For 21st century warfare, space is the unquestioned new high ground for military operations. The United States (U.S.) has relied on satellites for significant support to military operations and activities since Desert Storm in 1991. Indeed, the U.S. enjoys an asymmetric advantage in modern warfare utilizing our space capabilities. States with interests hostile to the U.S. believe that the significant dependence on space assets by the U.S. military could become its “Achilles heel” in future combat operations. What are the legal and policy bases for the U.S. to respond to threats to space systems that provide support to our military forces? Should the U.S. rely on space arms control initiatives to ensure security in space? This Viewpoint analyzes the international space law regime and U.S. National Space Policy framework applicable to the conduct of military space operations and activities, including the use of force in space to protect and defend our satellite networks as well as our military forces. 相似文献

It is commonly agreed that Africa has become increasingly marginalised within the current global economy. However, there are few existing attempts to identify the precise contours of this marginalisation or to explicate the dynamics giving it a precise shape. Against the background of a discussion of theoretical entry points to this problem, as well as of some of its broad quantitative dimensions, this article attempts to develop working hypotheses focused on the marginalisation/restructuring of African export crop agriculture. 相似文献

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
