TLDR
In this paper, the authors examined how land-use trends affected net carbon fluxes in western Ukraine and assessed the region's future carbon sequestration potential using satellite-based forest disturbance and farmland abandonment rates from 1988 to 2007.Abstract:
Land use is a critical factor in the global carbon cycle, but land-use effects on carbon fluxes are poorly understood in many regions. One such region is Eastern Europe and the former Soviet Union, where land-use intensity decreased substantially after the collapse of socialism, and farmland abandonment and forest expansion have been widespread. Our goal was to examine how land-use trends affected net carbon fluxes in western Ukraine (57 000 km 2 ) and to assess the region’s future carbon sequestration potential. Using satellite-based forest disturbance and farmland abandonment rates from 1988 to 2007, historic forest resource statistics, and a carbon bookkeeping model, we reconstructed carbon fluxes from land use in the 20th century and assessed potential future carbon fluxes until 2100 for a range of forest expansion and logging scenarios. Our results suggested that the low-point in forest cover occurred in the 1920s. Forest expansion between 1930 and 1970 turned the region from a carbon source to a sink, despite intensive logging during socialism. The collapse of the Soviet Union created a vast, but currently largely untapped carbon sequestration potential (up to � 150 Tg C in our study region). Future forest expansion will likely maintain or even increase the region’s current sink strength of 1.48 Tg C yr � 1 . This may offer substantial opportunities for offsetting industrialread more

Making better use of accuracy data in land change studies: Estimating accuracy and area and quantifying uncertainty using stratified estimation
TL;DR: In this article, an error-adjusted estimator of area can be easily produced once an accuracy assessment has been performed and an error matrix constructed, which can then be incorporated into an uncertainty analysis for applications using land change area as an input (e.g., a carbon flux model).

Global Forest Transition: Prospects for an End to Deforestation
Patrick Meyfroidt,Eric F. Lambin +1 more
TL;DR: In this article, a review synthesizes existing knowledge on the occurrence, causes, and ecological impacts of forest transitions and examines the prospects and policy options for a global forest transition, concluding that the ecological quality of forest transition depends on multiple factors, including the importance of natural forest regeneration versus plantations.

TL;DR: In this paper, the authors discuss the use of principles from disturbance ecology and natural stand development to create silvicultural approaches that are more aligned with natural processes, including the role of disturbances in creating structural legacies that become key elements of the post-disturbance stands.

TL;DR: The results demonstrate that old-growth forests can continue to accumulate carbon, contrary to the long-standing view that they are carbon neutral, and suggest that 15 per cent of the global forest area, which is currently not considered when offsetting increasing atmospheric carbon dioxide concentrations, provides at least 10 per cent the global net ecosystem productivity.
