Koassanga

This initiative of the New Aquitaine Region aims to promote the development of agroecology thanks to the transformation of Ecosan latrine sludge into organic fertilisers.

An initiative of Région Nouvelle-Aquitaine / New Aquitaine Region

Overview of the project

Initially, the Koassanga project was a sanitation access project constructing “Ecosan” type latrines. However, the project promoters  did not stop there, deciding to reuse the faecal sludge in the form of organic fertilisers.

After several years of experimentation, the project leaders are, in light of the results, convinced of the usefulness of the latrines and the materials recovered in the form of fertilisers and compost, mainly in terms of:

  • Agricultural yields close to, or even better for certain speculations, than conventional agricultural systems;
  • Savings resulting from farmers’ independence from chemical fertilisers;
  • Improved soil quality and lower watering requirements; and
  • Improved sanitary conditions in the target villages.

As an indicator, Koassanga village is the only one in the Central Plateau Region to have a surplus in terms of agricultural yields, even in recent seasons.

Objective

Promote the development of agroecology.

Level of progress

Ongoing research
