Humans have substantially modified the Earth's land cover, especially by transforming natural ecosystems to agricultural areas. In preindustrial times, the expansion of agriculture was probably the dominant process by which humankind altered the Earth system, but little is known about its extent, timing, and spatial pattern. This study presents an approach to reconstruct spatially explicit changes in global agricultural areas (cropland and pasture) and the resulting changes in land cover over… 
Spatiotemporal reconstruction of agricultural land cover in Nepal from 1970 to 2010
Agricultural land cover and changes in its extent are directly related to human activities. The rapidly growing population in Nepal has resulted in an increasing trend of agricultural land expansion,
Spatiotemporal changes in agricultural land cover in Nepal over the last 100 years
In order to advance land use and land cover change (LUCC) research in Nepal, it is essential to reconstruct both the spatiotemporal distribution of agricultural land cover as well as scenarios that
Holocene carbon emissions as a result of anthropogenic land cover change
Humans have altered the Earth’s land surface since the Paleolithic mainly by clearing woody vegetation first to improve hunting and gathering opportunities, and later to provide agricultural
Three distinct global estimates of historical land-cover change and land-use conversions for over 200 years
Earth’s land cover has been extensively transformed over time due to both human activities and natural causes. Previous global studies have focused on developing spatial and temporal patterns of
Anthropogenic land use estimates for the Holocene – HYDE 3.2
Abstract. This paper presents an update and extension of HYDE, the History Database of the Global Environment (HYDE version 3.2). HYDE is an internally consistent combination of historical population
Uncertainties in the land use flux resulting from land use change reconstructions and gross land transitions
Abstract. Land-use and land-cover (LUC) changes are a key uncertainty when attributing changes in measured atmospheric CO2 concentration to its sinks and sources and must also be much better
Historical U.S. cropland areas and the potential for bioenergy production on abandoned croplands.
TLDR
High-resolution cropland inventories for the conterminous U.S. with a land-use model are applied to develop historical gridded croplands areas for the years 1850-2000 and year 2000, showing potential bioenergy production from these abandoned lands using a wide range of biomass yields and conversion efficiencies has an upper-limit of 5-30% of the current U.s. primary energy demand.
Sensitivity of land use change emission estimates to historical land use and land cover mapping
The carbon emissions from land use and land cover change (ELUC) are an important anthropogenic component of the global carbon budget. Yet these emissions have a large uncertainty. Uncertainty in

TLDR
A comprehensive assessment of global HANPP based on vegetation modeling, agricultural and forestry statistics, and geographical information systems data on land use, land cover, and soil degradation that localizes human impact on ecosystems suggests large-scale schemes to substitute biomass for fossil fuels should be viewed cautiously.
