WHY IS WATER IMPORTANT TO THE HEALTH OF THE PLANET

2. THE HYDROLOGICAL CYCLE
Flows…stores (regulated…natural and man made)
Affected by rock type ..permeable impermeable, porous or non-porous, AQUIFERS

3. UNRELIABLE Seasonal changes Longer natural cycles Climate change
Case Study…Australia
World changes in supplies…increased demand…MEDC’s or LEDC’s

4. SUSTAINABLE Problems with water quality …rivers, aquifers, etc
Pollutions …eg Human sewage, toxic chemicals, plastic bags, heat, agricultural waste.
Disrupted supplies
Changing flows/stores (groundwater and extraction)
Case study = coca ~cola in Plachimada
= the Colorado River

5. Small-scale management
Intermediate technology
= lined wells
= handpumps
= rain barrels
Case study= AFRIDEV HANDPUMP IN TANZANIA
