What could be the root cause of this hunger in a country that has all it takes including human capitals and natural resources to make a great nation that the whole would will cherish and envy.
As far as I know, there are many factors that cause Nigeria to be hit by famine, for example: extreme weather, conflict, etc. and many other factors, so that all activities are disrupted, starting from agriculture and markets.
With the protracted conflict occurring, many Nigerian people have left their agricultural places and areas, and the behavior of the rebels has really disturbed the people there, By limiting all sectors, it is not surprising if a country is hit by conflict, making them poor without being able to do anything financially or economically.
Moreover, what is even worse is that humanitarian organizations cannot enter conflict areas because especially those areas are already controlled by those who are armed, with no foreign support, so that they do not receive good economic assistance.
The problem is just bad leadership, corrupt politicians who are only interested in looting public fund. With the resources that country like this have weather conditions can't be the reason why their is the level of starvation. If we should check how much that have been invested into agriculture you will see that nothing have been done. The economic crisis that Nigeria is facing right now is as a result of mismanagement of resources. Things can get better if their is a good leadership that can manage the country resources and go after politicians that are looting public fund. Most countries that are facing terrible economic challenge it is as a result of bad leadership and nothing more is the cause.
