Agroecology and Environment research unit (AGE)

The research unit Agroecology and Environment (AGE) works on the adaptation and development of agroecological practices to ensure economic, social and environmental sustainability of agroecosystems.


Our main goal is to evaluate and design production systems integrating agroecological practices that combine production and natural resources preservation. We want to evaluate:

1. Underlying ecological and biological processes for production

2. Natural resources preservation

3. Agronomic performances

Schéma AGE

These research goals request to understand the changes in ecological and biological processes induced by agroecological practices.

The research team also works on the development and implementation of co-design systems by farmers and researchers that allow integrating scientific and technological innovations in farming systems.



The research team focuses mainly on organic and low input cropping systems. Our activities deal with different topics including autonomy in nitrogen supply and quality of cereal products, management of soil fertility and ecosystem services supported by biodiversity in agroecosystems.

Key words:  organic agriculture, low input system, relay intercropping cereals/legumes, cover crop, reduced tillage, direct seeding, soil quality and fertility, conservation biological control, water quality, system resilience.



Our goal is to co-design agroecological fish pond systems managed for fish production in taking into account the economic constraints of professionals with whom we closely work. The management model relies on the implementation of practices that allow an increased use of biological productivity of ponds, favoring at the same time fish resources development and biodiversity preservation.  

Key words: management of the balance phytoplankton/aquatic plants, corrective fertilization, management of years without water in ponds, liming, management of the balance among fish species, nutrient and pesticide transfer from catchments to ponds.
