Interpretive Summary:

Technical Abstract: Terraces are earthen embankments constructed across the prevailing field land slope. They have been used in differing forms for thousands of years in an attempt to protect steep land slopes from runoff induced erosion. Contour farming, where tillage and planting create ridges and furrows at nearly right angles to the field slope, is encouraged to facilitate reduction in sheet and rill erosion with or without terraces. Precision farming concepts and technologies have modified agricultural practices by introducing new opportunities to apply spatial precision to field operations. Implementation of precision technology has potential to enhance the design and implementation of both terraces and contour farming practices. This book chapter reviews the basic concepts of terracing and contour farming and describes the application of geospatial data and analysis to the planning, design and implementation process. A case study shows that terrace systems designed using these new methods can meet functional requirements with increased efficiency and at a lower cost than those designed using traditional methods.
