Climate change and risks
Facing climate change and managing risks
Climate change is leading to the greater frequency, intensity, and duration of heat waves, droughts, and extreme precipitation events. Climate seasonality has been disrupted.
As a result, natural risks (e.g., droughts, floods, fires), health risks (e.g., biological invasions, pandemics), and socio-economic risks (e.g., market instability) have increased. There are significant threats to food systems, water resources, soil resources, means of subsistence within populations, infrastructures, human health, and ecosystem health.
INRAE is carrying out interdisciplinary research on the causes and consequences of climate change using experiments, modelling, and long-term observational data. Working with its partners and a diversity of stakeholders, the institute is helping design and implement sustainable solutions to the transitions that the world must undertake. These solutions must limit the effects of climate change, fuel adaptations to new conditions, and both prevent and manage climate risks.
Key results
Climate change could jeopardize wine production worldwide. A study shows that 56% of the world’s winegrowing regions could disappear under a 2 °C warming scenario, a number that could rise to 85% if warming reaches 4 °C. However, increasing winegrape diversity within vineyards could halve the potential losses of winegrowing regions in the first scenario and cut losses by a third in the second.
The stability and security of dams are crucial. Whenever there is a problem, research engineer Claudio Carvajal must visit the site and provide immediate support, both short- and long-term, to prevent dangerous situations.
France, the major bread-basket for Western Europe, experienced catastrophic yield losses in 2016. Scientists from INRAE, CNRS and CEA1 have shown that in 2016, and in other years, abnormally high temperatures in late autumn accentuated the negative effect on wheat production of excessive rainfall the next spring. These extreme climatic conditions raise questions regarding both agricultural production systems and the prediction of crop yields.
Our fields of research
Our research focuses on the causes of climate change and its impacts, as well as conceptualising and implementing means for mitigation and adaptation, including carbon sequestration and biomass storage, agrifood system and ecosystem adaptation, and water and resource management. We work on understanding, preventing and managing natural, health and socio-economic risks and how they are interrelated to promote multi-hazard risk management.
