4 Other Disadvantages
Unmaintained terraces can lead to mudslides
, the creation of deep gulleys and increased soil erosion, particularly in sandy soils or on extremely steep terrains. Terracing also has been shown to reduce soil quality via the leaching of important nutrients from the soil in some areas.
What are the negatives of terracing?
Disadvantages include the capital cost of building terraces, and the time required to maintain terraces. Terraces that
are not properly maintained will fail
, and such failures can lead to gully erosion and other problems.

What are the effects of terrace farming?
Nevertheless,
soil erosion and the loss of topsoil
are still major threats to terrace farming. Terracing affects the rate of soil erosion caused by water through its effect on local hydrology, runoff characteristics, soil moisture and soil characteristics (Chow et al., 1999).
Are there any disadvantages in terrace or step farming?
- Terrace farming can be dangerous at some point because it can lead to rainwater saturation in some hilly areas. …
- On the contrary, the consequence of overflowing water is that it causes more dangerous water runoffs.
- Terraces, in addition, may result in mudslides if not well managed.
Is terrace farming good or bad?
Terracing is one of the oldest means of saving soil and water. … Existing literature and information shows that terraces can
considerably reduce soil loss
due to water erosion if they are well planned, correctly constructed and properly maintained. If not maintained, they can provoke land degradation.
Is terrace farming expensive?
Terraces are one way to control soil erosion. Crop rotation and tillage practices also control erosion. … Terraces do require high capital investments, however. Costs may range from
$100 to $250 per acre
, depending on the type of terrace system.
Where is terracing most useful?
Terraced paddy fields are used widely in rice, wheat and barley farming in
east, south and southeast Asia
, as well as the Mediterranean Basin, Africa, and South America. Drier-climate terrace farming is common throughout the Mediterranean Basin, where they are used for vineyards, olive trees, cork oak, and other crops.
What are the pros and cons of intercropping?
- Reduction in soil runoff and controls weeds;
- Intercropping with cash crops is higher profitable;
- It acts as an insurance against failure of crops in abnormal year;
- Inter-crops maintain the soil fertility as the nutrient uptake is made from both layers of soil;
Why do farmers in hilly areas practice terracing?
Terraces
reduce both the amount and velocity of water moving across the soil surface
, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.
Is terrace farming still used today?
Today,
modern farmers are returning to the terrace farming
practices used thousands of years ago as a more practical and productive way to raise the most food with the least water. Tea farmers also take advantage of terrace farming.
What are the benefits of a terrace system?
Terrace systems are highly effective at
preventing excessive rill erosion
, eliminating ephemeral gully erosion, reducing sediment yield, conserving soil moisture, protecting landscape quality, and increasing land value. Terraces are topographic modifications that require soil displacement to construct them.
What are the benefits of terrace gardening?
- Reduce indoor temperature by 6- 8 degree and can reduce air conditioning cost.
- Reduce overall heat absorption of buildings and insulate the building against heat and cold.
- Convenience of safe, pesticide-free, healthy green and fresh vegetables.
What are the two advantages of terrace farming?
- Increases farmability and land productivity of sloped fields.
- Contributes to water conservation: slows down and reduces water runoffs, improves rainwater harvesting.
- Prevents soil erosion by decreasing rill formations.
- Boosts soil conservation.
- Reduces sedimentation and water pollution.
Is terrace farming sustainable?
These new terraced vineyards
do not look sustainable under existing environmental conditions
. … The results indicate that the modern terraces are unstable and may lead to a degraded environmental situation.
What is the process of terrace farming?
Terrace cultivation, method
of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope
. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.
