Advanced biofuels will be developed using cellulosic feedstock rather than grain or oilseed crops that can also be used for food and feed. To be sustainable, these new agronomic production systems must be economically viable without degrading the soil and other natural resources. This review examines six agronomic factors that collectively define many of the limits and opportunities for harvesting crop residue for biofuel feedstock in the midwestern United States. The limiting factors include soil organic carbon, wind and water erosion, plant nutrient balance, soil water and temperature dynamics, soil compaction, and off-site environmental impacts. These are discussed in relationship …

Canada has a long and diverse but largely disappointing record in integrating environmental and sustainability considerations into the development of policies, plans, programs and other strategic undertakings. For over 25 years, the federal government has had a policy-based strategic environmental assessment (SEA) process. In 2003, the deficiencies of this process led the House of Commons Standing Committee on Environment and Sustainable Development to recommend establishment of a legislated framework for mandatory SEA before the 2010 Parliamentary review of environmental assessment. Governments since then have not acted on this recommendation but have promised to strengthen federal SEA. In this paper, we …
Business Sustainability And Undergraduate Management Education In Australia, Josie Fisher, Ingrid Bonn
Business Sustainability And Undergraduate Management Education In Australia, Josie Fisher, Ingrid Bonn
Ingrid Bonn
There is a large and rapidly expanding academic literature arguing that there is an urgent requirement for businesses to become more sustainable. There is also a demonstrated need for managers to develop a better understanding of sustainability and the appropriate strategies required to improve business sustainability. In addition, there are international calls for educators to address sustainability in their programs. The aim of this study was to investigate the extent to which business sustainability is being incorporated into undergraduate business and management courses in Australian universities. The high percentage of international students enrolled in these courses suggests our findings have …
Making The States Full Partners In A National Climate Change Effort: A Necessary Element For Sustainable Economic Development, John Dernbach, Robert Mckinstry, Thomas Peterson
Making The States Full Partners In A National Climate Change Effort: A Necessary Element For Sustainable Economic Development, John Dernbach, Robert Mckinstry, Thomas Peterson
John C. Dernbach
This article explains why states and localities need to be full partners in a national climate change effort based on federal legislation or the existing Clean Air Act. A large share of reductions with the lowest cost and the greatest co-benefits (e.g., job creation, technology development, reduction of other pollutants) are in areas that a federal cap-and-trade program or other purely federal measures will not easily reach. These are also areas where the states have traditionally exercised their powers—including land use, building construction, transportation, and recycling. The economic recovery and expansion will require direct state and local management of climate …
