How can irrigation efficiency systems be technologically improved for sustainable agriculture?

In a country like Bangladesh, where there are lots of people and the climate is changing, there’s a big problem with having enough water. Water is super important for growing food, but if it’s not used carefully, there might not be enough for everyone. The challenge is to use water in the best way possible for farming. This means making sure that the crops get just the right amount of water at just the right time. If farmers can do this, they can grow more food without wasting water. This is really important because it helps make sure that there’s enough water for both people and farms, even when there’s not a lot of rain or when it’s really hot and dry. So, the big task is to figure out how to use water in a smart way that helps grow lots of food but also saves as much water as possible.
