Hydraulic redistribution (HR) by woody vegetation has been proposed as a potential water source for crops in intercropped systems. The native shrub, Guiera senegalensis J.F. Gmel, grows the fields of farmers across African Sahel and shown profound yield benefits to associated pearl millet (Penisetum glaucum) crops, especially drought years. We tested whether this benefit was result shrubs performing hydraulic with using some HR water. During an experimentally imposed drought, enriched...
Agroforestry systems combining indigenous shrubs and crops are recognized as promising ways of restoring degraded soils improving agricultural yields in the Sahel. Research is attempting to optimize these maximize their benefits. In this context, comparative effect optimized (OSS) traditional (TMS) Guiera senegalensis management on performance groundnut(Arachis hypogaea L.) millet(Pennisetum glaucum was studied Meckhe zone from 2019 2022 under farmer conditions. OSS involves increasing...
Senegalese agriculture relies heavily on peanut cultivation, but agricultural intensification has led to soil degradation and a decline in fertility. Soil organic carbon (SOC) is key indicator of quality, influencing its structure However, conventional SOC analysis methods are costly time-consuming. Infrared spectroscopy (NIRS MIRS) offers fast non-destructive alternative, allowing estimation based the soil’s spectral properties. The study, conducted Peanut Basin, involved 240 samples at two...
A major limitation for crop productivity in degraded Sahelian soils is the lack of organic inputs. Piliostigma reticulatum (DC.) Hochst and Guiera senegalensis J. F. Gmel. are unrecognized unmanaged shrubs Sahel that coexist with crops have potential to provide significant amounts inputs improve soil quality. However, conventional management involves coppicing burning aboveground biomass every spring before plantings. Therefore, objective this study was develop fundamental microbial...
Strategies that strengthen and use biodiversity are crucial for sustained food production livelihoods in semi-arid West Africa. The objective of this paper was to examine the role sustaining diverse forms multifunctional farming practices while at same time providing ecological services subsistence-oriented families region study through mechanisms as (a) crop species diversification, (b) management spatial heterogeneity, (c) diversification nutrition-sensitive landscapes. Our analysis shows...
Piliostigma reticulatum (DC.) Hochst., an indigenous shrub, forms important vegetative component of parkland cropping systems in the Sahel; however, its biophysical interactions with soil and crops are not well understood. Therefore, objectives were to determine impact P. , under varying fertilizer rates, on crop yield response nutrient dynamics. The experiment had a split‐plot factorial design, where main plot was shrub (presence or absence) subplot rate (0, 0.5, 1.0, 1.5 times recommended...
In Senegal, numerous initiatives exist to cultivate Jatropha curcas L. (JCL) trees as a multipurpose energy crop, including for fuel. Thus, research on this drought-resistant shrub has been predominately focused biofuel production from its seeds, while potential carbon (C) sequestration, which could be valuable in sink projects (i.e., afforestation, reforestation) under the Clean Development Mechanism (CDM) of Kyoto protocol, largely unstudied. This study was carried out Senegal's Peanut...
The indigenous shrub, Guiera senegalensis , coexists with crops to varying degrees in farmers' fields throughout the Sahel, little known about its biophysical and ecological interactions soils crops. Therefore, objectives were determine effect of presence or absence shrubs under rates fertilizer on: (i) crop growth yield, (ii) soil nutrient dynamics. An experiment from 2004 2007 was conducted northern Senegal where G. dominates that had a split‐plot factorial design. main plot rate (0, 0.5,...
Located within the Sahel region, Senegal faces several agricultural production challenges. Limited rainfall, poor soil fertility, and insufficient agronomic inputs all contribute to low pearl millet [ Pennisetum glaucum (L.) R. Br.] yields. This study was initiated assess potential for increasing yields through intercropping (living cover) mulching (desiccated practices. During 2013 2014 growing seasons, intercropped with cowpea Vigna unguiculata Walp.], mungbean radiata Wilczek], or grown...

L’approche rétrospective adoptée s’appuie sur comparaison entre les signatures spectrales dites « référence » issues des vérités terrain celles classes résultant classification multispectrale non supervisée images prises dates antérieures. Le résultat est principales catégories d’occupation chacune étudiées leur évolution dans le temps. Ont ainsi...
