Climate Change and Agriculture: Biodiverse Ecological Farming Is the Answer, Not Genetic Engineering

Vandana Shiva @ Climate Story Tellers - Industrial globalised agriculture is heavily implicated in climate change. It contributes to the three major greenhouse gases: carbon dioxide (CO2) from the use of fossil fuels, nitrogen oxide (N2O) from the use of chemical fertilizers and methane (CH4) from factory farming. According to the Intergovernmental Panel on Climate change (IPCC), atmospheric concentration of CO2 has increased from a pre–industrial concentration of about 280 parts per million to 379 parts per million in 2005. The global atmospheric concentration of CH4 has increased from pre–industrial concentration of 715 parts per billion to 1774 parts per billion in 2005. The global atmospheric concentration of N2O, largely due to use of chemical fertilizers in agriculture, increased from about 270 parts per billion to 319 parts per billion in 2005.

Industrial agriculture is also more vulnerable to climate change which is intensifying droughts and floods. Monocultures lead to more frequent crop failure when rainfall does not come in time, or is too much or too little. Chemically fertilized soils have no capacity to withstand a drought. And cyclones and hurricanes make a food system dependent on long distance transport highly vulnerable to disruption.

Genetic engineering is embedded in an industrial model of agriculture based on fossil fuels. It is falsely being offered as a magic bullet for dealing with climate change. Read more.
