“…In Kwara State, natural regeneration is very potent considering the rapid growth rates and spread of many native tree species, especially Pterocarpus erinaceus and Vitellaria paradoxa [43,44,45].…”

Remote sensing/GIS techniques are a versatile tool for x-raying serial forest structural changes in retrospect. It would be impossible to evaluate past occurrences and changes in forest extents in past decades at Effan Forest Reserve without non-conventional means. Therefore, we adopted remote sensing technology using Landsat images to evaluate land-use change and degradation rates in the area with a view to ascertaining causal factors for possible minimization of forest degradation in Effan Forest Reserve. Land-use/land-cover changes were analyzed using USGS-Landsat TM and ETM images of 1987, 2002, 2014 and 2019. Field-data were collected using handheld GPS receiver and spatial statistical analyses were conducted using the ground control points (GCPs). For inventory data, a systematic sampling technique was adopted using ten 1.05 km-transects at 500 m intervals. A total of 50 sample plots of 50 × 50 m were used. All tree species with Dbh ≥10 cm were enumerated. Nineteen tree species in ten families were encountered with Vitellaria paradoxa as the most-frequently occurring species in the area. IUCN-listed endangered Pterocarpus erinaceus, hitherto abundant in the area, was rarely encountered during the survey, while Vitellaria paradoxa is gradually shrinking, going the relative abundance in the area. The result further showed that primary and secondary forests decreased considerably by 258.03 ha (46.72%) and 9.18 ha (3.63%), respectively, with a total forest loss of 50.3% in 32 years (8.4 hayr-1, 1.6% per annum). While forest plantation size doubled by 369.72 ha within the period. This is worrisome as the remaining fragmented forests appeared to be on the decline, except the riparian vegetation, due to inaccessibility to the riparian by loggers. It thus appeared that forest protection approaches were ineffective. Increased protection efforts could save this forest reserve, and the concerned authority should consider a focused-enrichment planting involving indigenous species for ecosystem-repair.

“…Vitellaria paradoxa (Butryspermum paradoxum) commonly known as shea butter tree is a well-known plant with several applications in herbal medicine (Ajijolakewu and Awarun, 2015) [2] . The plant is very common in the northern than southern parts of Ghana especially they are in abundance in Navrongo in the Upper East region of Ghana (Adelibigbe et al, 2017) [1] . It is a very common tree which occurs largely in off-reserves in some parts of Africa including northern Ghana (Maistrello et al, 2011;Jasaw et al, 2015) [14,12] .…”

In this study, total phenolic contents and antioxidant activities of ripe and unripe fruits from extracts (70% (v/v) acetone, 70% (v/v) ethanol and hot water (70 o C) of Vitellaria paradoxa (Shea fruit) were investigated. The total phenolic contents and antioxidant activities of these extracts were compared. Additionally, the extraction potentials of 70% (v/v) acetone, 70% (v/v) ethanol and hot water (70 o C) were also compared. The extracts were analyzed for their total phenolic contents using the Prussian blue assay and the antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. This study showed that the Shea fruit (Vitellaria paradoxa) is a good source of natural antioxidants and that unripe fruits of Vitellaria paradoxa contain higher phenolic content and antioxidant activity than the ripe fruits.

“…Nigeria accounts for 62 percent of the estimated 600,000 metric tons produced in West Africa (Enaberue et al, 2011). The tree however, is endangered due to the good qualities of the trunk as a slow burning fuel wood (Aderibigbe et al, 2017). It has therefore attracted protection against extinction from concerned agencies in some African countries (Buyinza and Okullo, 2015).…”

This study assessed the value chain of shea in Niger State, Nigeria. One hundred and forty respondents were selected through a multistage random technique. Data were analyzed using value addition method and descriptive statistics. Findings revealed that there are four key players in the shea value chain, namely the sole picker, the processor/picker, butter marketer and the retailer. Regarding value addition, it was found that the sole picker adds a value of ₦250 (3.10%), the local processor, adds a value of ₦1550 (19.38%), the shea butter marketer adds ₦600 (7.70%) and the retailer adds a value of ₦5600 (70%). Furthermore, findings revealed that the retailer has the highest margin of ₦3460 (70.47%) while the processor has a margin of ₦1050 (21.38%). The sole picker has the lowest margin of ₦150 among players in the chain. However, findings reveal that, the picker has a higher margin when he doubles as a processor. Since majority of the pickers and processors are women, empowerment of the female gender can be enhanced through interventions in the shea value chain. Therefore, this study recommends a gender-based study of the shea value chain in the study area which will further reveal potentialities for empowering women and the household in the study area. Furthermore, to give leverage to the sole picker in terms of the size of market margin attracted, it may be expedient to empower the sole picker to get involved in the processing of the nuts.
