AfriqueOuest Ecosols

Eco&Sols is represented in West Africa through the Joint International Laboratory “Ecological Intensification of Cultivated Soils in West AFrica” and LMI IESOL which brings together teams from IRD, CIRAD, ISRA, UCAD, De Thiès University, INERA and University of Ouagadougou Dakar (Senegal) and Ouagadougou (Burkina Faso).

LMI IESOL is a scientific, technical and educational platform for the application of soil sciences to increase agricultural production and preserve the environment. Its aim is to contribute to the development of ecological engineering for the sustainable management of cultivated soil and agrosystems and the intensification of their productivity.

The research themes of Eco&Sols are studied in West Africa in

  • agroforestry systems where dry zone cereals are cultivated
  • rain systems for annual crops which are predominantly cereals grown in association with legumes and
  • peri-urban systems where residual organic products are used as fertiliser for market garden crops.

In Dakar, Eco&Sols has a research facility on the IRD/ISRA Bel Air campus (Laboratory of Soil Microbial Ecology and Tropical Agrosystems, LEMSAT), which is certified to ISO 9001 and has 3 specialist laboratories for characterising the biological state of soils and assessing the effect of soil management methods on microbial biodiversity:

Eco&Sols also uses the services of the IRD LAMA (LAboratoire des Moyens Analytiques) analysis laboratory in Dakar (US191), which undertakes standard physical and chemical analyses of soils, water and plants.
