4. About the Lab

Laboratory of Macroecology & Global Change
Zhenzhong Zeng, Ph. D.

“We follow our curiosities, focus on our environment, and target at developing a scientific understanding of Earth as a system.”

Zeng’s research focuses on biosphere-atmosphere interactions and global environment change. His long-term goal is to develop a more mechanistic and predictive ecological climatology. This is very important given that the human-dominated Earth has deviated from her equilibrium state and we all are at risk that self-reinforcing feedbacks of the Earth may push the planet to extreme states (e.g. Hothouse Earth). Among the feedbacks, the biogeophysical feedback within the Earth System coupled with direct human influences of the biosphere are the key. To achieve this long-germ goal, we need to increase observations for quantification of human impacts on the biosphere, and to advance our understanding on the feedbacks of biosphere change to water cycle and climate system. Zeng has long worked on understanding and modelling the role of vegetation in the terrestrial water cycle and the global climate system, determining the response of the biosphere to human impacts, and quantifying how the biosphere response feeds back to the water cycle and climate system. His research draws heavily upon transdisciplinary inference, process-based approaches, and data-driven machine learning to develop mechanistic and predictive ecological climatological models. His background gives him a unique perspective for addressing questions about the biosphere-atmosphere interactions, and their implications to global environmental change.

Zeng is currently working on observations, drivers, impacts, and solutions of agricultural expansion and forest loss in the tropical regions. Other interests include water resources, climate mitigation, and engineering application.

Previous and current research. Zeng’s research has always focused on the changes in biosphere and atmosphere, and their interactions. As for the biosphere change, currently he is particularly interested in the land use changes in Southeast Asia, the region with the highest rate of forest loss recently (a). His graduate research also focused on the biosphere change in response to the climate change (b). His investigation on the climate impacts of vegetation change has fully addressed the biophysical climate impacts of Earth’s greening (c). In addition, his research also touch the atmosphere change, in particular the characterization of global climate change and diagnosis of global climate models (d).
a) Rapid agricultural expansion and forest loss in the Southeast Asia Massif in the 21st century. Using the latest and most accurate datasets available for identifying forest change, Zeng found that farmers are carving a new agricultural frontier from the highland forests of Mainland Southeast Asia (Myanmar, Thailand, Laos, Vietnam, Cambodia), which has been missed by existing global land use, and forest loss analyses. Between 2000 and 2014, farmers converted 8.2 million hectares of highlands. This highland conversion stands in sharp contrast to Latin America and China, where highland agriculture has been retreating and forests regenerating. The finding is of importance because of carbon effects and because highland forests represent one of the last redoubts for this region’s remarkable diversity. It also calls into question broadly used projections by the UN Food and Agriculture Organization that the area will experience little to no future, net agricultural expansion. By highlighting this omission, his finding may help to rectify this error in time for the IPCC’s 6th Assessment Report, while spurring further research into the climatic impacts of agriculturally driven highland deforestation (Zeng et al., 2018a,b NGO, GCB).
b) Changes of terrestrial vegetation under the changing climate. Zeng has produced a substantial body of research on how global environmental changes are rapidly altering terrestrial vegetation dynamics. To begin, he observed the climate space of tropical trees to determine tree cover equilibrium. He found that tropical forests regress of disappear in transition zones, resulting in major ecological shifts and biodiversity loss. Using a machine learning algorithm called boosted regression trees, Zeng calculated tropical forest and savanna distributions in the context of global climate change. He estimated that approximately one-third of tropical forests will be lost to savanna by the late twenty-first century, an alarming future scenario. Furthermore, he worked with his colleagues to utilize satellite leaf area index records and global ecosystem models to determine the drivers of long-term satellite leaf area trends from 1982 to 2009. They discovered a trend of widespread and rising greening, which they attributed to carbon dioxide fertilization effects, nitrogen deposition, climate change, and land cover changes (e.g. Zeng et al., 2013 Scientific Report, 2014 JGR-Biogeosciences; Zhu et al., 2017 NCC).
c) Investigation on the climate impacts of vegetation change. This research began with the analysis of large-scale afforestation in China. In addition to confirming the fact that afforestation has a significant impact on land surface temperature and evapotranspiration, they also discovered that increased vegetation activity attenuates daytime warming in climate simulations and statistical analyses. Taking this work even further, Zeng studied how the climate system has been affected by the Earth greening using satellite monitoring techniques and global climate models. Zeng discovered that global greening has slowed the rise of global land-surface temperature due to increased evapotranspiration, altered atmospheric circulation, decreased shortwave transmissivity, increased longwave air emissivity warming, and decreased albedo. Zeng also found that the effects of large-scale atmospheric circulation changes have masked the significant relationship between vegetation greening and surface temperature in eastern North America and East Asia. In total, Zeng discovered that greening biophysical feedback mitigates about twelve percent of global-land surface warming (e.g. Peng et al., 2014 PNAS; Shen et al., 2015 PNAS; Zeng et al., 2016 ERL, 2017 NCC, 2018c,d,e JCli, ERL, Current Opinion in Environmental Sustainability).
d) Characterization of the global climate change and diagnosis of global climate models. In this field, Zeng has produced important research on the warming-elevation relationship using records from thousands of meteorological stations around the globe. Whereas he discovered that global warming occurs faster at higher altitudes in Asia and western North America, he found that Central Europe and eastern North America exhibit the opposite trend. Zeng discovered that differences in air pollution account for this variation and thus modulate warming-elevation relationships. In addition, Zeng worked with his colleagues to quantify the spatiotemporal variations between satellite and land station-based surface temperature calculations, climatological temperature lapse rates, and regional patterns of runoff changes. They also adjusted dynamic global vegetation models and earth system models to account for land surface albedo biases. Finally, they quantified China’s total greenhouse gas emissions to determine the overall impact that the nation has on total climate change (e.g. Zeng et al., 2015 GRL; Li et al., 2016 JGR-Atmospheres; Lian et al., 2016 JGR-Atmospheres; Li et al., 2016 Nature).

Future research. Zeng will continue his research in these fields (i.e. the biosphere-atmosphere interactions and global environment change) and work with the group members to address the Earth system, via leveraging existing collaborations, datasets and models, as well as building new collaborations with scientists all around the world.

As mentioned at the beginning, the Focus Areas include:
• Climate Variability and Change
• Attribution, Impact and Mitigation of Climate Change
• Biosphere-Atmosphere Interaction
• Circulation and Teleconnection
• Land Cover and Land Use Change
• Nexus of Water, Energy and Carbon Cycles
• Terrestrial Ecology and Hydrology
