Averting an Imminent Food Crisis: The Need for Alternative Crops

Statistics published by the UN Population Division, show that the estimated world human population is expected to increase from 2.5 billion in the 1990s to 8.5 billion by 2025 and projected to 9.2 billion by 2050. These estimates having always been associated with the challenges of environmental sustenance and food supply now show that food production must increase by 60- 70% in order to meet world demand and to minimize malnutrition. How will this increase be realized? Would this achievement be different from the promise of the 1990s?
