Globally, Humanity produces more food than ever, but that harvest is concentrated in just a fist of the bread surface.
More than One-third of the world’s exports in the world and barley Come from Ukraine and Russia, for example, for example. Some of these very productive agricultural vehicles, including large crop regions in the United States, are on the way to see the sharpest drops in harvest due to climate change.
It is a bad news not only for farmers, but also for everyone who eats – especially as it becomes more difficult and more expensive for feeding the pumps, in the world, according to the new study published in the magazine Nature.
Under a moderate scenario of greenhouse gas emissions, six key crops for connecting will see 11.2 percent decrease until the end of the century, in comparison to the world without heating, even as farmers try to adapt. And the largest drops do not appear in poor, marginal agricultural countries, but in places that are already main food producers. These are regions like the American Middle West that are blessed with good soil and ideal weather for raising staples such as corn and soybeans.
But when it is less than ideal, it can drastically reduce agricultural productivity. Extreme time has already begun to eat in harvests this year: the flood had Destroyed rice in Tajikistan, Cucumbers in Spainand Bananas in Australia. Heavy Storms in the US this spring caused millions dollar damage to crops. In recent years, severe heat has led to large falls in Blueberries, olives and grapes. And as climate change, average temperature and variable paid-out, while weather events are, while weather events are like drought and floods that reach larger extremes wipe the harvests more often.
“It is not a mystery that climate change will affect our food production,” Andrew Hultgren, agricultural researcher at the University of Illinois Urban-Champaign. “It is the most exposed sector in economy.”
Farmers do what they can test Different crop varieties It can better withstand changes in climate, switching time when they are sowingAdjusting their use Fertilizers and waterand investing in Infrastructure like water tank.
The question is whether these adaptations can continue to keep the tempo with heating. In order to understand that, Hultgren and his team watched the crop data and weather from 54 countries around the world who returned to the 1940s. They especially watched that farmers have adapted changes in climates that have already happened, focusing on corn, wheat, rice, cash registers, sire and soybeans. Combined, these crops provide two-thirds calories of humanity.
In nature, Hultgren and his team reported that at all, adaptation could slow some crop losses due to climate change, but not all of them.
And the reduction of our food production can be pagual: for each degree of heating Celsius, global food production will probably reduce 120 calories per person per day. This even takes into account how climate change can break up the season longer and how many carbon dioxide in the atmosphere can encourage plant growth. In a moderate scenario of gas gardens’ gas emissions 2 and 3 degrees of Celsius heating up to 2100– Risk revenues and adaptations would only deal with only one third of crop losses around the world.
