  1. The Nature of Hunger Global Perspective on Food

  2. Vocabulary of Food and Hunger • Nutrient – a chemical that an organism requires in order to live and grow, usually consumed from the external environment • Famine – a severe short-term shortage of food, caused by temporary failure of food production or distribution • Human or natural causes • Starvation – extreme hunger occurring over a long period of time; consistent failure to receive essential nutrients from food (body breaks down its own tissue to try and obtain these nutrients)

  3. Malnutrition – medical condition of poor health caused by diet (too much or too little of essential nutrients) • Under-nutrition and over-nutrition • Chronic (consistent) Hunger – results from an unstable food supply, can lead to increased vulnerability to illness, poor physical and mental development, high infant mortality

  4. Equal Area Projection of the Earth

  5. Undernourishment, 1990 (territory size shows percentage of undernourished)

  6. Undernourishment, 2000

  7. Introduction to Agriculture • Agriculture relies on a number of different factors • Temperature, moisture, soil type, landscape (hills or flat land), insect populations, competing species (“weeds”) • Humans have adjusted our environment to sustain agriculture • Irrigation (to water plants), soil fertilizers, chemical fertilizers, pesticides, genetically modifying plants

  8. Types of Agriculture Cash Cropping • Produce only 1 or 2 crops on large farms • All produce sold on local/world markets, rarely consumed directly by farmer Extensive Farming • Large amount of land • Less labour, fewer inputs (fertilizers, pesticides) • Less yield per hectare, but large overall production Subsistence • Food is grown to meet immediate needs of farmer/family • Often small scale farms • Less developed areas of the world Intensive Farming • Small amount of land • Lots of manual/machine labour, fertilizers, pesticides and irrigation • Produce lots of food in a small area (high yield per hectare)

  9. Intensive Farming Subsistence Farming Cash Cropping Extensive Farming
