According to Graham Brookes, director of PG Economics and co-author of the report, a majority (55 percent) of the 2010 farm income gains went to farmers in developing countries. Ninety percent of these are resource poor on small farms.
The report also showed substantial environmental benefits. Crop biotechnology had contributed to greatly reducing the release of greenhouse gas emissions from agricultural practices. This results from less fuel use and additional soil carbon storage from reduced tillage biotech crops. In 2010, the reduction in carbon dioxide from the atmosphere was equivalent to taking 8.6 million cars off the road for one year.
The PG Economics annual crop biotechnology global impacts report quantifies the impact of agricultural biotechnology on the environment and on farmer incomes since biotech’s commercialization in 1996. Its goal is to give insights into the motivations behind why so many farmers around the globe have adopted crop biotechnology and continue to use it in their production systems since the technology first joined the widespread commercial market in the mid 1990s.
The report draws, and is largely based on, the considerable body of peer reviewed literature available that has examined the economic and other reasons behind farm level crop biotechnology adoption, together with the environmental impacts associated with the changes.
KEY FINDINGS OF THE REPORT
Biotech crops have contributed to significantly reducing the amount 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 2010, this was equivalent to removing 19.4 billion kg of carbon dioxide from the atmosphere or equal to removing 8.6 million carsfrom the road for one year.
Crop biotechnology has reduced pesticide spraying (1996-2010) by 438 million kg (-8.6%). As a result, the environmental impact associated with herbicide and insecticide use on the area planted to biotech crops decreased by 17.9 percent.
Farmers who use improved seeds and grow biotech crops have seen substantial net economic benefits at the farm level amounting to $14 billion in 2010 and $78.4. billion for the 15 year (1996-2010)period.
Of the total farm income benefit, 60 percent ($46.8 billion) has been due to yield gains, with the balance arising from reductions in the cost of production.
A majority (55 percent) of the 2010 farmer income gains went to farmers in developing countries, 90 percent of which are resource poor and small farms.
Since 1996, biotech traits have added 97.5 million tonnes and 159.4 million tonnes respectively to global production of soybeans and corn. The technology has also contributed an extra 12.5 million tonnes of cotton lint and 6.1 million tonnes of canola.
Over the 15-year period covered in this report, crop biotechnology has consistently provided important economic and production gains, improved incomes and reduced risk for farmers around the world that have grown GE crops.
The environment in user countries is benefiting from farmers using more benign herbicides or replacing insecticide use with insect resistant GE crops.
The reduction in pesticide spraying and the switch to no till cropping systems is also resulting in reduced greenhouse gas emissions.
The majority of these benefits are found in developing countries.
The advantages of advanced seed technology for farmers in developing countries come at a time when good availability is becoming more of an issue around the world. The population continues to grow, but for many farmers, their ability to produce food remains stuck in the past. In order to double food production by 2050 to meet demand, new seed technologies must be utilized.
Because biotech-enhanced plants have a built-in resistance to pests, growers are using fewer chemical sprays, which is better for the environment. Also, biotech crops thrive without the need for tilling the soil. This uses less fuel on the farm and allows carbon to remain in the soil, enhancing both air and soil quality.
