Final answer:
The strategy developed in the US to intensify global agriculture is the Green Revolution, which began in the 1940s. It included the use of high-yield seeds, expanded irrigation, and more fertilizers and pesticides, greatly boosting food production but also raising criticisms for increasing dependency on intensive capital inputs.
Step-by-step explanation:
The strategy developed in the US that was exported around the world to intensify agriculture is the Green Revolution. This agricultural movement began in the 1940s in Mexico and saw widespread international adoption in the 1950s and 1960s. It involved the development and use of high-yield variety (HYV) seeds for crops such as wheat and rice, expanded irrigation infrastructure, and increased application of artificial fertilizers and pesticides. Despite its role in significantly boosting food production, the Green Revolution is also critiqued for increasing dependency on capital-intensive inputs and exacerbating social inequalities in farming communities.The Green Revolution was crucial in preventing the global famines that were predicted in the late 1960s, thanks to the significant improvements in agricultural yields. The innovations that drove this leap in productivity can largely be credited to scientist Norman Borlaug, who developed disease-resistant and higher-yielding varieties of crops, primarily wheat, which transformed agriculture especially in developing nations facing population growth and hunger.
