持续的干旱和高温天气正对欧洲基础设施构成双重威胁。荷兰当局发现,干旱导致泥炭质堤坝含水量下降,堤坝因失去水分而变弱,面临渗漏风险1。这一问题尤为严峻,因为荷兰约三分之一的土地低于海平面1,堤坝的完整性至关重要。这些由泥炭组成的堤坝需要保持潮湿状态才能维持足够的强度1。
莱茵河水位创历史新低,导致河运贸易遭受重创1。莱茵河在科隆的水位已跌至2018年10月创下的历史低位以下1。通常可运载2000至2500吨货物的船只,现在的装载能力大幅下降至仅400至600吨1,严重中断了欧洲的运输链。低水位期也在延长,从过去的一个月扩展至现在的三个月1,加剧了经济影响。农业部门同样受困,荷兰农民面临灌溉禁令1,担忧这会导致产量下降和物价上涨。
Persistent drought and extreme heat across Europe are jeopardizing critical infrastructure and commerce in the region. The Rhine River's water level in Cologne has fallen below the historic low recorded in October 2018, severely constraining barge operations 1. Cargo vessels that normally transport between 2,000 and 2,500 tons are now capable of carrying only 400 to 600 tons, disrupting supply chains across the continent 1.
The low-water periods have extended from roughly one month in previous years to three months currently 1. Dutch authorities have identified a structural vulnerability in their flood defenses: approximately one-third of the Netherlands lies below sea level, and the dikes that protect these regions are primarily composed of peat, which requires adequate moisture to maintain structural integrity 1. The prolonged drought has reduced water content in peat-based dikes, weakening them and increasing the risk of seepage 1.
Agricultural sectors have also suffered under these conditions. Dutch farmers face irrigation restrictions as water scarcity intensifies, raising concerns about reduced fruit yields and potential price increases 1.
