Water Me Not

Maybe we’re coddling our plants.  Maybe they, too, can do more with less.  Check out this article from the San Francisco Chronicle.  There might be room to reduce the amount of water that is budgeted for irrigation in the design of rainwater harvesting systems.

It wasn’t by choice that Dan Lehrer cut off the water supply to his apple trees. When the irrigation system on his organic farm in Sebastopol broke down five years ago, repairing it was too costly, so his entire orchard of Red Rome Beauty and Golden Delicious went cold turkey.

Accustomed to enjoying drip irrigation 24 hours a day for roughly five months at a time, the trees were thirsty and stressed, but began producing smaller fruit that was less waterlogged and resulted in notably richer and crisper apples. They ripened later and kept better in storage. Meanwhile, Lehrer saved a hefty chunk on his water bill and conserved thousands of gallons each season, both from his well and from the public supply – notable in this low-water area of western Sonoma County. His apples haven’t seen a drop from the tap since.

Auto-Free NY’s Plan for Improving the City through Better Transit

Come hear how it works this week.
Tuesday, Oct 28. 6-8pm
Auto-Free NY presents an open forum on key transportation issues. Moderated by Jeffrey Gold, Vice-President, Institute for Rational Urban Mobility.

More info on Sustainable Streets in New York City in SF this week from SPUR:
Wednesday, Oct 29. 12:30 – 1:30pm. SPUR Office, 312 Sutter St. (at Grant), 5th Floor. Close to the Powell St. BART station and several Muni lines. Feel free to bring a lunch. SPUR Forums are open to the public, free for members and $5 for non-members.

New York’s Department of Transportation has transformed in recent years into one of the country’s leading advocates for sustainable streets. Jon Orcutt, the agency’s Director of Policy, will discuss the agency’s strategic plan, released in April 2008, and the variety of projects and initiatives designed to align the department with the goals and challenges of Mayor Michael Bloomberg’s PlaNYC 2030 sustainability initiative

What’s “Humanure”??
Thursday, Oct 30. 7:30 – 9:00pm. 6th Street Community Center
638 East 6th St (btw Aves B and C), in Manhattan

Permaculture Solutions Lecture Series presents: “Humanure” Humanure – the odorous excretions of human beings – can be recycled using natural processes without creating environmental pollution. And it can be done in your own backyard. Joseph Jenkins will cover this topic at least a couple inches deep. Joseph Jenkins, a businessman, organic gardener and author of three books, is perhaps best known for the award-winning Humanure Handbook – A Guide to Composting Human Manure, which is making its way to various United Nations and international development networks, and has been translated into Korean, Hebrew, Spanish, Norwegian and Mongolian.  From the Green NYC Events calendar.

Have a Great Week!

  • Cheap air lines have lead to dramatically increased air travel within Europe, mostly to coastal towns with a resort industry springing up near the airports. But this is causing global warming issues that will take a long time to undo.
  • Families are actually using the Xebra electric car for neighborhood errands, spending $10/month to charge the car. But it will be hard to avoid attracting notice in one of them.

  • A never ending stream of plastic trash is inundating areas like northern Alaska or some islands in Hawaii. And cleanup isn’t going to solve the problems – the only way to fix the situation is to stop allowing trash into the oceans in the first place.
  • Another power strip has been developed that hooks up to your computer monitor via USB so that you can manage the power controls of each of your outlets on the strip. See how much power you’re saving as well.

  • NYC buses started going hybrid 4 years ago to try and reduce emissions, but they are having an even bigger payoff these days due to increased fuel prices, causing the city to exceed their budget for gasoline by 56% in April.
  • Glassmakers look at ways to reduce their energy needs as energy costs skyrocket.
  • NYC will start car-free Saturdays in August, where a series of major streets and avenues will create a car-free path from Lower Manhattan to Central Park.

  • McCain infuriates environmental groups that have in the past seen him as an ally for calling for offshore drilling in the Gulf of Mexico as part of his energy plan.  And to help out his party, Bush flips his previous opinion to say he’ll ask congress to open up the Gulf for drilling.  Another part of McCain’s policy is to build 45 new nuclear power plants by 2030.
  • Recycling machine brings recycling program to Tijuana, but also brings jobs to the poor who live in the dump and scavenge for a living.
  • Is Astroturf a green alternative to a grass field in California, where a lawn would require heavy maintenance and water use to survive the summer?
  • With the rise in gas prices, suburbs will start to disappear and smaller cities will rejuvenate. And those cities out west? Without AC, they’ll probably disappear as well. However, skyscrapers aren’t much more sustainable, so NYC and Chicago will shrink too as sources of natural gas get depleted.
  • Mayor Daley proposes bikes sharing the bus lanes while the city of Chicago catches up with the increased demand for bike lanes on the streets.
  • Its actually better for the environment to upgrade from a 15mph gas guzzler to a 20mph car, then it is from a 30mph sedan to a 45mph hybrid.  Because you’ll use less gas on your commute with the first one.  It would be better to rate cars in gallons per mile than miles per gallon if we are trying to preserve our oil reserves.
