Current research priorities on fog harvesting as a clean water resource: A bibliometric approach

Abstract

By 2050, more than 50% of the world’s population will face water stress. Global demand for drinking water will also increase due to economic development, population growth and other needs. To alleviate this growing problem, the scientific community is called upon to explore all potential water resources and develop appropriate technologies. One such promising resource is fog, especially when climatic conditions are favorable and nearby conventional resources are insufficient. The present bibliometric study is an attempt to explore the topic of “fog harvesting” and understand the dynamics in this area. Indeed, three significant directions have been identified: 1- materials, their properties and characteristics; 2- biological mimicry to collect fog; 3- interaction with other nearby issues (energy, solar, desalination, etc.). In summary, “fog harvesting” is a relatively premature but promising area of research. Due to the strong dependence on climate and topography, this area is still hesitant in terms of collaboration. This may be a good avenue to explore.
