Does being a locavore add up?

As I’ve argued before (here) there are a number of reasons why buying food locally is probably the least sustainable basis on which to base your food buying preferences.

First, transport is only a small component of the total carbon emissions from agriculture.

Second, most food can’t be grown locally without resorting to potentially environmentally damaging practices like excessive application of fertiliser, irrigation or artificial heating of greenhouses.

Third, even where the local area is suitable for growing certain foods, it might not be the most environmentally efficient location for a particular food.

Fourth, producers in more distant locations might have superior farming practices to local growers. Fifth, the environmental and economic cost of moving people is higher than the cost of transporting their food.

Now Stephen Budiansky has assembled an array of interesting factoids in this NY Times oped, Math lessons for locavores, to show the folly of being a locavore. He’s a stylish writer so you might want to read the full article; otherwise here are a few key quotes:

  • “Whether it’s grown in California or Maine, or whether it’s organic or conventional, about 5,000 calories of energy go into one pound of lettuce. Given how efficient trains and tractor-trailers are, shipping a head of lettuce across the country actually adds next to nothing to the total energy bill. Read the rest of this entry »

Where will the money come from?

According to Paul Austin in The Age (29/11/10), there’s little doubt that infrastructure inadequacies weighed heavily on voters’ minds in last Saturday’s election. His list of problems includes overcrowded trains, congested roads, the Myki debacle and long hospital waiting lists.

The pressure to “fix” these problems from voters in the eastern suburbs and sandbelt electorates that fell to the Coalition on Saturday will be immense.

The new Premier, Mr Baillieu, might therefore find it worthwhile to look at this report on public sector borrowing by Dr Nicholas Gruen (summary here).

Dr Gruen contends that governments in Australia have focussed on the cost of debt but have ignored the benefits. They’ve reduced the budget deficit to zero but exchanged it for an infrastructure deficit. Their constituents have saved on debt repayments, but:

they are paying inflated tolls on roads and heavy mortgage repayments that reflect the lack of land release and the loading of infrastructure charges onto the land that has been released. And they are paying with their time as they wait at peak hour in traffic that has slowed to a crawl or crowd into late trains and buses.

Thanks to the culture of strict fiscal rectitude that dominates modern government thinking, new debt has been kept off the government’s balance sheet by funding infrastructure in other ways – partly through asset sell-offs but mostly via Public Private Partnerships (PPPs).
