From Traditional Farming in Morocco to Early Urban Agroecology in Northern Mesopotamia: Combining Present-day Arable Weed Surveys and Crop Isotope Analysis to Reconstruct Past Agrosystems in (Semi-)arid Regions

ABSTRACT

We integrate functional weed ecology with crop stable carbon and nitrogen isotope analysis to assess their combined potential for inferring arable land management practices in (semi-)arid regions from archaeobotanical assemblages. Weed and GIS survey of 60 cereal and pulse fields in Morocco are combined with crop sampling for stable isotope analysis to frame assessment of agricultural labour intensity in terms of manuring, irrigation, tillage and hand-weeding. Under low management intensity weed variation primarily reflects geographical differences, whereas under high management intensity fields in disparate regions have similar weed flora. Manured and irrigated oasis barley fields are clearly discriminated from less intensively manured rain-fed barley terraces in southern Morocco; when fields in northern and southern Morocco are considered together, climatic differences are superimposed on the agronomic intensity gradient. Barley δ¹³C and δ¹⁵N values clearly distinguish among the Moroccan regimes. An integrated approach combines crop isotope values with weed ecological discrimination of low- and high-intensity regimes across multiple studies (in southern Morocco and southern Europe). Analysis of archaeobotanical samples from EBA Tell Brak, Syria suggests that this early city was sustained through extensive (low-intensity, large-scale) cereal farming.     

Core Use-Life Distributions in Lithic Assemblages as a Means for Reconstructing Behavioral Patterns

Artifacts with varying use-lives have different discard rates and hence are represented unequally among archaeological assemblages. As such, the ability to gauge the use-lives of artifacts is important for understanding the formation of archaeological assemblage variability. In lithic artifacts, use-life can be expressed as the extraction of utility, or work potential, from existing stone volume. Using experimental data and generalized linear modeling, this study develops models of artifact use-life on cores in the form of reduction intensity. We then apply these models to two archaeological case studies to (a) reconstruct the reduction intensities of archaeological cores and (b) investigate the survivorship curves of these archaeological cores across the reduction continuum using the Weibull function. Results indicate variation in core reduction and maintenance with respect to raw material properties and place use history and implicate evolutionary differences between Early Stone Age hominins and Holocene modern humans.     

“A Little Gravy in the Dish and Onions in a Tea Cup”: What Cookbooks Reveal About Material Culture

Six British colonial and Anglo-American cookbooks from the period 1770–1850 provide insights into the ways in which items of material culture often were used in the past. The multiple functions of many items suggest the need for critical reconsiderations of the functional typologies and status markers so heavily relied upon by historical archaeologists, as well as rethinking of gender associations for some items of material culture.     

The National Competition Policy: A Study of the Policy Process and Network

In his recent work on the Australian political system, Ian Marsh argues that interest groups and issues movements should be treated as 'potential partners and collaborators with government' (1995, p. 1). He suggests that the traditional two-party system with its inherent reliance on adversarial relations may need to mutate to cope with the demands which stakeholders are placing on the policy process and a changing political culture. This paper examines evidence that collaborative and cooperative modes of interaction are developing in Australia as a feature in the strategies used by both government and non-government players.
