Multiscale Factors Affecting Human Attitudes toward Snow Leopards and Wolves

The threat posed by large carnivores to livestock and humans makes peaceful coexistence between them difficult. Effective implementation of conservation laws and policies depends on the attitudes of local residents toward the target species. There are many known correlates of human attitudes toward carnivores, but they have only been assessed at the scale of the individual. Because human societies are organized hierarchically, attitudes are presumably influenced by different factors at different scales of social organization, but this scale dependence has not been examined. We used structured interview surveys to quantitatively assess the attitudes of a Buddhist pastoral community toward snow leopards (Panthera uncia) and wolves (Canis lupus). We interviewed 381 individuals from 24 villages within 6 study sites across the high‐elevation Spiti Valley in the Indian Trans‐Himalaya. We gathered information on key explanatory variables that together captured variation in individual and village‐level socioeconomic factors. We used hierarchical linear models to examine how the effect of these factors on human attitudes changed with the scale of analysis from the individual to the community. Factors significant at the individual level were gender, education, and age of the respondent (for wolves and snow leopards), number of income sources in the family (wolves), agricultural production, and large‐bodied livestock holdings (snow leopards). At the community level, the significant factors included the number of smaller‐bodied herded livestock killed by wolves and mean agricultural production (wolves) and village size and large livestock holdings (snow leopards). Our results show that scaling up from the individual to higher levels of social organization can highlight important factors that influence attitudes of people toward wildlife and toward formal conservation efforts in general. Such scale‐specific information can help managers apply conservation measures at appropriate scales. Our results reiterate the need for conflict management programs to be multipronged.

Importance of the National Petroleum Reserve–Alaska for Aquatic Birds

We used data from aerial surveys (1992–2010) of >100,000 km² and ground surveys (1998–2004) of >150 km² to estimate the density and abundance of birds on the North Slope of Alaska (U.S.A.). In the ground surveys, we used double sampling to estimate detection ratios. We used the aerial survey data to compare densities of birds and Arctic fox (Vulpes lagopus), the major nest predator of birds, on the North Slope, in Prudhoe Bay, and in nearby areas. We partitioned the Prudhoe Bay oil field into 2 × 2 km plots and determined the relation between density of aquatic birds and density of roads, buildings, and other infrastructure in these plots. Abundance and density (birds per square kilometer) of 3 groups of aquatic birds—waterfowl, loons, and grebes; shorebirds; and gulls, terns, and jaegers—were highest in the National Petroleum Reserve–Alaska (NPRA) and lowest in the Arctic National Wildlife Refuge. Six other major wetlands occur in the Arctic regions of Canada and Russia, but the largest population of aquatic birds was in the NPRA. Aquatic birds were concentrated in the northern part of the NPRA. For example, an area that covered 18% of the NPRA included 53% of its aquatic birds. The aerial surveys showed that bird density was not lower and fox density was not higher in Prudhoe Bay than in surrounding areas. Density of infrastructure did not significantly affect bird density for any group of species. Our results establish that the NPRA is one of the most important areas for aquatic birds in the Arctic. Our results and those of others also indicate that oil production, as practiced in Prudhoe Bay, does not necessarily lead to substantial declines in bird density or productivity in or near the developed areas.

Application of the Anthropogenic Allee Effect Model to Trophy Hunting as a Conservation Tool

Trophy hunting can provide economic incentives to conserve wild species, but it can also involve risk when rare species are hunted. The anthropogenic Allee effect (AAE) is a conceptual model that seeks to explain how rarity may spread the seeds of further endangerment. The AAE model has increasingly been invoked in the context of trophy hunting, increasing concerns that such hunting may undermine rather than enhance conservation efforts. We question the appropriateness of uncritically applying the AAE model to trophy hunting for 4 reasons. First, the AAE assumes an open‐access resource, which is a poor characterization of most trophy‐hunting programs and obscures the potential for state, communal, or private‐property use rights to generate positive incentives for conservation. Second, study results that show the price of hunting increases as the rarity of the animal increases are insufficient to indicate the presence of AAE. Third, AAE ignores the existence of biological and behavioral factors operating in most trophy‐hunting contexts that tend to regulate the effect of hunting. We argue that site‐specific data, rather than aggregated hunting statistics, are required to demonstrate that patterns of unsustainable exploitation can be well explained by an AAE model. Instead, we suggest that conservation managers seeking to investigate and identify constraints that limit the potential conservation role of trophy hunting, should focus on the critical governance characteristics that shape the potential conservation role of trophy hunting, such as corruption, insecure property rights, and inadequate sharing of benefits with local people.

Effect of Information Availability on Assessment and Designation of Species at Risk

Abstract: Information required to evaluate the extent to which species are at risk of extinction is usually limited and characterized as highly uncertain. In this context, we define information availability as the presence or absence of information used to determine the value of an ecological variable. We examined which of three hypothetical approaches best matched how levels of risk are assigned to species: (1) precautionary approach in which analysts designate levels of risk regardless of the amount of information available, (2) worst‐case approach in which analysts assign the maximum level of risk possible from the criteria, and (3) insurance approach in which analysts assign poorly known species to a high‐risk category when little information is available. We used the quantitative assessment criteria of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as a case study. We created a binary (0/1) matrix of all 2.4192 × 10⁷ logical combinations of available information for the 14 ecological variables included in the quantitative criteria. We processed each combination of information availability represented in the matrix with a computer algorithm designed to emulate COSEWIC decision‐making rules. Low information availability was associated with a relatively high frequency of not being able to assign a candidate taxon to a risk category, which does not follow the precautionary principle. Information availability and the level of risk assigned to species were directly related, which is associated with the worst‐case approach, and counter to the insurance approach. Our results suggest that information availability can have a major effect on the level of risk assigned to a species. We recommend a conscious determination of whether such effects are desired, and we recommend the development of methods to explicitly characterize and incorporate information availability and other sources of uncertainty in decision‐making processes.     

Permanent Sovereignty Over Natural Resources

In the 1960s and 1970s, the principle of permanent sovereignty over natural resources was vigorously expressed by oil-producing developing countries, through a series of measures to increase revenue from, ownership of, and effective control over the petroleum sector. Such recent significant developments as OPEC's crude oil price reduction, favorable tax treatment of transnational oil companies in the industrialized countries, the entry of the World Bank onto the international pertroleum scene and increasing competition among developing countries for scarce company exploration funds have combined to create a new, more difficult environment, in which further progress toward full sovereignty over petroleum resources will be achieved more by countries' own efforts, and less in the context of host country-oil company negotiations. Le principe de souveraineté permanente en matière de ressources naturelles a été exprimé avec vigueur par les pays producteurs de pétrole en voie de développement au cours des decenics de 1960 et 1970 par une série de mesures visant à augmenter les revenus, les droits de proprieté et le contrôle effectif afférents au secteur pétrolier. Des éléments nouveux importants, tels que la baisse des prix du brut OPEP, les structures de l'ompót qui favorissent les sociétés pétrolieres transnationales des pays industrialisés, l'entrée en scène de la Banque mondiale en ce qui concerne le pétrole sur le plan international, et la concurrence croissante des pays en voie de développement pour les rares financements d'exploration par les sociétés privécs ont contribué à la création d'un milieu nouveau et plus ardu au sein duquel un nouveau progrès vers une souveraineté totale en matière de ressources pétrolieres se fera de plus en plus par les initiatives propres des pays et de moins en moins dans le contexte de négociacions entre les pays et les sociétés pétrolieres. En las décadas del 60 y 70, el principio de soberanía permanente sobre recursos naturales fue expresado vigorosamente por los países en desarrollo productores de petróleo, a través de diversas medidas con el objeto de aumentos el ingreso del sector petrolero y reafirmar el control y propriedad sobre éste. Nuevos hechos tales como la reducción del prccios acordados por la OPEP, impuestos favorables para las compañías transnacionales, la participatión del Banco Mundial en el sector del petróleo y la creciente competencia entre países en desarrollo por escasos fondos para exploración petrolera han creado un ambiente diffícil en el que la total soberanía sobre los recursos petroleros se obtendrán más por esfuerzo propio de los países y menos dentro del contexto de negociaciones entre país y las compañías de petróleo.     

Food Security Reserve Policy in Ethiopia: A Case Study of Experience and Implications

Food security reserve policy in Ethiopia since 1982 is reviewed in the light of the limited progress made elsewhere in Africa in establishing and maintaining such reserves. While the reserve played some role in dealing with the crisis of 1987/8, donor confidence was eroded by unauthorised drawings from the reserve and other factors. In 1992, the Ethiopian Food Security Reserve Authority was established to provide a system of management more acceptable to donors. This had led to donor pledges to replenish the reserve, though it remains well below the target level. Despite increased government commitment of funds, donor confidence remains fragile and the reserve remains dependent on donor support. The place of the reserve in national food security policy is not yet fully defined. Conclusions are drawn for food security reserve policy in Ethiopia and elsewhere in Africa.
