From Tech Times: “As average global temperatures begin to rise due to human activity, scientists say the drastic effects of climate change continue to take effect all over the world.” (Umm, what effects?)
“One of the most severely affected sectors is the field of agriculture. In the past decades, extreme weather conditions caused by climate change have disrupted global food production. “The food system is already stressed in many ways,”said Professor Navin Ramankutty of the University of British Columbia, an expert on global food security and sustainability.
Ramankutty is the senior author of a new study featured in the journalNature, which examined the link between weather-related disasters and food production.
Along with a team of researchers from UBC and McGill University, Ramankutty found that extreme heat waves and droughts have reduced global cereal harvests such as maize, wheat and rice by 10 percent in a span of 50 years.”
From the U.S. Department of Agriculture:
Last year set records.
Now both Ramankutty and the USDA could in theory be correct–we could have set records for production and still been 10% below our potential harvests.
But given that between a quarter and a third of the world’s food either rots or is eaten by rodents and insects before it gets to the table and almost a quarter is thrown away unconsumed, perhaps focusing on harvests is a tad misguided…
And given that in the developing world agricultural productivity is far lower than found in the West, perhaps better farming practices and procedures would more than compensate for the effects of climate change to date and maybe even into the future.
Finally, given that increased CO2 has helped the planet green by about 15%, shouldn’t we note the good along with the bad?
Don’t get me wrong. Food security is a serious issue in a world with a rapidly growing population, a changing climate and a diminishing habitat for non-domesticated species,both animal and plant.
But focusing on an issue that has not materially affected the well-being of humanity or our ability to feed ourselves isn’t contributing to the discussion. Instead it is distracting us from the more serious issue while pandering to the obsession of the moment.
