This paper provides a review of agronomic management practices supporting sustainable crop production systems and intensification, and testifying to developments in the selection of crops and cultivars. The paper also describes crop farming systems taking a predominantly ecosystem approach and it discusses the scientific application of this approach for the management of pest and weed populations. In addition, it reviews the improvements in fertilizer and nutrient management which are at the basis of productivity growth and it describes the benefits and drawbacks of irrigation technologies. Finally, it suggests a way forward based on seven changes in agricultural development that heighten the need to examine how innovation occurs in the agricultural sector.
