Deborah Lawrence, Ph.D., is a Professor of Environmental Sciences at the University of Virginia. Her research focuses on the links between tropical deforestation and climate change. She has spent the past twenty-five years doing field-based research in Indonesia, Costa Rica, Mexico and Cameroon. Most recently, she has been using global climate models to explore the cumulative effect of tropical land use decisions, exploring the climate impact of land allocation among food crops, biofuels and forests across the globe. Professor Lawrence and her students conduct interdisciplinary research with partners in hydrology, atmospheric science, economics, anthropology, ethics, engineering, and law to understand the drivers and consequences of land use change. This work has gained her a Sustainability Science Award from the Ecological Society of America, a Guggenheim Fellowship, a Jefferson Science Fellowship from the National Academy of Sciences, and a Fulbright Scholarship. She was a post-doctoral fellow at Harvard University, earned her Ph.D. (Botany) at Duke University, and received a B.A. (Biological Anthropology) from Harvard University. Current research addresses the challenge of understanding and minimizing climate impacts from forest use in the tropics and around the globe.

In 2009-2010, Professor Lawrence served as Science Advisor in the Office of Environment and Global Change and the Office of the Special Envoy for Climate Change at the US Department of State. Focusing on tropical forests and climate change, she participated in the international negotiations of the United Nations Framework Convention on Climate Change (UNFCCC), supported the US delegation to the World Bank Forest Carbon Partnership Facility and Forest Investment Program, and was part of several inter-agency missions on reducing emissions from deforestation and degradation (REDD+) in Indonesia and Southeast Asia. She also served as the point of contact for the Group on Earth Observations (GEO) with a focus on the Forest Carbon Task. She worked with State, US Agency for International Development, US Forest Service and Department of the Treasury on issues regarding the Tropical Forest Conservation Act, mission program development for the sustainable landscapes program, and congressional issues relating to tropical forests.

Since 2010, Professor Lawrence has been consulting with the International Programs Office of the US Forest Service and the Climate Change Office of USAID on scientific and technical aspects of forest carbon measurement and monitoring under SilvaCarbon, the US contribution to the Global Forest Observation Initiative under GEO. In 2011, she was a visiting scientist at the Center for International Forestry Research (CIFOR) in Bogor, Indonesia where she worked on minimizing the climate impacts of oil palm expansion with partners at World Resources Institute, Sekala Indonesia, and the Climate and Land Use Alliance.

UVA’s Deborah Lawrence On Food, Fuels and Forests

Environmental scientist Deborah Lawrence leads a multidisciplinary group of University of Virginia faculty members delving into the issues involving forecasts of land use, energy and the environment in 2050.

In Our Bones: A New Understanding for Climate Change | Deborah Lawrence | TEDxCharlottesville

Deborah Lawrence, a biogeochemist and tropical ecosystem ecologist, was banished from a remote village of Borneo after 6 years of research there on the tropical rainforest as a graduate student. The lessons learned, her failure to effectively make her work understood to the villagers, she now applies to how we as a people can address our own village, the planet earth, and positively affect our environment.

Stephanie Roe (Profile) Stephanie is a land use scientist with a BA from San Diego State University and a MEM from Duke University. She has over seven years of experience working for governments, NGOs, the private sector and academia on research, policy design and field implementation of interventions that address climate change, ecosystem conservation, development and food security. Originally from the Philippines, Stephanie has worked and lived in DC, New York, Brazil, Mexico, Indonesia, Argentina, and Costa Rica. She is interested in the food, fuel, and forest dynamic, and how to shift the current land-use paradigm to a more sustainable system. Her doctoral work at UVA involves modeling the impact of agriculture, bioenergy and forest policies being employed in the tropics, and how they may alter the earth system - including climate change, soil and water provision and biodiversity. Currently, she is exploring the effects of livestock and crop intensification practices on climate and the supply of food through 2050. Christiane Runyan Christiane Runyan attended the University of Wyoming, where she competed on their college rodeo team. After graduation, she worked for EarthPeople, a sustainable consulting firm, and the Baltimore Ecosystem Study LTER. Christiane received an M.S. in Environmental Science in 2008 from Johns Hopkins University in 2006. Prior to starting at UVA, she worked for the Center for Urban Environmental Research and Education where she examined the scale and quality of data required to simulate hydrological processes in an urban watershed using a rainfall-runoff model and analyzed diurnal fluctuations in shallow groundwater data attributable to evapotranspiration. Currently, her dissertation research focuses on how deforestation affects the dynamics of hydrological and biogeochemical processes. Specifically, her research examines cases where deforestation alters the conditions necessary for forest regeneration and where such changes in land use can cause abrupt shifts from a fully vegetated state to a bare state with limited vegetation. She was awarded a Presidential Fellowship from the University, and is working with Lawrence and Paolo D’Odorico in the southern Yucatan. Rishiraj Das, Ph.D. 2012. Rishi is a Scientist at Conservation International, working on a USAID-funded project called Forest Carbon Markets and Communities. He came to UVa with a Masters from the Yale School of Forestry and Environmental Studies. He conducted his research as part of a collaboration between the Lawrence lab, Birgit Schmook at ECOSUR (in Mexico) and Paolo D’Odorico’s lab at the University of Virginia. The project was to test whether deforestation and subsequent land use can alter the small, but critical inputs of phosphorus deposited onto the tree canopy by altering the structure of the forest. In southern Mexico, he compared throughfall and stemflow phosphorus inputs in mature and secondary forest, linking temporal patterns with changing sources of airborne particles including dust and products of biomass burning. Using remotely sensed data and models, he also bracketed the amount of P derived from African dust. P inputs are significantly enhanced due to canopy trapping by the leaves, stems and branches of the forest. The P added is about 20-30% of the amount needed to support a mature forest canopy. Rishi was a Jefferson Fellow of the University of Virginia. He also received a Dissertation Year Fellowship, and the Vice President’s Graduate Research Award for Outstanding Doctoral Candidates. Kate Tully, Ph.D. 2011, M.S. 2007. Currently a post-doctoral fellow at the Earth Institute of Columbia University, Kate turned down a Fulbright Scholarship in India to work on the Millennium Villages Project in Africa. Her Master’s research investigated the litter nutrient dynamics of secondary forests in Costa Rica. This work showed a surprising decline in leaf litter nitrogen with increasing nighttime temperatures over a seven-year period. For her PhD, Katie investigated whether organic management altered nutrient retention and loss in the coffee agroforestry systems of Costa Rica. Employing ecological and hydrological methods, as well as survey techniques from the social sciences, she concluded that the density of trees was more important than the type of fertilizer management. Kate was a Jefferson Fellow, and she received a Dissertation Year Fellowship, a Bankard Fellowship, Raven Fellowship, and Double Hoo Research Award from the university. She also received an Exploratory Award from the Environmental Sciences department. Karen Vandecar, Ph.D. 2010. Karen is coordinating a project on climate change curriculum development for the US Forest Service as part of a larger USAID project called Lowering Emissions from Asian Forests (LEAF). She conducted research under the CICLOS project, a collaboration between the Lawrence lab and Steve Oberbauer (FIU), Deborah Clark (UMissouri), Anne Russell (ISU), David Genereux (NCSU), Terry McGlynn (SDSU), Nora Bynum (OTS), Luitgaard Schwendemann (then at University of Goettingen), and Javier Espeleta (OTS). She studied the controls on spatial and temporal variation in soil nutrients across a soil fertility gradient in mature forests of La Selva Biological Station in Costa Rica. She worked at time scales from hours to years and spatial scales from 10s to 1000s of meters. She published the first study ever to demonstrate a strong link between plant phosphorus demand (driven by photosynthesis) and soil phosphorus availability over the course of a day. She received the Environmental Sciences Publication Award, a Robert J. Huskey Travel Fellowship, and an Environmental Sciences Exploratory Award. Marcia DeLonge, M.S. 2007 Marcia worked with the Lawrence Lab while getting her MS at the University of Virginia from 2004-2007. In collaboration with Paolo D’Odorico, she investigated hydrological controls on phosphorus cycling in the dry tropical forests of the Yucatan Peninsula, Mexico. This project used a combination of field work (throughfall and leachate experiments), lab work (P mineralization and bioavailability studies), and modeling to identify important feedbacks between these forests and nutrient cycling. Following her MS, Marcia remained at UVa to pursue a doctoral degree emphasizing the influence of surface processes on the development of storms over the coast of West Africa. Marcia was a Presidential fellow at UVa, and she also won the Fred Holmsely Moore Research Award, Hydrology Graduate Award, and an Environmental Science Exploratory Research Award. Upon graduation, she received an NCAR Advanced Studies Program Visitor Award, which she took to work in Whendee Silver’s Lab at the University of California Berkeley, researching land management techniques for grasslands and associated strategies for greenhouse gas emission mitigation. Tana Wood, Ph.D. 2006, M.S. 2002 Tana is Adjunct Scientist at the International Institute of Tropical Forestry (IITF) of the USDA Forest Service. Tana worked on the Bosques Project, a collaboration between the Lawrence lab and Robin Chazdon’s lab at the University of Connecticut. She compared soil and litter nutrient dynamics in mature and secondary forests at La Selva Biological Station in Costa Rica, investigating the effects of tree species composition, soils, and topography. She conducted the first large-scale litter manipulation experiment ever, raking the equivalent of one football field, moving hundreds of kilograms of forest floor litter. Of the snakes she encountered, she says, “I am not sure exactly how many snakes. We saw lots of Fer de lance and Hog nose vipers. A coral snake... The biggest surprise was the number of bushmasters. I believe we encountered four, which is a lot... they are considered rare.” While at UVa, Tana won four research awards from the Department of Environmental Sciences and a Dissertation Year Fellowship from the University. Upon graduating, Tana won a NOAA Climate and Global Change Postdoctoral Fellowship, which she took to the University of California, Berkeley. Lucy Diekmann, M.S. 2004. Lucy was a Jefferson Fellow at the University of Virginia. While in the Lawrence lab, she worked on the SYPR project, a study of the causes and consequences of land use change in the Southern Yucatan Peninsula Region. The project was a collaboration between the Lawrence lab and Billie Turner in the geography department at Clark University, David Foster at Harvard Forest, and Hans Vester, at El Colegio de la Frontera Sur in Quintana Roo, Mexico. She studied changes, over multiple cycles of shifting cultivation, in the spatial distribution of nutrients and the distribution of phosphorus among physic-chemical pools of varying biological availability. After leaving the University of Virginia, Lucy went on to pursue a PhD at the University of California, Berkeley. James Eaton, M.S. 2003 Jamie is a Senior Manager for Forestry and Technical Services at TerraCarbon LLC, where he develops projects related to forest carbon sequestration. Prior to this, Jamie worked as a Science Policy Analyst at The Terrestrial Carbon Group, focusing on issues related to reducing emissions from deforestation and forest degradation (REDD, now REDD+). His research, part of the SYPR project on the causes and consequences of deforestation with Clark University, Harvard Forest, and El Colegio de la Frontera Sur, focused on how carbon accumulation in biomass and soils varies as a function of the number of prior cycles of shifting cultivation. He also conducted a study on the stocks and decomposition of coarse woody debris. Keya Chatterjee, M.S. 2002 Keya Chatterjee is a Senior Director in the climate change program at the World Wildlife Fund (WWF) in the US. She is also author of the book The Zero Footprint Baby: How to Save the Planet While Raising a Healthy Baby.

Research: 
Professor Deborah Lawrence, an ecosystem ecologist and biogeochemist, conducts conservation-oriented research in tropical forests in collaboration with scientists from the disciplines of hydrology, geography, economics and anthropology. Her current research addresses the challenge of understanding and minimizing climate impacts from forest use in the tropics, considering local scale ecological effects, landscape to regional phenomena, and impacts on the global carbon cycle and the climate system. Her work involves both the scientific issues and the policy constraints involved in reducing greenhouse gas emissions from deforestation and forest degradation (REDD+). For over a decade, Professor Lawrence worked in northeastern Costa Rica, where reforestation is now replacing deforestation. Before that, she also worked for a decade in the rainforests of Indonesian Borneo, a fast-moving deforestation frontier. She received her first Fulbright scholarship for research in Cameroon in 1989 and received a second one for Thailand in 2009. She currently works in southern Mexico, a global hotspot of deforestation. Her research focuses on how nutrient cycling is affected by tropical deforestation and subsequent changes in land-use. With a Guggenheim fellowship, she returned to Indonesia in 2011 to study the constraints on sustainable oil palm expansion and the consequences of a business-as-usual approach to an agribusiness industry that is viewed as a potential engine of rural economic development. In the Yucatan, Deborah Lawrence has worked since 1998 with an interdisciplinary team including geographers, economists, remote sensing scientists, anthropologists and hydrologists, as well as ecologists. The team approaches the tropical landscape as a coupled system with feedbacks between human decision-making and dynamics of the physical and biological systems they inhabit. She and her graduate students and collaborators study how human management affects the flow of nutrients, energy, carbon, and water in the dry forests of the region. They consider the dual stressors of human land use and water stress, and they consider scales from a single tree to a farmer’s parcel; from the entire peninsula to the span of the atmosphere connecting southern Africa to the Americas. Lawrence has also studied interactions between forest structure (anthropogenic alteration as well as natural variation), climatic variation, and nutrient cycling with an interdisciplinary group of scientists at La Selva Biological Station in Costa Rica. From 1999 to 2010, she investigated how tree species, forest age, and soil fertility influence the response of tree productivity, nutrient use efficiency, and soil nutrient dynamics to changes in rainfall, temperature, and solar radiation. This research grew out of Lawrence’s earlier work (1987-1997) in West Kalimantan, Indonesia, where she reconstructed land use histories to study the intersection of changes in tree diversity, landscape structure, and soil nutrients during 200 years of shifting cultivation. At the time, shifting cultivation (also known as slash-and-burn) was a significant driver of deforestation around the world. The drivers of deforestation have changed—to large-scale, industrial actors—and the focus of Lawrence’s research has shifted accordingly. The ultimate goal of Professor Lawrence’s work is to improve understanding of how human land use alters the functioning and resilience of tropical forest ecosystems in the face of a changing climate. In her work, she strives to illuminate the consequences of forest conversion, management, and degradation for human well-being, local to regional scale ecosystem processes and the global climate system.
