Abstract

The soil is our shared heritage, which must be protected and preserved given the vital functions it performs. While its role in food production is well known, its dynamics and the biodiversity it supports play a key role in regulating the water cycle and greenhouse gas cycles, as well as in the production of essential minerals. The soil ecosystem is both a biological and chemical reactor—organized, structured, and living—on which we depend. However, its resilience has limits. Human pressures, such as pollution, can lead to an irreversible imbalance in its functional capacities.

What can we do? Today, there’s a lot of talk about nature-based solutions. What are they? Are there any concrete examples of success?

This lecture will be followed by a seminar presented by Dr. Martine Hossaert-McKey, Research Director at the CNRS, Scientific Advisor for Biodiversity and Overseas Territories, and Co-Director of the PEPR SOLU-BIOD. Her seminar will focus on nature-based solutions(NBS) and soils: an essential partnership.
