What are the advantages of terrace farming?

Answer 1

The two primary benefits of terrace farming are that is slows the speed of water flowing down the slope, which allows for more water absorption, and that soil erosion is reduced, If the terracing is not properly maintained, erosion can increase and flooding can occur.

Answer 2

SUMMARY

- The intensive and frequent land use changes in the Mediterranean countries have

numerous and negative environmental impacItns .o rder to asses land degradation, several models and

cartographies have been prepared: Glasod, Corine, Italian Ministery of Environment and UNEP. The

future EC policies for agriculture and related soil conservation aspects must be oriented by these

documents as well as by the state of art of the main soil conservation practices. Needs for future

research are concerned withh e following fields:

1 ) Economical analyses of soil conservation practices;

2)

Remote sensing for detecting land degradation; 3) Natural Resources survey based on land and land

use units;

4) Constitution of bench mark soils; and 5) Correlation of similar land use in different

countries.

Key

words:

Land use changes, land degradation, soil erosion, environmental impact assessment,

landscape protection.

Answer 3

It's hard to grow stuff on a steep slope. By cutting terraces into the slope, making it look a bit like a giant staircase, humans could turn a nearly useless slope into several useful flat strips of land instead.

Answer 4

Prevents erosion, Allows you to plant on steep slope, and provides more usable land.

Answer 5

Terracing provides a physical barrier to soil erosion by water.

Answer 6

Flat, narrow fields stepping up the slope, horizontal tillage [ 90 degrees to the slope of the hillside ].

Answer 7

The farmers will build stone or sod walls to form sort of stair-like benches. The walls slow the erosion and water runoff process.

Answer 8

Not enough land and for watering
