We're trying to find indigenous solutions, because our realities are very different from the West." (See 10 things...

So the emphasis for Indian scientists is on indigenous solutions. "We know we cannot count on high-quality feed and fodder," says Singhal. "No one will be able to afford it. What we have done instead is develop cheaper technologies and products." One example is urea-molasses-mineral blocks that are cheap, reduce methane emission by 20%, and also provide more nutrition, so they're easier to sell to illiterate farmers who don't know...
...microbes that thrive in oxygen-free environments like cows' guts, where they convert the available hydrogen and carbon (by-products of digestion) into methane, a colorless, odorless gas. "We encourage well-to-do farmers to use oilseed cakes, which provide unsaturated fatty acids that get rid of the hydrogen," Singhal says. Another solution is herbal additives. Some commonly used Indian herbs such as shikakai and reetha, which go into making soap, and many kinds of oilseeds contain saponins and tannins, substances that make for lathery, bitter meals but block hydrogen availability for methogens.
