Abstract: type="main">

The development and adoption of zero tillage has profoundly transformed cropping systems in Western Canada. In this paper, we describe key drivers and aspects of this innovation process and quantify the overall economic impacts of adoption and the benefit cost of research development and extension, which accelerated the adoption. Estimating on-site and off-site benefits we find very high benefit–cost ratios, suggesting a need to maintain institutions that can foster the development of similar innovations.

Le développement et l'adoption des techniques sans labour (TSL) ont profondément transformé les systèmes de culture dans l’Ouest Canadien. Dans cet article, nous décrivons les principales causes et les aspects de ce processus d'innovation et quantifions les conséquences économiques de l'adoption et le avantage-coût de recherche-développement et vulgarisation, ce qui ont accéléré l'adoption. Estimer les bénéficies sur site et hors site nous avons trouvé que les ratios avantage-coût est très élevé, ce qui suggère la nécessité de maintenir les institutions qui favorisent le développement d'innovations similaires.
