le pliage small shopper le pliage small shopper Food Production May Cause Almost One Third Of Greenhouse Gas

OSLO, Oct 31 Reuters Food production accounts for up to 29 percent of manmade greenhouse gases le pliage small shopper , twice the amount the United Nations has estimated comes from farming, a study published on Wednesday said.

Looking at emissions across the food system including forest clearance, fertiliser production and transport rather than just farming itself agriculture research organisation CGIAR said much more work was needed to cut climate change emissions from food. estimates of 14 percent based on a narrower definition of farming. approach doesnt make sense, said Bruce Campbell, who heads the CGIAR research programme on climate change, agriculture and food security.

Many countries could make big cost savings by cutting emissions, he said. There are good economic reasons to improve efficiency in agriculture, not just to cut greenhouse gas emissions.

China, for instance, could sharply reduce emissions with more efficient manufacture of fertilisers. Britain could cut emissions by consuming lamb transported from more efficient farms in New Zealand rather than raising its own sheep.

Global changes in diet, shifting towards vegetarianism from meat, would also help. Growing crops to feed to cows, pigs or sheep takes up far more land and emits more greenhouse gases than producing crops for human consumption.


A separate report le pliage small shopper by the CGIAR climate programme indicated that climate change is likely to reduce yields of the three biggest crops judged by calorie production maize, wheat and rice in developing nations in coming decades.

That could force some farmers to make radical shifts to growing more heat, flood or droughttolerant crops, according to the report, Recalibrating Food Production in the Developing World.

More resilient crops including yam, barley, cowpea, millet, lentils, cassava and bananas could fill in the gaps caused by declining harvests of more sensitive crops, it said.

The worlds agricultural systems face an uphill struggle in feeding a projected nine to ten billion people by 2050. Climate change introduces a significant hurdle in this struggle, it said. The world population is now just above seven billion.

Every step of the food chain from the seed to the farm to the cooking pot is at risk, it said. Higher temperatures or floods could make it harder to store and transport food, for instance, meaning more outbreaks of foodborne illnesses.

This is not so much news as haggling over the extent of the problem of agriculture. Best practices tells us that neither monoculture factory farms nor selfcontained family farms are the best approach. Each thing needs to be looked at separately and the people who actually work in this area know it and are working on it. For example, while current monoculture practice of alternating corn and soya has improved production yield, it has resulted in secondary problems too much fertilizer use, erosion, etc. that can be mitigated by rotating in a number of other crops. But going all the way to each farm growing lots of different crops becomes inefficient also, wasting energy and resources.

Whatever the exact number, agriculture certainly does contribute significantly to the energy usage globally and should not be neglected in discussions of future energy needs. le pliage small shopper
