The extent and type of resource development in any society depends on the goals and values of that society. These goals and values are not determined in isolation but are historically and culturally conditioned. 

Two kinds of processes may follow from this realisation.

  • Firstly, better management and planning can be called for, aimed to minimise the 'less than desirable consequences of resource development; for example, State Governments in Australia legisl­ate to control exhaust emissions from cars to minimise the effect of these emissions on the environment. 
  • In addition, a re-evaluation and possibly modification of social goals may occur simultaneously. For example re-evaluation of the consequences of unrestrained personal urban mobility has lead to improved public transport systems.

Bob saw that the concepts of beach erosion caused by building too close to the coastline and the processes by which it occurred, fitted perfectly into this topic.

Teachers Information

Many Queenslanders live within one hours drive of the sea and many will spend their holidays at some type of coastal development. For schools that are on the coast, there is a special type of coastal environment which pervades the lifestyles of students.

It is important for students growing up in this holiday atmosphere to realise the problems associated with it. Equally important is the problem of visitors to the coastal areas adopting codes of behaviour that are different to that of their normal lifestyle.  

Content
(a) General coastal features such as headlands, bays and beaches
(b) How waves are formed and affect the coast
(c) Coastal developments and engineering works (e.g. Groynes)
(d) Political implications of beach resource development
(e) Environmental implications of developing beaches, dunes or inland waterways
(f) The history of a local beach area
(g) Recreational activities that can be carried out on the coast
(h) Coastal disasters such as cyclones and floods and what to do when these occur
(i) Dangers associated with beaches and coastal bars
(j) Tides and their effects

Process
(a) Discuss different types of beach accommodation
(b) Compare different tariffs from different areas in Queensland (Lizard Island, Gold Coast)
(c) Collect information on different peoples attitudes to a local developmented.
(d) Debate the information collected rationally
(e) Understand the rules and regulations associated with Beach Homes, Units, Time Sharing etc.
(f) Understand local council building regulations regarding cyclones and floods

Skills
(a) Construct a model wave tank to illustrate principles of beech erosion
(b) Illustrate with the model the effects of groynes
(c) Use a phone book or newspaper or travel brochure to obtain tariffs for an area
(d) Plot a graph of tides over a month
(e) Go camping on the coast end as a result of this activity the
students should be able to: Demonstrate practical conservation methods Conduct a coast survey on a particular topic Catch, prepare and cook marine animals

Attitudes
(a) Become receptive to different arguments for coastal development
(b) Become aware of the fragile nature of the coast and the effects of cyclones
(c) Appreciate the need to be careful while camping
(d) Develop a respect for the surf or sea
(e) Tolerate different developers opinions and criticise only when well substantiated facts are available,

Electives
Wave models and harbour design; Coastal jobs; Foreshore Ecology
Project; Animals and Plants that inhabit the coast; Observe cyclone proofing on a construction site; study chainges that have occurred in a local area because of management.
