Socio-economic Impacts of Bt/ GM corn

The Bt corn was the first genetically modified crop which was approved by the Philippine Department of Agriculture way bank 2003. From the total area of 10,000 hectares planted to Bt corn in 2003, it increased the total area planted to all GM corn to 643,800 hectares with the following impacts:

1) The average yield of Bt corn compared with ordinary hybrid (OH) was 19% from 2003 to 2011. This was due to its excellent agronomic trait of corn borer resistance contributing to the increase in output.

2) The Bt corn, was more cost advantage versus OH due mainly to higher yield and lower cost of production from savings gained from not applying insecticide and labor associated with spraying.

3) The average real peso income advantage of Bt corn or net farm income was eight percent per annum due to the combined effects of the agronomic trait and cost savings from non-use of insecticides.

4) BT corn outperformed OH by 29% from 2003 to 2011 in terms of meeting household food and poverty thresholds and in global competitiveness. The average return on investment (ROI) of Bt corn across different seasons in different producing areas was 42% higher than OH corn producers.
