Nonetheless, this undiluted practice is inadequately assessed and documented, which leaves the development of locally evolved technologies baseless. In light of this, this study was conducted to assess traditional farming systems, management practices, and benefits to rural livelihood diversification. Three representative sites were chosen using a representative sampling technique. In total, 355 households were selected from the study sites using a simple random sampling technique. Semi-structured interviews, direct field observations, and key informant interviews were used to collect data. Results showed that households managed their farmlands, categorizing them into home-garden, extended home-garden, regular farmland and shared cropland, mostly using indigenous knowledge. The overwhelming majority of households (96.3%) used various types of multiple cropping systems: traditional agroforestry (98.2%), mixed cropping (54.4%), intercropping (30.7%), crop rotation (6.2%), and relay cropping (4.2%). In such multiple cropping systems, households took into account morphological, physiological, ecological, and socioeconomic benefits in choosing appropriate crops that can be grown simultaneously. In order to further diversify food and income sources and make the local food system more climate-resilient, the traditional agroforestry landscape included both food and cash crops, with trees planted alongside coffee, enset, khat and other annuals. The compatibility of crop components, their organization, and the availability of appropriate varieties of crops were critical factors in the success of multiple cropping systems. Traditional knowledge on crops and management practices allowed farmers to have different settings for rotation, intercropping, and agroforestry systems. As well, the spatial and temporal portfolios that traditional farming systems offer promoted ecological functions like soil water storage, nutrient cycling, and pest and climate change regulation. In addition to fostering food and income diversification, the traditional farming system reinforces the local food system's resilience to climate change and supports sustainable agrobiodiversity management and agroecological processes.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it focused on the specific role of termite mounds, which are known for their unique properties in natural ecosystems, but have never been studied in agroforestry systems. Eight years after the beginning of the reforestation, the area consisted of a forest, characterized by its specific vegetation and the presence of termite mounds, plantations of pepper, and paddy fields (<i>Oryza sativa</i>). These environments could be discriminated by their specific biological activity and diversity, and soil physical (soil texture, water hydraulic conductivity) and chemical (C, N, P, pH, electrical conductivity) properties. Except for the low tree diversity in pepper plantations, this environment was very similar to the forest, in terms of soil properties and soil fauna diversity, most likely due to the specific climate found in pepper plantations and the utilization of compost for increasing soil fertility. PLS-SEM models showed that the abundance of litter explained more soil chemical properties than tree diversity in the forest. This study also showed that the similar P content in forests compared to cultivated areas, which received organic fertilizers, could be explained by the restitution of P from litter. Finally, we demonstrated that termite mounds can be viewed as hotspots of fertility and biodiversity within the forests, emphasizing their potential use as soil amendment to enhance the fertility of the pepper and rice plantations.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In temperate Europe, light reduction from trees is a significant constraint on crop growth in agroforestry systems, with studies showing mixed effects on crop yield under varying shade. Whereas field experiments provide useful insights, they are often limited in scope, space and time, and cannot fully disentangle interacting factors for all theoretical combinations of, e.g., shade and soil moisture availability. Mathematical modeling offers a flexible approach to study agroforestry systems under a broader range of conditions, thereby allowing for higher spatiotemporal resolution. There is a need for tools that can simulate light conditions more accurately in agroforestry systems, accounting for the complex structure of real-world trees. Here we introduce an intuitive 3D modeling tool designed to simulate light availability at ground level in agroforestry systems, utilizing detailed quantitative structure models obtained from terrestrial LiDAR (Light detection and ranging) scans of real trees. The tool consists of an online application, accessible at https://agroforestry.ilvo.be/agroforlight/, and the R package <i>agroforlight</i>. We showcase its potential in a case study on how tree size and row orientation impact light availability for inter-crops in alley cropping systems. By combining architectural detail with high-speed light computation, the model effectively simulates realistic agroforestry systems at high spatio-temporal resolution.

This study considered five reviews, four meta-analyses, and 131 research articles. Existing meta-analyses and reviews provide valuable insights, while pot-, field-, and landscape-level studies highlight the complexity of agroforestry across different environments. Findings indicate that herbage biomass is primarily reduced by limited light availability and, to a lesser extent, nutrient competition. In arid regions, water scarcity exacerbates tree-crop competition. The effects on nutritive value vary: under shade, crude protein levels increase in grasses but decline in legumes, while fiber content remains stable or decreases. Grass-legume mixtures enhance both yield and quality, benefiting from species interactions. The adoption of optimal grazing management, considering shade presence alongside forage yield and nutritive value, is crucial for improving animal productivity. Most studies highlight key factors for the long-term success of agroforestry, including low tree density, strategic orientation, thinning, pruning, and appropriate stocking rates.

The experiment was conducted under the different natural shade conditions created by a row of tree canopies. Open, partial shade, and full shade conditions for patchouli cultivation were classified based on recorded photosynthetically active radiation. Results revealed that significant enhancements in plant height, (25%), branches per plant (5%), leaves per plant (10%), fresh biomass (19%), dry biomass (13%), and essential oil yield (16%) was recorded compared to open-field cultivation. Furthermore, Partial shade conditions also led to significant improvements in leaf anatomy, including, increased thickness (216.71 ± 7.26 µm), oil gland density (22.71 ± 1.11 mm⁻²), and trichome density (51.29 ± 3.79 mm⁻²), compared to both open and full shade conditions. However, while full shade resulted in larger leaf area (57.55 ± 2.67 Sq.cm), longer petioles (2.5 ± 0.03 cm), and internode lengths (8.5 ± 0.2 cm), it did not translate to higher herb and oil yield compared to open and partial shade conditions.

In response to this challenge, agroforestry emerges as a promising solution to restore tree cover and preserve biodiversity in agricultural landscapes. Despite distributions of millions of trees to farmers through various sustainability initiatives, survival rates of planted trees have been disappointing in cocoa fields. However, many non-planted trees currently exist in cocoa fields, including trees from spontaneous regeneration and remnants from previous forests. Our study aims to explore the origins of tree biodiversity in current Ivorian cocoa fields and identify the key socio-environmental determinants. Across 150 cocoa fields, 9939 trees were botanically identified, allowing estimation of diversity and complementarity levels between planted, spontaneous, and remnant cohorts, linked to socio-environmental variables within a Bayesian modelling framework. Results revealed that remnant and spontaneous trees exhibited much greater diversity than planted trees, with the latter showing important complementarity with the other cohorts. Moreover, the diversity of each tree cohort was influenced by a distinct set of environmental factors such as climate and soil composition, highlighting the need to consider the unique history and location of each cocoa field to support agroforestry development. Effective biodiversity maximisation thus relies on preserving remnant trees, vital sources of propagules for natural regeneration, while carefully selecting spontaneous trees and complementary introducing planted trees. Furthermore, recognizing the farmer’s identity as a key factor shaping observed biodiversity underscores the importance of raising awareness among farmers and offering tree recognition training, particularly for young trees.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-025-01180-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
