As the average age of farmers globally creeps higher and retirement looms, Japan has a solution: robots and driver-less tractors.
The G7 agriculture ministers meet in Japan’s northern prefecture of Niigata this weekend for the first time in seven years to discuss how to meet increasing food demand as aging farmers retire without successors.
With the average age of Japanese farmers now 67, Japanese Minister of Agriculture, Forestry and Fisheries Hiroshi Moriyama is to outline his idea of replacing retiring growers with Japanese-developed autonomous tractors and backpack-carried robots.
US Secretary of Agriculture Tom Vilsack has warned that left unchecked, aging farmers could threaten the ability to produce the food the world needs.
The average age of growers in developed countries is now about 60, according to the UN.
Japan plans to spend ¥4 billion (US$36 million) in the year through March next year to promote farm automation and help develop 20 different types of robots, including one that separates over-ripe peaches when harvesting.
“There are no other options for farmers but to rely on technologies developed by companies if they want to raise productivity while they are graying,” said Makiko Tsugata, senior analyst at Mizuho Securities Co in Tokyo. “The government should help them adopt new technologies.”
Moriyama said at the beginning of a bilateral meeting with Vilsack yesterday that he wants to serve the guests premium Kobe beef, which Japan wants to promote overseas.
The amount of uncultivated farmland in Japan almost doubled in the past two decades, reaching 420,000 hectares last year, as farmers retired, data from the ministry show.
About 65 percent of growers are 65 years or older. The dearth of young people willing to take up farming has increased concerns that Japan’s reliance on food imports will deepen, with the nation already getting about 60 percent of its food supplies from overseas.
“Aging farmers are threatening the sustainability of agricultural communities in Japan as the population globally is expanding and raising the need to boost food production to meet demand,” Moriyama said in his opening remarks to the seven-member meeting.
“We, as the members of the Group of Seven nations, share common problems and want to discuss them together for a solution,” he said.
Kubota Corp, Japan’s largest maker of agricultural machinery, has already developed its first prototype autonomous tractor for use in rice paddies. Iseki and Co and Yanmar Co are also developing autonomous tractors and harvesters with Hitachi Ltd developing systems for farm machinery.
It is not just vehicles: Kubota is also developing and marketing a suit-like device to help farmers harvest and carry fruit and vegetables.
BUSINESS UPDATE: The iPhone assembler said operations outlook is expected to show quarter-on-quarter and year-on-year growth for the second quarter Hon Hai Precision Industry Co (鴻海精密) yesterday reported strong growth in sales last month, potentially raising expectations for iPhone sales while artificial intelligence (AI)-related business booms. The company, which assembles the majority of Apple Inc’s smartphones, reported a 19.03 percent rise in monthly sales to NT$510.9 billion (US$15.78 billion), from NT$429.22 billion in the same period last year. On a monthly basis, sales rose 14.16 percent, it said. The company in a statement said that last month’s revenue was a record-breaking April performance. Hon Hai, known also as Foxconn Technology Group (富士康科技集團), assembles most iPhones, but the company is diversifying its business to
Apple Inc has been developing a homegrown chip to run artificial intelligence (AI) tools in data centers, although it is unclear if the semiconductor would ever be deployed, the Wall Street Journal reported on Monday. The effort would build on Apple’s previous efforts to make in-house chips, which run in its iPhones, Macs and other devices, according to the Journal, which cited unidentified people familiar with the matter. The server project is code-named ACDC (Apple Chips in Data Center) within the company, aiming to utilize Apple’s expertise in chip design for the company’s server infrastructure, the newspaper said. While this initiative has been
GlobalWafers Co (環球晶圓), the world’s No. 3 silicon wafer supplier, yesterday said that revenue would rise moderately in the second half of this year, driven primarily by robust demand for advanced wafers used in high-bandwidth memory (HBM) chips, a key component of artificial intelligence (AI) technology. “The first quarter is the lowest point of this cycle. The second half will be better than the first for the whole semiconductor industry and for GlobalWafers,” chairwoman Doris Hsu (徐秀蘭) said during an online investors’ conference. “HBM would definitely be the key growth driver in the second half,” Hsu said. “That is our big hope
The consumer price index (CPI) last month eased to 1.95 percent, below the central bank’s 2 percent target, as food and entertainment cost increases decelerated, helped by stable egg prices, the Directorate-General of Budget, Accounting and Statistics (DGBAS) said yesterday. The slowdown bucked predictions by policymakers and academics that inflationary pressures would build up following double-digit electricity rate hikes on April 1. “The latest CPI data came after the cost of eating out and rent grew moderately amid mixed international raw material prices,” DGBAS official Tsao Chih-hung (曹志弘) told a news conference in Taipei. The central bank in March raised interest rates by
