A total of 21 plant species were recorded, and the carbon stored in live aboveground biomass was estimated. The results showed that coffee-based AFS has a high potential for carbon storage, and species diversity is related to the structural parameters and diversity of each sampling site. The implementation of coffee-based AFS is an effective strategy for the conservation of native flora and climate change mitigation in the area.KEYWORDS: Climate changegreenhouse effecttree diversitycoffee-based AFSproduction systems Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135888274","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}

{"title":"The conceptual babel of agroecologies is related to their diverse origins and objectives","authors":"Francisco Javier Espinosa-García, Erick de la Barrera, Alba González Jácome","doi":"10.1080/21683565.2023.2270938","DOIUrl":"https://doi.org/10.1080/21683565.2023.2270938","url":null,"abstract":"ABSTRACTThe term agroecology has undergone broad diversification since it was first conceived as the study of the ecology of agricultural systems. In addition to the “tripartite” definition, which includes science, practice, and social movement, political and “emancipatory” agroecologies, among others, are included. There is no consensus on the meaning of “agroecology” and “agroecological,” nor the objectives and uses associated with those concepts. Thus, despite the concept of “agroecology” not being consolidated nor unisemic, its meaning and application continue to diversify according to the interests and perspectives of the users. That diversification encompasses different ways of looking at agriculture’s role in human societies and the environment in which they are based and function. Agroecology, too, has been seen as an activity whose objectives include issues as diverse as mythical, ceremonial, dogmatic, political, or religious. Moreover, this unrestricted diversification also devalues and trivializes the term and hinders the mutual understanding among academics, practitioners, promoters, decision-makers, the public, and government agencies. We begin a series of reflections on the various agroecologies in Mexico that we hope will promote the formation of clear, well-defined, and documented concepts to contribute to synergies among agroecologies and the advancement of their objectives.KEYWORDS: Conceptual confusionconceptual diversificationsustainable agriculturescientific agroecologytechnological agroecology AcknowledgmentsThis work was supported by the Instituto de Investigaciones en Ecosistemas y Sustentabilidad-UNAM under Grants IIESPO-FJEG; IIESPO-EBM.Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1.

However, at a policy level, alternative conceptualizations of agroecology have emerged that emphasize on-farm efficiency gains but lack broader objectives of agroecosystem and food system transformation. This phenomenological inquiry explores the agroecological narrative among Scottish farmers and considers its impacts on agroecosystem and food system change. Interviews were conducted across 15 farms in Scotland (20 participants) following the trans positional cognition approach (TPCA). Actualizations of agroecology were found to be value-driven approaches to developing individualized, lower-input farming systems. All farms were attempting to influence agroecosystem change through the application of ecological principles, and most (11/15) were contributing to food system change directly through involvement in alternative food networks. Smaller-scale farmers appear to deliver the most authentic actualizations of transformative agroecology but emphasized more strongly their financial challenges. A key recommendation for policymakers is to strengthen the support mechanisms available for small-scale ecological agriculture.","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113080","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}

AER and AEA integration allowed secure data storage and real-time automated visualization and statistical analyses without programming. At no field station did legume intercropping or biological pest control increase cassava yields. The Chambezi field station had the highest yields even under untreated control conditions and only here, soil fertility amendments further increased root weights. Intercropping with cowpea legumes, alone or in combination with other practices, had no significant effect on cassava plant size or survival at the Mumbaka and Vianzi field sites and even negatively affected one or both parameters. Organic pest control had no effect on any target variable, except for plant size at Chambezi. Therefore, labor-intensive and expensive pest control practices may not be worth the investment at least when virus-resistant cassava varieties like Kiroba are used.","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135350624","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}

Four key indicators of farmers’ food security – enset stock, land sharing, agricultural biodiversity, and fodder production – were assessed before and after the project implementation. The findings reveal that the agroecological transition initiated by the project positively impacted all indicators, with longer-term beneficiaries experiencing more significant improvements. The transition resulted in breaking the vicious circle of food insecurity and in establishing a virtuous circle of improved livelihoods and resilience through enhanced productivity, reintroduction of livestock, and the production and marketing of fodder into local markets. The study also highlights the crucial role of traditional indigenous organizations, in identifying context-specific needs and in creating and sharing knowledge for successful agroecological transitions. Millions of smallholder farmers in Ethiopia are trapped in a vicious circle of food insecurity and vulnerability due to soil degradation, high population density, and depletion of natural resources. This research serves as a compelling call to prioritize and invest in agroecology as a key solution to sustainably intensify smallholder agriculture, conserve natural resources, protect biodiversity, and improve the livelihoods of vulnerable farmers in similar contexts.","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739705","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}

Analysis was done using PCA and social network analysis from 167 surveys. Results show that grassroots initiatives impact 18 indigenous groups in the center and south of Mexico, and focus on eco-friendly production, social justice, popular education, and food markets. Initiatives started because of three tipping points that responded to neoliberal policies, relocating local food and massifying agroecology.
