Freshwater consumption and demand have, spiralled over the years, due to population growth, agricultural and industrial intensification. Innovative water conservation techniques (greywater reuse, rainwater harvesting, seawater desalination and ground water extraction, etc.), especially in the face of climate change and climate variability are central in minimizing water shortages, hunger and poverty alleviation, as well as health challenges. Most of water conservation methods remain ineffective and less adoption, due to associated costs, inaccessibility and technical expertise in addressing water challenges, particularly in developing countries. Greywater reuse, which approximately represents 43–70% of the total domestic wastewater volume remains as the alternative and effective source of water that can help reduce pressure on freshwater for food production and poverty alleviation in in third-world countries. Great research strides have been demonstrated on greywater reuse for agricultural use, but much remains unknown with regard to adoption rates, especially in developing countries. This work provides a detailed review on greywater reuse in crop production with particular emphasis on and community perceptions, challe...
