Global Water Security Center

Providing decision makers with the most reliable, ground-breaking research, applied scientific techniques, and best practices so that the hydrologic cycle and its potential impacts can be put in a context for appropriate action and response by the United States

I’m in Washington, DC, this week to help share more about how our work supports and improves our national water security capabilities. I was pleased to learn that Rebecca Zimmerman, the Acting Principal Deputy Assistant Secretary of Defense for Homeland Defense and Hemispheric Affairs, referenced GWSC in her recent testimony to the House Armed Services Committee.

As I visit various offices in the nation’s capital, I can’t help but take a moment to be grateful for the tremendous partnerships GWSC has been able to develop in the past couple of years.

I won’t start naming specific people or organizations for fear of leaving someone out, but if you have contacted us, supported us, or worked with us, please know that you have my sincerest thanks. We couldn’t do this work without you.

As I ponder the state of water security in this first quarter of 2024, I can’t help but marvel at how far we’ve come – while keeping an eye on how far we have to go.  

I attended the first “Integrating Climate Change into Professional Military Education” conference last month in Stockholm and had the opportunity to engage with brilliant leaders from around the world around issues at the intersection of water, food, energy, and health. For the first time, water was included in the final resolution at last year’s COP27 and continued to play a major role this year. Even both major parties of the US government seem to agree on the importance of water to our national security strategy.  

At the same time, there’s progress to be made, and that’s where the Global Water Security Center comes in. We are bridging the gap between the people who are “doing” the science and those who are making decisions about national security. We are supporting the development of new, improved data sets and algorithms and providing the essential contextual translation of that information to make it useful for decision makers. 

You can read more of my thoughts on the state of water security in my recent blog post, and if you’re interested in working with us, you can now submit an RFI on our website.

Happy New Year!

The Global Water Security Center finished 2023 strong, and we’re looking forward to a great 2024. You can read more about our work last year in our 2023 annual report. Some highlights include the creation of 21 Quicklooks and country insight briefs; four new hires, more than doubling our staff size; and $6.2 million in federal funding for 2022-23. Our new staffers included three dedicated data scientists.

We anticipate bringing in three additional staff members in the first quarter of 2024, allowing us to increase our capabilities even further. To keep our partners, stakeholders, and other interested parties informed, I will send out monthly emails like this to share the latest news from GWSC.

As always, I welcome your insight and feedback. Wishing you and yours a great 2024!
