Les sécheresses en Wallonie, un nouveau défi du changement climatique ? Quelques pistes pour améliorer la gestion de ce phénomène. ; Droughts in Wallonia, a new challenge of climate change ? Some ways of improving the management of this meteorogical phenomenon.
peer reviewed ; In recent years, droughts - extreme climatic events due to abnormal rainfall deficits - have become a regular occurrence in our latitudes. With its slow dynamics, wide scope and numerous multidisciplinary impacts, this atypical phenomenon is likely to cause both a simple environmental disruption and a major socio-economic crisis. Moreover, it is now certain that the ongoing global warming will increase the frequency and intensity of droughts in Europe. Wallonia must therefore prepare for this new climate challenge in order to limit - in the short, medium and long term - its cos... Mehr ...

peer reviewed ; In recent years, droughts - extreme climatic events due to abnormal rainfall deficits - have become a regular occurrence in our latitudes. With its slow dynamics, wide scope and numerous multidisciplinary impacts, this atypical phenomenon is likely to cause both a simple environmental disruption and a major socio-economic crisis. Moreover, it is now certain that the ongoing global warming will increase the frequency and intensity of droughts in Europe. Wallonia must therefore prepare for this new climate challenge in order to limit - in the short, medium and long term - its costly and destructive impacts. Initiatives have already been taken in Belgium at national and regional level to improve the management of this phenomenon, but we show in this article that they are insufficient. Optimising prevention and planning, introducing alert thresholds with concrete measures or promoting adaptation and anticipation are all actions that can increase our resilience to this risk. This article contextualises the risk of drought in Wallonia, makes a non-exhaustive inventory of existing measures and presents some ways for improving the management of drought episodes. ; Ces dernières années, les sécheresses – événements climatiques extrêmes dus à un déficit pluviométrique anormal – s’invitent régulièrement sous nos latitudes. Avec sa dynamique lente, son ampleur large et ses nombreux impacts multidisciplinaires, ce phénomène atypique est susceptible de provoquer aussi bien une simple perturbation environnementale qu’une crise socio-économique majeure. De plus, il est maintenant certain que le réchauffement climatique en cours va augmenter la fréquence et l’intensité des sécheresses en Europe. La Wallonie doit donc se préparer à ce nouveau défi climatique pour en limiter – à court, moyen et long terme – les impacts souvent coûteux et destructeurs. Des initiatives ont déjà été prises en Belgique à l’échelon national et régional pour améliorer la gestion de ce phénomène mais nous démontrons dans cet article ...
