Conservation credits: Payments for voluntary groundwater conservation

  • Paying farmers to pump less groundwater could be a cost-effective and equitable way to reduce water and electricity consumption in irrigated agriculture.

  • Results suggest that financial incentives may be able to substantially reduce groundwater pumping — but the range of uncertainty is large.
  • A larger evaluation could reliably measure the cost-effectiveness of conservation payments
