Hence it is expensive as it is labor intensive. Another limitation of terrace farming is that thereâs need for huge inputs of labor to construct and maintain the terraces. The consequence of overflowing water is that it causes more dangerous water runoffs.Terraces may also result in mudslides if not well managed. This is dangerous since it causes the overflow of water during the rainy season. Terrace farming can lead to rainwater saturation. It also helps in retaining the soil nutrients in the farms. Terrace farming is able to turn the moist idle land into productive farms leading to high food security in the world. Hence it needs to be explored in other parts of the world such as Africa, America and other parts of the Asia that are not yet using it. Its absence would have led to most parts of Asia being unproductive. Terrace farming is an important agricultural method that has made farming in mountainous parts of the world possible. Lastly, terraces trap rainwater allowing the people to engage in cultivation of water-intensive crops such as rice. The fourth benefit of terrace farming is that it has made the idle hillside land become productive. Thirdly, terraces help in reduction of soil erosion and water loss. Sometimes rain water carries away the crops leading to low crop yield. Secondly, it prevents the carrying away of plants by the heavy flowing rivers of water.

This leads to the growth of healthy crops.

Terrace farming prevents the washing away of soil nutrients by the rains. On the contrary, the level terraces follow a contour line and are best suited for permeable soil. A graded terrace may have either constant or variable grades along its length. There are two types of terracing known as graded terracing and level terracing. This is because rice does not do well on high altitudes. On very high altitudes, other crops apart from rice can be grown. This helps in keeping some areas dry and others wet. Every step has an outlet which channels water to the next step. When it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace. Terrace farming is a method of farming whereby âstepsâ known as terraces are built onto the slopes of hills and mountains. Terrace farming is also commonly used in islands such as the Canary Islands, because they have hilly terrains.

Apart from rice cultivation, terraces are also used to grow rice, potatoes, and maize. In fact, the terraces of rice found in the Philippineâs Cordilleras have been acknowledged as UNESCO World Heritage Site. It is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia.

This farming method has made cultivation of crops in hilly or mountainous regions possible. Terrace farming is a type of farming that was invented by the Inca people who lived in the South American mountains.
