If, as many climate change analysts speculate, industrial and other emissions of CO2 can be offset by substitution of biofuels, large areas of land, including agricultural land, may be converted to the production of biomass feedstocks. This paper explores the feasibility for the Missouri–Iowa–Nebraska–Kansas (MINK) region of the US of converting some agricultural land to the production of switchgrass (Panicum virgatum L.), a perennial warm season grass, as a biomass energy crop. The erosion productivity impact calculator (EPIC) crop growth model simulated production of corn (Zea mays L.), sorghum (Sorghum bicolor (L.) Moench), soybean (Glycine max L.), winter wheat (Triticum aestivum L.) and switchgrass at 302 sites...
The current economic collapse in the United States, which has now spread around the world, has multiple causes. One of them, the recent unprecedented run up in oil prices certainly helped destabilize our economic and financial system. The US appetite for imported oil and its gaping dependence on it has enriched our adversaries in the largest wealth transfer in human history. For the moment, the oil price bubble has burst, but it should give us great pause. For geopolitical security, climate stabilization, and economic sustainability, we must break the global addiction to oil and other fossil fuels, especially to achieve an 80 percent carbon emissions reduction by 2050. This paper examines the potential for second...
This bibliography was created over several years as an aid to a variety of PHS projects as well as my work at the Glenbow Archives. It aims to include all publications and audiovisual products from the Social Sciences and Humanities. Most government documents are excluded as they are accessible through Library and Archives Canada. I would like to thank my PHS colleagues for their contributions and suggestions, including David Finch, Peter McKenzie-Brown, Clint Tippett, Peter Savage, Micky Gulless, Frank Dabbs, Aubrey Kerr and Jack Porter. I would also like to acknowledge the assistance of Calgary book dealers, Cameron Treleaven and Tom Williams and former Oilweek editor Gordon Jaremko. Historians David Breen and...
