This issue of Human Ecologyis devoted to studies of household organization, originally presented at an invited session of the American Anthropological Association annual meetings in New Orleans in 1990. These papers share an empirical orientation and an interest in demographic processes and economic change, particularly in rural and non-Western societies, including !Kung foragers and Herero agro-pastoralists of Botswana, Ariaal and Rendille pastoralists of Kenya, Gainj horticulturalists of highland New Guinea, and a Euro-Caribbean populaiton of St. Barthélemy, West Indies. These papers demonstrate both the vitality of household studies and the utility of empirical approaches in understanding household formation, continuity, and adaptation to social, economic, and political change.

The “Boserup hypothesis” contends that land-intensive systems of agriculture will be adopted only when high population density precludes the use of land-extensive methods. In the Kerayan District of East Kalimantan (Indonesia) the Lun Dayeh practice permanent-field rice cultivation despite very low human densities. An examination of the relative labor efficiencies of shifting and permanent-field agriculture in the Kerayan, as well as of local environmental and historical variables, explains why this “anomalous” situation exists. It is argued that since relative success in production of rice by shifting- and permanent-field irrigated methods depends on many natural and social conditions other than levels of population density, the “environment-free” Boserup hypothesis cannot adequately explain or predict the occurrence of particular forms of rice agriculture.

Whaling remains one of the most contentious issues in global conservation. In South Korea, where commercial and subsistence whaling are both illegal, domestic sales of cetacean products such as skin, blubber and red meat are allowed if they are accidently caught. However, environmental groups have claimed that the high price of meat may be acting as an incentive for illegal hunting and ‘deliberate by-catch’ where whales are intentionally killed or left to die by fishermen when they become trapped in their nets. In this paper we investigate the issue of deliberate by-catch and illegal hunting of the protected Minke J-stock population in Korean waters using grounded theory, an approach that allows theories and understanding to emerge from the analysis of both qualitative and quantitative data. Our research suggests that deliberate by-catch is almost certainly taking place but that illegal hunting and/or illegal importation from Japan may be far more significant sources of Minke whale meat. We discuss possible measures to reduce incentives for deliberate by-catch and illegal hunting such as the introduction of mandatory reporting of quantities supplied and consumed in restaurants and a tax on meat sales at auction. More generally, our research illustrates how the analysis of price movements can shed light on the scale of illegal wildlife trade and how a combination of both qualitative and quantitative methodologies can provide understanding of a complex, multifaceted conservation issue.

In 2007 Swiss Federal legislation introduced Regional Nature Parks (RNPs). In this paper I treat the landscape as an object of political-legal regulation and focus on the governance of its uses. I use the constitutionality framework to support our analysis. Constitutionality refers to a form of institution building that stresses bottom-up natural resource management initiatives. Through a detailed case study I show that the interests of landscape users are not equally well protected by law. The success of the new parks model depends on a subtle balance between local self-organization and top-down control. The interests of the weakest actors, i.e., landscape viewers, can be supported only through strong backing at higher levels of government.

Establishing private property in land through registration and titling has been promoted in developing countries due to the anticipated benefits of private ownership in access to credit, productivity enhancing investments, and productivity gains. Evidence of such benefits is limited, however. In this paper, we examine a related question: What is the impact of privatization on cooperation in farm labor? Data collected in 2005 from Samburu District in Kenya is analyzed, comparing one community where land has been privatized to a second where land is communally held in a group ranch. It is hypothesized that households with title deeds are less likely to cooperate in farm labor than households without deeds. The hypothesis was confirmed, as the odds of cooperating in communal farm labor are 93.0% lower for households with deeds compared to those without. This effect has negative implications for collective action efforts in Siambu.

We determined stunting, wasting, and obesity frequencies in a total 1092 2-to-12 year old Baka Pygmy children from anthropometric and health data gathered in 34 villages in the Djoum-Mintom region in southeastern Cameroon in four health campaigns in 2010 and 2017–9. We compare these to the WHO Child Growth Standards, Amazonian Tsiname growth references for inter-population comparisons and the study population itself. Population-specific growth charts were constructed using GAMLSS modelling. Our results show that Baka children have one of the highest global rates of stunting relative to the WHO child growth standard with 57.8% for 2-to-12 year olds and 64% and 73% for 2-to-4 year old girls and boys, respectively. Frequencies of wasting, overweight, and low BMI were low at 3.4%, 4.6% and 4.3%, respectively, for 2-to-12 year olds. Underweight was at 25.5%, in the upper range for sub-Saharan Africa. Edemas indicated rare severe malnutrition (0.3%). Uncertainties in age estimation had dramatic effects on the reliability of estimated individual z-scores but distributions of z-scores were robust at a population level. In the context of the recent evidence for genetic adaptation of the Pygmies’ small stature to the tropical forest environment we argue that WHO child standards for weight and BMI are applicable. However, standards for height are clearly not adequate for Pygmy people. To achieve UN Sustainable Development Goals, we recommend that Pygmy specific growth standards are developed for the various, genetically differing Pygmy tribes.

The Mountain Pine Beetle (MPB) infestation in Colorado and Wyoming impacts federal and state forest managers, the recreation and tourism industry, ecosystem services, and the general sustainability of livelihoods in proximity to forested areas. Using qualitative analyses, this paper investigates whether a linkage exists between individuals’ value orientations and their attitudes toward forest management in relation to MPB infestations. Data were obtained in 2011 from three open-ended questions in a mail survey of residents in Colorado and Wyoming. Our qualitative analysis revealed four value orientation types: 1) biocentric, 2) anthropocentric, 3) spiritual/therapeutic, and 4) pluralist. Additionally, respondents were generally supportive of forest management practices and the majority had a “do what you need to save the forest” attitude. A linkage between value orientations toward the national forest and management practices was identified. Research and management implications are discussed.
