Climate-friendly technologies should reach farmers urgently
KEY HGHLIGHTS:

In recent years, there has been increasing focus on the role of methane as a driver of climate change. Traditionally, conversations on global warming had much to do with energy, industry and transport. However, there is now evidence that a quarter of the global emissions are products of agriculture and land-use changes.

According to the IPCC, more than 40 per cent of methane emissions come from farms or are an outcome of peatland destruction. The pledge by more than 80 nations, helped by the US and EU, to cut emissions of this GHG (greenhouse gas) by 30 per cent is, therefore, an important step in global warming mitigation efforts. But the announcement should be read with a number of caveats. Such pledges are commonplace at UNFCCC meets.

As a global warming agent, methane is 80 times more powerful than carbon dioxide in its first 20 years in the atmosphere. The latter, however, stays in the atmosphere for much longer. Cutting methane emissions, therefore, is seen as a potent way of mitigating global warming in the near term. While much of the contentious aspects of curbing emissions of this GHG pertain to agriculture, the oil and gas industry — especially natural gas, whose popularity as a relatively cleaner fossil fuel has led to a 50 per cent increase in its use in the past 10 years — is the second-highest emitter of this gas. Persuading people to change their dietary or farming practices can be a tricky proposition but slashing methane emissions from other sectors can be a relatively straightforward matter — even profitable for the industry in the long run. The International Energy Agency estimates that the fuel industry can achieve a 75 per cent reduction in methane emissions using existing technologies.

WAY FORWARD

India is amongst the top three emitters of this gas. It’s heartening, therefore, that agriculture research institutes in the country have started work on farmer-friendly technologies to reduce emissions from the livestock sector. Conversations have also begun on ways to change paddy cultivation practices to make them climate-friendly. These technologies must reach the farmers at the earliest and India along with other countries must try to achieve the nationally determined contributions at the maximum capacity.
