It was launched in May 2022 with a two-year mandate. The GCEW is executed by an independent and diverse group of eminent policy makers and researchers in fields that bring novel perspectives to water economics, aligning the planetary economy with sustainable water-resource management.

Now, important part to read.

Recently Economics of Water report was released by Global Commission on the Economics of Water. All-important images relevant for you, I have taken from the report. Go through this.

Before you proceed images, understand the difference between blue and green water:

"Blue water" and "green water" are terms used to differentiate between types of freshwater resources, particularly in water management and agricultural studies:

1. Blue water refers to the water in rivers, lakes, aquifers, and reservoirs — essentially, all visible or "liquid" water sources that can be abstracted for human use.

Uses: This water is accessible for direct human use, such as in agriculture (for irrigation), domestic consumption, industry, and energy generation.

1. Green water is the soil moisture absorbed by plants and vegetation, mainly originating from rainfall. It is not available for direct extraction because it is stored in the unsaturated soil zone and used by plants through evapotranspiration.

A simplified illustration of the hydrological cycle.

Understand three terms:

Yes, biomass energy generation typically has one of the highest water consumption rates among renewable energy sources, especially when compared to solar, wind, and geothermal energy.
