Joyanto Routh

Professor, Head of Unit

My primary interest is in Biogeochemistry and its applications in various environmental issues with definite societal relevance. I teach classes in Environmental Science, Introductory geology and Climate Science.

My research focuses on environmental issues in sedimentary and aquatic systems (e.g. pollution, climate change,food and water security). I teach undergraduate and graduate students, and supervise PhD students.

Ancient seeds give clues on climate change

Thousand-year-old seeds, and traces hidden in the soil for more than 5,000 years, provide clues to how people and their crops were affected by climate change. This knowledge may help us adapt to changes in our lifetime and in the future.

Climate change and the rise and fall of civilisations

Pronounced climate fluctuations and changed conditions for agriculture coincided with the rise and fall of the Persian Empires, according to an international study. The study highlights the vulnerability of human societies to fluctuating climate.

Organisation

Environmental Change (TEMAM)

Almost all nature bears traces of human activity. Its condition is strongly linked to social development. This creates a need for scientific breadth and problem-solving skills. Education and research at Environmental Change respond to this challenge.

Department of Thematic Studies (TEMA)

In an increasingly complicated world, there is a need for researchers that can handle both breadth and depth, and can collaborate across disciplinary borders. Major societal questions are studied from an interdisciplinary perspective at TEMA.
