Document Summary

Almost 1 billion people don"t get enough to eat on a regular basis. Approximately 1 billion people are overweight or obese. Diseases of malnutrition: marasmus: severe deficit of energy, protein & carbohydrates, kwashiorkor: protein & micronutrient deficiency, excess fats, carbohydrates, calories, diabetes, heart disease, obesity. Rural poor in developing countries: often have no electricity and no safe drinking water, health, education and sanitation services are poor, often directly involved in producing food, many have no land of their own and work seasonally. Urban poor: no means to produce food; have few resources to buy it. Victims of catastrophes: floods, droughts, earthquakes, etc. force people to abandon land. Why can"t we feed everyone: farmers today produce more than enough calories to feed everyone. Food security means : ensuring that all people have physical and economic access to the quantity and quality of food they need to work and function normally from local, non- emergency sources.
