Using Data

In this study, the relationships between normalized difference vegetation index (NDVI) obtained based on MODIS satellite data and grain yield of all cereals, wheat and barley at a country level were analyzed. The analysis was performed by using data from 2010–2018 for 20 European countries, where percentage of cereals is high (at least 35% of the arable land). The analysis was performed for each country separately and for all of the collected data together. The relationships between NDVI and cumulative NDVI (cNDVI) were analyzed by using linear regression. Relationships between NDVI in early spring and grain yield of cereals were very strong for Croatia, Czechia, Germany, Hungary, Latvia, Lithuania, Poland and Slovakia. This means that the yield prediction for these countries can be as far back as 4 months before the harvest. The increase of NDVI in early spring was related to the increase of grain yield by about 0.5–1.6 t/ha. The cumulative of averaged NDVI gives more stable prediction of grain yield per season. For France and Belgium, the relationships between NDVI and grain yield were very weak.

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.

The aim of this study was to integrate component models for tree growth, wind damage, and airflow to assess the consequences of alternative forest-management options on the long-term risk of wind damage on a regional scale. This work could help forest managers to identify possible vulnerable edges and determine the probability of risk for alternative management plans. This new, integrated system was applied to assessing the risk of wind damage over a 20-year period on three alternative management choices. The risk was compared for the current forest edges without creating new edges (case study I) and situations where new edges were created through different clear-cut options (case studies II and III). Case study II represented more intensive cuttings compared with case study III (over four times more timber was cut). It was found that despite intensive cuttings in case study II, only 15% and 7% fewer vulnerable edges were found on average (risk probability class ≥0.1%) in case studies I and III, respectively. Therefore, forest managers must consider the possible risk of wind damage when harvesting timber.
