A new study by Dr. Clive James,
Chairman of ISAAA, confirms
that in 2001, global area of transgenic or GM crops was 52.6
million hectares (m has.) or 130 million acres, representing an
increase of 8.4 million hectares, or 20 million acres over 2000.
The principal GM crops were soybean (33 million hectares), corn
(10m has.), cotton (7m has.) and canola (3m has.). These GM
crops were grown in 13 countries by about 5 million farmers,
over 75% of whom were small resource-poor farmers growing Bt
cotton in developing countries. The study presents a global
overview of the cotton crop, an assessment of the performance of
Bt cotton to-date, and its future global potential. The focus on
developing countries is consistent with ISAAA's mission to
assist developing countries in assessing the potential of new
technologies.
OVERVIEW OF THE GLOBAL COTTON CROP
- Of the global 33.5 million
hectares (83 million acres) of cotton worth $20 billion,
approximately 70% are grown in developing countries. Asia has
up to 60% of world cotton, Africa up to 15% with <5% in Latin
America. There are approximately 20 million cotton farmers
globally, 97% of whom farm in developing countries -- most are
small resource-poor farmers growing 2 hectares or less of
cotton.
- Insect pests are a major
problem in cotton and yield losses and insecticides cost
cotton farmers $5 billion annually -- 20% of global
insecticides are used on cotton. Cotton farmers used $1.7
billion worth of insecticides in 2001. A novel and very
effective method of controlling the major insect pests of
cotton is through genetically modified cotton with "Bt genes"
from a soil bacterium, Bacillus thuringiensis (Bt).
- Since 1996, 13 million has. of
Bt cotton have been successfully deployed in nine countries, 7
developing and 2 industrial; these include USA, Mexico,
Argentina, and Colombia (pre- commercial) in the Americas,
China, India, Indonesia and Australia in Asia, and South
Africa on the African continent.
"Countries that have introduced
Bt cotton have derived significant and multiple benefits --
these include increased yield, decreased production costs, a
reduction of at least 50% in insecticide applications, resulting
in substantial environmental benefits to small producers, and
significant economic and social benefits," said Dr. James.
SIGNIFICANT ECONOMIC, ENVIRONMENTAL AND SOCIAL BENEFITS
ASSOCIATED WITH Bt COTTON
Productivity Benefits. Yield increases for Bt cotton range from
5 to 10% in China, 10% or more in the US and Mexico, 25% in
South Africa. In the US in 2001, Bt cotton increased lint
production on 2 million has. by over 84,000 metric tons (MT)
valued at $115 million. In China, seed cotton production on 1.5
million has. of Bt cotton increased by 514,000 MT.
Environmental Benefits. The major benefit has been a decrease of
50% in the number of insecticide sprays/season, which in turn
reduced insecticide residues that could potentially runoff into
watersheds and aquifers: a decrease of 14 sprays in China (from
28 to 14 sprays), 7 in S. Africa, and 2 in the USA. Global
insecticide savings attributed to Bt cotton in 2001 were 10,500
MT of insecticide (active ingredient, a.i.), equivalent to 13%
of the 81,200 MT (a.i) of all cotton insecticides used globally
in 2001. From a health perspective, cotton farmers in China and
South Africa applying insecticides by hand with knapsacks, have
significantly less potential exposure to insecticides when using
Bt cotton.
Economic benefits. The economic advantage of Bt cotton versus
conventional cotton results from Bt cotton's superior control of
insect pests which results in higher yields, cost savings of 50%
on insecticide and labor, which are partially offset by the
higher price of Bt cotton seed. In the US in 2001 economic gain
for Bt cotton was $50/ha and > $100 million nationally. In
China, economic gain from Bt cotton was $500/ha with a national
benefit of $750 million. In China in 2001 over 4 million
resource-poor
cotton farmers as well as several thousand in the Makhathini
Flats in South Africa derived significant economic benefits from
Bt cotton, supporting the 2001 UNDP Human Development Report
thesis that biotechnology can contribute to the alleviation of
poverty.
Social benefits. Bt cotton significantly increases income and
saves time, which is particularly valuable for small
resource-poor Bt cotton farmers in developing countries. In
China, the increased income allows poor farm families to spend
more on food and increase nutritional standards. In South
Africa, where 50% of the cotton farmers are women, Bt cotton
gives them more time to care for children, the sick, and/or
generate additional income from other activities.
"It is important that a human face is put on the benefits of Bt
cotton," said Dr. James. "For the average cotton holding of 1.7
hectares in the Makhathini Flats in South Africa, in a typical
season, a woman farmer is relieved of 12 days of arduous
spraying, saves over 1,000 liters of water (over 250 US
gallons), walks 100 km less, has less potential exposure to
insecticides, and increases her income by approximately $85 per
season, through using Bt cotton, rather than conventional
cotton."
GLOBAL POTENTIAL OF Bt COTTON
- Bt cotton occupies 4 million
hectares today but has the potential to deliver significant
benefits on at least half of the world's 33.5 million has. of
cotton with medium to high insect pest levels. With optimal
deployment of Bt cotton the projected annual insecticide
saving is estimated at 33,000 MT (a.i), equivalent to 37% of
the 81,200 MT (a.i) of cotton insecticides used globally in
2001.
- To-date, nine countries have
adopted Bt cotton and are benefiting, but what about the fifty
key countries that grow cotton throughout the world. The
challenge is to provide the same opportunity for the potential
beneficiary countries, with small to modest areas of cotton,
in the developing world. There are 30 such developing
countries, 21 in Africa, five in Asia and four in Latin
America that grow small to modest areas of cotton. Experience
to-date in several developing countries has clearly
demonstrated that Bt cotton can deliver significant economic,
environmental, and social benefits to millions of
resource-poor farmers that are assigned high priority by the
donor community.
- It is important that these
smaller cotton-growing countries with resource-poor cotton
farmers are offered the option of commercial access to Bt
cotton so that they are not disadvantaged by being denied the
significant benefits that accrue to adopters of the
technology. The case for providing more developing countries
the option of sharing in the substantial environmental,
economic and social benefits delivered by Bt cotton to
millions of resource-poor cotton farmers in developing
countries on millions of hectares over the last six years,
represents a challenge for both the donor community and the
developing countries which are the potential beneficiaries.
