From late 2007 through 2008, the global price of food saw an unprecedented upwards spike in prices, measured by the UN’s food price index, a broad measure of food prices. That spike was followed by another one in 2010 through early 2011 (see chart).
Here in the United States, we hardly felt the pinch at all. Food prices for the average American in the grocery store have almost no link to world food prices – as marketing, transportation, and processing can account for up to 80% of the total cost of food in the grocery store. However, major grain importing countries are sorely affected by these price spikes. For instance, as the Egyptian government continues to negotiate a new IMF loan, a sticking point is that over 9% of its total budget outlay is devoted to subsidizing food.
A team of researchers from the University of Texas at Austin has released a detailed report on energy use in pumping, treating, delivering, and preparing water for end use makes up no less than 12.6 percent of the nation’s total annual energy consumption is devoted to the task.
Published in September’s issue of Environmental Research Letters, a peer-reviewed scientific journal of the highest standing, the report details the investigation conducted by the team as they traced water from its source to the taps of average American households and back again. The study focused on each aspect of water delivery, including pumping from natural sources, building and maintaining reservoirs, treating the water for safety and then pumping it to individual residences and businesses, including those in the industrial sector.
