In semiarid blown-sand areas under aridification, water preservation is a particularly crucial task for agriculture. The international Diverfarming project (2017–2022), within the EU Horizon 2020 Program, focused on the impacts of crop diversification and low-input practices in all pedoclimatic regions of Europe. In this three-year experiment conducted in the Pannonian region, the impact of intercropping asparagus with different herbs on some provisioning and regulating ecosystem services was evaluated in the Kiskunság sand regions. Relying on findings based on a range of measured physical and chemical soil parameters and on crop yields and qualitative properties, advice was formulated for farmers. The message drawn from the experiment is somewhat ambiguous. The local farmers agree that crop diversification improves soil quality, but deny that it would directly influence farm competitiveness, which primarily depends on cultivation costs (such as fertilization, plant protection, and labour). Further analyses are needed to prove the long-term benefits of diversification through enriching soil microbial life and through the possible reduction of fertilizer use, while water demand is kept at a low level and the same crop-quality is ensured.}, year = {2024}, eissn = {2223-7747}, orcid-numbers = {Lóczy, Dénes/0000-0002-2542-6775; Weidinger, Tamás/0000-0001-7500-6579; Horváth, László/0000-0001-5977-288X; Pirkhoffer, Ervin/0000-0003-2917-3290; Czigány, Szabolcs/0000-0002-9158-3162} } @article{MTMT:34206012, title = {The evolution of meandering rivers in sedimentary basins: Insights from the lower Drava (Hungary/Croatia)}, url = {https://m2.mtmt.hu/api/publication/34206012}, author = {Słowik, Marcin and Dezső, József and Salem, Ali and Puhl-Rezsek, Marietta and Gałka, Mariusz and Kovács, János}, doi = {10.1002/esp.5726}, journal-iso = {EARTH SURF PROCESS LANDF}, journal = {EARTH SURFACE PROCESSES AND LANDFORMS}, volume = {49}, unique-id = {34206012}, issn = {0197-9337}, abstract = {Rivers flowing through sedimentary basins are subjected to a variety of controls. The main goal of our study was to identify the effect of external (e.g. climate changes, tectonics) and internal controls (e.g. sediment transport, deposition, vegetation cover) on the evolution of meandering rivers flowing through sedimentary basins using the example of the lower Drava River (Europe, Hungary/Croatia). Field research was conducted along a 50‐km‐long section of the valley. Sedimentary data from boreholes and corings, 35 km of ground‐penetrating radar surveys and analyses of digital maps were conducted to reconstruct channel planform changes. Traces of four meander belts were identified, and 39 AMS radiocarbon dates were used to distinguish the chronology of the fluvial events. The evolution of the lower Drava River comprised alternating periods of deposition (formation of aggrading meander belt) and avulsions. The channel belts were formed owing to upstream sediment delivery and floodplain storage. Changes in climate humidity and the occurrence of high flows influenced the planform of the meanders within particular channel belts. The oldest channel was active at least ~40 000 cal. BP before being reworked by subsequent meanders active between the Late Pleniglacial (30 000–14 700 cal. BP) and Late Glacial (~11 000 cal. BP) periods. The channel belts shifted to the south in the Holocene, between ~11 000 and 250 cal. BP due to the presence of a thrust fault situated diagonally to the Drava Valley. Results show channel width, channel belt width and the surface area of point bar deposits increased in the succeeding generations of meanders and that the style and sedimentary architecture of the channel belts were dominantly dependent on autogenic controls, that is, sediment delivery, aggradation and erosional events (e.g. formation of chute cut‐offs).}, year = {2024}, eissn = {1096-9837}, pages = {642-663}, orcid-numbers = {Słowik, Marcin/0000-0001-8376-3414; Salem, Ali/0000-0001-6176-8345; Kovács, János/0000-0001-7742-5515} } @article{MTMT:33790264, title = {Integrated assessment of the impact of land use changes on groundwater recharge and groundwater level in the Drava floodplain, Hungary}, url = {https://m2.mtmt.hu/api/publication/33790264}, author = {Salem, Ali and Abduljaleel, Yasir and Dezső, József and Lóczy, Dénes}, doi = {10.1038/s41598-022-21259-4}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {33790264}, issn = {2045-2322}, abstract = {Land-use/land-cover (LULC) change is considered a key human factor influencing groundwater recharge in floodplains. Without accurate estimations, the impact of LULC change on water balance components may be either significantly understated or exaggerated. This paper assesses the impacts of LULC changes from 1990 to 2018 on water balance components and groundwater levels of the Drava floodplain, Hungary, where human interference has led to a critical environmental situation. In this study, a spatially-distributed water balance model (WetSpass-M), and a groundwater flow model (MODFLOW-NWT) were integrated to assess the impacts of LULC changes. The moderate expansion of built-up areas increased surface runoff, while the afforestation of arable land and meadows and the overgrowth of bare mudflats with willow shrubs increased evapotranspiration. As a consequence, total annual groundwater recharge decreased by 5.3 × 10 7 m 3 in the floodplain with an average of 335 mm year −1 and 317 mm year −1 in 2012 and 2018, respectively. Moreover, an average groundwater level decline by 0.1 m is observed in the same period. Declined groundwater recharge, increased runoff, and evapotranspiration exerted a negative effect on water resources in the Drava basin. The approach tested in this paper allows temporal and spatial estimation of hydrological components under the changes of LULC, providing quantitative information for decision-makers and stakeholders to implement efficient and sustainable management of water resources in the Drava floodplain.

Among them Dd, Rt and Rr had a direct impact on flash flood generation, while A , Re, Fa, Ff, k and GC are in inverse relationship with the intensity of flash floods.

The flash flood susceptibility ranking was empirically verified using hydrological data (20-year water regime obtained from 14 official stream gauges). Our conclusions only partially agree with former observations which may be explained by the particular lithology and morphology of the Mecsek Mountains.
