Desalination and its challenges
Desalination is an option for reducing water stress that has advanced spectacularly. It is a process that faces the challenges of reducing costs, avoiding gas emissions, and solving the polluting problems of brine, its main waste product. It can be an option for developing countries, provided its suitability is evaluated, the technological gap is eliminated with the appropriate alliances, and public-private collaboration is adopted as a fair and effective model.
