The complexity of these relationships can be seen in both above- and belowground ecosystems and understanding these intricate relationships between biodiversity and ecosystem functioning (BEF) is critical to ecological research, especially in the context of rapidly changing global environments. This review synthesizes contemporary research and fundamental insights into BEF linkages, with a particular emphasis on the function of plant-microbial biotic interactions in shaping aboveground biodiversity and their cascading effects on ecosystem processes. One of the most significant developments is the discovery that microbial communities responsible for a variety of soil functions are inextricably linked to plant communities and ecosystem processes. However, BEF studies rarely explore the relationships between above- and belowground biodiversity components, as well as how global change affects them. In light of this, we propose emerging paths for future study, emphasizing the necessity of global-scale networks and collaborative efforts to address difficult ecological challenges. Addressing these crucial knowledge gaps might help to improve our understanding of the interplay between biodiversity, biotic interactions and ecosystem functions, thereby improving primary productivity as well as ecosystem resilience and sustainability in the face of projected global change.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.12119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002553","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}

However, their limited storability challenges producers and exporters, resulting in significant postharvest losses. Traditional preservation methods like cold storage, controlled atmosphere storage and packaging techniques have been employed to prolong shelf life, but they have their constraints. Biotechnological interventions, notably genetic engineering, offer promising avenues to address these limitations. Genetic modifications target physiological processes such as ripening and ethylene production, enhancing resistance to postharvest diseases and improving nutritional profiles. For instance, genetically modified tomatoes with prolonged shelf life and reduced susceptibility to fungal infections showcase the potential of genetic engineering. Similarly, genetic modification has been successfully applied to various horticultural crops like apples, bananas and mushrooms, resulting in decreased browning and heightened disease resistance. Emerging technologies such as modified atmosphere packaging, edible coatings and nanoparticle treatments further augment efforts to extend shelf life. Despite their benefits, the debate surrounding genetically modified fruits and vegetables persists due to concerns regarding environmental impact, health implications and ethical considerations. This review offers insights into current practices and research endeavours aimed at enhancing the shelf life of horticultural crops through both traditional and biotechnological means, shedding light on opportunities and hurdles in this domain. Future directions include intensifying basic research to unravel molecular processes in harvested tissues, prioritising investigations that directly benefit consumers and developing sustainable and cost-effective approaches for emerging technologies like modified atmosphere packaging, edible coatings and postharvest treatments.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.12121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141967879","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}

At the Kabwe site, the effect of organic amendment on soil fauna abundance was minimal, although significantly higher crop yields were observed in soils with organic amendment.

The maturity index, plant-parasitic index, channel index and structure index were greater for IWG sites. The enrichment index was greater for annual wheat sites due to the dominance of bacterivores and enrichment indicators (c-p 1 nematodes). The nematode community structure (weighted faunal profile analysis) indicates IWG sites as being a generally undisturbed system with efficient nutrient cycling and balanced distribution of feeding types, as well as higher metabolic footprint values for root feeders (including plant-parasitic nematodes) and fungivores. Annual wheat sites, on the other hand, held indicators of a disturbed system with increased occurrence of opportunistic species and a more bacterial driven pathway. The topsoil had an increased occurrence of structure indicators in both cropping systems.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>IWG creates favourable conditions for a diverse food web, including improved nutrient cycling and a heterogeneous resource environment, regardless of climatic conditions, establishing it as a stable and resilient agricultural management system.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.12112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141624234","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}
