Controlled environment agriculture is emerging as a transformative solution, offering sustainable alternatives to these traditional practices. While the economic viability of vertical farms has been demonstrated in various contexts, such conclusions cannot be universally applied without considering specific regional characteristics. This highlights the necessity for detailed case studies. This research evaluates controlled environment agriculture within Qatar, comparing centralized greenhouses to decentralized vertical farms against the backdrop of the region’s distinct environmental challenges. By examining the capital and operational costs, including the critical factor of transportation expenses, the study offers an in-depth economic analysis of both systems. Dynamic analytical models for energy, water, and CO₂ utilization have been developed for greenhouses and vertical farms, to accurately estimate the respective resource usage in each cultivation system. The distribution cost, relevant for the greenhouse scenario, was evaluated using a vehicle routing problem. The findings reveal that greenhouses, with levelized cost of production of $3.19 per kg for tomatoes, offer a more cost-effective solution in Qatar’s specific context than vertical farms, which show a higher cost of $3.77 per kg Although greenhouses currently offer a more cost-effective solution, future studies should incorporate other context-specific factors, including ecological impacts such as water usage, which is particularly critical for regions like Qatar.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By analysing the decomposition of leaf litter and other organic materials, we aim to understand how these processes contribute to nutrient availability and sustainability. This study evaluates the biomass accumulation, nutrient uptake, and cycling dynamics in cashew (<em>Anacardium occidentale</em> L.) in monoculture plantations established on weathered tropical soils over 25 years at Puttur, India. Findings revealed a substantial increase in total above-ground biomass from 0.44 tonnes per hectare (t ha⁻¹) in the first year to 58.78 t ha⁻¹ by year 25. Similarly, root biomass increased significantly, with coarse roots growing from 0.12 t ha⁻¹ to 10.18 t ha⁻¹ and fine roots from 0.14 t ha⁻¹ to 8.19 t ha⁻¹ over the same period. Leaf and litterfall data demonstrated an upward trend in biomass with tree age, contributing to enhanced soil nutrient cycling. Weed biomass showed a declining trend as tree age increased, reflecting the competitive advantage of mature cashew trees. Cashew apple and nut yields also increased markedly, with the apple yield rising from 0.57 t ha⁻¹ to 30.11 t ha⁻¹ and nut yield from 0.08 t ha⁻¹ to 3.72 t ha⁻¹ by year 25. Nutrient analysis of various biomass components indicated significant increases in nitrogen, potassium, phosphorus, calcium, and micronutrients with tree age. The annual nutrient turnover for coarse and fine roots, leaf litter, and cashew apples showed progressive increases, underscoring the critical role of nutrient recycling in maintaining soil fertility and supporting cashew production. The findings highlight the importance of tailored nutrient management strategies to support optimal tree health and yield throughout the lifecycle of trees in the orchard.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100175"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144829945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of the exponential growth in demand for this specialty crop that suffers from limited shelf life, it is imperative to expand raspberry cultivation by employing sustainably-sourced production models. In the current study, we used Cyprus as a case study that is characterised by increased production costs and lack of year-round production despite the fact that the latter is feasible under different production systems and cultivation methods in different altitude-related meso‑climates. Towards that goal, the current study assessed the life cycle environmental impact and life cycle costs of two different cultivation methods - open-field production that took place from May to November 2022 and protected cultivation in high-tunnels, from August 2023 to April 2024, using in both cases the same cultivar (Kwanza®) and plant type. The results indicated that protected cultivation has better environmental performance (3.7 mPt - milli eco-points - per kg of raspberry produced compared to 7.4 mPt for open-field production). Noteworthy, production cost is excessive and substantially higher compared to other countries; open-field production has a life cycle cost of 22.5 €/kg, while protected cultivation achieved a lower life cycle cost, equal to 14.0 €/kg yet still high. From an output perspective, a key observation is the increased yield of raspberries in protected cultivation as well as the enhanced water use efficiency of the crop, due to a reduction of the water footprint by 76 %. It is also important to highlight the increased harvest efficiency of the crop under high tunnel, with 500 g per plant compared to 350 g on open field cultivation. Hence, it is safe to conclude that despite the increased start-up costs and knowledge-intensive practices, the productivity of the crop is increased during the off-season months, that can be sold for a premium. The results highlight the environmental and economic impact of the two cultivation methods and will be useful for producers and crop advisors seeking to expand the raspberry cultivation in climates that resembles south-eastern Europe and are characterised as vulnerable to adverse climate change scenarios.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"11 ","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, circular bioeconomy practices increase agricultural productivity by enhancing crop yields. From a corporate perspective, they optimize resource use, boost profitability, and generate new revenue streams from waste. Socially, these practices improve stakeholder wellbeing and generate employment opportunities. Environmentally, they support natural capital regeneration, reduce ecological footprints, and promote the sustainable use of resources.

Despite extensive studies on the impacts of coffee farm management on biodiversity, the trends in research on this issue over the last two decades remain unclear. Therefore, this work was initiated with the aim of conducting a systematic evidence map study concerning the impacts of coffee production on biodiversity throughout tropical coffee-producing countries. After conducting a search of the literature in peer-reviewed journal databases and gray literature, we screened the identified papers using machine learning-related software, identifying a total of 292 studies for inclusion in the systematic map database and synthesis. We found that there was a trend for an increase in the number of publications examining the relationship between coffee cultivation and tropical biodiversity, with the majority of studies being conducted in Latin America. Among coffee management interventions, studies on the effects of land-use gradients driven by coffee cultivation and shade management on invertebrate biodiversity were identified as dominant topics. Meanwhile, there were fewer studies measuring the impacts of water management on tropical biodiversity.
