Wetland evapotranspiration

and –

A wetland is an environment where water is readily available for vegetation, and therefore intensive evapotranspiration (ET) close to the potential ET value occurs. In addition, higher ET intensities can be expected in the future due to the observed increase in temperatures associated with climate change. The impact of wetland ET needs to be considered, for example, in restoration planning or hydrological mod-elling, and it is important to draw on the current knowledge provided by the large number of papers worldwide.

Xenobiotic substances in solid matrices of aquatic ecosystems

, , , , and –

Monitoring of substances such as halogenated and other hazardous organic pollutants or heavy metals provides valuable information about environmental pollution. These persistent substances accumulate in both biotic and abiotic compartments, as well as in food chains, and many of them act as human carcinogens and endocrine disruptors. The Czech Hydrometeorological Institute’s annual monitoring results show long-term contamination of surface water ecosystem in the Czech Republic by these substances.

The potential of grass strips for retaining surface runoff and sediment

, , , , , , and –

The use of grass strips in agricultural landscapes is widely recognized for their ability to effectively reduce surface runoff and the transport of eroded particles, while simultaneously enhancing biodiversity and landscape stability. This study aimed to quantify the impact of grass strip length on sediment retention in surface runoff. Experimental measurements were conducted on enclosed plots measuring 8 × 1 metres, each with varying proportions of grass cover to simulate different grass strip widths under real-world conditions.

Grey water footprint of malting barley production

, and –

Agriculture is the world’s main freshwater consumer; it also contributes to its contamination through fertilizers and pesticides. This article focuses on the grey water footprint (GWF) as an environmental indicator assessing the impact of agricultural production on water resources. The study analyses the GWF of malting barley production on an area of 9,674 ha in different regions of the Czech Republic. Special empha-sis is placed on including pesticides in the GWF calculation, as their impact on freshwater ecosystems and human health may exceed the impact of fertilizers. The analysis shows that insecticides have the highest GWF, especially deltamethrin, whose GWF is an order of magnitude higher than that of other agrochemicals. The study highlights the importance of including pesticides in future GWF assess-ments to better assess the environmental impacts of agricultural production and optimize sustainable water resource management strategies. At the same time, the study discusses different approaches to including biologically active substances in grey water footprint models.

Interview with Ivan Tučník, Head of Group Sustainability Asahi Europe & International

How does Radegast Brewery work with water when brewing beer, what are the brewery’s aims regarding sustainability, to what extent does the brewery use the latest technological trends in its production, and why do we like bitter beer in the Czech Republic? The offer to be inter-viewed for our VTEI journal was accepted by Ing. Mgr. et Mgr. Ivan Tučník from Asahi Europe & International; in the Czech Republic, the company owns Radegast, Plzeňský Prazdroj, Velkopopovický Kozel, and many other breweries across Europe.
