６６：IWRM実践の障害（成功の根拠）

前回に引き続きIWRM実践の障害の第２番目である。これまでgood practices事例の紹介は多いがなぜ成功したかの根拠が薄く乏しい。。この点に着目してIWRM実践の難しさをジェフレイ教授らは示している。

Evidence of success barrier

The necessity of adapting the IWRM concept to suit different local contexts does not allow for a generic, complete description of strategies and techniques. In practice, the IWRM concept has not structurally demonstrated its ability to increase the sustainability of water resources management. Empirical evidence is either missing or poorly reported. It will be important to identify the essential elements for IWRM, while avoiding rigid prescriptions and allowing for vast differences among countries.

Research agenda

How can evidence be gathered to show that management frameworks like IWRM are successful? Gathering evidence to show the value of implementing these approaches may be a necessary prerequisite to convincing political leaders to instigate institutional and governance reform. However, existing evidence is not gathered easily.

多くの事例を収集・分析し、IWRM実践の難しさを整理し・分類し、主要な構成要素を抽出し、その上でIWRM問題の解決手法を提示することが必要だ。総論から各論にアプローチする手法はどうも実践的ではなさそうである。

次回はIWRM定義のあいまいさという障害について。
