“…Some of the longest records of increased salinization of urban waters span over a century in Europe [109], and there are similar patterns globally [10]. Urbanization has increased salinization of fresh water via inputs of road salt, wastewater inputs, and industrial discharges (Figure 3).…”

Abstract:The structure, function, and services of urban ecosystems evolve over time scales from seconds to centuries as Earth's population grows, infrastructure ages, and sociopolitical values alter them. In order to systematically study changes over time, the concept of "urban evolution" was proposed. It allows urban planning, management, and restoration to move beyond reactive management to predictive management based on past observations of consistent patterns. Here, we define and review a glossary of core concepts for studying urban evolution, which includes the mechanisms of urban selective pressure and urban adaptation. Urban selective pressure is an environmental or societal driver contributing to urban adaptation. Urban adaptation is the sequential process by which an urban structure, function, or services becomes more fitted to its changing environment or human choices. The role of water is vital to driving urban evolution as demonstrated by historical changes in drainage, sewage flows, hydrologic pulses, and long-term chemistry. In the current paper, we show how hydrologic traits evolve across successive generations of urban ecosystems OPEN ACCESSWater 2015, 7 4064 via shifts in selective pressures and adaptations over time. We explore multiple empirical examples including evolving: (1) urban drainage from stream burial to stormwater management; (2) sewage flows and water quality in response to wastewater treatment; (3) amplification of hydrologic pulses due to the interaction between urbanization and climate variability; and (4) salinization and alkalinization of fresh water due to human inputs and accelerated weathering. Finally, we propose a new conceptual model for the evolution of urban waters from the Industrial Revolution to the present day based on empirical trends and historical information. Ultimately, we propose that water itself is a critical driver of urban evolution that forces urban adaptation, which transforms the structure, function, and services of urban landscapes, waterways, and civilizations over time.

“…The role of spreading was thus threefold: first, it ensured that a by no means negligible share of the nitrogen transported by the sewers did not go into the river; second, it enabled emissions into the river to be spread out over a considerable distance (the effect on the quality of water of the 4200 tN finally rejected would probably have been very different had it depended on the sewer discharges at Clichy and Saint-Denis alone, which are very near to one another); third, the nitrogen discharged at Clichy and Saint-Denis was mainly in ammoniacal form, whereas the sewers transported nitrates for the most part, so again, the impact on the quality of the aquatic environment was modified. These tentative results should be correlated with those of studies of chronicles concerning the river water quality (Cun and Vilagines, 1997) to enable precise analysis of environmental response.…”

Abstract. The aim of this paper is to analyse metabolic interaction between Paris and the Seine during the industrial era, 1790-1970, a period marked by strong population growth, technological changes, and the absence of specific legislation on environmental issues. The viewpoint focuses on exchanges of waters and wastes between city and river, quantifying them and tracing their evolution in the light of the strategies implemented by the stakeholders in charge. The study combines industrial ecology, local history and the history of technology.

“…All these habitat changes are known to favor generalist species (like eurytopic, omnivorous, or phyto-lithophilic species) to the detriment of habitat specialists (Schiemer and Waidbacher 1992;Wolter 2001;Wolter and Arlinghaus 2003). Furthermore, since the end of the nineteenth century, because of the urbanization of the Parisian area, increasing untreated wastewater releases led to a continuous degradation of the water quality reaching a maximum pollution level around 1970 (Cun and Vilagines 1997;Billen et al 2001). During that period, anaerobic or near anaerobic conditions persisted for most of the year over a 100-km long section downstream of Paris, threatening the existence of many fish species (Boët et al 1999).…”

We used historical sources from the end of the nineteenth to the mid-twentieth century and current data to retrace fish assemblage trajectories for the past 150 years on 29 river stretches distributed throughout the Seine River basin. We based our analyses on species presence/absence, occurrence of amphidromous and non-native species, and species ecological traits related to habitat preference, oxygen and temperature requirements, and diet. In accordance with general trends observed for Western Europe, we detected a general decline of amphidromous species and an increase in non-native species, even if, at some sites, several non-native species were extirpated. These changes affecting amphidromous and non-native species led to a weak increase in beta-diversity in fish assemblages. Independently of amphidromous and non-native species, for a reduced set of sites, we noted that changes in the balance of ecological traits over time, trace, in a consistent way, the major steps that affected watercourses like waterway development, increasing pollution, dam construction, or, locally, the recent wastewater treatment improvement. Despite local variations, we found contrasted trends between, on one hand, large rivers and/or catchments which had experienced strong expansion in human population, where fish assemblages had deteriorated, and, on the other hand, upstream catchments, with a declining human population, where fish assemblages showed signs of improvement. Because our results suggested that long-term changes affecting fish assemblages cannot be summarized as an unequivocal gradual degradation, we questioned the use of historical data to define ecological reference conditions for river assessment and management purposes.
