The biggest issue here is the disappearance of the glaciers. They serve as reservoirs of fresh water in solid form and melt to supply downstream irrigation for crops.
3Причини
Melting glaciers threaten water supplies. Indeed, the relative importance of glacier melt water in summer can be considerable, contributing for example to 25% of August flows in the basins draining the European Alps, with an area of about 105 km2 and only 1% glacial cover. Their disappearance could be catastrophic for cities located in valleys watered by rivers flowing down from the surrounding mountains and for freshwater fauna. Glacier meltwater also increases in importance during droughts and heat waves.
Flooding can lead in some cases to contamination of freshwater resources and affect drinking water systems.

Les ressources en eau douce jouent un rôle crucial dans le développement économique et social, et les disparités dans l'accès et la gestion de ces ressources peuvent exacerber les inégalités existantes. Une gestion durable et équitable de l'eau est donc essentielle pour promouvoir un développement équilibré et inclusif.
