What do 'blue waters' refer to?

Soil moisture used by plants

Surface water resources

The term 'blue waters' refers specifically to surface water resources. This includes bodies of water such as rivers, lakes, and reservoirs that are directly accessible and readily available for various uses including drinking water, agricultural irrigation, and recreational activities. These water bodies are vital for ecosystem health and are often closely monitored for quality, availability, and sustainability.

In contrast, the other options involve different contexts of water resource management. Soil moisture pertains to the water held in soil that plants utilize for growth, while underground water sources refer to aquifers and groundwater, which are not visible from the surface. Lastly, rainwater collected for use is known as rainwater harvesting, which is a different method of utilizing precipitation for water supply. Therefore, 'blue waters' distinctly captures the concept of surface water resources.
