The document discusses global hunger trends, highlighting that nearly 870 million people suffer from chronic undernourishment, particularly in developing countries. It emphasizes that while world food production has increased, issues such as poverty, political instability, and climate change hinder access to food. The report also examines the definitions of food security and insecurity, the impact of nutrient deficiencies, and the role of technological advancements in addressing these challenges.

•Nearly 870 million people of the 7.1 billion people in the world (or 1 in 8) were suffering from chronic undernourishment in 2010 – 2012
–Live in the developing countries representing 15% of the population of developing countries.
–16 million people undernourished in developed countries

10. cont. Hungry people in the world
•The number of undernourished people decreased 30% in Asia and the Pacific, from 739 million to 563 million
–The prevalence of undernourishment decreased from 23.7% to 13.9%.
–Due to socio-economic progress in many countries.
•Latin America and the Caribbean also made progress, falling from 65 million hungry in 1990 – 1992 to 49 million in 2010 – 2012
– prevalence of undernourishment dipped from 14.6% to 8.3%, but the rate slowed recently.

11. cont. Hungry people in the world
•The number of hungry grew in Africa, from 175 million to 239 million
–Nearly 1 in 4 are hungry
–Sub-Saharan Africa – hunger rising 2% per year since 2007, reversing modest progress achieved
•Developed regions – hunger rise from 13 million in 2004 – 2006 to 16 million in 2010 – 2012
–Reversing a steady state decrease in previous years from 20 million in 1990 - 1992

14. Does the world produce enough food?
•YES!
•World agriculture produce 17% more calories per person today than it did 30 years ago, despite a 70% population increase.
•Enough to provide everyone in the world with a least 2720 kcal per person per day.
•Principle problem – many people in the world do not have sufficient land to grow, or income to purchase enough food

23. What causes of hunger?
•Natural disasters
•Political and economic instability
•Inflation, high food prices
•Production shortfall
•Poverty
•Climate change
•Diminishing natural resource
•Infectious disease (e.g. AIDS pandemic)
•Low levels of education and literacy
•Inadequate application and distribution of technology

24. Food security
24

25. Food security
•Definition of food security:
–Access to enough food to sustain a healthy and active life
•High food security
–No indication of food-access problems or limitations
•Marginal food security
–One or two indication of food-access problems but with little or no change in food intake
25

26. Food insecurity
•Definition of food insecurity:
–Limited or uncertain access to foods of succificient quality or quantity to sustain a healthy and active life
•Low food insecurity
–Reduced quality of life with little or no indication of reduced food intake; formerly known as food insecurity without hunger
•Very low food insecurity
–Multiple indications of disrupted eating patterns and reduced food intake: formerly known as food insecurity with hunger

28. Hunger and Malnutrition
28

29. Hunger concepts and definition
•Hunger
–A condition in which people lack macronutrients and micronutrients for fully productive, active, and healthy lives
–Can result from insufficient nutrients intake or from impaired absorption of the required nutrients in the body (also called hidden hunger)
•Malnutrition
–Is a physical condition in which people experience either a deficiencies of nutrients (undernutrition) or an excess of certain nutrients (overnutrition)
29

30. Nutrient deficiencies and its threats to food security
30
•Protein and calories
–Problems of PEM or undernutrition – the main manifestation of malnutrition in developing countries
–Determined based on the prevalence of underweight, stunting, and wasting
–Leading to marasmus and kwashiokor
•Fat
–Low quantities of total fat being consumed in poor countries esp. Sub-Saharan Africa and South Asia
–About 19 countries falling below the minimum recommendation of 15% dietary energy supply from fat

31. cont. Nutrient deficiencies and its threats to food security
31
•Vitamin A
–Vitamin A deficiency leading to permanent blindness
•Iodine
–Inadequate iodine nutrition among adults
–Mental handicap as a result of iodine deficiency among children
–Children born with irreversible brain damage due to their mothers lacking iodine before and during pregnancy

32. cont. Nutrient deficiencies and its threats to food security
32
•Iron
–Most iron deficiency cases leads to anaemia
–¼ of the worldwide population having anaemia
–Preschool-age-children having moderate or severe anaemia (Hb level < 10 g/dL) esp. in Africa and Asia
•Zinc
–Zinc deficiency is a major determinant for diarrhoeal disease, pneumonia and malaria, low birth weight and stunted child growth
–Causing death
