Which event resulted in developing countries being able to produce higher-yielding, disease- and insect-resistant varieties of small grain?

The development of higher-yielding, disease- and insect-resistant varieties of small grains is primarily attributed to the Green Revolution. This movement began in the mid-20th century and was characterized by the introduction of advanced agricultural technologies, including improved seeds, the use of chemical fertilizers, pesticides, and irrigation practices. These innovations significantly enhanced crop productivity, particularly in developing countries, where agricultural practices were often less advanced.

During the Green Revolution, scientists and agricultural researchers focused on breeding programs that led to the creation of new varieties of staple crops, making them more robust against diseases and pests. This increased resilience not only allowed for greater food security but also helped countries to boost their agricultural productivity, ultimately contributing to economic development and improved living standards.

The other options don't directly relate to the specific advancements in crop science and agricultural productivity that define the Green Revolution. The Industrial Revolution, while crucial in changing labor and machinery in agriculture, predates the breakthroughs associated with crop varieties. Globalization refers more to the integration of economies and cultures rather than agricultural advancements alone. The Greenhouse Initiative typically relates to environmental policy rather than the specific agricultural improvements seen during the Green Revolution. Thus, the Green Revolution stands out as the event that directly led to the advancements in small grain production in
