The article discusses how using less water for irrigation (DI) can help improve crop yields and water productivity in Ethiopia. The researchers reviewed various studies and found that applying deficit irrigation can increase water productivity compared to full watering. While some crops had slightly lower yields with deficit irrigation, the benefits of using less water for more land outweighed this reduction. Techniques like alternate furrow irrigation can also help save water. Overall, using deficit irrigation methods can enhance sustainable crop and water productivity, which is essential for feeding a growing population in Ethiopia facing limited water resources.
