is based on additionally processed official statistics on internal migration for the period 2018-2020, from March to December for each year, at the municipal, district (oblast, plural-oblasti), and regional levels. These are aggregate administrative data on usual residence registration by month. The derived data on the net migration rate is cartographically presented using the classification method natural Breaks (Jenks). Spatial dependence was assessed applying the spatial autocorrelation method, based on the Local Moran statistic. The results revealed that the pandemic affected not only the volume of internal migration but also its spatial patterns. The findings present new insights on the role of internal migration in reallocation of population across Serbia before and during the COVID-19 pandemic while underlying the importance of further research to deepen the understanding of internal migration trends upon the COVID-19 outbreak.

This study focuses on the possible impact of forest fires on the destruction of forests in Serbia. The variability of forest fires in NUTS 3 regions in Serbia was investigated. By analyzing the data for the period from 2009 to 2018, it can be concluded that there were pronounced oscillations in the number of forest fires and the size of the burned forest areas. It was determined that during the observed period, the maximum number of fires was recorded in 2012, and the minimum in 2014. The largest burned forest areas were 7,460 ha in 2012 and 2,036 ha in 2011, which is correlated with high air temperatures and lack of precipitation. The damage caused in the forest fire, expressed in m3 for the felled wood mass is the highest in 2012 and the lowest in 2010. The greatest threat to forest fires were in Raska oblast (Uzice) and Zlatiborska oblast (Kraljevo), and the lowest were in Severnobanatska oblast (Kikinda), Zapadnobacka oblast (Sombor), and Srednjobanatska oblast (Zrenjanin). The correlation of forest fire occurrence dynamics and humidity conditions were observed on the basis of statistical indicators of the number of forest fires and the values of Standardized Precipitation Index (SPI). The number of forest fires, depending on the influence of humidity conditions is the highest in the dry season.

Cave entrance data are crucial as the primary indicators in the underground water inventory of a karst area. The data collection was traditionally conducted by field survey, but it is very costly and not efficient. Remote sensing and Geographic Information System (GIS) can help estimate cave entrance locations more efficiently. In this study, variables for cave entrance identification were determined using remote sensing and GIS. In addition, the accuracy of the Cave Entrance Location Model (CELM) derived from binary logistic regression was examined. Several remote sensing and geological data were used including ALOS PALSAR Digital Elevation Model (DEM), Digital Elevation Model Nasional (DEMNAS), topographic and geological map. Topographic elements were extracted by using Toposhape and Topographic Position Index (TPI). Contours derived from the topographic map showed the highest accuracy for extraction of topographic elements compared to ALOS PALSAR DEM and DEMNAS, hence it was used for further analysis. Binary logistic regression was applied to estimate the probability of cave entrance locations based on the variables used. The result shows that three topographic variables: ravine, stream, and midslope drainage had a significant value for estimating cave entrance location. Using these variables, logit equation was formulated to generate a probability map. The result shows that cave entrances are likely to be located in a dry valley. The accuracy assessment using the field data showed that 52.77% of cave entrances are located in medium to high potential areas. This suggests that the moderatehigh potential area can indicate potential water resources in karst area.
溶洞入口资料是岩溶地区地下水资源清查的主要指标。传统的数据收集方式是实地调查，但成本高，效率低。遥感和地理信息系统(GIS)可以帮助更有效地估计洞穴入口的位置。本研究利用遥感和GIS技术确定洞口识别的变量。此外，还检验了二元logistic回归的洞穴入口定位模型(CELM)的准确性。利用ALOS PALSAR数字高程模型(DEM)、国家数字高程模型(DEMNAS)、地形地质图等遥感和地质数据。利用topshape和Topographic Position Index (TPI)提取地形要素。与ALOS PALSAR DEM和DEMNAS相比，从地形图中提取的等高线显示出最高的地形要素提取精度，因此用于进一步分析。根据选取的变量，采用二元逻辑回归方法估计洞口位置的概率。结果表明，峡谷、河流和中坡水系3个地形变量对洞口位置的估计具有重要的参考价值。利用这些变量，建立了logit方程，生成了概率图。结果表明，洞穴入口可能位于干燥的山谷中。利用野外资料进行精度评价，52.77%的溶洞入口位于中、高电位区。说明中高潜力区可作为岩溶地区潜在水资源的指示区。

The data collection was traditionally conducted by field survey, but it is very costly and not efficient. Remote sensing and Geographic Information System (GIS) can help estimate cave entrance locations more efficiently. In this study, variables for cave entrance identification were determined using remote sensing and GIS. In addition, the accuracy of the Cave Entrance Location Model (CELM) derived from binary logistic regression was examined. Several remote sensing and geological data were used including ALOS PALSAR Digital Elevation Model (DEM), Digital Elevation Model Nasional (DEMNAS), topographic and geological map. Topographic elements were extracted by using Toposhape and Topographic Position Index (TPI). Contours derived from the topographic map showed the highest accuracy for extraction of topographic elements compared to ALOS PALSAR DEM and DEMNAS, hence it was used for further analysis. Binary logistic regression was applied to estimate the probability of cave entrance locations based on the variables used. The result shows that three topographic variables: ravine, stream, and midslope drainage had a significant value for estimating cave entrance location. Using these variables, logit equation was formulated to generate a probability map. The result shows that cave entrances are likely to be located in a dry valley. The accuracy assessment using the field data showed that 52.77% of cave entrances are located in medium to high potential areas. This suggests that the moderatehigh potential area can indicate potential water resources in karst area.","PeriodicalId":54076,"journal":{"name":"Journal of the Geographical Institute Jovan Cvijic SASA","volume":"488 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77782139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
