For many new agricultural technologies, feasibility issues need to be considered before they can be adopted by farmers and businesses. This video explains why scientific verification and practical adoption of technology are both important and discusses the long-term aims of new technologies, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

New technologies in the agricultural industry can have environmental, social and economic impacts. This video explores the technology that targets methane emissions, how fruit yield and quality can lead to greater profitability and how commercial farmers actually interact with technology, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

Agricultural processes have a large-scale impact on natural resources and ecosystems and many businesses are turning to technology to help. This video introduces some issues that agricultural technologies aim to address, including water scarcity, farm waste and sustainability, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

Before agricultural technologies can be adopted by businesses, they need to be thoroughly tested and evaluated. This video looks at the techniques and systems researchers use to collect and evaluate data, such as internet-connected sensors and the SF6 tracer, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

Photosynthesis supplies all oxygen for life, and it began in the sea. Amazingly, it all relies on one basic kind of chemical reaction that was achieved over two billion years ago by cyanobacteria, and cyanobacteria living as endosymbionts in plants and phytoplankton still produce almost all our oxygen. This programme tells the story of the cyanobacteria, how they changed our planet and are involved in supporting its many life forms. We look at the four major groups that photosynthesise in the sea: cyanobacteria, eucaryote phytoplankton (microalgae), seaweeds (macroalgae), and seagrasses. These groups are responsible for supplying around half the oxygen we breathe—so in terms of understanding the processes that keep us alive, this is a very important story. Show Less

We often ask ourselves, how can I contribute to a more sustainable society? What’s the best thing I can be doing? Eat, Grow, Love travels across the globe to find that permaculture could well hold some of the answers. Six individuals living in very different climates each prove that designing systems that use permaculture principles really can be a solution. Show Less

How does food get from the farm to our table? In this program we trace the route cereals, fruits, vegetables and dairy products take to get from the point of origin to the consumer. We also explore why there are often several processing steps in between before it can reach your plate. Show Less

Objective: To learn about how changes in the pH affect plants and animals. Learning outcomes - students will be able to: 1. Identify the changes in the pH value of soil and its effect on the plants. 2. Recognise the changes in the pH value of soil, caused by acid rain, and the effects of this change. Show Less

Australia is the driest inhabited continent on the planet. Drought in many parts of this nation is a fact of life. At just about any point in time, somewhere in Australia will be experiencing drought. It poses challenges to many areas of society and the economy, particularly the agricultural sector. This program looks at drought in Australia. Featuring interviews with environmental scientist Dr Terry Walshe, together with vegetable farmer Peter Schreur and Mildura-based farmers Bob McCarthy and Neil Bennett, it explores the nature of drought in Australia, the climatic causes of drought, the environmental, social and economic effects of drought and strategies to manage drought. This is an excellent resource for middle to senior level students of Geography, Environmental and Agricultural Sciences. It is an interesting and informative resource for students of Geography and environmental studies. Show Less

Join us on a whirlwind tour of Australia's diverse natural and man-made environments. We kick off with the Great Dividing Range's impact on rainfall and human habitation, and then dive into the Great Barrier Reef, revealing the impact of global warming on this fragile ecosystem. Next we explore the indigenous connection with Kakadu National Park and Uluru, before examining the significance of the Murray-Darling Basin as Australia's food bowl. We conclude with the gradual erosion of the Twelve Apostles and two of Australia's most significant urban environments - Canberra, the nation's capital, and Sydney, the international face of Australia.

This program presents 4 case studies of sustainable agriculture: - Whole form planning: inputs, outputs, erosion control, soil management, tree planting, water management, and salinity control. - Landcare: Communities banding together. - Permaculture. - Inner city gardens. Show Less

This programme investigates the basic characteristics of aquatic and terrestrial environments, and the adaptations of the plants that live in those environments. Among the specific areas examined are: - Supporting structures and movement, including turbidity; - Gaseous exchange and light absorption; - Control of water balance via gains and losses; - Pollination and fertilisation.
