    Increases in the abundance of woody species have been reported to affect the provisioning of ecosystem services in drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, and fire, interact to determine woody dominance across global drylands. We conducted a standardized field survey in 304 plots across 25 countries to assess how climatic features, soil properties, grazing, and fire affect woody dominance in dryland rangelands. Precipitation, temperature, and grazing were key determinants of tree and shrub dominance. The effects of grazing were determined not solely by grazing pressure but also by the dominant livestock species. Interactions between soil, climate, and grazing and differences in responses to these factors between trees and shrubs were key to understanding changes in woody dominance. Our findings suggest that projected changes in climate and grazing pressure may increase woody dominance in drylands, altering their structure and functioning.

    Geophysical evidence for Holocene lake-level change in southern California (Dry Lake)
    (Wiley, 2010) Bird, Broxton W.; Kirby, Matthew E.; Howat, Ian M.; Tulaczyk, Slawek; Earth Sciences, School of Science
    Ground penetrating radar (GPR) data are used in combination with previously published sediment cores to develop a Holocene history of basin sedimentation in a small, alpine lake in southern California (Dry Lake). The GPR data identify three depositional sequences spanning the past 9000 calendar years before present (cal. yr BP). Sequence I represents the first phase of an early Holocene highstand. A regression between <8320 and >8120 cal. yr BP separates Sequence I from Sequence II, perhaps associated with the 8200 cal. yr BP cold event. Sequence II represents the second phase of the early-to-mid Holocene highstand. Sequence IIIa represents a permanent shift to predominantly low lake stands beginning ∼5550 cal. yr BP. This mid-Holocene shift was accompanied by a dramatic decrease in sedimentation rate as well as a contraction of the basin's area of sedimentation. By ∼1860 cal. yr BP (Sequence IIIb), the lake was restricted to the modern, central basin. Taken together, the GPR and core data indicate a wet early Holocene followed by a long-term Holocene drying trend. The similarity in ages of the early Holocene highstand across the greater southern California region suggests a common external forcing – perhaps modulation of early Holocene storm activity by insolation. However, regional lake level records are less congruous following the initial early Holocene highstand, which may indicate a change in the spatial domain of climate forcing(s) throughout the Holocene in western North America.

    Health Impact Assessment: The Impacts of Increasing Tree Canopy Coverage in Marion County, Indiana
    (Society of Practitioners of Health Impact Assessment, 2022) Kampman, Haleigh; Whitlock, Annika; Hosler, Heidi; Health Policy and Management, Richard M. Fairbanks School of Public Health
    Background: Urban tree canopies help to address issues of climate change related to all dimensions of health. Certain areas of the city of Indianapolis are more prone to the negative effects that lack of tree coverage can cause. This assessment explored the short term and potential long-term impacts of the efforts to increase the tree canopy coverage in vulnerable areas of Indianapolis. This effort was a collaboration of faculty members from the Indiana University Richard M. Fairbanks School of Public Health, Indianapolis Department of Public Works, Keep Indianapolis Beautiful, and the Indianapolis Office of Sustainability. Methods: Our team used the standard seven-step Health Impact Assessment (HIA) process to make the recommendations provided. Using direct observation of the neighborhood, secondary data collection, literature review, and a key stakeholder interview, we examined key dimensions of health including environmental, physical, and personal health outcomes resulting from increased tree canopy coverage within census tract 3505 of Marion County, Indiana. Results: Increasing the percentage of tree canopy coverage in census tract 3505 – Crown Hill has significant positive health impacts with minimal negative outcomes. Such impacts may be, but are not subject to, lower temperatures, reduced cases of respiratory and cardiac infections/illnesses, promoting animal life, increasing neighborhood property values and filtering pollutants that result from human production activity. Conclusions: Further implementation of the Thrive Indianapolis project has broad positive implications for the community members living in this area. While few negative implications were found, we make recommendations to mitigate these effects while attempting to supplement the current project plan with a focus on the effects to human health.

    Our Hot Future Has Arrived—Are We Prepared?
    (Wiley, 2023-09-20) Filippelli, Gabriel M.; Earth and Environmental Sciences, School of Science
    Climate change has significantly enhanced dangerous heat events. Many of our institutions are ill‐prepared to provide science‐informed and rapid interventions to confront this. The GeoHealth community is working to bring science, public health, and medical professionals closer together to grapple with the challenges posed by extreme heat.

    Sky View Factor Measurements in Support of Local Climate Zone Classification
    (Indiana View, 2020) Adhikari, Bikalpa; Wilson, Jeffrey S.; Geography, School of Liberal Arts
    Increasing urbanization coupled with threats from global climate change are driving research innovations that seek to inform sustainability of urban socio-ecological systems. The Local Climate Zone (LCZ) classification system developed by Stewart and Oke (2012) provides a framework for examining relationships between urban morphology and temperature, as well as a standardized approach to facilitate data integration from around the globe. In addition to urban heat island studies, parameters used to define LCZs are increasingly applied in related fields, such as modeling fine-scale variations in urban air quality (Badach et al., 2020).
