Biofuel impact on food prices index and land use change

Biofuel Policies and Indirect Land Use Change

Impact of land use change on soil erodibility

Vulnerability of soil separates to detachment by water is described as soil erodibility by Universal Soil Loss Equation which can be affected by land use change. In this study it was attempted to quantify the changes of Universal Soil Loss Equation K-factor and its soil driving factors in three land uses including rangeland, rainfed farming, and orchards in Babolrood watershed, northern Iran. S...

Biofuel and Food-Commodity Prices

The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel price...

Dynamical Change of Pareto Index in Japanese Land Prices *

We investigate the dynamical behavior in the large scale region of non-equilibrium systems , by employing data on the assessed value of land in 1983 – 2006 Japan. In the system we find the detailed quasi-balance, which has the symmetry: x 1 ↔ a x 2 θ (x 1 and x 2 are two successive land prices). By using the detailed quasi-balance and Gibrat's law, we derive Pareto's law with varying Pareto ind...

Memorandum on Land Use Change and the Global Food System

The LUC (Land Use Change) term in an LCA assessment of a biofuel’s global warming effect (GW), while superposable for small excursions, is not independent of other events in the global food system. In particular, the GW effect of biofuel use resulting from remote land use change mediated by global grain markets is probably larger to the extent that food supplies are under pressure from whatever...
