Summary: This study examines the influence of tree cover on crop yield in a landscape dominated by Vitellaria paradoxa and Parkia biglobosa in central Burkina Faso. The results show that tree canopy cover and tree density inside the fields tend to decrease crop yield due to competition, but when considering the surrounding landscape, they exert an opposite effect because of their buffering effects. Soil properties have limited effects on crop yield. Farmers in this area can optimize sustainable yields by managing the tree cover.

Summary: SDMs have been widely used for forest management planning and biodiversity conservation globally. This study used SDMs to analyze the spatial distribution of tree species diversity in Faidherbia albida parkland in Central Senegal. The results showed that different tree species have different adaptability to SDM algorithms, and using multiple modeling techniques can improve SDM performance. The study also found that tree species diversity is related to landscape characteristics and human impact.

Summary: The diverse and multi-component nature of traditional agroforestry systems (AFS) provides unique advantages in agricultural production and ecosystem services. The adoption of poplar-based AFS in the Indo-Gangetic region of India has improved the economic status of farmers. A study on the effect of poplar windbreak on wheat intercrop and soil nutrient status suggests that poplar trees have a significant impact on wheat yield and contribute to soil nutrient availability.

Summary: Alley cropping is considered a promising adaptation strategy in the face of more frequent drought events in Mediterranean regions. However, the presence of trees can limit crop productivity, especially under dry conditions. This study suggests that agroforestry systems may exhibit higher resilience in the case of early drought conditions.

Summary: Soil water and nutrients are the main limiting factors for the stable development of alley cropping systems in the Loess Plateau of west Shanxi, China. The study found that water and fertilizer coupling regulation can improve soil water and nutrient distribution, as well as increase crop yield and productivity. A combination of 50-65% field capacity and 70% empirical fertilizer application is the optimal irrigation and fertilization management for this system.

Summary: This study assessed the land use and land cover dynamics and traditional agroforestry practices among smallholder farmers in the Wonchi District of Ethiopia. The results showed an increase in agroforestry cover and a decrease in forest, cropland, water body, and shrub areas, primarily due to settlement expansion and changes in land policies.

Summary: Imprecise irrigation hinders the sustainable development of the fruit tree-crop intercropping system in the Loess Gully Area of China. Drip fertigation was applied for two years as part of an apple-soybean intercropping system to optimize local water and nutrient management patterns. The effects of different drip irrigation and fertilizer levels on photosynthetic characteristics, soil nutrients, and their interspecific competitions were studied. The results indicate that a combination of irrigation at 80% of field capacity and 92 kg.ha(-1) nitrogen fertilizer application is optimal for the system.

Summary: The transition from conventional arable to silvoarable systems can enhance ecosystem services delivery. However, it is crucial to assess crop yield under agroforestry conditions to ensure the reliability of these systems and expand our knowledge to support their design. This study investigates the effects of poplar short rotation coppice rows on soybean and sorghum productivity in a 2-year rotation within an alley-cropping system, highlighting the importance of light availability and soil characteristics on crop performance. Our results show that light is crucial for sorghum cultivation, while soybean is also affected by soil moisture and water retention capacity, emphasizing the need to consider different crop agronomic performance and tree row harvest cycle in the design of an SRC-based agroforestry system.

Summary: Land degradation and soil acidity are major challenges for crop production in the Ethiopian highlands. Farmers have developed an alternative agroforestry system by integrating Acacia decurrens into their landscapes, which has shown significant improvements in soil properties. The expansion of these plantations has been driven by the income generated from charcoal making, and the intervention has resulted in increased soil pH, soil organic carbon (SOC), cation exchange capacity (CEC), and available soil phosphorus (Bray-P). The integration of A. decurrens-based agroforestry practices can improve livelihoods by restoring degraded lands, improving income generation, and sequestering carbon.

Summary: Land use change has a significant impact on soil properties. This study investigated the variation in soil physicochemical properties across different land use practices and found significant differences between them. Some land use systems, such as enset agroforestry, improve soil properties while others, like cereal production, degrade soil. Therefore, implementing appropriate soil management strategies is crucial to mitigate soil nutrient loss.

Summary: This study investigated the response of grain sorghum to nitrogen, phosphorus, potassium, sulphur, and zinc fertilizers, as well as the influence of different landscape positions on fertilizer response and yield variability. The results showed that the response to fertilizer application differed across landscape positions, with foot slopes exhibiting the highest response. Additionally, the combined application of nitrogen and phosphorus fertilizers, landscape position, and the interaction between fertilizer application and landscape positions significantly affected sorghum yield.
