Science begun in the sertão possesses excellence for global solutions
From the arid interior of Pernambuco, a young researcher named Hermógenes Bezerra Maia has carried the soil of his homeland to the highest stage of international soil chemistry, receiving the Malcolm Award — the most distinguished honor of the International Humic Substances Society. Granted to only a handful of doctoral students worldwide at each biennial conference, the prize recognizes his work on organic fertilizers and sustainable inputs for semiarid agriculture. It is a reminder that scientific excellence does not belong to any single geography, and that the questions born from living close to the land can become answers the whole world needs.
- A 29-year-old doctoral student from a small city in Brazil's interior has won one of the most competitive scientific honors in global soil chemistry, awarded to as few as six researchers worldwide per cycle.
- The recognition arrives in a field where access is unequal — Serra Talhada had no graduate chemistry programs, forcing Maia to build his career across institutions and states.
- His research targets a pressing global tension: how to sustain agriculture in arid and semiarid regions without deepening environmental degradation.
- Mentors across two universities bridged the institutional gap, connecting his undergraduate vermicomposting work in Pernambuco to a doctoral program in Sergipe and ultimately to an international audience.
- In August 2026, Maia will present his findings in Brno at the 29th IHSS conference, where his work on humic substances may begin shaping sustainable agriculture policy at a global scale.
Hermógenes Bezerra Maia, vinte e nove anos, nascido em Serra Talhada no sertão pernambucano, acaba de receber o Prêmio Malcolm — a maior honraria da International Humic Substances Society, uma das mais influentes organizações científicas mundiais na área de química do solo. Doutorando na Universidade Federal de Sergipe, ele pesquisa insumos orgânicos e fertilizantes capazes de tornar a agricultura mais sustentável, especialmente em regiões áridas e semiáridas.
O prêmio é concedido a apenas um estudante de destaque entre os bolsistas de pós-graduação presentes em cada conferência bienal da IHSS — um universo que historicamente não ultrapassa vinte contemplados no mundo inteiro. O caminho de Maia até essa distinção começou na própria Serra Talhada, onde seus pais, Zeneide e Demógenes, fizeram da educação uma prioridade. Na UFRPE/UAST, sob orientação do professor Ramom Rachide, ele se dedicou à vermicompostagem e ao uso da água da piscicultura no solo semiárido — pesquisa que plantou nele a vocação pela ciência ambiental.
Quando chegou a hora de avançar para a pós-graduação, Serra Talhada não oferecia programas de mestrado ou doutorado em química. Foi Rachide quem o conectou à professora Luciane Pimenta, na UFS, que se tornou sua orientadora doutoral. A parceria permitiu que Maia aprofundasse sua trajetória em química analítica ambiental sem perder as raízes do que havia começado no sertão.
Ao falar com a imprensa, Maia descreveu o prêmio como transformador, comparando seu peso ao de um Nobel em sua área específica. Em agosto de 2026, ele apresentará seus resultados na 29ª conferência da IHSS, em Brno, na República Tcheca. O que nasceu como projeto de iniciação científica numa cidade sem pós-graduação tornou-se pesquisa reconhecida internacionalmente como capaz de propor soluções sustentáveis em escala global.
Hermógenes Bezerra Maia is twenty-nine years old, from Serra Talhada in the interior of Pernambuco, and he has just won the Malcolm Award—the highest honor given by the International Humic Substances Society, one of the world's most influential scientific bodies in his field. He is a doctoral student in chemistry at the Federal University of Sergipe, where he studies how to create organic inputs and fertilizers that make agriculture more sustainable, particularly in arid and semiarid regions.
The award itself is rare. The IHSS holds international conferences every two years in different countries, and at each gathering, it grants travel support to help graduate students attend. Among those recipients, only one stands out as exceptional enough to receive the Malcolm Award—named for Dr. Ronald Malcolm, the society's founding president. Historical records suggest that between six and twenty students from across the entire world are honored this way at each conference. The competition is fierce.
Maia's path to this recognition began in Serra Talhada, where his parents—Zeneide, a retired teacher, and Demógenes—prioritized education for him and his brother, Elyemerson. He studied chemistry education at the Federal Rural University of Pernambuco's Serra Talhada campus, where he worked on vermicomposting and fish farming water applications under the guidance of Professor Ramom Rachide. That early research focused on improving soil quality in the semiarid landscape where he grew up. It was there, in those initial experiments, that he found his calling in soil science and environmental chemistry.
When it came time to pursue graduate work, Serra Talhada had no master's or doctoral programs in chemistry. Rachide connected him with Professor Luciane Pimenta at the Federal University of Sergipe, who became his doctoral advisor while Rachide continued as co-advisor. The arrangement allowed Maia to deepen his work in environmental analytical chemistry, building on the foundation he had laid years earlier in his hometown.
When Maia spoke with reporters this week, he described the award as transformative. He credited his parents' investment in his education and his mentors' guidance in shaping a research trajectory that began in the Pernambuco interior but now reaches the global stage. He will present his findings at the twenty-ninth IHSS conference in Brno in August 2026. In his own words, he said the recognition carries weight comparable to winning the Nobel Prize in his specific area—the study of humic substances and natural organic matter. What started as an undergraduate project on vermicomposting in a region without advanced degree programs has become work that the international scientific community recognizes as excellent and capable of proposing sustainable solutions at a global scale.

La Conversación del Hearth Otra perspectiva de la historia
Why does an award for soil chemistry matter to people who aren't scientists?
Because soil is where food grows. If you can make fertilizers that work better and harm the environment less, especially in dry regions where farming is already difficult, that changes what's possible for farmers and for the land itself.
How did someone from a small city in the interior end up competing at this level?
His teachers saw something in him and opened doors. Rachide didn't just teach him—he connected him to the right advisor at the right university. That kind of mentorship across institutions is what allows talent to develop even when your hometown doesn't have all the resources.
What makes this award so competitive?
Only six to twenty students win it globally every two years. That's from thousands of doctoral candidates worldwide. The IHSS is one of the most respected organizations in soil and organic matter research, so being selected means your work has been judged against the best.
Does winning change what he does next?
It gives him a platform. He'll present at a major international conference in August. That visibility opens collaborations, funding opportunities, and credibility that a young researcher from the interior of Brazil might not otherwise have access to.
What was he studying, exactly?
How to make better organic fertilizers and soil amendments, particularly using techniques like vermicomposting and agricultural byproducts. The goal is sustainable farming in semiarid regions—places where water and resources are scarce and you can't afford to waste anything.
