Nearly 74% of North America's drylands are affected by desertification. Topography can contribute to soil salinization through its influences on water accumulation.

They will produce more crops peer seed, need less water, and can survive in warmer climates. adapting a plant or animal for human use. Thus, salinization reduces ecosystem varieties and threatens their normal conditions to exist. Another name for shifting cultivation, so named because fields are cleared by slashing the vegetation and burning the debris to yield a fresh crop the next year.
