ABSTRACT Food losses are a critical concern for economic, social, and environmental sustainability within logistics systems. This paper quantifies food losses in India's pulses trade, examining specific cases and identifying causes and stages of losses in the international food supply chain. Focusing on sustainable development goals, it offers insights into food losses in internationally traded cargo (pulses), which rank second in the FAO-Food Loss Index and are India's second-largest imported food product. Using a descriptive research methodology, the study unravels the complexities of food losses in India's pulse supply chain. Primary data were collected via questionnaires from 130 importing firms and supply chain professionals, supplemented by secondary sources. Purposive sampling guided data collection from April 2023 to May 2024, involving virtual and physical stakeholder interactions. The comprehensive analysis provides strategies to mitigate food losses, laying the groundwork for improvements in India and other developing countries.

Waste, the real villain: a comprehensive analysis and prospective perspective on food loss and waste in China

IntroductionOne of the best ways to ensure food security is to reduce Food Loss and Waste (FLW). However, China still confronts numerous obstacles in food loss and waste study because of the intricate industrial chain, the wide range of accounting standards, and a lack of data, among other reasons.MethodsUsing the literature analysis method, 119 literatures were collected and analyzed to examine the current status of FLW in China at various stages after food production and throughout the life cycle from the perspectives of time series and research areas.ResultsThe study indicates that the rates of FLW in China have been higher than 20% in recent years and are still increasing. Among them, the highest FLW rates were found in the harvesting stage (3–6%), storage stage (8–10%) and consumption stage (10–17%). In addition, FLW results in a huge waste of resource endowments.DiscussionThe environment and resources are profoundly affected by these substantial food losses and wastes, leading to unnecessary depletion of resources. As China’s focus on food loss and waste intensifies, an increasing number of academics are expected to delve into this area, exploring dimensions such as ecological footprint assessment, innovative uses for food waste, and gathering primary data.

Minimizing postharvest food losses: a vital strategy to alleviate food insecurity and malnutrition in developing nations: a review

Abstract As global food production encounters escalating challenges, postharvest losses (PHLs) emerge as a critical yet often overlooked issue. Despite considerable progress in food production, PHLs remain a significant concern, accounting for an average of 14% of food production in 2021. Against the backdrop of 811 million people facing food insecurity and the triple burden of malnutrition, it becomes increasingly evident that reducing food losses offers a sustainable solution to enhancing global food and nutritional security, particularly in developing countries. This review aims to underscore the significance of PHLs, their impact on global food security, and the current PHL scenario in developing nations. Despite the abundance of innovative technologies developed by researchers, accessibility to these technologies remains limited for farmers in many countries. The ongoing struggle and dire circumstances surrounding proper food handling in developing nations necessitate immediate action. Research efforts must focus on assessing the regional applicability, costs, and economic returns of existing technologies for mitigating PHLs. In addition to capital investments, the long-term sustainability of reducing PHLs hinges on ensuring the effective use of these technologies through education and training. Graphical Abstract

Techno-Economic Analysis of BAU-STR Dryer for Rice Drying: An Approach to Accelerate Adoption

Postharvest food loss and waste offset worldwide agricultural productivity and food security. Insufficient drying and storage are the prominent drivers of food loss and waste in underdeveloped countries. Mechanical grain drying systems have distinct benefits over sun drying but are inaccessible to underserved communities due to high capital costs and energy demand. This study evaluated the techno-economic and financial performance of a half-ton-capacity BAU-STR dryer. The moisture extraction rate, drying rate, drying efficiency, and energy consumption were used as technical performance indicators. In contrast, the net present value (NPV), internal rate of return (IRR), benefit–cost ratio (BCR), and payback period were considered economic performance indicators. The technical performance analysis results revealed that the moisture content of rice was reduced from 19.5% to 13.5 ± 0.15% in 4.0 h with an average drying rate of 1.5%/h and a drying efficiency of 75.1%. The financial performance analysis resulted in a drying cost, NPV, IRR, BCR, and PBP of USD 0.96 per 100 kg of grain, USD 3018, 135%, 3.0, and 0.73 yr., respectively, when the annual use was 240 h. If the yearly use of the dryer increased from 240 to 720 h, a higher NPV, IRR, and BCR, as well as a lower payback period and drying cost, could be achieved. Adopting a BAU-STR dryer for drying grain (rice and corn) among underserved communities could play a key role in postharvest food loss and waste.

Smart Agriculture Crop Management Warehouse

In a developing country like India, agriculture is one the most important sectors in terms of financial gain and providing healthy foods to survive. Agriculture is the primary occupation in our country for ages and most of the population depend on it. Now-a-days farmers are facing huge losses due to some storage requirements, while storing agricultural products. A Farmer should have knowledge about the condition of their agricultural crops. Farmers are keeping their agricultural crops in warehouses to increase the lifetime of food grains. Food plays a significant vital role in life, once it involves food security that is littered with each food loss and food wastages. Reports suggests that almost fifty proportion of the food made world-wide doesn't even reach the individuals as they're wasted throughout harvest, transportation, or storage. One in all the point that threats to the farmers is that the loss throughout storage of crops in granaries and warehouses. If crop losses are reduced, it'll mechanically increase the number of food accessibility. To solve this problem one solution is that this project includes smart warehouse management and monitoring farming field, which includes temperature maintenance, humidity maintenance, fire alarms, stock measurement, Pest control. To assist and help the farmers who protects the crops by storing in warehouse, a fully automated enabled observation system is planned to be deployed in remote areas wherever the accessibility is incredibly minimum for farmers with smart storage facilities to scale back food losses and increase food safety. Keywords: Agricultural crops monitoring and controlling, fully automated technology, Sensors, Warehouse management system.

Mapping the Sustainability of Waste-to-Energy Processes for Food Loss and Waste in Mexico—Part 2: Environmental and Economic Analysis

Mexico generated 8.9 million tons of food loss and waste (FLW) in the year 2022, which was primarily managed through linear economy schemes where final disposal sites are predominant, leading to significant contributions to climate change and economic losses. This study, as a continuation of a prior work (Part 1), aims to evaluate the economic and environmental feasibility of implementing waste-to-energy anaerobic digestion (WtE-AD) plants for FLW management across Mexico, identifying the key factors that influence the competitiveness of these systems compared to conventional waste management practices. Using the outcomes of an energy feasibility analysis (Part 1), alongside life cycle assessment (LCA), geographic information systems, and cost engineering, this research analyzes the eco-efficiency and viability of WtE-AD for FLW valorization throughout the Mexican territory. The results indicate that, with a conventional waste management fee of USD 35.4 t−1, only the largest WtE-AD plant in the State of Mexico (treatment capacity of 2536.8 t FLW d−1) achieved a positive net present value (NPV) of USD 70.1 million, while all the other plants remained economically unviable. Conversely, under an optimistic scenario with a fee of USD 139 t−1, plants processing over 50 t FLW d−1 achieved profitability, with the largest plant reaching an NPV of USD 1.15 billion. The environmental assessment showed that larger plants effectively act as carbon sinks, with the largest plant reducing emissions by up to −89.8 kg CO₂ eq t−1 of FLW. These findings emphasize the need for appropriate waste management fees and governmental incentives to ensure the economic viability of WtE-AD plants. This study provides valuable insights for policymakers, highlighting the potential of WtE-AD technologies to contribute to Mexico’s energy transition and the shift toward a circular economy.

Detecting water-soaked disorder and reddish-pulp disorder in peach fruit using bio-speckle

This study addresses the challenges in nondestructive identifying diseases, particularly water-soaked and reddish-pulp disorders, in peaches during storage and transport. Existing technologies have struggled to detect these diseases during this period, leading to potential food loss and consumer distrust. Biospeckle has emerged as a promising discriminator of the internal state of the fruit by utilizing laser-induced scattered light patterns. Pigment interference is minimized by employing lasers with wavelengths of 532 and 650 nm. This study focuses on the ability of biospeckle to distinguish between healthy and diseased fruit based on characteristic values, specifically the Fujii index and cumulative amplitude (Cum. amp.) at 2–3, 3–4, 4–5, and 6–7 Hz. The t-test results demonstrated significant differences in these values, particularly for water-soaked and reddish-pulp disorders. Biospeckle outperforms other non-destructive methods by identifying the symptoms pre-storage. These results indicate that Cum. amp. at 3–4, 4–5, and 6–7 Hz may be more useful in identifying water-soaked fruit than the Fujii index and Cum. amp. at 2–3 Hz. Red lasers are more effective in detecting reddish-pulp disorders than green lasers, which are hindered by pigment absorption. This finding highlights the potential of biospeckle in precise symptom identification, which is crucial for ensuring food quality and consumer confidence.

Production losses in Russian agriculture: Impact on food security and environmental sustainability

This paper provides a quantitative assessment of the impact of losses on specific aspects of food security and environmental sustainability. The lack of full information on the benefits of food loss reduction destimulates developing appropriate effective measures at the public level and in the private sector. The study covers losses generated at the initial stages of the food supply chain, including agricultural production and primary processing. Methodological assessments are based on works of foreign authors, recommendations of the Food and Agriculture Organization of the United Nations (FAO), the Intergovernmental Panel on Climate Change (IPCC) and domestic methodological developments in this area. The results indicate that at the primary stages of the food supply chain, food losses generate a relatively small amount of greenhouse gas emissions, so their reduction in order to lower the carbon footprint is not as effective as at the stage of retail and household consumption. However, preventing losses in agriculture contributes to the creation of additional volumes of food, which can be directed to the consumption of vulnerable groups of population. At the same time, the consequences of loss reduction vary greatly depending on the type of product

Perspectives on Evaluation of Food Banks

Food banks have played an important role in reducing food loss and waste and improving the food insecurity of vulnerable people. This study aimed to carry out a systematic review of food bank evaluation studies and bring new perspectives for future research and decision-making. Ninety-three articles were selected and analyzed from a search on the Web of Science and ScienceDirect platforms. Bibliometric analyses and analyses of the evaluation methodologies were performed. The bibliometric results present the evolution of the studies over the period considered (1994–2024) and indicate how peaks of growth in the number of studies may be related to external events. Both the authors and studied organizations are located mainly in high-income countries. The main aspects considered in the evaluation methodologies are related to the dimensions of short-term impacts and results, indicating less interest in the dimension related to internal processes and activities. This study provides important support for researchers and decision-makers: in addition to presenting, in each dimension of the evaluation, the main indicators used, it raises the questions of the extent to which evaluation studies reflect the reality and context of a given country or region and the extent to which they reflect the management processes of food banks.

A scoping review of food consumer aspects in transitioning to a safe and just agrifood system

Abstract The agrifood system holds the key to identifying potential transformative pathways to achieve prosperity for all within the limits of the planet's natural resources, thereby fostering a safe and just operating system (SJOS) for future generations. The agrifood system is currently not on the right track to meet this ambition. Food-consumer processes such as preference shifts toward healthy diets and substantial reductions in food losses and waste could help to avoid severe environmental degradation and decrease overall mortality, although it remains unclear whether such transitional developments are entirely compatible with socially responsible thresholds. In this paper, we conduct a scoping review approach to map the evidence on the underlying drivers of such demand-side processes in the context of a SJOS with the aim to provide insights on how to transform the EU agrifood system. This review specifically examines how consumer aspects influence the SJOS, rather than exploring the bidirectional relationship. We used a scoping review approach to select relevant studies. The selected papers were subjected to quantitative and qualitative analyses. As a result, we extract insights and draw lessons from the role of food-consumer processes in the transition toward a more SJOS for the agrifood system.

Opportunities for carbon sequestration from removing or intensifying pasture-based beef production

Pastures, on which ruminant livestock graze, occupy one third of the earth's surface. Removing livestock from pastures can support climate change mitigation through carbon sequestration in regrowing vegetation and recovering soils, particularly in potentially forested areas. However, this would also decrease food and fiber production, generating a tradeoff with pasture productivity and the ruminant meat production pastures support. We evaluate the magnitude and distribution of this tradeoff globally, called the "carbon opportunity intensity" of pastures, at a 5-arcminute resolution. We find that removing beef-producing cattle from high-carbon intensity pastures could sequester 34 (22 to 43) GtC i.e. 125 (80 to 158) GtCO2 into ecosystems, which is an amount greater than global fossil CO2 emissions from 2021-2023. This would lead to only a minor loss of 13 (9 to 18)% of the global total beef production on pastures, predominantly within high- and upper-middle-income countries. If areas with low-carbon intensity pastures and less efficient beef production simultaneously intensified their beef production to 47% of OECD levels, this could fully counterbalance the global loss of beef production. The carbon opportunity intensity can inform policy approaches to restore ecosystems while minimizing food losses. Future work should aim to provide higher-resolution estimates for use at local and farm scales, and to incorporate a wider set of environmental indicators of outcomes beyond carbon.

The Effects of International Orientation on the Dimensions of the Environmental Performance of Agri‐Food Companies: A Chilean Perspective

ABSTRACTLike other Latin American economies, Chile has significantly increased its presence in international agriculture markets. Agricultural commodities are primarily developed within specialized exporters or multinational enterprises and exported to several different countries. In Chile, the fruit sector accounts for almost half of total exports. Internationally oriented companies explore business opportunities in foreign markets and invest adequate resources in international operations. In addition, more internationally oriented companies could be more inclined to invest in green practices due to external pressures and, consequently, achieve higher environmental performance. In this context, environmental performance is related to the extent to which available natural resources are protected during the production, delivery, and consumption of agricultural products. To the best of our knowledge, there is scattered evidence of the relationship between international orientation and the environmental performance of agri‐food companies, especially in Latin America. Grounded on the natural resources‐based view theory, this study assessed the effects of environmental collaboration on five dimensions of environmental performance (greenhouse gas emissions, energy efficiency, food loss and waste, food quality and safety, and water footprint management) in agri‐food companies with a survey with Chilean firms. Data were analyzed using the partial least square—structural equation modeling. We found that international orientation positively influences all five dimensions of environmental performance. Our study identified that the dimension most impacted by international orientation is water footprint management, and the least impacted is food quality and safety. With the aid of multi‐group analysis, we concluded that there are no significant differences in these relationships between micro/small and medium/large companies. A significant difference was observed in food loss and waste between fruit and nonfruit producers. We expect the outcomes of this study will support exporting‐related decisions and public policies in Latin America.

Achieving an equitable circular food economy in Vancouver

ABSTRACT Food loss and waste occur at an alarming rate while many households in the City of Vancouver are food insecure. Set within the context of City of Vancouver’s Zero Waste 2040 long-term strategic plan, the City seeks to promote a circular economy, including through food waste reduction and prevention, better food redistribution, and partaking in awareness campaigns. Food rescue and redistribution is often framed as a win–win solution to avoid throwing unwanted, unmarketable, or surplus foods from the landfill and instead redistributing the food to those who are food insecure. This solution has been framed as a useful tool to promote a circular economy. However, both food waste and food studies scholars have rightly noted that connecting unwanted foods with those who are food insecure to address systemic hunger is not a panacea, nor is it a systemic solution to prevent food waste. Drawing on key informant interviews with agri-food experts across the system (n = 20), this study identified the challenges, opportunities, and the overall vision of the circular food economy and how it is mobilised in the City of Vancouver. It seeks to understand how equity factors into the vision of a circular food economy and its implementation by agri-food and relevant actors. The findings in this study highlight the importance of dynamic governance systems that targets critical points for change including regulation, funding, and capacity building to ensure a circular food economy that considers equity and justice.

Integration of renewable energy-powered cold storage solutions for reducing post-harvest food waste in rural agricultural areas

Post-harvest food loss remains a critical challenge in rural agricultural areas, exacerbated by inadequate storage facilities and unreliable energy access. This study develops and optimizes an advanced renewable energy-powered cold storage system tailored for rural settings, integrating solar and wind energy with phase change materials (PCMs) for efficient energy storage. The system incorporates Internet of Things (IoT)-based sensors and artificial intelligence (AI)-driven energy management to maintain optimal storage conditions and enhance energy efficiency. Field trials conducted in Lincolnshire, UK, and Appalachian regions of the US demonstrated significant reductions in post-harvest food loss by an average of 43.5%, extensions in produce shelf-life by up to 300%, and increased income for smallholder farmers by approximately 43%. The system also achieved an 80% reduction in greenhouse gas emissions compared to conventional diesel-powered systems. Economic analyses revealed a shorter payback period and higher return on investment, confirming the system's viability. High user satisfaction and adoption rates indicate the system's practicality and potential for widespread implementation. The findings suggest that integrating renewable energy with smart technologies in cold storage solutions offers a scalable and sustainable approach to enhancing food security, promoting economic growth in rural areas, and supporting environmental objectives globally.

Cardiometabolic outcomes in patients with overweight and obesity undergoing weight loss trials : a network meta-analysis

Abstract Objective Cardiometabolic outcomes are intrinsically linked with obesity. According to a study by Jayedi A et al. a 5kg weight gain could increase CVD mortality and MI risk by 11% and 18% respectively, with most overweight and obese patient also suffering from cardiometabolic derangements. This network meta-analysis evaluates cardiometabolic effects bought about by glucagon-like peptide 1 receptor agonists (GLP-1 RA) and other weight loss drugs in an overweight and obese population. Methods Cochrane CENTRAL, Embase and Medline were searched for randomised clinical trials (RCTs) on GLP-1 RA and United States Food and Drug administration weight loss drugs. A network meta-analysis was performed, using risk ratios(RR) to compare the efficacy of the interventions against one another. Network diagrams and surface under the cumulative ranking curve analysis were generated for the following cardiometabolic outcomes ( LDL, HDL, TC, TG, HbA1c, FPG, SBP and DBP). Results Among the cardiometabolic outcomes analysed, the GLP-1RA’s consistently ranked on top, with tirzepatide followed by semaglutide and then liraglutide. In terms of glycaemic control, tirzepatide 15, 10 and 5mg ranked first in a dose dependent manner(SUCRA = 0.8480, 0.8410, 0.6725) followed by semaglutide1.7mg(SUCRA= 0.6232). Tirzepatide 15mg did not achieve statistical significance compared to semaglutide 1.0mg (MD: -0.77, 95%CI: -2.04 to 0.50) or liraglutide1.8mg (MD: -0.64, 95%CI: -1.68 to 0.41). In reducing blood pressure, tirzepatide exhibiting a dose dependent reduction with Tirzepatide 15mg, (SUCRA =0.9457),10mg(SUCRA=0.9069)and 5mg(SUCRA=0.8419) followed by semaglutide 1.7mg (SUCRA =0.7415) then liraglutide 1.8mg(SUCRA = 0.5521).Tirzepatide 15mg demonstrated statistical significance compared to semaglutide 1.0mg (MD: -3.53, 95%CI: -6.78 to -0.27) and liraglutide 3.0mg (MD: -3.47, 95%CI: -5.59 to -1.36). The GLP-1RA’s also exhibited superiority in lipid reduction for TC and TG, with tirzepatide reducing TC (SUCRA = 0.7867) and TG(SUCRA = 0.9843) followed by semaglutide 1.7 mg (SUCRA = 0.7796) for TC and tirzepatide 10 mg (SUCRA = 0.9018) for TG. Orlistat 120mg(SUCRA =0.8789) and 60mg(SUCRA= 0.8458) were superior in reducing LDL, with tirzepatide 15mg(SUCRA =0.7806) and then semaglutide 2.4mg(SUCRA=0.7260) coming in behind. Naltrexone 32mg/Bupropion 360mg(SUCRA = 0.8757) ranked first followed by tirzepatide(SUCRA=0.8593) in increasing HDL, however the increase was not statistically significant (MD: 0.00, 95%CI: -0.04 to 0.05). Conclusion GLP-1 RAs’ superiority in addressing cardiometabolic parameters that are often deranged in patients with overweight and obesity highlights the need for weight lost medication transitioning from one that decreases and suppresses appetite or prevent the absorption of lipids to one that targets the altered metabolic mileu of patients with overweight and obesity, highlighting the multipronged approach needed to treat this metabolic disease.

Promoting Upcycled Food: An analysis of social media communication strategies of Upcycled Food Association

Global food loss and waste are significant challenges in the food system, critical to addressing food insecurity and national security in the U.S. Upcycled food, which reduces waste at the source, is a promising solution. Social media offers both opportunities and challenges for communicating food benefits. This study examines publicly available data from Instagram, Facebook, and Twitter of a non-profit organization Upcycled Food Association (UFA) using content analysis and machine learning techniques. The analysis revealed that social media posts focused on promoting food waste awareness and benefits related to sustainability, health, and the economy, with environmental information being prioritized. UFA employs diverse impact information frames and uses positive emotion framing to increase food waste awareness and empower consumers by highlighting the impact of their purchasing power. Communication strategies are tailored to the unique characteristics of each social media platform and its users. We recommend social media initiatives continue emphasizing food waste awareness and upcycling, alongside increasing health information to encourage upcycled food consumption. Diverse strategies with diverse benefits and tailored to each platform's characteristics and sociodemographic groups are recommended. Future research can explore efficient topic modeling methods in larger datasets in social media analysis.

The global food security conundrum through the lens of the right to food

Working through the complexities of food insecurity with the intention to address issues requires taking a step back to the drawing board to firm up the understanding of food security through the principles that inform the governance framework of the right to food in the context of the current global food security crisis. Considering the multi-dimensional nature of food security in relation to the right to food alongside concepts such as food sovereignty, and issues such as climate change, food loss and food waste, economic and political turmoil is paramount in determining exactly why all people at all times do not have access to adequate food, or the means for its procurement. This commentary delves into the intricacies of the concept of food security, and the hindrances to realising food security for all by considering what food security is, and where, therefore, the challenges in effecting the right to food are. Through careful consideration of the components of the food security equation, this commentary seeks to show how the right to food comes down to more than ensuring that food is physically available. By connecting the right to food to the factors that affect food security and exploring the ways in which those factors can be broken down and addressed separately, this commentary ultimately advocates for the realisation of food security through collaboration. The consideration of the singular concepts that form the food security equation in solving the multi-dimensional food security problem through conjoined and synchronised efforts influenced by obligations of states and international organisations with mandates directly connected to, and influencing the different aspects of the food security equation. Using reports, statistics, theories and academic opinions, this commentary seeks to explore the different components, which form the concept of food security to draw conclusions and analyse existing systems in an attempt to determine what approaches could be considered in addressing the growing food security crisis and the concerns attached to it.

Upcycling of Food By-Products and Waste: Nonthermal Green Extractions and Life Cycle Assessment Approach

Food loss and waste constitute a substantial threat to global food system sustainability, representing 38% of energy consumption in the supply chain. The 2030 Agenda for Sustainable Development highlights a vision integrating social, economic, and environmental pillars. Addressing environmental impact requires recycling (destruction for new creations) and upcycling (converting waste into valuable products). This review highlights nonthermal green extractions and sustainable techniques in upcycling raw materials such as olives, red beetroot, sugar beet, and coffee, which are widely used in the food industry. Nonthermal processing efficiently extracts bioactive compounds and utilizes waste. Key approaches for its valorization include life cycle assessment, environmental footprint analysis, energy efficiency strategies, digitalization, and sustainability considerations. However, challenges remain in calculating their environmental impact. Waste and by-product valorization from raw materials address disposal issues, offering economic and environmental benefits. Nonthermal techniques show optimistic opportunities in green extraction and sustainable upcycling. The focus is on raw materials including olives, red beetroot, sugar beet, and coffee byproducts, and possible product development. There are powerful connections offering industry tools for impactful sustainability management and guiding decisions on waste-to-value or ‘upcycling’ products. The review contributes to filling the gap in usage of nonthermal processing in upcycling of waste and by-products.

The relationship between iron deficiency and allergic diseases

One of the most important trace elements of the human body is iron. This trace element is the most common on earth, with about a third of the world’s population suffering from iron deficiency. According to WHO, the incidence of iron deficiency in the population can range from moderate - 5-19.9%, to high-more than 40%. The main causes of iron deficiency are: insufficient intake from food, impaired absorption or pathological losses. Allergic diseases can cause the formation of iron deficiency as a result of all of the above causes. At the moment, the relationship between iron deficiency and the development of allergic reactions is being investigated. It is known that functional iron deficiency contributes to the development of allergies and exacerbates the course of symptoms in people with allergies. In this article, we summarize the data on the effect of iron deficiency on the immune processes of the human body and predisposition to the formation of atopy.
