Summary: This study evaluated the taxonomy, diversity, and distribution of rhizobial genera in soils from the tropical savannah zones in Northern Cote d'Ivoire. It revealed that Bradyrhizobium genus dominates in these soils and suggested that the V5-V7 region may be suitable for differentiating rhizobia at the genus level. These findings could be valuable for future rhizobial microbiome explorations and land-use decision-making.

Summary: Climate change models predict an increase in climate variability, impacting smallholder crops in West Africa. Conservation Agriculture systems can help mitigate yield loss, as shown in this study evaluating upland rice-based CA systems in the Bouake region. Results indicated that CA systems had higher rice yields over time, particularly in situations of water stress. Further research is needed to reduce transition periods to CA systems for adoption by smallholder farmers.

Summary: The sustainability of a women's group-based NSA project in Cote d'Ivoire was examined 18 months after the project ended. Results showed that gardening groups remained functional but with lower productivity, while village-level poultry activities had mostly ended due to mortality and limited expertise. There was a shift towards individual production approaches and more marketable products, moving away from nutrient-dense ones promoted by the project.

Summary: In central Cote d'Ivoire, the low fertility of savanna soil has resulted in farmers preferring wooded areas, which poses pressure risks to Lamto Scientific Reserve. This study suggests that abandoned termite mounds can be used as a cultural amendment to restore soil fertility, as they are more stable and fertile than adjacent soils.

Summary: The introduction of Caragana korshinskii on the Loess Plateau grassland can increase vegetation cover, soil nutrient content, and grassland productivity, while also maintaining species richness and evenness. This suggests that C. korshinskii is the preferred legume species for grassland restoration in the area.

Summary: Water erosion accelerates soil degradation through land use, land cover, and climate change. Accurate modeling of soil erosion is crucial for assessing environmental variables and formulating policies to prevent land degradation. The study reveals that integrating RUSLE2 with LSU can provide more accurate estimation of regional soil erosion, showing the importance of considering vegetation cover changes and spatial factors in soil erosion modeling.

Summary: This study aimed to determine the potential factors influencing farmers' satisfaction with Input Credit (IC) based on farmers' socio-economic data. The results revealed that annual production required, number of years of IC use, training programs for farmers, farm size, input price, and age significantly influenced farmers' satisfaction.

Summary: This study aims to investigate the impact of different agricultural practices on phenotypic insecticide resistance and associated molecular resistance mechanisms in Anopheles gambiae s.l. The results show that mosquito populations from all agricultural sites were resistant to several insecticides, with variation in the frequency of resistance mutations and gene expression levels. The findings suggest that agricultural practices might have a role in shaping insecticide resistance profiles in malaria vectors.

Summary: This review evaluates the potential and limitations of biochar in Sub-Saharan Africa (SSA) and discusses its potential benefits in agriculture and the environment. The abundant crop supplies in Cote d'Ivoire present a significant opportunity for biochar production. Biochar has the potential to improve soil fertility and crop productivity, reduce greenhouse gas emissions, and remediate polluted water and soils. However, there are various challenges that need to be addressed, and policies and standards need to be developed to promote the use of biochar in SSA.

Summary: In sub-Saharan Africa, unreliable rainfall and depleting soil fertility pose significant challenges to food security. This study evaluates soil suitability and fertility constraints, and discusses the influence of soil properties on maize production. The results indicate variations in soil texture and low concentrations of organic carbon and base cations. Soil management measures are needed to increase maize yield in the study area.

Summary: The study found that complex tree stands can mimic the natural forest in terms of soil microbial activity and organic status, while monocultures lead to carbon loss. The mixture of Teak, Gmelina, Terminalia ivoriensis and Terminalia superba showed no significant difference in soil attributes compared to the natural forest.

Summary: This study investigated the carbon and macronutrient cycling in cocoa and teak plantations in Central-West Cote d'Ivoire, revealing that cocoa plantations had lower inputs of carbon and nitrogen compared to the forest, while teak plantations had similar phosphorus inputs and greater potassium inputs. Cocoa leaf litter decomposed at a rate similar to the forest but faster than teak, with significant declines in soil carbon mineralization rate and mineral nitrogen concentration observed in both tree plantations. Teak was identified as a good candidate for shade to compensate for the deficit in carbon and nitrogen inputs exhibited by cocoa relative to the forest.

Summary: The study revealed that soil microbial activity and MBC/SOC ratio decreased in invaded savanna sites compared to natural forest sites, while carbon mineralization, enzymatic activities, qCO(2), and available N and P concentrations significantly increased. The invasion effect was found to be twice as high in savanna compared to forest.

Summary: Identifying and scaling up agricultural practices that promote atmospheric carbon transfer into the soil are crucial for combating climate change. A study in Cote d'Ivoire found that Chromolaena odorata, a plant commonly known as wild sunflower, has a high capacity to store soil organic carbon and enhance soil fertility in fallow management. Additionally, wild sunflower can thrive in arid environments, making it beneficial for both agriculture and climate resilience.

Summary: Forest-dependent, tropical island endemic birds are at risk of extinction, but remain understudied. A camera-trap survey in Guadeloupe revealed that the Ruddy Quail-Dove is scarce compared to the Bridled Quail-Dove which is mainly found in tropical rainforests, while the Zenaida Dove is more frequently observed in flooded forests and dry forests. Temperature negatively affects the abundance of Bridled Quail-Dove, and Zenaida Dove has significantly lower abundance in tropical rainforests.

Summary: Substantial areas of agricultural lands in Sub-Saharan Africa have been invaded by Chromolaena odorata (Asteraceae), leading to changes in diverse AMF community attributes and improved soil phosphorus availability. The invasion resulted in noticeable changes in AMF community composition, with lower richness and different composition in the invaded sites compared to non-invaded sites. The invaded sites showed higher total and healthy spore densities, increased root colonization intensity, and higher soil available phosphorus compared to natural ecosystems.

Summary: Plantain (Musa paradisiaca AAB) is a crucial crop in the tropics, particularly in the Caribbean, but pests pose a significant challenge to its production. This study aimed to investigate the relationship between cropping systems, soil quality, and pest susceptibility in plantain plots. The results showed that agroecological systems with improved soil quality had better regulation of plant-parasitic nematodes and achieved similar crop production levels to conventional systems without the use of pesticides.

Summary: This study evaluates the impact of two agroecological practices on soil microbial communities, finding that both systems have a positive impact on beneficial soil bacteria. The study examines the influence of these practices on the composition and diversity of soil bacterial and fungal communities. Results show significant changes in microbial communities in both systems compared to bare soil, particularly for specific phyla. The agroecological systems enhance soil microbial diversity and promote the development of beneficial bacteria.
