| Managing ecosystems and renewable resources | |
| Explain the cycling of nutrients, including water, carbon and nitrogen. | |
|
Explain how ecosystems and their management contribute to the development and use of a range of products and services in an agricultural context - harvestable resources, including water, edible biota, biofuels and forestry products - renewable resources, including provisioning of food, fibre, fuel, water and pharmaceuticals for human and veterinary use and consumption - regulating services, including carbon sequestration and climate control - supporting services, including nutrient and water cycling, air and water purification. |
|
| Discuss the impact of an agricultural activity by comparing water quality from different sources. | |
| Use of renewable resources | |
| Describe current renewable resource consumption trends (including two of the following: food, fibre, forestry, fisheries or water) and assess their sustainability in relation to national and global population growth. | |
|
Explain how the availability and quality of fresh water at a local and regional level is influenced by - human activities, including provisioning of dams, urbanisation, resource extraction and pollution - natural processes, including salinity, siltation, drought and algal blooms - government policy, i.e. water buybacks - water use efficiency measures on farms. |
|
| Interpret data to draw conclusions about the use of biota. |
