Empire’s labor: the global army that supports U.S. wars

In a dramatic unveiling of the little-known world of contracted military logistics, Adam Moore examines the lives of the global army of laborers who support US overseas wars. Empire's Labor brings us the experience of the hundreds of thousands of men and women who perform jobs such as truck drivers and administrative assistants at bases located in warzones in the Middle East and Africa. He highlights the changes the US military has undergone since the Vietnam War, when the ratio of contractors to uniformed personnel was roughly 1:6. In Afghanistan it has been as high as 4:1. This growth in logistics contracting represents a fundamental change in how the US fights wars, with the military now dependent on a huge pool of contractors recruited from around the world. It also, Moore demonstrates, has social, economic, and political implications that extend well beyond the battlefields.

Focusing on workers from the Philippines and Bosnia, two major sources of "third country national" (TCN) military labor, Moore explains the rise of large-scale logistics outsourcing since the end of the Cold War; describes the networks, infrastructures, and practices that span the spaces through which people, information, and goods circulate; and reveals the experiences of foreign workers, from the hidden dynamics of labor activism on bases, to the economic and social impacts these jobs have on their families and the communities they hail from. Through his extensive fieldwork and interviews, Moore gives voice to the agency and aspirations of the many thousands of foreigners who labor for the US military.

On the connection between continental-scale land surface processes and the tropical climate in a coupled ocean-atmosphere-land system

An evaluation is presented of the impact on tropical climate of continental-scale perturbations given by different representations of land surface processes (LSPs) in a general circulation model that includes atmosphere-ocean interactions. One representation is a simple land scheme, which specifies climatological albedos and soil moisture availability. The other representation is the more comprehensive Simplified Simple Biosphere Model, which allows for interactive soil moisture and vegetation biophysical processes. The results demonstrate that such perturbations have strong impacts on the seasonal mean states and seasonal cycles of global precipitation, clouds, and surface air temperature. The impact is especially significant over the tropical Pacific Ocean. To explore the mechanisms for such impact, model experiments are performed with different LSP representations confined to selected continental-scale regions where strong interactions of climate-vegetation biophysical processes are present. The largest impact found over the tropical Pacific is mainly from perturbations in the tropical African continent where convective heating anomalies associated with perturbed surface heat fluxes trigger global teleconnections through equatorial wave dynamics. In the equatorial Pacific, the remote impacts of the convection anomalies are further enhanced by strong air-sea coupling between surface wind stress and upwelling, as well as by the effects of ocean memory. LSP perturbations over South America and Asia-Australia have much weaker global impacts. The results further suggest that correct representations of LSP, land use change, and associated changes in the deep convection over tropical Africa are crucial to reducing the uncertainty of future climate projections with global climate models under various climate change scenarios. © 2013 American Meteorological Society.
