Foreign investment in agricultural land acquisition in sub-Saharan Africa has been viewed primarily as driven by a set of linked ‘crises’: in financial capital markets, in security of energy and food supply, and in global environmental governance. This paper argues that a focus on the ‘buyers’ of land risks overlooking the dynamics that operate on the side of the land ‘sellers’. Accordingly, the first part of the paper argues that it is important to view the current ‘land grab’ as the latest stage in a longer historical process of competition for control of land and other natural resources by different ‘domestic’ economic and political actors within African countries. While such struggles are often characterised as the ‘state versus the peasantry’, with the state acting on behalf of ‘urban elites’, the paper argues that processes of accumulation and associated enclosure of natural resources need to be examined more critically in specific contexts if the role and impact of foreign capital investment are to be understood. The second part of the paper seeks to identify the ways in which questions of scale (in the sense of greater capital intensity) can be considered to be constraints to the development of African agriculture. Particularly, it considers the extent to which the production models most frequently mentioned in connection with foreign investment (large-scale mechanised farms and small-scale outgrower contract farming) respond to current productivity constraints. The paper argues that current debates about foreign investment in agricultural land underplay the importance of water resources needed to overcome production risks associated with irregular rainfall. Bringing the water dimension of land deals more clearly into focus is necessary if the scope for positive and negative impacts of new investment on existing land users is to be fully understood. The paper concludes by considering the implications of such challenges in the current context of foreign investment in agriculture in Africa.  相似文献

Ties between India and South Africa have grown rapidly over the past few years. But despite close collaboration on a range of issues and growing trade and investment ties, the relationship is a long way from reaching its full potential and there are still areas of difference between the countries. Philip Alves examines how the relationship has evolved historically, particularly since 1994, both politically and economically, and where it might be going.  相似文献

Whether or not an unfettered market is the best solution to Africa's problems, the public service is both the subject and the object of reform. It is an arena of policy change and adjustment in economic management, as well as the locus of struggle over principles and patterns of administrative practice. Below we take empirical stock of the patterns and progress made in public service reform in Africa, a process characterized by cost containment and retrenchment. Then we examine what is entailed in a qualitatively different public service that well serves a liberal economy, concluding with observations on whether and how that might happen in Africa.  相似文献

This article reviews proposals regarding the recent food crisis in the context of a broader, threshold debate on the future of agriculture and food security. While the MDGs have focused on eradicating extreme poverty and hunger, the food crisis pushed the hungry over the one billion mark. There is thus a renewed focus on agricultural development, which pivots on the salience of industrial agriculture (as a supply source) in addressing food security. The World Bank's new 'agriculture for development' initiative seeks to improve small-farmer productivity with new inputs, and their incorporation into global markets via value-chains originating in industrial agriculture. An alternative claim, originating in 'food sovereignty' politics, demanding small-farmer rights to develop bio-regionally specific agro-ecological methods and provision for local, rather than global, markets, resonates in the IAASTD report, which implies agribusiness as usual 'is no longer an option'. The basic divide is over whether agriculture is a servant of economic growth, or should be developed as a foundational source of social and ecological sustainability. We review and compare these different paradigmatic approaches to food security, and their political and ecological implications.  相似文献
