Question

which of these can result in desertification of rangelands? windbreaks, careful plowing, and few livestock overgrazing of livestock leading to wind and water erosion fertilizing pastures and making sure that there are few livestock grazing careful irrigation practices combined with moving livestock often

Explanation:

Desertification of rangelands occurs when the land degrades due to various factors. Overgrazing by livestock removes vegetation cover. Without plants, the soil is more vulnerable to wind and water erosion. Wind can blow away the top - soil, and water can wash it off. This continuous erosion makes the land less fertile and more like a desert. Windbreaks (like rows of trees) help prevent wind erosion, careful plowing can be a conservation - tillage method, and having few livestock (not overgrazing) are all practices that help prevent desertification. Fertilizing pastures and having few livestock grazing and careful irrigation with moving livestock (rotational grazing) are also management practices that maintain or improve rangeland health.

Answer:

overgrazing of livestock leading to wind and water erosion
