This subfield studies the dynamics between water as a resource and issues such as water scarcity, water pollution, and water use behavior.

- "Water resources are natural resources of water that are potentially useful for humans..."
- "97% of the water on Earth is salt water..."
- "...only three percent is fresh water..."
- "Slightly over two-thirds of this is frozen in glaciers and polar ice caps."
- "Natural sources of fresh water include surface water, under river flow, groundwater, and frozen water."
- "Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater."
- "Human uses of water resources include agricultural, industrial, household, recreational and environmental activities."
- "Water resources are under threat from water scarcity, water pollution, water conflict, and climate change."
- "Fresh water is a renewable resource..."
- "...with depletion occurring most prominently in Asia, South America, and North America..."
- "Asia, South America, and North America..."
- "it is still unclear how much natural renewal balances this usage..."
- "...and whether ecosystems are threatened."
- "...for example as a source of drinking water supply or irrigation water."
- "The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air."
- "Asia, South America, and North America..."
- "Artificial sources of fresh water can include treated wastewater (wastewater reuse)..."
- "Human uses of water resources include agricultural, industrial, household, recreational and environmental activities."
- "Water resources are under threat from water scarcity, water pollution, water conflict, and climate change."
- "yet the world's supply of groundwater is steadily decreasing..."
