Unformatted text preview: pson_GlobalFoodInsecurity_Jun12.pdf) Meanwhile, the political dimensions of “food insecurity” go well beyond our compassion for people in the poorest countries who are most vulnerable to famine and malnutrition. Even during the remainder of this decade, we face a transition from localized food shortages and insecurities toward a more pervasive environment of global “food shocks” that have serious political consequences even for the richer world. 3 The combined effects of population trends, climate changes, water shortages, soil erosion or contamination, increased meat consumption, fisheries depletion, major livestock epidemics, or serious crop failures in overlapping and cascading ripple effects will strain already-vulnerable economies and political systems. Sudden price increases or shortages could prompt volatile popular reactions, especially if citizens even in “well-fed” locations lose trust in markets and governments to assure their access to adequate food supplies. 12 | P a g e Inland Waterways Negative BDL No Solvency – Congestion [___] [___] Can’t reduce road congestion John Frittelli, Spet in Transportation Policy, 2011 (Can Marine Highways Deliver? January 14, 2011 http://assets.opencrs.com/rpts/R41590_20110114.pdf) In addition, a significant portion of domestic truck freight is carried in truck trailers rather than in containers that can be detached from their chassis. Barge services can carry truck trailers, but doing so is relatively inefficient, as trailers, unlike containers, cannot be stacked. These factors severely limit the potential universe of truck traffic that marine highways could divert from the highways. International shipments account for less than one-tenth of total truck tonnage. The vast majority of the trucks contributing to highway congestion are serving routes or carrying products for which short-sea transport is not a viable alternative, or else are not designed to haul detachable ocean shipping containers. [___] Can’t solve delays – competing boats make it too difficult Brad Walker, Wetlands & Floodplain Director at Missouri Coalition for the Environment, 2010 (Big Price – Little Benefit, Prepared by the Nicollet Island Coalition February 2010 http://www.iwla.org/index.php?ht=a/GetDocumentAction/i/2079) Additionally, a critical element of delay estimation is how m uch of the delay at a lock will be directly attributable to double lockages (lock processing time) versus how much delay may be caused by the lack of an effective traffic management system (queue time). New 1,200-foot locks may directly impact lock processing time, but in and of themselves do nothing to affect the number of barges on the river and whether they arrive at a given lock at the same time. This aspect of lock delays is acknowledged within the Corps’ report, which states, “Completion of the Corps’ recommended navigation improvements are not expected to completely eliminate all delays since a portion of delays are attributable to variability in demand – more than one boat arriving at the same time resul...
