Due to climate change, it is estimated that at least a quarter of the world's population will be affected by water scarcity in the coming years and if urgent action is not taken, the global water deficit will be 40% by 2030. To overcome water scarcity, 15 million cubic meters of untreated wastewater are used daily globally to irrigate agricultural crops, contaminating the soil with pathogens, heavy metals and excess salts. It is estimated that to meet food demand by 2050, the water available for agricultural irrigation must increase by 70%. In this context, wastewater can become a suitable water source to meet this growing demand. Since 10% of the world's population consumes food from crops irrigated with wastewater, the reuse and recycling of treated wastewater is a sustainable approach to meet the growing demand for clean water and ensure its availability for current and future generations. Treated wastewater is both a resource and a challenge. Although it may be rich in nutrients and can increase agricultural production while simultaneously reusing resources and protecting the environment, high treatment costs, public acceptance, and pollution risks limit its use. If properly managed, the reuse of treated wastewater has enormous potential to alleviate water scarcity and promote sustainable agriculture as well as global food security. The aim of this paper is to shed light on the importance of using treated wastewater in irrigation as an alternative freshwater source.
