Sustainable Gastronomy: the Environmental Impacts of How We Cook Now and How the “Sustainable Diets” Agenda Might Shape How We Cook in the Future?

The 2019 Eat-Lancet report has proposed a global healthy sustainable diet, which would provide not only for human health but also sustain a healthy planet. The main recommendations are to increase consumption of healthy foods (such as vegetables, fruits, whole grains, legumes, and nuts), and a decrease in consumption of unhealthy foods (such as red meat, sugar, and refined grains). A critique of the EAT-Lancet diet is that it lacks consideration of local and traditional diets, food ways or systems of production, and the report has limited suggestions for how a global healthy sustainable diet could be implemented (Edman et al., 2019; Jonas, 2019; Torjesen, 2019). This paper firstly explores the sustainability impacts of cooking food, and how different foods have different environmental impacts from production, consumption, and cooking. It reports on a 2019 survey of cooking methods and habits in the UK, Australia and USA, examining how these different nations’ unique culinary and cooking habits lead to different environmental impacts. This paper then examines what dietary shifts are being recommended by current academic literature, and how these dietary shifts may change the methods of cooking in the future

Understanding 1968: the case of Brest

This article examines the dominance of Paris in how May '68 has been portrayed over the years. It will be argued, through a case-study of the revolt in the Breton city of Brest, that the Paris-centred approach is one that belies the true nationwide aspect of May/June 1968. As one of a range of characteristics, the concentration on the Latin Quarter has helped mould what Kristin Ross has described as the 'official history' of 1968. An examination of how the events were played out within different regional contexts would go a long way towards helping overcome the shortcomings of the increasingly narrow portrayal that has come to dominate the stereotypical image of 1968

Temporal variation in Plio- Pleistocene Antidorcas (Mammalia: Bovidae) horncores: the case from Bolt's Farm and why size matters

Morphological differences in samples of fossil (Antidorcas recki) and modern (A. marsupialis) springbok horncores suggest that the ancestral species shows less sexual dimorphism than is observed in the horn dimensions of modern springbok. This pattern may prove useful when evaluating fossil springbok specimens in South African Plio-Pleistocene faunal assemblages. Undated Antidorcas craniodental specimens from Pit 3, Bolt's Farm (Cradle of Humankind, Gauteng, South Africa) have previously been referred to A. recki by Cooke.l However, comparison with numerous other springbok samples suggests that these specimens are more likely to represent male and female fossils of the extant species, A. marsupialis. This re-evaluation adds weight to the fossil evidence implying that the modern form of springbok is a southern African endemic species which first appeared around 1.5-1.0 million years ago in Swartkrans Member 1. Bolt's Farm Pit 3 fossils are inferred to be of a similar age

Morphological evaluation of genetic evidence for a Pleistocene extirpation of eastern African impala

Palaeontology typically relies on fossil studies, in particular morphological differences, to reconstruct and interpret patterns of vertebrate evolution. However, genetic studies of population histories of extant species provide data about past population events (e.g. local extinctions, recolonisations) which are equally relevant to palaeontological questions. This study used morphological traits to evaluate a hypothesis based on genetic evidence that southern African impala (Aepyceros melampus) are the founder population for all other living African impala populations, after an eastern African extirpation event dating to around 200 000 years ago. Measurements of three horn metrics and the presence or absence of a particular dental trait were compared across four regional impala samples. Eastern African impala possess a unique combination of larger horns and a signiicantly higher occurrence of entostyles when compared to other impala populations. These traits are likely to have characterised a small group of founding impala which recolonised this region. This pattern appears consistent with the genetic evidence that a subset of the southern African impala gave rise to the eastern African populations. Other species with complex population histories, such as wildebeest, eland, topi and hartebeest may also therefore be expected to express variation in certain morphological traits in the fossil record because of similar patterns of recolonisations. The process of local extinction and subsequent repopulation over shorter timescales may pass unnoticed in the fossil record, and lineages may appear uninterrupted. Instead, greater morphological variation within a species may be observed, which may be misinterpreted as reflecting a speciation event, or ecophenotypic variation. Combining data from genetic studies and palaeontology may provide further clues as to how faunal dispersals within Africa shaped the morphological variation in the fossil record, and how to best interpret such differences

Nyctereutes terblanchei: The raccoon dog that never was

Fossils of the raccoon dog (genus Nyctereutes) are particularly rare in the African PlioPleistocene record, whilst the sole living representative, Nyctereutes procyonoides, is found in eastern Asia and parts of Europe. In southern Africa, only one fossil species of raccoon dog has been identiied – Nyctereutes terblanchei. N. terblanchei is recognised from a handful of Plio-Pleistocene sites in South Africa: Kromdraai, Kromdraai–Coopers and Sterkfontein in Gauteng, as well as Elandsfontein in the Western Cape Province. The validity of this species identiication was questioned on the basis of the rarity of southern African fossils assigned to Nyctereutes, that is, fewer than 10 specimens have been identified as Nyctereutes. This study examined this fossil sample of the raccoon dog from the Gauteng sites and compared dental and cranial metrics of the fossil with samples of modern canids and published data. Morphological traits used to distinguish Nyctereutes, such as the pronounced subangular lobe on the mandible and the relatively large size of the lower molars, were observed to be variable in all samples. Analysis showed that the size of the dentition of the southern African fossil samples was larger than that of living raccoon dogs, but fell well within the range of that of African jackals. These results suggest that fossil Nyctereutes cannot be distinguished from other canid species based on metric data alone, and may only be diagnosable using combinations of non-metric traits of the dentition and skull. However, based on the degree of morphological variability of the traits used to diagnose Nyctereutes, as well as the rarity of this genus in the African fossil record, these fossils are more likely to belong to a species of jackal or fox
