World Regions Facing the Most Severe Freshwater Scarcity

The most water-stressed regions globally include:

• Middle East and North Africa (MENA): 5% of world's population, only 1% of renewable water; climate change accelerates scarcity.
• Sub-Saharan Africa: 12% of population, 4% of water; droughts increasing in frequency and severity.
• South Asia: 25% of population, 8% of water; glacial melt and groundwater depletion are critical.
• China: 20% of population, 7% of water; northern regions face acute shortages.
• India: 18% of population, 4% of water; severe groundwater depletion and erratic monsoons.

Water scarcity drives disease, malnutrition, poverty, conflict, and displacement in these regions.
