As Japan swelters, farmers turn to new heat-resistant rice varieties to boost staple crop

TL;DR

  • Farmers in Japan are adopting heat-resistant rice varieties to cope with rising temperatures and dry summers.
  • New strains like 'hinatamaru' are thriving despite conditions that previously damaged rice yields.
  • Extreme heat leads to immature, chalky grains unsuitable for the market, impacting farmers' income and national food security.
  • Saga prefecture is leading the adoption of heat-tolerant varieties, with nearly 67% of its rice acreage dedicated to them.
  • The development and spread of these new varieties are seen as a race against time, especially given Japan's aging farming population.
  • Farmers are also changing work practices, such as inspecting crops at night, and considering heat-loving crops like avocados.
  • Greenpeace Japan warns that heatwaves threaten iconic autumn crops, including rice, and emphasizes the need for systemic solutions beyond individual farmer ingenuity.
