Muuntogeeniset lajikkeet hyödyttävät eniten kehitysmaiden viljelijöitä

Carpenter JE. Peer-reviewed surveys indicate positive impact of commercialized GM crops. Nature Biotechnology 2010; 28:319–321
A large scale analysis of farmers experience with GM crops concludes that biotech crops have a positive impact on economic performance and yields for farmers around the world,
especially those in developing countries.
An analysis of 49 peer-reviewed publications reporting on farmer surveys that compare yields and other indicators of economic performance of GM and non-GM crops
The main GM traits evaluated are insect-resistance and herbicide-tolerance
74% of yield comparisons of biotech and conventional crops showed positive results for adopters of biotech crops versus non-adopters
When looking to developing countries alone, this number mounts up to 82 percent
The average increases for developing countries range from 16 percent for insect-resistant corn to 30 percent for insect-resistant cotton.
72 %t of the results are positive when GM crops are compared with their conventional counterparts
For herbicide-tolerant crops, 71% show a positive impact on economic performance
For insect-resistant crops, 74% show a positive impact on economic performance
Influence of GMOs on the environment:
Biotech crops help preserve the environment by facilitating conservation tillage and reducing the number of applications of insecticides
