Water is the other US-Mexico border crisis, and the supply crunch is getting worse
The U.S.-Mexico border is facing a severe water crisis exacerbated by climate change, increased demand, and pollution. Collaborative governance is essential to address these growing challenges effectively.

Immigration and border security will be the likely focus of U.S.-Mexico relations under the new Trump administration. But there also is a growing water crisis along the U.S.–Mexico border that affects tens of millions of people on both sides, and it can only be managed if the two governments work together.
Climate change is shrinking surface and groundwater supplies in the southwestern U.S. Higher air temperatures are increasing evaporation rates from rivers and streams and intensifying drought. Mexico is also experiencing multiyear droughts and heat waves.
Growing water use is already overtaxing limited supplies from nearly all of the region’s cross-border rivers, streams and aquifers. Many of these sources are contaminated with agricultural pollutants, untreated waste and other substances, further reducing the usability of available water.
As Texas-based scholars who study the legal and scientific aspects of water policy, we know that communities, farms and businesses in both countries rely on these scarce water supplies. In our view, water conditions on the border have changed so much that the current legal framework for managing them is inadequate.
Unless both nations recognize this fact, we believe that water problems in the region are likely to worsen, and supplies may never recover to levels seen as recently as the 1950s. Although the U.S. and Mexico have moved to address these concerns by updating the 1944 water treaty, these steps are not long-term solutions.
Growing demand, shrinking supply
The U.S.-Mexico border region is mostly arid, with water coming from a few rivers and an unknown amount of groundwater. The main rivers that cross the border are the Colorado and the Rio Grande – two of the most water-stressed systems in the world.
The Colorado River provides water to more than 44 million people, including seven U.S. and two Mexican states, 29 Indian tribes and 5.5 million acres of farmland. Only about 10% of its total flow reaches Mexico. The river once emptied into the Gulf of California, but now so much water is withdrawn along its course that since the 1960s it typically peters out in the desert.
The Rio Grande supplies water to roughly 15 million people, including 22 Indian tribes, three U.S. and four Mexican states and 2.8 million irrigated acres. It forms the 1,250-mile (2,000-kilometer) Texas-Mexico border, winding from El Paso in the west to the Gulf of Mexico in the east.
Other rivers that cross the border include the Tijuana, San Pedro, Santa Cruz, New and Gila. These are all significantly smaller and have less economic impact than the Colorado and the Rio Grande.
At least 28 aquifers – underground rock formations that contain water – also traverse the border. With a few exceptions, very little information on these shared resources exists. One thing that is known is that many of them are severely overtapped and contaminated.
Nonetheless, reliance on aquifers is growing as surface water supplies dwindle. Some 80% of groundwater used in the border region goes to agriculture. The rest is used by farmers and industries, such as automotive and appliance manufacturers.
Over 10 million people in 30 cities and communities throughout the border region rely on groundwater for domestic use. Many communities, including Ciudad Juarez; the sister cities of Nogales in both Arizona and Sonora; and the sister cities of Columbus in New Mexico and Puerto Palomas in Chihuahua, get all or most of their fresh water from these aquifers.
A booming region
About 30 million people live within 100 miles (160 kilometers) of the border on both sides. Over the next 30 years, that figure is expected to double.
Municipal and industrial water use throughout the region is also expected to increase. In Texas’ lower Rio Grande Valley, municipal use alone could more than double by 2040.
At the same time, as climate change continues to worsen, scientists project that snowmelt will decrease and evaporation rates will increase. The Colorado River’s baseflow – the portion of its volume that comes from groundwater, rather than from rain and snow – may decline by nearly 30% in the next 30 years.
Precipitation patterns across the region are projected to be uncertain and erratic for the foreseeable future. This trend will fuel more extreme weather events, such as droughts and floods, which could cause widespread harm to crops, industrial activity, human health and the environment.
Further stress comes from growth and development. Both the Colorado River and Rio Grande are tainted by pollutants from agricultural, municipal and industrial sources. Cities on both sides of the border, especially on the Mexican side, have a long history of dumping untreated sewage into the Rio Grande. Of the 55 water treatment plants located along the border, 80% reported ongoing maintenance, capacity and operating problems as of 2019.
Drought across the border region is already stoking domestic and bilateral tensions. Competing water users are struggling to meet their needs, and the U.S. and Mexico are straining to comply with treaty obligations for sharing water.
Cross-border water politics
Mexico and the United States manage water allocations in the border region mainly under two treaties: a 1906 agreement focused on the Upper Rio Grande Basin and a 1944 treaty covering the Colorado River and Lower Rio Grande.
Under the 1906 treaty, the U.S. is obligated to deliver 60,000 acre-feet of water to Mexico where the Rio Grande reaches the border. This target may be reduced during droughts, which have occurred frequently in recent decades. An acre-foot is enough water to flood an acre of land 1 foot deep – about 325,000 gallons (1.2 million liters).
Allocations under the 1944 treaty are more complicated. The U.S. is required to deliver 1.5 million acre-feet of Colorado River water to Mexico at the border – but as with the 1906 treaty, reductions are allowed in cases of extraordinary drought.
Until the mid-2010s, the U.S. met its full obligation each year. Since then, however, regional drought and climate change have severely reduced the Colorado River’s flow, requiring substantial allocation reductions for both the U.S. and Mexico.
In 2025, states in the U.S. section of the lower Colorado River basin will see a reduction of over 1 million acre-feet from prior years. Mexico’s allocation will decline by approximately 280,500 acre-feet under the 1944 treaty.
This agreement provides each nation with designated fractions of flows from the Lower Rio Grande and specific tributaries. Regardless of water availability or climatic conditions, Mexico also is required to deliver to the U.S. a minimum of 1,750,000 acre-feet of water from six named tributaries, averaged over five-year cycles. If Mexico falls short in one cycle, it can make up the deficit in the next five-year cycle, but cannot delay repayment further. https://www.youtube.com/embed/IgWSMgg9TmE?wmode=transparent&start=0 The U.S. and Mexico are struggling to share a shrinking water supply in the border region.
Since the 1990s, extraordinary droughts have caused Mexico to miss its delivery obligations three times. Although Mexico repaid its water debts in subsequent cycles, these shortfalls raised diplomatic tensions that led to last-minute negotiations and large-scale water transfers from Mexico to the U.S.
Mexican farmers in Lower Rio Grande irrigation districts who had to shoulder these cuts felt betrayed. In 2020, they protested, confronting federal soldiers and temporarily seizing control of a dam.
U.S. President Donald Trump and Mexican President Claudia Scheinbaum clearly appreciate the political and economic importance of the border region. But if water scarcity worsens, it could supplant other border priorities.
In our view, the best way to prevent this would be for the two countries to recognize that conditions are deteriorating and update the existing cross-border governance regime so that it reflects today’s new water realities.

Is College Worth It? New U.S. News Rankings Put More Weight on What Graduates Earn
Is college worth it? MIT has taken the No. 1 spot in the 2027 U.S. News Best Colleges rankings, ending Princeton’s 15-year run. But a new Earnings by Major metric could be even more important for families asking whether college is worth the investment.
For millions of students and families, choosing a college increasingly comes down to a basic question: Is college worth it?
The latest U.S. News & World Report Best Colleges rankings are attempting to provide another piece of information to help answer that question.
The 2027 rankings place the Massachusetts Institute of Technology (MIT) at No. 1 among National Universities, ending Princeton University’s 15-year run at the top. But perhaps the bigger story for prospective students isn’t which university occupies the No. 1 position.
It’s a significant change in how U.S. News measures the value of attending college.
For the first time, the rankings include an Earnings by Major factor designed to examine what graduates earn after leaving school — and to compare those earnings with graduates who studied the same subjects elsewhere.
Is College Worth It? U.S. News Looks Beyond Graduation
College has traditionally been promoted as an investment in a person’s future. But as families confront tuition, housing expenses and the possibility of student debt, simply earning a degree may no longer be enough information when deciding where — or whether — to attend.
Students increasingly want to know what happens after graduation.
The new U.S. News Earnings by Major metric examines graduate earnings four years after graduation using data from the U.S. Department of Education’s College Scorecard.
Importantly, the system doesn’t simply compare the average salary of graduates from one university with another.
Instead, earnings are compared within specific academic disciplines.
That distinction matters.
A university graduating large numbers of engineers, computer scientists or students entering other relatively high-paying occupations could otherwise appear to produce stronger financial outcomes simply because of the subjects its students choose to study.
Comparing graduates within similar fields is intended to provide a clearer picture of how graduates from different institutions fare financially.
From Student Debt to Graduate Earnings
The new Earnings by Major metric replaces the Graduate Indebtedness factor previously used by U.S. News.
That represents an important shift in perspective.
Instead of focusing primarily on how much debt students accumulate, the new measure looks at one aspect of what students may receive financially from their education after entering the workforce.
The metric examines employed federal financial aid recipients whose highest degree is a bachelor’s degree.
According to U.S. News, the approach is intended to reduce the influence of family financial advantages and provide a better indication of the economic value institutions may contribute to graduates.
That doesn’t mean earnings alone determine whether a college education is worthwhile.
But for a student potentially investing tens of thousands of dollars — and several years of their life — knowing how graduates in a particular major perform economically can be an important part of the decision.
MIT Takes the No. 1 Spot
Against that changing methodology, MIT moved into the No. 1 position among National Universities in the 2027 rankings.
The top three are:
- Massachusetts Institute of Technology
- Princeton University
- Harvard University
Princeton’s move to second place ends a run at No. 1 that began with the 2012 edition of the rankings.
Among National Liberal Arts Colleges, Williams College remained No. 1, followed by Amherst College at No. 2. Bowdoin College, Claremont McKenna College, Pomona College and Swarthmore College tied for third.
Nearly 1,700 institutions were evaluated in the 2027 edition.
Outcomes Are Becoming a Bigger Part of the Equation
The addition of graduate earnings is part of a broader emphasis on student outcomes in the U.S. News methodology.
U.S. News says outcomes now account for more than half of a school’s total score.
Institutions can be evaluated using as many as 17 weighted measures, including graduation and retention rates, social mobility for lower-income students, post-graduate earnings, faculty resources and academic peer assessments.
The shift reflects a changing conversation surrounding higher education.
For generations, students were often encouraged to focus heavily on getting into the most prestigious college possible. Today’s students may also be asking more practical questions:
How much will it cost?
How much financial aid will I receive?
How much debt might I have when I graduate?
What do graduates in my intended major earn?
And perhaps most importantly:
Will the investment pay off for me?
College Value Isn’t Just About Salary
Graduate earnings can provide useful information, but salary shouldn’t be treated as the sole measurement of the value of higher education.
Different careers have dramatically different compensation structures.
A graduate pursuing teaching, public service, social work, the arts or nonprofit work may earn less than someone entering engineering, finance or technology while still considering their education worthwhile.
There are also benefits of higher education that are difficult to capture in a salary statistic.
That’s why students comparing schools may want to look beyond an institution’s overall ranking and examine factors such as net price after financial aid, scholarships, graduation rates, student debt, internship opportunities, career placement, location and the strength of the program they actually intend to study.
The best-known university isn’t automatically the best financial or educational choice for every student.
Economic Diversity Also Gets Attention
The 2027 rankings also highlight economic diversity among highly ranked institutions.
According to U.S. News, MIT and Princeton rank third and fourth, respectively, among the top 25 National Universities in the percentage of students receiving federal Pell Grants.
Pell Grants generally assist undergraduate students with significant financial need and typically do not have to be repaid.
Among the top 25 National Liberal Arts Colleges, Amherst College ranked highest for economic diversity under the U.S. News measure.
A New Ranking Looks at In-State Value
U.S. News is also placing additional attention on affordability for students considering public universities.
The 2027 edition introduces a Best Value Schools for In-State Students ranking, which evaluates public universities based on academic quality and affordability for residents.
The University of North Carolina at Chapel Hill took the No. 1 position in the inaugural ranking.
That category could be particularly relevant to families deciding whether the prestige associated with attending a private or out-of-state university justifies potentially higher costs compared with attending a public institution in their home state.
The Rankings Look Different This Year
There is another important caveat when comparing the 2027 results with previous years.
Changes to the Carnegie Classification framework resulted in approximately 20% of previously ranked institutions moving into different U.S. News categories.
Because some colleges are now being compared against different groups of institutions, their 2027 rankings may not be directly comparable with previous years.
The changes also expanded eligibility, allowing additional institutions specializing in areas such as engineering, business and health to enter the rankings.
U.S. News also introduced an undergraduate economics specialty ranking while continuing rankings covering areas such as social mobility, innovation, historically Black colleges and universities, artificial intelligence programs, internships, undergraduate research and study-abroad opportunities.
Public Universities, HBCUs and Social Mobility
Among public National Universities, the University of California, Berkeley and UCLA tied for the No. 1 position, followed by the University of Michigan–Ann Arbor.
The top three Historically Black Colleges and Universities were:
- Spelman College
- Howard University
- Tuskegee University
For social mobility among National Universities, Florida International University and the University of California, Riverside tied for No. 1, with Oakland City University ranked third.
These categories illustrate another reason students may want to look deeper than a school’s overall national position. Different rankings can reveal institutions performing particularly well in areas that may matter more to an individual student.
So, Is College Worth It?
There isn’t one answer that applies to every student.
The cost of attending, financial aid, chosen major, career goals, likelihood of graduating and potential debt can dramatically change the financial equation.
A college with a famous name and high national ranking could be a poor financial choice for one student while a less prominent public university with generous financial aid could be an excellent investment for another.
That’s what makes the addition of Earnings by Major noteworthy.
Instead of asking only “Which college ranks highest?”, prospective students now have another reason to ask a much more personal question:
“What am I paying for — and what could I realistically get in return?”
MIT replacing Princeton at No. 1 makes the headline.
But for students and parents trying to decide whether college is worth the cost, the growing emphasis on outcomes, affordability and post-graduation earnings may ultimately be the more important story.

Forgotten Genius Fridays
Sarah Boone Improved the Ironing Board by Thinking About the Sleeve
Sarah Boone didn’t invent the first ironing board. The New Haven dressmaker patented a clever improvement shaped for pressing sleeves and fitted clothing.
Forgotten Genius | STM Daily News
Try ironing a sleeve on a wide, flat board. The fabric bunches, the seams curve, and pressing one side can leave a crease on the other. For dressmaker Sarah Boone, that everyday frustration presented a problem she could solve.
Working in New Haven, Connecticut, Boone designed an ironing board shaped for sleeves and fitted garments. Her board was narrow enough for a sleeve to slip over it, allowing one side to be pressed without flattening the other. Its curved edges followed the lines of a sleeve’s seams, while its supports helped position the board for different uses.
Boone filed her patent application in 1891. On April 26, 1892, she received U.S. Patent No. 473,653 for her improvement.
Boone did not invent the first ironing board. What she patented was a thoughtful redesign for a particular task. That distinction makes her achievement more interesting: she understood how the tool was used, recognized where it fell short, and changed its shape to make the work easier.
The patent drawing brings her idea to life. Instead of the broad surface most people picture when they hear “ironing board,” Boone’s design looks almost like the part of a garment it was meant to support. It is a practical solution from someone who knew the job firsthand.
That is the heart of Sarah Boone’s story. Invention does not always begin with an entirely new machine. Sometimes it begins when a person doing familiar work asks a better question: What would this tool look like if it truly fit the task?
Boone answered with a design—and secured a place in the history of Black innovation.

Santa Ana Police Seek Woman Accused of Intentionally Running Over Puppy
Santa Ana police are asking for the public’s help identifying a woman accused of intentionally running over and killing a puppy with a minivan on September 8.
Last Updated on September 30, 2026 by Daily News Staff
SANTA ANA, Calif. — Santa Ana police are asking for the public’s help identifying a woman accused of deliberately running over and killing a puppy after leaving the animal in a residential street earlier this month.
The disturbing incident occurred at approximately 9:15 a.m. on September 8, 2026, in the 900 block of West Park Lane, near 926 W. Park Lane. Police said the dog, described as a pit bull mix puppy, was later found dead in the street.
Investigators subsequently obtained home-surveillance footage showing an older-model green or blue Honda Odyssey minivan stopped along the street.
According to police, the female driver opened the vehicle’s door and placed the puppy on the ground. The puppy went underneath the minivan, and the woman then allegedly placed food on the street near the driver’s side of the vehicle.
As the puppy approached the food, the driver moved the minivan forward. Police said the vehicle’s rear driver’s-side tire went over the puppy and that the minivan remained stopped on the animal for approximately 15 seconds before the driver drove away.
A nearby resident later told officers that they had seen the minivan in the area and believed the puppy had been deliberately run over. Police and animal services personnel spent several weeks canvassing the neighborhood and eventually located surveillance footage that authorities said corroborated the witness’s account.
Police searching for driver
Investigators have not been able to obtain a readable license plate from the surveillance footage.
As of September 30, Santa Ana police were seeking information that could help identify either the woman or the older green or blue Honda Odyssey seen in the video.
Anyone with information about the case is being asked to contact Santa Ana police at 714-245-8378.
The case comes two years after another highly publicized animal-cruelty incident in Santa Ana involving a woman accused of intentionally running over a 2-month-old Rottweiler puppy in August 2024. In that case, the puppy survived after emergency treatment, and the suspect subsequently turned herself in to police.
STM Daily News will update this story if authorities announce an identification, arrest or charges in the case.
