Farmers are getting older and older, no one wants to plant land? The Japanese came up with a solution: let robots and unmanned tractors plant the land.
This weekend, the G7 National Agriculture Ministers Meeting was held in Niigata Prefecture, Japan. This is the first time in the past seven years that developed countries have explored how to cope with the surge in food demand in an age of aging.
Due to the high degree of urbanization and aging, farmers in many countries face unoccupied land after retirement. The average age of Japanese farmers is 67 years old.
According to Bloomberg News, Hiroshi Moriyama, the Japanese Minister of Agriculture, Forestry and Fisheries, proposed a new idea that Japan will use automatic tractors and backpack robots to replace retired farmers in the future.
US Agriculture Minister Tom Vilsack warned that if the problem of aging farmers is left open, food security in the world will be at risk in the future.
According to UN data, the average age of farmers in developed countries is 60 years old. The Japanese government plans to spend 4 billion yen ($36 million) in the new fiscal year starting in March to develop agricultural automation, in which 20 different agricultural robots are developed .
According to data from the Ministry of Agriculture, Forestry and Fisheries, Japan’s uncultivated land plan has doubled in the past two decades, reaching 420,000 hectares in 2015. About 65% of farmers in Japan are 65 years of age or older. The number of people willing to plant land is becoming less and less, leading to an increase in Japan’s dependence on food imports. Currently, about 60% of food supply depends on imports.
Kubota Corp., Japan's largest agricultural machinery company, has launched a fully automatic rice planting tractor. Automated tractors equipped with GPS positioning systems can self-fertilize and cultivate depending on soil conditions.
Iseki & Co and Yanmar Co are also working with Hitachi Ltd to develop automatic tractors and harvesters.
Japanese automatic agricultural machinery is not just a large equipment such as tractors. Kubota is developing a wearable robot that can help farmers harvest vegetables and fruits. The Ministry of Agriculture, Forestry and Fisheries expects that backpack-based robots can help older and women farmers to automate in fields where large equipment is difficult to use.
Japan’s JSC analyst Takaki Shigemoto told Bloomberg News that “using new technology to grow land can attract young people to farm, and the labor force participation rate in the agricultural sector will increase.â€
