What irrigated crop takes up three times more US landmass than corn?

What irrigated crop takes up three times more US landmass than corn?
Look no farther than your front lawn.

This is a story that was released a few years ago, but is still very relevant: people's lawns are slurping up a huge amount of water, fertilizer and herbicides, but giving very little back.

I'm going to try to keep this post from going too much into the benefits of urban gardens, and I know it leaves out those who live in apartments, but the impact of your (or your landlord's) lawn is something you should consider:
  • If you water your lawn, what time of day is it - think of evaporation.
  • If you water your lawn, is there runoff onto your driveway or sidewalk?
  • Could your lawn be doing more? Food, flowers and grass alternatives all make more of a positive impact than a lawn.
This is not to say that you should not have a lawn altogether - it is a very nice luxury - but think about how much water you use (dried out grass doesn't need to be mowed!) and if there are any areas in your yard that would work for flowers, bushes, vegetables or berries.

The world is facing many macro issues and quite honestly sometimes it makes you feel a bit helpless. But, as they say, change starts at home, and your personal water / land usage can make a positive impact on the world.

Other tips for saving water:
  • Turn off the faucet while shaving or brushing your teeth
  • Wash only full loads of dishes and laundry
  • Fix dripping and leaking faucets and toilets
  • Take shorter showers
  • Wash cars less frequently
  • Water lawns and gardens on alternate evenings, not every day
  • Raise your lawn mower blade height; longer grass needs less water
