DES MOINES, Iowa: A Brazilian scientist who pushed back against chemical fertilizers and researched biologically based approaches to more robust food production has been honored with this year’s World Food Prize, the organization announced Tuesday.
Microbiologist Mariangela Hungria’s research helped her country become an agricultural powerhouse, an accomplishment that has now won her $500,000 from the Iowa-based World Food Prize Foundation. Hungria has been researching biological seed and soil treatments for 40 years, and has worked with Brazilian farmers to implement her findings.
“I still cannot believe it. Everybody said, my whole life, it’s improbable, you are going the wrong way, just go to things like chemicals and so on. And then, I received the most important prize in the world of agriculture,” Hungria said in an interview. “Sometimes I still think I’ll wake up and see that it’s not true.”
Norman Borlaug, who received the Nobel Peace Prize in 1970 for his work to dramatically increase crop yields and reduce the threat of starvation in many countries, founded the World Food Prize. Since the first prize was handed out in 1987, 55 people have been honored.
Hungria said she grew up wanting to alleviate hunger. Early in her career, she decided to focus on a process called biological nitrogen fixation, in which soil bacteria could be used to promote plant growth. At that time, farmers in Brazil and around the world were reluctant to reduce their use of nitrogen fertilizers, which dramatically increase crop production but lead to greenhouse gas emissions and pollutes waterways.
Hungria studied how bacteria can interact with plant roots to naturally produce nitrogen. She then demonstrated her work on test plots and began working directly with farmers to convince them that they wouldn’t have to sacrifice high crop yields if they switched to a biological process.
The work is credited for increasing yields of several crops, including wheat, corn and beans, but it has been especially affective on soybeans. Brazil has since become the world’s largest soybean producer, surpassing the United States and Argentina.
Although Hungria’s research could be applied on farms in other countries, soybean production in the US is different than it is in Brazil; American farmers typically rotate crops on their land between growing corn and soybeans. Enough nitrate fertilizer applied to corn still remains in the soil when soybeans are planted that little or no fertilizer needs to be applied, Hungria said.
Brazilian agricultural companies have faced fierce criticism for clearing forested land to create farmland, largely to grow soybeans.
Much of that criticism is justified, Hungria said, but she added that her biological approach builds up the soil and makes further encroachment into forested areas less necessary.
“If you manage the crop well, the crop will enrich the soil with nitrogen. Soil health improves if you do the right things,” she said.
Hungria will be awarded her prize at an annual October gathering in Des Moines of agricultural researchers and officials from around the world.
Gebisa Ejeta, chair of the World Food Prize Laureate Selection Committee, credited Hungria for her “extraordinary scientific achievements” that have transformed agriculture in South America.
“Her brilliant scientific work and her committed vision for advancing sustainable crop production to feed humanity with judicious use of chemical fertilizer inputs and biological amendments has gained her global recognition both at home and abroad,” Ejeta said in a statement.

PARIS: The last time Kim Kardashian faced the men that police say robbed her, she was bound with zip ties and held at gunpoint, and feared she might die. On Tuesday, nearly a decade later, she returns to Paris to testify against them.
One of the most recognizable figures on the planet is expected to take the stand against the 10 men accused of orchestrating the 2016 robbery that left her locked in a marble bathroom while masked assailants made off with more than $6 million in jewels.
Kardashian is set to speak about the trauma that reshaped her life and redefined the risks of celebrity in the age of social media. Her appearance is expected to be the most emotionally charged moment of a trial that began last month.
Court officials are bracing for a crowd, and security will be tight. A second courtroom has been opened for journalists following via video feed.
Kardashian’s testimony is expected to revisit, in painful detail, how intruders zip-tied her hands, demanded her ring, and left her believing she might never see her children again.
Twelve suspects were originally charged. One has died. Another has been excused from proceedings due to serious illness. Most are in their 60s and 70s — dubbed les papys braqueurs, or “the grandpa robbers,” by the French press — but investigators insist they were no harmless retirees. Authorities have described them as a seasoned and coordinated criminal group.
Two of the defendants have admitted being at the scene. The others deny any involvement — some even claim they didn’t know who Kardashian was. But police say the group tracked her movements through her own social media posts, which flaunted her jewelry, pinpointed her location, and exposed her vulnerability.
The heist transformed Kardashian into a cautionary tale of hyper-visibility in the digital age.
In the aftermath, she withdrew from public life. She developed severe anxiety and later described symptoms of agoraphobia. “I hated to go out,” she said in a 2021 interview. “I didn’t want anybody to know where I was … I just had such anxiety.”
Her lawyers confirmed she would appear in court. “She has tremendous appreciation and admiration for the French judicial system,” they wrote, adding that she hopes the trial proceeds “in an orderly fashion … and with respect for all parties.”
Once dismissed in parts of the French press as a reality TV spectacle — and lambasted by Karl Lagerfeld for being too flashy — Kardashian now returns as a key witness in a case that has forced a wider reckoning with how celebrity, crime, and perception collide.
Her lawyers say she is “particularly grateful” to French authorities — and ready to confront those who attacked her with dignity.
