From the soil to our plates: understanding the vital role of soil in our food supply

To mark the Fête de la Science, the Roullier Endowment Fund invites you to a public lecture on a subject central to our daily lives: soil and its role in our food supply.

On Monday 12 October, we are delighted to welcome Alain Coléno, former Scientific Director of Crop Production at INRA, a specialist in plant pathology, a bacteriologist and a lecturer and researcher. Still committed to disseminating scientific knowledge, he is currently involved in several charitable initiatives, notably with the AVEC association in Madagascar.

A major challenge for the future

Faced with a constantly growing global population, agriculture must rise to a twofold challenge: producing more to feed people whilst preserving the natural resources essential to food production. Among these resources, soil plays a central role. As the very foundation of life, it provides plants with the water and nutrients necessary for their growth. However, this precious resource, shaped over millions of years, is now under threat from climate change, erosion, water scarcity and certain human practices.

A conference to gain a better understanding of the links between soil and food

During this conference, Alain Coléno will offer an accessible overview of the major agricultural and food issues of today. Participants will learn, in particular:

  • The role of soils in agricultural production and food security;
  • The impacts of climate change on farmland;
  • Issues relating to water management;
  • The various agricultural approaches currently in use;
  • Technical innovations and scientific advances that can sustainably improve food production;
  • Solutions for preserving soil fertility and supporting agricultural transitions.

This meeting will also provide an opportunity to discuss the challenges that the agricultural sector will face in the future in order to balance productivity, environmental protection and food security.
