Other factors that contributed to crop failures in Vietnam during the war included:
- The destruction of irrigation systems and other agricultural infrastructure.
- The displacement of farmers from their land.
- The use of chemical defoliants and herbicides.
- The disruption of trade and transportation networks.
The crop failures in Vietnam during the war had a devastating impact on the country's food supply. They also contributed to the spread of disease and malnutrition, which further weakened the Vietnamese population and made it more vulnerable to the effects of the war.
