Efficient irrigation may produce more crops, but it doesn’t appear to preserve groundwater, according to a federal report released this week. Decades of irrigation has already depleted aquifers that many irrigated farms rely on, according to the report from the Government Accountability Office, and efficient systems appear to not help. Minus a few exceptions, GAO researchers found “there is no change in the amount of water farmers apply to a field with more efficient technology,” according to the Nov. 12 report.
