    Introducing a degrowth approach to the circular economy policies of food production, and food loss and waste management: towards a circular bioeconomy
    (MDPI, 2021-03-02)
    There is a growing debate surrounding the contradiction between an unremitting increase in the use of resources and the search for environmental sustainability. Therefore, the concept of sustainable degrowth is emerging aiming to introduce in our societies new social values and new policies, capable of satisfying human requirements whilst reducing environmental impacts and consumption of resources. In this framework, circular economy strategies for food production and food loss and waste management systems, following the Sustainable Development Goals agenda, are being developed based on a search for circularity, but without setting limits to the continual increase in environmental impacts and resource use. This work presents a methodology for determining the percentage of degrowth needed in any food supply chain, by analyzing four scenarios in a life cycle assessment approach over time between 2020 and 2040. Results for the Spanish case study sug-gested a degrowth need of 26.8% in 2015 and 58.9% in 2040 in order to achieve compliance with the Paris Agreement targets, highlighting the reduction of meat and fish and seafood consumption as the most useful path.

    A critical review on food loss and waste quantification approaches: Is there a need to develop alternatives beyond the currently widespread pathways?
    (Elsevier BV, 2022-09-27)
    In a context of increasing concern regarding food loss and waste (FLW) generation, different attempts have been made to standardize quantification methodologies. On the one hand, an important number of small-scale studies have been published that constitute direct measurement methodologies. On the other hand, the FAO Food Balance Sheets, which aggregate some of the prior studies, provides an indirect metric that has been applied using FLW coefficients in numerous food-related studies. However, to date, no standard methodology has been agreed upon to quantify FLW. This study performs an assessment of 237 studies in the field, aiming to identify existing FLW quantification methodologies, and if there is a need of developing alternative paths. Firstly, a descriptive review was performed. Secondly, an assessment of critical point of views was presented. For this, different critical voices in the scientific literature were retrieved, some of which highlight the high level of uncertainty and a certain degree of opacity in some of the most widespread FLW quantification and assessment reports. In this line, essential elements of quantification are being omitted. Moreover, the focus is being excessively placed on the role of the consumer, compared to the role played by agribusiness and large distribution chains.

    Current practices and key challenges associated with the adoption of resilient, circular, and sustainable food supply chain for smallholder farmers to mitigate food loss
    (Frontiers Media, 2025-01-01)
    Introduction In response to increasing global food insecurity, resilient, circular, and sustainable practices hold significant potential to enhance food supply chain performance and reduce food loss. This study examines the current practices and key challenges faced by Peruvian smallholder farmers in managing a resilient, circular, and sustainable food supply chain, proposing a hybrid model that integrates ancestral agricultural knowledge with modern innovations. Methods Using a qualitative approach, in-depth interviews were conducted with 16 smallholder farmers from various regions of Peru. Participants were selected through purposive sampling, focusing on farmers who apply organic agricultural techniques. Data were analyzed using content analysis techniques supported by ATLAS.ti 23 software to identify patterns in practices and challenges. Results The findings reveal that farmers operate within short supply chains, without intermediaries, applying intuitive practices aligned with circular economy principles, including Rethink, Redesign, Reduce, Replace, Reuse, Repurpose, and Recycle, but excluding Recovery. While social and economic dimensions are prioritized, current practices are insufficient to ensure long-term sustainability. Key challenges include technological limitations, restricted market access, and low consumer awareness. Discussion A hybrid model is proposed, combining resource-efficient technologies with culturally rooted practices, fostering multi-stakeholder collaboration. This approach addresses identified gaps and contributes to food security, environmental sustainability, and the achievement of Sustainable Development Goals 1 (No Poverty), 2 (Zero Hunger), and 12 (Responsible Consumption and Production).
