The ‘invenTion’ of wheaT
BY GIO BrAIDOttI
in 2010, wheat was grown on more land than any other commercial
food—240 million hectares—and world trade in wheat was greater than
for all other crops combined. World production totalled 651 million tonnes,
second only to maize and roughly on par with rice (672 million tonnes).
it is an amazing success story. Wheat was one of the first cereals ever
domesticated, originating in the eastern Mediterranean region spanning
southern Turkey, north-western iraq, syria, lebanon, jordan, israel,
Palestine, cyprus, the sinai Peninsula and the ethiopian Highlands.
Recent findings narrow the first domestication of wheat to a small region
of south-eastern Turkey in about 9000 Bce (although exploitation of wild
wheat dates back to 23,000 Bce). domestication is considered a key factor
in the emergence of city-based societies including those in the nile delta,
and in the Babylonian and assyrian empires.
With domestication came technological innovation, primarily to
facilitate tillage as a way to loosen and aerate the soil, mix in nutrients and
destroy weeds. Tillage, too, began in the eastern Mediterranean, first in the
form of digging sticks 12,000 years ago and evolving into spades and then
triangular blades. The first wooden ploughs were likely pulled by farmers,
with animals recruited about 3,000 years ago in Mesopotamia (the area
between the Tigris and euphrates rivers in iraq, north-eastern syria and
Throughout early history, soil tillage had more in common with current

conservation agriculture than with modern ploughing practices due to
the intense labour involved. To plough one hectare with animal traction, a
farmer typically has to walk 30–40 kilometres.
With the industrial Revolution came the next wave of innovation,
starting with jethro Tull (1674–1741), who revolutionised horse-drawn farm
machinery, and culminating in the replacement of animals with tractors.
Many farmers and agricultural experts started to believe that the more they
tilled, the higher the yield they achieved. Powerful ploughs became icons of
The combination of wheat and plough proved incredibly adaptable.
Wheat is able to grow from near-arctic regions to the equator, from sea

colonial powers took wheat and the modern plough to north and south
america, asia, australia and africa, where it became a primary tool for
developing newly cultivated land.
But the same techniques that brought bounteous harvests in cool,
wet regions were gradually found to condemn farmland in warmer climates
to soil erosion and degradation. The last landmasses to adopt the plough
were also the first to abandon it in favour of conservation agriculture and
