The research team tackles two main scientific challenges:

  1. Diagnostic and risk assessment of soil and water contamination by pesticides at watershed scale.
  2. Define landscape organization of agricultural management techniques and agro-ecological infrastructures to minimize the spreading of contaminants.

In order to reach this goal, the research team relies on the understanding and modeling of pesticides dynamics.

The main experimental sites are located in Mediterranean and tropical cultivated areas as control of contaminations in these agro-climatic situations has become an increasing challenge.

Démarche Equipe Devenir des Contaminants des Sols et des Eaux



The methodology adopted follows four main ideas:

  • Studying of mobilization and transport properties

This item concerns the study of sorption and transport properties on specific poorly documented substrates (ditches, tropical volcanic soils, saline soils, organic substrates, biocha ...) providing the analytical and experimental facilities of the micro contaminant laboratory of LISAH

  • Study the processes involved in the dispersion dynamics at the local scale (e.g. plot, agro-ecological infrastructures …)

Work is being carried out on the understanding of the processes involved in the dynamics of pesticide dispersion, with a specific focus on poorly documented environments such as the Maghreb or the West Indies. The studies also concern the effect of agronomic practices carried out in viticulture (e.g. grassing of vines, interception of plant cover in rows) or methods of maintenance of agroecological infrastructures (e.g. ditches)

  • Study the processes involved in the dispersion dynamics at the cultivated catchment scale

This item will seek to define a better understanding of the main pesticide transfer pathways at the watershed scale. It includes specific topics of pesticide contribution like: partition between the dissolved and particulate phase or assessment of aerial dispersion to water body contamination. Finally, an approach based on the definition of new cultivated landscape to limit pesticide dispersion is also being undertaken. The latter is based on knowledge acquired at the local scale and on integrated modelling of the fate of pesticides at the landscape scale.

The last two items of are closely related to the observatories OMERE and OPALE

  • Development and evaluation of modelling approaches from the plot to the watershed scale

The objective of this item is to strengthen the develop pesticide fate modelling approaches at both: i) the local scale (e.g. tropical contamination risk assessment, reactive transfer in ditches), and ii) the watershed scale (hydrological modelling of pesticide fluxes). In addition, the development of an integrated modelling approach of the fate of pesticides at the landscape scale (MIPP) will be continued and adapted to the Languedoc wine context.

Works conducted in this item are in closely connection with the OpenFLUID modeling platform.
