To know the current status, challenges, and opportunities of agroforestry in rice-based systems, this study was conducted in Northern Bangladesh. Data were collected from 120 farmers through face-to-face interviews using a pre-tested structured questionnaire, and in addition, several focus group discussions (FGDs) and key informant interviews (KIIs) were conducted. Agroforestry systems observed include homestead agroforestry, integrated cropland agroforestry, windbreak plantations, fodder bank agroforestry, aquaforestry, and timber-fuelwood systems. Among these, homestead agroforestry emerged as the most prevalent (90.8% adoption), providing diverse income streams and nutritional benefits through fruits, vegetables, and timber. Rice-tree combinations, such as rice with litchi <i>(Litchi chinensis</i>), mango (<i>Mangifera indica</i>), eucalyptus <i>(Eucalyptus camaldulensis)</i>, mahogany <i>(Swietenia macrophylla)</i>, and betel nut <i>(Areca catechu)</i>/tal <i>(Borassus flabellifer)</i>, offer unique socio-economic and ecological benefits as perceived by the respondents. High initial costs, inadequate knowledge and skills, land ownership patterns, and market access are some of the major challenges that hamper extensive adoption. However, agroforestry in rice-based mixed farming has great potential to improve net primary value (NPV), year-round income, climate resilience, and soil health, among many others. Training, subsidized inputs, market access, and credit facilities are some of the major supports required to accelerate the adoption of agroforestry, as perceived by the respondents, offering important guidelines for researchers and policymakers.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998604","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}

Twenty-four farms were located along an altitudinal gradient from 150 to 1260 masl. The study reveals that, along the altitudinal gradient, neither altitude nor management system significantly affected the soil’s physical and chemical properties. However, significant differences (95% CI) in pH, phosphorus (P), potassium (K), and cation exchange capacity (CEC) were identified at mid-altitudes, associated with the presence of CaCO₃. These findings suggest edaphic stability in Amazonian pasture systems despite altitudinal and management variations, while highlighting the key role of CaCO₃ in soil fertility under these conditions. SPS exhibited high tree diversity, with more than 20 families and 40 species identified − 58% of which belonged to Simaroubaceae, Asteraceae, Fabaceae, and Malvaceae. The greatest tree diversity was concentrated at 170 m altitude, indicating greater ecological stability and resilience at lower elevations. Additionally, SPS showed a strong capacity to regulate the microclimate by lowering temperature and solar radiation while increasing relative humidity, in contrast to MCS.

This study investigated how farmers’ practices, particularly cocoa stand management, influence long-term cocoa yields, considering the production area’s history and current management. Cocoa plantations aged from 7 to over 60 years were selected in two areas: an old cocoa production area (Bakoa) and a cocoa pioneer front in the forested land (Talba) in Cameroon’s Centre region. Measurements included cocoa and associated tree diameters, shade tree cover and accessible cocoa yield. We also identified architectural types of cocoa trees representing various development stages. Results showed no effect of plantation age on associated tree parameters at either site. In Talba, cocoa tree density and accessible yield decreased with plantation age. This decline was associated with an increase in senescent cocoa trees and few regenerated multi-stem trees over time. This indicates poor rejuvenation of existing plantations in Talba, where forest reserves are available to create new ones. Conversely, in Bakoa, an area with no available forest reserves, rejuvenation of existing plantations, evidenced by the increasing density of multi-stem cocoa trees and new seedlings over time, was associated with stable yields in the long term. Providing farmers with training and incentives to rejuvenate old cocoa stands should be part of an overall strategy to increase production, improve farmers' incomes, protect forests and comply with the commercial rules of consumer countries.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-025-01285-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144929425","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}

Agroforestry, particularly homegardens, offers a viable land-use strategy to combat both challenges. However, the direct effects of elevation, farm size, and wealth level on carbon stock in these systems, as well as their indirect effects mediated by species diversity and stand structures, remain poorly understood. In this study, we hypothesized that: (1) perennial plant species diversity and stand structures (such as basal area and stem density) directly contribute to biomass C stock in the homegarden AF systems of the central highlands of Ethiopia; (2) elevation, farm size, and wealth levels primarily affect biomass C stock indirectly, with weaker direct effects; and (3) stand structures have a more significant role than perennial plant species diversity in mediating the response of biomass C stock to these factors. We collected vegetation data from 252 sample farms, randomly selected from three purposively chosen kebeles. Structural equation modeling (SEM) was used to analyze the direct and indirect relationships among elevation, socioeconomic factors, species diversity, stand structure, and aboveground biomass C stock. The results indicated that basal area and stem density have the strongest direct positive effects on biomass C stock, highlighting the critical role of stand structure in determining biomass C stock. Elevation influenced biomass C stock directly, but this effect was largely mediated through stand structures (stem density and basal area), supporting our hypothesis that elevation affects biomass C stock indirectly. Farm size also had a significant direct effect on biomass C stock, with indirect effects through stem density and basal area; however, it did not impact biomass C stock via perennial plant species diversity. Wealth levels influenced biomass C stock both directly and indirectly, with indirect effects mediated by perennial plant species diversity, stem density, and basal area. These findings highlight that stand structural attributes, particularly basal area and tree density, are the most influential determinants of biomass C stock in Ethiopian homegarden AF systems. Elevation and socioeconomic variables mainly affect biomass C stock indirectly, emphasizing the importance of maintaining stand structures and enhancing species diversity to optimize carbon sequestration and ecosystem services in agroforestry landscapes.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144923289","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}
