According to the World Food Summit, food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. This involves four conditions:
ÃÂ§Adequacy of food supply or availability;
ÃÂ§Stability of supply, without fluctuations or shortages from season to season or from year to year;
ÃÂ§Accessibility to food or affordability;
ÃÂ§Quality and safety of food.
The world produces enough food to feed everyone. However, there are countries, regions within countries, villages within regions, households within villages and individuals within households that are not able to meet their food needs.
Food security requires an available and reliable food supply at all times. Individuals and households must have access to sufficient, safe and nutritious food both in quantity and in quality to meet their daily dietary requirements for a healthy and productive life.
Without any doubt, famine and hunger are the seriously problems of the world today, food security deal with the same, most basic, need of life: food. I am not saying that they are the same concepts, food security indicates the availability of food; while famine and hunger refer to the effects of the non-availability of food. But the fact is, over 800 million human beings do not have enough to eat in a world that produces enough food to feed every man, woman and child. So, famine and hunger, in other words, are the result of food insecurity. For this reason, food security has became an important issue to be achieved and it is the only way to help the world people keep away of famine and hunger!
To achieved food security, we need to have a big understanding of the principally that caused food insecurity firstly.
