Meet Professor Salah Sukkarieh

robot r invento

Professor Salah Sukkarieh is Professor of Robotics and Intelligence Systems at the Australian Centre for Field Robotics.

As an engineer, he is using robotics and Artificial Intelligence (AI) to change the landscape of farming.

1 What is agriculture technology or ‘agritech’?

It’s technology that helps farmers. It can be sensors to monitor soil health or plant growth, energy-efficient tractors, drones that assess if there are new plants or diseases, or smartphones that can be used to control irrigation systems.

2 How did you get involved in agritech?

I’ve always loved engineering and technology, and the environment. Meeting farmers, I started to understand the complexities of farming and their struggles.

3 Do agritech robots just live on land?

No! Drones are agritech robots and people are starting to look at underwater robots for aquaculture.

4 What are the next challenges for agritech robots?

It’s important to understand how appropriate the technology is for each type of crop. Using a robot on vegetables is very different to using a robot in tree crops, or around cattle.

5 Would agritech robots work in school gardens?

Yes - it means we will get the next generation of agritech farmers ready to work in very cool farms of the future - see Challenge 3!

6 Serious question – robots or dogs...which is a farmer’s best friend?

Dogs, but the robots help farmers to free up time so they can spend more time with their best friends!

“The robots are electric, or solar-electric, and can move around the farm on their own (autonomously). They have sensors on board to help identify weeds, pests, crops and animals. And they have tools that can do things like planting, weeding and spraying.”

Aussie agritech robots

Ladybird was our original robot for the vegetable industry and used for research.

RIPPA was used operationally on many farms around Australia.

– Professor Sukkarieh

Digital Farmhand was designed to work for small-holding farmers in Australia and Overseas.

SwagBot was built for the cattle industry. It can herd cattle and navigate uneven landscapes.

Meet Kylie Kwong Chef, cookbook author and local farmer Kylie Kwong is a famous face in Australia! You may have seen Kylie on MasterChef, her own cooking shows or even have one or two of her cookbooks at home. Kylie is a passionate chef who cares about where local food comes from and caring about her environment.

What are some of your favourite local or bush ingredients to work with?

I absolutely love the Australian native bush mint which grows in our local organic vegetable garden in South Eveleigh, planted by proud Cudgenburra/Bunjalung man Clarence Slockee.

It has a eucalyptus-type aroma, a tiny, pretty, dark leaf and is versatile in cooking. Apart from its deliciousness, it allows my chefs and I to pay respect, acknowledgement and support to the local First Nations community.

What do you love most about being a chef?

Cooking is my ‘love language’ feeding people is my way of expressing my love and warmth to others.

What’s your hot tip for making any dish better?

Always cook with produce that is ‘in-season’ because it will be super fresh, therefore it will taste its very best, it will be affordable because it will be in abundance, and it will suit the climate in which you serve and eat it.

Why is using local food better for the planet?

I love telling diners about our magical garden, especially how the students of our local school - Alexandria Park Community School - helped us plant and harvest over the last year. For me, that garden reflects true community and sustainability, there have been many hands and hearts in that garden. There are zero food miles involved, the food plants and herbs are as fresh as it gets.

What’s your favourite piece of tech?

My favourite piece of cooking equipment is my bamboo Chinese steamer basket set, because I love ’steamed’ food, like ‘steamed fish with ginger and shallots’ or ’steamed prawn hargows’.

Cultural farming Sometimes called firestick farming, this is when First Nations people burnt small areas of land and grasses.

This encouraged more growth to return, created new food sources for animals, and protected Aboriginal people from bushfires.

Fishing in the Sydney basin Gadigal people used shellfish to fish with. They cut the shells and moulded them into hooks to catch fish - they looked like lures as they were bright and colourful.

Our First Nations farmers Our First Nations farmers were the original innovators – could you incorporate some of these farming practices and ingredients into some of your ideas for the upcoming challenges?

Fish traps Aboriginal fisherpeople changed water levels in creeks and waterways to trap fish and eels. As eels could often slip through, they also made eel nets out of grasses. These early methods of farming are over 40,000 years old.

Harvesting by the stars Our First Nations farmers used the stars to work out their harvest times. When certain stars rose in the night skies, they knew it was time to pick various crops.

Challenge 1

Grow your own food

Industrial large-scale farming across the world has a huge impact on our land quality. The way we farm livestock and harvest our crops takes a toll on our soil and water systems and creates carbon emissions. Below are some of the key problems around farming today - could you find a solution (or become a micro-farmer)?

Could aeroponics be the solution?

Aeroponics gardens like the one above, use much less water than traditional farming and leave a smaller footprint on the earth. These systems use recirculated water in much smaller quantities than a normal farm requires. Small gardens like this also mean that you can pick local produce and save on food miles.

Challenge 2

e t s a w d o o f r u o y e Reduc Food waste is a huge problem in Australia. Every single one of us wastes around 300kg of food a year!

We actually throw out a third of what we buy. This wasted food ends up in landfill, where some of it decomposes.

Could you come up with some strategies to create less food waste?

What a waste!

Australian households throw out over 7.3 million tonnes of food waste per year 92% of household food waste goes to landfill

Research Australian organisations like OzHarvest. How do they tackle food wastage on a large scale?

Collect your ideas on a Jamboard and think about how you could apply it to your school community.

document each step of prep and cook

Food for thought Will you include all meals such as entrees, mains and desserts?

How will you gather the information? Will you interview your family members or people in your local community?

Will you test cook the food before you publish the recipe?

Tip: take photos and grab personal advice from the cooks in your life!

Are you using any food from your kitchen/school or community garden?

Is there a ‘hero’ ingredient?

Are you using any indigenous foods in your cooking?

1. Hunt and gather

2. Kids in the kitchen

Will your class collection contain simply recipes, or include interviews with family chefs, or stories about where the recipes come from?

Which countries do your class recipes come from? Create a Jamboard of countries or drop pins on Google Maps and build a global picture of your class!

Will you have pictures?

Are you a green thumb?

If you love thinking about food - whether it’s where it comes from or what your next meal is, you might be interested in one of these career pathways connected to food and farming.

Garden designer Professional gardeners and landscape designers use lots of tech to plan their designs. Not only can they organise what plants go where, they can also overlay irrigation plans and plan any structures to be built. Could you plan a garden design in Canva or Tinkercad?

Small scale farmer Could you take your school or community garden to the next level and sell the crops to raise funds (for an even bigger garden)? While you are gathering your current crop, why not start planning your next crop and plan a salad day or food festival at your school.

Food technologist Food technologists are the magicians behind many of the foods we eat. Not only do they explore the nutrition behind what we eat, some of them engineer smells and tastes down to the molecular level. They also can help us with storage and refrigeration recommendations.

Chef or caterer Do you love cooking and are you good at organising a kitchen?

Perhaps you can use your creativity to put together a three course meal! Chefs and caterers cook for small and large groups of people, run restaurants and even work at special events with certain types of food.
