1. The correlation between demographic development and land-use changes in SloveniaUroš Horvat, Igor Žiberna, 2020, izvirni znanstveni članek Opis: The paper focuses on determining the degree of correlation between land-use changes and demographic development in Slovenia. The authors conclude that there is still insufficient evidence in the literature for a correlation between these two processes, because quantitative studies addressing these links are very rare and mostly cover small and specific areas. In the case of Slovenia, Spearman’s correlation coefficients are quite low, which confirms that land-use change processes are complex and not dependent solely on individual demographic and socioeconomic factors. Despite the low correlation coefficients, our findings indicate that changes in land use are significantly influenced by changes in age structure and population growth. In areas with population growth the share of arable land is shrinking, whereas in areas with depopulation and a rising aging index the share of partially overgrown land is growing. In the following analysis, the authors focus their analysis on a case study of the Mura and Central Slovenia statistical regions, which lie on opposite poles with regard to development, and thus show differing trends in land-use changes.

2. Lowland forest fragment characteristics and anthropogenic disturbances determine alien plant species richness and compositionMirjana Šipek, Nina Šajna, 2024, izvirni znanstveni članek Opis: Loss of habitat and biological invasion are the main threats to biodiversity. In intensive agricultural or urban landscapes, forest fragments, even if they are small and isolated represent biodiversity refugia. Environmental variables such as landscape structure, abiotic conditions and anthropogenic disturbance affect the biodiversity of the fragments. In this study, we explored plant species richness in 48 forest fragments embedded in predominantly agricultural landscapes on the alluvial plains of the Mura and Drava rivers in NE Slovenia. We determined several forest fragment characteristics such as perimeter, area, shape complexity, length and proportion of edge shared with adjacent land-cover types and anthropogenic disturbance indicated by the presence of footpaths and waste disposed in fragments. The abiotic condition of these fragments was assessed by Ellenberg indicator values. We built generalized linear models and ordination analyses to assess the importance of environmental variables for the richness and composition of alien plant species and other ecologically meaningful plant groups. Shape complexity had a consistent positive effect on the richness of native and alien plants species. Major drivers of alien plant composition in forest fragments included adjacent land-cover and urbanization level. An increasing proportion of arable land along the forest fragment perimeter negatively affected the richness of alien plants, while the effect of urban areas was positive. Our results confirmed that forest fragments in the rural-urban matrix represent biodiversity refugia and support native plant species; however, they are not resistant to invasions; instead invasion depends on the land-cover type in the surroundings of a given forest fragment.

3. Restraints and opportunities of the Romanian rural areasVasile Surd, 2010, pregledni znanstveni članek Opis: Although Romania disposes of an extremely valuable agricultural land, it has proved to be insufficient and irrationally exploited in the last two decades, as a direct consequence of the programme for returning the agricultural areas to the former individual landowners. The lack of technological agricultural means for cultivating the land, its excessive allotment, as well as the rather inappropriate involvement of the political factor in the decision making process and the invasion of imported agricultural products have generated a continuous process of degradation of the rural life as a whole and certain repercussions on the food safety. Currently, more than 50% of the Romanian agricultural area is not being cultivated, while the state imports more than 70% of alimentary products every year.

5. Relations between land-use and socio-economic structure on farms with and without agricultural land abandonmentAndreja Borec, Karmen Pažek, Antonin Flambard, 2005, izvirni znanstveni članek Opis: Agricultural land abandonment and forest expansion is becoming a serious problem in Slovenia. Spontaneous forest expansion has a negative effect on natural and social conditions. Thus the consideration of natural and social conditions is of high importance when talking measures to prevent forest expansion. In the article, the comparison of farms with and without abandonment of agricultural use regarding land-use and socio-economic characteristics was made. The result of test show no statistically significant differences at the 5 % level between farms with and those withoutabandonment of agricultural land regarding socio-economic structure. Analysis of variance ANOVA was used for estimating the difference between various socio-economic structures on farms with abondoned agricultural land. The results of ANOVA show a statistically significant differences (p<0.05) between socio-economic structures on the farms with abandonment of agricultural land. The ANOVA results pointed out that aged farms have the largest abandoned land areas. In order to ascertain the differences between farms with and without abandoned agricultural land regarding their land use structure, t-test was carried out, and its results have shown no statisticallysignificant differences between farms with and those without abandoned agricultural land regarding land-use structure.
