Revolutionary archaeology in Cuba

The Revolution of 1959 brought forth changes in the mission, theoretical orientation, and organization of archaeology in Cuba and created a role for, and constraints on, the profession that are unique in the Western Hemisphere. This paper draws upon examples from substantive field and laboratory research to examine the methods and theoretical perspectives of Cuban archaeology since the Revolution, focusing on the period from 1962 until the collapse of the Soviet Union. Archaeological practice during the Revolutionary period in Cuba has reflected the aims of the Revolutionary government, the influence of Soviet archaeology, the legacy of pre-Revolutionary approaches in North American archaeology, and the Cuban sense ofpatria.     

Caddoan Area archaeology since 1990

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction.

Pressurised pastoralism in South Gobi, Mongolia: what is the role of drought?

The desert-steppe region of southern Mongolia is susceptible to drought and extreme winter weather ( dzud ) that in combination form Mongolia's worst natural hazard. Low precipitation and high climatic variability in this dryland environment impact the landscape and affect pastoralism, the dominant rural lifestyle. Using the Standardised Precipitation Index (SPI), this paper identifies drought occurrence in South Gobi Province, Mongolia. It then examines the relationship of drought with climate factors, interaction with vegetation (derived from Normalised Difference Vegetation Index - NDVI - data), and local human and livestock populations, and the dzuds of 1999–2001. Results show that drought is recurrent in the region, reaching extreme intensity most recently in 2005–2006. In contrast with the prevailing concept of drought impacting dzuds , the study did not find a connection between drought and dzud in South Gobi Province. Though repeated events, these natural hazards occur independently in the region. Climatic variables show increasing temperatures (>1°C), fluctuating precipitation patterns and a decline in vegetation cover. The principal long-term correlation of drought is with human population rather than natural factors, dzud or livestock numbers.
