The overall objective of this study is to examine the interconnectivity of food, energy and water (FEW), as well as their interdependent dynamics following rapid changes in climate, population, economy and institutions that have intensified land use in Kazakhstan (KaZ) and Mongolia (MG). Our working hypothesis is that the interconnections and interdependencies of FEW measures vary significantly between KaZ and MG, among the regions within each country, and among herding landscapes. we challenged ourselves with three pressing questions: How have the FEW functions been affected by the independent and interactive forcings of biophysical and socioeconomic changes in water-limited KaZ and MG? What are the causes, regulatory mechanisms, and functional consequences of the FEW nexus at local, regional, and national levels? What are the roles of LCLUC in understanding the complex relationships between the causes and consequences of the FEW nexus at different spatial scales?
The Mongolian Plateau, divided by similar ecosystems yet contrasting socioeconomic systems known as Mongolia and Inner Mongolia, is home to rapid biophysical and socioeconomic changes. The purpose of this study is to bring together a multidisciplinary research team to examine and model the changes of the natural and human systems on the Plateau as well as the critical feedbacks between them over recent decades. This is the lab's third funded project investigating the Mongolian Plateau.
Land use, land cover changes, and ecosystem-specific management practices are increasingly recognized for their roles in mediating the climatic effects on ecosystem structure and function. As demonstrated by some scholars, human activities can influence C fluxes and storage far more than climatic changes. All of these activities require a CO2-equivalent amount of energy ("social C flux") to offset the actual amount of C sequestered by the ecosystems and landscapes. A complete life cycle assessment (LCA) is needed to account for the actual sequestration strength at different spatial and temporal scales.
Transitional economies in Southeast, East, and North Asia (SENA), including Cambodia, Laos PDR, Myanmar, Vietnam, China, Mongolia, and the Asian part of Russia (Siberia), have experienced liberalization, macroeconomic stabilization, restructuring and privatization, and legal and institutional reforms over the past three decades. Building upon our previous research, rich databases, and diverse expertise, we set our objective toward synthesizing the data and knowledge on urban sustainability to the socioeconomic transformation and changing climate in transitional economies in SENA.
Solar photovoltaic electricity technology is considered one of the top choices to meet the future's need for CO2-free sources. It must be made sustainable from economic, environmental, and societal perspectives. Our objective is to develop the concepts, materials, and processes necessary to economically produce environmentally friendly thin-film solar cells from earth-abundant, environmentally benign (EAEB) materials. We have assembled a multi-disciplinary team representing physics, materials science, engineering, chemistry, socioeconomics, environmental science, and education to address these complex issues.
The overall objective of this project is to synthesize our data, knowledge, and quantitative models on ecosystem and social resilience to the changing climate and dynamic socioeconomic pressures placed on the fragile, Mongolian ecosystems. This will be done by modeling natural system (NS) and human system (HS) processes and dynamics as well as the interactions and feedbacks among them. We will use multiple data sources to document human and natural dynamics at multiple temporal and spatial scales for the Plateau, where Inner Mongolia and Mongolia have had similar climates, ecosystems, cultures, and traditions, but different governments, land uses, economic development, and demographic changes in the past.
In this project, we use the eddy covariance (EC) method as our primary tool in making intensive, continuous measurements of NEP, water loss through evapotranspiration (ET) and energy balance at the six KBS-GLBRC “Scale-Up Fields”: switch grass, restored prairie and continuous corn fields (two replicates of each system).
We hypothesize that significant differences exist in ecosystem production, biophysical regulations and below-ground carbon allocation among the three biofuel production systems. These differences are clearly reflected at multiple temporal scales.
The USCCC mission is to facilitate better understanding of the environmental factors influencing the rate and magnitude of carbon sequestration and water cycling across a range of ecosystems and climates using mutually agreed upon measurement protocols and equipment, and through a collaborated network of data sharing and analysis.
