Twenty-six water bodies and 10 ponds were selected for this research. Anthropogenic loads were assessed according to pollution sources in individual water catchment basins. It was determined that 50% of the tested water bodies had Ntotal values that did not correspond to the good and very good ecological status classes, and 20% of the tested water bodies had Ptotal values that did not correspond to the good and very good ecological status classes. The lake basins and ponds received the largest amounts of pollution from agricultural sources with total nitrogen at 1554.13 t/year and phosphorus at 1.94 t/year, and from meadows and pastures with total nitrogen at 9.50 t/year and phosphorus at 0.20 t/year. The highest annual load of total nitrogen for lake basins on average per year was from agricultural pollution from arable land (98.85%), and the highest total phosphorus load was also from agricultural pollution from arable land (60%).

The case study used spotlight strip census routes to estimate Brown Hare numbers in a 793 ha hunting district. The habitats, dominated by intensively farmed arable land were also mapped. This is part of a Germany-wide long-term monitoring program of game populations which is carried out by hunters and was initiated by the German Hunters’ Association and the Hunters’ Association of Lower Saxony in 2001.

There is a model of agriculture being implemented in regions of the European Union, which comes close to the global strategy of sustainable intensification of agriculture. The aim of this paper is to identify problems connected with realization of this strategy in family-run agricultural holdings based in Opole Province. The primary source material was collected in 2014 by means of a questionnaire survey conducted in 100 agricultural holdings selected on purpose. Their size exceeds 10 hectares of arable land and they are situated in sub-regions that are representative of the agriculture in Opole Province. On the basis of the research it was concluded that the farmers most often choose a trajectory of development, which consists in enlarging the area of land in their possession. This is realized together with simultaneous provision of additional services for the local environment. In the opinion of the examined farmers, the intensification of production, which is regulated by environmental norms, gives rise to the need of constant learning, as well as optimization of technological potential of specialization. The research confirmed also the farmers’ readiness to participate in institutions of risk management, chiefly in the fund of mutual insurance, in case of natural calamities occur.

Abstract. This paper aims to assess the vulnerability at regional level, the model and the proposed indicators being explicitly intended for an essentially rural region, in this case–Tutova Hills (Eastern Romania). Five categories of variables were taken into account to define the vulnerability components: rural habitat, demographic features, agriculture, environmental quality and emergency situations. For each one, five variables were analyzed and ranked based on the level of determination or subordination. In order to ensure the flexibility of the model and to avoid the criteria duplication in assessing vulnerability, only a single indicator of each category was retained and included in analysis: total number of inhabitants, dependency ratio, weight of arable land on slope categories, weight of land under forestry and road accessibility of villages. The selected indicators were mathematically processed in order to maximize their relevance and to unitary express the results in the spread 0–1. Also, values of each indicator were grouped into four classes, corresponding to the level of vulnerability: low, medium, high and very high. A general index was obtained through the integration of vulnerability factors in an equation based on the geometric mean. Spatial analysis was based on features of the MicroImages TNTmips 7.3. software, which allow the vulnerability mapping. This approach argues and states that vulnerability assessment through indicator-based methods can be made only according to the level and scale of analysis and related to natural or human conditions of a region.
