My overarching research goal is to develop and interpret high-resolution paleoclimatic records in order to further our understanding of past natural and recent anthropogenic climate change over the past 2000 years. Three main themes have driven my work throughout my academic and research career:
1. Understanding climate change on long-term scales and the climate impacts on the landscape and people.
2. Building interdisciplinary research partnerships to apply new approaches to environmental problems.
3. Working with students, teachers, public audiences and artists to communicate the excitement of scientific explorations and the significance of the results.
My dissertation research focused on creating a high-resolution network of drought sensitive tree-ring chronologies across Mongolia to develop a deeper understanding of natural variability of droughts and pluvials, including duration, extremes and frequency of events over the past 400 to 500 years (Davi et al. 2006, 2010, 2012a, Davi 2010).
Mongolia is a pristine country with roughly half its people practicing a traditional nomadic herding existence. Their livelihoods and well-being are inextricably connected to the health of their livestock and the productivity of the country’s grasslands. As such, they are extremely vulnerable to climate variability and change. A multi-decadal drought, which began in 1999, has depleted grasslands and has contributed to massive livestock death as well as great economic hardship and poverty. My research focused on understanding the stability of Mongolian water resources through time, and shedding light on climate cycles, extremes and spatial patterns.
My current research integrates the Mongolian paleoclimatic data with both atmospheric dynamics and remote sensing, in order to evaluate the climate forcing behind multi-decadal droughts and to quantify the impacts of climate change on ecosystems and people.
