Efficient water usage in agriculture is crucial for sustaining a growing human population. A better understanding of the systems that support agriculture, farmers and farmlands allows for food production to become more efficient and prosperous.


That's what makes the Monthly Irrigated and Rainfed Cropped Areas Open Source (MIRCA-OS) dataset so important. MIRCA-OS offers high-resolution data on 23 crop classes — including maize, rice and wheat — and helps researchers, students and farmers examine irrigation, rainfall and croplands and how they interact with global water systems.


Co-authored by Endalkachew (Endi) Kebede, a doctoral student in University of Delaware’s Department of Geography and Spatial Sciences, a recent paper focused on MIRCA-OS was published in Nature Scientific Data.


Kyle Davis, assistant professor in the Department of Geography and Spatial Sciences and the Department of Plant and Soil Sciences, served as a co-author on the paper and coordinated the study.


“We first developed a comprehensive data library of crop-specific irrigated and rainfed harvested areas for all countries,” Kebede said. “This involved two years of gathering data from a wide range of international, national and regional sources. Through this process, we produced a tabulated crop calendar, annual harvested area grids and monthly harvested area grids for all irrigated and rainfed crops.”


“The amount of effort that Endi put in to gather, process and harmonize all of this data is truly incredible,” Davis said. “His effort is a very important contribution to the scientific and development communities.”

Cropland accounts for 13% of Earth's total habitable land, and the preservation of cropland is important in feeding the growing global population.


“Crop production has been a widespread human activity for a few thousand years, and it has a huge role in global food security,” Kebede said. “But it also has unintended impacts on the environment, such as overutilization of water resources, pollution through rivers or the effects on soil and the environment.”


MIRCA-OS can play a crucial role in helping to better understand croplands and agriculture, allowing the global population to be successfully fed while minimizing the agricultural effects on the environment.


In addition to the data included on cropland and water resources, MIRCA-OS allows researchers to view social aspects like poverty and unemployment through an agricultural lens, creating a better understanding of the interconnectivity of agriculture and social issues.


MIRCA-OS is an updated version of the earlier MIRCA2000 dataset. Kebede said the MIRCA2000 was released nearly two decades ago, so renewing the data gives users more accurate and timely information.


Both datasets specialized in examining irrigation and rainfall, but the MIRCA-OS added two new complexities to their data.


First, MIRCA-OS is open source, meaning it is publicly available for anyone to use, download, or modify. Kebede said the added accessibility allows the technology to contribute to anyone's work, whether it be a student, a researcher or a farmer.


“Anybody can use, update it, or upscale it to the special skill they’re interested in,” Kebede said. “Some might use it for research, some might use it to create policies and some might use it to practice agriculture.”

Two years after the 2024 election, where does civil discourse stand? featured image

Two years after the 2024 election, where does civil discourse stand?

Election season has brought the expected vicious political campaign ads, heated online disagreements and difficult dinner table conversations with family and friends. But the University of Delaware’s Timothy Shaffer says there’s still room for civil discourse. Shaffer, UD’s inaugural Stavros Niarchos Foundation (SNF) Chair of Civil Discourse, studies how people can engage across significant differences while maintaining the relationships and democratic institutions that make disagreement possible. As chair of UD's SNF Ithaca Initiative, Shaffer works with students, educators and civic leaders to develop and practice constructive engagement across differences. He can comment on the following through the lens of the first midterm election since the vitriolic 2024 general elections. • What has changed since 2024: How have the past two years affected the way Americans talk about politics, disagreement and democracy? • Polarization and dialogue: Is political disagreement itself the problem, or is the greater challenge engaging constructively across differences? • The role of disagreement: Why civil discourse doesn't require consensus and how listening to competing perspectives can strengthen democratic engagement. • Politics and personal relationships: How to navigate political differences with family, friends, neighbors and colleagues without letting disagreements become personal. • Social media and the 2026 election: How online environments shape political conversations, what Shaffer expects as Election Day approaches, and how people can engage more constructively across differences.

Blood Clots Can Sideline Elite Athletes. Could Microrobots Offer a New Approach?

Blood clots have sidelined or ended the careers of several elite athletes, drawing attention to a potentially life-threatening condition. The University of Delaware's Sambeeta Das is part of a team that has developed tiny, magnetically guided robots that could offer a new approach to removing such blockages. The list of athletes affected by blood clots includes NBA champion Chris Bosh, whose career ended after recurring clots; tennis great Serena Williams, who survived two life-threatening pulmonary embolisms; San Antonio Spurs center Victor Wembanyama, who was shut down in February 2025 when deep vein thrombosis was discovered in his right shoulder; and Philadelphia Eagles quarterback Jalen Hurts, whose recent diagnosis of blood clots in his lungs has drawn national attention. In a published study, Das and her colleagues demonstrated that magnetic microrobots could mechanically break apart clusters of human liver cancer cells and clear them from narrow channels designed to model blood vessels. The robots used mechanical forces rather than drugs or chemicals to disperse the clusters. The research offers an early proof of concept for using microrobots to remove unwanted cellular material in confined spaces. Das can discuss how the technology works, its potential application to blood-clot removal, the challenges of targeting blockages inside the body, and what further research is needed to explore its use in patients.

From Baseball to Business: The Science of Team Success

The ingredients that create a World Series team often mirrors how units achieve success in business. How did they get there? The University of Delaware's Kyle Emich says the answer goes beyond assembling a roster of star players. Emich, a professor of management, says that how players combine their strengths, respond to opponents and create opportunities together can be just as important as individual talent. The same is true in business, where a collection of talented employees doesn’t automatically translate into a high-performing team, he said. One example is the approach that the 2026 Milwaukee Brewers’ took during their postseason run. Rather than relying exclusively on home runs and individual star power, the team created opportunities through a combination of speed, patience at the plate, timely hitting and pressure on opposing defenses. A stolen base, a walk or a defensive mistake might seem like a small event on its own, but the effects can build as players’ actions interact. These interactions matter, he says, because teams are not simply collections of individuals; their performance emerges from how people and their activities affect one another within a larger environment. The same is true in business as well as baseball. Businesses may recruit exceptional employees or invest in promising technologies such as artificial intelligence, yet fail to realize their potential if their processes, team structures and working practices don’t support those strengths. Emich can discuss: • Beyond Moneyball: What baseball’s emphasis on statistics and individual talent reveals about the limits of evaluating people in isolation. • Building better teams: How coordination, complementary strengths and the interaction among team members contribute to performance. • Strategy and competition: What baseball teams’ adjustments to opponents can teach business leaders about responding to competitors and changing conditions. • Technology and the future of work: Why adopting artificial intelligence or other new technologies is not enough without considering how people, processes and technology work together.
