TLDR
In this article, an agricultural projection and greenhouse gas model are used to assess the impact of global cropland expansion on carbon emissions and the sensitivity of those estimates to modifications in assumptions concerning idle croplands, the degree of refinement in carbon coefficients, market responses, and yield increase.Abstract:
An agricultural projection and greenhouse gas model are used to assess the impact of global cropland expansion on carbon emissions and the sensitivity of those estimates to modifications in assumptions concerning idle cropland, the degree of refinement in carbon coefficients, market responses, and yield increase. The results indicate that the impact of cropland expansion on carbon emissions is extremely sensitive to model assumptions. This is particularly true with respect to the price-induced yield response. Given the available knowledge, it is very difficult to narrow the range of reasonable parameter values to tighten the set of results to a level that would allow robust policy conclusions.read more

TL;DR: In this article, the authors bring together perspectives of various communities involved in the research and regulation of bioenergy deployment in the context of climate change mitigation: Land-use and energy experts, land use and integrated assessment modelers, human geographers, ecosystem researchers, climate scientists and two different strands of life-cycle assessment experts.

Using Attributional Life Cycle Assessment to Estimate Climate-Change Mitigation Benefits Misleads Policy Makers
TL;DR: In this paper, a conceptually superior approach, consequential LCA (CLCA), avoids many of the limitations of ALCA, but because it is meant to model actual changes in the real world, CLCA results are scenario dependent and uncertain.
Indirect Land Use Change From Increased Biofuels Demand - Comparison of Models and Results for Marginal Biofuels Production from Different Feedstocks
TL;DR: In this article, the authors compared the ILUC results produced by different economic models for marginal increases in biofuel production from different feedstocks, and provided fundamental indications to policy makers on how to address the issue of ILUC in legislation.

TL;DR: This article found that corn-based ethanol, instead of producing a 20% savings, nearly doubled greenhouse emissions over 30 years and increased greenhouse gases for 167 years, by using a worldwide agricultural model to estimate emissions from land-use change.

TL;DR: This study analyzes the rich, pan-tropical database of classified Landsat scenes created by the Food and Agricultural Organization of the United Nations to examine pathways of agricultural expansion across the major tropical forest regions in the 1980s and 1990s and highlights the future land conversions that probably will be needed to meet mounting demand for agricultural products.

The global potential of bioenergy on abandoned agriculture lands.
TL;DR: The global potential for bioenergy on abandoned agriculture lands is shown to be less than 8% of current primary energy demand, based on historical land use data, satellite-derived land cover data, and global ecosystem modeling.

TL;DR: Factoring market-mediated responses and by-product use into this analysis reduces cropland conversion by 72% from the land used for the ethanol feedstock, thereby limiting its potential contribution in the context of California's Low Carbon Fuel Standard.
