This activity can result in eutrophication of local waters if nutrients are in excess.
Fertilizer
This activity can reduce windbreaks and increase erosion of soil in forested areas.
Clearcutting
This activity can lead to aquifer depletion and soil salinization.
Irrigation
This activity can decrease ground cover and lead to desertification of soil due to activity of livestock.
Grazing
