En effectuant depuis de nombreuses années des mesures de l’équivalent en eau liquide de la neige, le SLF contribue à détecter les variations à long terme de notre système climatique.
L'augmentation prévue de la fréquence des incendies de forêt dans le cadre du changement climatique souligne la nécessité d'études à long terme sur la régénération des arbres et la succession des arbres après les incendies de forêt. Ces données servent de base à la gestion adaptative et aux plans d'intervention.
En raison du changement climatique en cours, les extrêmes liés à la sécheresse auront des effets négatifs importants sur l'écologie, l'économie et la santé humaine dans de nombreux domaines, mais ils ont été principalement étudiés séparément dans différentes unités de recherche du WSL.
Ce projet vise à quantifier les flux de carbone dans les sols forestiers le long des gradients de climat et de roche-mère en Suisse et en Allemagne. L'approche consiste à mesurer les teneurs en radiocarbone dans les bassins et les flux de carbone, et à tracer la litière marquée aux isotopes (13C, 15N, 2H) dans le so forestier et dans le sol minéral sous-jacent.

PAMIR is a multi-institutional, interdisciplinary scientific programme funded by the Swiss Polar Institute to understand the state, changes, and consequences of the cryosphere in the Pamir Mountains of Central Asia.
Extremely high river water temperatures introduce thermal stress to aquatic species and reduce the thermal cooling efficiency of power plants, in particular if they persist over time. Despite the potentially severe impacts of such river heatwaves, there exists limited understanding of their occurrence, drivers, future changes, and impacts. The objective of this project is to fill this research gap and improve our understanding of riverine heatwaves in the Alps and Europe.
A major challenge is predicting how ecosystems will respond to climate change. A key knowledge gap limiting our predictive ability is how climate alters the interactions of plants with their enemies.
Food-web structure is likely affected by global change with consequences for biodiversity and ecosystem functioning. In this project we study changes in food webs and nutrient fluxes in response to global change drivers in aquatic, terrestrial and interconnected habitats.
This SPI Exploratory Grant is aimed at equipping the ALTER experiment (Abisko, Sweden) for long-term monitoring of belowground vegetation and microbial dynamics.
In this project we will assess the physiological processes by which trees adjust and interact among each other under a changing climate, determine the consequences of these processes on forest responses to climatic stresses and improve our understanding of these effects on forests functioning at a large comprehensive scale.
GoApply wird zur vertikalen und horizontalen Integration und Weiterentwicklung von nationalen Strategien und Aktionsplänen zur Anpassung an den Klimawandel beitragen.
An increase of extreme environmental disturbances is expected, which is for different reasons a big challenge for forest stakeholders on the operating-, strategic-, financial- and environmental level. Using diverse methods, we aim to describe the complexity of the current problem.
Do evolutionary constraints on photoperiod and circadian clocks hinder adaptation and acclimation of plants to climate change? With this project, we will provide the mechanistic basis and a conceptual framework to understand how climatic and daylight/photoperiod cues jointly affects tree functioning.
We demonstrate optimization pathways of forest management to mitigate climate change.
Future climate change will have drastic effects on mountain forests. We will analyse ancient DNA preserved in natural archives to reconstruct the impact of past rapid climate change on the neutral and adaptive genetic diversity of trees.
Climate change already affects snowfall and snow depth patterns in the Alps, and these changes will likely become more pronounced in the future.
Continuing climate change modifies the water supply and accentuates the pressure from competing water uses.
Less snow, less avalanches? We investigate the influence of climate change on avalanches by using climate projections to model future snow instability for selected representative sites in Switzerland.
Despite being an essential element of the biodiversity and climate change crisis, the feedback between biodiversity and climate remains an understudied subject in biodiversity and climate science. The project FeedBaCks will focus on this important interaction between the two disciplines.
FORWARDS aims to develop, test, and implement a European Observatory that will supply timely and detailed information on European forests' vulnerability to climate change impacts, and provide knowledge to guide climate smart forestry
The objective of the SwissPhenocam project is to develop and implement an automated phenology monitoring tool that will deliver added-value climate services regarding plant phenological responses to ongoing climate change and the carbon and water cycles.
The goal of this project is to take advantage of recently developed avalanche models and detection systems to setup a model framework for avalanche forecasting in Switzerland and to assess changes and uncertainties in avalanche hazard due to climate change.
A large network of research institutions collaborates within an EC-funded Network of Excellence to study the impacts of climate change on forest ecosystems from an evolutionary perspective.
Long-term research on the interactions between changes in land use and climate and their consequences regarding forest health and dynamic in the pine forests at low elevation of Central Alps
The WSL program Climate Change Impacts on Alpine Mass Movements (CCAMM) comprises projects covering a range of topics in natural hazards. Most investigations use models and thus require climate forcing data. The aim of this task is to provide meteorological forcings at the slope scale and in high temporal resolution.
Microclimate is a key factor influencing regeneration in forests. Particularly available light, water supply and temperature determine the success or failure of certain tree species. How will future climate change influence below-canopy microclimate and tree regeneration?
This initiative is aimed to establish a comprehensive European Forest Multifunctionality Monitoring System (EFMMS) that takes on the challenges posed by climate change and environmental stressors. The MoniFun project is a collaborative effort of 13 project partners from 11 European countries.
GenTree aims at providing the European forestry sector with better knowledge, methods and tools for optimizing the management and sustainable use of forest genetic resources in Europe in the context of climate change and continuously evolving demands for forest products and services.
Supraglacial debris considerably alters the response of glaciers to changes in climate, yet debris-covered glaciers are notoriously difficult to delineate due to their fuzzy boundaries and spectral similarities to marginal moraines. Their surfaces are often characterized by supraglacial ponds and ex
The PAPPUS project aims to understand how decision makers influence the choice of plant assemblages and their management in different types of urban green spaces, and how their decisions in turn influence ecological and human benefits in a context of climate change and urban intensification.
With the MULTIBEF project, we aim at taking a holistic view to the study of B-EF relationships, and to investigate climate-change effects on complex B-EF relationships. To this end, we will take advantage of particular freshwater ecosystems tightly linked to forests: water-filled tree holes!
One of the most important questions of climate change impact research today is how glaciers are responding to global warming. ERC-funded, RAVEN aims to determine the role that debris-covered glaciers play in the water cycle of High Mountain Asia and better incorporate processes unique to debris-cove
The chemistry of soil solution and the soil water availability for plants have been monitored since 1997 in seven forest plots in Switzerland. This project, linked to the Swiss Long-term Forest Ecosystem Research project (LWF), aims to assess the soil response to atmospheric pollution (acidifying substances and nitrogen) and to climate change.
In this project we evaluate the effects of multiple combined perturbations on soil biodiversity and functioning. We evaluate perturbations related with climate change (drought and heat wave) and grassland management (fertiliser addition, pesticides, trampling, grazing effects, etc.). We hypothesise that combined perturbations will have synergistic effects with cascading negative effects on soil fauna and microbial communities biodiversity and functionality.
