Primary objective: The School of Natural Sciences and Mathematics
of the University of South Florida (USF) proposes to establish a scholarly focus
area in Global Change Sciences. Researchers and scholars will
work to solve fundamental questions related to rates of environmental/climate change,
both in the past and future, biodiversity, resource assessment and management, and
natural hazards.
A recent area of interest in global change science is also the
effect of industrialization on the environment including the global consequences
of human energy consumption. Research directed at possible means for mitigating
the adverse consequences of fossil-fuel consumption and the development of new materials
for alternative energy sources has gained increased urgency. Science plays
a central role in understanding the natural and anthropogenic processes that drive
global change in climate, ecosystems, sea-level, and a host of complexly interacting
biological and physical systems. SNSM faculty have been extremely active in this
area: publishing at least six reports in Science and Nature on
these topics in the last three years, publishing a great number of articles in disciplinary
journals, and achieving significant external funding. Our goal is to support this
internationally recognized research and further develop USF’s reputation in Global
Change Sciences through focused cluster hires.
Why is this cluster important now?- Global Change Sciences will
play an increasingly central role in NSF directorates related to Geosciences, Biological
Sciences, and related disciplines, and in the priorities set by other funding agencies
such as NASA, EPA, DOE and NOAA. The reason for this is straightforward. The scientific
community has reached consensus that dramatic changes to our planet’s climate and
ecosystems are now underway. Now is the time to improve our understanding of the
physical, chemical, and biological processes driving these changes. The National
Research Council has recently listed grand challenges in Global Change Sciences
to include: biogeochemical cycles, biological diversity and ecosystem functioning,
climate variability, hydrologic forecasting, infectious disease in the environment.
Similarly, the President’s National Science & Technology Council recently listed
grand challenges to understand the natural processes that produce natural hazards
and to develop hazard mitigation strategies and technologies. There is currently
a well- recognized need that addressing issues related to global change will demand
a greater emphasis on analysis of threats and remedies by teams that are interdisciplinary
and that undergraduate education and graduate training should logically follow an
interdisciplinary path. USF needs to capitalize on faculty expertise in these
areas, and hire new faculty to bolster both our international reputation in Global
Change Sciences, and faculty who can focus on regional issues (e.g. Florida and
the Caribbean Basin).
Predicted changes in temperature and precipitation (climate) will have pronounced
effects on ecosystems, mediated by changing distributional patterns of biota and
productivity as well as the delivery of nutrients to support ecosystems. Studies
on paleoclimates offer insight into past climatic events and the response of earth
systems while a focus on erosion and volcanic events provides a glimpse of how landscapes
can be altered and climates impacted over a short period of time. Coastal
areas of the world are particularly vulnerable to changes in climate as alteration
of sea level and weather patterns (hurricanes) can threaten watersheds and adjacent
coastal ecosystems. Because fisheries are dependent on these critical coastal areas,
impacts of global change may have implications for sustaining human populations.
Environmental changes in terrestrial systems are also predicted to accompany global
change with shifts in agriculture, impacts on biodiversity, and spread of disease
and invasive species likely to occur in some geographic settings. Studies
linked to global change will need to quantify better the source and sinks of carbon
both on land and in waters. As we better understand global carbon cycles, there
is an increased interest to reduce pollution from burning fossil fuels and shifts
to new technologies which in turn could lead to both decreased pollution and energy
efficiency and conservation. Likewise, studies of the global water cycle are necessary
to evaluate how changing climate will impact water resources. Improved observational
capacity and monitoring of the earth’s systems along with modeling efforts will
be integral parts of research activities linked to global change.
Why USF? USF is uniquely poised to be among the leading institutions
in the US to make Global Change Sciences a signature field of research/teaching.
A number of factors combine to make this quite plausible with some targeted investment
including:
(a) Location, location, location - USF is one of the few universities
both located in a subtropical climate and in an area with a high
population density. Areas along the west coast of Florida are under rapid urbanization
along with the spreading of human activities that modify the environment.
Human impacts are discernable on land, in freshwater, and coastal systems and these
are large in extent and long in duration. Thus, a natural laboratory exists.
(b) Florida is extremely susceptible to floods, droughts, hurricanes,
fires, and invasion of exotic species…all which combine with human impacts to put
great stress on ecosystems and challenge the ability for natural resources to be
maintained. Much of peninsula Florida will be threatened by rising sea level
and accompanying flooding of coastlines, salt water intrusion into water supplies
and destruction of habitat for wildlife. The state will be facing some unprecedented
challenges.
(c) For similar reasons, USF faculty are uniquely positioned to
address research issues in sustainability in the Gulf Coast states and the Caribbean
basin, a region entirely dependent on sustaining water resources and natural habitat
for economic well-being. Natural disasters directly impact the region each year.
USF faculty already actively engaged in research throughout this region; (e.g. modeling
the effects of water use patterns and sea-level rise on Mexican mangrove ecosystems;
computer simulation and visualization of volcanic and landslide hazards; water resource
management on carbonate islands). Such research in modeling complex interactions
between biological and physical environments, computer simulation, and visualization
is nationally and internationally recognized as crucial to development of scientific
bases for sustainability. No other university is better equipped to achieve long
term research success in sustainability in this geographic region than USF.
(d) Global changes in climate will have implications for the distribution
and health of plants and probably disease as temperature and rainfall patterns are
expected to be modified.
(e) Given the conditions outlined above, the natural laboratory
for conducting sustainable science sits in USF’s backyard. USF has other assets
that provide the infrastructure for innovative studies in global change sciences.
There is an already nationally known group of researchers who work on many of the
topics discussed above. Many of the technologies/ much of the instrumentation
to address research questions is already on campus. Excellent graduate students
in PhD programs have a long history of applying to USF’s programs to take advantage
of its natural laboratory and established graduate training.
