Abstract:The spatial footprint of individual run-of-river (RoR) hydropower facilities is smaller than reservoir-storage hydroelectric projects and their impacts to aquatic ecosystems are often assumed to be negligible. However, these effects are poorly understood, especially for salmonids whose freshwater habitat often overlaps with RoR hydropower potential. Flow regulation for RoR hydropower is unique in how it influences the seasonality and magnitude of flow diversion and because low-head dams can be overtopped at high flows. Based on a review of the primary literature, we identified three pathways of effects by which RoR hydropower may influence salmonids: reduction of flow, presence of low-head dams impounding rivers, and anthropogenic flow fluctuations. We synthesized empirical evidence of effects of RoR hydropower on river ecosystems from 31 papers, of which only 10 explicitly considered salmonids. We identified key research gaps including impacts of extended low-flow periods, anthropogenic flow fluctuations, and cumulative effects of multiple RoR projects. Filling these gaps is necessary to help manage and conserve salmonid populations in the face of the growing global demand for small-scale hydropower.Résumé : L'empreinte spatiale individuelle des centrales hydroélectriques au fil de l'eau est moindre que celle des centrales hydroélectriques avec réservoirs de retenue et, en conséquence, leurs impacts sur les écosystèmes aquatiques sont souvent jugés négligeables. Par contre, leurs effets écologiques sont peu connus, particulièrement pour les salmonidés dont l'habitat en eau douce coïncide souvent avec le potentiel hydroélectrique des centrales au fil de l'eau. La régulation des eaux par les centrales au fil de l'eau se distingue par son influence sur la saisonnalité et l'ampleur de la déviation des eaux, et parce que les barrages de basse-chute peuvent être submergés lors des crues. À la lumière d'un examen des sources documentaires primaires, nous avons cerné trois voies principales par lesquelles la production d'électricité des centrales au fil de l'eau peut influencer les salmonidés, soit la réduction des débits, la présence de barrages de basse-chute sur les rivières et des fluctuations d'origine humaine des débits. Nous avons produit une synthèse des résultats empiriques de 31 études portant sur les effets de la production d'hydroélectricité des centrales au fil de l'eau sur les écosystèmes lentiques, dont seulement dix s'intéressaient explicitement aux salmonidés. Nous avons cerné d'importantes lacunes dans les connaissances actuelles, dont l'impact de périodes prolongées de faible débit, des fluctuations d'origine humaine des débits et des effets cumulatifs de plusieurs centrales au fil de l'eau. Il est nécessaire de combler ces lacunes pour soutenir la gestion et la conservation durables des populations de salmonidés dans un contexte de demande mondiale croissante pour la production d'hydroélectricité à petite échelle.

“…In China, Xie et al (2001) modified Costanza's coefficients to account for unique characteristics of the Chinese socioeconomic and environmental ecosystem, and obtained an equivalence table for terrestrial ecosystems (Xie et al, 2001(Xie et al, , 2003. Since then, many scholars have assessed the value of different types of ecosystem services for environments such as cities, wetlands, and farmland using Costanza's or Xie's coefficients (Gee and Burkhard, 2010;Huang et al, 2010;Kreuter et al, 2001;Li and Ren, 2008;Tong et al, 2007;Van Eekeren et al, 2010;Wang et al, 2010). Till now, some evaluation approaches and models, such as market valuation, hedonic property price, travel cost, contingent valuation, cost-based approaches, replacement costs, stated preference methods, alternative scenarios and integrated valuation of ecosystem Services and Tradeoffs (InVEST) model, were developed and applied for ecosystem services (Nelson et al, 2009;Gómez-Baggethun et al, 2010;Li et al, 2011;Polasky et al, 2011;Calvet-Mir et al, 2012;Viglizzo et al, 2012;Gómez-Baggethun and Barton, 2013).…”

a b s t r a c tMuch of the world is experiencing fast urbanization. Many peri-urban open spaces, such as parks, forest, farmland, and wetlands, have been built over, which has resulted in a steep decline of ecosystem services at the municipal and regional levels. Using remote sensing, geography information system (GIS) technology and economic evaluation method for ecosystem services, the evolution of landscape spatial structure in 1991, 1996, 2001 and 2006 of Changzhou City, People's Republic of China, was obtained and the change of ecosystem services resulted from land use change was evaluated. Study results show a continuing expansion of urbanized areas and reduction in ecosystem services. Before 2001, farmland was the main type of land use, accounting for more than 53.3% of the total area within the broadlydrawn municipal boundaries. In 2006, farmland and built-up areas were the main land-use types. The built-up area increased by 122% from 1991 to 2006. From 1991 to 2001, the proportion of ecological land (farmland, forests, grasslands, and water-covered areas) within Changzhou's municipal boundaries decreased 24.1%. Based on the observed changes, the economic value of ecosystem services provided by Changzhou's ecological land decreased by 19.3% from 1991 to 2006 and the annual decrease ratio was approximately 1.3%. Conversion of farmland to other uses was responsible for the largest reduction in the value of ecosystem services, equal to 239.8 million RMB (equivalent to USD 37.8 million). Our research results were already adopted locally by Changzhou Municipal Bureau of Urban Planning and applied for Changzhou Mater Urban Planning. The current study can contribute not only to improvements in the Changzhou environment, but to the study of and improvements to other rapidly-urbanizing cities, as the rapid growth of urban areas is one of the most pronounced environmental trends of recent times.

“…Hydropower development can come with trade-offs to other industry sectors that also gain benefit from nature such as forestry or agriculture, but the full cost and accounting of economic benefits/trade-offs is not fully understood or incorporated into many land management decisions (Wang et al 2010). Management decisions such as this evoke trade-offs between ecosystem service types, where there can be many unforeseen and undesired trade-offs considering provisioning ecosystem services against other ecosystem service types (i.e.…”

Context An ecosystem service approach for land-use or conservation decisions normally uses economic or biophysical assessments for valuating nature's services. In contrast, even though ecosystem services are required for human well-being, the actual use of services by differing stakeholder groups are rarely considered in typical ecosystem service assessments, especially the more intangible, cultural ecosystem services.Objectives The aim of this research was to quantify different uses for 15 cultural and provisioning ecosystem service indicators across seven stakeholder groups in a watershed proposed with large hydroelectric dam development. MethodsWe used a large-scale survey to quantify use and frequency of use for ecosystem services. Results We demonstrate that different stakeholder groups use ecosystem services differently, both in terms of specific ecosystem service indicators, as well as for frequency of ecosystem service use. Across all stakeholder groups, specific cultural ecosystem services were consistently more important to participants when compared to provisioning ecosystem services, especially aesthetic/scenic values. Conclusions This work is of global importance as it highlights the importance of considering cultural ecosystem services (e.g. aesthetic/scenic, sense-ofplace values) along with multiple stakeholder groups to identify the trade-offs and synergies during decision-making processes for land-use or conservation initiatives.
