The safeguarding and promotion of food heritage are often considered as a possible way for achieving social and cultural sustainability objectives. This literature review investigates some of the dynamics underlying the heritagisation of food and explores the risks of this process. It focuses mainly on anthropological, geographical, and sociological publications. Overall, it aims to shed light on the strengths and limitations of food heritagisation regarding the improvement of the socio-cultural sustainability of the food system. The analysis highlights cross-cutting risks, namely the omission of tangible and intangible elements of the local food system, and the exclusion of key stakeholders from the recognition and institutionalisation of food heritage. The review highlights the strict interdependence between intangible and tangible elements during food heritagisation, and assesses how local and global interactions can activate and shape this process. It sheds light on the need to pay more attention to the factors, actors, and relationships underpinning the emergence and recognition of food and food-related elements as part of the local heritage.

This article aims to contribute to the limited literature on traditional gastronomic knowledge concerning acorn-based bread by ethnographically documenting the ingredients, preparation techniques and consumption practices of baked goods made from acorn seeds and flour that are still used today or at least still present in living memory. A qualitative comparative case method was adopted, and ethnographic data were gathered from 67 people in six selected Mediterranean, Central Asian and Middle Eastern countries. The analysis highlighted distinct trajectories in the development of acorn-based bread, showing some differences in terms of ingredients, preparation techniques and baking methods in the two cultural and geographical macro-regions. By exploring the evolution of the alimentary role of acorn bread in the past century, our findings also support the hypothesis that the product, at least during the last two centuries, has mostly been used as a famine food. By acknowledging the cultural importance of acorn fruits and acorn-based products, this study suggests that the rediscovery of acorn-based products and associated traditional knowledge may foster the sustainable development of rural and marginal regions in the Mediterranean, Middle East and Central Asia. This could help to reinforce the resilience of local communities and thus increase food security. Furthermore, reassessing acorns as a foodstuff may aid in developing innovative products in line with emerging trends in the food sector, which is looking for new non-cereal-based bakery products and other novel culinary applications.

The article investigates the link between food festivals and traditional food knowledge and explores the role played by tourist events in disseminating local agricultural and gastronomic knowledge. This article presents the ethnographic case of the Pink Asparagus Festival in Mezzago in Italy, analyzing how the festival supported the continuation of crop production and its associated traditional knowledge in the village. In the face of a decline of asparagus production, the article highlights the role of the festival in fostering a revival of local food knowledge, which is also able to embrace modernization, at the same time maintaining a strong sense of the past and Mezzago's legacy. Thus, the article suggests that festivals are not just events aimed at commodifying local knowledge, but can be important tools to refresh and maintain local expertise, which is vital and pressing in the context of modern society, and strengthen and expand the relationship between members of the community, thus converting the festival into an endeavor to foster sociocultural sustainability.

In the last decades, scholars from different disciplines have used the foodscape as a concept and an analytical framework to explore the intersection between landscape, people and food culture. Adopting a comparative case-study analysis, this article aims to show how a foodscape can be used as a lens to investigate cultural landscapes, specifically in mountain areas affected by fast structural socio-economic and ecological changes, identifying key tangible and intangible elements, the underpinning relationship and values, as well as the factors underlying their evolution and transformation. In this way, the article indicates this concept as a key tool for landscape management and conservation. We discuss three different and complementary approaches to the analysis of cultural landscapes, namely, from food products to landscape analysis (Albania), from food production practices to landscape analysis (Kenya) and from food-related rural architecture to landscape analysis (Italy). Overall, the research highlights how implementing a foodscape lens among the different levels of landscape analysis could contribute to the assessment, protection and promotion of local food-related resources. In so doing, it opens new research aimed at defining the limits of this heuristic instrument, where its most promising aspects of the foodscape have been explored in the article.

Background: Initiatives for beekeeping intensification across the tropics can foster production and income, but the changes triggered by the introduction of modern beehives might permeate traditional knowledge and practices in multiple ways, and as such should be investigated and understood. We conducted an ethnobotanical study in the Eastern part of the Mau Forest among Ogiek beekeepers who customarily practice forest beekeeping and who are involved in a project aimed at the modernization of their beekeeping activities. We aimed to document the beekeeping-associated ethnobotanical knowledge, exploring the relationships and complementarity between modern and traditional knowledge and practices. Methods: Field research was carried out through semi-structured interviews with 30 Ogiek beekeepers and 10 additional stakeholders. We collected ethnobotanical data about plants used for beekeeping purposes, and ethnographic information on traditional and modern beekeeping systems. Results: We report 66 plant species, distributed across 36 botanical families representing 58 genera, important as melliferous, for the construction and placing of hives, attracting bees, and harvesting and storing honey. Dombeya torrida (J.F.Gmel.) Bamps, Juniperus procera Hochst. ex Endl., and Podocarpus latifolius (Thunb.) R.Br. ex Mirb. are the species with the most mentions and the highest number of uses. Our study reveals that the Ogiek possess a detailed knowledge of the forest’s flora, its importance and uses and that this knowledge underpins beekeeping practices. Under the influence of external actors, the Ogiek have progressively adopted modern versus traditional log hives and moved beekeeping out of the forest into open areas of pastures and crop fields. Beekeepers are also experimenting with combinations of practices borrowed from modern and traditional beekeeping systems, particularly in the field of hive construction and in the criteria to set up apiaries. Conclusions: The study indicates a complementarity and an incipient hybridization of traditional and modern beekeeping, in a way that suggests that modern beehives are instrumental in expanding the reach of beekeeping into deforested and cultivated areas. The study also points to the existence of a rift in the effects of beekeeping intensification on the livelihoods of the Ogiek and on their relationship with the forest. We argue that this intensification might be improving the former but weakening the latter, carrying the associated risk of erosion of traditional forest-based ethnobotanical knowledge.

The current study reports an ethnobotanical field investigation of traditionally gathered and consumed wild greens (Chorta) in one of the five so-called Blue Zones in the world: Ikaria Isle, Greece. Through 31 semi-structured interviews, a total of 56 wild green plants were documented along with their culinary uses, linguistic labels, and locally perceived tastes. Most of the gathered greens were described as bitter and associated with members of Asteraceae and Brassicaceae botanical families (31%), while among the top-quoted wild greens, species belonging to these two plant families accounted for 50% of the wild vegetables, which were consumed mostly cooked. Cross-cultural comparison with foraging in other areas of the central-eastern Mediterranean and the Near East demonstrated a remarkable overlapping of Ikarian greens with Cretan and Sicilian, as well as in the prevalence of bitter-tasting botanical genera. Important differences with other wild greens-related food heritage were found, most notably with the Armenian and Kurdish ones, which do not commonly feature many bitter greens. The proven role of extra-oral bitter taste receptors in the modulation of gastric emptying, glucose absorption and crosstalk with microbiota opens new ways of looking at these differences, in particular with regard to possible health implications. The present study is also an important attempt to preserve and document the bio-cultural gastronomic heritage of Chorta as a quintessential part of the Mediterranean diet. The study recommends that nutritionists, food scientists, and historians, as well as policymakers and practitioners, pay the required attention to traditional rural dietary systems as models of sustainable health.
