Trends of ETo and weather variables and related spatial patterns. The water used by plants is nonrecoverable, because some water becomes a part of the chemical makeup of the plant and the remainder is released into the atmosphere. Wastewater generated from food production and agricultural activities is a major source of environmental pollution. UN-Water.
