Each year, the Virginia Tech Global Change Center, in collaboration with ISCE, accepts proposals from GCC faculty to support interdisciplinary projects that address social aspects of major global change issues, such as disease, climate, pollution, invasive species and land use. The projects typically leverage and integrate a unique combination of social science expertise with biophysical and/or engineering expertise at Virginia Tech and have a high potential to obtain external funding.

Blooms of the marine dinoflagellate Karenia brevis, generally referred to as "Red tides" (RT), have increased in frequency, intensity, and geographic spread along the Florida gulf coast in recent years. Karenia brevis produces a suite of neurotoxins known as brevetoxins that can result in massive mortalities to fish, birds, and marine mammals. Brevetoxins may also become airborne and travel great distances. In humans, these toxins can produce severe and lasting respiratory irritations. In 2017-2018, the central Florida gulf coast experienced the worst and longest RT episode in decades. This episode has brought issues of mitigation and adaptation to the forefront of scientific and political discussion. The primary objective of this project is to develop a fine spatial scale forecasting system for brevetoxins for the central gulf area that covers a broad coastal band. It will use real-time wind, aerosol concentration, and respiratory effects data, as well as weather forecasts to predict ambient brevetoxin concentrations, for up to 24 hours in advance. To develop, validate, and optimize an RT emissions and transport forecast model, we will couple these environmental data, collected via multiple Unmanned Aerial Systems (UASs) with high-fidelity multiscale atmospheric transport models and other data-driven modeling techniques. The second objective is to determine the socio-economic benefits of such an improved forecasting system to the general population. We will hold on-site focus groups to determine how RT irritation affects local households’ daily life, and how improved forecasting would help them better prepare for these impacts. We will also implement a pilot household survey using choice experiments to determine local citizens’ preferences and willingness-to-pay for improved RT forecasts. The third objective for this project is to foster ties between VT and the Mote Marine Lab in Florida, the premier clearinghouse for RT research in the gulf area.

According to the World Health Organization, mosquito bites result in the death of more than one million people per year due to the diseases they transmit. In Virginia, every summer, thousands of people complain to their local and state government officials about the mosquito problems they encounter. Physical parameters such as temperature, precipitation, and time of the day and year directly affect the biology of mosquitoes and it is the complex interplay of these factors that determines the overall effect of climate on local mosquito populations. Considering ongoing climate change, frequent dramatic weather events, and the ability of mosquito species to invade new areas, it is essential to define the link between climatic changes and the response of mosquito populations. However, despite obvious epidemiological consequences, this link remains understudied in Virginia. Furthermore, only 49% of Virginians think climate change is currently harming or will harm people in Virginia within the next 10 years, suggesting that citizens do not link the climate with vector-borne diseases. We propose to determine the yearly spatial and temporal dynamics of mosquito populations, forecast the potential effects of climate change on these dynamics, and leverage citizen participation to monitor the perception of mosquito nuisance. Our hypothesis is that increases in temperature linked with climate change will affect mosquito population dynamics in Virginia, and that these data can be used to sensitize citizens to potential negative consequences of climate change. We will rely on citizen surveys, mosquito trapping, satellite-derived data and advanced ecological niche modeling to accomplish the project objectives.

While the nexus of public health and climate change is critically important, it is not yet well understood. The fundamental questions we aim to address are: What are the interacting climate-related factors within the built, social, and natural environments that precipitate adverse health outcomes? How can we increase our understanding of these interactions, and devise policy and planning recommendations that respond to them? Answers to these questions are required to create effective adaptation strategies. We aim to develop a novel analytical method leveraging geocoded birth and death records and spatially-resolved environmental datasets. The proposed method uses simulations from a synthetic population model of movements of individuals through space and time to estimate exposure to built, social, and natural environmental factors. Outputs from the synthetic population are then used within a multi-level statistical model to test hypotheses on the associations between health outcomes and environmental conditions.

Water quality (WQ) management directly affects ecosystem health and services, economic growth, and human wellbeing (HWB). However, linkages and conflicts among these concurrent goals are poorly understood, typically not quantified, and not necessarily explicit in discussions of WQ policy. Because WQ management is an integrative, socially negotiated process, the knowledge needed to guide it must be developed through social and ecological lenses. We hypothesize that reducing discordance among stakeholders and increasing transparency in decision-making will both increase public support for and engagement in surface water management, and more completely realize WQ goals. The overall aim of the proposed effort is to explicitly identify potential sources of discord and synergistic opportunities for cooperation in order to develop strategies to better re-align WQ values of local communities with formal management by public agencies. The proposed work will simultaneously build proof-of-concept analytical strategies that can be broadly applied across the US, identify key regions or socio-cultural groups on which to focus future research, and provide preliminary data necessary for conducting a broader co-orientation study aimed at examining concordance in beliefs between WQ experts and local citizens in terms of WQ goals, conditions, and practices. Ultimately, these analyses can guide WQ managers to address shortcomings in public knowledge, communication, and cooperation in order to more efficiently and equitably meet WQ goals.
