HKDSE Geography/M5/Cultural Factors in Agriculture

Economic Factors
Before proceeding, it is important to note the importance of the law of diminishing marginal returns in agriculture.

Political Stability
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.
