003 - Lakes and


Geographic Knowledge and Understanding

Growing human pressures on lakes and aquifers, including economic growth and population migration.


Population expansion and the possible development of economic activities will inevitably create negative processes which will impact upon our lakes and aquifers.


  • To be able to explain the pressure put upon lakes by humans due to an increasing population and the resultant economic growth.

  • To be able to explain the pressure put upon aquifers by humans due to an increasing population and the resultant economic growth.

Activity One - Detailed Example - Lakes

We have already looked at the impact that pollution has had on Lake Erie in the previous syllabus point and now we are going to investigate the lake even further to see how population and economic growth could have an effect. To record all of your information you are going to collect an A4 piece of paper and mind map the impact. I would recommend that you use a separate coloured pen for each key area. You will need to look out for the following points:

                  • Where is the actual growth?

                  • Why has the growth happened?

                  • What has been the impact?

                  • Is there any management of the area?

Activity Two - Detailed Example - Aquifers

For this section of the syllabus, we are going to focus on the Great Artesian Basin which is located in Austrailia. For this detailed example, I would like you to divide your A4 page into four and complete the following questions - one in each box.

      1. The location and scale of the Great Artesian Basin.

      2. The number of people dependent on the Great Artesian Basin.

      3. Why economic development depends on the Great Artesian Basin.

      4. The reasons why management of the Great Artesian Basin is needed.
