Nippon Telegraph and Telephone West Corp. announced Monday it has developed a reporting system via e-mail to alert farmers of monkeys intruding in their fields using integrated circuit tags.
NTT West will put battery-powered radio frequency identification IC tags on one monkey in each group so that the monkeys can be detected by a special apparatus in the fields when they intrude and their location reported to farmers by e-mail on their cellphones, the company said, adding the system is aimed at reducing damages to farm products caused by such monkeys.
According to a survey by the Ministry of Agriculture, Forestry and Fisheries, there were 20.6 billion yen in farm product damages caused by wild animals nationwide in fiscal 2004.
NTT West said the new system will also reduce the burden on farmers who are now forced to maintain constant surveillance of such monkeys as they can easily sneak in through fences set up around the fields.
Under the new system, the farmers are required to go to the fields to clear out the monkeys only when they receive such reports of their entry.
According to NTT West, the apparatus for the system costs 2.1 million yen.
