Before human intervention, the natural resistome existed in a relatively balanced state, mainly regulated by microbial interactions and environmental factors. However, the continuous use of antimicrobials and other novel entities (chemicals or biological substances) in agricultural production and clinical settings has resulted in a huge release of residual antimicrobials into the environment. This may lead to a decrease in microbial diversity and an increase in selection pressure. The outcome is the alteration of resistome with mobile and clinically relevant antibiotic resistance genes (ARGs), posing a significant risk to human health. In the agricultural sector, the emergence of AMR is a result of multiple mechanisms. It involves intricate interactions between human activities, environmental factors and microbial processes. Direct exposure to antibiotic-resistant bacteria and ARGs in agricultural produce particularly raw eaten vegetables, salad, herbs and fruits may facilitate the spread of resistance between humans and the environment. This review aims to provide a comprehensive overview of antibiotic resistance in fresh produce microbiomes. It focuses on the impact of agricultural practices on the resistome and risks associated with antibiotic resistance to humans and the environment.

While growing has boomed, profitable agronomic practices lag behind in the infant industry. Growers are specifically interested in weed and pest management strategies that do not impact yield or quality, as there are few herbicide and pesticide options for hemp, and they want agronomic practices to be sustainable or regenerative. Our research assesses the utility of companion cropping to address these needs. Companion cropping is a cultural management tactic within farming systems in which a secondary crop is planted with the main crop, offering an array of potential benefits and ecosystem services. Some of the possible benefits of companion cropping within hemp systems include weed control, additional food sources and habitat for beneficial insects, pest deterrence, increased crop productivity, soil health, and environmental resilience against stresses. To determine which companion crops are most suitable within cannabidiol (CBD) hemp production, we have analyzed the effects of intercropping five companions (basil, dill, cilantro, sage, and marigold, against a blank control) on: (i) companion plant yield and profit, (ii) weed competition, (iii) insect diversity, (iv) hemp biomass yield, and (vi) cannabinoid content. Results show that companion crops differentially and significantly impact weed cover and insect diversity, but do not significantly impact yield or cannabinoid content, with marigold and basil being the most promising. This means that growers can choose companion crops that fit their farm and equipment best without having to worry about a negative impact to quality and yield. Future studies will focus on implementation of companion cropping through on farm trials, an exciting and necessary next step to a sustainable future for cannabis production.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined how taxonomic diversity, structural diversity (CV-DBH, CV-height) and environmental factors contribute to AGB and aboveground carbon (AGC) stocks.

Elevation negatively influenced AGB at both sites, while NDVI and EVI2 were positively correlated with AGC in Kongoussi but not in Cassou.
