Google Earth, the Group on Earth Observations and the University of Sydney will develop the world's first real-time monitoring platform for rice fields globally. The ambitious project will help realise the Zero Hunger target of the United Nations 2030 Agenda for Sustainable Development Goals.
Rice is the staple crop for more than half the world's population and 10 percent of all arable land is dedicated to rice farming, but there are currently no accurate maps outlining rice yields and land use using consistent methodology.
"Accurate and up-to-date information on how much rice has been planted and how much harvest can be achieved is crucial to achieving global food and water security," said project leader Professor Budiman Minasny from the Sydney Institute of Agriculture at the University of Sydney.
"Working with our partners in Asia, we will use the Google Earth Engine to build the first real-time mobile application that will allow farmers, agricultural scientists, non-government organisations and government planners to manage land use to ensure food security in the world's rice bowls."
The real-time land-use data generated using Google Earth will be verified by field operators in India, China, Malaysia, Indonesia and Vietnam. This will allow the agricultural scientists to calibrate monitoring to ensure its accuracy worldwide.
These five partner countries make up more than 40 percent of the world's population. India, China and Indonesia are the world's three-largest producers of rice and together account about 60 percent of total world production.
Jointly developed with the Universiti Malaysia Terengganu, the mobile monitoring app - Paddy Watch - will allow farmers, scientists and agricultural economists to:
- determine the extent of arable land under rice cropping in near real-time;
- estimate potential yields;
- manage water use and water security;
- account for greenhouse gas emissions (paddy rice releases methane);
- develop policies for education, economic growth, gender equity and reducing social inequality.
The Paddy Watch app will build on work already undertaken in Malaysia and Indonesia by Professor Minasny and colleagues at Universiti Malaysia Terengganu. Using the Google Earth Engine and cloud computing technology the project will improve on that work using the latest deep learning techniques to forecast crop yields and water consumption.
Professor Alex McBratney is Director of the Sydney Institute for Agriculture and Professor of Digital Agriculture and Soil Science. He said this project "is digital agriculture writ large on a global canvas".
"Digital agriculture is post-industrial agriculture," he said. "This type of technology means we can have confidence in our ability to feed the world's population in a sustainable way."
The project announced today is one of 32 projects supported by the GEO-Google Earth Engine partnership, which incorporates more than 100 national governments working with the search engine company and its mapping agency. The consortium will have access to a Google Earth licence for two, valued by Google at $US3 million ($4.3 million), plus technical support valued at $US1 million.
Led by Professor Minasny at the University of Sydney, Paddy Watch is being developed in partnership with Universiti Malaysia Terengganu; the Indonesian Centre for Agricultural Land Resources Research and Development in the Indonesian Ministry of Agriculture; IADA Ketara, Ministry of Agriculture, Malaysia; the Institute of Soil Science at the Chinese Academy of Sciences; Indian Agricultural Research Institute; and RIICE remote sensing, Vietnam.
