ABSTRACT Land degradation poses significant challenges to maintaining food–water–energy (FWE) security, particularly in rapidly urbanizing regions. The ecosystem services (ES) related to FWE are critical for sustainable regional development. Yet, rapid urbanization in the Beijing–Tianjin–Hebei region has altered land use and ecological patterns ...

The fate of currently frozen permafrost carbon as high-latitude climate warms remains highly uncertain and existing models give widely varying estimates of the permafrost carbon-climate feedback.

Peatland hydrology and carbon release: why small-scale process matters [PDF]
Peatlands cover over 400 million hectares of the Earth's surface and store between one-third and one-half of the world's soil carbon pool. The long-term ability of peatlands to absorb carbon dioxide from the atmosphere means that they play a major role ...

The influence of climate and hydrological variables on opposite anomaly in active-layer thickness between Eurasian and North American watersheds [PDF]
This study not only examined the spatiotemporal variations of active-layer thickness (ALT) in permafrost regions during 1948-2006 over the terrestrial Arctic regions experiencing climate changes, but also identified the associated drivers based on ...

Paleolimnology of thermokarst lakes: a window into permafrost landscape evolution
Widespread across northern permafrost landscapes, thermokarst ponds and lakes provide vital wildlife habitat and play a key role in biogeochemical processes. Stored in the sediments of these typically shallow and dynamic waterbodies are rich sources of paleoenvironmental information whose potential has not yet been fully exploited, likely because of ...

Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]
Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Modelling Rapid Changes in Ice-Rich Permafrost Landscapes
Ice-rich permafrost is estimated to underlie 20% of the Northern hemisphere’s permafrost region. It is particularly vulnerable to thawing processes referred to as “thermokarst”, which manifest in emerging characteristic landforms and rapidly changing landscapes.

North American Circum-Arctic Permafrost Degradation Observation Using Sentinel-1 InSAR Data
In the context of global warming, the accelerated degradation of circum-Arctic permafrost is releasing a significant amount of carbon. InSAR can indirectly reflect the degradation of permafrost by monitoring its deformation.
