Mapping of scientific production on actions, projects and challenges to deal with fresh water scarcity

Abstract

The concern over water is due to the increase in population, which has led to an increase in water consumption. Given the context of water scarcity, it is necessary to direct efforts towards preventing this occurrence. One way to meet demand is through technology for water reuse. In this sense, the research proposal was to conduct a systematic and integrative review of the literature on technology transfer related to water, with a focus on water reuse. A total of 33 articles on the subject were selected. The main findings were that research is focused on promoting water reuse and addressing concerns about water consumption. The research highlights the importance of public policies related to water consumption and reuse, as well as the need to understand the population's awareness and acceptance of such aspects. One alternative to meet the water scarcity crisis is through desalination, but progress is needed to overcome the barrier of high energy consumption and waste generation. Regarding technology transfer, sharing knowledge on a global level is necessary for effective technology transfer and satisfactory results.
