A water-management regionalization and determination of marginal cost estimates of water resources over the next three decades (to about 2000) outlines a set of priorities for the construction of dams and interbasin diversion projects. The predicted water requirements are based on the assumption that irrigation needs will increase at a moderate rate (30 million hectares by the end of the forecast period). The resulting marginal cost estimates are expected to affect long-term plans for the location of water-intensive activities (irrigation, water transport, thermal power generation, chemicals, pulp and paper) for which water costs may represent 40 to 50 percent of the total cost difference between alternate locations.  相似文献

This article illustrates how the Yamal-Nenets, a group of reindeer pastoralists in West Siberia, perceive a series of recent natural disasters to be connected to one another through a conspiracy – i.e. caused by the agency of malevolent human forces which are beyond the pastoralists’ control. Recent fieldwork during the peak of the global Covid-19 epidemic served as a trigger for this observation. Their self-confidence in the robustness of their lifestyle and their embeddedness within their natural environment is so strong that Yamal-Nenets nomads believe only evil forces – not nature – can stop them from being mobile. Alongside Covid-19, they interpret the severe consequences of natural disasters, such as iced pastures, related reindeer starvation and the outbreak of anthrax as man-made attempts to reduce the number of people and animals in the tundra. The blame they place on humans for these disasters takes place in the context of hitherto unseen gas industry developments in the area. Such interpretations may become a general pattern for changing perceptions of the world by remote indigenous populations when deprived of their once customary shamanic dialogue with the spirits.  相似文献

The threat of global warming has attracted considerable attention from policy makers around the world. We analyse public support for environmental protection and the main drivers of support in Australia and cross-nationally using survey data from the International Social Survey and the Australian Survey of Social Attitudes. Support is measured as a series of trade-off questions based on willingness to pay extra taxes or prices, or accept cuts to one's standard of living to protect the environment. Willingness to pay more for environmental protection has decreased across a range of countries from 1993 to 2000 with the ‘routinisation’ of ‘the environment’ as a political issue. Risk perceptions regarding the dangers of global warming, having a tertiary education and holding post-materialist value orientations all increase the willingness to pay for environmental protection. In Australia, environmental support is still divided along partisan lines and global warming was as an important issue in the 2007 federal election.  相似文献

The Zhokhov site is one of the northern most archaeological sites in the world and a very ancient vestige of occupation of high latitudes by people, indicating that this territory was settled as early as about 8000 years ago. Investigation of the site began in 1989–1990 and then continued in 2000–2005. Here we consider the taphonomy, spatial distribution, species and age- and sex-related composition of the faunal remains from the Zhokhov site. These data allow conclusions regarding the subsistence strategy practiced by Zhokhov inhabitants, including the hunting tactics. This was a peculiar adaptation model based on reindeer and polar bear hunting in a 2:1 ratio. Reindeer hunting was all-seasonal, whereas polar bears were hunted mostly in winters at their dens. Mortality data for reindeer and polar bears depict the yearly subsistence cycle. The Zhokhov site is found to be a base camp occupied year-round with modest summer activities, while wintertime is characterised by intense polar bear hunting. Most reindeer were hunted in the fall. Subsistence strategy of the Zhokhov hunters was largely facilitated by the fact that at the time of occupation Zhokhov Island was still part of the coastal Siberian plain margin.  相似文献
