In the inner tropics, glaciers are exclusively found of volcano peaks above unique Andean páramo ecosystems that serve as global biodiversity hotspots, harbor some of the highest carbon stocks per unit area on Earth, and sustain Indigenous agrarian Kichwa communities who have stewarded the land and waters for generations. Glaciers there are fast-disappearing under climate change, yet the vast majority of studies on glacier retreat and downstream impacts are concentrated in mid- to high-latitudes. With Ecuadorian collaborators at academic, governmental, and community institutions, the project’s overarching research objective is to determine how climate change drives glacier retreat on culturally and ecologically critical Andean volcanoes in the inner tropics, triggering impacts on water supply, vegetation and land-use, and elemental feedbacks to the climate. To ensure benefits to Kichwa stewards of the páramos, the approach includes co-production of predictive models of future change with the historically marginalized Kichwa communities living at the mountain bases. Engagement with the communities will yield a framework for ethically weaving together Indigenous and scientific understandings of earth systems–which is lacking in the Andes. Closer to home, at and around the U.S. home institutions, the project will develop activities for Indigenous university science students and Latin American/Indigenous high school students to help them face achievement gaps for science careers while acknowledging their heritage. Through collaboration events, the project team, as participants of the Global North’s disproportionate contributions to global change, endeavors to fulfill their obligations to Indigenous peoples, lands, and water in the Global South, in their own states, and with implications for science-Indigenous community partnerships elsewhere.This project provides the first systematic investigation on glacier mass balance processes in the inner tropics, models the consequences of accelerated plant succession in deglacierized landscapes, and implements the first assessment of sulfur and metals controls on páramo carbon stores. Its interdisciplinary work plan will further uncover hidden subsurface flow paths of meltwater that influence the timing of stream discharge and the weathering and export of solutes; demonstrate complex feedbacks among plant succession, soil moisture dynamics, soil development, and nutrient release under climate change and land management scenarios; provide spatiotemporally resolved hydro-biogeochemical process-understanding to determine whether vast páramo carbon stores will become a source of greenhouse gases to the atmosphere; and finally show how climate-driven glacier retreat triggers responses that propagate throughout mountain catchments to affect water, plants, and elemental cycles. The project’s integrative approach combines field and remote sensing observations, laboratory analyses, and computational modeling, and knowledge co-production with Kichwa communities. In addition to producing extensive multidisciplinary datasets and predictive integrative models in a data-sparse and fast-changing region of the world, centering Indigenous community engagement creates a novel opportunity for Andean Indigenous knowledge to be in dialogue with conventional academic science, which can transform conceptualizations of earth science.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在内部热带地区，冰川仅在独特的安丹·帕拉莫（AndeanPáramo）生态系统上方的火山峰上发现，这些生态系统是全球生物多样性热点，拥有地球上人均地区的一些最高碳库存，并维持土著农业农业基奇瓦社区，这些社区为世代相传。冰川在气候变化下是快速陈述，但是绝大多数关于冰川静修和下游影响的研究集中在中高腹膜中。借助厄瓜多尔的学术，政府和社区机构的合作者，该项目的总体研究目标是确定气候变化如何驱动冰川在内部热带地区对文化和生态批判性的安第斯火山的冰川撤退，从而触发了对供水，植被和土地用途以及对气候的元素反馈的影响。为了确保对Páramos的Kichwa管家的好处，该方法包括与历史上边缘化的Kichwa社区共同生产未来变化的预测模型。与社区的互动将产生一个框架，以道德上编织的土著和科学理解对地球系统 - 安第斯山脉中缺乏的地球系统。该项目靠近国内，在美国家庭机构及其周围，为土著大学科学专业的学生和拉丁美洲/土著高中生开发活动，以帮助他们面对科学职业的成就差距，同时承认自己的遗产。通过协作活动，项目团队作为全球北部对全球变化的不成比例贡献的参与者，努力履行对本地南部，国家，本国南部，本地南方土著人，土地和水的义务，以及在其他地方的科学社区伙伴关系的影响，对这一领域的首次系统性投资。冰川化的景观，并在Páramo碳存储上进行了首次评估硫和金属对照。它的跨学科工作计划将进一步发现融化的隐藏的地下流动路径，这些融合会影响流排放的时机以及固体的风化和出口；在气候变化和土地管理方案下，展示了植物继承，土壤水分动态，土壤发育和养分释放之间的复杂反馈；提供空间分辨的水力地球化学过程 - 确定庞大的Páramo碳存储是否会成为大气中的温室气体的来源；最后显示，气候驱动的冰川静修会如何触发整个山流域的反应，以影响水，植物和元素周期。该项目的综合方法结合了现场和遥感观察，实验室分析以及计算建模以及知识共同生产的知识与Kichwa社区。除了在数据范围和快速变化的世界中生产广泛的多学科数据集和预测的综合模型外，以土著社区参与为中心，为安第斯本地知识与传统学术科学进行对话创造了一个新的机会影响审查标准。
