“…Previous studies of gum production have involved stands of S. senegal trees with a diameter ≥ 4 cm [17]. In this study, we sampled trees with a diameter ≥ 2 cm because Yebeyen [43] reported that these trees are considered to be sufficiently mature for gum production purposes.…”

“…The species is highly valued for its production of gum arabic from trunks, branches and twigs [16]. Gum arabic has a wide range of technological applications in the food, pharmaceutical, and cosmetic industries [16,17] and, hence, is considered a very important economic resource worldwide [18]. Senegalia senegal is also ecologically important because it improves soil fertility and is widely used to control desertification [19].…”

“…Furthermore, S. senegal trees also provide wood for use as fuel and local construction materials, as well as leaves and pods, which are used as livestock fodder. In addition, the nitrogen-fixing ability of S. senegal trees makes them highly suitable for use in agroforestry systems, where they are grown in combination with agricultural crops [17].…”

“…Deforestation in this area is driven by rapid population growth and the consequent clearance of forests for cropland expansion and by overgrazing [21], which seriously affects the population and regeneration of valuable tree species such as S. senegal [22]. Although some studies have investigated the growth performance, gum yield [17], and socioeconomics [4,11] of this species, S. senegal populations in different parts of Ethiopia are still inadequately characterized. Managing dry forests so that they can produce a range of NTFPs, such as gum and resin, even to a certain extent in combination with forest-compatible uses such as livestock grazing [11], is considered critical for their continued viability as a source of crucial resources in dryland areas of Ethiopia.…”

Senegalia senegal (L.) Britton is a multi-purpose dryland tree species that produces gum arabic, a commercially valuable product. However, this resource is underused in Ethiopian dryland areas. The aim of this study was to evaluate the population status and potential gum yield of S. senegal growing in natural stands in South Omo Zone, Ethiopia. Forty-five sample plots, each measuring 20 × 20 m, were established at 500 m intervals along transects, with 1 m2 subplots located within the main plots to determine regeneration. S. senegal trees with a diameter at breast height of between 2 and 12 cm were most prevalent. Forty-two tree species were associated with S. senegal, of which 16 were gum- and resin-producing species. S. senegal was positively associated with Vachellia tortilis, Senegalia mellifera, Vachellia nilotica, Commiphora edulis, and Dobera glabra. Senegalia senegal comprised approximately 35% of regenerating trees. The maximum gum arabic yield obtained was 3948 g tree−1. Linear models of dendrometric variables indicated that gum arabic yield is better predicted by tree diameter than by height. Despite the limitations of this pioneer survey, the population status and yield potential suggest that gum arabic could be sustainably produced and commercialized in natural stands of S. senegal in the studied dryland areas, providing local communities with supplementary seasonal incomes.

Climate significantly impacts dryland trees, influencing their adaptation, survival, production, and role in the ecosystem. Acacia senegal is a valuable dryland tree planted for gum arabic production and ecological benefits. However, gum arabic production has declined due to the adverse effects of climate and improper management. Thus, silvicultural intervention such as pruning is essential for the health, growth, and gum yield of A. senegal. This study investigates the effects of different pruning intensities and pickings on gum arabic yield at Madana and Garin-ladan in the Gumel district of northern Jigawa State, Nigeria. The experiment involved five levels of pruning intensity and eight pickings, conducted using a randomized complete block design with three replicates. The gum yield was collected, dried, and weighed, and ANOVA was performed using Statistix 10.0 software, with Shapiro-Wilk and Turkey tests for data normality and mean comparison. The result showed significant differences (p < 0.05) in gum yield among the pruning intensities for most of the pickings at the two sites. The 1st, 2nd, 3rd, 5th, 6th, and 3rd, 5th, 8th pickings are significantly different except 4th, 7th, 8th; and 1st, 2nd, 3rd, 6th, and 7th at Madana and Garin-ladan respectively. The highest gum yield is 52.5a, 46.7a, 50.1a, and 43.5a g/picking, respectively. The lowest is 0.8a and 0.9a g/picking, respectively. Pruning intensity significantly differs (p< 0.05) in total gum yield per tree. Pruning intensities B3 and B4 demonstrated the highest total gum yield (251.8a and 147.6a g/tree) at both sites, respectively. At the same time, B0 exhibited the lowest gum arabic yield (97.2c and 38.5b g/tree) at both locations. These findings prove that pruning intensities B3 and B4 are the most effective in promoting gum yield and may enhance the gum productivity of A. senegal trees in northern Jigawa State.
