“…This has a strong influence on HABM interpretation: For example, decrease in sculpin habitat suitability mostly concerns the North of the catchment because sculpin occurs (and will occur) less in the South. This demonstrates the importance of interpreting habitat simulations in a wider ecological context, which was not always done in previous HABM applications at large scales (Damiani et al, 2019). Incorporating directly the effect of hydraulic habitat changes in SDM construction would be attractive but remains currently challenging.…”

“…For example, models based on ‘species–discharge’ relationships (i.e., correlations between species richness in catchments and discharge at their mouths) have been used to predict fish species loss globally (Iwasaki et al, 2012; Xenopoulos & Lodge, 2006). Predictions by these large‐scale correlative approaches can be influenced by non‐causal correlations that make them unrealistic (Damiani et al, 2019; Tedesco et al, 2013). In particular, intercorrelations between catchment discharge, total and wetted areas and temperature may influence large‐scale predictions.…”

Approaches available for estimating the ecological impacts of climate change on aquatic communities in river networks range from detailed mechanistic models applicable locally to correlative approaches applicable globally. Among them, hydraulic habitat models (HABMs) link hydraulic models of streams with biological models that reflect how organisms select microhabitat hydraulics. Coarser but more general species distribution models (SDMs) predict changes in geographic distributions; they

“…More accurate AHG exponents may be particularly useful for predicting the ecological effects of relative changes in discharge in stream reaches. For example, Damiani et al (2019) showed that, for aquatic communities across French reaches, the width exponent b is a key driver of the sensitivity of habitat suitability to water abstraction. Therefore, further developments of AHG models should contribute to improved environmental flow and river management studies.…”

“…For example, hydraulic estimations across catchments have been used for quantifying habitat alteration due to discharge alteration at national or regional scales (Miguel et al, 2016; Snelder et al, 2011). Damiani et al (2019) used hydraulic estimations across the French network, in the context of “life cycle assessment” approaches, to quantify the ecological impacts of water consumption; they showed that habitats are more sensitive to water abstraction in small streams than in large ones. Hydraulic variations in catchments were also estimated to study water temperature in a large catchment (Beaufort et al, 2016), nutrients fluxes in France (Dupas et al, 2013), sediment transport in an Australian catchment (Russell et al, 2018), pollutant fluxes in an Italian catchment (Whelan et al, 1999), streambed hydraulic conductivity in French stream network (Stewardson et al, 2016), flood risk in an Australian catchment (Grimaldi et al, 2018), or pathogens fluxes at the global scale (Vermeulen et al, 2019).…”

Reach-scale at-a-station hydraulic geometry (AHG) relationships are power laws that describe variations of reach-averaged water depth, wetted width, and current velocity in stream reaches when discharge varies. Modeling AHG exponents is important, because the variations of hydraulics with discharge in stream networks influence physical habitats of aquatic species, biodiversity, water temperature, nutrient fluxes, and sediment transport. Theoretical approaches indicated that AHG exponents should depend on topographic descriptors of cross sections and roughness elements. Empirical approaches suggested that AHG exponents partly depend on hydraulic characteristics measured at a single discharge. We used a unique data set of AHG observed in 812 stream reaches (obtained from measurements at several discharge rates or from hydrodynamic models) to (1) test the consistency of theoretical and empirical predictions of AHG exponents and (2) test the generality of AHG predictions across rivers of different countries with variable landscape settings. We found that observed AHG depended on topographic predictors (describing cross-section shape and substrate size) as expected from theory. However, AHG exponents were better predicted by empirical hydraulic characteristics of reaches: the ratio of wetted width to bankfull width and the reach Froude number. The effects of hydraulic variables were consistent with those of topographic predictors. In addition, relations between AHG and hydraulic predictors were significant and with similar direction in different data sets. Despite limited explanatory power, our results help identifying general drivers of AHG exponents. Their application still requires measurements at a single discharge rate but open perspectives of generalized AHG prediction by remote sensing.

“…Eutrophication is also a critical subject among the midpoint indices in life cycle impact assessment (LCIA) ( Cosme & Hauschild, 2017 ; Rosenbaum et al, 2017 ). TN and TP concentrations in water directly affect this problem ( Chapra, 2008 ), while other features, such as water consumption, are also effective on freshwater ecosystems, aquatic habitat or eutrophication intensification ( Damiani et al, 2019 ). Since it is difficult to evaluate the eutrophication potential of agricultural systems, a combined method is required for the CIA of nutrients release from farmlands ( Ortiz-Reyes & Anex, 2018 ).…”

Background Best management practices (BMPs) are promising solutions that can partially control pollution discharged from farmlands. These strategies, like fertilizer reduction and using filter strips, mainly control nutrient (N and P) pollution loads in basins. However, they have secondary impacts on nutrition production and ecosystem. This study develops a method to evaluate the cumulative environmental impacts of BMPs. It also introduces and calculates food’s environmental footprint (FEF) for accounting the total environmental damages per nutrition production. Methods This study combines the soil and water assessment tool (SWAT) for basin simulation with the indices of ReCiPe, a life cycle impact assessment (LCIA) method. By these means, the effectiveness of BMPs on pollution loads, production yields, and water footprints (WFs) are evaluated and converted as equivalent environmental damages. This method was verified in Zrebar Lake, western Iran. Here, water consumption, as WFs, and eutrophication are the main indices that are converted into equivalent health and ecological impairments. Two methods, entropy and environmental performance index (EPI), are used for weighting normalized endpoints in last step. Results Results showed that using 25–50% less fertilizer and water for irrigation combined with vegetated filter strips reduce N and P pollution about 34–60% and 8–21%, respectively. These can decrease ecosystem damages by 5–9% and health risks by 7–14%. Here, freshwater eutrophication is a more critical damage in ecosystem. However, using less fertilizer adversely reduces total nutrition production by 1.7–3.7%. It means that BMPs can decline total ecological damages and health risks, which threatens nutrition production. FEF presents a tool to solve this dilemma about the sustainability of BMPs. In the study area, a 4–9% decrease in FEF means that BMPs are more environmental friendly than nutrition menacing. Finally, this study concludes that SWAT-ReCiPe with FEF provides a quantitative framework for environment-food nexus assessment. However, due to the uncertainties, this method is recommended as a tool for comparing management strategies instead of reporting certain values.
