Introduction to water conflicts
Water is a finite resource and its management is important. There are environmental refugees as a result of the lack of clean water.
There is an increasing population globally (7.2 billion) and therefore an increasing use of water. Climate change will…

The geography of water supply

The hydrological cycle
It is a closed system that globally the hydrological system is closed. In a river, it is an open system.

Threats to the hydrological cycle
1. URBANISATION-this decreases the surface runoff time (through the drainage system) which enables water to return to the
rivers/oceans. It is much quicker and so there is a higher possibility of flood risk. They cannot follow the normal system
because of the impermeable layer of…

Geology

Key information
PERMEABLE-water passes through the rock. Permeable rocks are known as aquifers.

AQUIFERS-this is an underground store of groundwater in porous rock. Water is extracted from subterranean stores mainly by wells
and boreholes.

TYPICAL MISTAKE-candidates often lack an understanding of what groundwater is and how it is extracted.…

By 2050, in Colorado there will be approximately 9.5 million people and so will further pressurise this area of water if
management does not occur.
This area `belongs' to 7 states but is not equally distributed.

Reasons for water conflicts
Climate rain from the North Pacific Ocean causes the frontal…

They are the sole source of drinking water for about a ¼ of the population.

WATER SCARCITY-This is where water consumption reaches less than 1000m3 per person and this can be classified into physical
scarcity and economic scarcity:

PHYSICAL WATER SCARCITY-the shortages occur when demand exceeds supply.

Global water consumption…

In Bolivia, the prices charged by French-owned water companies were too high for the locals and 200,000 people chose not
to be connected the supply.

40,000 people in Detroit, USA were too poor to pay their water bills and resorted to illegal tapping.

Chemical fertilisers-they are used by farmers in order to increase the production of plants, yet they contaminate river and
ground water. Sewage and fertilisers add nutrients to the water and increase the growth of algae downstream which
removes the oxygen from the water- this is known as eutrophication.
Dams-they often…

The UN reports there are around 300 potential water conflicts around the world as rivers, lakes and aquifers struggle to
provide sufficient supplies for neighbouring countries.

What is the difference between surface water and ground water?
Surface water
This is through the use of rivers and basins, e.g. the Colorado…
