This 2012 Global Food Policy Report is the second in an annual series that provides an in-depth look at major food policy developments and events. Initiated in response to resurgent interest in food security, the series offers a yearly overview of the food policy developments that have contributed to or hindered progress in food and nutrition security.

The National Park Service (NPS) and other land management agencies have interest in managing bison herds under “natural” conditions; yet demographic features of natural populations are not well described. One solution to this issue involves the analysis of historical bison (Bison spp.) jump data.

In this study we analyzed the large scale spatial patterns of river pH, alkalinity, and CO₂ partial pressure (PCO₂) in North America and their relation to river catchment properties. The goal was to set up empirical equations which can predict these hydrochemical properties for non-monitored river stretches from geodata of e.g. terrain attributes, lithology, soils, land cover and climate.

Whether ignited by lightning or by Native Americans, fire once shaped many North American ecosystems.

The family Centrarchidae is a principal and visible component of the ichthyofauna in most warmwater ecosystems in North America, and many of its species provide key recreational fisheries.

Trade liberalization has greatly accelerated the volume of traded agricultural products in past decades. As land resources become more limited in some countries, international trade plays an important role in compensating for land scarcity in these countries.

Biodiversity in rangelands is decreasing, due to intense utilization
for livestock production and conversion of rangeland into cropland;
yet the outlook of rangeland biodiversity has not been
considered in view of future global demand for food. Here we
assess the impact of future livestock production on the global

This is the rst paper that estimates the global land use change impact of growth of the bioenergy sector. Applying time-series analytical mechanisms to fuel, biofuel and agricultural commodity prices and production, we estimate the long-rung relationship between energy prices, bioenergy production and the global land use change.
