Cowpea (Vigna unguiculata [L.] Walp) is a vital food security crop in sub-Saharan Africa, including Eswatini. The productivity of the crop is low (<600 kg/ha) in the country due to a lack of improved, locally adapted, and farmer-preferred varieties with biotic and abiotic stress tolerance. The objective of the study was to assess the agronomic performance of newly developed elite cowpea mutants to select best-yielding and adapted pure lines for production and genetic improvement in Eswatini. A total of 30 cowpea genotypes, including 24 newly developed advanced mutant lines, their 3 founder parents and 3 local checks, were profiled for major agronomic traits in two selected sites (Lowveld Experiment and Malkerns Research Stations) using a 6 × 5 alpha lattice design with three replications. A combined analysis of variance revealed that the genotype x location interaction effects were significant (p < 0.05) for germination percentage (DG %), days to flowering (DTF), days to maturity (DMT), number of pods per plant (NPP), pod length (PDL), number of seeds per pod (NSP), hundred seed weight (HSW), and grain yield (GYD). Elite mutant genotypes, including NKL9P7, BRR4P11, SHR9P5, and NKL9P7-2 exhibited higher grain yields at 3158.8 kg/ha, 2651.6 kg/ha, 2627.5 kg/ha, and 2255.8 kg/ha in that order. The highest-yielding mutant, NKL9P7, produced 70%, 61%, and 54% more grain yield than the check varieties Mtilane, Black Eye, and Accession 792, respectively. Furthermore, the selected genotypes displayed promising yield components such as better PDL (varying from 13.1 to 26.3 cm), NPP (15.9 to 26.8), and NSP (9.8 to 16.2). Grain yield had significant positive correlations (p < 0.05) with DG %, NSP, and NPP. The principal component analysis (PCA) revealed that 81.5% of the total genotypic variation was attributable to the assessed quantitative traits. Principal component (PC) 1 accounted for 48.6%, while PC 2 and PC 3 contributed 18.9% and 14% of the overall variation, respectively. Key traits correlated with PC1 were NPP with a loading score of 0.91, NSP (0.83), PDL (0.73), GYD (0.68), HSW (0.58), DMT (−0.60), and DTF (−0.43) in a desirable direction. In conclusion, genotypes NKL9P7, BRR4P11, SHR9P5, NKL9P7-2, Bira, SHR3P4, and SHR2P7 were identified as complementary parents with relatively best yields and local adaptation, making them ideal selections for direct production or breeding. The following traits, NPP, NSP, PDL, GYD, and HSW, offered unique opportunities for genotype selection in the cowpea breeding program in Eswatini. Full article

Choosing a rural destination today often comes down to one thing: how authentic it feels. In countries like Romania, where tradition is still woven into daily life, travelers are looking for something real and sustainable—but what exactly does that mean? And how can we measure it? This study takes a different approach. We created an Authenticity Index using fuzzy logic, a method that makes space for in-between answers and soft boundaries. It helped us capture how people actually perceive things like local food, architecture, and natural scenery—without forcing their opinions into rigid categories. We tested the index with real guest feedback from rural accommodation. The results showed that guests consistently valued sensory experiences—like nature and food—more than activities that required deeper cultural involvement, such as workshops or folk demonstrations. Instead of just producing a number, the index turned out to be a guide. It gives hosts a better idea of what really matters to their guests—even when those preferences are not always easy to define. More than that, it brings together what theory says with what visitors actually feel, supporting more sustainable tourism practices. And in rural tourism, that connection can make all the difference.

Vinegar functions not only as a sensory enhancer but also as a culturally embedded culinary element across global food systems. In Taiwanese cuisine, black vinegar represents a traditional staple, particularly associated with dumpling consumption, whereas Italian balsamic vinegar is renowned for its aromatic complexity and nuanced sweetness, highly esteemed in Western gastronomy. Despite their culinary significance, limited empirical research has examined how these culturally distinct condiments are perceived when applied beyond their traditional contexts, especially in iconic national dishes. This study investigates Taiwanese consumers’ cross-cultural sensory responses to dumplings paired with either local black vinegar or imported balsamic vinegar. Through a structured sensory evaluation encompassing appearance, aroma, taste, and overall impression, this research explores how sensory cues and cultural expectations interact to shape flavor preferences. The results indicate that although visual attributes were rated similarly, balsamic vinegar’s distinctive aroma and taste elicited significantly greater sensory engagement, suggesting a latent openness to reinterpretation and hybridization within established food practices. These findings were supported by one-way ANOVA results, which revealed significant differences among the three groups for aroma (F = 6.30, p < 0.01), taste (F = 7.21, p < 0.01), and overall evaluation (F = 15.15, p < 0.001). By integrating sensory analysis with cultural food studies, this research advances the understanding of how multisensory cues influence consumer acceptance across cultural contexts. It further highlights the dynamic interplay between cultural familiarity and sensory novelty in flavor perception. These insights yield practical implications for culinary innovation, global flavor localization, and the development of culturally responsive food products. Full article

Sustainability has also become an increasingly important issue as an international trend for the hospitality industry in recent times, with a positive message for both restaurant operators and consumers. Restaurants can become more sustainable in three main areas: (1) water and energy efficiency, (2) waste management, and (3) employees—social topics. This study examines the role of green practices and innovation in hospitality using three methods in parallel. In connection with a current tourism project, this paper describes some of the green practices for hospitality management in Hungary. Based on the survey, the most common sustainable practices are sourcing from local producers and using seasonal menus. The most popular food waste reduction strategies are Munch, nose-to-tail, and other food utilization options, totaling 65.0%. A total of 72.0% of consumers prefer the green restaurants. Our data show that sustainable operation is not just an environmental issue, but also increasingly a strategic business advantage. The findings are supported by the everyday practices of two of Dining Guide’s member restaurants, Iszkor and Sulyom in the Northeastern Hungary region. Both restaurants focus on locally sourced food and drink ingredients. Some dairy products, domestic fruit, and vegetables come from sustainable farming. For restaurants, adopting sustainable solutions can provide a long-term competitive advantage. Full article

Addressing the interconnected challenges of food security, climate change, and population growth requires innovative and adaptive approaches to sustainable agriculture. Agricultural best management practices (BMPs) provide a promising framework for enhancing resilience, improving resource efficiency, and promoting biodiversity. However, the effectiveness of BMPs’ implementation largely depends on their alignment with local environmental, social, and economic conditions. This study presents a novel methodology for selecting and implementing BMPs based on stakeholder preferences, ensuring solutions are contextually relevant and widely accepted. Developed within the European Commission-funded WATDEV project, this methodology integrates a bottom-up and top-down decision-making framework, incorporating the perspectives of farmers, policymakers, and experts. The approach has been tested in four East African countries: Kenya, Ethiopia, Sudan, and Egypt, demonstrating its adaptability across diverse agroecological settings. Through a structured assessment involving stakeholder engagement, data-driven BMP selection, and participatory decision support tools, the study identifies and prioritizes BMPs that optimize water use, soil conservation, and climate resilience. Findings highlight that community-driven BMP selection enhances adoption rates and ensures solutions are technically feasible, economically viable, and environmentally sustainable. The methodology provides a scalable blueprint for integrating stakeholder preferences into agricultural planning, offering valuable insights for policymakers, researchers, and practitioners working toward sustainable food systems in East Africa and beyond.

Seaweeds represent a vital yet often understudied component of the diet and cultural heritage of many coastal communities globally. This study investigated seaweed consumption practices in coastal communities of Tawi-Tawi, Philippines, through one-to-one interviews (n = 280) and focus group discussions (n = 7). The study revealed that nearly all (99%) of the population consumes seaweeds, with women comprising the majority of consumers who have done so since childhood (68% female vs. 32% male). These consumers were predominantly married (79%), within the 21–40 age group (53%), with families of 5–7 members (43%), practicing Islam (97%), and belonging to the Sama tribe (71%). A significant portion (48%) had resided in the area for 21–30 years, attained elementary to high school education (66%), and had a monthly income ranging from 1000 to 10,000 Philippine pesos (72%). Seaweed consumption was a family-wide practice (88%), including children, who typically started around 4–8 years old (61%), driven by perceived nutritional benefits (43%), preferred flavor (80%), affordability (19%), ease of preparation (33%), and cultural integration (23%). The primary edible seaweeds identified were Kappaphycus alvarezii (63%), K. striatus (58%), Kappaphycus spp. (47%), Eucheuma denticulatum (57%), Caulerpa lentillifera (64%), Caulerpa spp. (51%), C. cf. macrodisca ecad corynephora (45%), C. racemosa (30%), and Solieria robusta (49%), with less frequent consumption of K. malesianus (8%), Chaetomorpha crassa (3%), Gracilaria spp. (0.72%), and Hydroclathrus clathratus (0.36%). Specific plant parts were preferred for certain species, and preparation predominantly involved raw (75%) or cooked (77%) salads with spices, primarily prepared by mothers (72%). Consumers generally avoided seaweeds showing signs of ice-ice disease (95%), pale coloration (91%), or epiphyte infestation (84%). Consumption frequency was typically 1–3 times per week (45%), with knowledge largely passed down through generations (95%). Seaweed salads were primarily consumed as a viand (92%) at home (97%), with locals perceiving seaweed consumption as contributing to a healthy diet (40%) and overall well-being [e.g., aiding hunger (76%), improving digestion (20%), preventing obesity (14%), and aiding brain development (3%)]. The study’s findings emphasize the significant yet often overlooked role of seaweeds in the food systems and cultural heritage of Tawi-Tawi’s coastal communities. Future efforts should prioritize the sustainable management of wild resources, explore the cultivation of diverse edible species, and enhance nutritional awareness. Further research into traditional seaweed knowledge holds broader value. Full article

This study investigates consumer preferences and willingness to pay (WTP) for antioxidant-rich pomegranates, focusing on the roles of product attributes and generational differences. A survey of 3019 Italian consumers assessed consumption habits, perceived barriers, and WTP for antioxidant-enriched pomegranates. A Best–Worst Scaling (BWS) analysis was used to identify key product attributes, and generational segmentation highlighted differences in consumer behavior. The results reveal a strong preference for locally sourced pomegranates and a high valuation of health-related attributes, particularly antioxidant content. However, several consumption barriers emerged, including taste preferences, peeling difficulty, and limited product availability. While older generations, especially Baby Boomers, prioritize antioxidants for their health benefits, younger generations (Gen Z and Millennials) showed the highest WTP for antioxidant-enriched pomegranates, likely influenced by novelty seeking and engagement with food trends. These findings suggest that marketing strategies should emphasize both local origins and health benefits. From a policy perspective, supporting local agriculture and promoting the nutritional value of enriched foods could enhance consumer acceptance and expand the market potential. Full article

Rice (Oryza sativa L.) is essential for global food security and sustains billions worldwide, emphasizing the need to improve production and quality. One key challenge in rice breeding is the inheritance and environmental sensitivity of amylose content, a starch component that influences the texture, water absorption, and firmness after cooking, which are crucial for market acceptance. While international markets prefer low-amylose varieties for their softness, intermediate- and high-amylose varieties are favored in Latin America for their firmness. The objective of this study was to develop a molecular quality assessment methodology that, combined with morphological and culinary evaluations, helps in the selection of rice varieties during the breeding process. First, ten Ecuadorian rice materials were evaluated for milling and culinary quality characteristics, revealing significant grain size, sterility, milling yield, cooking time, and texture variations. Amylose content (AC) is genetically regulated by the waxy gene and its allelic variants, affecting granule-bound starch synthase (GBSS) enzyme expression. Secondly, to classify rice varieties molecularly based on AC, the testing ten genotypes plus nine control varieties were analyzed using microsatellite (SSR) markers. The waxy molecular marker, combined with metaphor agarose gel electrophoresis (MAGE), proved effective for early-stage AC analysis, reducing variety selection costs and improving breeding efficiency. Additionally, a restriction enzyme protocol assay facilitated variety differentiation by selectively cleaving the waxy gene sequence at a specific single-nucleotide polymorphism (SNP) site, allowing for precise AC genetic classification. By integrating molecular techniques with traditional assessments, this study reveals that using marker-assisted selection in breeding programs, as well as supporting the identification and development of high-quality local rice varieties to meet market demands, improves production efficiency and optimizes the assessment of developing varieties under diverse environmental conditions.

The study of Sustainability Transitions (STs) has emerged as an interdisciplinary research field aimed at understanding and guiding societal transformations toward sustainability. While significant advancements have been made in analyzing socio-technical, economic, and policy dimensions, spatial aspects of STs have been largely overlooked. This study contributes to the field by conducting a systematic literature review and bibliometric analysis of academic research on the Geography of Sustainability Transitions (GST). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) framework, this study identified and analyzed 63 scientific publications indexed in SCOPUS (1995–2024) to examine trends, regional distribution, author profiles, thematic focuses, and main advances. Results highlight a concentration of research in the Global North, with major contributions from Europe and North America, while studies from the Global South remain scarce. The analysis also reveals six dominant transition themes: urban transitions, energy transitions, industrial transitions, transport transitions, circular economy, and agri-food transitions. Each of these themes is discussed in terms of spatial dynamics, governance mechanisms, and the role of regional contexts in shaping transition pathways. The study underscores the need for a more spatially inclusive approach in transition research, advocating for greater integration of geographical perspectives in sustainability studies. Future research should emphasize the role of local and regional factors in transition processes, addressing disparities in transition capabilities between different territories. By doing so, this work contributes to a more comprehensive understanding of how STs unfold across diverse spatial contexts. Identifying the observed research gaps, the study acts as a catalyst for interdisciplinary analytical reasoning and reinforces the geospatial effect within the broader field of STs. Full article

The intensification of agricultural practices, such as the extensive use of synthetic fertilizers, the expansion of irrigation systems, and land use conversion, has led to substantial biodiversity loss and the disruption of ecosystem functions. Traditional washing procedures for fresh produce involve substantial water usage and can generate wastewater, which requires proper management to prevent environmental contamination. By skipping the washing stage, these reduced water and energy inputs contribute to more sustainable agricultural practices. Although this approach may benefit sustainability and the environment, the market success of a product with a sustainable attribute ultimately depends on consumer acceptance and their willingness to pay (WTP) for it. This study investigates consumer preferences and WTP for a local potato variety called “Agria”, with a specific focus on the sustainability attribute concerning the sale of washed versus unwashed potatoes. We conducted an experimental study with consumers in northeastern Spain, where this potato variety is grown, and simulated market shares under varying price scenarios. The methodology involved a choice experiment that evaluated three characteristics: price, local origin, and presentation (washed versus unwashed). The methodology also incorporated attribute non-attendance (ANA) to capture all aspects of the decision-making process. The findings reveal that consumers preferred the locally grown variety over those from other origins and were willing to pay a premium. Although consumers preferred washed potatoes, they would purchase unwashed potatoes at a discount price of EUR 0.2/kg. The results provide marketing and pricing strategies for local producers and retailers and market share projections aligned with consumer preferences for local food. Empirically, the study contributes to the literature on consumer preferences and sustainable food systems by (i) integrating the “washed versus unwashed” attribute with local origin to inform more effective marketing strategies; and (ii) supporting local potato growers through the identification of viable lunch strategies for a differentiated, unwashed product that extends shelf life, reduces food waste, and promotes sustainability by lowering water and energy use in post-harvest processing. For methodologically, it applies ANA in the context of potato choice experiments—an approach rarely used in this domain—to enhance the understanding of consumer decision-making. Full article

This study explores the relationship between climate change awareness (CCA) and consumers’ willingness to pay (WTP) for urban short food chains (USFC), focusing on the mediating role of biospheric, egoistic, and altruistic environmental concerns. A structured questionnaire was conducted with 230 respondents in Tirana, Albania, and the results were analysed using the PROCESS macro in SPSS 25.0. The findings reveal that CCA increases all three environmental concerns; however, only the altruistic concern significantly mediates USFC participation, particularly by limiting food waste (effect size = 0.502, p = 0.002). In contrast, egoistic concern negatively affects WTP, highlighting a value–action gap in sustainable behaviour. Reducing ultra-processed food consumption emerges as a key driver of engagement, linking personal and environmental health to local food choices. Gender moderates these relationships; despite showing high ecological concern, women express lower WTP due to household and budgetary considerations. Supporting the model, the survey data show that 88% of respondents are willing to pay a premium, typically 10–20% more, for food products from their preferred origin, and 88% are also willing to participate in the Tirana USFC initiative. The highest WTP (30%) is reported among highly educated women with children aged three to five. These findings highlight the need for targeted urban food policies that account for sustainability’s psychological and demographic dimensions. Full article

Goat farming represents a critical component of rural livelihoods, food security, and cultural heritage in southeastern Tunisia. This study adopts a multi-stakeholder approach to analyze the goat value chain in Tataouine, incorporating focus groups, semi-structured questionnaires, and direct observations with 80 farmers, 3 veterinarians, 13 butchers, and 100 consumers. The findings reveal strong local demand, with 72% of consumers purchasing goat meat and 66% consuming milk. However, significant inefficiencies exist, particularly a misalignment between production and market requirements: while 92% of butchers prefer fattened animals, only 16% of farmers engage in fattening practices. Women constitute 49% of dairy processors, yet face persistent resource constraints. Climate pressures exacerbate these challenges, with 80% of farmers reporting water scarcity and 93.8% observing pasture degradation. Three strategic interventions emerge as pivotal for sustainable development: targeted support for feed-efficient fattening techniques, establishment of women-led dairy processing collectives, and implementation of climate-resilient water management systems. These measures address core constraints while leveraging existing strengths of the production system. The study presents a transferable framework for livestock value chain analysis in arid regions, demonstrating how integrated approaches can enhance both economic viability and adaptive capacity while preserving traditional pastoral systems.

The Araceae family exhibits remarkable morphological and ecological diversity, playing a significant role in horticulture, agriculture, and traditional practices. Despite Thailand’s rich aroid diversity, Kalasin Province remains underexplored in terms of species distribution, ecology, and local utilization. This research aimed to document the diversity, habitat preferences, and local uses of Araceae in Kalasin Province. Field surveys, herbarium studies, and interviews with local communities were conducted to record species occurrences and assess their applications. A total of 51 species, representing 24 genera and 5 subfamilies, were identified, with 13 species found in the wild and 43 in cultivation. Wild species demonstrated pronounced ecological specialization, thriving in natural habitats, while cultivated species dominated across all districts, reflecting socio-economic and cultural influences. All recorded species were utilized in at least one category, including food, medicine, ornamental purposes, and cultural practices. Notably, Alocasia macrorrhizos and Colocasia esculenta were the most extensively used, contributing to multiple utilization categories. This study also proposed preliminary conservation status of wild species, with several species proposed as Vulnerable due to habitat degradation and limited distribution. These findings contribute to a better understanding of Kalasin’s aroid flora and emphasize the importance of conservation efforts in the face of agricultural expansion and habitat alteration. This study provides a foundation for the sustainable management and preservation of Araceae biodiversity in northeastern Thailand. Full article

Traditional cereals, recognised for their adaptability, high nutritional value, and unique sensory characteristics, have largely been excluded from global food supply chains. Recent shifts in consumption patterns, particularly in urban areas, indicate a growing demand for high-quality bread, creating new opportunities for farmers interested in sustainable production techniques and traditional varieties. However, challenges such as seed availability, regulatory constraints, marketing strategies, and logistical barriers persist. This study, conducted within the framework of the CERTRA project—Development of Traditional Cereal Value Chains for Sustainable Food in Portugal—aims to enhance the traditional cereal value chain in Portugal by identifying key challenges and opportunities and proposing effective development strategies. The research employs a mixed-method approach, including documentary research, a SWOT analysis based on the scientific literature and stakeholder insights, and a case study methodology examining twelve successful European initiatives. The findings highlight strengths such as seed sovereignty, resilience under low-input farming, and market potential through certification and short food supply chains. However, weaknesses such as lower yields, mechanisation challenges, and seed access restrictions remain critical obstacles. Our analysis suggests that participatory breeding programs, farmer-led seed networks, and hybrid distribution models integrating direct sales, online platforms, and local partnerships can support the revitalisation of traditional cereals. Future research should focus on consumer preferences, branding strategies, and technological innovations that enhance processing efficiency while preserving the ecological and cultural value of traditional varieties.

Scenario planning is a potentially effective method for supporting long-term planning for sustainable and resilient food systems; however, scenario exercises are often limited by too much focus on a single preferred future, not accounting for uncertainty in global trajectories and future conditions. This study engaged local food system actors in Revelstoke (Canada) in a workshop that explored a qualitative, scenario-based approach to long-term food systems planning in the face of uncertain futures. The study involved applying different global narratives to identify future local scenario alternatives that respond to the socioeconomic, environmental, and political pressures in these narratives. This study identifies two trajectories and sets of possible future conditions (i.e., Scenario 1 and Scenario 2) that differ from one another in the following areas: (1) health and wellbeing, (2) connectivity and scale, (3) human–environment interactions, and (4) economies and the nature of work. Additionally, the strengths and weaknesses of the qualitative scenario method developed and used in this study were identified, including considerations related to the application of the method, participant selection, the nature of the data, and the assessment (or lack thereof) of the likelihoods of future events. The insights from such a scenario-planning approach can be used to stimulate thinking about what actions and interventions are useful for making progress toward local wellbeing, sustainability, and resilience in the face of global challenges and exogenous shocks.
