Special Issue Information

Dear Colleagues,

This Special Issue advances the understanding of sustainable agrifood systems by examining links between agricultural production, energy use, emissions, ecological pressures, and consumer and governance behaviours. It covers farm practices, supply chains, and policy frameworks, integrating biophysical, technological, socio-economic, and behavioural perspectives. Its purpose is to identify pathways toward resilient, low-carbon, and energy-efficient agrifood systems, emphasizing agroecological and organic practices that reduce environmental impacts while maintaining productivity and ecosystem integrity.

It complements the existing literature by addressing gaps in energy analysis within agroecological transitions, assessing emissions alongside productivity and biodiversity, and evaluating behavioural and socio-economic drivers of sustainable consumption. By uniting multidisciplinary perspectives, it provides a holistic understanding of agrifood sustainability.

Aligned with Sustainability’s aims, the issue defines and quantifies sustainability metrics, including LCA, carbon footprints, and energy balances; advances methods to monitor performance; incorporates governance, market, and behavioural dimensions; and examines integrated approaches such as agroecology, renewable energy adoption, and policy design. It supports evidence-based sustainability policies aligned with SDGs, including zero hunger, clean energy, responsible consumption, climate action, and life on land.

Topics of interest include (but are not limited to) the following:

  • Life Cycle Assessment of energy use and emissions across farming systems
    • Nutritional quality, safety, and environmental performance of organic and agroecological production
  • On-farm renewable energy technologies and energy-efficiency strategies
    • Soil carbon sequestration, biodiversity conservation, and ecosystem services
    • Sustainable supply chains, consumption behaviours, and food waste reduction
    • Policy frameworks, governance dynamics, and socio-economic drivers
    • Consumer behaviour, sustainability labels, and demand for organic and agroecological products.

This Special Issue promotes holistic, empirically grounded approaches that inform both academic debate and real-world sustainability transitions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Madeira’s agricultural sector is characterised by pronounced structural heterogeneity, land fragmentation, and increasing socio-economic and environmental pressures. However, comprehensive typological and spatial analyses remain limited, particularly in small island contexts. This study addresses this gap by providing a typological and spatial analysis of the agrarian structure in the Autonomous Region of Madeira, Portugal, using 2019 Agricultural Census data. An integrated framework combining Principal Component Analysis (PCA), Partitioning Around Medoids (PAM) clustering, and Random Forest validation—representing a novel approach in agrarian typology studies—is employed to identify three agricultural models: Intensive Subtropical Agriculture (24.1% of parishes), characterised by small holdings and high labour intensity; Extensive Traditional Agriculture (64.8%), featuring moderate farm size and diversified cropping; and Pasture-based Agriculture (11.1%), dominated by larger farms and low labour input. The results confirm significant structural trade-offs, including a strong inverse relationship between farm size and labour intensity (r = −0.653) and a negative correlation between specialisation and crop diversity (r = −0.673). Spatially, the models exhibit clear territorial differentiation, with subtropical systems concentrated in southern coastal areas and traditional systems prevailing in northern and interior regions. These findings support the hypothesis of a hybrid agrarian transition. Despite relying on cross-sectional data, the results provide a robust basis for targeted and place-based policy design within the Common Agricultural Policy (CAP) framework. Full article
