Comparison between clonal and sexual plantlets ofDetarium microcarpumGuill. & Perr., a savanna tree species in Burkina Faso

In the Sahelian region, different approaches are being used to halt environmental degradation and restore tree cover, with varying degrees of success. Initiatives vary according to projects’ objectives, type of land to restore, and technical practices used (natural regeneration, farmer-managed assisted regeneration, enrichment planting, etc.). This study investigates tree planting choices and selection of tree seed sources in some villages of the Central region of Burkina Faso. The study targeted 96 farmers and compared planting practices adopted by farmers involved in small-scale forest restoration using fences, with those not involved in this initiative. The objective was to understand what portfolio of tree species were planted, what factors influenced tree species selection, what tree seed sources were used, what collection practices were generally adopted, and whether there were significant differences between types of farmers. The results showed that the use of fencing to promote forest restoration support the planting of a more diverse portfolio of tree species than other small scale efforts and includes a greater representation of indigenous trees. Fenced plots have therefore a conservation value in landscapes where the diversity of tree species is progressively declining. In addition to the use of fences, some other key factors affect tree planting, mainly land tenure, availability of diverse tree seed sources, and availability of land. Farmers tend to collect directly most of the planting material they need, but in the majority of cases they do not follow recommended best practices. In light of the ambitious forest restoration targets of Burkina Faso and the need to provide diverse options to rural communities to enhance their resilience vis-à-vis increasing environmental challenges, strengthening the capacity of farmers in tree planting and establishing a robust tree seed systems are crucial targets.

Potential Carbon

AbstractThe success of terrestrial carbon sequestration projects for rural development in sub-Saharan Africa lies in the (i) involvement of local populations in the selection of woody species, which represent the biological assets they use to meet their daily needs, and (ii) information about the potential of these species to store carbon. Although the latter is a key prerequisite, there is very little information available. To help fill this gap, the present study was undertaken in four pilot villages (Kou, Dao, Vrassan and Cassou) in Ziro Province, south-central Burkina Faso. The objective was to determine carbon storage potential for top-priority woody species preferred by local smallholders. We used (i) participatory rural appraisal consisting of group discussions and key informant interviews to identify priority species and functions, and (ii) landscape assessment of carbon stocks in the preferred woody species. Results revealed over 79 priority tree and shrub species grouped into six functions, of which medicine, food and income emerge as the most important ones for the communities. For these functions, smallholders overwhelmingly listed Vitellaria paradoxa, Parkia biglobosa, Afzelia africana, Adansonia digitata, Detarium microcarpum, and Lannea microcarpa among the most important tree species. Among the preferred woody species in Cassou and Kou, the highest quantity of carbon was stored by V. paradoxa (1,460.6 ±271.0 kg C ha−1 to 2,798.1±521.0 kg C ha−1) and the lowest by Grewia bicolor (1.6±1.3 kg C ha−1). The potential carbon stored by the preferred tree communities was estimated at 5,766.2 Mg C ha−1 (95% CI: 5,258.2; 6,274.2 Mg C ha−1) in Kou and 6,664.0 Mg C ha−1 (95% CI: 5,810.2; 7,517.8 Mg C ha−1) in Cassou. The findings of this study will help design data-based development of biocarbon projects, which are rare in the West African Sahel despite being considered as one of the most impactful climate change resilient strategies.

Pentadesma Butyracea

Abstract This paper aims to assess the population structure of Pentadesma butyracea Sabine, a local oil tree species and to analyze the occurrence of woody plants in P. butyracea natural stands. Data were collected in 41 plots of 50 × 20 m across natural stands of P. butyracea in two regions of the south-Sudanian phytogeographic zone of Burkina Faso. Stem diameter, total height and tree health were recorded and the woody plant diversity was assessed. Stand data were calculated and the diameter structure was analyzed at the regional level using the Weibull distribution. Significant differences (P < 0.05) were found in density and basal area between regions. In both regions, 32 per cent of trees show signs of poor health. The diameter distributions of individuals showed a structure close to a reverse J-shape (c < 1). Natural stands of P. butyracea exhibit good natural regeneration, but the large trees in the sampled populations commonly had poor health. The data may indicate early signs of stands of P. butyracea changing into savanna in the Banfora region as a consequence of human activities and climate deterioration. P. butyracea is a dominant species in riparian forest, its conservation has a potential to restore the riparian forest; appropriate management guidance and support that involves local communities is required to ensure sustainable management.
