The Ag Irrigation Conservation Paradox

Ever surprising. Although increased irrigation efficiency is one of the most widely promoted solutions to increased water demand, its actual effects on the water balance are complex and even paradoxical. The cost to farmers of delivered irrigation water is minimal, meaning that there is little benefit from installing expensive water-conservation technology in terms of reducing …

There was simply too …
