Through Agriculture, Water scarcity and Water pollution

Water is a necessity for all forms of life as well as industries on which humans are reliant, like technology development and agriculture. This global need for clean water access necessitates water resource policy to determine the means of supplying and protecting water resources. Water resource policy varies by region and is dependent on water availability or scarcity, the condition of aquatic systems, and regional needs for water. Since water basins do not align with national borders, water resource policy is also determined by international agreements, also known as hydropolitics. Water quality protection also falls under the umbrella of water resource policy; laws protecting the chemistry, biology, and ecology of aquatic systems by reducing and eliminating pollution, regulating its usage, and improving the quality are considered water resource policy. When developing water resource policies, many different stakeholders, environmental variables, and considerations have to be taken to ensure the health of people and ecosystems are maintained or improved. Finally, ocean zoning, coastal, and environmental resource management are also encompassed by water resource management, like in the instance of offshore wind land leasing.

As water scarcity increases with climate change, the need for robust water resource policies will become more prevalent. An estimated 57% of the world's population will experience water scarcity at least one month out of the year by 2050. Mitigation and updated water resource policies will require interdisciplinary and international collaboration, including government officials, environmental scientists, sociologists, economists, climate modelers, and activists.

Water as a resource

When considering its utility as a resource and developing water resource policy, water can be classified into 4 different categories: green, blue, gray, and virtual water. Blue water is surface and groundwater, like water in rivers, lakes, and aquifers. Green water is rainwater that was precipitated on soil that can be used naturally for plants and agriculture. Gray water is water that has been contaminated by human use or proximity. The gray water classification can range from freshwater fertilizer runoff pollution to water contaminated from dishwashers and showers. Virtual water is the water consumed to make an agricultural or industrial product. Calculating virtual water of a commodity is used to determine the water footprint of a country and see how much water they are importing and exporting through their goods.
