Abstract

Paddy field dams are one of the nature-based solutions provided by farmers in Japan for mitigating flood damage. This scoping review analysed 38 papers in the Web of Science Core Collection and J-STAGE obtained by searching for keywords associated with paddy field dams. Among the 38 selected papers, 31 (approximately 80%) examined the effects of paddy field dams. Knowledge of the effects of paddy field dams, under what conditions, to what extent, how much and what kinds of effects are observed is needed. Studies have revealed that an external force that is too large will cause overflow of water, rendering paddy field dams ineffective. Therefore, it is essential to raise and maintain the ridges of paddy fields. However, no studies have focused on the effects of paddy field dams on crops. The external validity of disseminating paddy field dams is not assured because of bias toward cases in specific regions, and a universal dissemination method for paddy field dams has not been identified. No studies have examined the effectiveness of paddy field dams compared with alternatives or the prioritization of paddy field dams.

日本水田坝研究范围综述

稻田水坝是日本农民为减轻洪水破坏而提供的基于自然的解决方案之一。本文通过搜索与水田坝相关的关键词，分析了Web of Science Core Collection和J-STAGE中的38篇论文。在38篇入选论文中，31篇（约80%）研究了水田坝的影响。需要了解水田坝的影响，在什么条件下，在多大程度上，观察到多少影响和什么样的影响。研究表明，外力过大会导致水田坝溢流，使水田坝失效。因此，提高和保持水田的垄沟是必不可少的。然而，目前还没有关于水田坝对农作物影响的研究。由于对特定地区案例的偏向，水田坝推广的外部有效性不能得到保证，也没有确定一种普遍的水田坝推广方法。没有研究将水田坝与其他选择或水田坝的优先次序进行比较。

期刊介绍： Human intervention in the control of water for sustainable agricultural development involves the application of technology and management approaches to: (i) provide the appropriate quantities of water when it is needed by the crops, (ii) prevent salinisation and water-logging of the root zone, (iii) protect land from flooding, and (iv) maximise the beneficial use of water by appropriate allocation, conservation and reuse. All this has to be achieved within a framework of economic, social and environmental constraints. The Journal, therefore, covers a wide range of subjects, advancement in which, through high quality papers in the Journal, will make a significant contribution to the enormous task of satisfying the needs of the world’s ever-increasing population. The Journal also publishes book reviews.
