How renewable farming can solve problems of climate change and conflicts

By Dr Vandana Shiva

Climate change talks are often centred on renewable energy. Nobody talks about making farming renewable. Around 50 percent of global greenhouse gas emissions are due to chemical farming. It emits carbon dioxide from the burning of fossil fuel required to make chemicals.

Their origin goes back to World War II, when those manufacturing explosives using nitrogen realised that the same could be used to make fertilisers. After the world war, the factories could have shut down but those who had gotten used to profiteering did not want to quit. A whole new science of farming was raised and farmers were told that nitrogen fertilisers are good.

If we give it a thought, our pulses fix nitrogen as well. Their roots have rhizobium bacteria which fix nitrogen and give us good nutrition. But the green revolution did not have pulses. It focused on rice and wheat and the result is for everyone to see. Not only it cheated the earth of its natural nitrogen fixators, shortage of pulses also led to a rise in their prices.
