Abstract

Climate changes are a serious threat to cultural and natural heritage. Although many contexts are today seriously endangered, recent studies highlight how “archaeology and cultural heritage threatened by anthropogenic climate change are not just victims but part of the solution” (Hambrecht & Rockman, 2017. American Antiquity). Long-term archaeological projects could provide evidence to better understand the nature of the relations between climatically driven environmental changes and social trajectories. Aim of this talk is to present a synthesis of the main Holocene climate and environmental variations from a privileged geographical context – the central Sahara, where the magnitude of these changes was huge –, with a special focus on the Tadrart Acacus and Messak region (SW Libya). Here, cultural and social trajectories go together with resilient mechanisms of adaptations. Archaeological evidence reveals that social strategies were pivotal in coping with environmental changes. Although it is certainly true that climate changes are in fact central elements in cultural trajectories, in the past as today, this is even truer for marginal ecosystems such as the changing landscapes of the Holocene central Sahara. However, the continuity of many cultural practices until historical times and even later shows how the Saharan tradition is indeed an extraordinary way of life that deserves specific attention.

Early globalization? Isotopic evidence of food practices in Prehistoric Italy

The cultural and social importance of food goes far beyond the mere necessity of nutrition, yet archaeologists have been slow to tackle issues of the sociality of food in prehistory. This is a great loss particularly as the economic transformations, which structured human diet took place in prehistory. One reason for lack of attention to this question has been limited methodologies for investigating not only what foods were produced but also exactly what foods people consumed.

The increasing application of biomolecular investigations of skeletal tissues offers an exceptionally valuable approach for directly assessing aspects of an individual’s life, including their diet, geographical origin as well as the climate they inhabited.

In the Central Mediterranean a number of important economic questions can be addressed through isotopic investigations: we can explore the balance between plant and animal sources of food in the diet of prehistoric people and how this change between the onset of the Neolithic (ca. 6000 BC) and the end of the Bronze Age (ca. 900 BC). We can assess the relative contribution of marine resources to diet the Central Mediterranean and, further, we can identify mode and tempo for the use of new foods.

This talk will present new isotopic data on a large set of sites from prehistoric Italy that span from the earliest phases of the Neolithic to the later Bronze Age. A pattern of great complexity emerges, showing profound differences between the northern and southern regions of the Peninsula, which can be associated with environmental aspects but mostly should be interpreted as different cultural practices across space and time.

Abstract:

The recent restoration of the Thousand-Armed Avalokiteshvara at Baodingshan in Dazu has generated a lively debate about the state of heritage conservation in modern China. This talk discusses this project from an ecological perspective that highlights the restorers’ sensitivity to the local climatic conditions and geological properties in preserving monumental cliff-side rock carvings. It also contextualizes the project as part of a long history of restoration in the region in which past restorers likewise pursued eco-compatibility in the materials and methods needed to repair cave temples for present and future visitors.
