Studies of accumulation by dispossession in the Global South tend to focus on individual sectors, for example, large‐scale agriculture or nature conservation. Yet smallholder farmers and pastoralists are affected by multiple processes of land alienation. Drawing on the case of Tanzania, we illustrate the analytical purchase of a comprehensive examination of dynamics of land alienation across multiple sectors. To begin with, processes of land alienation through investments in agriculture, mining, conservation, and tourism dovetail with a growing social differentiation and class formation. These dynamics generate unequal patterns of land deprivation and accumulation that evolve in a context of continued land dependency for the vast majority of the rural population. Consequently, land alienation engenders responses by individuals and communities seeking to maintain control over their means of production. These responses include migration, land tenure formalization, and land transactions, that propagate across multiple localities and scales, interlocking with and further reinforcing the effects of land alienation. Various localized processes of primitive accumulation contribute to a scramble for land in the aggregate, providing justifications for policies that further drive land alienation.  相似文献

This paper assesses how retail firms in Ghana pursue positioning activities. Overt observations, face-to-face interviews with staff, managers and mall intercept methods provide an insight into the positioning strategies of firms in the retail sector. We adopt an empirically based and generic consumer-derived typology of positioning strategies to obtain the results. The findings revealed that the dominant strategies are “service,” “value for money,” “attractiveness,” “reliability,” “top of the range,” selectivity, and “brand name.” The emphasis placed on each of these positioning strategies varies from firm to firm.  相似文献

Since attainment of independence, almost every country in East and Southern Africa has introduced some kind of land reform aimed at reconciling indigenous land tenure practices and those introduced by colonial regimes. The reforms have centred on modification of tenurial rules on access, ownership, administration and transfer of land rights coupled with land redistribution and/or restitution in some countries. With the exception of a few countries, such as Botswana, land reforms have largely remained on statute books with little to show on the ground. The paper gives an overview of land reforms in East and Southern Africa, taking Botswana as a case study. It notes that although Botswana has largely been successful in implementing land reforms, it is currently experiencing land tenure problems, especially in peri-urban settlements and inner city low-income areas, despite government's enhanced control over local land administrative structures. The paper ends with suggestions on how to contain the current problems.  相似文献
