On the Water Front

Welcome to the first edition of On the Water Front, the new blog and newsletter of EDF’s Water Program

World Water Day Groundwater Image

Welcome to the new monthly e-newsletter from EDF’s Climate Resilient Water Systems team. It seemed fitting to launch this effort on World Water Day because the theme this year aligns so closely with our work: “Groundwater  Making the Invisible, Visible.”  

Over these past two challenging years, the pandemic, my own health issues and family needs have highlighted some major flaws in our health care system that reminded me of … groundwater. When a crisis arrives, our response can be quick, aggressive and sometimes even highly effective. This same system isn’t as good at long-term health — supporting the patient in their ongoing well-being, anticipating possible or even likely future conditions, and taking actions in advance to avoid a crisis.

I see a similar pattern in how we manage our groundwater. When there’s an obvious crisis from groundwater depletion (wells going dry, land subsidence or saltwater intrusion, for instance), we jump to action, attempting to treat a long-declining patient with a single surgical procedure. Sure, we need these procedures, but often we do them without the support of the whole health care system.

Crop-switching in the megadrought: Can guayule help Arizona farmers use less water?

Guayule and ladybugs

This year, farmers in Pinal County, Arizona, will lose two-thirds of their irrigation water from the Colorado River because of a historic shortage declaration triggered by the driest period in more than 1,000 years. And within two years, they will be completely cut off from the Colorado River.

Some farmers are responding by fallowing fields. Others are selling their land to solar companies. And then there’s Will Thelander, a farmer who partnered with EDF, Bridgestone Americas and the University of Arizona to test a new crop that uses half as much water as the alfalfa he previously grew.

Crop-switching to a desert shrub called guayule used to produce rubber is one of just many strategies that will be needed in Arizona and other regions to adapt to water scarcity and maintain agricultural economies in a new era of aridification. However, it’s not nearly as simple as just planting different seeds in the ground.
