Enhancing agriculture through farmer managed natural regeneration (FMNR) in Burkina Faso: the case study of the commune of Boussé

Research shows the use of trees by farmers in agroforestry systems improves household nutrition consistent with local culture and food traditions. Additionally, it enhances climate change adaptation while contributing to environmentally friendly agricultural products. Nonetheless, some scientists argue that trees reduce soil moisture content in agricultural settings and that associated water demand could effectively compete with crops over limited available moisture. This research explored these competing claims in the context of Burkina Faso through the lens of farmer managed natural regeneration (FMNR). To assess FMNR’s impacts on soil moisture, a citizen science approach was used to collect soil matric potential data and measure crop yield near and away from trees using the crop-cutting technique. Results demonstrate that FMNR increases soil water availability and crop yield. Trees significantly increased soil moisture throughout the growing season, and crop yields were consistently higher in the canopy zone compared to outside it. These findings highlight FMNR as a sustainable strategy for managing water resources and boosting agricultural productivity. Beyond improving resilience to climate variability, FMNR contributes to addressing food insecurity and water scarcity in Burkina Faso, underscoring its importance as a nature-based solution for sustainable development.
