“…Many of the advantages of trees on a farm landscape are similar to those of trees in a neighbouring forest, but they also have certain special advantages that can be tapped into through the development and management of agroforestry (the integration of woody plants into farming systems) [27]. For instance, trees cultivated on farms for their fruit or wood generate a substantial amount of revenue for the nearby farmers [28], often accounting for more than 17% of their annual income, while rural households only generate 6% of their income from trees. Households may receive crucial nutrients from these trees [29], such as vitamin C, which can assist in meeting the minimal daily requirements for micro-nutrients [19], [30].…”

Many developing countries, especially those in sub-Saharan Africa, have focused on improving agricultural production at the farm level. Governments have implemented agricultural policies and acts to support various initiatives aimed at generating secure and affordable food for low- and middle-income populations. However, these policies can sometimes lead to more homogeneous landscapes, reducing the diversity of accessible food. As global demand for food increases, farmers are expanding their crops and livestock into new areas. Yet, the inclusion of trees in agricultural landscapes is crucial for maintaining diversity. The objective of this study was to synthesize the benefits of incorporating trees in smallholder farming systems in sub-Sahara Africa. Therefore, the study found increasing evidence that trees can enhance welfare among rural farming households, particularly in sub-Sahara Africa. Incorporating trees into agricultural landscapes offers numerous benefits, including improved household nutrition and food security through enhanced crop yields and diversified diets. These practices also support income generation and livelihood diversification, providing farmers with additional sources of revenue. Moreover, trees contribute to environmental benefits and ecosystem services such as soil fertility, water retention, and carbon sequestration, which are crucial for climate change adaptation and resilience. Additionally, integrating trees fosters the preservation of cultural and traditional knowledge, while promoting biodiversity conservation and ecosystem restoration, ultimately creating a more sustainable and resilient agricultural system. Moreover, integrating trees into farming landscapes can help address Sustainable Development Goals (SDGs) 1 and 2—' No Poverty' and 'Zero Hunger'—by increasing crop yields. This study recommends enhanced awareness campaigns for incorporating trees into agricultural landscapes.

“…The texture of the soil has been changed to loamy by manual deposits of alluvial soils [23]. However, the available phosphorus content of the soil was low and other elements were almost at satisfactory level [24].…”

“…Among the treatments, the highest exchangeable K was recorded in W 4.5 N 100 +PM (0.19 meq/100 g soil) and the lowest was found in both CC+N o and CC+N 25 (0.08 meq/100 g soil) treatments (Table 3). Crop removal and losses through runoff may be attributed to the lowest exchangeable K in the control plot, whereas, the increase in exchangeable K in plots under the three different alley widths might be due to the return of K via tree pruning and leaf litterfall to the soil surface [42] and an increased exchangeable K was observed under G. sepium [24].…”

Soil health needs to be improved for the sustenance of a productive agriculture and sound environment where alley cropping system might play a vital role. The study was composed of two factors viz. three alley widths of Gliricidia sepium (3.0, 4.5 and 6.0 m), and five nitrogen levels (0, 25, 50, 75 and 100% of the recommended dose) along with pruned materials in a split-plot design with three replications. The soil chemical properties were examined in alleys of Gliricidia sepium tree over two consecutive seasons. Results displayed that pruned materials (PM) of G. sepium increased the soil pH, organic carbon (OC), total nitrogen (N), available phosphorus (P) and sulfur (S), exchangeable calcium (Ca), magnesium (Mg), potassium (K), and cation exchange capacity (CEC) of soil in different alley widths compared to the control. However, alley width 3.0 m and 100% N along with PM displayed the maximum OC (0.94%), total N (0.21%), available P (16.26 ppm), exchangeable Ca (2.54 meq/100 g) and Mg (0.90 meq/100 g), while maximum exchangeable K and CEC were noted in alley width 4.5 m and 100% N along with PM. The above results explicated that the improvement of the soil chemical properties by using pruned materials of G. sepium in alleys can be a promising option for uplifting the soil health condition as well as sustainable agricultural practices.

“…The vegetable hummingbird is also known as Bakphul in Bangladesh. These two species biologically fix N, can withstand repeated pruning, produce a large amount of pruning materials and nutrients, and are relatively long-lived [9,10]. During the evaluation of the alley cropping system in a flat upland ecosystem, the assessment of commercially grown vegetables on that land type should be given emphasis.…”

The study was conducted at the Agroforestry Farm of Sylhet Agricultural University from October 2020 to March 2021 to evaluate the growth and yield performance of carrot and determine soil fertility status during the hedge establishment period of alley cropping. Hedges for alley cropping were established using ipil-ipil (Leucaena leucocephala) and vegetable hummingbirds (Sesbania grandiflora) tree species. The experiment was laid out in a randomized complete block design (RCBD). During the hedge establishment period, the carrot was cultivated in the alley of the hedgerow using four different treatments with three replications. The treatments were T0 (No application of fertilizer and pruning materials), T1 (application of recommended fertilizer dose), T2 (application of half dose of the recommended fertilizer + pruning materials), and T3 (application of pruning materials). The results exhibited that growth parameters, viz. plant height (cm), leaf number per plant, root length (cm), and root diameter (cm) of carrot were almost similar in all treated plots, except control (T0). The carrot yield was statistically similar in all fertilizer and pruning materials treated plots, but it was drastically reduced in the control plots and decreased by about 40-45% compared to fertilizer and pruning materials applied plots. During hedgerow establishment, soil pH among different plots has not changed significantly compared to the initial field, but organic matter (OM), nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) in different alleys found to be increased significantly in treatment T2 and treatment T1 after carrot cultivation. Improvement in soil fertility was also found in the alleys between the hedgerows of ipil-ipil and vegetable hummingbirds when only pruning material was applied to the soil. Therefore, an alley cropping system with Leucaena leucocephala and Sesbania grandiflora may enhance the yield performance of carrot and organically improve soil fertility during the hedge establishment period.
