Landslides continue to occur in the Elgon region despite interventions such as tree planting initiatives aimed at restraining them. The current study assessed the mechanical properties of six selected agroforestry tree roots on slope stability with a keen focus on root tensile strength, soil shear strength, and index of root binding. A standard deviation ellipse method was applied to model the spatial distribution patterns of selected agroforestry trees. Tree-landslide relationship was tested using the Pearson correlation method while root tensile and soil shear strength with a one-way (ANOVA) and descriptive statistics respectively. Species distribution results indicate a high dispersion rate of Croton macrostachyus and Markhamia luteaacross the study area and high concentration of Albizia coriaria downstream. A weak negative correlation (r = -0.20 < 0.01) was reported between diameter at breast height and landslide size. Tensile strength results observed a significant difference among species with (F (5, 573) = [18.161], p < 0.001) and Grevillea robusta (3.02±1.217kg/mm²), Albizia coriaria (2.53±1.382kg/mm²), and Markhamia lutea (2.28±1.01kg/mm²) as the best performers. The best shearing species was Albizia coriaria with average shear strength (52.46±10.24) kpa followed by Markhamia lutea (50.70±15.47) kpa. The Eucalyptus spp. on the other hand underperformed with average shear strength of (46.75±12.92) kpa. In conclusion, the presence of trees reduces landslide risk in an area and DBH is a very important guiding factor. Grevillea robusta, Albizia coriaria, andMarkhamia lutea emerged as best performers in terms of root tensile strength and soil shear strength hence their suitability for enhancing slope stability. However, Eucalyptus Spp., which is widely favoured in the region for its rapid growth was the worst performer with very low shear strength. Therefore, careful consideration of the tree characteristics is essential during promotion campaigns for slope stability in fragile environments.

“…[24] Previous literature reported that some of the cellulosic fibers such P. bauhinia fibers (1460 kg/m 3 ), Trachelospermum jasminoides fibers (1398 kg/m 3 ), and A. saman fibers (1450 kg/m 3 ) also own higher density than VMF. [14,25,26] This lesser density of VMF increases the suitability to develop lower weight applications. The diameter, density and chemical fractions of VMF and other plant fibers are synopsized in Table 1.…”

“…The kinetic activation energy of the numerous fibers, specifically A. saman fiber (64.01 kJ/mol), arial root F. amplissima fiber (66.25 kJ/mol), C. nucifera peduncle fiber (70.23 kJ/mol), and P. bauhinia fiber (90.58 kJ/mol) were already discovered by the various researchers. [14,18,26] Generally, the kinetic activation energy of the wooden materials are expected between 60 and 170 kJ/mol. All the findings of the thermal analysis of VMF were conveyed that VMF is the appropriate fiber to manufacture the fiber reinforced plastics.…”

This article is designed to examine the aptness of Ventilago maderaspatana fiber (VMF) as reinforcement in polymer composites. A significant quantity of cellulose fraction (56.12 ± 5.42 wt%) in the VMF was estimated via chemical analysis. The X-ray diffraction analysis identified the presence of cellulose type-I and peak cellulose type-IV in the VMF, and it quantified the crystallinity index (25.88%) and crystalline size (26.12 nm) of the VMF. Various chemical functional groups in the VMF were categorized with the help of Fouriertransform infrared spectroscopic analysis. The thermal degradation behavior of the VMF was investigated with the help of thermogravimetric analysis, and it determined the thermal stability (200 C) and kinetic activation energy (62.46 kJ/mol) of VMF. The scanning electron microscopic and energy dispersive X-ray spectroscopic analysis revealed the existence of contaminations, hemicellulose and lignin on the outer layer of VMF, and it was confirmed by atomic force microscopic analysis. The lower density (1236 ± 18.42 kg/m 3 ) and better tensile strength (383.7 ± 16.07 MPa) of the VMF enabled the possibility of use as reinforcement in fiber reinforced plastics.

This research investigated the scope of using a fiber harvested from Mucuna atropurpurea (MAF) plant as reinforcement in fiber-reinforced plastics. An optical microscope and a pycnometer were used to calculate the diameter (289 ± 21 μm) and density (1082 ± 29 kg/m 3 ) of the MAF. Using chemical compositional analysis, 58.74 ± 5.74 wt% cellulose and 16.31 ± 3.21 wt% hemicellulose, and 14.22 ± 3.36 wt% lignin and 0.38 ± 0.08 wt% wax components were found in the MAF. Numerous chemical stretching in the MAF were checked using Fourier transform infrared spectroscopy. Briodo analysis (68.08 kJ/mol) showed the kinetic activation energy of the MAF. Surface morphological inspections suggested surface treatments of MAF due to contaminations and wax on the fiber surface. The statistical analysis conducted for determining the tensile properties of MAF revealed that MAF is a suitable candidate to produce fiber-reinforced plastics. Characterization of MAF-reinforced polyester composites showed that 40 mm fiber length and 30 wt% fiber enhanced tensile strength (109.51 ± 2.1 MPa), flexural strength (156.62 ± 3.1 MPa), and hardness (94 ± 4 HRRW). Fractography images of composites with fiber pull-outs in the MAF-reinforced plastics were taken for analysis. Less cavities and voids in the 30 wt% MAF-reinforced composites were found along with reduced water absorption.
