Catalyst: Would you eat insects?

A lot of resources go into the production of beef. For example, 20 litres of water is needed to produce just 1 gram of beef. In order to produce food more sustainably to feed an ever-growing population, some alternatives to protein have been suggested. What are some of these alternatives? Do you think they will ever replace meat?

Catalyst: What are modular farms?

Modular farms are flexible and self-contained systems that allow you to grow herbs and vegetables without the need for soil or sunlight. What are some advantages of modular farms? What may be some of the disadvantages?

Video

Landline: Drones and bugs

We don't normally associate robotics with farming but, in fact, robotics have revolutionised farming and agriculture in recent years. Find out how some strawberry farmers are using drones to disperse 'good' bugs for pest control management. Can you think of some other ways drones could be used to help farmers?

Solar thermal electricity

This program gives an update on research into solar thermal electricity. Liddell Power Station in the Hunter Valley, NSW is a hybrid power station using solar energy to pre-heat water and so reduce the use of coal and the production of carbon dioxide. Some scientists claim that harnessing the solar heat in an area 50km ...

Chemicals on the Great Barrier Reef

This program deals with a range of human impacts on the Great Barrier Reef. Herbicides from land runoff have been traced to algae and sea grasses in river mouths and coastal zones along the Great Barrier Reef. Effects include retardation of photosynthesis and growth of corals. Other pressures on the reef include high water ...

Catalyst: Water through cracked soil

Watch scientists investigate water movement through soil that has been cracked by drought. Australian scientists demonstrate a new way to investigate how water moves through the cracks using electrical probes to measure soil moisture at different soil depths. This technology could help farmers more efficiently irrigate ...
