“…Indeed, there is a marked improvement in soil moisture and soil fertility under the shea tree canopy [1]. The rainfall is, in part, intercepted by the tree canopy and the amount of water reaching the soil under the canopy may not be sufficient, given that the tree and the underlying crop absorb more water than the crop alone [11]. But, the canopy also helps conserve use of soil water [12], as temperatures are moderate under shea trees due to shading [1].…”

“…The advantage of tree-crop intercropping therefore lies in maintaining soil fertility and the sustainability of farming systems [4], especially since many authors have found that shea trees are excellent fertilizers thanks to their leaf biomass. Indeed, studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15] report that trees in fields have positive effects on soil fertility, and especially on levels of organic matter and nitrogen; their areas of influence represent "islands" of fertility in semi-arid zones. Similarly, the work of [16] in Saponé in Burkina Faso showed that mulch from shea leaves induced a 120% increase in millet grain yields and a 43% increase in its total dry matter.…”

This study evaluates the productivity of cotton and sorghum in a shea-based agroforestry system in northern Benin. Tomboutou and Gounarou villages were respectively selected in the shea parklands of Bembèrèkè and Kandi. Within each parkland and village, three classes of tree crown diameter for shea trees (4 -8 m, 8 -10 m and <10 m), were defined after the inventory phase. In each class of crown diameter, three trees intercropped with cotton and sorghum were randomly selected among the 18 to 21 farms in each of the two village territories. The crops were planted in accordance with the technical procedures recommended by the national agricultural extension service. The following data was collected for sorghum and cotton on 1 m² area under the crown and outside the crown, in the four cardinal directions of each sample tree: crop height, fresh biomass per crop and buds per cotton plant. Data analysis revealed a very significant difference in the variables (height of sorghum and cotton, biomass of cotton and sorghum, number cotton buds) between the areas under the crown and those outside the crown (P < 0.01). The productivity variables for sorghum, i.e., average plant height and average biomass, dropped by 9.75% and 29.31%, respectively, when planted under the crown. Cotton under the crown was 6.58% shorter compared to plants outside the crown. Average bud production and average fresh biomass for cotton plants was 13.06% and 36.06% less, respectively, when planted under the crown of shea trees.

“…Au Bénin, Gnanglè et al (2012) ont rapporté l'importance de ces parcs à karité et à Néré dans les paysages agrosylvicoles comme sources de revenus pour des populations locales et d'un intérêt pour la conservation de l'environnement. D'après Boffa et al (2000) et Kristensen et Balslev (2003), les principales cultures vivrières et de rente associées aux arbres sont le petit mil, le sorgho, le maïs et le coton. En plus de ces cultures, il faut inclure le niébé et l'arachide.…”

“…Maize and rice, which require high intensity light conditions for increased crop productivity, were widespread in the study area. Thus, low numbers of scattered trees in parklands will be bene cial for grain yield due to increased solar radiation (Boffa et al, 2000;Liu et al, 2014;Yang et al, 2019). In contrast, shade tolerant species such as pepper and yam were predominantly cultivated on farms located in Site 1 where V. paradoxa and total woody plants exhibited aggregate spatial patterns.…”

Spatial pattern and density of woody plants in an agroforestry parkland in a West African savanna

Agroforestry parklands are an age-old traditional land use practice that integrates crop cultivation under scattered woody plants. This practice is widespread in West African savannas providing many essential ecological and socio-economic benefits to people such as food, fuelwood and medicine. Currently, parklands are decreasing due to changes in agriculture and land use practices, often associated with human population growth. Understanding spatial patterns as well as identifying reliable methods of sampling to estimate density of woody plants is necessary for sustainable management of parklands. In this study, five relatively easy-to-use plotless sampling methods were applied to estimate density of woody plants using field and simulated datasets with known spatial patterns from field assessments. Results of spatial indices tests indicated that woody plants in parklands exhibited two spatial patterns: i.e., aggregate and random, the latter being the dominant pattern observed in field datasets. Based on relative measure statistics (i.e., RRMSE and RBIAS), the ordered distance (OD), point-centered quarter (PCQ) and closest individual (CI) methods performed well when woody plants were located in a random pattern while the variable area transect (VAT) method was better at estimating density under patterns of spatial aggregation. Overall, OD and VAT methods are recommended for density estimation in parklands because they are relatively more accurate, less biased, practical and computations are easy to undertake.
