my new decision on research

Because there is less information I can find in the library, so I decide to change my topic. The new topic is food shortage.
Question:
1. What is the food situation in different parts of the world?
2. How serious is the food shortage in developing countries?
3. Is there famine in developed countries?
4. What steps are being taken to solving food shortage---organization?
5. What are the projection are made for the future?
