This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Landsliding is a complex process that influences carbon budgets in mountainscapes worldwide. This interdisciplinary project seeks to understand the relative contribution of landsliding and deforestation to land-cover change and ultimately, their role in transferring and storing organic carbon in the Sierra de Las Minas, Guatemala. Using a set of contrasting watersheds - dry and wet - this project will address three primary goals: 1) quantify the contribution of deforestation and landsliding to land-cover change, 2) examine the coupling between landslides and streams, and 3) estimate carbon fluxes associated with landsliding and deforestation. Land-cover data obtained from remotely sensed images taken at many points in time, and carbon-content data obtained from field sampling of vegetation, soil, and water, will be combined in a geographic information system (GIS) to model carbon storages and fluxes. This project will contribute to the education of a new generation of scientists in an emergent field that recognizes important links between Ecology and Earth Sciences. This goal will be accomplished by engaging students traditionally under-represented in science across educational levels in a variety of activities, including field work, satellite image analysis and modeling, and laboratory analyses. Students will also benefit from the cross-cultural aspects of interdisciplinary scientific research in international settings. Results of this project will improve the knowledge base needed for carbon mitigation projects in tropical regions, and will enhance our understanding of carbon cycling and sequestration in the context of climate change, hazard assessment, and forest conservation.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。滑坡是一个复杂的过程，影响着全球山区的碳预算。 这一跨学科项目旨在了解滑坡和毁林对土地覆盖变化的相对贡献，并最终了解它们在转移和储存危地马拉Sierra de Las Minas的有机碳方面的作用。 利用一组对比鲜明的流域-干流域和湿流域-该项目将实现三个主要目标：1）量化毁林和滑坡对土地覆盖变化的贡献，2）研究滑坡和溪流之间的耦合，3）估算与滑坡和毁林相关的碳通量。 从多个时间点拍摄的遥感图像中获得的土地覆盖数据，以及从植被、土壤和水的实地取样中获得的碳含量数据，将被合并到一个地理信息系统中，以模拟碳储存和通量。 该项目将有助于在认识到生态学和地球科学之间重要联系的新兴领域教育新一代科学家。 这一目标将通过让传统上在科学教育水平上代表性不足的学生参与各种活动来实现，包括实地考察、卫星图像分析和建模以及实验室分析。 学生还将受益于国际环境中跨学科科学研究的跨文化方面。 该项目的成果将改善热带地区碳减排项目所需的知识基础，并将提高我们对气候变化、灾害评估和森林保护背景下的碳循环和固碳的理解。
