Effective utilization of waste water through recycling, reuse, and remediation for sustainable agriculture

Water is vital for human, animal, and plant life. Water is one of the most essential inputs for the production of crops. Plants need it in enormous quantities continuously during their life. The role of water is felt everywhere; its scarcity causes droughts and famines, its excess causes floods and deluge. During the next two decades, water will increasingly be considered a critical resource for the future survival of the arid and semiarid countries. The requirement of water is increasing day by day due to intensive agriculture practices, urbanization, population growth, industrialization, domestic use, and other uses. On the other hand, the availability of water resources is declining and the existing water is not enough to meet the needs. To overcome this problem, one available solution is utilization of waste water by using recycling, reuse, and remediation process.
