Terracing at the Ancient site of Machu Pichu in the Cusco region of Pery. The Incans were known for their use of agricultural terracing and Machu Pichu’s extensive stone terraces are a prime example of this practice. Terraces created larger areas for growing crops and allowed use of the more intense and longer sunlight exposure on the mountain sides during the day. Terracing also prevented soil erosion, mudslides and flooding and allowed farmers to better control the amount of water that fed the crops.
