“…Therefore, ES of surface waters should be managed with regard to hydrologic processes connecting both (Qiu and Turner 2013 ). Although mainly driven by abiotic factors, groundwater ecosystems can provide numerous ES, which is rarely taken into consideration (Griebler and Avramov 2015 ; Pinke et al 2020 ). Groundwater levels have been declining due to direct water abstraction (pumping) for drinking water and irrigation (Gozlan et al 2019 ) for example, but also due to reduced opportunities for recharge.…”

“…The spill-over (zonal/remote) effects of water bodies—effects of water that are detectable across a wider area within their surroundings—are not sufficiently known, e.g. at what distance water bodies can have an effect on microclimate via evaporation, potentially providing climate regulation even at regional scale, or how retaining water in floodplains effects groundwater levels in the surrounding areas in the long run (Bullock and Acreman 2003 ; Pinke et al 2020 ). Changes in local and regional air temperature could be detected and analysed by remote sensing, backed with data provided by local in situ sensors for calibration.…”

Freshwater ecosystems are among the most threatened in the world, while providing numerous essential ecosystem services (ES) to humans. Despite their importance, research on freshwater ecosystem services is limited. Here, we examine how freshwater studies could help to advance ES research and vice versa. We summarize major knowledge gaps and suggest solutions focusing on science and policy in Europe. We found several features that are unique to freshwater ecosystems, but often disregarded in ES assessments. Insufficient transfer of knowledge towards stakeholders is also problematic. Knowledge transfer and implementation seems to be less effective towards South-east Europe. Focusing on the strengths of freshwater research regarding connectivity, across borders, involving multiple actors can help to improve ES research towards a more dynamic, landscape-level approach, which we believe can boost the implementation of the ES concept in freshwater policies. Bridging these gaps can contribute to achieve the ambitious targets of the EU’s Green Deal.

“…The further judgement of the question requires a detailed risk based approach, where hazard, vulnerability and economic value together should define the priority of certain locations [43]. Furthermore, while the drainage system offers only minor-moderate mitigation capacity for certain inland excess water events, on the long run it removes significant amount of water from the affected catchments, resulting in lowering groundwater levels and increasing drought sensitivity [5]. This leads to the water surplus-water scarcity paradox, which was outlined in the Introduction.…”

“…As a result, Hungary became a significant cereal producer in the region [4]. However, the long term negative consequences of this endeavor are also obvious by now: (i) an extensive flood-and excess water defense system is maintained by the state to provide tolerable/near-optimal conditions for rainfed crop cultivation; (ii) this drainage system diverts valuable surface and subsurface water resources out from the country leading to tendentious decrease in groundwater levels [5]; (iii) this trend is unfavorable for the ecological status of both the surface and the subsurface water bodies. (iv) and contrary to that, annual grain yields are highly exposed to climatic factors and groundwater availability [5].…”

During the 20th century in the Hungarian lowlands the emphasis was put on maximizing provisioning ecosystem services (ES), which caused the weakening of regulating and other services. With the growing environmental pressures, it is crucial to apply a more adaptive landscape management. This, however, leads to territorial conflicts, as large areas with water-tolerant land cover (i.e., wetlands, meadows, riparian forests) are needed to buffer extreme hydrological events.We present some findings of the WateRisk project, a research that focused on the possible solutions of these conflicts. In a scenario-based case study, we analyze the outlined issue for the Szamos-Kraszna Interfluve, a 510 km2 lowland catchment heavily affected by excess water. Scenarios were evaluated with an integrated methodology that focuses on the water budget and the total values of ES. The efficiency of the drainage network was found to be minor/moderate as it provided only -1–5% reduction in the spatial extents of inundations, and it contributed only ~20% to the elimination of water coverage. Furthermore, comparing the present (defense-focused) and the alternative (water retention focused) scenarios, the latter turned out to provide higher monetary value for the summed individual and social benefits of ES. This underlines the need for extensive adaptive measures in both water management and landscape planning to create resilience and the ability to cope with contemporary environmental challenges.

“…More complex environmental parameters, such as fluctuations of groundwater level, are rarely taken into account in large scale predictions despite their effect on yield potential having already been proved. In Hungary, maize yield variability was found to be 18-38% dependent on ground water decrease between 1986 and 2010 [70]. Added to the effect of higher temperatures, it has already slowed down crop production during the past decades [71].…”

Aflatoxins (AFs) are harmful secondary metabolites produced by various moulds, among which Aspergillus flavus is the major AF-producer fungus. These mycotoxins have carcinogenic or acute toxigenic effects on both humans and food producing animals and, therefore, the health risks and also the potential economic damages mounted by them have led to legal restrictions, and several countries have set maximum allowable limits for AF contaminations in food and feed. While colonization of food and feed and AF production by A. flavus are highly supported by the climatic conditions in tropical and subtropical geographic regions, countries in the temperate climate zones are also increasingly exposed to AF-derived health risks due to climate change. In the present study, we have reviewed the available mathematical models as risk assessment tools to predict the possibility of A. flavus infection and levels of AF contaminations in maize in a changing climatic environment. After highlighting the benefits and possible future improvements of these models, we summarize the current agricultural practices used to prevent or, at least, mitigate the deleterious consequences of AF contaminations
