Carbon emissions from land-use change and management in China between 1990 and 2010
China has experienced enormous changes in land use in recent decades, which are largely driven by its unparalleled economic development. We analyze changes in vegetation and soil carbon storage between 1990 and 2010 resulting from combinations of land-use category conversion and management. Results demonstrate a major decline in grasslands (-6.85%; 20.83 × 106 ha) and large increases in urban a...
متن کاملAccounting for Carbon Dioxide Emissions
It is an adage of accounting to monitor what you can measure but there is concern that some elements can potentially be very important yet very difficult to evaluate. There are now many who care about accounting for CO2 emissions: from scientists interested in the global carbon cycle to environmentalists concerned about global climate change, regulators overseeing international or subnational a...
متن کاملUse of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change.
Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. By usin...
متن کاملSensitivity of Carbon Emission Estimates from Indirect Land-Use Change
We analyze the sensitivity of greenhouse gas (GHG) emissions from land-use change to modifications in assumptions concerning crop area, yield, and deforestation. For this purpose, we run a modified version of the Center for Agricultural and Rural Development (CARD) Agricultural Outlook Model, which was used previously to assess the impacts of energy price increases and biofuel policy changes on...
