Answer: Please refer to Explanation
Explanation:
Undernourishment
This is defined as being unable to take the required amount of food and nutrients for energy that the body needs per day. This has to have gone on for a year for it to be classified as Undernourishment.
Desertification
This refers to a situation where land that was once fertile looses that fertility and instead begins to become more desert like. This is very prevalant in the Sahel region of Africa and can be caused by droughts and inefficient farming practices.
Food Security
This is defined as the access to sufficient, safe, and nutritious food at all times needed to be able to sustain the human body by meeting the minimum amount of recommended energy that the body requires to function.
The Sahel is an area immediately south of the Sahara Desert. It is semi-arid in nature and is prone to prolonged periods of drought.
When this drought occurs it tends to cause soil that was once fertile to begin to turn into a desert like soil due to the soil not getting water for such a prolonged period of time.
When there is a lot of fertile land used for farming lost to desertification then the people in those areas cannot farm and get food needed to survive. This causes Food Security issues because people do not have access to food that they require to survive.
Should this happen and the people there go through Food security crisis, they will become undernourished as they are unable to take the recommended amount of food necessary.
