Food security is a primary concern and necessity of every nation, and crop diversification is a dynamic tool to ensure the food security in a sustainable way. Crop diversification includes both growing of conventional crops and introduction of new nonconventional crops. Crop diversification is also an efficient tool for mitigating the adverse effects of climate change. In this chapter, authors have discussed various disadvantages of mono-crop culture like disease infestation, abiotic stress, and negative environmental consequences and also discussed how these consequences can be mitigated with crop diversification. Besides all these advantages, in a narrow scope, risk avoidance, land suitability, social norms, income level, and contact with extension officers are key challenges which hinder wide adaptation of crop diversification. Acceptance of new crops in the market is also a challenge. In this scenario, inclusion of oilseed crops and legume crops and the promotion of agroforestry system may be a viable option to adjust as new crops in already adopted cropping systems. But before adaptation of new crops, long-term experiments on the impact of crop diversification on soil properties, farmer income, food security, and global warming should be carried out to exclude the farmers’ risk.
