This review paper examines some of the issues concerned with sustainable production of two major cereal crops – wheat and rice. We compare the perceived threats to sustainability in intensive production of rice in Japan and wheat in Europe, and evaluate the contrasting experiences with minimum tillage as a possible technique for greater sustainability. The contrasts which are presented reveal how perceptions about environmental threats vary widely, and how social and economic factors, as well as purely environmental issues, greatly influence the conclusions reached about sustainability. Before drawing these comparisons, however, we present a brief outline of the two crop systems as practised in Japan and Europe, and describe the experiences in both regions of using minimum tillage. The comparison presented has shown that there are no simple solutions to the problem of sustainability. Management techniques which work well in one situation, for example minimum tillage for wheat, may be inappropriate for another crop. Furthermore, the search for sustainability is strongly constrained by social and economic circumstances which ultimately determine which management options are viable. Indeed, although awareness of the need for more sustainable agricultural practices is growing, both in Japan and Europe, short-term economic considerations continue to be the dominant influence affecting agricultural practice in both regions.
