Current patterns of agricultural expansion and intensification are bringing unprecedented environmental externalities, including impacts on water quality.
According to a new book titled “More people, more food, worse water? A global review of water pollution from agriculture”, water pollution from agriculture poses a serious risk to human health and the planet’s ecosystems. In many countries the biggest source of water pollution today is agriculture — not cities or industry — while worldwide, the most common chemical contaminant found in groundwater aquifers is nitrate from farming. We need a much better understanding of the causes and effects of agricultural water pollution as well as effective means to prevent and remedy the problem.
