A group of aging farmers in Japan is facing extreme temperatures while striving to maintain the country’s vital rice crop. In the remote village of Kamimomi in Japan’s western Okayama Prefecture, a small group of rice farmers kicked off their latest harvest in sweltering heat, two weeks earlier than usual. The region, known as the “Land of Sunshine,” is experiencing challenges due to climate change, which is impacting the traditional staple of Japan’s diet.
Last year, a heatwave affected rice crops in the area, causing the grains to become smaller and thinner. Joji Terasaka, a rice farmer, expressed concerns about a similar situation this year due to the ongoing hot weather. July this year marked Japan’s hottest on record, surpassing average temperatures by 2.16 C (3.9 F) according to the Japan Meteorological Agency. It is crucial to limit global warming to 1.5 C (2.7 F) to prevent severe consequences like intensified heatwaves, storms, and irreversible ice melt.
The extreme heat has led to a decline in rice production in Japan, contributing to a nationwide rice shortage this summer. Supermarkets experienced empty shelves, with some retailers imposing purchase restrictions to cope with the limited stock. Rising temperatures above 27 C impact the starch buildup in rice grains, resulting in a reduction in quality. Research has shown that at least one-fifth of rice farms have reported a decline in quality due to increasing temperatures.
The aging agricultural workforce in Japan faces additional challenges from the heat, with the average age of workers nearly 69, making them susceptible to heat-related illnesses. Climate change impacts not only the yield and growth cycle of rice but also affects the grain’s quality. To combat these challenges, the government is promoting heat-resistant rice variants like Sai no Kizuna, developed to withstand high temperatures and maintain quality.
Efforts to develop more resilient rice strains are ongoing to address the rising temperatures. Although it can take up to a decade to introduce a new variant to the market, researchers are determined to create varieties tolerant of even higher temperatures. It is crucial for farmers to embrace heat-resistant variants to ensure the sustainability of rice production in Japan. The community in Kamimomi is collaborating on projects to revive abandoned paddy fields, combating the challenges posed by climate change and an aging workforce.
In conclusion, the impact of climate change on Japan’s rice farmers highlights the urgent need for sustainable agricultural practices and innovative solutions to ensure food security amidst challenging environmental conditions. The resilience and determination of these farmers in adapting to changing climates serve as a crucial example for agricultural communities worldwide.
