    Automobiles are a major source of CO2 emissions. Because there is no immediate technological fix to reduce these emissions, the most promising current strategy is to promote less automobile use. In the United States, this is difficult because federal programs such as the interstate highway system and local land use planning and regulation have encouraged suburban sprawl. In 2006, the state of California passed legislation to roll back greenhouse emissions to 1990 levels by 2020. This legislation did not link the roll back target with land use policies.

    We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade.

    Forests, trees and woodlands cover almost one-third of the Earth’s land area. They are a crucial source of food and income for more than a billion people around the globe. They provide a variety of wood and non-wood products and vital ecosystem services – preventing erosion from wind and water, preserving water quality, shading crops and livestock, absorbing carbon which contributes to countering climate change, and providing habitat for many species of plants and animals, thus helping to conserve the planet’s biological diversity.

    The effects of landscape context on habitat quality are receiving increased attention in conservation biology. The objective of this research is to demonstrate a landscape-level approach to mapping and evaluating the anthropogenic risks of grassland and forest habitat degradation by examining habitat context as defined by intensive anthropogenic land uses at multiple spatial scales.

    United States policy makers are promoting bio-fuels as an economic development opportunity, especially for rural America. A USDA study claims that developments in energy production from biomass could increase profits for agricultural commodity producers. However, as William Heffernan and his colleagues have demonstrated, concentration in the agrifood sector limits the economic benefits going to the commodity producers.

    The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products. There is great interest in the potential of countries to expand their biofuel sectors through increased production of feedstocks. The long-term potential for developing first-generation biofuels in many countries depends on a large and constant supply of feedstocks.
