Alpine glaciers worldwide will lose most of their volume by the end of the 21st century, placing alpine ecosystems and human populations at risk. The new lands that emerge from retreating glaciers provide a host of challenges for ecological and human adaptation to climate change. In these novel proglacial landscapes, ecological succession and natural hazards interplay with local agriculture, hydroelectric production, mining activities, and tourism. Research has emphasized the importance of understanding adaptation around socio-environmental systems, but regional and global management efforts that support local initiatives and connect novel proglacial landscapes to ecological, social, and cultural conservation opportunities are rare and nascent. The characteristics of these emerging lands reflect the nexus of alpine ecosystems with socio-political histories. Often overlooked in glacial-influenced systems are the interdependencies, feedbacks, and tradeoffs between these biophysical systems and local populations. There is no coordinated strategy to manage and anticipate these shifting dynamics, while affirming local practices and contexts. There is an opportunity to initiate a new conversation and co-create a governance structure around these novel landscapes and develop a new framework suitable to the Anthropocene era. This article first synthesizes the rapid socio-environmental changes that are occurring in proglacial landscapes. Second, we consider the need for integrating “bottom-up” with “top-down” approaches for the sustainable management of proglacial landscapes. Finally, we propose establishing a transdisciplinary initiative with policy-related goals to further dialogues around the governance and sustainable management of proglacial landscapes. We call for increased cooperation between actors, sectors, and regions, favoring multiscale and integrated approaches.

需要对因气候变化造成的冰川消融而暴露的土地进行管理

到 21 世纪末，全世界的高山冰川将失去大部分体积，使高山生态系统和人类处于危险之中。从退缩的冰川中出现的新土地为生态和人类适应气候变化带来了许多挑战。在这些新的冰川景观中，生态演替和自然灾害与当地农业、水力发电、采矿活动和旅游业相互作用。研究强调了了解围绕社会环境系统进行适应的重要性，但支持地方倡议并将新的冰川景观与生态、社会和文化保护机会联系起来的区域和全球管理努力是罕见的和新生的。这些新兴土地的特征反映了高山生态系统与社会政治历史的联系。在受冰川影响的系统中经常被忽视的是这些生物物理系统和当地人口之间的相互依赖、反馈和权衡。没有协调的战略来管理和预测这些变化的动态，同时肯定当地的做法和背景。有机会围绕这些新颖的景观发起新的对话并共同创建治理结构，并开发适合人类世时代的新框架。本文首先综合了前冰期景观中正在发生的快速的社会环境变化。其次，我们认为需要将“自下而上”与“自上而下”的方法相结合，以实现对冰川景观的可持续管理。最后，我们建议建立一个具有政策相关目标的跨学科倡议，以进一步围绕滨河景观的治理和可持续管理进行对话。我们呼吁加强行动者、部门和地区之间的合作，支持多尺度和综合方法。
