Conséquences du changement climatique sur les eaux en Suisse

Rapport de l'OFEV

Quelles sont les répercussions du changement climatique sur le régime hydrologique, l'écologie des cours d'eau, la protection contre les crues, l'utilisation de l'eau et la protection des eaux ? Pour répondre à ces questions, l'Office fédéral de l'environnement (OFEV), en collaboration avec la communauté scientifique et sur la base des scénarios climatiques CH2018, a élaboré des données de référence hydrologiques et des scénarios pour l'avenir («Hydro-CH2018»). Sur cette base, l’OFEV a analysé, en collaboration avec d’autres services fédéraux concernés, les répercussions sur la gestion des eaux et a déterminé les mesures à prendre pour l’avenir. Ces travaux ont été menés dans le cadre du NCCS et ont porté sur différents secteurs. Le présent rapport offre un aperçu de l’état des connaissances.

Moule Quagga: concept de monitoring et recommandations sur les mesures de prévention et de protection

Brochure de l'Eawag

La moule quagga a été observée pour la première fois dans le lac Léman en 2015. Depuis, cette espèce envahissante originaire du Dniepr s'est rapidement propagée dans les lacs préalpins. Quelles en sont les conséquences pour les écosystèmes et l'approvisionnement régional en eau ?

Les lacs préalpins et l'approvisionnement en eau potable menacés par les moules (langue allemand)

Article du "Umweltwirtschaft" tiré du projet « Seewandel »

Ce rapport formule des recommandations concernant les mesures à prendre pour les cours d'eau non touchés par la moule quagga ainsi que pour ceux qui en sont infestés à un stade précoce de colonisation. L'objectif principal de ces mesures est d'empêcher la propagation de la moule quagga des cours d'eau infestés vers ceux qui ne le sont pas. La deuxième partie contient des recommandations pour la détection précoce ainsi qu'un concept de suivi visant à surveiller à long terme la propagation de la moule quagga en Suisse.

Nos eaux vues d'en haut : un spectacle à couper le souffle (en allemand)

Article tiré de "Wasser Energie Luft"

Dans cet article, nous examinons nos rivières et nos lacs avec un regard d'ensemble, en mettant particulièrement l'accent sur les oiseaux insectivores. Nous montrons que les insectes aquatiques constituent une source de nourriture particulièrement importante en raison des acides gras spécifiques qu'ils contiennent. Il est donc crucial pour les oiseaux insectivores que les insectes aquatiques soient présents en quantité suffisante lors des phases critiques de leur vie, comme par exemple pendant l'élevage des jeunes. Comment la gestion des cours d'eau (par exemple la revitalisation, la protection des cours d'eau, la gestion des bassins versants) peut-elle contribuer à la protection de la diversité aviaire? Article en allemand. 

Diversité remarquable de corégones en Suisse (en allemand)

Brochure de l'Eawag

La diversité des espèces de corégones dans les grands lacs suisses est unique. Les recherches menées au cours des deux dernières décennies sur la diversité des espèces de corégones ont permis de mieux comprendre comment cette diversité s'est développée, comment elle est structurée sur les plans écologique et génétique, et pourquoi de nombreuses espèces ont disparu au cours des 80 dernières années. Ces études ont également montré qu'il convenait de repenser en partie la gestion actuelle de la pêche et de développer de nouvelles approches. Brochure en allemand.

« Projet Lac » - Diversité des espèces piscicoles dans les lacs suisses

Brochure du service de conseil en pêche FIBER

Les lacs des Préalpes et de la périphérie alpine suisses constituent des hauts lieux de biodiversité qui abritent une diversité piscicole unique. De nombreux lacs sont le théâtre d’une pêche professionnelle et récréative profondément ancrée dans l’histoire. Pour garantir une pêche durable et une gestion efficace des stocks halieutiques exploités, il est essentiel de disposer de connaissances détaillées sur la diversité des espèces et la taille des stocks d’un lac. Des prélèvements systématiques effectués dans le cadre du «Projet Lac», une initiative de l’Eawag et de l’Université de Berne en collaboration avec les cantons et l’OFEV, ont permis de recenser plus de 100 espèces de poissons différentes dans les lacs des Préalpes et des marges alpines suisses.

Milieux aquatiques sous surveillance

Publication de la SCNAT - « Hotspot Biodiversité » avec la contribution de l'Eawag

Les cours d'eau constituent des habitats dynamiques. Des facteurs tels que la production d'énergie, l'agriculture, le changement climatique, les eaux usées et les micropolluants montrent à quel point nous les sollicitons. La surveillance permet de mesurer objectivement les évolutions écologiques et, par conséquent, d'en discuter de manière factuelle. La protection et l'exploitation sont le plus souvent en concurrence directe, et pas seulement dans le domaine des cours d'eau. Des données fiables favorisent la transparence et la confiance entre la science, l'administration, le monde politique et le grand public.

Guide pour l'analyse de la consommation d'oxygène et de la production nette de l'écosystème (en allemand)

Publication Eawag & EPFL

Ce guide pratique fournit des indications pour l'analyse de la consommation d'oxygène et de la production nette de l'écosystème dans les lacs. Ces deux paramètres constituent des bases importantes pour évaluer la santé des lacs et permettent d'étudier leur évolution dans le temps. Publication en allemand. 

La modélisation comme outil de gestion des Lacs en Suisse. Exemple du phosphore

Article en "Aqua & Gas" avec la participation de l'Eawag 

L’état global de la qualité des lacs en Suisse a tendance à s’améliorer, mais de nombreux problèmes
d’oxygénation dans le fond des lacs persistent. Ce phénomène, lié aux concentrations actuelles
et passées de phosphore, demeure préoccupant. La modélisation au coeur de cette étude vise à
guider le choix d'approches simples mais appropriées pour la gestion des lacs. Deux exemples
d’applications pour les lacs de Schiffenen et de Baldegg sont illustrés.

Qualité des matières en suspension du Léman. Évaluation écotoxicologique et chimique

Article en "Aqua & Gas"

Les matières en suspension jouent un rôle central dans les lacs en transportant et en stockant divers polluants. Issues des apports du bassin versant ou de processus internes, elles sont à l'interface entre la colonne d’eau et le sédiment. Leur écotoxicité potentielle constitue un indicateur pertinent de l'état de santé global du lac. Grâce à la plateforme LéXPLORE, nous avons réalisé un suivi mensuel de la qualité écotoxicologique et chimique des matières en suspension du Léman pendant une année.

          important to evaluate how seasons and seasonality are represented in lake e
         cosystem research. Here, we used a literature review and global data analysi
         s to synthesize approaches for conceptualizing seasons and seasonality in la

         easons in published literature, including fixed dates (e.g., months, solstic
         e/equinox), environmental thresholds (e.g., temperature and precipitation cu
         toffs), and lake-specific indicators (e.g., ice cover, plankton phenology).
         Analyzing data from lakes worldwide, we found that using different criteria
         to define the same season resulted in divergent interpretations of ecosystem
          states. Based on our synthesis, we offer recommendations for how to incorpo
         rate seasonality into lake research and communications amid global change.

         for toxic (microcystin-producing) versus non-toxic cyanobacteria across temp
         erature gradients in eutrophic Lake Greifen, Switzerland. We conducted month

          non-toxic <em>Microcystis</em> strains at 15 °C and 25 °C.<br />Contrary
         to expectations of cyanobacteria avoidance, zooplankton exhibited predominan
         tly non-selective grazing throughout the seasonal succession, consuming both
          toxic and non-toxic cyanobacteria at similar rates, regardless of temperatu
         re. Notably, during the peaks of phytoplankton abundance (April and Septembe

          monitoring campaign (Greifensee, Switzerland) spanning 150 sampling dates.
         We conducted extensive suspect screening of cyanobacterial metabolites using
          the database CyanoMetDB. Across all 850 samples, 35 metabolites regularly c
         o-occurred. Microcystins were present in 70% of samples, with [d-Asp<sup>3</

         limate change on lakes have often relied on a single model forced with limit
         ed scenario-driven projections of future climate for a relatively small numb
         er of lakes. As a result, our understanding of the effects of climate change
          on lakes is fragmentary, based on scattered studies using different data so
         urces and modelling protocols, and mainly focused on individual lakes or lak

         change on lakes at global and regional scales and has likely contributed to
         the lack of lake water quality considerations in policy-relevant documents,
         such as the Assessment Reports of the Intergovernmental Panel on Climate Cha

         ctor of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) for
          simulating climate change impacts on lakes using an ensemble of lake models

         tions in coastal and ocean waters have been linked to climate warming and hu
         man activity, but little is known about the changes in dissolved oxygen conc
         entrations in lakes. Although the solubility of dissolved oxygen decreases w
         ith increasing water temperatures, long-term lake trajectories are difficult
          to predict. Oxygen losses in warming lakes may be amplified by enhanced dec
         omposition and stronger thermal stratification or oxygen may increase as a r
         esult of enhanced primary production. Here we analyse a combined total of 45
         ,148 dissolved oxygen and temperature profiles and calculate trends for 393
         temperate lakes that span 1941 to 2017. We find that a decline in dissolved
         oxygen is widespread in surface and deep-water habitats. The decline in surf
         ace waters is primarily associated with reduced solubility under warmer wate
         r temperatures, although dissolved oxygen in surface waters increased in a s
         ubset of highly productive warming lakes, probably owing to increasing produ
         ction of phytoplankton. By contrast, the decline in deep waters is associate
         d with stronger thermal stratification and loss of water clarity, but not wi
         th changes in gas solubility. Our results suggest that climate change and de
         clining water clarity have altered the physical and chemical environment of
         lakes. Declines in dissolved oxygen in freshwater are 2.75 to 9.3 times grea
         ter than observed in the world’s oceans and could threaten essential lake

' (89 chars) description => protected'Invasive species can be powerful models for studying contemporary evolution
         in natural environments. As invading organisms often encounter new habitats
         during colonization, they will experience novel selection pressures. Threesp
         ine stickleback (Gasterosteus aculeatus complex) have recently colonized lar
         ge parts of Switzerland and are invasive in Lake Constance. Introduced to se
         veral watersheds roughly 150 years ago, they spread across the Swiss Plateau
          (400–800 m a.s.l.), bringing three divergent hitherto allopatric lineages
          into secondary contact. As stickleback have colonized a variety of differen
         t habitat types during this recent range expansion, the Swiss system is a us
         eful model for studying contemporary evolution with and without secondary co
         ntact. For example, in the Lake Constance region there has been rapid phenot
         ypic and genetic divergence between a lake population and some stream popula
         tions. There is considerable phenotypic variation within the lake population
         , with individuals foraging in and occupying littoral, offshore pelagic, and
          profundal waters, the latter of which is a very unusual habitat for stickle
         back. Furthermore, adults from the lake population can reach up to three tim
         es the size of adults from the surrounding stream populations, and are large
          by comparison to populations globally. Here, we review the historical origi
         ns of the threespine stickleback in Switzerland, and the ecomorphological va
         riation and genomic basis of its invasion in Lake Constance. We also outline
          the potential ecological impacts of this invasion, and highlight the intere
         st for contemporary evolution studies.

' (104 chars) description => protected'Overland transport of recreational boats is among the most important distrib

          such measures are poorly understood and the boat cleaning behavior of boat
         owners has never been studied in detail before the implementation of such pr

         boat cleaning behavior of boat owners in Switzerland where almost no prevent

         ssels attached to their boat and 84% of them cleaning their boat before a tr
         ansport. Nevertheless, only half of the boat owners report using high pressu
         re washing to clean their boat before overland transport and many use ineffe

          on the appropriate methods to remove invasive species from their boat and s
         uggest that high pressure washing facilities should be made available at all
          potentially infested water bodies. Furthermore, our analysis shows that the

          owners value the perceived costs and benefits of cleaning, as well as by in
         creasing their awareness of the potential negative impacts on aquatic ecosys

' (128 chars) description => protected'In aquatic ecosystems invasive species are among the most important threats
         to biodiversity worldwide. Understanding the dispersal mechanisms of aquatic
          invaders is very important for protection and management of vulnerable wate
         r bodies. Here we ask how recreational boats that are transported overland c
         ould contribute to the dispersal of invasive zebra mussels among lakes in Sw
         itzerland. Using a questionnaire sent to registered boat owners, we surveyed
          properties of transported boats and collected information on self-reported
         mussel fouling and transport activities of boat owners. We also sampled boat
          hulls at launching ramps and harbors for biofouling invertebrates. Boats th
         at were kept seasonally or year-round in water were found to have high vecto
         r potential with mussel fouling rates of more than 40 %. However, only abou
         t 6 % of boats belonging to these groups were transported overland to other
          water bodies. Considering that approximately 100,000 recreational boats are
          registered in Switzerland, we estimated that every year around 1400 boats f
         ouled with mussels are transported overland. Such boats pose a high risk of
         distributing zebra mussels between water bodies. Our results suggest that th
         ere is a considerable risk that recreational boats may spread new fouling sp
         ecies to all navigable water bodies within the study area. We speculate that
          one such species could be the quagga mussel, which has not yet invaded lake

          strongly reduced during the period of anthropogenic disturbance and has not

         , depending on the species. Interspecific allele frequency differences of SN

' (136 chars) description => protected'The presence of the oligochaete species <em>Quistadrilus multisetosus</em> (
         Smith, 1900) originating from North America has been mentioned for several d
         ecades in Europe, the Middle East and Russia. Its distribution and abundance
          in Europe is still unknown but it can be considered as potentially invasive
         . This species was recently discovered in Lake Geneva (Switzerland/France) a
         nd three other Swiss lakes. The aims of the present work are to report its r
         epartition and abundance in Lake Geneva, to study its ecology and to determi
         ne its invasive potential in this lake. We also provide an identification ke
         y for correctly differentiating <em>Q. multisetosus</em> from the closely re
         lated species <em>Spirosperma ferox</em> Eisen, 1879 and <em>Embolocephalus
         velutinus</em> (Grube, 1879), and study the phylogenetic position of <em>Q.
         multisetosus</em> within several Tubificinae lineages based on the cytochrom
         e c oxidase (COI) marker. Twenty-eight sites have been monitored since 2009
         in Lake Geneva. In several sites, the COI sequence corresponding to this spe
         cies was also searched for in sediment samples using high-throughput sequenc
         ing. In addition, we examined specimens collected in this lake before 2009 l
         ikely to belong to <em>Q. multisetosus</em> and to have been misidentified.
         We found that <em>Q. multisetosus</em> was only present in the lake downstre
         am of a wastewater treatment plant and a combined sewer overflow in the Vidy
          Bay (near Lausanne) and at a site located nearby. These results confirmed t
         he high tolerance of this species to organic matter pollution. <em>Q. multis
         etosus</em> was already present in this location in 1974 (misidentified as S
         pirosperma ferox), which suggests that <em>Q. multisetosus</em> has a limite
         d capacity to disseminate in this lake. However, we recommend continuing mon
         itoring its presence in Lake Geneva in the future, especially in the context
          of warming of waters that could contribute to the expansion of this species

         are abundant in sediments and comprise sensitive and resistant taxa to pollu

          (PCBs) on these communities has not or insufficiently been studied in lakes
         . Here, we determined the oligochaete and nematode indices at six sites of L

         e importance of altered water quality as a driver of ecological impacts is o
         ften missing from such discussions. This is partly because information on th

         entary, especially for low-latitude developing countries where dam building
         is now concentrated. In this paper, we review and synthesize information on
         the effects of damming on water quality with a special focus on low latitude
         s. We find that two ultimate physical processes drive most water quality cha
         nges: the trapping of sediments and nutrients, and thermal stratification in
          reservoirs. Since stratification emerges as an important driver and there i
         s ambiguity in the literature regarding the stratification behavior of water
          bodies in the tropics, we synthesize data and literature on the 54 largest
         low-latitude reservoirs to assess their mixing behavior using three classifi
         cation schemes. Direct observations from literature as well as classificatio
         ns based on climate and/or morphometry suggest that most, if not all, low-la

         uggests that low-latitude dams have the potential to discharge cooler, anoxi
