One in six countries facing food shortage:
Climate change main reason: UN
By John Vidal and Tim Radford
LONDON: One in six countries in the world face food shortages this
year because of severe droughts that could become semi-permanent under
climate change, UN scientists have warned. In a stark message for world
leaders who meet in Gleneagles next week to discuss global warming, Wulf
Killman, chairman of the UN food and agriculture organisation’s climate
change group, said the droughts that have devastated crops across Africa,
central America and south-east Asia in the past year are part of an
emerging pattern.
“Africa is our greatest worry,” he said. “Many
countries are already in difficulties ... and we see a pattern emerging.
Southern Africa is definitely becoming drier and everyone agrees that the
climate there is changing. We would expect areas which are already prone
to drought to become drier with climate change.”
The food and
agriculture organisation and the US government, both of which monitor
global food shortages, agree that 34 countries are now experiencing
droughts and food shortages and others could join them. Up to 30 million
people will need assistance because of the droughts and other natural
disasters such as the Asian tsunami.
The worst affected countries
include Ethiopia, Zimbabwe, Malawi, Eritrea and Zambia, a group of
countries where at least 15 million people will go hungry without
aid.
The situation in Niger, Djibouti and Sudan is reported to be
deteriorating rapidly. Many countries have had their worst harvests in
more than 10 years and are experiencing their third or fourth severe
drought in a few years, the United Nations said.
Climate change
could also trigger the growth of deserts in southern Africa. A report
published in Nature recently predicts that as greenhouse gases fuel global
warming, the dunes of the Kalahari could begin to spread. By 2099,
shifting sands could be blowing across huge tracts of Botswana, Angola,
Zimbabwe and western Zambia. Much of the region was covered by shifting
dunes more than 4,000 years ago.
“Dunes are composed of soft sand.
If you sift away their protective vegetation cover, and there is enough
energy in the wind, then that sediment has the potential to move,
especially if it is dry,” said David Thomas, of the University of
Oxford.
“In western Zambia there are quite a lot of these ancient
sand dunes. They were quite active 4,000 years ago, which isn’t long in
geological terms. There have been plenty of times when it has not been a
great place to live.” Severe droughts have also badly affected crops in
Cuba, Cambodia, Australia, Afghanistan, Vietnam, Morocco, Guatemala,
Honduras and Nicaragua. According to the UN’s famine early warning system,
16 countries, including Peru, Ecuador and Lesotho, face “unfavourable
prospects” with current crops.
In Europe, one of the worst droughts
on record has hit Spain and Portugal and halved some crop yields. Both
countries have applied to the EU for food assistance. In Morocco the same
regional drought has devastated farming and the government fears an influx
of people into the cities.
Researchers are reporting a general
drying of the land and growth of desertification in the Mediterranean
region. “The 20-year average clearly shows a dramatic increase of
desertification and drought,” said a leading agricultural economist,
Professor Giovanni Quaranta, of the University of Basilicata in southern
Italy.
Henri Josserand, the UN’s famine early warning system
director, said: “In southern Africa especially, there is no question that
drought has become much more frequent in the past few years.
There
has been a sequence of drought years for four or five years. What is
unusual is the repeat patterns”.
The situation in Malawi and
Zimbabwe is giving particular cause for concern. In Malawi, where a
government report suggests more more than 430,000 tonnes of maize will be
needed to avert the second food shortage in three years, one in three
people are expected to need help by the end of the year following poor
rains.
Thousands of people died in 2002-03 in what became known as
a “hidden famine”, which affected the poorest and remotest
people.
“It’s going to get rapidly worse and we will have to move
substantial amounts of food very fast,” said one non-governmental group
working in the worst-hit southern region of Malawi. In Zimbabwe, where the
effects of drought have been exacerbated by a deteriorating political
situation, 4 million people may need help this year, the US government’s
famine early warning system showed.
“In all rural districts of
Zimbabwe, crop production was poor and well below normal,” said a report
last week. UN sources suggest that getting food to the country will not be
difficult because neighbouring South Africa had a surplus this year, but
distribution in the politically volatile circumstances may be
hard.
A report by Britain’s leading development and environment
groups this week backed the UN studies that suggest Africa will most feel
the effects of drought and desertification under climate change, and will
experience continued food shortages.
“Africa is more exposed to the
impacts of climate change than many other regions in the world. Climate
change is happening, and it is affecting livelihoods that depend on the
natural environment, which, in Africa, means nearly everyone,” said Andrew
Simms, spokesman for the World Development Movement.—Dawn/The Guardian
