Blackcurrant Breeding Programme, and Ribena, to develop new
strains of blackcurrant. They say that, “The aim is to produce a range
of cultivars with superior fruit quality, pest and disease resistance and
environmental adaptability in a changing climate. Two new varieties,
Ben Vane and Ben Kilbreck, were successfully grown on a farm in
Gloucestershire in 2008 and are now being grown commercially. Part
of the success of this project was due to a good relationship between
the partners and the UK farming community, which helped enable the
trial and uptake of this new species.”
Unfortunately, politics intrudes when it comes to GM foods. Africa,
which is likely to bear the brunt of climate change, has also been
subjected to sustained misinformation by environmental lobby groups.
Already, Uganda’s banana industry is being devastated by bacterial wilt.
Elsewhere in the region, cassava–a fundamental food staple formillions
– is being destroyed by two different viruses. In both cases there areGM
versions which can be planted now that solve this problem. However,
national anti-biotech legislation is in place to prevent GM agriculture.
The gradual changing conditions are aiding the spread of the
viruses that cause these agricultural epidemics. Aid agencies are fo-
cused on teaching farmers how to clean their equipment or purify their
seed-stock in order to stop transmission. Anathema is the discussion
of the successful use of GM alternatives.
Disaster is concentrating minds. Kenya is finally bringing their
biotech legislation up for review, but the expectation is that – without
legislative change – the region will be unable to farmeither bananas or
cassava within the next 30 years. There ismuch to gain from improving
our existing processes which – even without the incentive of climate
change adaptation – would be useful for company effectiveness.
The danger is not just to food security. We also have to cope with
increasingly violent and destructive weather extremes. Larger ocean
storms are speedily eroding coastal areas and advancing on both
commercial and residential property. Stabilising our shoreline to cope
with wave-activity is also needed. Improved weather prediction can
reduce loss of life.
BASF has developed a special elastomer polyurethane coating for
gravel (Elastocoast) which is then used to create coastal revetments.
These act to break and absorb wave action. The porous gravel absorbs
the water and permits it to drain safely. With sea levels projected to
rise by 50 cm over this century, numerous retaining walls, coastal
defences and dikes will need to be raised. As an engineering exer-
cise, it will be vast and expensive. BASF’s product is said to be both
renewable and low-cost.
Cotton, a highly water-intensive crop, could be displaced by new
processes for extracting fibres from other bast fibres, like flax and
hemp. And so it goes, with companies developing enhancements or
alternatives to products at risk to climate damage. Consultants and
companies specialising in supporting climate adaptation are already
hard at work. It’s already a multi-billion dollar industry active globally.
“Companies with expertise in water security are on the front lines
of addressing changing climate adaptation,” says Environmental
Business Initiative President, Grant Ferrier. “Several leading consul-
tancies have cut their teeth in Australia and other countries where
governments have been forced to come to terms with chronic water
scarcity. And now they’re bringing that expertise to Texas and parts of
the United States hit hard by drought and extreme heat.”
Legislation that acknowledges climate change would still be useful.
Like countries facing eminent famine and still refusing to recognise
that GM crops are a safe and already-existing solution, governments
similarly need to recognise that climate change has consequences
whether you believe in it or not.
