    Energy and Climate Implications for Agricultural Nutrient Use Efficiency

    Energy and climate change are beginning to dominate the global political agenda and will drive policy formation that will shape the future of agriculture. Energy issues threaten national security and economic stability, as well as access to low-cost nutrient inputs for agriculture. Climate change has the potential to cause serious disruption to agricultural productivity. Paradoxically, nutrient use in agriculture to increase crop yields has the potential to negatively impact climate. This chapter will discuss recent and future energy and climate trends, the relationships between agricultural nutrient use efficiency and biofuels, and how global land limitations will shape agriculture in the future. Comparative gross energy yield and nitrogen use efficiency for ethanol production from crop residue, switchgrass, grain sorghum, sweet sorghum, and corn grain is presented, showing small differences in nitrogen use efficiency, but large differences in gross energy yields. In addition to considering the need to increase crop productivity to meet the demands of a growing population and bioenergy, agricultural nutrient use efficiency must be reconsidered with respect to the important energy and climate challenges shaping agriculture today

    The tragedy of liberal diplomacy: democratization, intervention, statebuilding (part I)

    Since the end of the Cold War, democracy promotion, intervention and statebuilding have once again been explicit features of American foreign policy. Current assessments of this return, however, overlook both their longer term history and their roots in liberal (and not just American) ideology. The contradictions and dynamics entailed in the liberal philosophy of history have already played themselves out once before, in the modernization theories and policies of the early Cold War period. Despite their academic and political failures at the time, the same assumptions now underpin democracy promotion in the post-Cold War period and show signs of the same dynamics of failure. In this two part essay, I argue that the repetition of such counterproductive policies constitutes a recurring ‘tragedy of liberal diplomacy’ in which the shaping of US foreign policy by assumptions deeply rooted in the liberal philosophy of history plays a central part in producing the very enemies that policy is designed to confront and transform
