Global food Flashcards
Areas of surplus and deficit/global food, security risk
On average people need around 2500 cal a day to live a healthy life
Calorie intake is very uneven across the world
The highest calorie intake is in North America and parts of Europe. Obesity is a growing problem
The lowest calorie values are found in Africa together with isolated countries in the Middle East and Asia. Many countries suffered serious food, shortages, leading to malnourishment and undernourishment in most serious cases, famine and starvation time result.
There are also huge variations in calorie intake with an individual countries, both rich and poor
Areas of food insecurity
Predominately, Africa, the Middle East, part of Asia
Areas of food security/surplus
Much of the rest of the world enjoy food, security, H ICs, North America and Europe
Why is food consumption increasing?
Economic development
Population growth
Economic development on the consumption of food, increasing
Economic development, such as in China and India increases the demand for food.
People become richer, they can afford to buy a greater quality and quantity of variety to food
Richer people tend to eat more than four people, so as a country develops, the demand for food increases
Die often change is with an increase of meat consumption in China is a percentage of meat in diets rose from 6% in 1981 to 17% in 2011 life suck a fat cereals to produce meat for people T where is it? Used to be people who mostly eat cereals
Demand for convenience and highly processed rate increases with economic development as people have less time to grow their own food
Population growth
Population growth increases the pressure on free production and supply. The worlds population has grown rapidly since 1950 and its current level is about 8 billion almost always growth has been an LIC is an NEE is wifey. Production is low and many people suffer from food insecurity
The fastest population growth is two. 51% . per year. This is the constant suffering from a nice food insecurity in my calorie intake.
What factors affect food supply?
Climate
Technology
Pests and diseases
Water stress.
Conflict.
Poverty.
How does Climate affect food supply
Droughts and floods climate change can have catastrophic effects on food production
For example, in sub-Saharan Africa, many farmers are dependent on seasonal rains, which sometimes fail recent drought in Ethiopia and Somalia. Of course, severe food, shortages, and migration droughts could lead to desertification and salinisation.
Patterns of rainfall victory, changing as a result of climate change. Some areas of the world may produce more food. Where is other areas may suffer from more frequent droughts and floods.
How does technology affect food supply?
Food supply in distribution in low income countries can be affected by the lack of
Farm, machinery – low yields.
Irrigation.
Storage facilities
Transport infrastructure – to distribute food.
Processing facilities to preserve food.
How to pests and diseases affect food supply
M Many tropical regions suffer from past and diseases and they often lack of money to protect crops and livestock.
Locusts can devastate food crops.
Cattle can be infected by airborne bacteria, causing bovine pleuropneumonia.
Import societies, disease can reduce peoples captivity to be productive.
Water stress affecting food supply
There is a serious issue. A mini Elysees by climate change is expected to cause more damage. The lack of a security together with you out reduces free production. HICs can afford expensive water transfer scheme or irrigation projects where is L ICs cannot
Conflict affecting food supply
E.g. Somalia, Syria, South Sudan
What does wraps the distribution of food?
Farmland, maybe minned
people forced to move away
Water supplies become polluted
Food aid may be restricted areas of military conflict
Poverty on food supply
CAnnot afford high quality seeds fertilisers machenary
So produce less food
Suffer from malnourishment under nutrition which reduces their ability to work
What are the impacts of food insecurity?
Famine in undernutrition
What’s the weather like version?
Rising prices
Social unrest
Famine and under nutrition as an impact of food security
Famine can lead to malnourishment and nutrition and the weekend immune system
Are you an estimate to over 800, million people suffer from chronic malnourishment, most of whom live in low income countries
