We describe a preliminary survey of a relatively unknown part of the eastern Himalayas: northwestern Sichuan. This survey revealed that three phases of occupation are represented across the landscape. Large settlements with dense remains characterize the landscape during the Neolithic (3400–2000 cal b.c.). Following a hiatus in occupation, stone-cist graves characterize the region during the Bronze Age (1450–800 cal b.c.). The lack of settlement remains from this period indicates that mobile pastoralism increased in importance. Finally, between a.d. 500 and 1500, dense scatters of ceramics over a wide altitudinal range correspond to a fragmentation in Tibetan history, when local warlords established themselves in the region. While some changes in occupation and subsistence practices are linked to climate change, others relate to changes in political power. We argue that further survey work is needed to expand our understanding of past land use and the development of pastoralist practices. 相似文献

Environmentalists and environmental organizations in the USA have long identified population growth as a key threat to environmental sustainability at local and global scales. The neo‐Malthusian logics they invoke embed racialized images and categories in defining population “problems”, yet increasingly social justice language is invoked in population debates as a “solution” in the context of international development. This article explores the historical and contemporary characterizations of race as a central component of population–environment advocacy. It focuses on locations of race narratives in both the conceptualizations of population growth as an environmental problem, and family planning as a global solution. Through a critical analysis of the “population justice” framework, I argue that new discursive approaches attempt to reposition population work as socially just, while eliding critical analyses of race. 相似文献
