“…These systems consist of either monoculture plantations in which trees of one species are intercropped with some remnants of the original vegetation, or silvopastoral systems, where grass is grown as pasture for sheep to graze. Both are common and are considered sustainable alternatives for tropical regions (Jack et al, 2021; Pulina et al, 2018), particularly for Latin America and the Caribbean, where large areas of tropical forest have been transformed into pasture grassland (Meza‐Herrera et al, 2022).…”

Numerous works have reported the impact on soil properties and microbial communities of intensive soil management, but very little is known about the impact caused by traditional agroforestry systems carried out by smallholders. To investigate whether the different smallholder's management between a monoculture plantation of Cordia dodecandra trees and a Silvopastoral system has led to a divergence in these ecosystems, soil properties, as well as soil and Cordia dodecandra rhizosphere microbial communities were analysed by MiSeq amplicon sequencing. The main findings were (i) Large variation in the soil properties of the Silvopastoral system suggests that it has a greater heterogeneity; (ii) Organic carbon, organic matter, carbonates, nitrogen, inorganic phosphorous and calcium, was significantly higher in the soil of the Silvopastoral system. (iii) The relative abundance of the major prokaryotic orders in soil and rhizospheres displayed small differences between the two agroforestry systems, and diversity indexes were slightly higher in the Silvopastoral system. (iv) The fungal orders Hypocreales and Pleosporales were more abundant in the Silvopastoral system than in the monoculture. Other evaluated parameters showed only minor or no difference. Thus, the main conclusion is that these soils have diverged in some properties and fungal orders, but not in their prokaryotic communities. To our knowledge, this is the first report on the divergence in soil properties and microbiota of these two extended smallholder agroforestry systems and therefore can serve as reference for future works.

“…Many interventions in the livestock and food production sector in developing countries like Nigeria sought to transform smallholder operations into intensive ventures [18]. One of the intervention programs that were able to boost local productivity and farmer's capacity, is the Federal Government of Nigeria Commercial Dairy Project, evidently increasing the output of milk and milk products in regions where the program operates [12].…”

This study focused on antibiotic resistance genes as emerging contaminants with potential global human health implications. Intensive livestock farming has been identified as a major contributor to the spread of resistant bacteria and genes. The study examined antimicrobial-resistant Escherichia coli and tetracycline-resistant genes in raw milk from commercial dairy farms in Kano State. Out of 300 registered farms, 54 (18 %) were purposively sampled for the study. A total of 313 milk samples were collected and processed through enrichment and inoculation on selective media for Escherichia coli isolation. The antibiogram pattern of the isolated Escherichia coli strains was assessed using the disk diffusion method. The results revealed resistance to various antimicrobial agents, with no resistance to quinolones but high resistance to ampicillin (100 %), erythromycin (73.3 %), and tetracycline (46.7 %), among others. The multiplex polymer-ase chain reaction was conducted on all Escherichia coli isolates to detect tet genes (tet A, B, C, D, and M), and one isolate carried the tet M resistance gene, while six (40 %) others carried the tet A resistance gene. The study concludes that a significant proportion of the cultured Escherichia coli strains were resistant to one or more tested antibiotics, indicating a potential public health threat associated with Escherichia coli contamination in raw milk. We recommend implementing robust regulatory policies governing the use and sales of antimicrobials in animal production. Furthermore, we suggest further investigation into other resistant genes that these isolates might carry to better understand the extent of antibiotic resistance in the region.
