This study examined how the agroforestry tree Gliricidia sepium intercropped with soybean, groundnuts, or maize affects crop nutrient compositions. The study was conducted in five Zambian chiefdoms for three crop-growing seasons (2019–2022) on 13 farmer-led demonstration trial sites. Seven treatments were tested that included maize, soybean, and groundnut plots with and without Gliricidia interventions. Grain samples were analyzed for crop nutrient contents using standard laboratory methods. Results showed that the treatments significantly (P < 0.05) improved maize nutritional properties except for crude fiber, total carbohydrate, and metabolizable energy. G. sepium intercropping with maize and soybean decreased the antinutritional contents and displayed better functional qualities. All elemental mineral components (except potassium, calcium, and sodium) were higher in the Gliricidia + maize intercrop than in the control treatment. The Gliricidia+soybean intercrop had lower mean mineral concentrations than the control (soybean only) except for Mg, Cu, and Zn. The Giliricidia+groundnut intercrop significantly increased groundnut mineral components except for Nitrogen, Phosphorus, Potassium, and Iron. It can be concluded that G. sepium intercropped with maize, soybean, and groundnuts significantly improved the crops’ nutritional quality.KEYWORDS: AgroforestryZambiaGliricidia sepiumlegumesnutritional qualitymineral AcknowledgmentsThe authors acknowledge the financial support from NORAD/Ministry of Foreign Affairs, Norway, and the support of all farmers participating in the study.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data supporting this study’s findings are openly available at https://doi.org/10.25502/0fa9-dm27/d.Supplemental dataSupplemental data for this article can be accessed online at https://doi.org/10.1080/21683565.2023.2254711.Additional informationFundingThis project has received funding from the Norwegian Agency for Development Cooperation (Norad) under Saksnr: 1800165-18.","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136072334","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 countries with large public education systems, school and university canteen services can play a significant role by virtue of their enormous centralized purchasing power. In this study, we investigate the potential and feasibility of implementing an enduring transformation to a sustainable food procurement model in public higher education institutions based on agroecological principles for the case of Spain. To address our research questions, we employed participatory workshops and a questionnaire survey (1,058 respondents) to analyze perceptions and priorities around sustainable food practices on campus of the university community across three Spanish public universities. Workshop participants proposed and prioritized interventions aimed at improving the sustainability of on-campus food services. Some recommendations for action for policy makers are detailed in the Discussion section, as key actors in this process. Pathways toward a future transition to more sustainable practices included the importance of food services to the university community, the high level of understanding of food system impacts and demand for change from consumers on university campuses, the universities’ commitment to the UN Sustainable Development Goals and the potential of university networks as a powerful agent of social change and social innovation.","PeriodicalId":48958,"journal":{"name":"Agroecology and Sustainable Food Systems","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43372763","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}

Sociodemographic factors such as market accessibility and household assets could be shaping the structure of these networks and impacting diversity, however formal evidence is scarce. Through surveys in nine rural communities in the Cofre de Perote highland region in Mexico, we modeled seed exchange networks for native maize and conducted a social network analysis followed by statistical modeling. Results show that access to urban centers is negatively related to the robustness of community networks. Within communities, households with bigger plots, more time producing, sufficient maize for self-consumption, and fewer members were able to save seeds for the next cropping season and were more likely to donate seeds. Additionally, households that exchanged more produced more maize morphotypes. We conclude that the maize seed networks under study are serving as seed reservoirs for families in case of scarcity, thus contributing to food security. They are also important for in situ agrobiodiversity conservation of six maize morphotypes. However, it is necessary to promote seed exchanges between households of communities with more access to urban centers, to strengthen networks, and preserve their maize diversity and seed scarcity-dampening function.

This article is based on a collective, reflexive and comparative analysis of eight research projects dealing with agroecological transitions at the scale of farming systems and agrifood systems. Each project brought together a diversity of actors having different visions of ecologization. The aim of this article is to describe how and with what benefits this diversity of visions was addressed in the projects. We show that taking into account the diversity of visions is necessary for understanding agroecological transitions, and that beyond this, sharing this diversity among the concerned actors is necessary for accompanying them in an inclusive way and, under certain conditions, enrich transition pathways. We also show the need to adopt analytical approaches to characterize the visions along with participatory action-research approaches allowing to share them and support transitions.

We argue that a combination of these two approaches makes polyculture design tools more robust. We assessed quantity, quality, and complementarity of information from multiple sources for designing diversified cropping systems with vegetables and spice crops for cold temperate climate. Trait and observational data were integrated from: (i) two grower-oriented and one academic crop database, (ii) a survey of farmers practicing community-supported agriculture, and (iii) a systematic literature review on the use of spice crops in vegetable farming. Survey results reveal that the farmers were capable of achieving medium to good levels of their main goals, but failed to reach desired multifunctionality with their polycultures, which can be potentially improved with computational tools. None of the analyzed data sources provided a comprehensive dataset for all target crops and functional traits. However, source combination allowed for design from known crop companions (farmers survey and grower-oriented databases), to addressing specific pest problems (literature review), and increasing functional complementarity and facilitation by trait matching (academic and grower-oriented trait databases). Integrating information from different sources increased the number of crop combination options but also planning and management complexity.

Insect herbivores cause significant damage for maize production, and as a result, global pesticide use has increased over the last 20 years causing severe environmental degradation and negative impacts on human health. Today, there is a trend toward including more sustainable management practices that are less harmful to biodiversity and human health. One such a practice is the use of natural enemies to regulate pest populations using conservation biocontrol or introduction of biocontrol agents. These practices have been in place for several decades in different cultivation systems and regions throughout the world, however; information about the effects of more sustainable management practices on maize production is scarce. We conducted an expert assessment to evaluate whether there are any general trends or consensus about the importance of biocontrol for maize production globally. We compiled information from 70 experts from 28 different countries using an online survey. Of those surveyed, 91% of experts agreed that biocontrol was important for maize production regardless the type of maize they study, the final harvest destination or crop use, or management regime. Using the information obtained, we identify several opportunities for engaging with farmers in order to use biocontrol as a tool toward agricultural sustainability.
