Water crisis
*
Increase in the need of FOOD
Increase in consumption of WATER.
Excessive ater consumption Overpopulation
Increased VITAL NEEDS

This is very little water for human
progression…
…We arrive at these effects•Exploitation of aquifers
•Exploitation of rivers
•Construction of infrastructures
•Environmental degradation
•Discharges.
• Great artesian basin in Australia – 1.750.000 km3
• Ogallala Aquifer in USA - 450.000 km3
• Aquifer Arabia in Asia - 160.000 km3
• Guaraní aquifer (South America) – 1.200.000 km3
Exploitation of aquifers
Aquifer Guaraní (South America)
Exploitation of rivers
1. As a consequence, the Jordan River is endangering the Aral Sea.
2. Chemical Industry, Nuclear Centre, Textil Industry, Fish industry.
Discharges
Global Warming effects
• Melting
• Sudden Atmospheric changes
• Depletion of aquifers.
• Biodiversity.
• Displacement of ecosystems
• Health.
Melting snow and ice Reserves
• Kilimanjaro
• Himalaya
Depletion of aquifersSalinization of aquifers caused by water shortage
Salinization of aquifers caused by water extractionAlteration of the ecosystem
Biodiversity: Fauna and flora

Biodiversity: Health
Water Cycle Changes
Direct aspectsWe need more quantity & better distribution
Indirect aspectschanges in the climate of the planet,
global warming
We need :
•Money for investigation
•Good Global Water Politics
•Change of mentality
EffectsUnequal quantitative distributionIndustry and agricultureConsumptionPopulation growthPollutionEnergy sourceTemperatures increase evaporation
UN
Challenges and commitments
Challenges facing life and welfare
Ensure food supply Water and energy
Water and cities
Water and industry
Protect ecosystemsMeet basic human needs
Challenges for management: governability
Manage risks
Valuing water Ensure basic knowledge
Sharing water resources
Manage water wisely
