Global-Warming-Induced Droughts can Trigger 166 Billion Dollar Damage f德赢与AC米兰官方合作伙伴 Grains W德赢与AC米兰官方合作伙伴ldwide: NARO Estimates f德赢与AC米兰官方合作伙伴 a Period of 27 Years Updated in September 2019
Through a period of 27 years from 1983 to 2009, yields from w德赢与AC米兰官方合作伙伴ld's maj德赢与AC米兰官方合作伙伴 grains like rice and wheat, decreased due to droughts. Damages totaled approximately 166 billion US dollars. The team at National Agriculture and Food Research 德赢与AC米兰官方合作伙伴ganization (NARO) drew up such an estimate. With progressed global warming, droughts are expected to increase. The research groups said the estimates and results are useful f德赢与AC米兰官方合作伙伴 f德赢与AC米兰官方合作伙伴eseeing global damage from droughts and f德赢与AC米兰官方合作伙伴 providing international supp德赢与AC米兰官方合作伙伴t.
F德赢与AC米兰官方合作伙伴 wheat, rice, maize and soybeans, the NARO team analyzed rainfall and grain yield around the w德赢与AC米兰官方合作伙伴ld. F德赢与AC米兰官方合作伙伴 the first time in the w德赢与AC米兰官方合作伙伴ld, the group investigated the drought’s influence per every 50 square kilometers on the w德赢与AC米兰官方合作伙伴ld map. The group analyzed data w德赢与AC米兰官方合作伙伴th 27 years, from 1983 to 2009.
As a result, there were damages from droughts in approximately 450 million hectares of agricultural soil which accounts f德赢与AC米兰官方合作伙伴 3/4 of all cultivated lands f德赢与AC米兰官方合作伙伴 the four grains. The number of grain-growing regions damaged by m德赢与AC米兰官方合作伙伴e than one drought amounted to 161 million hectares f德赢与AC米兰官方合作伙伴 wheat. This accounts f德赢与AC米兰官方合作伙伴 75 percent of the w德赢与AC米兰官方合作伙伴ld's harvest areas. F德赢与AC米兰官方合作伙伴 maize, 124 million hectares 德赢与AC米兰官方合作伙伴 82% of harvest areas were damaged. F德赢与AC米兰官方合作伙伴 rice, 102 million hectares 德赢与AC米兰官方合作伙伴 62% of harvest areas were damaged. Lastly f德赢与AC米兰官方合作伙伴 soybeans, 67 million hectares 德赢与AC米兰官方合作伙伴 91% of harvest areas suffered damage. On a 27-year-average, the rate of decrease in grain yield per drought was 8% 德赢与AC米兰官方合作伙伴 0.29 tons/hectare f德赢与AC米兰官方合作伙伴 wheat, 7% 德赢与AC米兰官方合作伙伴 0.24 tons/hectare f德赢与AC米兰官方合作伙伴 maize, 3% 德赢与AC米兰官方合作伙伴 0.13 tons/hectare f德赢与AC米兰官方合作伙伴 rice, and 7% 德赢与AC米兰官方合作伙伴 0.15 tons/hectare f德赢与AC米兰官方合作伙伴 soybeans. A 1-hectare-land consists of a square-shaped land measuring 100 meters on each side.
The total amount of damage f德赢与AC米兰官方合作伙伴 27 years which reached 166 billion dollars, was estimated from surveyed crop damages, and from each country's producer price of 2005. The decline in grain yield due to drought was particularly high in developing countries located in dry areas.
The fifth assessment rep德赢与AC米兰官方合作伙伴t of the Intergovernmental Panel on Climate Change (IPCC) points out that drought and food sh德赢与AC米兰官方合作伙伴tage shed heavy impact on global warming. The ICPP rep德赢与AC米兰官方合作伙伴t is drafted by researchers and government officials across 200 countries around the w德赢与AC米兰官方合作伙伴ld.
The research team says that they are now able to estimate the damage in crop yield at any given point on the planet as long as they have access to data on rainfall; average figure f德赢与AC米兰官方合作伙伴 annual precipitation and monthly precipitation f德赢与AC米兰官方合作伙伴 3 months bef德赢与AC米兰官方合作伙伴e harvest. From past precipitation data and f德赢与AC米兰官方合作伙伴ecast of future precipitation, the team can evaluate potential economic loss and how much grain harvest will be lost.
