Exploring the Role of Traditional Ecological Knowledge in Restoring and Managing Miombo Woodlands: A Case Study from the Lubumbashi Region, Democratic Republic of the Congo

The overexploitation of forest resources in the Lubumbashi Charcoal Production Basin in the southeastern Democratic Republic of the Congo (DR Congo) leads to deforestation and miombo woodlands degradation, threatening local livelihoods. Current forestry policies are ineffective, partly due to neglecting traditional ecological knowledge (TEK). This study identifies and describes TEK and practices related to biodiversity conservation and sustainable miombo woodlands management. Focus groups and interviews were conducted in four villages (Maksem, Mwawa, Nsela, and Texas), selected based on forest resource availability and population size. Data on sacred sites, conservation practices, knowledge transmission, ceremonies, and socio-demographic factors were analyzed using descriptive statistics, Fisher’s exact test, and Jaccard’s similarity index. The findings revealed that 75% of respondents identified sacred sites where logging activities are strictly prohibited. Thirty sacred tree species were identified, with stronger compliance in villages with a high availability of forest resources. This TEK is predominantly transmitted orally through family councils, as well as traditional ceremonies or rituals. Conservation practices include small-scale farming, intercropping, avoiding tree cutting in sacred sites, and using deadwood. However, only farming and intercropping are still commonly practiced, particularly in resource-scarce villages (64%). Women and elders are primary custodians of TEK, though its application is constrained by population growth and dwindling forest resources. The findings emphasize the crucial role of TEK in strengthening forest restoration initiatives by selecting key woody species and sustainable practices, while fostering community involvement. As such, decision makers should prioritize integrating TEK into DR Congo’s forest policies to support biodiversity conservation and miombo woodlands restoration efforts.
