Before proceeding, it is important to note the importance of the law of diminishing marginal returns in agriculture.
Transport and Infrastructure
Wars and conflicts lead to a decrease in food production (CE2006-4aiii):
- People are forced to leave their farmland to become refugees. The labour supply for farming drops.
- Capital is lost.
- Agricultural production facilities, irrigation systems, farmlands, infrastructure and transport are destroyed.
- Resources are drained for military purposes, so less capital is used to develop farming.
All these reduce food production. In addition:
- It is hard for international aid to reach war zones, so emergency food supply is disrupted.
