Interests: Vogt’s main research field is hydro-biogeochemical interactions between soil and soil water. He uses a combination of field- and laboratory studies, chemical analysis, statistics as well as mathematical models to study the processes governing mobility, transport, fate and effect of natural and anthropogenic compounds in the environment. Vogt’s research is conducted through truly integrated cooperation with scientists within other fields of science. His current main interest is in unravelling the effects of concurrent pressures governing mobility, transport, fate and effect of contaminants in the environment through biogeochemical processes. His focus is on the role of dissolved natural organic matter (DNOM) in the boreal domain, in which most of the long-range transported pollutants accumulate

Special Issue Information

Dear Colleagues,

Scientists and environmental managers are required to assess the original- and present-state of the environment, and to predict future changes based on climate change, altered land-use, and anthropogenic loading scenarios.

Over-fertilizing causes eutrophication due to increased leaching of nutrients (Phosphorous (P) and reactive Nitrogen (N)) in runoff. Eutrophication has, therefore, become one of the most pervasive water quality problems and the main reason for not fulfilling the requirements for good ecological surface water quality in agricultural districts. Future changes in environmental pressures will have significant impacts on water quality, governed by hydro-biogeochemical processes; e.g., increased surface runoff enhance soil erosion, which increases the influx of nutrients adsorbed to the soil particles. Acid rain changes the ionic strength, as well as sulfate and labile aluminum concentrations, affecting the mobility of dissolved natural organic matter, ferric and ferrous iron, as well as phosphate. Riverbanks and river sediment are also eroded more due to drainage ditching and rapid urbanization.

There is a lack of conceptual knowledge regarding the main hydro-biogeochemical processes governing the transport of nutrients from the terrestrial to the aquatic environment, and how these differ in different environments. This obstructs the identification of key regional factors governing levels and fluxes of nutrient fractions and, thus, our ability to produce tailored models that predict how these will be influenced by changes in the environment. Moreover, it limits our ability to select more targeted and cost-effective abatement measures.

Shedding Light on Increasing Trends of Phosphorus Concentration in Upper Austrian Rivers

Phosphorus (P) impairment of surface waters still represents a major concern worldwide, despite decades of awareness and implementation of remedial measures. In view of this situation, it is all the more necessary to provide decision makers with reliable modelling tools, which can correctly estimate the effect of alternative management strategies. This work tests the performance of the semi-empirical model MONERIS (Modelling of Nutrient Emissions in River Systems) in depicting and quantifying trends of instream total phosphorus (TP) concentration in three catchments located in Upper Austria, a region affected by high agricultural nutrients emissions. The model correctly depicts both the existence of increasing trends (4–µ g TP L − 1 year − 1 ) and the lack thereof (<0.1 µ g TP L − 1 year − 1 ) in different sub-catchments within the period 2001–2014, although it systematically underestimates the trends magnitude. Furthermore, MONERIS together with an optimized data management system has allowed identifying the probable cause of such trends. The results suggest that, despite considerable improvements achieved through enhanced P removal from wastewater and through the implementation of an agri-environmental programme, changes in land use and in cultivated crop types have led to an offsetting increase of erosion-driven emissions. This methodology offers high potential to predict the effect of different management scenarios, but further model fine-tuning concerning erosion and retention processes is required to improve the model accuracy.

Water is a prerequisite for life on our planet. Due to climate change and pollution, water availability for agricultural production, industry and households is increasingly put at risk. With agriculture being the largest water user as well as polluter worldwide, we estimate anthropogenic nitrogen and phosphorus emissions to fresh water related to global crop production at a spatial resolution level of 5 by 5 arc min and calculate the grey water footprints (GWF) related to EU-27′s crop production. A multiregional input-output model is used to trace the the GWF embodied in the final consumption of crop products by the EU-27. The total GWF related to crop production in the EU-27 in 2007 was 1 × 1012 m3/year. Spain contributed about 40% to this total. Production of cereals (wheat, rice and other cereals) take the largest share, accounting for 30% of the GWF, followed by fruits (17%), vegetables (14%), and oil crops (13%). The total agricultural GWF of the EU-27 related to crop consumption was 1830 billion m3/year, which is 3700 m3/year per capita on average. Overall, the EU-27 was able to externalize about 41% of the GWF to the rest of the world through imports of crop products. Full article
