"This article provides a set of codes that rate the starvation and famine experiences of societies in the Standard Cross-Cultural Sample. The codes are used to test several theoretical generalizations regarding the underlying causes of famine." Results indicate that seasonal starvation and direct entitlements are the strongest predictors of famine.

The article discusses the importance of incorporating local knowledge and strategies into sustainable climate change adaptation. The authors examined 90 societies from the ethnographic record to document the coping mechanisms and contingency plans used by societies around the world in response to natural hazards. They classified coping mechanisms into four types: technological, subsistence, economic, and religious. The study finds that most societies employ multiple types of coping mechanisms and that technological coping mechanisms are most common in response to fast-onset hazards, while religious coping mechanisms are most common in response to slow-onset hazards. The study also finds that religious and nonreligious coping strategies are not mutually exclusive and are often used in conjunction with each other.

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

Using a cross-cultural sample of 91 societies, this paper draws on ecological theory to test if unpredictable environments will favor subsistence diversification. The general hypothesis is that societies with high climate unpredictability and resource stress would exhibit more subsistence diversity than societies in more stable climates. The authors examined four environmental and resource stress variables while controlling for temperature variance, subsistence activity, and phylogeny. Support was found for 2 of the 4 variables--chronic scarcity and environmental instability. In the discussion they suggest that more commonly observed events (e.g. annual hunger and climate unpredictability) may give people more motivation to change subsistence than rarer events (e.g. natural hazards and famine).

In this pilot study, the authors investigate the relationships between both subsistence types and environmental conditions, and various coping mechanisms for drought in 35 societies in Africa. Using Canonical Correspondence Analysis (CCA), they find subsistence strategies to have a more significant correlation with the distribution of coping strategies for drought than environmental conditions.

This study seeks to investigate the little-understood intermediate region between farming and foraging subsistence strategies. The authors seek to evaluate the extent to which such "middle-ground" subsistence methods actually exist, whether there is any geographical patterning to them, and if different crop assemblages/dependencies make middle-ground subsistence strategies more or less likely. They find that agro-pastoral, cereal-based societies in Africa and Eurasia are more likely to be dependent on farming (defined here as including both cultivation and animal husbandry), whereas societies in North America and those reliant on root crops and arboriculture in the wet tropics incorporate both farming and foraging. They conclude that there is likely more of a "middle-ground" between foraging and farming than has typically been allowed for in the literature.

This study tests four hypotheses that propose potential environmental and social predictors of toolkit size and complexity among hunter-gatherers. Hypotheses predicting relationships between population size, residential mobility, type of food resources and toolkit structure are not supported. Risk of resource failure is the only variable that is significantly associated with toolkit structure.

In this article, the authors seek to determine cross-culturally valid predictors of dominant types of human subsistence around the world. They did this by formulating multiple models that incorporate different combinations of environmental, geographic, and social factors. These models were then used to test various hypotheses posed throughout the anthropological literature surrounding factors that determine dominant subsistence strategies.

This article hypothesizes that ritual ecstasy was selected for as a way for hunter-gatherers to cope with resource uncertainty by unifying separate groups. Results support this hypothesis and suggest a relationship between resource stress and deities as well as dependence on animals and presence of zoomorphic deities.

In this paper, the authors analyzed data on 20 hunter-gatherer groups in order to understand the factors that influence the diversity and elaborateness of their tool assemblages. They used data collected by a variety of ethnographers to draw inferences about the complexity of implement assemblages and how it is affected by ecological constraints, modes of resource procurement, group movement, and population size. Regression analysis showed that the two strongest predictors of implement complexity were growth season (GS) (as a proxy for risk) and the number of annual residential moves (NMV). With the understanding that NMV and GS are likely not independent, the authors created addition and interaction models to understand how these variables may work in tandem to influence implement diversity and elaborateness. The results show that a shorter growing season (higher risk) and a lower number of moves are correlated with greater implement complexity. This analysis also divided the hunter-gatherers into two subgroups: a subgroup characterized by higher diversity of complex implements and more elaborate individual implements than predicted by the model, and a subgroup characterized by lower diversity and less elaborateness than predicted. These subgroups were found to correspond with the distinction between foragers (groups that move more-or-less as a unit while gathering) and collectors (groups that gather (logistically from a more-or-less fixed settlement), with the higher diversity subgroup being made up mostly of collectors and the lower diversity subgroup being made up mostly of foragers. Finally, the authors suggest that under conditions where population growth leads to increased density, foraging strategies will tend to shift to collector strategies in conjunction with increased elaborateness of implements to exploit resources with greater intensity.
