In the debating about the
future of our own nation or any nation there are realities that are often or
completely ignored. Along with this is
the unwillingness to look at history and related demographics to understand
what we could be in for.
One simple proposition is
that humanity needs food and water both to survive and to support activity and
growth. In much of the West the present
riches of supply and choice and ease of getting food has meant most of us have
forgotten hunger or the impact of food costs leaving little disposable income.
This might be about to
change. If it does a lot of other things will change and not for the
better. In today's Telegraph Ambrose Evans-Pritchard tells us that we are in danger
of declining crop yields at a time
when populations continue to increase steadily.
The article cites past
civilisations that have collapsed where there is a case for crop failure
arising not just from population pressure or climate but soil and resource
degradation as well. These three
horsemen of an apocalypse inevitably are joined by a fourth of human failings
and short sightedness.
In all the debates on
migration we are long on theory and very short on demographics or history. If
food supply reduction is uneven then some peoples will suffer more than
others. If their populations increase
then this may mean migration. If the
food deficit is serious this could be substantial. Then there are the basic figures.
One nation, a former British
colony, has a population of over 80 million.
Sixty years ago it was eight million.
There has been little inward migration.
It is possible for the outward migration to have fallen in proportion
but to have increased substantially in actual numbers. World wide there is the potential for major rises in population movement.
If food scarcity and cost is a major factor
then the trend will be from those with relatively worsening situations towards
those nations which do have food or the economic power to buy it from their
earnings.
An implication of the
research is that the favoured countries may diminish sharply both in numbers
and capability as the stresses spread from the badly affected areas to the
others along with the movement of peoples.
If the grain producers themselves encounter problems any crisis will
escalate rapidly.
In the UK now we have had
over half a century of good food availability at reduced costs. It has been a major factor in our modern
consumption economy. In the next decade or
two this could begin to change rapidly for a variety of reasons. It could happen to the USA as well and other
nations once blessed with a good surplus.
There was a time when
Thanksgiving was for the fact that there was food on the plate.
Imagine a triple whammy - economic downturn, global cooling then a big volcanic eruption. That would test our mettle.
