INRAE presentation

INRAE, the French National Research Institute for Agriculture, Food, and Environment, is a public research organization bringing together 12,000 employees across 272 units in 18 centers across France. As the world’s leading institute specializing in agriculture, food, and the environment, INRAE plays a key role in supporting the necessary transitions to address global challenges.

Faced with population growth, food security challenges, climate change, resource depletion, and biodiversity loss, INRAE is committed to developing scientific solutions and supporting the evolution of agricultural, food, and environmental practices.

Work environment, missions and activities

Nature and purpose of the research project to be developed and related activities
The prospect of the agroecological transformation of agricultural systems is associated with controversies and agronomical challenges to be solved due to the often lower productivity of the agroecological systems, their greater land requirements, their effects on international trade, their interactions with climate change, and their adaptation to changing diets (decrease in share of animal products, increase in legumes). The objective of the recruitment is to develop an integrated mechanistic modelling approach on a vast spatial scale (national, continental and global) to represent the impacts of agroecological management scenarios on plant and animal production, land and biomass use, and biogeochemical and water cycles, in the context of a changing climate. This raises research questions concerning (i) the process representation formalisms, (ii) the formalisation of large spatial scale transition scenarios, and (iii) the characteristics of agricultural systems to be considered to assess their multi-performance.

You will be able to draw on the mechanistic models developed by the ISPA for the simulation of biogeochemical cycles associated with crops and livestock farming, crop yields in response to nutrients, and changes in land use. You could integrate other issues such as water availability and the effect of climate change, especially by coupling with other existing models (e.g. continental surface models). These models will be used for the large-scale assessment of the impacts of the massification of agroecology (reduction in use of synthetic fertilizers, development of organic farming, agroforestry, carbon compensation strategies) on the multi-performance of agriculture (food sovereignty, in situ and remote impacts). The choices regarding the species to be represented (including their conditions of association and succession), the types of crop-livestock associations to be simulated, as well as the levels of input use to be modelled will be built in coherence with the work conducted in the field of systems agronomy and for the large-scale assessment of the most promising agronomical solutions. The objective could be to analyse the synergies and antagonisms between the determining factors of the performances of agroecological systems, and to identify and test alternative solutions (types of agricultural systems and their spatialisation) to bring food systems back within the planetary limits.

Nature and purpose of the teaching project
The teaching project will focus on global agronomy, the agroecological transition, and the assessment of agricultural systems at Bordeaux Sciences Agro (BSA) and the University of Bordeaux. You will develop a teaching module dedicated to global agronomy at the BSA and will teach in the Master’s co-accredited with the University of Bordeaux “Bordeaux Biology Agrosciences” and “Biodiversity, Ecology, Evolution” on the global challenges of food systems. You will coordinate lessons on the assessment of agricultural scenarios for the Master’s 2 course “agroecology and resource management” co-accredited between the University of Bordeaux and BSA. You will develop a course on the challenges and principles of global agronomy and the large-scale assessment of agricultural systems with the new branch “agricultural and forestry science” at the University Doctoral School “Science and Environments”.

Type of contract

Tenure-Track Junior Professor Chair enables recruitment of scientists based on a research and teaching project that lasts three years. At the end of this period, and following an assessment of your scientific achievements and professional capabilities, you may obtain a full-tenure position as Research Director (DR2).

A research and teaching agreement will specify the path you will follow towards full-tenure and enable you to acquire the qualifications necessary to become a full-tenure Research Director in your field.

You have until April 12, 2024 to submit your application. Only candidates previously selected on file by the selection committee will be invited to the hearing.
