Wealth in a cold climate

Dr William
Masters was reading a book about mosquitoes when inspiration struck. "There
was this anecdote about the great yellow fever epidemic that hit
Philadelphia in 1793," Masters recalls. "This epidemic decimated
the city until the first frost came." The inclement weather froze out
the insects, allowing Philadelphia to recover

If weather
could be the key to a city's fortunes, Masters thought, then why not to the
historical fortunes of nations? And could frost lie at the heart of one of
the most enduring economic mysteries of all — why are almost all the wealthy,
industrialised nations to be found at latitudes above 40 degrees? After two
years of research, he thinks that he has found a piece of the puzzle.
Masters, an agricultural economist from Purdue University in Indiana, and
Margaret McMillan at Tufts University, Boston, show that annual frosts are among
the factors that distinguish rich nations from poor ones. Their study is
published this month in the Journal of Economic Growth. The pair speculates
that cold snaps have two main benefits — they freeze pests that would otherwise
destroy crops, and also freeze organisms, such as mosquitoes, that carry
disease. The result is agricultural abundance a big workforce

The academics
took two sets of information. The first was average income for countries,
the second climate data from the University of East Anglia. They found a curious
tally between the sets. Countries having five or more frosty days a month
are uniformly rich; those with fewer than five are impoverished. The
authors speculate that the five-day figure is important; it could be the
minimum time needed to kill pests in the soil. Masters says: "For
example, Finland is a small country that is growing quickly, but Bolivia is
a small country that isn't growing at all. Perhaps climate has something to
do with that." In fact, limited frosts bring huge benefits to farmers.
The chills kill insects or render them inactive; cold weather slows the
break-up of plant and animal material in the soil, allowing it to become
richer; and frosts ensure a build-up of moisture in the ground for spring,
reducing dependence on seasonal rains. There are exceptions to the
"cold equals rich" argument. There are well-heeled tropical countries
such as Hong Kong and Singapore (both city-states, Masters notes), a result
of their superior trading positions. Likewise, not all European countries
axe moneyed — in the former communist colonies, economic potential was
crushed by politics.

Masters
stresses that climate will never be the overriding factor 一
the wealth of nations is too complicated to be attributable to just one factor.
Climate, he feels, somehow combines with other factors — such as the presence
of institutions, including governments, and access to trading routes — to
determine whether a country will do well. Traditionally, Masters says,
economists thought that institutions had the biggest effect on the economy,
because they brought order to a country in the form of, for example, laws and
property rights. With order, so the thinking went, came affluence.
"But there are some problems that even countries with institutions
have not been able to get around," he says. "My feeling is that,
as countries get richer, they get better institutions. And the accumulation
of wealth and improvement in governing institutions are both helped by a favourable
environment, including climate.

This does not
mean, he insists, that tropical countries are beyond economic help and destined
to remain penniless. Instead, richer countries should change the way in
which foreign aid is given. Instead of aid being geared towards improving
governance, it should be spent on technology to improve agriculture and to
combat disease. Masters cites one example: "There are regions in India
that have been provided with irrigation — agricultural productivity has
gone up and there has been an improvement in health." Supplying vaccines
against tropical diseases and developing crop varieties that can grow in
the tropics would break the poverty cycle.

Other minds
have applied themselves to the split between poor and rich nations, citing anthropological,
climatic and zoological reasons for why temperate nations are the most affluent.
In 350BC, Aristotle observed that "those who live in a cold climate .
. . are full of spirit". Jared Diamond, from the University of
California at Los Angeles, pointed out in his book Guns, Germs and Steel
that Eurasia is broadly aligned east-west, while Africa and the Americas
are aligned north-south. So, in Europe, crops can spread quickly across latitudes
because climates are similar. One of the first domesticated crops, einkorn
wheat, spread quickly from the Middle East into Europe; it took twice as
long for corn to spread from Mexico to what is now the eastern United
States. This easy movement along similar latitudes in Eurasia would also
have meant a faster dissemination of other technologies such as the wheel
and writing, Diamond speculates. The region also boasted domesticated
livestock, which could provide meat, wool and motive power in the fields Blessed
with such natural advantages, Eurasia was bound to take off economically.

John Gallup
and Jeffrey Sachs, two US economists, have also pointed out striking correlations
between the geographical location of countries and their wealth. They note that
tropical countries between 23.45 degrees north and south of the equator are
nearly all poor. In an article for the Harvard International Review, they
concluded that "development surely seems to favour the temperate-zone
economies, especially those in the northern hemisphere, and those that have
managed to avoid both socialism and the ravages of war". But Masters
cautions against geographical determinism, the idea that tropical countries
are beyond hope: "Human health and agriculture can be made better through
scientific and technological research," he says, "so we shouldn't
be writing off these countries. Take Singapore: without air conditioning,
it wouldn't be rich."
