“…They also observed that SOC constituted the greatest pool of C in these systems and that this C pool did not vary with the system's design. Noumi et al (2018) compared the global C storage of Eucalyptus afforested plots with traditional Savannah in Cameroon. They observed that Eucalyptus stands stored more C than traditional Savannahs especially the oldest Eucalyptus stands.…”

“…Soil organic matter content is crucial for soil health, acting as a source of energy for soil organisms and influencing their diversity and various biological functions" [16]. "Studies in traditional savannahs and agro-silviculture systems demonstrate that carbon storage is larger in tree stands, emphasizing the importance of trees in carbon stocking and nutrient cycling" (Noiha et al, [17], Dhaliwal et al, [18]. "The amount of organic matter in the soil is a crucial ecological element that influences the viability of terrestrial ecosystems, affecting the physical, chemical, and biological properties of the soil.…”

This study investigates the impact of a Melia dubia-based agroforestry system on soil properties in Gillan Khera, Fatehabad district, located in the semi-arid region of Haryana. Soil samples were collected from a 7-year-old plantation with a 3m × 3m spacing, where three oat varieties were intercropped. Parameters such as pH, electrical conductivity (EC), organic carbon, soil moisture, and available nitrogen, phosphorus, and potassium were analysed at depths of 0-15 cm and 15-30 cm. Results revealed a decrease in soil pH and EC under trees, with values decreasing from 8.09 to 7.89 and 0.46 to 0.44 dSm-1, respectively. However, intercropped conditions exhibited higher levels of nitrogen (131.38 kg/ha), phosphorus (16.00 kg/ha), potassium (301.10 kg/ha), and organic carbon (0.46%) at both soil depths. Additionally, there was more soil moisture under the plantation. These findings suggest a positive correlation between tree growth and soil health. The study recommends the Melia dubia-based agroforestry system as a promising approach for enhancing soil fertility and promoting environmental sustainability.

“…The degradation of forest ecosystems is a cause of the reduction in biodiversity in the world [2,3,4]. The Changes in the floristic composition and vegetation structure show this degradation [5]. These ecological disturbances, which affect the biological resources and the potentialities of the land, result in the deterioration of the standard of living of the populations.…”

This study aimed to assess the floristic composition, vegetation structure and species associations of Cashew agro-ecosystems in the North region of Cameroon. The data were collected in 100 m x 20 m transect methods. An analysis of the data collected in the field was conducted around the diversity and richness of the flora, but also the structure of Cashew agro-ecosystems. For the analyzes of vegetation structure, tree density, basal area and biovolume were calculated. The inventory included trees with a dbh greater than or equal to 5 cm on an area of 1 ha per plot. The experimental device installed is a complete random Fisher block with five repetitions. A total of 7849 individuals in 17 families, 20 genera and 38 species were recorded. Species Important value of vegetation cover indicated that Diospyros mespiliformis, Anogeissus leiocarpus, Annona senegalensis and Terminalia laxiflora are the most represented. Combretaceae are the most ecologically important families. Additionally, the grouping of species into four subdivisions showed that the Shannon diversity index varies from 2.18 ± 0.09 -3.47 ± 0.17 bits, Pielou index vary from 0.98 ± 0.01 -0.99 ± 0.01, Simpson's index ranges from 0.70 ± 0.18 -0.93 ± 0.11, density ranges from 102 ± 1.92 -128 ± 6.36 indiv/ha, basal area ranges from 2.02 ± 0.31 -12.68 ± 2.01 m²/ha, biovolume ranges from 11.58 ± 1.29 -68.03 ± 13.21 m 3 /ha. The Sörensen similarity index is very high with floristic affinities greater than or equal to 90%. The diameters and heights structure show a predominance of young individuals for the diameter and height classes on all plots. The most represented species associations are legumes (Arachis hypogeae: 40.54%) and native fruit trees (Vitellaria paradoxa: 15%). These results show the contribution of Cashew agro-ecosystems in biodiversity conservation.
