福岛制造。一种可持续的农业净化方法。

案例简介：为什么这项工作与创新相关？可持续的净化农业方法不是典型的创新。因为它不是有形的产品，也不包含现代技术。相反，这是一种科学方法，以一种新的方式将数百年来已知的工具和过程结合在一起。创造比大多数技术产品创新更大的影响: 有助于解决最近历史上最大的生态灾难之一: 福岛核灾难。背景 2011年3月11日，日本福岛县遭受了近代史上最大的灾难之一。太平洋地震引发的海啸袭击了福岛第一核电站，引发了核反应堆的熔化，导致爆炸和放射性物质释放到大气中。在接下来的几天里，风雨把放射性物质带到了内陆。过去是日本最重要的农业地区之一，超过25,000公顷的农田受到污染。官方的去污方法清除了肥沃的表土，并用山上的贫瘠污垢代替了它，产生了大量的放射性废物: 1600万平方米，存储在整个地区。但最重要的是: 通过清除肥沃的土壤，它使耕种变得不可能。因此，即使辐射减少，该地区仍然被遗弃，因为没有农业，福岛农村社区就失去了生计。描述这个想法来自METER的环境技术专家与东京大学的Masaru Mizoguchi博士，环境科学家和NPO Fukushima Saisei共同开发了一种创新的可持续农业净化方法: 它去除土壤中的放射性物质，而不去除土壤本身。该方法可以很容易地由农民自己应用，因为它只使用可用的资源。它使农民能够再次在祖先继承的田地上种植完全安全的水稻。而且由于它仅去除放射性颗粒而不是整个表土，因此与官方方法相比，它将放射性废物的数量减少了95%。通过把农民还给他们的田地，他们恢复了生计。这振兴了社区和企业。整个地区可以再次增长。开发过程中的关键日期是什么？ 1996年福岛县安装的第一个仪表环境传感器。 2011 03 11下午2:46 太平洋地区发生9.0级地震。 2011 03 11 太平洋地震引发的海啸袭击了福岛第一核电站，并导致反应堆堆芯熔化，导致爆炸和放射性物质释放到大气中。 2012年01 沟口雅人博士提出的去污方法核心思想。 2012 07 在福岛县Iitate举行的第一小组会议。 2013 07 在Iitate举行的第二次会议，测试不同的方法，一些科学出版物。 2014 - 2015 几次访问，方法的完善，土壤和水稻的长期分析，一些科学出版物。 2016 - 2019 几次访问，扩展到该地区的更多领域。描述创新/技术创新方法的核心是发现放射性铯与稻田中的粘土结合: 去除粘土，然后去除铯。创新的第二个 “要素” 是物理技巧: 粘土漂浮在水面上。通过淹没田地并搅动表土，粘土铯化合物上升到顶部，从那里可以将其排入田地旁边的坑中，并有效地干燥和储存。一次施用从土壤中去除80% 的铯，同时保持耕作所需的肥沃表土。在这些经过净化处理的田地上种植的水稻定期进行辐射测试，发现它们是完全安全的，远远低于官方规定的限制，该限制是美国和欧洲的10倍。由于该方法仅去除放射性铯和粘土，而不是整个表土，因此与官方方法相比，放射性废物的数量减少了95%。农民将其埋在远处，由于铯继续与粘土结合，因此它不会在土壤中移动，并且可以安全地腐烂。这消除了大型核废料储存场所对环境和心理的影响。描述期望/结果可持续去污法一次施用即可去除土壤中80% 的铯。农民自己利用现有资源将其应用于福岛县的许多稻田。在经过净化的田地上种植的水稻是完全安全的，比福岛县产品的官方测试限制低10倍以上，这是世界上最严格的辐射测试。与官方去污方法相比，可持续方法的应用r减少95% 的放射性废物，防止了数千立方米的放射性废物。福岛农民重获生计，从而恢复了社区和经济。福岛及其他地区的农民和组织正在采用这种方法。

案例简介：Why is this work relevant for Innovation? A sustainable decontamination method for farming is not a typical innovation. Because it’s not a tangible product and doesn’t contain modern technology. Rather, it’s a scientific method, combining tools and processes known for centuries in a new way. To create impact bigger than that of most technological product innovations: Contribute to solving one of the biggest ecological disasters in recent history: The Fukushima nuclear disaster. Background On March 11, 2011, Japan’s Fukushima Prefecture was struck by one of the biggest disasters in recent history. A tsunami, caused by an earthquake in the Pacific, hit the Fukushima Daiichi Power Plant, triggering the meltdown of the nuclear reactors, which led to explosions and radioactive material being released into the atmosphere. In the following days, wind and rain carried the radioactive material inland. More than 25,000 hectares of farmland, in what used to be one of Japan’s most important agricultural regions, were contaminated. The official decontamination method removes the fertile topsoil and replaces it with infertile dirt from the mountains, which produces huge amount of radioactive waste: 16 million m2, stored all over the region. But most importantly: By removing the fertile soil, it makes farming impossible. So even though radiation decreases, the region remains abandoned, because without farming, rural Fukushima communities lose their livelihood. Describe the idea Environmental technology specialists from METER, together with Dr. Masaru Mizoguchi from The University of Tokyo, fellow environmental scientists and the NPO Fukushima Saisei, have developed an innovative sustainable decontamination method for farming: It removes the radioactive material from the soil, without removing the soil itself. The method can be easily applied by farmers themselves, because it uses only available resources. It enables farmers to grow perfectly safe rice on the fields inherited from their ancestors again. And because it removes only the radioactive particles instead of the whole topsoil, it reduces the amount of radioactive waste by 95% compared to the official method. By giving the farmers back their fields, they regain their livelihood. This revitalizes communities and business. The whole region can grow again. What were the key dates in the development process? 1996 First METER environmental sensor installed in Fukushima Prefecture. 2011 03 11 2:46 pm A 9.0 earthquake occurs in the Pacific. 2011 03 11 A tsunami, spawned by an earthquake in the Pacific, hits the Fukushima Daiichi power plant and causes the meltdown of the reactor cores, resulting in explosions and the release of radioactive material into the atmosphere. 2012 01 Proposal of decontamination method core idea by Dr. Masaru Mizoguchi. 2012 07 First team meeting in Iitate, Fukushima Prefecture. 2013 07 Second meeting in Iitate, testing different approaches, several scientific publications. 2014 - 2015 Several visits, refinement of method, long time analysis of soil and rice, several scientific publications. 2016 – 2019 Several visits, scaling to more fields in the region. Describe the innovation/technology At the core of the innovative method is the discovery that radioactive cesium binds to the clay in the rice fields: Remove the clay, and you remove the cesium. The second ‘ingredient’ of the innovation is a physical trick: Clay floats on water. By flooding the fields and stirring up the topsoil, the clay cesium compound rises to the top, from where it can be drained off into a pit next to the field, dried and stored efficiently. A single application removes 80% of the cesium from the soil, while keeping the fertile topsoil needed for farming. The rice grown on these decontaminated fields is regularly tested for radiation and found to be perfectly safe, far below the official limit, which is 10 times stricter than in the U.S. and Europe. Because the method removes only the radioactive cesium and the clay, instead of the whole topsoil, the amount of radioactive waste is reduced by 95% compared to the official method. Farmers bury it in a distance, and because the cesium continues to bind to the clay, it won’t move in the soil and can decay safely. This eliminates the environmental and psychological impact of large nuclear waste storage sites. Describe the expectations/outcome The sustainable decontamination method removes 80% of the cesium in the soil with a single application. It has been applied on many rice fields all over Fukushima Prefecture, by farmers themselves, using available resources. The rice grown on the decontaminated fields is perfectly safe, more than 10 times below the limit of official tests for products from Fukushima Prefecture, which are the strictest radiation tests in the world. Compared with the official decontamination method, the application of the sustainable method reduces radioactive waste by 95%, prevented thousands of cubic meters of radioactive waste. Fukushima farmers regain their livelihood, which brings back communities and economy. The method is being adopted by farmers and organizations in Fukushima and beyond.
