It has long been thought that the only means by which the American Southwest's extensive pinyon-juniper woodlands, with their inherently low primary productivity, could have supported indigenous populations during prehispanic times was with the transformative consequences associated with the widespread cultivation of low-moisture-intolerant domesticated plants, principally maize (Zea mays L.). In this paper we present an alternative to this orthodox view which posits that anthropogenic fire was a vegetation-community management technology that was used to create disturbance patches and to propagate abundant, edible seed-rich ruderals in them. This perspective allows us, as well, to introduce and illustrate the interpretive possibilities of a conceptual scheme that focuses on three resource production types—cultivated wild plants, gathered wild plants, and domesticated plants—with multi-contextual macrobotanical data from a partially burned and rapidly abandoned multi-room settlement (occupied between AD 1070–1080) located south of the Grand Canyon in northern Arizona. By integrating these data with previous archaeobotanical, pollen, and sedimentary micro-charcoal studies, we propose that the systematic cultivation of wild plants in pyrogenic resource patches was a sustainable practice that enhanced food-supply security by insulating populations from the effects of short-term environmental variability and long-term climate change that challenge maize farmers. Importantly, these investigations indicate that low-intensity burning did not involve widespread deforestation, as some models of Holocene climate change suggest, and that prehistoric depopulation and modern fire suppression have altered fundamentally the composition and economic potential of contemporary pinyon-juniper ecosystems.
The archaeological site of Caesarea Maritima in modern-day Israel was an important coastal town in the Early Islamic period (c. 636–1100 CE). In this article, I analyze 15 samples of carbonized wood and non-wood macrobotanical remains recovered from two residential neighborhoods to investigate the production and consumption of agricultural plant products. The identified crop and wood taxa are typical for the Mediterranean coast. Wild seeds point to crop cultivation in the vicinity of the site. Plant remains were collected from discrete contexts and are interpreted with associated features and artifacts, revealing cereal processing debris across a series of rooms in a former warehouse. Such a socioeconomic shift in this building, from a storage area to a crop processing space, is detectable by combining this intrasite analysis with the diachronic research previously conducted at the site.
This article combines historical and archaeological evidence to investigate the role arboriculture played in the agricultural economy in the southern Levant as centers of production moved away from rural agricultural estates and focused instead on urban centers. Integrating this evidence with archaeobotanical data from Early Islamic deposits at the archaeological site of Ashkelon, located on the southern Mediterranean coast of modern-day Israel, I conclude that people specialized in arboriculture as a means to supply the needs of both subsistence and craft economies in this city, encapsulating the intensification of agricultural production in this period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
