Summary:

Land use limitations and establishment of environmentally protected areas are legislative approaches to help meet water quality objectives and reduce waterway pollution due to nutrient leakage, for example nitrogen and phosphorous stemming from fertilizer use. These actions typically target agricultural activities as they are the main source of water nutrient pollution, and may require fertilizer use reduction to a specific limit, a pesticide use ban and establishment of fringe zones along watersheds where no agriculture is permitted.

Such measures are particularly important in areas with high ecological value, such as wetlands and forests, which contribute to improved watershed water quality, in addition to delivering a wide range of other water ecosystem services.
