What is Water Scarcity in Physical Form?
When a region’s natural water supplies are not enough to meet its needs, physical water scarcity results. In other words, regardless of infrastructure or financial resources, there simply is not enough water.
It typically happens in dry, arid areas with: • Little precipitation
Increased population growth and high evaporation
Intensive farming

⚠️ Physical Water Scarcity Causes:
1. Geography and Climate
o Places with high temperatures or little precipitation, such as deserts; o Prolonged dry seasons or droughts
2. Excessive Water Resource Use
o Lakes and rivers are being drained more quickly than they are being replenished o Groundwater is being overpumped
3. Climate Change o More severe droughts o Less consistent rainfall o The melting of glaciers that supply water to rivers
4. Increase in Population in Arid Regions
o As the population grows, more water is required for agriculture, drinking, and sanitation.

🌍 Locations With Physical Water Scarcity Examples:
• Middle East and North Africa (MENA): Contains some of the world’s driest nations, including Egypt, Saudi Arabia, and Somalia.
• Central Asia: The Aral Sea has significantly diminished as a result of excessive irrigation use; • Parts of Australia: particularly the Outback and western regions; • Southwestern USA: States like Arizona and California frequently face droughts and water shortages;
🔄 Physical Water Scarcity’s Effects:
• A decline in crop output and a scarcity of food
Degradation of the environment (dry rivers, loss of animals), pressure on industry and energy production, and forced migration from arid regions

Desalination: transforming saltwater into freshwater, which is utilized in countries like Israel and the United Arab Emirates; effective irrigation: drip irrigation minimizes agricultural waste; recycling and reusing water; and importing crops that require a lot of water instead of
