On linking an Earth system model to the equilibrium carbon representation of an economically optimizing land use model
economically optimizing land global scale
2014/12/19
Human activities are significantly altering biogeochemical cycles at the global scale, and the scope of these activities will change with both future climate and socioeconomic decisions. This poses a ...
The Community Land Model underestimates land-use CO2 emissions by neglecting soil disturbance from cultivation
Community land model planting harvesting crops planting on soil carbon biogeochemical model cultivation soil carbon
2014/12/18
The Community Land Model (CLM) can simulate planting and harvesting of crops but does not include effects of cultivation on soil carbon decomposition. The biogeochemistry model DayCent does account fo...
The Nexus Land-Use model version 1.0, an approach articulating biophysical potentials and economic dynamics to model competition for land-use
Demand for food. Biomass energy Forest protection Land use Model equation biophysics
2014/12/10
Interactions between food demand, biomass energy and forest preservation are driving both food prices and land-use changes, regionally and globally. This study presents a new model called Nexus Land-U...
Land Use and Land Cover Change (LULC) in the Lake Malawi Drainage Basin, 1982-2005
AVHRR Lake Malawi Lake Surface Temperature MODIS Reflectance
2013/3/6
Changes in land use and land cover (LULC) in the drainage basin of Lake Malawi over the period 1982-2005 were estimated from satellite imagery, and possible relationships were evaluated among the four...

The opening up of China's industry towards market orientation has a distinct impact on natural resources as well as on social structures. The example of rubber introduction in Yunnan province (SW Chin...
Application of WaSiM-ETH model to Northern German lowland catchments: model performance in relation to catchment characteristics and sensitivity to land use change
WaSiM-ETH model Northern German lowland catchments model performance in relation to catchment characteristics sensitivity land use change
2010/9/10
The hydrological catchment model WaSiM-ETH (Water Balance Simulation Model) is a spatially distributed, process- and grid-based hydrological catchment model which was primarily developed to simulate t...
Land-use effects on flood generation – considering soil hydraulic measurements in modelling
flood generation modelling
2010/2/3
The investigation in the catchment of the Mulde (51°0'55" N, 13°15'54" E Saxony, Germany) researches the effect of afforestation measures on the soil hydraulic properties. The concept of a "false chro...
Modelling the effects of land-use and land-cover change on water availability in the Jordan River region
land-use land-cover water availability
2010/2/3
Within the GLOWA Jordan River project, a first-time overview of the current and possible future land and water conditions of a major part of the Eastern Mediterranean region (ca. 100 000 km2) is given...
Ignoring detailed fast-changing dynamics of land use overestimates regional terrestrial carbon sequestration
detailed fast-changing dynamics land use regional terrestrial carbon sequestration
2010/1/20
Land use change is critical in determining the distribution, magnitude and mechanisms of terrestrial carbon budgets at the local to global scales. To date, almost all regional to global carbon cycle s...
