The process used to create the ensemble of hydroclimate simulations can be interpreted as an “ensemble of opportunities”, in the sense that the simulation sampling depends to a large extent on the resources and interest of each contributing research centre.

The results of this project will provide decision-makers with a better understanding of the risks related to extreme flood events in both gauged and ungauged areas. Annual peak flow distributions for spring and summer-autumn flood periods will be used to drive the hydraulic models in the flood zone mapping process.

The expected results will enable decision makers on the east coast of North America to better plan future needs for emergency response and equipment in the event of snowstorms.

This recent Arctic regional climate portrait provides decision-makers with climate data for sectors that are not covered by the observation stations generally used.

The results of preliminary simulations and theory support the idea that forest management could accelerate the response of forest stands to climate change. Opening the forest canopy accelerates succession by modifying competition interactions within the stand.

Accounting and evaluating diverse interests can be formally integrated in decision aid processes such as MCDA and can be used to help structure and make more informed decisions, especially in the context of limited resources.

Québec’s municipal managers, professionals and planners have a new tool oriented to their needs at their disposal for assessing and mapping population vulnerability to heat waves and hydrometeorological hazards.

The methods developed can be applied in other major cities in Québec to support climate change adaptation and health-focused land use planning.

Update of useful resources for characterizing and analyzing communities from the point of view of vulnerabilities to the psychosocial impacts of extreme weather events.

The project raised awareness among water managers about the problem of ice jam flood risk. This initial analysis helped better define the issues and guide the search for relevant adaptation measures.

This project led to a better understanding of different target audiences and their interest in content relating to the fight against climate change.

The project identified concrete legal mechanisms for dealing with exceptional hydrological variations as well as their benefits and limitations in the context of climate change.

The project made municipalities and MRCs more aware of the impacts of certain land use planning and water management decisions. Each participating community has increased its autonomy in dealing with the impacts of the issues to which they are exposed.

The projections from the project serve to identify plausible risks and protect human health and the shellfish industry in the Estuary and Gulf of St. Lawrence.

The future portrait of 81 climate indicators for the territory of Nunavik will drive a variety of climate change impact and adaptation studies, including studies on the food security of Aboriginal populations and fauna/ecosystem modelling. The use of alternative data made it possible to produce finer subdivisions of northern bioclimate, which may serve as a baseline for ecologists.

A notable outcome are the 2013 and 2015 editions of the Hydroclimatic Atlas of Central Québec by Direction de l’Expertise hydrique (MDDELCC) providing profound insight into the future modifications of the hydrology of Québec.

The approach developed provides decision-makers with a decision-making aid process that summarizes the results of the model. 

The results will enable forest managers to assess the extent to which forestry can be developed in these northern areas and using which practices, taking into account natural disturbances influenced by climate change. In addition, better anticipation of the consequences of climate change will improve the ability to manage the forest in such a way as to maintain productive stands and thereby achieve sustainable forest management.
