Alternate Wetting and Drying (AWD) is an innovative irrigation technique aimed at enhancing the sustainability and efficiency of rice cultivation. This method involves alternating periods of flooding and drying in rice fields, significantly reducing water usage by 20–50% and methane emissions by 30–50%. AWD improves soil health by promoting aeration, which enhances root development and microbial activity, leading to healthier plants with deeper root systems. The economic benefits include cost savings from reduced water and energy usage, stable or improved crop yields, and increased economic sustainability for farmers. However, the adoption of AWD faces challenges such as soil type limitations, water management complexities, and farmer skepticism. Addressing these challenges requires strategic interventions, including demonstration plots, financial incentives, comprehensive training, and effective extension services. Government policies, supportive regulations, and international collaboration are crucial for facilitating AWD adoption. Integrating AWD with other sustainable agricultural practices, such as conservation agriculture and integrated nutrient management, can amplify its benefits. Further research is needed to optimize AWD protocols for various soil types and climatic conditions, expand its application to different crops, and develop advanced monitoring technologies. By addressing these challenges and leveraging support from policies, research, and training, AWD can be advanced as a key climate-smart agricultural practice globally, promoting a more sustainable and resilient agricultural future.
