While most studies have investigated the performance of understory crops, more information is needed about the performance of trees in agroforestry systems. In the last decades, the forest industry in the Southeast has produced high-yielding loblolly pine varieties that can be propagated by cloning. We evaluated the performance of two forest industry-rated loblolly pine clones (<i>Pinus taeda</i> L.) that we planted in an agroforestry and a plantation setting at a northern Alabama site. Specifically, we assessed and compared the survival and growth of two genetically improved pine clones: clone 1 (CF Q3802-43) and clone 2 (CF L3519-41). Clone 1 had a significantly higher overall survival rate than clone 2 (86% vs. 83%). However, clone 2 demonstrated a superior performance growth compared to clone 1. Tree basal area, live crown ratio, height and total tree volume inside-bark of clone 2 averaged 0.027 m<sup>2</sup>, 70%, 10.7 m and 0.11 m<sup>3</sup>, respectively, and all were significantly higher than those of clone 1 (0.024 m<sup>2</sup>, 63%, 9.8 m, and 0.09 m<sup>3</sup>). Therefore, clone 1 is preferred over clone 2 for our region and in similar site conditions if survival is considered a selection criterion and clone 2 is preferred from the wood production viewpoint. However, it will be more advantageous to use clone 2 overall since its higher average tree volume (0.11 m<sup>3</sup> vs. 0.09 m<sup>3</sup> of clone 1) can easily offset the lower survival rate.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2449 - 2461"},"PeriodicalIF":2.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884531","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}

Whereas this has led to multiple cocoa agroforestry investments by NGOs, governments, and cocoa and chocolate companies in West and Central Africa, a notable gap exists in the literature on how these interventions respond to the needs of cocoa farmers who are typically framed as the primary target of equity in cocoa sustainability discussions. This paper contributes to bridging this gap by analyzing equity in implementing various cocoa agroforestry projects by different actors in Ghana’s Juabeso-Bia Landscape (JBL). I find that the ongoing cocoa agroforestry initiatives may be broadly characterized as renovative or additive in terms of how they (re)shape the various components on cocoa farms. Yet, they are all designed to primarily enhance cocoa productivity even when seasonal food insecurity is one of the most pressing challenges among cocoa farmers in the JBL. The persistent neglect of food in cocoa production risks leaving poverty and hunger in cocoa households unaddressed. Additionally, it increases cocoa households' predisposition to forest conversion, making current forms of cocoa agroforestry an indirect driver of deforestation in the landscape. To transform the current situation, policymakers and scholars must reflexively integrate household food security in designing cocoa agroforestry, prioritizing farmers’ involvement in dynamic agroforestry technologies that contribute directly to local food access over time. This contrasts the current policy and practice of cocoa agroforestry, focused on maintaining a prescribed number of shade trees on new or existing cocoa farms but highly likely to engender significantly greater inequity in the cocoa sector.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2463 - 2481"},"PeriodicalIF":2.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-024-01041-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884671","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}

The process of digitalization offers significant opportunities to enhance sustainability, but it remains crucial to foster a human-centric, fair, and sustainable approach. In the context of the DigitAF Horizon Europe project, we present the results of a multi-stakeholder questionnaire aimed at understanding the perceptions of stakeholders regarding agroforestry and digitalization, as well as the needs of these stakeholders for a successful implementation of this agricultural practice. In the questionnaire, there was a specific focus on the need for and the conditions for the use of digital tools and models, such as generalized digital tools, applications and mapping, climate and weather forecasting and recording, farm management and decision support, and agroforestry and environmental tools. The purpose of this survey was to provide insights to inform agroforestry actors and to foster collaborative initiatives that enhance the potential of digital tools to support the design, implementation, and maintenance of effective and sustainable agroforestry in the European context. Our questionnaire was completed by stakeholders from seven European countries, including farmers, academics, policy actors, farm advisors, and actors in the value chain with an interest in agroforestry. Stakeholders from six living labs, representing Czechia, Finland, Germany, Italy, the Netherlands, and the UK, were involved in the appraisal, along with a multi-stakeholder group from Belgium. Respondents used data and digital tools for various purposes in farming systems and were interested in their potential to improve agroforestry including animal, tree, and crop performance, management guidance, system design, and tree species selection. Our survey revealed that the perceived usefulness of digital tools for agroforestry was substantially higher than stakeholders' awareness of existing tools, indicating a need for better promotion and development of user-friendly, accessible solutions. Additionally, significant obstacles to agroforestry adoption, such as large up-front investments, administrative burdens, and fear of reduced CAP support, were identified, emphasizing the necessity for targeted support and policy improvements. Moving forward, efforts should focus on developing targeted solutions to promote agroforestry according to stakeholder perception, and user-friendly digital tools tailored to the needs and preferences expressed by stakeholders, while also increasing knowledge sharing and capacity building among practitioners and researchers.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2499 - 2515"},"PeriodicalIF":2.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-024-01047-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884672","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}

Our current food system continues to respond to contemporary forces with a call for sustainable transformations in the face of increased pressure and competition over resources, severe consequences of climatic change, widespread degradation of land and water resources, and the accelerating loss of biodiversity. Both agroforestry and agroecology have evolved as approaches to agricultural management that focus on the application of ecological principles to achieve sustainable agriculture. Agroecological principles are designed to engage with the entire agrifood system, for instance identifying broad participation and involving a diversity of actors and knowledge systems. Agroecological approaches to production have significant historical and contemporary links to agroforestry approaches, but not all agroecology involves trees and not all agroforestry is in line with agroecological principles. Drawing on (1) a literature review, (2) case studies on the agroforestry and agroecology nexus presented at the 5th World Congress on Agroforestry (WCA), and (3) audience responses to statements presented at the Congress, we explore the two main ways that agroforestry and agroecology come together: agroforestry that encompasses agroecological principles and agroecological transitions that involve trees. We review the status of agroecology, the functions specific to agroforestry that can enhance the achievement of agroecological outcomes, the tensions between simple agroforestry systems and agroecology, and the larger potential of multidimensional sustainability of agroforestry with the inclusion of agroecological principles. We also present the level of agreement on four key statements about the agroforestry-agroecology nexus enumerated at the WCA. It is clear that some features of agroforestry operationalize agroecological principles that aim to transition away from monocultures and the use of environmentally disruptive agrochemicals, and toward strengthening biodiversity and resilience. Yet, much remains to be done to enhance agroecological principles more fully in framing agroforestry practices and to incorporate trees within agroecological practices. Pathways to strengthen the nexus of agroforestry and agroecology are proposed, which focus on the role of trees in multifunctionality and resilience and using agroecological principles related to knowledge sharing and equity to enrich agroforestry practices.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2369 - 2383"},"PeriodicalIF":2.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-024-01014-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884665","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}

Younger trees generated a more heterogeneous system with more pronounced zones, where the middle alley resembles the control without trees in the studied variables.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2071 - 2085"},"PeriodicalIF":2.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865289","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}

Thousands of hectares have been replaced by pasture monoculture with negative consequences for the biodiversity. Silvopastoral systems (SPS) have been promoted in the region as an alternative to improve tree cover, biodiversity and productivity of cattle farms. To analyze the impact of SPS on plant and bird diversity, 22 plots with three silvopastoral arrangements (tree alleys: TA, scattered trees in pastures: STP, intensive silvopastoral systems: iSPS) and pasture monocultures (PM) were sampled using 20 × 50 m quadrats for vegetation and 50 m radius fixed points for birds. A total of 556 individuals of 26 families and 60 plant species were found. TA and STP had significantly higher abundance and richness of vegetation than PM. For bird fauna 2209 individuals belonging to 18 orders, 42 families and 149 species were present. Bird diversity and abundance were significantly higher in TA than PM. The diversity and abundance of plants, as well as vegetation structure had a positive and significant effect on the abundance and richness of birds, and on the richness of frugivorous, insectivorous, and omnivorous birds, and the richness of species with preferences for different habitats. Plant diversity and structure complexity is key to improve diversity of birds, frugivorous and insectivorous species and therefore should be considered when selecting plant species to be introduced in the cattle systems.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"98 7","pages":"2253 - 2266"},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770581","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}
