The study deals with material support for practical work in science classes in Slovenian primary schools (grades 1-5). It answers the question of why there are differences in national tests in terms of socioeconomic development of the environment, despite the fact that schools are equally well equipped. There are two groups of teachers: in less-developed regions (N=337) and in more-developed regions (N=160) – the criterion is the “the development risk index.” Material research equipment in Slovenian schools is poor. Socioeconomic development does not affect the perception of problems such as: the lack of materials and equipment, oversized groups, poor spatial conditions, and the absence of an assistant. Equipment is provided by schools, while material is brought by the pupils themselves. Comparison has shown that students in more developed environments bring their own material more frequently, which enables more research activities. It was concluded that despite the fact that the material conditions in all Slovenian schools are similar, there are differences in the development level of inquiry skills. In more-developed regions, students compensate the lack of material by providing aids from their home environment. Key words: environmental impact, material conditions, practical work, primary school, science teacher

Seawater desalination represents an alternative solution to face the challenge of water scarcity in Chile. However, the uncertainty toward potential environmental impacts of desalination plants represent a barrier to achieving water sustainability and socioeconomic development in Chile. This study aimed to assess the quality of environmental monitoring plans (EMP) and determine the aspects to be improved within it, in order to enhance the management of desalination plants during the operation phase and guarantee a sustainable development of the activity. The Environmental Impact Assessments (EIAs) and Environmental Impact Studies for seawater desalination projects published in the Environmental Impact Evaluation System (SEIA) in Chile between 1997 and 2018 were reviewed. The results of the brine production from desalination plants showed a significant increase in the last decade (about 1.6 Mm3 per year estimated according to the projects approved or under implementation). The EMPs data show heterogeneity and increasing requirements over time, which can be attributed to the governmental effort to improve environmental protection. Furthermore, a high frequency of irrelevant descriptors was identified in the current EMPs. The study thus recommended standardizing the environmental requirements included in EMPs based on empiric scientific knowledge to enhance the environmental protection programs in Chile.

The article considers the problem of territorial protection of nature as a factor impeding the socioeconomic development of settlements located within the borders of the Nizhnekhopersky natural park. The key problem of the functioning of regional specially protected natural territories is the contradiction between the need to protect undisturbed natural-territorial complexes and the development of settlement territories that find themselves in the zone of limited economic activity. The development of settlement territories involves the removal of existing restrictions on the civil circulation of land plots, the construction and reconstruction of capital construction facilities. Solving the problem of economic stagnation by adjusting borders and excluding settlements from the natural park entails the need to conduct an environmental impact assessment of future economic activities in areas seized from specially protected natural areas. The forecast assessment of the consequences of possible anthropogenic impacts on the landscapes and ecosystems of the Nizhnekhopersky natural park after changing its area, functional organization and environmental management regimes in the allocated areas was carried out using a modified network method. The results of the research showed that the strengthening of the anthropogenic press as a result of the implementation of measures for the deployment of processing production, the construction of roads and engineering communications (electrification, gasification), housing construction, as well as due to the increase in recreational load, including the spread of uncontrolled recreation, the environmental efficiency of the natural park will naturally decrease.

The study of the environmental impact of water erosion, chemicals and nutrient transport by runoff water is very important to protect soil and water quality. It is possible to find much literature on this topic, but the survey data lack uniformity and represent many different agronomic or natural environments. This is due to the wide range of parameters involved in these phenomena, such as soil and geomorphologic characteristics, tillage and crop management, nutrients and pesticides used. Results of some experiments are presented in this paper. A comparison of water, soil and chemical losses has been made between experimental data and modeling outputs, both at plot and at watershed scale. The findings indicate that monitoring and modeling are two complementary instruments, both necessary for the analysis of agrochemical transport phenomena, and that the proposed methodology is useful to evaluate the related environmental impact under different scenarios.
