UN climate report: Change land use to avoid a hungry future
Human-caused climate change is dramatically degrading the Earth’s land and the way people use the land is making global warming worse, a new United Nations scientific report says. That creates a vicious cycle which is already making food more expensive, scarcer and less nutritious.
“The cycle is accelerating,” said NASA climate scientist Cynthia Rosenzweig, a co-author of the report. “The threat of climate change affecting people’s food on their dinner table is increasing.” ...
"The stability of food supply is projected to decrease as the magnitude and frequency of extreme weather events that disrupt food chains increases,” the report said.
In the worst-case scenario, food security problems change from moderate to high risk with just a few more tenths of a degree of warming from now. They go from high to “very high” risk with just another 1.8 degrees Fahrenheit (1 degree Celsius) of warming from now.
“The potential risk of multi-breadbasket failure is increasing,” NASA’s Rosenzweig said. “Just to give examples, the crop yields were effected in Europe just in the last two weeks.” ...
... But better farming practices — such as no-till agricultural and better targeted fertilizer applications — have the potential to fight global warming too, reducing carbon pollution up to 18% of current emissions levels by 2050, the report said.
If people change their diets, reducing red meat and increasing plant-based foods, such as fruits, vegetables and seeds, the world can save as much as another 15% of current emissions by mid-century. It would also make people more healthy, Rosenzweig said....
