Researcher in the ecophysiology of banana trees in agroforestry systems M/F

Vacancy details


Future organization (department / unit)

CIRAD, the French Agricultural Research Centre for International Development, works with its partners in southern countries to generate and pass on new knowledge to support agricultural development and innovation.

It has one main objective: to build sustainable farming systems for tropical and Mediterranean regions capable of feeding ten billion human beings by 2050 while preserving the environment.

Job title

Researcher in the ecophysiology of banana trees in agroforestry systems M/F

Begining date


Job description

Over the past 10 years, the Research Unit for ‘Ecological functioning and sustainable management of banana and pineapple agrosystems' (RU GECO) has carried out innovative research to support the agroecological transition of banana agrosystems in the French West indies via the introduction of service plants in the herbaceous stratum. Currently, our ambition is to continue to increase the diversity of banana agrosystems by including a tree stratum in order to produce more diverse ecosystem services. This new dimension in the approach to innovative agroecological systems is an opportunity to mobilise new tools in the regulation of bio-aggressors and to reach wider ecosystem services, whilst also limiting disservices. The study of interspecific interactions, particularly competition for resources within an agrosystem is crucial. As such, understanding how mineral, water and radiative resources are shared in multi-strata systems is a major element in the design of agronomically effective agroforestry systems.
It is within this framework that you will study the overall functioning of banana trees in relatively simple monoculture systems as well as in multi-specific associations. You must quantify the effects of associations of other species on the mechanisms of competition and compensation, particularly in terms of processes related to photosynthesis and the allocation of carbon assimilates within banana trees. Given that the mechanisms of compensation likely vary from one genotype to another, you will identify the most adapted genotypes of banana trees for multi-specific, multi-strata agricultural ecosystems.
The current simulation models for banana functioning do not correctly integrate the limited conditions of resources, compensation mechanisms, nor varietal diversity. You will work in close collaboration with agronomists and modellers in the unit to produce new findings on the ecophysiology of banana trees to better characterise the compensation mechanisms and the remobilisation of assimilates under the effects of various factors: limited resources, cultural practices, and varietal diversity. This work will help update the modelling approaches for how banana trees function in multi-specific stands.
The finalised objective of this research is to optimise the management of banana trees (including management practices of source_sink ratio : sucker selection, deleafing strategies, etc.) and their spatial arrangement within disruptive agroecological cropping systems.
The post is based in Guadeloupe at the Capesterre-Belle-Eau site.

Desired profiled

You must have a doctorate in plant ecophysiology and ideally have experience in modelling plant functions and/or familiarity with multi-specific systems.

Skills required:
- Expert knowledge in plant ecophysiology, agronomy, and functioning of cultivated systems
- Experience in in situ measurements of carbon and water mechanisms

- Knowledge in the operations of multi-specific stands (interspecific interactions) would be a plus
- Experience in eco-physiological modelling would be a plus for working with the unit's modellers
- Strong ability to integrate multiple subject matters
- Able to work as part of a team

You are very interested in working in tropical conditions and are oriented towards experimental, on-the-ground approaches.
