Answer 1

Answer:

D) I, II and III

i. Shelter Belts

Strong wind typically carry enough force to destroy the surface of the farm's land, which will accelerate the rate of land degradation. Usually, farmers put shelters belts at the edge of the farm to block such winds and prevent the soil degradation.

ii. No till farming

In this method of farming, Farmers avoid the use of tools that will destroy the composition of the soil (Such as shovel or rake).  They plant the crops by creating as little disruption as possible to the soil to prevent soil degradation

iii. Animal graze over plowing.

The concept is similar to no-till farming. Animal plowing usually conducted by making a buffalo carried a giant rake to destroy the soil and provide spaces for Fertilizer. Animal graze will eliminate the use of the rake and prevent soil degradation.
