As climate change and agriculture burden water resources globally, there is a need for more efficient water use including irrigation with recycled water in greenhouses. While research has proven that properly treated recycled water can be safe for use, many growers still express concern. Underlying most studies on growers' perceptions is the assumption that they understand recycled water the same way scholars and policy makers do—as municipally treated wastewater. We question this assumption and explore whether the ways in which growers conceptualize recycled water is associated with the ways they perceive its usability. Our findings reveal that growers define recycled water in four different ways—captured water, treated water, recirculation and in a general sense as ‘reuse’. These definitions do appear to suggest trends in the way recycled water is perceived by growers. While these definitions do not significantly affect growers' willingness to use, other factors such as prior experience using recycled water appear to be significant.

什么是循环水？调查温室种植者使用循环水的定义、看法和意愿

由于气候变化和农业对全球水资源造成负担，因此需要更有效地利用水资源，包括在温室中使用再生水进行灌溉。虽然研究证明经过适当处理的再生水可以安全使用，但许多种植者仍然表示担忧。大多数关于种植者看法的研究的基础是假设他们以与学者和政策制定者相同的方式理解再生水——就像市政处理的废水一样。我们质疑这一假设，并探索种植者将循环水概念化的方式是否与他们感知其可用性的方式有关。我们的研究结果表明，种植者以四种不同的方式定义循环水——捕获的水、处理过的水、再循环以及一般意义上的“再利用”。这些定义似乎表明了种植者对再生水的看法的趋势。虽然这些定义不会显着影响种植者的使用意愿，但其他因素（例如使用循环水的先前经验）似乎很重要。
