Lay Summary (French)

Lead
Les rivières fournissent un nombre important de services pour le bienêtre des hommes engendrant régulièrement des conflits d’intérêts entre plusieurs utilisations dans les domaines de l’agricultures, de l’énergie, des loisirs ou du maintien de la qualité des écosystèmes et de leur biodiversité. Ce projet explore quantitativement et spatialement les impacts attendus dans ces différents services en fonction des changements de climat et d’utilisation du sol attendus.
Lay summary

Alors que les rivières de Suisse semblent être bien connues sous de multiples facettes, peu de modèles ont déjà tenté de modéliser la quantité et la qualité de l’eau de l’ensemble de nos cours d’eau en fonction des conditions climatiques et d’utilisation du sol actuelles, ainsi que celles du futur. Pour y parvenir, il est nécessaire d’inclure un modèle de fonte des glaces et des neiges, ainsi qu’une information sur les nombreuses dérivations artificielles du cours des rivières et des fleuves.

Ce projet propose ainsi d’améliorer nos capacités de modélisation hydrologique à haute résolution et de prédire les impacts des changements attendus sur les services écosystémiques et la biodiversité des rivières. Ces services sont nombreux et appartiennent à différentes catégories comme par exemple l’approvisionnement (énergie hydraulique, agriculture, eau domestique), la régulation (rétention des sols et des engrais, lutte contre les inondations), les valeurs culturelles (loisirs et spiritualité) et le soutien à d’autres services (biodiversité, transport, recyclage des nutriments).

Par cette approche interdisciplinaire, le projet se propose de vérifier dans quelles mesures les objectifs des principales politiques environnementales de Suisse dans le domaine de l’Energie, de l’Eau et de la Biodiversité sont compatibles et atteignables, et quelles sont les éventuels compromis et synergies à entrevoir dans le futur pour maintenir l’ensemble des services actuels.

Abstract

The main objective of the SWATCH21 project is to improve our understanding of and to model hydrologic ecosystem services (supply and demand) at the catchment level on the one hand, and aquatic biodiversity at the river scale on the other hand. The hydrological and ecological models obtained are used to confront the outcomes of climate and land use change scenarios against multiple policy targets. In 2016, the Hydrology Division of the federal Office of the Environment has launched a new focus area to establish a platform for knowledge sharing between researchers and end users in the area of climate change and hydrology. Anticipating on some of the conclusions of this future synthesis, the SWATCH21 project aims at filling some of the expected gaps:•Switzerland is a data-rich country but the data needed to assess hydrologic services and biodiversity is long and difficult to gather;•The impact of glacier and snow melting on hydrological services is not well understood;•The provision of hydrologic services from river catchments has not been assessed across Switzerland;•The impacts of expected environmental changes on river species diversity at the Swiss scale has not been explored; and•The capacity to address multi-sectorial policy targets is weak;In order to address these scientific gaps we defined six main research questions:•How can we improve the access to input data for hydrological and ecological modeling?•What is the role of glacier and snow in modifying the hydrological services?•Can we assess hydrologic services supplies and demands with the available data and tools?•What will be the impact of these changes on species diversity in rivers?•Can we meet the targets of multi-sectorial river-related policies under different climate and land use scenarios?•How detailed do ES data and models need to be to answer relevant policy questions?The general organization of the work program flows from 1) the creation of a tool to facilitate the acquisition of initial condition data; 2)into the glacier and snow melt model; 3) followed by hydrological ES modeling; 4) river species distribution modeling; 5) then the analyses of the impacts of climate and land use scenarios on policy targets translated into ES and biodiversity indicators; 6) and finally the development of a second tool connecting all the different sources of data with the different pieces of software to automate the production of the SWATCH21 outputs.SWATCH21 will provide an integrated solution to access, share, process, model and deliberate on hydrologic ecosystems services. State-of-the-art models will be selected, compared and improved to model different ecosystems and their services. The main outputs of the project will be high-impact scientific publications, as well as many new datasets made available to describe Swiss rivers hydrology, their predicted biodiversity and the related assessment of ecosystem services in terms of provisioning services (e.g. water resources), regulating services (e.g. nutrient and sediment retention, flood protection), and cultural services (e.g. biodiversity, recreation).The main outcome of the project will be to improve the feasibility of integrated evidenced-based water policy in the future. A broader interdisciplinary project incorporating social scientists, economists, geographers and energy experts has been submitted to the Sinergia programme around a Climate-Water-Energy-Ecosystem Nexus approach.
