In chapter 5, “The Technology Ticket,” contributing author Uris Baldos urges acceptance and investment in “precision agriculture” to provide for a burgeoning global population.
The Green Revolution of the 20th century began with Norman Borlaug’s development of a short-statured, large-grained wheat.

CMMYTAs an Iowa farm boy who lived through the Great Depression, Norman Borlaug viscerally understood the toll of poverty and hunger. It fueled his determination to feed a global population that was increasing exponentially—and his tenacious belief that the way to do so was by boosting crop yields.
Trained as a plant pathologist, Borlaug joined the Rockefeller Institute–funded Cooperative Wheat Research and Production Program in Mexico (a precursor to CIMMYT, the International Maize and Wheat Improvement Center) in 1944 to develop varieties resistant to a fungal pathogen called wheat rust. (See “Putting Up Resistance,” page 34.) He succeeded, but the tall varieties he worked with tended to fall over, or “lodge,” in the wind or rain when the seed heads grew large. In 1953, Borlaug obtained a Japanese variety of semidwarf wheat called Norin 10, which was two feet shorter. He first bred Norin 10 with local rust–resistant Mexican strains, and eventually crossed the hybrids with wheat varieties from other countries. This painstaking work continued for years, but yielded wheat with plump heads and sturdy stems that avoided lodging.
To speed up field testing, Borlaug grew two crop rotations per year, shuttling seeds between his summer fields at the higher elevations of central Mexico and his winter fields near the coast of Sonora, to the north. This incidentally bred photoperiod-insensitive strains that could be grown at nearly any latitude. Altogether, his efforts vastly improved the productivity of farms around the world, especially in poor and hungry countries. His wheat improvements are credited with saving a billion people from starvation.
“There are no miracles in agricultural production,” Borlaug said in his 1970 Nobel Peace Prize lecture. “The Green Revolution in India and Pakistan . . . is based on sound research, the importance of which is not self-evident at first glance. For, behind the scenes, halfway around the world in Mexico, were two decades of aggressive research on wheat.”
Jesse Dubin, who worked with Borlaug at CIMMYT for more than 25 years, says Borlaug insisted that field work was the best way to understand a plant. “Borlaug used to say, ‘If you don’t go out in the field and talk to the plants, the plants won’t talk to you,’” Dubin recalls.
Although Borlaug was admired by agronomists, and even his close colleagues were awed by what he had achieved, detractors say that Borlaug contributed to a loss of traditional farming and the spread of monoculture, herbicides, soil erosion, and an unsustainable dependency on industrial farming practices.
On what would have been Borlaug’s 100th birthday earlier this year, legislators unveiled a statue of him in the US Capitol. But Julie Borlaug says her grandfather was less interested in celebrating his past achievements and more concerned about solving the next generation of agricultural challenges. After thanking the crowd, “he would have turned to everyone in the audience, with his finger pointing, and he would have given them marching orders,” she says. “First and foremost would have been, ‘Less talk, more action.’”

It just seems to me that "loss of traditional farming practices" could be a code word for "keep them poor and starving." Wise use of new varieties of crop plants should be an attainable goal which should result in narrowing the gap between the haves and the have nots in the world.

For example, it is not clear to me why these varieties of wheat would in themselves led to industrial agriculture. New machines and capital concentration may have been enough.
In addition to the criticisms mentioned, the book Wheat Belly claims that these new varieties are very different from the old varieties in more than stem height and productivity. Wheat Belly claims that the new varieties also have very different carbohydrate and protein structures. In fact, these new varieties led to increase in celiac disease and the new muffin shape of American middles. In fact, that these new varieties and the change to low fat high carb diets led to the obesity epidemic in the US.
