Water scarcity is one of the global issues due to climate change, affecting arid and semi-arid regions, and transforming irrigated areas into rainfed ones. It is one of the principal ecological constraints that hinder agriculture?s sustainability. Now, researchers have introduced a new water-holding amendment i.e. hydrogel polymer, which constitutes a group of polymeric materials and a hydrophilic structure that renders them capable of holding large amounts of water in their three-dimensional networks. It is a new approach to water management that can absorb and retain a huge amount of moisture under plentiful rainfall and irrigation events and release it back to the soil to mitigate crop water demand when the rhizosphere zone dries up under drought conditions. Therefore, hydrogel may prove to be a practical and advantageous solution for enhancing agricultural productivity during times of water scarcity.
