The World Is Producing More Food than Ever—but Not for Long

This story is basically Present Vox And part of it Climate desk Cooperation.

Worldwide, Humanity is producing more food However, that crop is centered on only a few rustbuskets.

More One -third of the world’s wheat and barley export Come from Ukraine and Russia for example. The United States has a few tracks of these high-productive farms, including the main crop-growth region of the United States to see the most intense drops in crop harvesting due to climate change.

This is not only for farmers, but also bad news for those who eat – especially since it is more crowded, feeding the world of Hung becomes more difficult and expensive, a new survey published in the journal NatureThe

Under the scene of a medium greenhouse gas emissions, six main crops will be reduced by 11.2 percent at the end of the century without warming, even farmers are trying to adapt. And the biggest drops are not happening in the poor, more marginal farms, but in places that are already main food producers. These are territories like the US midwest that have received good soil and ideal weather blessings for raising staples like maize and soy.

But when that weather is lower than the ideal, it can severely reduce agricultural productivity. Extreme weather has already begun to harvest this year: flooded Destroy rice in Tajikistan, MossAnd AustraliaThe Fatal storms in the United States this spring The loss of crops is a few million dollarsThe In the past years, severe heat has been reduced as a result Blueberries, olives and grapesThe And with climate change, the average temperature and changing rainfall types can reduce yields, while on the other hand, weather incidences, such as drought and floods, can remove more crops.

“It is not a mystery that climate change will affect our food production,” says Andrew Haltgren, an agricultural researcher at the University of Illinois Urbana Champagne. “This is the most weather-free sector of the economy.”

The question is whether these adaptations can keep pace with warming. To determine this, Haltgren and his team saw crops and weather data from 54 countries around the world over the 1940s. They specially saw how farmers adapted to climate change in climate, focus on maize, wheat, rice, cassava, and soybeans. Combined, these crops provide two-thirds of the calories of humanity.

On The Nature Paper, Haltgren and his team have said that in general, adaptation due to climate change can reduce the damage to some crops, but not all.

And the decrease in our food production can be destructive: For every degree of warming, the production of global food may be reduced to 120 calories per person every day. It even considering how climate change can prolong the growing asons touches and encourage the growth of more carbon dioxide plants in the atmosphere.
