- High Pressure Hazard Case Studies
- Mid-West USA (Arizona and California)
- Cause- High Water Usage And Low Rainfall
- Australia (The Big Dry) 10 Year Drought- Murray-Darling Basin
- Effect
- Rudd government outed over lack of attention to the subject
- Areas oldest trees are dieing proving its the worst they've expernienced
- States are arguing over water rights
- Farmers struggling to stay in business, production has declined by half in some areas
- Causes
- ENSO brings drought
- Enhanced Greenhouse effect
- Erratic rainfall patterns
- 20% drop in rainfall= 70% drop in stream flow
- Overallocation of water
- Management
- Government water buying back water allocation
- Farms are diversifying there income to survive- Ecotourism, Farm museums etc.
- Effect
- Southern Zambia
- Causes
- Deforestation blamed for increasingly arid nature
- Poor soil is easily eroded
- Management
- Terracing used to reduce soil erosion
- Pipes created to improve water retention
- Wells created despite high labour input
- Effects
- Crop surveys show decreases in the yield of cash and food crops
- Reduced productive capacity
- Economic decline stops measures to reduce risk
- Crop surveys show decreases in the yield of cash and food crops
- Causes
- Kenya 2009
- Effects
- MDG's Are Threatened Eg.Eradicate Poverty, Food Security And Environmental Sustainability
- Economy Is Focused Heavily On Rain Due To Reliance On Agriculture
- Livestock and Crops died that were required as food and cash crops
- Causes
- Arid/Semi-Arid Land Cover 80% Of Territory
- Dependent On Rainfall
- Management
- International Aid Sent
- Fortunate ones migrate to escape further problems
- Effects
- Water War (Jordan River)
- Management
- Religious sites restrict engineering
- Possible Solutions
- Improved Irrigation
- Dam Construction
- Desalination
- New limits on usage
- Effects
- Jordanians feel they are suffering due to Israels overuse
- Causes
- Water shortages causing tensions between Jordan, Israel, Syria and Lebanon
- Tension Already Present due to religion
- Overuse in the upper regions of the river (Israel)
- Pollution while it runs through Israel
- Yarmouk river which replenishes the Jordan us drained by Jordan and Syria
- Management
- Mid-West USA (Arizona and California)
