... During the study period, there was a significant increase in the average electrical conductivity (EC) content within the study area, with values rising by 20.0% (Table 2). Particularly, the irrigated Fluvisols exhibited concentrations that were 46.1% higher than the rainfed Fluvisols in 2001/2002 (Table 3), in accordance with the prevailing consensus within the scientific community [22,[64][65][66][67]. This increase in EC is also consistent with the observed decrease in SOM levels, as supported by previous studies [54,68,69]. ...

... The key advantages of the DPSIR framework are (i) applicability to a range of ecosystems (e.g. rivers, lakes) and environmental issues such as eutrophication, water resource management, ecosystem monitoring (Wang et al 2015, Ramos et al 2018; (ii) it is a bridging tool among scientists, policymakers and the stakeholders that adopts interdisciplinary communication and visualization (Karageorgis et al 2005, Niemeijer and de Groot 2006, Helming et al 2012. ...

... The value for I FL9 is 0 because there is a gable roof, which does not produce accumulation of the water and is in good conservation state. The value for I FL10 is considered 35 because the foundation does not present any signs of deterioration that can produce a scouring effect in case of a flood (i.e., good condition, surrounded by sidewalks), and because, according to the database of soils in Portugal [16,17], the soil samples close to the case study are fluvisol, which, is mostly a soil with coarse-grained soils. ...

... In Table S1 of the Supplementary material, the main properties of samples SS1-SS5 and SMO1-SMO5 are summarized. In addition, data related to Portuguese SS samples (PT) were collected from the literature (Alvarenga et al. 2015;Bancessi 2009;Lopes 2017;Mendes 2014;Serrão et al. 2009;Sousa 2005). The number of samples for each toxic metal in PT samples from the literature was Cr (n = 10); Ni (n = 14); Cd (n = 15); Pb (n = 14); Cu (n = 14); and Zn (n = 15). ...

... AMA showed a significant higher amount of ash or minerals when compared to the other species (~ 17%); however, similar values for different AMA species and sugar beet leaves (~ 20%) have been reported [44]. These values are associated to a high presence of minerals such as Fe, Zn, Ca, K, and Mg in AMA [45] and P, K, Ca, Mg, Na, Zn, Cu, Fe, Mn, B, and Mo in sugar beet leaves [46]. From the nutritional point of view and beyond its protein content, AMA leaves could also be considered as a source of micronutrients for human nutrition, mainly in terms of Ca, K and Mg. ...

... The pore connectivity/tortuosity λ parameter was simply set to 0.5 following Mualem (1976). The adopted PTFs were developed using the content of the PROPSOLO database (Gonçalves et al., 2011;Ramos et al., 2013Ramos et al., , 2014a, which includes data on soil basic and hydraulic properties of 697 horizons/layers of 330 soil profiles studied in Portugal. The PTFs were established using multiple regression analysis, with the equations for each MvG parameter determined individually using particle size distribution and the average depth of the soil layer as inputs. ...

... Due to the uncertain effectiveness of such measures and their costs, further research is needed on the impact of conservation tillage on local biodiversity. There is evidence from previous studies that no-tillage cereal farming can reduce soil erosion in this region (Basch et al., 1996; Barreiros et al., 1996). A better understanding of the impact of the adoption of no-tillage systems on the steppic birds' habitat requirements would be a valuable contribution to sustainable regional planning. ...

... Releva, ainda, o facto, de o nível técnico de muitos agricultores ser deficiente e de não existirem estruturas que lhes assegurem um apoio técnico adequado. (Serrão et al., 2003(Serrão et al., /2004Serrão et al., 2006). Para avaliar a durabilidade dos efeitos da LRU, examinaram-se, neste trabalho, a produção e a composição florística da biomassa pratense em quatro ciclos culturais. ...

... We found that event-induced OC export exhibited a consistently greater dominance of POC compared to DOC, across multiple storm events, where the export ratio of POC:DOC ranged between 1.3 and 14.7 (Table 2). To generalize the POC and DOC export pattern beyond our limited data sets, we compiled fluvial OC export data reported in published studies monitoring both DOC and POC during high-flow conditions (Oeurng et al., 2011;Jeong et al., 2012;Caverly et al., 2013;Cerro et al., 2014;Dhillon and Inamdar, 2014;Ramos et al., 2015). These six studies included detailed event characteristics and integrated export for both DOC and POC, and so the OC exports can be normalized based on precipitation and drainage area and be directly compared with our own findings. ...

... Particularly at the basin scale, study findings on the transport of excessive nutrients and sediments by surface flow and the impact of such transport on rivers have provided important information for watershed management [1]. Many studies have shown that rainfall drives as much as 60-92% of the export of sediments and phosphorus [2]. ...
