Det fins ikke enkle løsninger for å unngå høymole. Flere tiltak samtidig, over flere år, må til for å kontrollere de livskraftige ugrasplantene. Ulike tiltak er prøvd ut i forsøk forskjellige steder i landet.

The prospects and challenges for non-native tree species (NNTS) in Southeast Europe (SEE) were analyzed using a combination of SWOT Analysis and the Analytic Hierarchy Process (AHP). Preference data from three groups of opinion leaders with extensive knowledge of the silviculture, ecology and impact of climate change on NNTS in SEE (researchers, practitioners and decision-makers) were used. Results revealed that strengths and opportunities for all three analyzed elements outweigh their weaknesses and threats. In the review of silviculture, key strengths and opportunities were identified as high p roductivity, adaptation to afforestation of degraded lands, gap filling in forest ecosystems after the loss of native tree species, and higher volume growth of NNTS compared to native tree species. Strength-Opportunity (SO) elements related to climate change were found to be adaptive management responsiveness to climate change and increased length of growing period, possibility of better-adapted mixtures with NNTS under climate change, and replacement of tree species that are sensitive to pests and outbreaks resulting from climate change. These results provide important insights into different segments of strategy approach of sustainable management of NNTS in relation to management, silviculture and climate change practices in SEE.

The Balaton lake is the focal area of implementing the WFD in Hungary. At present, nutrient loads are primary threat to surface and subsurface water quality in the Balaton watershed. With increasing anthropogenic pressure and increased occurrence of extreme precipitation events in the future the nitrate loads might increase. The goal of this study was to evaluate the combined effect of climate, land use and soil management changes on nitrogen loads in Tetves Creek, which is the tributary of the Balaton lake. We applied the INCA-N (INtegrated CAtchment Model) water quality model to simulate the hydrological processes and nitrate transport for two periods: the current situation (baseline, 2006 to 2015) and for a future period (2046-2055). We calibrated the model against measured discharge and nitrate concentration data. The inorganic nitrogen sub-model was further validated using data of an independent period. The modelling chain was able to reproduce 59% of the variability of average nitrate concentrations in the Tetves Creek for the validation period. After validation, we examined several climate change, land use and nitrogen supply scenarios and their combined effects on runoff and nitrogen loads. Our main conclusions are summarised below.

The evolution of phosphorus (P) management decision support tools (DSTs) and systems (DSS), in support of food and environmental security has been most strongly affected in developed regions by national strategies (i) to optimize levels of plant available P in agricultural soils, and (ii) to mitigate P runoff to water bodies. In the United States, Western Europe, and New Zealand, combinations of regulatory and voluntary strategies, sometimes backed by economic incentives, have often been driven by reactive legislation to protect water bodies. Farmer‐specific DSSs, either based on modeling of P transfer source and transport mechanisms, or when coupled with farm‐specific information or local knowledge, have typically guided best practices, education, and implementation, yet applying DSSs in data poor catchments and/or where user adoption is poor hampers the effectiveness of these systems. Recent developments focused on integrated digital mapping of hydrologically sensitive areas and critical source areas, sometimes using real‐time data and weather forecasting, have rapidly advanced runoff modeling and education. Advances in technology related to monitoring, imaging, sensors, remote sensing, and analytical instrumentation will facilitate the development of DSSs that can predict heterogeneity over wider geographical areas. However, significant challenges remain in developing DSSs that incorporate “big data” in a format that is acceptable to users, and that adequately accounts for catchment variability, farming systems, and farmer behavior. Future efforts will undoubtedly focus on improving efficiency and conserving phosphate rock reserves in the face of future scarcity or prohibitive cost. Most importantly, the principles reviewed here are critical for sustainable agriculture.
