尼泊尔上周遭遇灾难性洪灾，造成约900名水电项目工人失踪1，数百人被困在隧道中1。这场灾难暴露了该国水电基础设施面临的严重风险。水电设施损失约700兆瓦，相当于尼泊尔电力容量的10%1。
专家指出，这次灾害反映了喜马拉雅地区气候变暖带来的日益加剧的威胁。奥地利格拉茨大学地球科学家Jakob Steiner表示，当局需要重新审视如何在这些地方进行重建1。喜马拉雅地区的冰川正以加速速度融化，同时永久冻土退化、不稳定斜坡、冰川湖泊和降雨模式变得越来越不规则，这些因素共同增加了洪水、滑坡和泥石流的风险1。
灾难韧性联盟高级总监Ramraj Narasimhan建议，重建工作应着眼于提升服务连续性，包括选择更安全的建设地点、建立备用路线、配置备用电力系统以及改进预警机制1。尼泊尔基础设施总价值约1240亿美元，年均灾害损失接近7.6亿美元1，因此提高抗灾能力和冗余系统设计在重建中尤为重要。
Nepal suffered catastrophic flooding that claimed over 900 lives and left more than 4,700 people missing across Nepal and China combined, with hydroelectric workers particularly affected 1. The disaster destroyed approximately 700 megawatts of hydropower infrastructure, representing roughly 10 percent of the country's total electricity generation capacity 1.
The flooding underscores the escalating climate-related hazards facing the Himalayan region. Glaciers in the area are melting at accelerating rates, while permafrost degradation, unstable slopes, glacial lakes, and increasingly erratic rainfall patterns are intensifying risks of floods, landslides, and debris flows 1. Nepal's infrastructure exposed to climate-driven disasters is valued at $124 billion, with the country experiencing average annual disaster losses approaching $760 million 1.
Experts stress that reconstruction must prioritize resilience rather than simply rebuilding damaged facilities in their original locations. Jakob Steiner, an Earth scientist at the University of Graz in Austria, emphasized that authorities need to fundamentally reconsider reconstruction approaches in these vulnerable areas 1. Ramraj Narasimhan, senior director at the Disaster Resilience Coalition, recommended that rebuilding efforts focus on service continuity through measures including selecting safer construction sites, establishing alternative routes, installing backup power systems, and implementing improved early warning systems 1.
