Exam Practice

Evaluate the strategies that have been used to resolve competing demands for water in one named river basin [10 marks]

 

MARK SCHEME

Responses will depend on the river basin chosen. The river basin should be named and located.

The competing demands should be outlined and could include:

  • farming
  • industry
  • domestic supplies
  • recreation
  • power supply.

Strategies depend on the river basin selected but could include:

  • customer metering of water,
  • dams and reservoirs,
  • transfer of water,
  • zoning,
  • water use restriction (temporary or permanent),
  • customer advisory services,
  • the use of incentives for installation and/or retrofitting of water efficient equipment,
  • reduction of water use by the water utility,
  • leakage detection and repair programmes and pressure reduction,
  • regulation of the efficiency of water using appliances, especially in new buildings, and
  • use of reclaimed water (eg waste water/grey water) to reduce the need for fresh water supplies.

Good answers may discuss the varying power and/or perspectives of different user groups in relation to how a resolution is arrived at (commercial/human need for water may ultimately take precedence over the needs of ecosystems/wetlands, for instance) Another approach might be to evaluate the importance/success of strategies/actions.

Answers that do not refer to a named river basin and focus on demands only should not move beyond band C.

At band D, expect description of some strategies used to tackle water demand problems in a recognizable river basin.

At Band E, expect either more in-depth explanation of strategies, or some critical evaluation of how successful the strategies have been.

At band F, expect both.
