New (annual) study shows biotech crops have delivered significant
global economic and environmental benefits and are making important
contributions to global food production & security.
"Since 1996, biotech crop adoption has contributed to
reducing the release of greenhouse gas emissions from agriculture,
decreased pesticide spraying and significantly boosted farmers'
incomes," said Graham Brookes, director of PG Economics,
co-author of the report. "The technology has also made
important contributions to increasing the yields of many farmers,
reducing production risks, improving productivity and raising
global production of key crops. The combination of economic
and environmental benefit delivery is therefore making a valuable
contribution to improving the sustainability of global agriculture,
with these benefits and improvements being greatest in developing
countries"
Previewing the findings of the comprehensive study, the key
findings are:
• Biotech crops have contributed to significantly reducing
the release of greenhouse gas emissions from agricultural practices.
This results from less fuel use and additional soil carbon storage
from reduced tillage with biotech crops. In 2007, this was equivalent
to removing 14.2 billion kg of carbon dioxide from the atmosphere
or equal to removing nearly 6.3 million cars from the road for
one year;
• Biotech crops have reduced pesticide spraying (1996-2007)
by 359 million kg (-8.8%: equivalent to about 125% of the annual
volume of pesticide active ingredient applied to arable crops
in the European Union) and as a result decreased the environmental
impact associated with herbicide and insecticide use on the
area planted to biotech crops by 17.2%;
• Herbicide tolerant biotech crops have facilitated the
adoption of no/reduced tillage production systems in many regions,
especially South America. This has made important contributions
to reducing soil erosion and improving soil moisture levels;
• There have been substantial net economic benefits at
the farm level amounting to $10.1 billion in 2007 and $44.1
billion for the twelve year period. The farm income gains in
2007 is equivalent to adding 4.4% to the value of global production
of the four main biotech crops of soybeans, corn, canola and
cotton;
• Of the total farm income benefit, 46.5% ($20.5 billion)
has been due to yield gains, with the balance arising from reductions
in the cost of production. Two thirds of the yield gain derive
from adoption of insect resistant crops and the balance from
herbicide tolerant crops;
• Farmers in developing countries obtained the largest
share of the farm income gains in 2007 (58%) and over the twelve
year period obtained 50% of the total ($44.1 billion) gains;
• The cost farmers paid for accessing GM technology in
2007 was equal to 24% of the total technology gains (a total
of $13.2 billion inclusive of farm income gains ($10.1 billion)
plus cost of the technology payable to the seed supply chain
($3.17 billion)2;
• For farmers in developing countries the total cost
of accessing the technology in 2007 was equal to about 14% of
total technology gains, whilst for farmers in developed countries
the cost was 34% of the total technology gains. Whilst circumstances
vary between countries, the higher share of total technology
gains accounted for by farm income gains in developing countries
relative to the farm income share in developed countries reflects
factors such as weaker provision and enforcement of intellectual
property rights in developing countries;
• Since 1996, biotech traits have added 67.8 million
tonnes and 62.4 million tonnes respectively to global production
of soybeans and corn. The technology has also contributed an
extra 6.85 million tonnes of cotton lint and 4.44 million tonnes
of canola;
• Production of soybeans, corn, cotton and canola on
the areas planted to biotech crops, in 2007, were respectively
+29.8%, +7.6%, +19.8% and +8.5% higher than levels would have
otherwise been if GM technology had not been used by farmers;
• If GM technology had not been available to the (12
million) farmers using the technology in 2007, maintaining global
production levels at the 2007 levels would have required additional
plantings of 5.9 million ha of soybeans, 3 million ha of corn,
2.5 million ha of cotton and 0.3 million ha of canola. This
total area requirement is equivalent to about 6% of the arable
land in the US, or 23% of the arable land in Brazil.
