Population growth and climate change increasingly stress public lands that provide key ecosystem services such as clean water, habitat for plants and animals, and income via tourism and natural resources. To ensure that services remain sustainable, land managers allocate limited resources to alleviate evolving stressors between society and the environment; however, land management decisions are challenged by scientific limitations and inadequate communication among scientists, decision-makers, and the public. This project aims to inform land management decisions by identifying regions that provide stable ecosystem services despite climate change and other human-caused disturbance. The project team – representing climate science, geology, hydrology, social science, and ecology – includes students from a Hispanic-Serving Institution and community colleges. The team will work with decision-makers to develop measurement and prediction technologies to estimate where, how, and when ecosystems may experience irreversible change this century. The project will establish a transferrable method to map at-risk and sustainable ecosystem services using both science and public priorities to inform land management decisions in the context of a changing climate. The concept of refugia – the mappable landscape units that are buffered from contemporary climate change – is significant to many population segments that value and/or study ecosystem services at the urban-wildland interface. However, no unified framework exists in which to contribute new data or ideas, and there are technical barriers to projecting future conditions, including climate change and other societal pressures. This project will develop novel observations of water, energy and vegetation to improve a next-generation terrestrial model to co-produce refugia estimates through collaboration among land managers, citizens, and cross-disciplinary scientists. It will undertake the complex task of combining public values, land manager input, and an ensemble of climate change projections to co-define refugia characteristics and predict the location and persistence of refugia under climate change and other anthropogenic forcings. The research will produce three specific advances: (1) a convergent blueprint for integrating and defining the value of ecosystem services that are relevant to the public, managers, and scientists as a means to characterize refugia, (2) improved process-based model structure to predict the dynamics, thresholds, and boundaries of future refugia, and (3) a novel modeling framework to separate sources of uncertainty in projections of ecosystem change.This award is co-funded by the Hydrologic Sciences program.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.

人口增长和气候变化对提供关键生态系统服务（例如清洁水、植物和动物栖息地以及通过旅游业和自然资源获得收入）的公共土地造成越来越大的压力。为了确保服务保持可持续性，土地管理者分配有限的资源来缓解不断变化的压力源。然而，土地管理决策受到科学局限性以及科学家、决策者和公众之间沟通不足的挑战，该项目旨在通过确定在气候变化和其他情况下仍能提供稳定生态系统服务的区域来为土地管理决策提供信息。人为干扰——代表气候。科学、地质学、水文学、社会科学和生态学——包括来自西班牙服务机构和社区学院的学生，该团队将与决策者合作开发测量和预测技术，以估计生态系统可能在何处、如何以及何时经历不可逆转。该项目将建立一种可转移的方法，利用科学和公共优先事项来绘制面临风险和可持续的生态系统服务，为气候变化背景下的土地管理决策提供信息。从当代缓冲气候变化——对于许多重视和/或研究城市-荒地交界处的生态系统服务的人群来说意义重大。然而，不存在统一的框架来提供新的数据或想法，并且在预测未来条件方面存在技术障碍，包括。该项目将开发对水、能源和植被的新颖观测，以改进下一代陆地模型，通过土地管理者、公民和跨学科科学家之间的合作共同进行保护区估计。将公众结合起来的复杂任务该研究将产生三项具体进展：（1）收敛蓝图。整合和定义与公众、管理者和科学家相关的生态系统服务的价值，作为描述避难所特征的一种手段，(2) 改进基于过程的模型结构，以预测未来避难所的动态、阈值和边界， (3) 一个新颖的建模框架，用于分离生态系统变化预测中的不确定性来源。该奖项由水文科学计划共同资助。该奖项是 NSF 的法定使命，并通过使用基金会的智力价值进行评估，被认为值得支持以及更广泛的影响审查标准。
