As this photographer struggles to convey the sheer immensity of removing one thousand acres of almond trees, her commenters make some helpful points.
An article on local resistance to measuring individual wells. That resistance needs some counterweights. I can think of two. First, a per-acre assessment for the costs of subsidence due to overdraft. Any farmer who wants to demonstrate, based on pumping records, that his or her assessment should be lower is welcome to switch to an assessment based on metered pumping. Second, a moratorium on permanent crops in basins with declining groundwater levels. Putting either or both of those in place would change the incentives for growers considerably. Neither requires measuring pumping well-by-well, but you’d shortly have growers requesting well metering and groundwater monitoring.
