Newswise — March 8, 2021 – March 11, 2021 will be the 10th anniversary of the earthquake and tsunami that caused the meltdown of the Fukushima Daiichi Nuclear Power Plant. The March 7th Sustainable, Secure Food Blog explores how the accident is affecting today’s farming in the area.
According to blogger Miwa Yashima Matsushima, “The soils of the area were contaminated with radioactive Cesium. This radioactive Cesium has a half-life of thirty years. This means that it will take 30 years for half of the Cesium-137 to lose its radioactivity and turn into the safer form of barium. Unfortunately, if food were grown in that soil contaminated with radioactive Cesium, the food would also be contaminated with radioactive Cesium.”
While contaminated surface soils were removed and clean soil was added, the soil fertility remains poor. One farmer saw total carbon amount in his soil decreased by 75%. Increasing soil organic matter is a must when it comes to fixing the soil. Some farmers use manure, but the availability of livestock in the area is low.
Matsushima's team conducted experiments with green manure and chemical fertilizer to look for more solutions to fix the soil. To learn more, read the entire blog: https://sustainable-secure-food-blog.com/2021/03/07/what-are-the-long-term-effects-of-the-fukushima-disaster-on-local-agronomy/
