When he was six years old, his parents sent him to live with his grandparents in Punjab for a year, hoping he would understand his Indian roots. That experience profoundly marked him. It was nothing like his native Essex, in the United Kingdom, which was much grayer and more industrial, and it instilled in Yadvinder Malhi (High Wycombe, UK, 1968) an admiration, curiosity, and passion for nature. Today, this professor of ecosystem science at the University of Oxford is one of the world's most recognized scientific voices in the integration of ecosystem ecology into Earth sciences. His work on climate change and biodiversity loss, especially in tropical forests, has been fundamental. For this reason, he was awarded the 21st Ramon Margalef Prize for Ecology 2025, granted by the Government of Catalonia.
