Methane from rice paddies accounts for approximately 40 percent of Japan’s methane emissions. Extending midseason drainage can reduce emissions by around 30 percent, but crop yields, biodiversity, food safety, and farmers’ workloads must also be considered.

Plastic-coated fertilizers helped Japanese farmers reduce physically demanding summer work and manage larger areas with fewer people. But the empty plastic shells can leave rice paddies and reach the sea. Why did Japanese rice farming become dependent on this technology?

Plastic-coated fertilizers reduce labor for rice farmers, but their empty shells can escape from paddies and travel through rivers to the sea. Can plastic-free fertilizers, drones, and biodegradable materials protect the environment without increasing farmers’ workloads?

Plastic-coated fertilizers help Japanese farmers reduce labor and use nutrients efficiently. But after the fertilizer dissolves, tiny plastic shells can escape from rice fields, travel through rivers, and eventually reach the sea.
