Terrace farming is the process of cultivating crops on the sides of hills or mountains by planting on graduated terraces carved into the slope, or in other words, the practice of carving flat regions out of hilly or mountainous terrain to produce crops.
Terracing is an important type of landscape alteration in agriculture because it makes use of hillside land that would otherwise be too steep for cultivation. By decreasing the slope gradient, terraces decrease water runoff, which prevents loss of soil and helps retain water for irrigation uses.
