What type of water is referred to as "green water"?

Green water refers to the soil moisture that is available to plants. This type of water is crucial for agriculture and ecosystems, as it represents the water held in the soil that can be absorbed by plant roots. It plays a vital role in the growth and health of plants, impacting food production and the sustainability of natural habitats.

The concept of green water emphasizes the significance of rainfall that infiltrates the soil, contributing to the moisture necessary for plant growth rather than surface water sources, such as rivers and lakes, which are classified differently. This distinction is essential in discussions related to water management, especially in semi-arid regions, where soil moisture is a critical factor for water usage in agriculture and vegetation. Understanding green water helps in appreciating the interplay between water resources and terrestrial ecosystems.
