Water is primarily used in forestry and fishery, agricultural production (in its entire agri-food supply chain) and is used to create and/or transfer energy in varying forms.

Water quality is rapidly decreasing as a result of human activities such as deforestation, mining and dumping of chemicals waste generated by factories into water sources such as oceans, rivers and lakes. Food and agriculture are the largest consumers of water, requiring one hundred times more than we use for personal needs. Agricultural operations can also negatively affect water quality. Agriculture ~ Environmental Issues. Sustainable Agriculture. Agriculture uses approximately 70% of the world’s freshwater supply, and water managers are under mounting pressure to produce more food and fibre for a growing population while also reducing water waste and pollution and responding to a changing climate.

In agriculture, water must be of suitable quality to irrigate crops or provide drinking water for livestock.
