The man in focus is Norman Borlaug, theFather of the 'Green Revolution', who died on September 12, 2021 at age 95. Norman Borlaug spent most of his 60 working yearsin the farmlands of Mexico, South Asia and later in Africa,fighting world hunger, and saving by some estimates up to a billion lives in the process. An achievement, fit for a Nobel Peace Prize.Early Years"I'm a product of the great depression" is how Borlaugdescribed himself. A great-grandson of Norwegian immigrants to the United States, Borlaug was born in 1914 and grew up on asmall farm in the northeastern corner of Iowa in a town calledCresco. His family had a 40-hectare ( 公顷) farm on which they grew wheat, maize ( 玉米) and hay and raised pigs and cattle.Norman spent most of his time from age 7-17 on the farm, evenas he attended a one-room, one-teacher school at NewOregon in Howard County.Borlaug didn't have money to go to college. But through a Great Depression era programme, known as the National Youth Administration, Borlaug was able to enroll in the Universityof Minnesota at Minneapolis to study forestry. He excelled in第 2 页 共 32 页studiesand receivedhisPh.D.inplantpathology( 病理学) andgenetics in 1942. From 1942 to 1944, Borlaug was employed as a microbiologist at DuPont in Wilmington. However, following the December 7, 1941 attack on Pearl Harbor, Borlaug tried to join the military, but was rejected under wartimeIn MexicoIn 1944, many experts warned of mass starvation in developing nations where populations were expanding fasterthan crop production. Borlaug began work at a Rockefeller Foundation-funded project in Mexico to increase wheat production by developing higher-yielding varieties of the crop. It involved research in genetics, plant breeding, plant pathology, entomology ( 昆虫学 ) , agronomy ( 农 艺 学 ) , soil science, and cereal technology. The goal of the project was to boost wheat production in Mexico, which at the time was importing a large portion of its grain.Borlaug said that his first couple of years in Mexico were difficult. He lacked trained scientists and equipment. Native farmers were hostile towards the wheat programme because ofserious crop losses from 1939 to 1941 due to stem rust.Wheat varieties that Borlaug worked with had tall, thin stalks. While taller wheat competed better for sunlight, they第 3 页 共 32 页had a tendency to collapse under the weight of extra grain -a trait called lodging. To overcome this, Borlaug worked on breeding wheat with shorter and stronger stalks, which couldhold on larger seed heads. Borlaug's new semi-dwarf, disease-resistant varieties, called Pitic 62 and Penjamo 62,changed the potential yield of Mexican wheat dramatically. By1963 wheat production in Mexico stood six times more than that of 1944.Green Revolution in IndiaDuring the 1960s, South Asia experienced severe drought condition and India had been importing wheat on a large scalefrom the United States. Borlaug cameto India in 1963 along with Dr. Robert Anderson to duplicate his Mexican success in thesub-continent. The experiments began with planting a few of the high-yielding variety strains in the fields of the Indian Agricultural Research Institute at Pusa in NewDelhi, under the supervision of Dr. M. S. Swaminathan. These strains were subsequently planted in test plots at Ludhiana, Pantnagar,Kanpur, Pune and Indore. The results were promising, but large-scale success, however, was not instant. Cultural opposition to new agricultural techniques initially prevented Borlaug from going ahead with planting of new wheat strains in第 4 页 共 32 页India.By 1965, whenthe droughtsituationturnedalarming,theGovernment took the lead and allowed wheat revolution to move forward. By employing agricultural techniques he developed in Mexico, Borlaug was ab。
