Popular thinking about how to improve food systems for the better often misses the point, according to the results of a three-year global study of salmon production systems. Rather than pushing for organic or land-based production, or worrying about simple metrics such as "food miles," the study finds that the world can achieve greater environmental benefits by focusing on improvements to key aspects of production and distribution. http://www.physorg.com/news178297283.html Space & Earth Tue, 24 Nov 2009 15:16:35 EST news178297283 (PhysOrg.com) -- How much energy we use to produce food could be cut in half if Americans ate less and ate local foods, wolfed down less meat, dairy and junk food, and used more traditional farming methods, says a new Cornell study. http://www.physorg.com/news137776425.html Space & Earth Tue, 12 Aug 2008 16:13:45 EST news137776425 An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. It is therefore of paramount importance that ways of reducing this significant fuel consumption in the US food system are found. In a paper just published in the Springer journal Human Ecology, David Pimentel and his colleagues at Cornell University in New York set out a number of strategies which could potentially cut fossil energy fuel use in the food system by as much as 50 percent. http://www.physorg.com/news136028669.html Space & Earth Wed, 23 Jul 2008 10:44:29 EST news136028669
