- Causes of Water Insecurity
- Physical
- climate - regions with high and low rainfall, climate change alters weather patterns and increases the differences
- Rajasthan, India experienced a reduction in aquifer recharge due to changes in evaporation and precipitation rates
- salt water encroachment - processes where groundwater near coast is contaminated with saltwater
- sea level rise, coastal erosion and local abstraction of groundwater increase the risk of saltwater intrusion
- Tuvalu - highest point is 3m above sea level, groundwater is contaminated, entered the soil and ruined the crops
- sea level rise, coastal erosion and local abstraction of groundwater increase the risk of saltwater intrusion
- climate - regions with high and low rainfall, climate change alters weather patterns and increases the differences
- Human Causes
- 20% of all aquifers are being over-abstracted - Rajasthan, India - Coca Cola bottling factories have abstracted so quickly that the water table dropped 15 meters in 10 years
- local farmers in search of water were drilling holes as well as their own wells - ran dry and led to protests
- Agricultural water contamination - e.g fertilisers and pesticides can be washed away by rainwater - can be too contaminated for human consumption
- agriculture is the largest use of water - 70% of global water for agriculture or 90% in developing countries
- Industrial water pollution - lack of regulation from waste entering rivers and water, mining causes metal e.g mercury into water, untreated sewage leads to bacteria being consumed by those using the water
- 20% of all aquifers are being over-abstracted - Rajasthan, India - Coca Cola bottling factories have abstracted so quickly that the water table dropped 15 meters in 10 years
