On the Water Front

Revisiting the first OpenET Applications Conference: how satellite-based data is transforming water, farm, and forest management 

By Rachel O'Connor / Published: May 31, 2024

This spring, hundreds of scientists, engineers, water managers, farmers and ranchers gathered in New Mexico to share and learn about how OpenET data is being used to advance water resources management. OpenET has radically improved access to data on evapotranspiration (ET) — or how much water plants and other vegetation consume. The result has been a flood of new applications of ET data in land and water management. 

This year’s convening in New Mexico was a first-ever chance to take stock of all the ways people are using OpenET. The conference cut across a wide range of geographies and sectors and revealed a quickly emerging, dynamic community of practice centered on the platform.  Read More »

Revisiting a centuries-old approach to farming that embraces water scarcity.

By afajardoanstine / Published: December 7, 2023

As discussions at COP28 wrestle with climate impacts on global food and water security, we hear from a Hopi farmer on his thriving practice of dry farming and his hopes for shared learning in Dubai.

______

The arid climate of the Hopi reservation in northeastern Arizona receives a mere 8.5 inches of annual rainfall. For perspective, the yearly United States average is 30 inches. Despite this severe aridity, for over 3,000 years, the Hopi people have stewarded an extraordinary agricultural tradition centered on dry farming.

Dr. Michael Kotutwa Johnson is an Indigenous Resiliency Specialist at the University of Arizona and a leading practitioner of Hopi dry farming — a form of agriculture that eschews irrigation in regions with limited water moisture. As a 250th-generation Hopi dry farmer, his ongoing traditional practices are a  testament to the power of cultural values and the potential of climate-adaptive farming. These ongoing Hopi farming practices defy modern notions of crop needs and vulnerability in areas with limited irrigation and water supply. Read More »

Learning from shared scarcity: the Colorado River, the Yellow River and the world

By Brian Jackson and Yiwei Gan / Published: October 30, 2023

One of the largest rivers in the world struggles to reach the ocean. Spread across a huge slice of a continent, its basin supports millions. Yet the weight of its work to irrigate and power booming farms and cities in an increasingly arid zone is straining the river to a breaking point. For many working in the western water space, this describes the Colorado. A river whose over-work and over-allocation, despite its fundamental role in sustaining life for half a continent, seems in many ways singular.

The Phoenix area can no longer grow on groundwater. What does this mean for Arizona?

By Christopher Kuzdas / Published: June 7, 2023

Last week Governor Hobbs and the Arizona Department of Water Resources (ADWR) released a new analysis of groundwater in the Phoenix metro area. News broke around the country with headlines questioning the viability of future development in the region. But, what does this new analysis actually mean for Arizona? Let’s dive in.

New report: Investing in Arizona’s water future

By Anélyse Regelbrugge / Published: May 16, 2023

This blog is co-authored by Rachel O’Connor, Manager, Climate Resilient Water Systems.

As Arizona’s water crisis worsens due to extreme drought and overuse, more attention than ever is being directed toward addressing this critical issue. At the federal level, an influx of funding has become available through the Bipartisan Infrastructure Law and Inflation Reduction Act. And at the state level, the Water Infrastructure Finance Authority (WIFA) has just begun accepting proposals for its first allocation of $200M for water conservation projects.

While differing ideas abound, it is critical that our finite time and resources are dedicated to a combination of sensible and distributed multi-benefit projects that stand to bring genuine benefits to Arizonans and the environment. Single “silver-bullet” solutions are often unrealistic and obscure potential negative social, economic, and environmental impacts.

To facilitate the conversation, the Water for Arizona Coalition, which includes EDF, has released a new report titled, Investing in Arizona’s Water Future. The report provides a succinct overview of some of the water conservation and augmentation options that have been brought forward including estimates for the water benefit, cost, and time-frame for each option along with additional considerations.
