• Globalized agriculture• Economy and regulatory

practices are global in scope

• Trade and financial organizations

• Decline in some forms of agriculture, for example, shifting cultivation and family farms

• Subsidies to food producers

National and International Agricultural Policy

• Why have domestic and international policies?

• Impacts• World Trade Organization

(WTO)• Agricultural subsidies

Figure 9.19 Direct subsidies for animal products and feed.

Apply your knowledge: What are some reasons different groups would protest national agricultural policies? Think about how policies are set and the role of the WTO, and how GMOs might threaten indigenous seed varieties.
