Global Impact of Biotech Crops:
Socio-Economic and Environmental Effects in the First Ten Years of
Commercial Use,
AgBioForum
Volume 9 // Number 3 // 2007
Genetically modified (GM) crops have now been grown commercially on a
substantial scale for ten years. This paper assesses the impact this
technology is having on global agriculture from both economic and
environmental perspectives. It examines specific global economic impacts
on farm income and environmental impacts of the technology with respect to
pesticide usage and greenhouse gas emissions for each of the countries
where GM crops have been grown since 1996.
- The analysis shows that there have
been substantial net economic benefits at the farm level amounting to $5
billion in 2005 and $27 billion for the ten year period.
- The technology has reduced pesticide
spraying by 224 million kg (equivalent to about 40% 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 pesticide use by more than 15%
- GM technology has also significantly
reduced the release of greenhouse gas emissions from agriculture, which,
in 2005, was equivalent to removing 4 million cars from the roads.
Key words: Yield, cost, income, environmental impact quotient, carbon
sequestration, GM crops.
GM Crops: The First Ten Years - Global
Socio-Economic and Environmental Impacts
ISAAA Briefs 36-2006
This study presents the findings of
research into the global socio-economic and environmental impact of GM crops
in the ten years since they were first commercially planted on a significant
area. It focuses on the farm level economic effects, the environmental
impact resulting from changes in the use of insecticides and herbicides, and
the contribution towards reducing greenhouse gas (GHG) emissions.
