  • In the Japanese village of Kamimomi, a small group of farmers began gathering their rice in extreme heat, two weeks earlier than usual.
  • 2
  • Kamimomi is in Japan's western Okayama prefecture.
  • 3
  • The area is called "the Land of Sunshine" because of its good weather.
  • 4
  • But farmers working in the mountainside rice fields say climate change is hurting the harvest of rice.
  • 5
  • Joji Terasaka farms in Okayama. He said last year a hot period dried up the rice.
  • 6
  • He added, "I am worried about that this year because it will be just as hot."
  • 7
  • This year Japan had its hottest July on record.
  • 8
  • The Japan weather agency said temperatures were 2.16 degrees Celsius higher than average.
  • 9
  • Worldwide, there has been a 1.2-degree Celsius rise in average temperature since 1850.
  • 10
  • Scientists agreed that warming needs to be limited to 1.5 degrees Celsius to prevent the worst effects of climate change.
  • 11
  • Last year, Japan had a poor rice harvest nationwide because of unusually hot weather.
  • 12
  • Officials say the drop in harvest in Japan was partly responsible for a shortage of rice this summer.
  • 13
  • The low supply of rice in markets forced sellers to limit each buyer to one rice bag.
  • 14
  • Yuji Masutomi is a researcher at the National Institute for Environmental Studies in Tsukuba, north of Tokyo.
  • 15
  • He said, "Perhaps people think that an increase of one degree Celsius in average temperature isn't much. But it's quite a big change for plants and crops."
  • 16
  • Masutomi said the rising temperatures also hurt the quality of the grain.
  • 17
  • Last year, the farming ministry noted that at least one-fifth of rice farms have reported a drop in quality from rising temperatures.
  • 18
  • "Not only is the appearance not good; people say the taste drops too," Masutomi said.
  • 19
  • Another problem the farmers in Kamimomi face is working under high heat.
  • 20
  • The average age of agricultural workers in Japan is nearly 69, among the oldest in the world.
  • 21
  • Older people are especially likely to suffer from the heat. For half of the year, farmers work in the heat to produce rice.
  • 22
  • To deal with climate change, the government is urging the use of heat-resistant varieties of rice.
  • 23
  • One strain, developed by a research center near Tokyo, is called Sai no Kizuna.
  • 24
  • Naoto Ohoka manages rice breeding at Saitama's Agricultural Technology Research Center.
  • 25
  • Ohoka said, "Last year and this year have been extremely hot, but even in those conditions, Sai no Kizuna maintained a certain level of quality."
  • 26
  • Sai no Kizuna was developed in 2012 to better survive high heat, wind and certain pests and diseases.
  • 27
  • Masutomi recommends that similar varieties of rice should be introduced across Japan by the 2040s.
  • 28
  • But it can take up to 10 years to develop a new strain.
  • 29
  • After it is approved for the market, farmers must then decide to grow it.
  • 30
  • The most widely grown strain of rice is Koshihikari, which does not do well in high heat.
  • 31
  • Even so, older farmers have not always been willing to change to other varieties.
  • 32
  • Farming ministry data show that heat-resistant varieties grow in only around 15 percent of Japanese rice fields.
