Agriculture Resource Management Plans (ARMPs) are the primary programmatic-level planning document for the management of tribal rangelands in North America. This project compares a standard ARMP product with a prototype ARMP developed through a Structured Decision Making (SDM) PrOACT framework in the context of the Navajo Partitioned Lands (NPL). The SDM approach provided increased transparency for the integration of stakeholder values, a systematic method to integrating climate change (CC) planning and traditional ecological knowledge (TEK), and more rigorous and quantitative methods for applying scientific information to the decision problem. Notably, the SDM framework included modeling the consequences and evaluating...
Here, we examine the spatial patterns of (mis)alignment between climate-related risks and risk perceptions across the conterminous US and discuss how (mis)alignment may affect climate efforts in these places. We use public data describing county-level US public perceptions of personal climate risk developed by the Yale Program on Climate Change Communication and derived via a multilevel regression with post-stratification on a national survey (Howe et al 2015) (figure 1(A)) and publicly available hazard risk data from the Federal Emergency Management Agency National Risk Index that quantifies and rates expected annual economic loss resulting from climate-related hazards (Zuzak et al 2021) for five major hazards...

Perhaps once considered dry, unproductive and unremarkable landscapes, America’s rangelands are increasingly recognized as invaluable cultural and ecological systems as they become progressively threatened by climate change. Water scarcity and wildfire across the western United States is expected to increase in severity and frequency due to climate change (Schoennagel et al., 2017). The economies of rural rangeland communities rely on agriculture and recreation, and the semi-arid landscapes are home to unique ecological communities. With careful stewardship, rangelands maintain soils, watersheds and carbon storage, but poor management can degrade wildlife habitat and destroy biodiversity (McNeeley et al., 2017)....
Water resource managers face the complex challenge of balancing water allocation between human and environmental needs. Declining water availability in many regions globally is driven by over- allocation and usage by municipal and agricultural users and climate-driven changes in rainfall. At the same time, environmental flows in rivers and streams that sustain fish and other aquatic life are decreasing for the same reasons. Because freshwater species’ populations are declining rapidly, it is increasingly important to balance between human and environmental water needs. However, there are significant barriers and socio-political issues that prevent water from being allocated to conserve freshwater ecosystems. This...
Fire in Southern California chaparral communities is a historically common occurrence [1]. Hot, dry summers interact with strong “Santa Ana” winds and large human interfaces to create extreme risks of devastating wildfires [6], [11]. These plant communities also feedback into wildfire probabilities, producing drought-resistance mechanisms – such as volatile oils and woody stems - that can increase the spread and intensity of wildfire [1], [13]. Understanding the main drivers of wildfire is a priority in the wake of recent drought conditions, which are likely to worsen. California experienced its most extreme drought of the last millennia during the 2012-2016 period [5]. These extreme conditions interact with an...

By amassing a database of climate adaptation strategies and looking at overall resiliency outcomes or short-term measures of success, such as spatiotemporal increases in population size or biodiversity, a meta-analysis can better connect the science-to-policy interface and present as a decision-support tool. By synthesizing results from a case-scenario meta-analysis and investigating if these strategies involve components of the National Wildlife Federation’s Climate Smart Conservation Cycle, we can provide a framework for effective conservation strategy by explaining how conservation practitioners are using it and if they have deemed it successful. The objective of this project is to compile adaptation case-studies...

The mission of the US Geological Survey’s National Climate Adaptation Science Center (NCASC) is to provide managers, policy-makers, and other stakeholders with information and decision-making tools to respond to effects of climate change on natural resources. In support of this goal, the NCASC has supported exceptional mentoring experiences for graduate students from select partner institutions in developing policy-relevant products related to managing climate change impacts on fish, wildlife, and/or ecosystems. For many graduate students conducting research on the impacts of climate change on natural resources, disseminating results of their research to managers, policy-makers, or other stakeholders is not required...

Playas contribute substantially to biodiversity in the Great Plains by providing habitat and food resources for migratory waterfowl and other wetland dependent species; however, the combination of sedimentation, land use alteration, and climate change threatens this primary function of the wetlands. Within a changing climate, alterations to playa hydro-periods will likely have severe consequences, as playa plants, animals, and nutrient cycling are dependent on regular inundation and drying cycles. Invertebrates, amphibians, and larger wildlife require very specific moisture conditions to proliferate and survive in playas, and plant communities in playas also depend on seasonal precipitation patterns. Thus, changes...
Changes in climate and land-use and land-cover (LULC) are expected to influence surface water runoff and nutrient characteristics of estuarine watersheds, but the extent to which estuaries are vulnerable to altered nutrient loading under future conditions is poorly understood. The present work aims to address this gap through the development of a new vulnerability assessment framework that accounts for (a) estuarine exposure to projected changes in total nitrogen (TN) and total phosphorus (TP) loads as a function of LULC and climate change under several scenarios, (b) sensitivity, and (c) adaptive capacity. The framework was applied to 112 estuaries and their contributing watersheds across the contiguous U.S., specifically...

The present project aimed to assess estuarine vulnerability to water quality change under future climate and land-use conditions and develop a national-scale, interactive, web-based application to facilitate data access and visualization of estuarine systems across the conterminous US.
