Available water

Availiable water examples

surface water in dams, rivers and lakes

Renewable resources

Resources that can regenerate or be regrown such as trees

non-renewable resources

resources that cannot be regenerated once they are used up such as oil or coal

continuous resources

resources, such as the sun, that will never run out no matter how much is used

potential water

Water that needs to be treated before we can use it or drink it

Potential water examples

Water as an environmental resource

Rivers and wetlands

Water scarcity

Physical and economical

Water scarcity- economical

naturally, there is water, but the region doesn’t have the right infostructure to access this water

Economical water scarcity cause

Caused by poverty, correct infustructure is exspensive

Water scarcity- Physical

When the demand of water is more than is naturally available

Physical water scarcity examples

Growing population

Water scarcity causes- population growth

Climate change, change of diet, equipment of treatment is broken, war and conflicts

Water scarcity- agriculture

forests cleared, land and water pollution, chemicals and fertiliers and Irrigation
