Vietnam's Water-Saving Secret: Lasers in Rice Fields

Water is a big deal in Vietnam, especially for farmers. A new study in the Mekong Delta shows laser land leveling (LLL) can save a lot of water. Farmers using LLL can save up to 20% more water compared to traditional methods. That’s like having more water for everyone! But is it all sunshine and rainbows? Not quite. Farmers often use their own experience to operate these lasers, which might cause issues in the long run. The study found that if only 5% of farmers started using this method, Vietnam could save millions of cubic meters of water. That’s a lot of water! Policymakers also have a big role to play here. Promoting this tech could help Vietnam deal with climate change and water shortages. It’s like a win-win situation! The study highlights how important it is to look closely at how new technologies can improve water usage in farming.
