The self propelled robot navigates its way along a row of fruit trees, constantly checking its location to ensure its wheels are placed to within a few centimetres precision of where it needs to be. It takes many thousands of images and measurements of the tree canopy in a split second, assessing fruit quality, colour, size and ripeness. Based on the information collected, it harvests only fruit that is at perfect colour and ripeness. The fruit that is picked by the robot is then once again photographed several times. Blemished fruit is separated out. A wealth of information is collected by the robot about each individual piece of fruit, down to which individual bud on which branch on which tree it was picked from. This information is compiled and analysed to adjust future management decisions.

The supermarket shelves consist of fresh produce of colours, forms, shapes, sizes and tastes like we have never seen before. There is also food that has been produced by 3D printers, made to a precise formula to provide specific nutritional needs and more consistently than ever before possible to meet pre-determined flavour profiles.
Fresh produce is no longer just grown in rural areas. It is also grown in cities, in specially built warehouses, on city walls and rooftops, in closed loop systems that use recycled city water.
Consumers can scan a printed QR code on their fruit or vegetables to get nutritional information, recipe ideas and information on where the produce came from and how it was grown. This is matched against their individual taste preferences, determined by brain scans to provide suggestions on what they should purchase.
Am I talking science fiction, a future that our children may experience many years down the track? Absolutely not! This is picture that is almost a reality now and will more than likely occur within the next ten to twenty years.
Robotic technology is advanced and already exists in many arenas. Scientists tell us that we will quite possibly have commercial robotic apple harvesters within 10 years. Advanced breeding programs mean we are seeing a range of new and exciting fruit and vegetable cultivars coming onto the market at a rate never seen before. 3D printing is a reality and NASA is already creating food for the space program using that technology. Vertical farms and warehouse farms are already a reality.
These changes described alone may sound sterile and surreal, and like any change may invoke feelings of fear and trepidation. But these innovations will not replace our existing food system. Instead, they will add many new layers of complexity, richness and excitement to our food and serve to bring about different ways of producing food. Food will continue to remain at the centre piece of our social fabric and bring great pleasure and enjoyment.
Just as we have been innovating since the beginning of mankind, so we will continue to innovate. Australian agriculture continues to lead the way in innovation, steeped in a history of resourcefulness and incredible adaptability. Our modern farmers have to adapt and change their practices at a very rapid pace to stay competitive. They are constantly seeking to improve their management and find new tools to not only take care of our fragile landscapes, but also improve them, all the while seeking to provide safe and healthy food.
The modern farmer is a far cry from the stereotypical and sometimes patronizing images that often bombard our television screens and magazines. They are, in every sense of the word, professionals, going about doing their jobs to the very best of their ability. It is because of their constant innovation that our farming practices have evolved and that the quality and choice of food available to us today is greater than ever before.
We are spoilt for diversity in choice of how our food has been produced and the types of foods that are available to us. This is only a reality through innovation in all kinds of farming systems. As an industry, we are also fortunate to be able to provide a wide range of opportunities for enthusiastic individuals seeking innovation and diversity.
No matter what our food choices are, we can all be grateful for innovation.
