For Unit 3 Area of Study 2, students must be able to clearly articulate the aims of their selected case study and the strategies proposed to address its associated environmental challenges.
| Term | Definition | Example |
|---|---|---|
| Aim | The overarching objective or desired outcome of management | “Restore ecological flows to the lower Murray River and Coorong” |
| Strategy | A specific action or intervention designed to achieve the aim | “Purchase water licences from irrigators to increase environmental flows” |
Multiple strategies are usually required to achieve a single aim, and they often operate at different scales (individual, local, regional, national, international).
When evaluating a case study, structure your analysis as follows:
Strategies typically fall into several categories:
| Strategy Type | Description | Example |
|---|---|---|
| Regulatory | Laws, permits, restrictions, bans | Water extraction limits; species protection orders |
| Economic/incentive | Financial mechanisms, pricing | Water buybacks; carbon credits; conservation payments |
| Technological | Engineering, infrastructure, innovation | Constructed wetlands; fish ladders; drip irrigation |
| Educational | Awareness-raising, community engagement | Extension officers; environmental education programs |
| Restoration | Active ecological rehabilitation | Revegetation; predator control; weed removal |
| Voluntary/agreements | Non-binding but cooperative actions | Stewardship covenants; industry codes of practice |
For each strategy, consider:
- Does it address the root cause or only the symptom?
- Is it consistent with sustainability principles (especially precautionary principle, intergenerational equity)?
- What are the trade-offs for different stakeholders?
- What evidence exists that it is working?
| Element | Detail |
|---|---|
| Challenge | Over-extraction of water has reduced river flows, degraded wetlands, and caused ecosystem collapse in the Coorong and lower lakes |
| Aim | Restore sustainable water sharing between irrigated agriculture and environmental flows |
| Strategies | Water licence buybacks; water use efficiency programs; environmental water manager; regulated flow targets |
| Earth systems affected | Hydrosphere (flows reduced), Biosphere (wetland species declining), Lithosphere (salinisation of soils), Atmosphere (reduced evapotranspiration) |
VCAA FOCUS: Exam questions about case studies often ask you to ‘identify the aim’ or ‘describe two strategies’. Answers must be specific to your case study — generic answers score poorly. Practise articulating aims as clear outcome statements and strategies as concrete actions.
