The rights to prior consultation and compensation have been established within the framework of international indigenous peoples’ rights. However, in practice these processes have often gone hand in hand with adverse social consequences for local populations, such as the exacerbation of conflicts, the division of communities and the weakening of indigenous organizations. These phenomena have received little attention, despite their great relevance for these populations. This article sheds light on the use by the Bolivian state and extraction corporations of exclusionary participation and negotiation processes, on the one hand, and ‘carrot‐and‐stick’ techniques on the other, which have together accounted for negative social impacts on the ground. The article is based on recently conducted field research, focus group discussions and semi‐structured interviews in Guaraní communities in Bolivia. The findings extend the existing literature by providing a fine‐grained and systematic analysis of divisive undertakings and their sociocultural and sociopolitical consequences in neo‐extractivist Bolivia. The broader implications of the study add to academic debates about participation in development, about ‘divide‐and‐rule’ tactics and about the practice of indigenous peoples’ rights.  相似文献

A long‐standing debate in archaeology concerns the sources of technological diversification among prehistoric hunter‐gatherers. This includes the study of the emergence and spread of pressure blade technology in Northern Europe during the Early Holocene. Until now, there has been little technological study of lithic collections from the East Baltic region, and our knowledge of the development and spread of this technology in the area is inadequate. This article presents for the first time a technological analysis of lithic assemblages from seven Early and Middle Mesolithic sites in the territory of present‐day Latvia, offering new possibilities for discussing pressure blade technology and research objectives connected with it. Furthermore, variation in elements of this technology is explored in relation to raw‐material characteristics through experimental flint knapping. Finally, the factors influencing diversity in craft traditions, as well as large‐scale communication and shifting spheres of interaction within Northern Europe during the Mesolithic, are discussed.  相似文献

Genetic studies of Neolithic groups in central Europe have provided insights into the demographic processes that have occurred during the initial transition to agriculture as well as in later Neolithic contexts. While distinct genetic patterns between indigenous hunter-gatherers and Neolithic farmers in Europe have been observed, it is still under discussion how the genetic diversity changed during the 5,000-year span of the Neolithic period. In order to investigate genetic patterns after the earliest farming communities, we carried out an ancient mitochondrial DNA (mtDNA) analysis of 34 individuals from Wittmar, Germany representing three different Neolithic farming groups (ca. 5,200–4,300 cal bc) including Rössen societies. Ancient DNA analysis was successful for six individuals associated with the Middle Neolithic Rössen and observed haplotypes were assigned to mtDNA haplogroups H5, HV0, U5, and K. Our results offer perspectives on the genetic composition of individuals associated with the Rössen culture at Wittmar and permit insights into genetic landscapes in central Europe at a time when regional groups first emerged during the Middle Neolithic.  相似文献
