Program

The BIOGEOMON Conference, with its inclusive approach to the biogeochemistry of terrestrial and aquatic environments, has been held every 2nd or 3rd year since 1987. Twenty interdisciplinary sessions are planned for BIOGEOMON 2026.

Preliminary Program, Session Themes & Invited Speakers – BIOGEOMON 2026

BIOGEOMON 2026 brings together leading researchers from across the globe to explore the biogeochemical processes that underpin ecosystem function and resilience in a changing world. This year’s sessions span a wide array of themes—from critical zone science and aquatic-terrestrial linkages to climate extremes, land-use change, and ecosystem restoration. Each session is led by invited experts who will share the latest insights and foster discussion across disciplinary boundaries.

Below is an overview of the program, session topics and our distinguished invited speakers.

BioGeoMon 2026 is proud to welcome a distinguished group of plenary speakers who are internationally recognized for their contributions to biogeochemistry, ecosystem science, and environmental change. These leaders will open each day of the conference with inspiring talks that reflect the breadth and urgency of our field—from critical zone processes and climate extremes to interdisciplinary frontiers.

Our plenary sessions are designed to set the stage for in-depth discussions, highlight emerging research, and foster connections across disciplines. Join us in Umeå to hear their perspectives and help shape the future of biogeochemical research.

A full list of plenary speakers will be announced soon.
