Joint Research Unit EcoSys

INRAE - AgroParisTech

 

EcoSys is a Joint Research Unit located on the AgroParisTech-INRAE campus in Palaiseau. Our research focuses on understanding the functioning of agro-ecosystems in relation to agricultural practices, their response to global change and interactions with urban and peri-urban environments. Our work is rooted in and organized around our core strength, namely the articulation of biophysical-based approaches to experimentation, observation and modeling at different temporal and spatial scales. Our research focuses on the multifunctionality and health of soils, particularly in urban and peri-urban contexts, the regulation of surface-atmosphere exchanges and emissions of contaminants into the air, terrestrial ecotoxicology from plot to landscape (landscape structure considered as a factor in the regulation of ecological and biogeochemical flows) and the sustainable management of biogeochemical cycles on territorial and regional scales.

Our collective project aims to support the agro-ecological and energy transition by assessing the different levers of agro-ecology for mitigating and adapting to climate change, strengthening the integration of agricultural systems into the bio-economy of territories, and contributing to a global approach to health. The main levers explored are

- Organic soil management: recycling of organic waste products, simplified tillage, management of crop residues and intercropping, agroforestry,

- Nitrogen fertilization: low input levels, organic fertilization,

- Cultivated and associated biodiversity: introduction of legumes in cultivated mixtures, species diversity in crop successions, soil biodiversity and associated functions,

- Crop protection strategies: reduction of phytosanitary products, biopesticides and substitute molecules authorized for biocontrol, biological regulation of pests via auxiliaries and companion plants,

- Soil use and landscape structuring: distribution of crops and other landscape elements (meadows, hedges, ecological infrastructures) as a function of spatial soil variability.
