Fukushima Reborn


Fukushima reborn

Near the Fukushima disaster site, scientists and citizens work tirelessly to clean radiation from affected farmland soils. Each weekend, they travel to a small village near Fukushima and labor to rehabilitate the land. Under the guidance of Dr. Masaru Mizoguchi, their efforts have rid the rice fields of the radioactive isotope cesium 137, making the rice harvested there safe for human consumption.

The fight for a better future

The fight for a better future

But what will happen to the contaminated soil surrounding the decontaminated area? Will it settle in nearby stream beds, eventually contaminating the rice paddies?


Using multi-parameter METER environmental sensors such as the ATMOS 41 all-in-one weather station, TEROS 12 soil moisture sensors, and TEROS 21 water potential sensors, Dr. Christian Renschler, Dr. Masaru Mizoguchi, and the Non Political Organization will monitor 17 environmental variables across the landscape. The scientists will use this information to try and predict runoff. ZENTRA Cloud gives them the ability to see meteorological data, soil water content, and water potential data simultaneously graphed in near-real time, enabling them to understand the larger picture much faster.

Data management is now a breeze

Without cloud-based data delivery, the team would be forced to traverse difficult, remote terrain every three months to physically download data. And that data may be suspect if technical issues crop up during their absences. ZENTRA Cloud enables the team to obtain their data hourly with almost no effort, and avoid impossible regular treks to extremely steep, remote hillslope sites.

We developed a method to decontaminate the soil while leaving it fertile. Using only resources and processes already present in rice farming.

Connect everything, and everyone

Near-real-time data and remote device management means Dr. Renschler, a visiting professor, can easily check for and manage problems from the comfort of his office, even though he lives halfway around the world in Buffalo, New York. Streamlined data sharing lets him discuss and brainstorm issues, as they happen, with other collaborators who live scattered across the globe.


The scientists will gather environmental data and enter the information into erosion models and water balances to predict the fate of the water and the radioactive soil as it moves around in these watersheds. ZENTRA Cloud facilitates better and faster soil moisture, precipitation, and evaporation information and data sharing so the scientists can more quickly determine what might happen, enabling them to predict and prevent possible future environmental problems.
