In the hardest hit areas, outages lasted two weeks or more. These failures led many observers to wonder if America’s aging electrical grid was up to dealing with emerging climate and other challenges.]]> http://blogs.ei.columbia.edu/2013/05/15/the-microgrid-solution/feed/ 1 http://blogs.ei.columbia.edu/2012/03/22/%e2%80%9cthe-story-of-water-in-ceara%e2%80%9d-%e2%80%93-new-infographic-from-the-columbia-water-center/ http://blogs.ei.columbia.edu/2012/03/22/%e2%80%9cthe-story-of-water-in-ceara%e2%80%9d-%e2%80%93-new-infographic-from-the-columbia-water-center/#comments Thu, 22 Mar 2012 13:30:05 +0000 Lakis Polycarpou http://blogs.ei.columbia.edu/?p=24223 As population grows and demand for food and products increase, so does our demand for water.

The practice he developed involved selective pruning of shrub shoots to a main stem, which was then pruned of its lower leaves and branches.
