The development of political strategies in Canada to support the transition from conventional to sustainable agriculture has been limited by the absence of a comprehensive conceptual framework for identifying the most critical policies, programs, and regulations. In this paper, we propose a framework that uses an efficiency/substitution/ redesign spectrum to categorize both sustainable farming systems and government activities. The framework is then used to identify a diverse range of short, medium, and longterm strategies to be pursued by governments in Canada to support the transition. Strategies discussed include research, diffusion, and training; market development; and safety net programs and tax provisions. Finally, the implications and implementation of the redesign concept for food production, processing, and distribution are outlined.

Environmental concerns such as air pollution and soil degradation have led to increased interest in altrnate technologies and production practices. Alternate transportation fuel are being investigated along with their feedstock sources. This paper presents results of work carried out on Jerusalem Artichoke as a feedstock for fuel ethanol production.
