Epidemiological Transition Model
• 1. Modernisation and development creates epidemiological transition
• 2. With modernisation, or increasing affluence, comes a different range of illnesses
• 3. Initially there were 3 stages ranging from pestilence to ‘human induced illness’
• 4. There are 3 variations of the basic model which correlates to different areas and the speed to which they pass through the stages ‘western’, ‘accelerated’ and ‘delayed’

Famine
• F.A.O = Food and Agricultural Society• 800million have chronic malnutrition• Enough food is produced globally to provide
2,700calories to everyone each day• Malnutrition = a condition from dietary
deficiency• Undernourishment = Not eating enough food
over a period of time

Famine
• We live in a globalised world – why isn’t everyone getting their fair share?
• Natural events and human mismanagement• May be food exported but not that individual families
can afford
3 Reasons why famine occurs:• DROUGHT• ARITHMETIC CROP GROWTH• PRICE INFLATION

Short Term Solutions to Famine
• SHORT TERM• Usually carried out by N.G.Os such as charities.
Aquinas alone raises significant amounts of money for CAFOD who respond to famines
• Overdependence can be a problem with short term aid – there is only a limited supply and it might damage the local agricultural economy
• TASK: To remember the issues relating to famine relief C.D.F.I.C.T – stick on walls

Long Term Solutions to Famine
• Making famine help more productive• Usually comes in farming – SYNTHESIS• Using improved technology or fertilisers• Getting the produce to markets more quickly
whilst it is still fresh and desirable• Easing international trade and cancelling
national debts• Drop the Debt – Make Poverty History
