Climate Change and Water 2021

Extreme events : water and environments

The MiDi (Environments & Diversity) network proposes to focus on the different forms of impacts of climate change via its effect on water. Indeed, if the general trend of global warming is observed in all regions of the world, where are the findings and responses to climate extremes such as droughts, floods, heat waves and sudden and intense rainfall?

This international webinar will take place over three afternoons and will be in English. It is open to the academic world and socio-economic partners concerned by the variability of the water cycle and adaptation to extreme events.

Half a day will be dedicated to the vine and the forest as an object as well as to the particular hydrometeorological extreme that are droughts.

The event will follow the lead of the 1st Climate Change and Water international conference and address the latest developments in research on extreme events, evolution and acceleration of the effects of climate change on the water cycle, understanding extreme weather events and forecasting, adaptation to climate change, management, governance and strategy. Climate change is disrupting the water cycle. Impacts are observed in all environments and socio-ecosystems: forests, soils, lakes, cities, and so on.
