Farming Systems and Agronomic Perspectives on Changes in Farm Size
This presentation will describe the main patterns of crop and livestock intensification under population pressures, for example from free grazing to zero grazing. The path of intensification has a major influence on agronomic productivity and farmers’ well-being, including nutritional and health status. Most importantly, in many locations the decline in land availability has led farmers to draw down soil and water resources, in an effort to meet household consumption needs. New strategies to restore soil fertility and improve moisture retention on those farms are now being adopted, with an urgent need for continued research to develop and disseminate techniques suited to farmers’ new circumstances.
