Using the Receptivity model to uncover 'urine blindness': perceptions on the re-use of urine

Population growth, climatic changes and over-exploitation of natural resources are at the basis of the world’s food crisis, which counts almost one million people without sufficient food sustenance. These changes require novel environmental practices which are based on nutrient recovery and management in agriculture. This contribution analyses and discusses users’ perceptions on re-use of urine as fertilizer through the lenses of the Receptivity model. A search was performed on Scopus (as well as other web search engines) using the keywords: urine, nutrient recovery and sanitation. Results shows how questions related to awareness, association, acquisition and application of the environmental change can represent hurdles to novel models of nutrient recovery and the use of urine in agriculture. Examples of hurdles identified from the literature relate to poor understanding of potential for urine reuse, social stigma attached to using dry sanitation and applying urine in agriculture and poor operational knowledge of application of urine in agriculture. Conclusion relates to the illustration of implications of such challenges on the design of environmental interventions
