Etat des lieux sur l’expérience de l’Agriculture de Conservation au Niger

The report assesses conservation agriculture (CA) in Niger, focusing on techniques like Assisted Natural Regeneration (RNA), Zaï, and mulching. It highlights the positive impacts of RNA on crop yields and soil fertility, particularly in the Maradi region, while identifying constraints such as limited crop residue availability and land-use conflicts.

• The use of Faidherbia albida trees improves soil fertility; nitrogen and phosphorus levels under these trees in Niger are estimated to be 200% and 30% higher, respectively, than in open spaces, increasing millet production by 26% for nitrogen and 13% for phosphorus.
• Water harvesting techniques such as Zaï (micro-basins) and half-moons (demi-lunes) have demonstrated a strong capacity to regenerate soil productivity compared to degraded soils where results were often null.
• Mulching has a positive effect on crop yields by maintaining soil moisture and reducing erosion, though its effectiveness is particularly noted when rainfall is below 600 mm.
• Night-penning of livestock on cultivated lands during the dry season (November-April) restores soil fertility; yields obtained through this method varied between 500 and 1521 kg/ha, compared to 418 kg/ha for the control group.
• Major constraints to the adoption of conservation agriculture in rural Niger include the limited availability of crop residues, competition for phytomass, and potential conflicts with nomadic herders over rehabilitated lands.
