I don’t know if Pakistan is quite comparable with Romania on the healthy and happy metrics, but the real efficiency comparison is between Pakistani and Indian Punjabs on groundwater depletion and tube wells. Indian Punjab may be better at getting the groundwater out and irrigation intensity but at what cost to the aquifer? (This is not saying Pak doesn’t need to move away from wasteful canals and build water storage for rain - they do)

I was only using Pakistan and Romania since they were in the original example. The important bit was to not optimize a proxy for a thing without recognizing that it's a proxy and may lead to undesirable conclusions or actions.
