Population growth leads to increased demand for water for drinking, sanitation, agriculture, and industrial purposes, often exceeding the available supply.

Water scarcity typically leads to reduced biodiversity, as many aquatic and terrestrial ecosystems rely on adequate water availability.

Agriculture accounts for the majority of global water consumption, primarily for irrigation purposes.

Overdrafting refers to the excessive withdrawal of groundwater, leading to a decline in the water table and potential long-term depletion of the aquifer.

Increased water pollution exacerbates water scarcity by reducing the availability of clean and usable water resources.

Climate change, particularly in the form of rising temperatures and altered precipitation patterns, can lead to water depletion in arid and semi-arid regions.

Water depletion typically leads to a decline in water quality, as the remaining water becomes more concentrated with pollutants and salts.

Desalination refers to the process of removing salt and other impurities from seawater to produce freshwater.

Desalination typically has negative environmental impacts, such as increased energy consumption and the discharge of concentrated brine, which can harm marine ecosystems.

Rainwater harvesting involves collecting and storing rainwater for various purposes, such as irrigation, drinking, and household use.

Rainwater harvesting typically has positive benefits, such as reducing reliance on groundwater and improving water quality. However, improper implementation can potentially lead to increased flooding.

Water stewardship refers to the responsible management of water resources, considering the needs of both present and future generations.

Water stewardship aims to promote sustainable and responsible water use, thus discouraging unsustainable practices.

Water conservation involves implementing measures to reduce water consumption and minimize water waste.

Water conservation aims to reduce water consumption and minimize waste, thereby alleviating water scarcity.
