Answer:
governments having limited the incentive for increase by keeping prices low
Explanation:
The Horn of Africa and the Sahel a re regions dominated by arid and semi-arid climate types. This makes these regions very limited when it comes to agricultural production. The climate is not suitable in most of these regions for large scale production, so lot of modifications and investments are needed in order to transform the land. Big problem is also the infrastructure, as it is relatively bad condition, so even what is produced is usually consumed locally because the products can reach the markets in saleable condition. The population growth is quicker than the agricultural growth, so there's a very big problem with malnutrition. The governments are putting lot of effort in this sector, but they are very limited financially, so it is going very slowly.
Answer:
The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The passenger aircraft would take 
years to reach the gallactic center.
Explanation:
The distance to the sun from the Earth is approximately equal to 
, if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:
(1)
Where:
- Travelled distance, measured in kilometers.
- Speed of the passenger aircraft, measured in kilometers per second.
- Travelling time, measured in seconds.
If we know that 
and 
, then the travelling time is:
The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The distance between the Earth and the galactic center is approximately equal to 
. If the passenger travels at constant speed and if we know that 
and , then the travelling time is:
The passenger aircraft would take years to reach the gallactic center.
