Diverse interplay of grey and green space in distinct Asian arid and semi-arid cities
Thermal changes along the urban-rural continuums in Southeast Asia
Southeast Asia’s (SEA) rapid urbanization has intensified urban heat effects. While previous studies address urban warming at specific time points, the dynamic relationship between land cover and land use (LCLU) changes and land surface temperature (LST) along urban-rural continuums remains understudied. This study examines LST, LCLU, and NDVI changes across 19 SEA cities of varying urbanization levels from 2000 to 2022 using Landsat images. Resu…
Impact of Urban built-up volume on Urban environment
In this paper, the spatial patterns of urban form (e.g., 2D and 3D characteristics) from 2000 to 2020 in Jakarta are assessed and the interdependent relationships between urban built-up volume and urban environment are examined. Jakarta experienced rapid urban built-up land expansion of 19%, from 483 km2 in 2000 to 574 km2 in 2020 but with moderate urban built-up volumetric expansion at 4%, from 23.6 × 108 m3 in 2000 to 24.5 × 108 m3 in 2020. The…
Megagrazer loss drives complex landscape-scale biophysical cascades
Wild animals can modulate ecosystem-climate feedbacks, e.g. through impacts on vegetation and associated carbon dynamics. However, vegetation cover and composition also affect land surface albedo, which is an important component of the global energy budget. We currently know very little about the influence of wild animals on land surface albedo and the resulting climate forcing of these albedo changes. Leveraging a unique, ecosystem-scale, semi-e…
Rooting meta-ecosystems with reciprocal lateral carbon and nitrogen flows in a Yangtze coastal marsh
The dynamics of lateral nutrient fluxes through hydrological movements are crucial for understanding ecological functions related to the flow of energy, materials, and organisms across various spatiotemporal scales. To investigate the connectivity of multiple spatial flow processes, we conducted a one-year field study to measure lateral hydrologic carbon (C) and nitrogen (N) fluxes across the continental shelf in the Yangtze estuary. We observed …
Overlooked cooling effects of albedo in terrestrial ecosystems
Radiative forcing (RF) resulting from changes in surface albedo is increasingly recognized as a significant driver of global climate change but has not been adequately estimated, including by Intergovernmental Panel on Climate Change (IPCC) assessment reports, compared with other warming agents. Here, we first present the physical foundation for modeling albedo-induced RF and the consequent global warming impact (GWI Δ α ). We then highlight the …
Identifying opportunities for nature-based solutions with geospatialized life cycle assessments and fine-scale socioecological data
As we increasingly understand the impact that land management intensification has on local and global climate, the call for nature-based solutions (NbS) in agroecosystems has expanded. Moreover, the pressing need to determine when and where NbS should be used raises challenges to socioecological data integration as we overcome spatiotemporal resolutions. Natural and working lands is an effort promoting NbS, particularly emissions reduction and ca…
Albedo of crops as a nature-based climate solution to global warming
Surface albedo can affect the energy budget and subsequently cause localized warming or cooling of the climate. When we convert a substantial portion of lands to agriculture, land surface properties are consequently altered, including albedo. Through crop selection and management, one can increase crop albedo to obtain higher levels of localized cooling effects to mitigate global warming. Still, there is little understanding about how distinctive…
Grassland albedo as a nature-based climate prospect
Nature-based solutions for mitigating climate change focus largely on land management to reduce carbon emissions and enhance carbon sequestration. Tree planting, commonly advocated for carbon offset, threatens grassland biodiversity and may induce positive radiative forcing (warming) by lowering albedo. Before making decisions about land-use changes in grasslands, an understanding of the fine-scale albedo of grassy versus woody vegetation is need…
Global warming impacts of carbon dioxide, methane, and albedo in an island forest nature reserve
Forest ecosystems influence climate by sequestering carbon from the atmosphere and by altering the surface energy balance. However, the combined global warming impacts (GWIs), contribution from carbon dioxide (CO 2 ) fluxes, methane (CH 4 ) fluxes, and albedo changes (Δ α ) remain poorly understood. Here, we reported the combined GWIs of CO 2 , CH 4 , and albedo with eddy covariance (EC) measurements during 2020–2022 in a subtropical island fores…
Mapping the Future of Migration and Climate Change Science
The scholarship on migration and climate change has been rapidly developed over recent decades, moving away from apocalyptic predictions of mass displacement toward more nuanced modeling of the complex relationships between climate change and migration. Unfortunately, much of that development has happened in parallel to the core of migration studies and thus our prevailing migration theories do not reflect these emerging studies of climate and mi…
What caused the unseasonal extreme dust storm in Uzbekistan during November 2021
An unseasonal dust storm hit large parts of Central Asia on 4–5 November 2021, setting records for the column aerosol burden and fine particulate concentration in Tashkent, Uzbekistan. The dust event originated from an agropastoral region in southern Kazakhstan, where the soil erodibility was enhanced by a prolonged agricultural drought resulting from La Niña-related precipitation deficit and persistent high atmospheric evaporative demand. The du…
Diel, seasonal, and inter-annual variation in carbon dioxide effluxes from lakes and reservoirs
Accounting for temporal changes in carbon dioxide (CO 2 ) effluxes from freshwaters remains a challenge for global and regional carbon budgets. Here, we synthesize 171 site-months of flux measurements of CO 2 based on the eddy covariance method from 13 lakes and reservoirs in the Northern Hemisphere, and quantify dynamics at multiple temporal scales. We found pronounced sub-annual variability in CO 2 flux at all sites. By accounting for diel vari…
Untangling the impacts of socioeconomic and climatic changes on vegetation greenness and productivity in Kazakhstan
Studies examining the joint interactions and impacts of social-environmental system (SES) drivers on vegetation dynamics in Central Asia are scarce. We investigated seasonal trends and anomalies in drivers and their impacts on ecosystem structure and function (ESF). We explored the response of net primary production, evapotranspiration and normalized difference vegetation index (NDVI) to various SES drivers—climate, human influence, heat stress, …
Bound to Ulaanbaatar in Mongolia
During the urbanization process in Mongolia, Ulaanbaatar (UB) became the most dominant metro-city in the nation and the most popular migration destination. We examined the changes in migration to UB during the economic transition of 2002–2017 and explored driving forces using the dataset from the Mongolia National Labor Survey. The results confirmed that relatively higher wages and lower unemployment positively influenced migration toward UB. Usi…
Sustainability challenges for the social-environmental systems across the Asian Drylands Belt
This paper synthesizes the contemporary challenges for the sustainability of the social-environmental system (SES) across a geographically, environmentally, and geopolitically diverse region—the Asian Drylands Belt (ADB). This region includes 18 political entities, covering 10.3% of global land area and 30% of total global drylands. At the present time, the ADB is confronted with a unique set of environmental and socioeconomic changes including w…
Urban expansion inferenced by ecosystem production on the Qinghai-Tibet plateau
Assessments of changes in landscape patterns and functions during urban development need to factor urban fringes (UPs) as part of the overall social-environmental system, especially in regions with poor transportation systems where urban functions depend heavily on surrounding suburbs. In this study, we use net primary production (NPP) as an integrative measure to delineate UPs and to measure the expansion in 15 urban areas in the remote Qinghai-…
Albedo-induced global warming impact of Conservation Reserve Program grasslands converted to annual and perennial bioenergy crops
Climate benefit assessments of bioenergy crops often focus on biogeochemical impacts, paying little if any attention to biogeophysical impacts. However, land conversions required for large-scale bioenergy crop production are substantial and may directly affect the climate by altering surface energy balance. In the US, such land conversions are likely to be met in part by converting Conservation Reserve Program (CRP) grassland to bioenergy crops. …

The biophysical climate mitigation potential of boreal peatlands during the growing season
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the bioph…
Non-climatic component provoked substantial spatiotemporal changes of carbon and water use efficiency on the Mongolian Plateau
Understanding the joint impact of anthropologic and climatic changes on ecosystem function and dynamics is among the frontiers in global environmental change studies. Carbon and water balances are especially crucial to the sustainable ecosystem and functional returns in sensitive regions such as the Mongolian Plateau. In this study, the significance of non-climatic component (NCC) on carbon and water use efficiency (CUE and WUE) is quantified amo…
Carbon debt of field-scale conservation reserve program grasslands converted to annual and perennial bioenergy crops
Over 5 million ha of US Conservation Reserve Program (CRP) grasslands have been converted to annual crops since 2000, driven mainly by demand for corn grain ethanol. Much of the soil carbon sequestered under CRP is lost upon conversion, creating a 'carbon debt' that is presumed to be repaid by future greenhouse gas (GHG) savings from ethanol's substitution for petroleum. Model simulations, extrapolations, and national statistics rather than direc…
Livestock dynamics under changing economy and climate in Mongolia
Nature-based solutions for resilient landscapes and cities
Dryland belt of Northern Eurasia
The dryland belt (DLB) in Northern Eurasia is the largest contiguous dryland on Earth. During the last century, changes here have included land use change (e.g. expansion of croplands and cities), resource extraction (e.g. coal, ores, oil, and gas), rapid institutional shifts (e.g. collapse of the Soviet Union), climatic changes, and natural disturbances (e.g. wildfires, floods, and dust storms). These factors intertwine, overlap, and sometimes m…
Incorporating Culture Into Sustainable Development
Integrating culture into sustainable development (SD) has been an ongoing research topic, but has not yet been of interest to the green building community. Existing green building programs, including standards, certification and auditing schemes, focus on technical assessment. By assuming that a building is a cultural resource, which reflects the past and shapes the future of a society, we added cultural sustainability for green buildings by reco…

Climate change in Inner Mongolia from 1955 to 2005—trends at regional, biome and local scales
This study investigated the climate change in Inner Mongolia based on 51 meteorological stations from 1955 to 2005. The climate data was analyzed at the regional, biome (i.e. forest, grassland and desert) and station scales, with the biome scale as our primary focus. The climate records showed trends of warmer and drier conditions in the region. The annual daily mean, maximum and minimum temperature increased whereas the diurnal temperature range…
Land cover/land use change in semi-arid Inner Mongolia
The semi-arid grasslands in Inner Mongolia (IM) are under increasing stress owing to climate change and rapid socio-economic development in the recent past. We investigated changes in land cover/land use and landscape structure between 1992 and 2004 through the analysis of AVHRR and MODIS derived land cover data. The scale of analysis included the regional level (i.e. the whole of IM) as well as the level of the dominant biomes (i.e. the grasslan…
Recent decline in the global land evapotranspiration trend due to limited moisture supply
Climate control of terrestrial carbon exchange across biomes and continents
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems \nis critical to predict future levels of atmospheric carbon dioxide because of the potential \naccelerating effects of positive climate–carbon cycle feedbacks. However, directly observed \nrelationships between climate and terrestrial CO2 exchange with the atmosphere across biomes \nand continents are lacking. Here we present data describing the relatio…
Comparing patterns of ecosystem service consumption and perceptions of range management between ethnic herders in Inner Mongolia and Mongolia
Ecosystems in the Central Asian Plateau, which includes the Mongolian Plateau, are becoming increasingly sensitive to human interventions, leading to deterioration of already fragile ecosystems. The goal of this paper is to illustrate human dependence on an ecosystem by identifying patterns of resource consumption in this region and investigating the knowledge and perceptions of herders living in these ecosystems. Data on consumption in the two r…
Understanding the coupled natural and human systems in Dryland East Asia
Stressors including regional climate change, economic development effects upon land use and an increasing demand for food production have resulted in significant impacts on the dryland ecosystems in the East Asia (DEA) region. Ecosystem services, such as its provisional services in providing forage for grazing as well as its functional services in regulating water and carbon fluxes, have been significantly altered over the past three decades. Con…

Vegetation response to extreme climate events on the Mongolian Plateau from 2000 to 2010
Climate change has led to more frequent extreme winters (aka, dzud) and summer droughts on the Mongolian Plateau during the last decade. Among these events, the 2000–2002 combined summer drought– dzud and 2010 dzud were the most severe on vegetation. We examined the vegetation response to these extremes through the past decade across the Mongolian Plateau as compared to decadal means. We first assessed the severity and extent of drought using the…
Grazing alters the biophysical regulation of carbon fluxes in a desert steppe
To determine the role of grazing on CO2 fluxes in a desert steppe, we used paired eddy-covariance systems to measure the net ecosystem exchange (NEE) and microclimate on adjacent pastures of grazed (GS) and ungrazed (FS) steppes on the Mongolian Plateau from 2010 to 2011. The first year was an average precipitation year, while the second year was a dry year. In 2010, there was 91% greater growing seasonal gross ecosystem production (GEP) and 55% …
Policy shifts influence the functional changes of the CNH systems on the Mongolian plateau
By applying the concept of the coupled natural and human system (CNH), we compared spatiotemporal changes in livestock (LSK), land cover, and ecosystem production to understand the relative roles that natural and social driving forces have on CNH dynamics on the Mongolia plateau. We used socioeconomic and physical data at prefecture level for Inner Mongolia and Mongolia from 1981 through 2010 to represent changes in net primary productivity (NPP)…

Agent‐Based Modeling of Temporal and Spatial Dynamics in Life Cycle Sustainability Assessment
Current aggregate and top‐down approaches in life cycle sustainability assessment (LCSA) generally fail to account for spatial, temporal, and emergent behavioral dynamics simultaneously during the inventory stage. We discuss the key characteristics captured by complex system approaches (agent‐based modeling [ABM] in particular) in the context of LCSA. It is understood that by integrating ABM, temporal, spatial, and behavioral dynamics can be addr…

Quantifying the effect of forest age in annual net forest carbon balance
Forests dominate carbon (C) exchanges between the terrestrial biosphere and the atmosphere on land. In the long term, the net carbon flux between forests and the atmosphere has been significantly impacted by changes in forest cover area and structure due to ecological disturbances and management activities. Current empirical approaches for estimating net ecosystem productivity (NEP) rarely consider forest age as a predictor, which represents vari…
Urbanization and sustainability under transitional economies
Spanning a vast territory of approximately 13 million km ^2 , Asian Russia was home to 38 million people in 2016. In an effort to synthesize data and knowledge regarding urbanization and sustainable development in Asian Russia in the context of socioeconomic transformation following the breakup of the Soviet Union in 1990, we quantified the spatiotemporal changes of urban dynamics using satellite imagery and explored the interrelationships betwee…
Prospects for the sustainability of social-ecological systems (SES) on the Mongolian plateau
The Mongolian Plateau hosts two different governments: the Mongolian People's Republic and the Inner Mongolia Autonomous Region, a provincial-level government of the People's Republic of China. The divergence between these governments has widened in the past century, mostly due to a series of institutional changes that generated different socioeconomic and demographic trajectories. Due to its high latitude and altitude, the Plateau has been highl…

Spatiotemporal Changes in PM2.5 and Their Relationships with Land-Use and People in Hangzhou
Increases in the extent and level of air pollution in Chinese cities have become a major concern of the public and burden on the government. While ample literature has focused on the status, changes and causes of air pollution (particularly on PM 2.5 and PM 10 ), significantly less is known on their effects on people. In this study we used Hangzhou, China, as our testbed to assess the direct impact of PM 2.5 on youth populations that are more vul…
