Water scarcity, population growth, and shifting agricultural land or crops toward biofuel production can all reduce the food available to people and increase famine risk. Increased crop diversification generally spreads risk across different crops and can make food supplies more resilient, so it is not a factor increasing the risk. The best answer is increased crop diversification.
