Terrace farming is a method of cultivation that is practiced on the slope of hills. It involves creating flat areas on the hillside in order to grow crops. This method is commonly used in hilly or mountainous regions where the land is not naturally flat. By creating terraces, farmers are able to prevent soil erosion and retain water on the slopes, which allows for more effective farming. The flat terraces also help to optimize sunlight exposure and make it easier to irrigate the crops. Terrace farming is not typically done in dry regions, on rooftops, or on mountain tops, as these environments may not be suitable for this particular method of farming.
