in PDF format / The development of technologies like no-till requires novel approaches to research and development. Are complex technologies like no-till successful? If so, what were the factors that helped in this success? How do we build on these successes to help resource-poor smallholder farmers, for whom the technology promises significant economic and environmental benefits? These are some of the issues that are addressed in the new World Wheat Overview and Outlook series, which continues CIMMYT's well-known Facts and Trends series. This new report focuses on the technical, economic, and social conditions that are needed for no-till. It will be useful for researchers and organizations involved in the development and dissemination of this crop management technology, which could go a long way in alleviating many problems farmers face today.
Abstract.- Part 1 of this report (which is a continuation of CIMMYT's World Wheat Facts and Trends series under a new name) explores issues related to the development and adoption of no-till technology, especially in small-scale agriculture. It describes no-till's special features, the innovation systems through which the technology evolves, a new framework for the socioeconomic study of the development and adoption of no-till, and the methodological difficulties involved in measuring no-till's benefits and adoption. This information provides the context for a series of six case studies of no-till experiences among small-scale farmers in Latin America, Africa, and Asia (and largely in wheat cropping systems). Part 1 concludes by discussing key factors conditioning the effectiveness of no-till programs for small-scale farmers, including the implications for national and international agricultural research. Part 2 documents that wheat yield potential has grown more rapidly in marginal compared to favorable environments in recent years, explores the reasons for this growth, and discusses the implications for future wheat breeding research for marginal areas. Part 3 tracks current and future trends in the global wheat market, with special attention to policy in the United States, European Union, and China. Part 4 provides statistics on wheat production, consumption, yields, and other variables.
