Objective 1: Identify global patterns of calorie intake as one measure of food availability.
In this section we will investigate the concept of "food security" and analyse ares of the world that have a food surplus and a food deficit. To start off with here are a few questions on the key terms and concepts that we will need in this section. These questions develop into an old friend - Thomas Malthus, who's theories on population growth and agricultural production are particularly relevant to this section of the option.

Objective 2: Explain how the development of agricultural systems have lead to an increase in food supply in some areasScientific and technological innovations, the expansion of the area under agriculture and the growth of agribusiness have all played their part in increasing food production. The Green revolution showed how these changes can be maximise but also highlighted some of the associated issues. In this section we will explore the ways in which humans have increased the yields of crops to build food supply. |
Objective 3: Examine the environmental, demographic, political, social and economic factors that have caused areas of food deficiency and food insecurityWe will explore this with brainstorm initially and lead into some more detailed work by looking at a case study - famine in Ethiopia which we will use to build our essay skills (don't worry, we won't be writing another one, you'll just be planning it)

Objective 4: Examine the impacts at a variety of scales of trade barriers, agricultural

Objective 5: Evaluate the relative importance of food aid, free trade

Objective 6: Examine the concept of sustainable agriculture in terms
of energy efficiency ratios and sustainable yields
Sustainable agriculture is the ability of a farm to produce food indefinitely, without causing irreversible damage to ecosystems.
