 note = {In the disaster-affected area of Fukushima, farming on consolidated rice paddy fields and protected horticulture areas has recommenced. This is in order to prevent the risk of harmful rumors. The farmers commute from a far distant refuge since the evacuation order has been lifted. In addition, their greenhouses and arable lands are often scattered. This has made it difficult for them to visit their production sites frequently, although some farmers have started to plant new cash crops as farming has restarted.
In order to manage this situation, it would be helpful for such farmers to obtain agricultural information without physically visiting the farmland. This would require an inexpensive remote monitoring system which could be easily introduced and adapted according to the farmer’s needs, to provide agricultural information or cultivation history. Commercially available remote monitoring systems are designed to be used throughout the year and are relatively expensive for short-term use, such as during the seedling growth
period. Therefore, we devised a remote monitoring system named the “Kayoinougyo Shien system” after the word “Kayoinougyo” that the farmers who commute from their place of refuge or residences far from their farms to the area where farming has restarted.
The new technology is based on a commercial IoT prototyping kit with Web API and a messaging application. We demonstrated its capability and usefulness in the greenhouse in the regenerated area of farming in Fukushima. In this study, we evaluated the practicality and effectiveness of the system by adding the functions of data statistics and graphic data notification, and providing data on temperature, humidity, soil moisture content, and photographs taken by IoT camera, to meet the needs of the farmers. The accuracy of the temperature sensor was within ± 1 °C. The error rate of the data notification was less than 1% during the test period. The farmers were able to determine what needed to be done; whether to open the windows of their greenhouses or not, or irrigate their crops, by obtaining data at the required intervals and utilizing it in cultivation. Therefore, we were able to confirm the practicality and effectiveness of this system., 福島県の被災地域では大規模水稲生産法人のほか，風評被害を受けにくいハウス農家を中心に営農再開している．生産者は避難に伴う転居先から生産現場まで距離がある「通い農業」の状態にあり，加えてハウスや耕地が分散していることが多いため，生産現場を頻繁に訪れることが難しい．一方，生産者は情勢の変化に応じて新しい換金作物への取り組みも始めている．このような実状に対応するため，営農形態の変化に応じた柔軟性のある遠隔監視システムが求められている．しかし，市販の遠隔監視システムは通年での契約を想定しており，育苗期間など短期利用には高価である．
そこで，我々はWeb API を有する市販IoT プロトタイピング・キットとメッセージングアプリによるハウス遠隔監視システム「通い農業支援システム」を考案し，営農再開地域のハウスで多くの作物に対して実用試験を行った．本システムは温度，湿度，土壌水分，画像データ等に加えて，取得データの統計値やグラフを通知でき，データ通知のエラー率1% 未満，温度の精度約± 1 ℃で運用できた．また，生産者が必要な間隔でデータを得て遠隔地の管理作業の要否を判断できるなど，実用性・有効性を確認した．, 6章: 営農再開に向けた施設園芸の復興支援  /原著論文
