Recent research published in ‘VertigO’ has shed light on the significant impact of soil and water conservation (SWC) management practices on the regeneration of woody resources in the Sahelian and northern Sudanian zones of Burkina Faso. Conducted by Souleymane Ganaba, the study underscores the potential for SWC technologies to not only restore degraded lands but also enhance biodiversity and support local agro-pastoral systems.
The study focused on six agro-pastoral units, with particular attention to two located in the northern Sudanian zone—Boundoré and Kabo-Gountouré—and four in the Sahelian zone—Dori North, Falagountou, Korea, and Sampelga. By employing a floristic inventory across 16 pastoral plots, including both managed and control plots, the research evaluated the effectiveness of various SWC techniques. The findings revealed that these management practices significantly favored the reestablishment of both woody and herbaceous vegetation.
One of the standout methods highlighted in the research is the use of half-moons—semi-circular earth embankments designed to capture water and promote soil moisture retention. Ganaba noted, “The half moons management gave the best results on density and floristic composition,” emphasizing the critical role this technique plays in fostering a diverse plant community. The study recorded a notable survival rate of woody plant regeneration, with 9.45% in pastoral plots compared to only 2.65% in cultivated plots since 1999.
Species such as Balanites aegyptiaca, Acacia tortilis, and Acacia senegal emerged as resilient survivors, showcasing their potential as multipurpose trees that can provide fodder and other resources. This resilience is vital not just for ecological restoration but also for the economic viability of local communities that depend on these resources for their livelihoods.
The implications of this research extend beyond environmental restoration; they touch on commercial opportunities within the water, sanitation, and drainage sectors. Effective land management strategies can lead to improved water retention and quality, which are crucial for agriculture and sanitation efforts in arid regions. By investing in these SWC practices, stakeholders can enhance the sustainability of water resources, promote biodiversity, and support the local economy.
As Burkina Faso continues to face challenges related to land degradation and climate change, the findings from Ganaba’s study could serve as a blueprint for future initiatives aimed at sustainable resource management. The integration of SWC technologies not only addresses immediate ecological concerns but also paves the way for long-term economic resilience in the region.
