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

This report evaluates the state of Conservation Agriculture (CA) in Niger, identifying potential technologies, their impacts on soil fertility and crop yields, and the socio-economic constraints hindering their widespread adoption in rural areas.

• Assisted Natural Regeneration (RNA) has significantly improved agricultural productivity and living conditions in the Maradi region. In Aguié, millet grain yields increased by 32 to 165 kg/ha for RNA under 3 years, 59 to 221.5 kg/ha for RNA between 3 and 6 years, and 120 to 209.5 kg/ha for RNA over 6 years.
• Water harvesting techniques such as 'tassas' (circular micro-basins) and 'demi-lunes' (half-moon basins) have proven effective in regenerating soil productivity on degraded and crusted lands, yielding results that were double the departmental average in some cases.
• Mulching has a positive impact on crop yields by maintaining soil moisture and reducing erosion. In the Tillabéry region, intensive mulching using 2,000 kg of crop residues reduced erosion to 7.4t/ha or 10.8t/ha, compared to 20.3t/ha in control plots.
• The practice of penning livestock on cultivated lands during the dry season (November to April) restores soil fertility. Yields from this method varied between 500 and 1,521 kg/ha, compared to 418 kg/ha for control plots.
• Precision Conservation Agriculture, specifically 'micro-dosing' of fertilizers, has been implemented across 832 villages in 7 regions through the Alliance for a Green Revolution in Africa project.
• The adoption of Conservation Agriculture in rural Niger is hindered by several constraints, including irregular rainfall, low intrinsic soil fertility, competition for phytomass, and limited availability of crop residues.
